Alimentação como problema no espaço mediático:análise de editoriais da imprensa gráfica argentina, 2002-2008

En los últimos años en Argentina se ha venido debatiendo en diferentes ámbitos la matriz productiva y alimentaria, y sus principales consecuencias. El objetivo del artículo es analizar el proceso de construcción de la problemática alimentaria luego de la crisis de 2001 hasta 2008, al identificar y analizar las representaciones asociadas con ella en los discursos de la prensa gráfica desde un enfoque cualitativo. Para ello, se seleccionaron dos medios gráficos nacionales y se analizaron sus editoriales, apelando a la metodología del análisis del discurso. El propósito fue analizar esos debates en el ámbito mediático, considerado actor clave del espacio público y lugar donde se construyen temas y problemas en los que subyacen diversas representaciones sociales a partir de las cuales se disputan posicionamientos sobre la matriz alimentaria, sus consecuencias, los actores involucrados, el rol del Estado y las políticas públicas.

The aim of this article is to analyze the construction of the food problem as a public issue after the crisis of 2001-2008, by identifying and analyzing the representations associated with it in the graphic press. To this end, we selected two national print media and analyzed their editorials, appealing to the methodology of discourse analysis. The purpose was to analyze these debates in the media field, which is considered as a key player of the public space and a place where topics and problems are constructed. In addition we assume media as a space for diverse social representations, from which the positioning of the food matrix as an issue, its consequences, the actors involved, the role of the state and public policies are disputed.Fil: Demonte, Flavia Carolina.

Evidentials dizque and que in Spanish : Grammaticalization, parameters and the (fine) structure of Comp

In this paper we study one type of Spanish que (the equivalent to the complementizer “that”) that can be shown to belong into the crosslinguistically restricted list of evidentials. In particular, we will claim that it encodes the (most basic) marks of nonfirst- hand or indirect (reported) evidence. Our point of departure is certain (apparently) independent clauses of Spanish headed by an overt complementizer (que). Some tests will be presented that support the idea that that one type of que introducing a well specified subset of root sentences shares most of the properties that have been claimed to characterize reportative evidentials in languages such as Quechua (Faller 2002, 2006). As for the properties of reportative que, it will be further shown that it does not encode any features related to epistemic modality (reliability or (im)probability) and we will propose that it is better analyzed as an illocutionary operator, affecting the illocutionary force (in line with Faller 2002 among others) and not as an epistemic modal (Izvorsky 1997 among others). In order to determine the nature of this reportative element and its origin, we contrast it with an old Spanish form, dizque, which exists nowadays in certain modern American varieties. This particle also has the properties of an evidential but behaves as an epistemic modal. In the last sections, we will propose that both evidential particles (que and dizque) are the result of a process of grammaticalization (i.e. ‘upward reanalysis’, or categorial change, of functional material, in the sense of Roberts and Roussou 2003) of the complex structure headed by a communication verb, dicen que “they say that”. We will tentatively describe such process and introduce a hypothesis as to the nature and role of the parameter involved in the claimed reanalysi

Force and finiteness in the Spanish complementizer system

The goal of this paper is to show that the structure of CP in Spanish is more complex than it appears to be in most descriptive approaches. In particular, we analyze five types of constructions, which are quite extended in all dialects of Spanish but which have remained almost unaddressed in grammatical studies. These data clearly reveal a complex structure for Spanish CP both in root and embedded clauses: They involve sentences with more than one instance of a complementizer heading the clause, sentences where a wh-element (interrogative or exclamative) can be preceded or followed by the complementizer que ‘that’, and matrix sentences (obligatorily) introduced by an explicit Comp, among other cases. Our point of departure will be the studies on the so called “sentence left periphery” (Rizzi 1997) containing an upper limit, ForceP and a lower limit, FinP. Our claim will be that in Spanish there are two instances of que: que1 and que2 which are respectively generated in the upper and in the lower part of the sentence periphery. In addition, we will provide data suggesting that there might even be a third instance of que, a kind of “reinforcement” of Force. In this sense Spanish resembles some languages which are very different from the typological point of view.The research behind this paper has been financed by the Spanish DGI (MEC) through a grant to the Project BFF2003-06053

