As a result of theoretical and methodological considerations and empirical research, I present in this paper the general outlines for a relational analysis of studies on poverty, which I consider a rich perspective as far as they make possible the construction of tools suitable to approach the problem from all its dimensions, and specially within the context of reproduction of the society as a whole and of its mechanisms of domination. From the concept of social reproduction strategies, I postulate its relational character in all its aspects, and while emphasizing the resources of poverty, in special the social capital, I point out the analytical potentialities of each one of the above mentioned categories in order to give account of the problem.

This paper presents considerations on urban poverty as a problem exhibiting a new characterization and posing under questioning the modalities of public policies intended to solve those situations. In that direction, we consider that work is one of the medullar topics and that it should be studied in order to produce theoretical considerations about the characteristics of poverty due to low income in developing economies. Our analysis focused in the job market in Concordia City, which is considered as one of the Argentine urban agglomerates with a more significant incidence of poverty. Several proposals for public policies aimed to overcome the problem are derived from that case study.

Technological risk notion is frequently used to question impacts that new technologies -in particular, modern biotechnology- would have on environment, human health and socio-economic dynamics. This paper's purpose is to analyze social movements attitude against these technologies from their speech on technological risk. With such aim we analyze the differents arguments employed by them, introducing the problem from the perspective of "risk society" as well. Finally, we suggest an interpretation on the representation of technology included in risk discourse, accenting its polisemic and fetichist character.

This paper deals with a Small Business Enterprise (PyME) owned by Argentinian investors, established in the middle of the1980s as a Spin Off company producing legume inoculants, a microbiological supply in soy production. The company controls biotechnological processes enrolled within classical biotechnology. The study focused on the company and its learning process in pursue of capturing, adapting and transferring technology, considering its feedback with science and technology public agencies as an important factor. The company faces two realities: the dynamics of its chain production that has lead it to confront with international technological compliances, and the complex and uncertain internal reality. It is particularly interesting to analyze the developing of its dynamic capabilities as well as its strategy to be a leader within the local market and to gain an important share of the regional market while maintaining its competitive level with respect to international producers of legume inoculants.

This paper presents a study lead on the ways in which knowledge relations take shape, such as authorization practices. Accounts were analyzed about students' formation experiences in the careers of Education and Social Communication, to consider the authorized/acknowledged figures in academic discourse and the way in which subjects recognize and constitute themselves in relation to that regime, as well as the manners of authorization that disturb that configuration, setting up discontinuities in the discursive "workings" in which they move about. In the treatment of these two aspects, we have placed ourselves at a distance from those viewpoints which intend to search for indicators to "objectivate" in binary terms the "variables" that determine the conditions of authorization, fixing relations and identities; such "binarisms" operate excluding the event-experience that can be perceived in the students' texts, as particular features that set up a subjective timing in knowledge relation, and allow for the idea of a policy of selfauthorization which brings formation -as a programme- into tension.

The effect of a biodegradable coating, formulated from a natural terpen of vegetable origin, as an alternative to preserve citrus fruit during post-harvest was studied. Two assays were carried out with the following objectives: evaluation of protective effect of the terpenic coating under controlled storing conditions and selection of the most convenient application method for fruit coating. In the fist test, Valencia late oranges, harvest 2003 -2004, were used and analyzed parameters were: dehydration percentage, deformation percentage, maturity index and global acceptance. In the second test, Washington Navel oranges, harvest 2005 and 2006, were employed and the methods were: immersion, manual crushing and standard application. Analyzed variables were: dehydration percentage, deformation percentage and internal quality. Results showed that the terpene coating applied by manual crushing on oranges could have a beneficial effect on postharvest preservation.

This article presents the results of soybean implantation when microorganisms were incorporated during the sowing period and under field conditions. The microorganisms evaluated were three isolates of Trichoderma sp, three isolates of Bacillus and one isolate of Gliocladium roseum. A treatment with fungicide and an untreated plot were incorporated and therefore nine treatments were performed. The effects were evaluated by registering the number of emerging plantlets and the number of plants at harvest, measuring the height of plants, registering the yield components and the plot weight. In average, plots treated with Trichoderma (HT3) emerged in a higher extension. Important interaction between the treatments and the assays was shown. The treatment with Trichoderma (HT3) obtained greater number of plants that reached the harvest stage. Among the Bacillus, B8 isolation showed a good behaviour in two of the tests.

The photosynthetically active radiation (PAR) is important as energy input in diverse biological processes and its temporal evaluation has particular interest in crops monitoring. The data of spectral reflectance, obtained through remote sensors, are useful to provide observations of phenomena that are related to ecophysiological aspects of vegetal covers, including the net primary productivity (NPP). This one constitutes one of the few sources of information about the processes of the cycle of carbon in regional or global scales. The NPP is related to the efficiency of the use of light through the absorbed photosynthetically active radiation (APAR) and represents a useful agroecology indicator to value the productive use of the territory. The objective of this work is to present a methodological contribution to the agroecology through the characterization of the NPP and the APAR, in three geographic and productive situations in the Humid Pampa, Argentina.
