Cow-calf systems are at the core of Argentina´s significant national beef industry. The objectives were: i) to characterize the productive state of traditional cow-calf systems, named BASE, from the northern region of Santa Fe province, ii) to identify technologies for the productive improvement of the BASE system, and iii) to quantify the productive and economic impact of the adoption of the identified technologies. To characterize the BASE system, the available published data were systematized and validated in a workshop with leading regional experts in the field. To identify the technologies for improvement, a survey was conducted among regional farm advisors. Finally, to quantify the impact of adopting improvements in the BASE system, a modelling study was conducted. The results showed that traditional cow-calf systems have low productive and reproductive efficiency (45 kg LW ha-1 year-1 and 48% weaning rate) and little adoption of herd management and forage production technologies. The technologies identified were grazing management, training of farmers and farm staff, and seasonal mating. The modelling study showed that improvements in the production and use of forage and herd management practices would increase beef production and the gross margin of the BASE system by 70% and 96%, respectively.

Information technologies have been part of local government for decades, albeit with different characteristics and scope depending on the case. This was particularly evident in the Covid-19 pandemic. This article asks about the characteristicsof digitization in force in Argentine local governments. and the divergent profiles that can be identified in this regard. It is oriented to the development of strategies to strengthen digitization. The source of information are the results of the project "State capacities in a post-pandemic municipal agenda", directed by Dr. Patricia Nari, The paper begins with the conceptual presentation of management digitization, then describes the most relevant elements of the work methodology, presents the results of the field work and finally describes the digitization profiles of local governments and discusses the theoretical and methodological model constructed.

Introduction: In this study, the categories "paper reading", "screen reading" and "ways of reading" were analyzed through the words of teachers who belong to different disciplines and headquarters of the Universidad Nacional del Comahue (UNCo), Patagonia, Argentina. Method: For this study, part of a major investigation carried out within the framework of a doctoral thesis in Education, the constant comparative method was used, and qualitative data from semi-structured interviews with teachers, conducted during the 2014-2017 period, were analyzed. Objective: The main objective was to determine the representations of UNCo lectures regarding screen reading and their relationship with the task of teaching at university. Results: Concerning results, on the one hand, it was observed that the ratings on screen reading were different when the focus was shifted from the task of teaching to research. On the other hand, there were several changes in the ways of reading and teaching, although it was admitted that these do not always lead to profound transformations in education. Conclusion: The main conclusion was that, in certain situations, it seems that the so-called "new" technologies have demolished several walls, allowing for more extensive and open ways of teaching, but at the same time, it is noted that new walls have been erected, some of which only reproduce old pedagogical models.

We present the results about the last researches carried out on ceramic fabrics of Las Garzas, an Early site (600 a.C.-650 d.C.) located in the Lerma Valley (Province of Salta, Argentina). This approach implied a revision of previous studies initiated by Cremonte (Cremonte et al., 1987), which allowed us to adjust the petrography of the ceramic pastes, expanding the analyzed sample and completing the previous analyzes incorporating different recording procedures. Data obtained in relation to the local geology allowed us to hypothesize about foreign or in situ production of the vessels represented in the studied sample. Likewise, comparisons with other pottery groups from the Lerma Valley and more distant pottery traditions such as Tafí and San Francisco valleys, allowed us to evaluate links in the manufacturing techniques that contribute to our knowledge about early pottery technological traditions in Northwestern Argentina.

This article presents some results of a research on processes of transformation of pedagogic devices in the context of the introduction of information and communication technologies (ICT) in our society. Field work was carried out in State secondary schools in the Metropolitan area of Buenos Aires (Argentina). We understand that ICT have effects on the ways we think and act in the world, and in the processes of subjectivity production with regard to the material and symbolic transformation of our daily lives and that of the institutions. Schools have not been left out: they are questioned by the shapes that production, distribution and access to culture have taken. Through the "episodes analysis", we aim to describe the ways in which the informatization processes are expressed within the school. The question, "Is there a hypertext in this class?" is answered through the description of some dynamics that characterize the pedagogic devices in digital and postalphabetic times.

The article considers the construction of identity in two groups of Argentine youth, the so called chetos and cumbieros. It focuses on their discursive practices, clothing styles and relationship with the consumption of various goods, particularly communication technology. In this context, certain products appear to cross social class barriers and have become universal products the consumption of which generates a sense of belonging. [TRANSLATION]