Wood capillarity and deacetylation during eucalyptus alkaline impregnation. Suphidity effects and comparison between transverse directions

The relative ion transport capacity of wood, i.e., the Effective Capillary Cross Sectional Area (ECCSA), is determined in this work based on the analogy with the relation between the electrical conductivities of wood and liquid medium. Wood is treated under different conditions and then the corresponding ECCSAA (effective capillarity under alkali) is estimated from the value obtained in an inert solution at room temperature (ECCSAInert). The difference between radial and tangential ECCSAA-values can be considered similar irrespectively of pH, time, temperature and the presence of sodium sulfide in the treatment liquor. The results show that the degree of removal of native acetyl groups from hardwood O-acetyl-glucuronoxylan is determinant of a physical characteristic, the ECCSAA. A kinetic expression for Eucalyptus wood deacetylation is validated and used to establish the relationship between the acetyl content and ECCSAA in both directions.Fil: Inalbon, Maria Cristina.

Iodine Staining of Escherichia coli Expressing Genes Involved in the Synthesis of Bacterial Glycogen

The presence of intracellular glycogen can be detected by the following iodine staining technique. Cells with glycogen stain dark brown, whereas in its absence they remain with a pale yellowish color. It is hypothesized that iodine atoms fit into helical coils formed by the α-polyglucan to form a coloured glycogen-iodine complex. Here, we have studied the expression of Streptococcus mutans (S. mutans) genes that control the biosynthesis of this polysaccharide. Thus, we expressed glgC and glgD genes coding for both ADP-Glc pyrophosphorylase subunits in Escherichia coli (E. coli) AC70R1-504 cells to complement the deficient accumulation of glycogen by this strain. In control cells or in those where an inactive protein was expressed, the synthesis of the polysaccharide was undetectable by this iodine staining technique.Fil: Demonte, Ana M..

Global Climate Change, The Political Economy, and Development A Case Study: The Kingdom of Tonga

Globalization has created prosperity and growth for many of the countries across the globe especially in the Global North, which experience some of the greatest benefits of globalization while being the least affected by its negative impacts. Small island nation states tend to experience these negative impacts of globalization more often than the states that are fueling these trends. Globalization has many meanings, but the most agreed upon definition is the increasing interaction between people and corporations due to advances in transportation and communication technology. These advances have created a more interconnected world where trade, and culture have become international in their scope. Though it has been called an economic process globalization has grown to encompass multiple aspects of modern society (Albrow, King, 1990)

Soybean glycinin improves HDL-C and suppresses the effects of rosuvastatin on hypercholesterolemic rats.

Background: This study was an investigation of the effects of ingesting a daily dose of isolated glycinin soy protein (11S globulin), in association with rosuvastatin, on the control of hypercholesterolemia in experimental animals. Methods: Male Wistar rats were kept in individual cages under appropriate controlled conditions of temperature, light and humidity. The animals were divided into five groups (n = 9): 1) standard (STD): fed on casein as protein source; 2) hypercholesterolemic (HC): STD plus 1% cholesterol and 0.5% cholic acid; 3) HC+11S: hypercholesterolemic + glycinin (300 mg/kg/day); 4) HC+ROS: hypercholesterolemic + rosuvastatin (10 mg/kg/day); 5) HC+11S+ROS: HC diet, the 11S protein and the drug in the doses given in (3) and (4). The protein and the drug were administered by gavage for 28 days. The results indicated that the addition of 1% cholesterol and 0.5% cholic acid induced hypercholesterolemia in the animals without interfering with their weight gain. Results: A single daily dose of glycinin contributed an additional 2.8% of dietary protein intake and demonstrated its functional role, particularly in raising HDL-C, decreasing triglycerides in the liver and improving the atherogenic index in animals exposed to a hypercholesterolemic diet. Conclusion: Most of the beneficial effects of the isolated treatments disappeared when the drug (rosuvastatin) and the protein (glycinin) were taken simultaneously. The association was shown not to interact additively, as noted in the plasma levels of total cholesterol and non-HDL cholesterol, and in the significant increase of cholesterol in the liver. Studies are in progress to identify the effects of peptides derived from the 11S globulin and their role in cholesterol metabolism
