This research aimed to infer the incidence of educational reforms in the generation of new conditions for citizen education in order to be able to raise awareness about characteristics that this educational model has adopted in cases representative of the diversity that the reforms have imprinted upon the third course of Basic General Education (EGB). Specifically, the research focused on the implemented changes and possible resistances to the EGB3 in five schools considered as fields of practice (three in the Province of Entre Ríos and two in the Province of Buenos Aires), through four main analytic lines which allowed us to understand the educational reform as a social regulation process: teaching working conditions, institutions and subjects evaluation, teachers and professors training and educational materials. The reforms were analyzed as Neoliberal and of so-called modernization processes instruments of regulation and, more specifically, the focus was on the consequences that those processes would have in the conformation of new citizen identities by way of the reforms.

The primary objective of this paper is to serve as a comparative basis for other Latin American countries studies that could be considering similar symptoms in the Accounting research area. The starting point is a case study of the faculty members at the Department of Accounting and Finances of the Faculty of Economic and Social Sciences of the University of the Andes. The paper analyzes the relationship between research and teaching and whether the department is fulfilling its goals or not. A secondary objective is to determine the possible factors that have had a significant influence upon the research and teaching performance of the researchers. Using interviews and direct data collection, institutional strategies are considered in order to set the aims of the research activities.

This comparative study attempted to reveal the heterogeneities of urban poverty that frame the life of poor families in two agglomerations of the Province of Entre Ríos: Paraná and Concordia. We considered poverty as a heterogeneous phenomenon, not only by magnitude and intensity but also by configuration, conditioned by the urban environment and the economic and social structures. Over the last decade of the 20th Century and the first years of the 21st C., poverty was enhanced and several structural transformations occurred in Argentina which, undoubtedly, made social inequality worse. They can be summarized in: state reform, privatizations and labor reforms, recessive processes and outsourcing of economy. Description perspectives and methodological analyses are framed within the style of complementarity, in order to achieve a deeper approach to reproduction of poverty and the strategies of poor homes.

The aim of this article is to display a way of questioning a technique for the gathering of information through the analysis of the interaction process of the reflexivities involved (researcher-informant), and at the same time show how fertile it is in the field of local development, because it enables to grasp and interpret social relations and processes. The technique analyzed is the Focal Group. Its application and the constant reflection on its implementation have led us to some considerations, adjustments and reformulations that have driven us away from what has been methodologically prescribed, but which have made it possible for us to make progress in the shaping of a new technique which we think is more adequate for research in the field of local development. We are particularly interested in the development of the construction of the "scene" required for its implementation in the case of research on this subject.

This is a report on the results of a survey about AIDS/STI and sexuality conducted on the population of students starting their first year in college from the 2003 cohort of the National University of Entre Ríos (Argentina). The purpose was to make a diagnosis of their sources of information about sexuality, their knowledge about STI/AIDS, sexual behavior (initiation and prevention practices) and possible attitudes towards persons living with HIV/AIDS. We consider that the identification of the needs of this young population is very important in order to more specifically address to them preventive actions, according to the place where they live and taking into account that the different academic seats of the university are distributed throughout the Entre Ríos Province. The results were compared with the ones from a similar survey applied to newly enrolled students in 1998, looking for changes in knowledge, attitudes and practices.

Myocastor coypus (coypu) is a rodent world-wide used as a skin species. The purpose of the present study was to determine the morphology of the pre-implantation embryonic development in Myocastor coypus (coypu). Thirty-three virgin and sexually mature females allotted in 6 family nuclei and 1 male were utilised. The mating program implied the daily colpocytological examination by using standardised routine techniques. Samples for the colpocytological follow-up were collected from all the animals between 11 and 11:30 hours a.m. The observation of vaginal smears was done directly within 5 minutes of sampling. The controlled mating methodology was used. After the oestrus was established by colpocytology, the female was immediately moved to the male's pen. The embryonic age was determined in days post-coitus (d.p.c.), establishing as day 0 the day when spermatozoa were identified in the vaginal smear. Oocytes and embryos were obtained by flushing from day 0 to 10 post-coitus (p.c.). On day 1 p.c., oocytes predominated whereas on day 2 p.c. zygote were predominant. The cleavage period was from day 3 to day 6 p.c. Morulae were collected from day 6 to 9 p.c., whereas blastocysts were collected in days 8 and 9. From oviduct flushing, embryos in zygote and up to morula with less than 30 cells stage were recovered. Embryos in morula with 30 or more cells and up to blastocyst in growth stage were collected from the flushing of hemiuteri.

Extensive feeding systems produce beef with physical, chemical and nutritive characteristics that show greater differentiation than those obtained by intensive feeding system with a longer confinement finishing period. Highly energetic grain-based diets become particularly interesting in such aspects as fat colour, tenderness, lipidic insaturation and growth rate. However, potential problems like organoleptic alterations, reduction of shelf life, lower concentration of conjugated linoleic acid and a higher relation of fatty acids n6/n3 should also be taken into consideration. In addition, none or inadequate application of technological procedures by the meat industry can lead to the deterioration and increase in variability of those attributes most valued in the market. Information concerning the type of beef being purchased as well as the ways of preparation should be available in order to guarantee consumer satisfaction.

Functional neuromuscular stimulation (FNS) is a rehabilitation technique which can be applied to people with motor control difficulties and it is employed to replace or assist a loosed o diminished motor function. It consists on the excitation of the healthy peripherical innervations by means of electrical pulses to perform muscular contraction. Systems that employ FNS have a constant current source at the output. These systems may be multichannel systems and they activate different motor groups through the application of active electrodes and only one indifferent electrode. This issue requires particular characteristics for the current sources. In this article we present the design of a constant current source to be employed at the output of FNS systems which give monophasic and biphasic stimulation pulses and their outputs maintain high impedance mine while they are not active. Results show that the current was constant facing variations in the output impedance and it presented a lineal relationship between the control input and current output. The design also gives the possibility of having biphasic pulses of different conformation at the output.

In the socio-economic and technological evolution of the agroecosystems of the pampean region in the last 30 years three productive models can be recognized: the agriculturization model, an intermediate one characterized by the launch of no till modality and transgenic soybean (RR gene), and the current model with high potential yield crops, consolidation of the no till system as well as the increasing use of agrochemicals. These technological models induced modifications in the agroecosystems feasible of being analyzed through energetic parameters, due to the tight association between the energy consumption, the agroecosystems productivity and the intensification of agriculture. Since 1970 there was a rise in the amount of energy employed by the agroecosystems, while the energetic efficiency remained high owed to the increase in the registered yields. Wheat turned out to be the least energetically efficient crop. The present technological model results in the highest labour yield.

This paper presents a brief review about the characteristics of the plants cuticle and its relationship with herbicide penetration as well as about the factors affecting that penetration. Structural aspects like waxes cuticle and environmental characteristics that determine the correct absorption of the herbicide were taken into account. References to a study carried out on Eryngium horridum, the presence of stomata and the differential penetration of the herbicides in sheaf and back of the leaves were done.
