The "gender perspective" seems to be the key to solve a series of pressing problems on the most varied issues. All the expectations projected on it make it an unavoidable reference in certain academic and political contexts. On the other hand, its ontological assumptions, epistemological framework, and practical implications, which are the central themes of this work, have been scarce. Our aim is to raise some problems of this perspective -as expressed in our context- and develop its scope. Following these axes, we will apply our considerations on the proposals of Comprehensive Sexual Education (ESI in Spanish). Our contention is that when we focus on the experiences of trans* people, the so-called "gender perspective" is all too often part of the problem to be solved, rather than its solution.

In recent decades grammar teaching has ceased to be one of the main axes that organized the subject Language and Literature (today, Language Practices) in Argentina. According to the Curricular Design of the province of Buenos Aires, grammatical knowledge should remain being systematized in relation to reading, writing and oral practices. In this context, it would be expected that the corresponding textbooks promote this interrelation between grammar and use. In this paper, we aim to analyze how the different combina tions between sentences are presented and explained in these texts from a grammatical perspective, and if they are articulated with the discursive practices. To do this, we carried out a survey of the issue in the last Language Practices textbooks published by Santillana, Kapelusz, Estrada for 3rd year of the secondary education. The investigation showed that there is no clear distinction in these texts between word class, syntactic function and discursive functioning. On the other hand, there was a great terminological variation and lack of specification and consistency in the criteria used to cover both coordination and subordination. Finally, in relation to explanations and activities, there is, essentially, a traditional approach to grammar that does not promote a real connection with the use of language, as proposed in the current curriculum design.

La exposición a una enfermedad potencialmente mortal como el cáncer puede constituir una experiencia traumática que, en algunos casos, puede dar lugar al desarrollo de un trastorno por estrés postraumático (TEPT). En los últimos años, varios estudios han investigado este síndrome en pacientes con cáncer, pero pocos se han centrado en la neurobiología subyacente. El objetivo de este trabajo ha sido revisar la literatura actual de la neurobiología del TEPT en las enfermedades oncológicas, centrándonos en compararla con los resultados de los estudios neurobiológicos sobre el TEPT en pacientes no oncológicos y en los tratamientos que han resultado ser eficaces para dicho trastorno. Las estructuras cerebrales que desempeñan un papel en la aparición del TEPT en psico-oncología, y en particular en los síntomas intrusivos, parecen ser las mismas que están involucradas en el TEPT no oncológico. Estos hallazgos pueden tener implicaciones importantes también a nivel clínico, lo que sugiere que las psicoterapias que resulten ser eficaces para tratar el TEPT en diferentes poblaciones pueden ofrecerse también a pacientes con síntomas postraumáticos inducidos por el cáncer. Se necesitan más estudios para profundizar en nuestros conocimientos sobre la neurobiología del TEPT relacionado con el cáncer y su tratamiento, con el objetivo de transferir los resultados a la práctica clínica.

Nitrogen (N) and sulfur (S) are very important nutrients in corn production in the Pampas Region. However, there is not enough bibliographic evidence related to N and S effects and their interaction on grain yield response, N and S fertilizer use efficiency (EUFN and EUFS) and the economic benefit of fertilizing with N and S. The objective of this work was to evaluate N and S application effects on corn grain yield, EUFN and EUFS, and the fertilization economic return under different environments in the province of Buenos Aires. Two experiments with different N and S rates were conducted at Balcarce (Bce I and Bce II) and two at 9 de Julio (9dJ I and 9dJ II) during 2005-06, 2006-07 and 2007-08. No N-S interactions were found in any studied variable. Nitrogen application increased grain yield (p<0.01) up to 32, 15, 54 y 72% at Bce I, Bce II, 9dJ I and 9dJ II, respectively; whereas S application increased grain yield at Bce II, 9dJ I and 9dJ II (p<0.05) (maximum responses of 11, 10 and 22%, respectively). The EUFN was not systematically affected by S application. The EUFS did not change with increasing S rates, but it improved when N was applied at Bce II and 9dJ I. Fertilization economic return varied but it was favourable at high productivity environments with low soil availability of both nutrients (reaching maximum values of 4.16 $/$ invested in N at 9dJ I and of 18.56 $/$ invested in S at 9dJ II). It is imperative to continue studying N-S interactions in corn in order to adjust fertilizer recommendations. [ABSTRACT FROM AUTHOR]

Nitrogen fertilization in corn under no-till is a common practice in SE Buenos Aires Province; however, there is insufficient local information to define the nitrogen (N) rate that corresponds to the maximum economic benefit. The aim of this work was to optimize the economic nitrogen rate (DOE) for corn under no-tillage using an improved mathematical model and by choosing the best moment for N fertilization. In addition, the effect of N-corn grain price and year potential was compared to the DOE. Data was obtained from 23 N fertilization experiments which took place from 1994 to 2005 and had contrasting environmental conditions (years with different potentiality). Fifteen of these experiments had N applied at planting (SI) and 8 at the six-leaf stage (V6). A statistical criterion to select the best model for defining the DOE was not found; the quadratic-plateau model presented the most conservative results from an agronomic point of view. For the quadratic-plateau model, the year potentiality effect produced variations in the DOE of 59 and 54 kg N ha-1 for SI and V6, respectively; whereas the price relationship effect produced variations of 30 and 23 kg N ha-1 for SI and V6, respectively. In conclusion, the year potentiality affected the DOE more than the N-corn grain price relationship and the six-leaf stage appeared to be the most appropriate moment for N fertilization taking into account economic and environmental aspects.
