This article analyzes the transformation of the Do It Yourself (DIY) movement from its countercultural origins to its current role as a normative imperative on digital platforms. Drawing on the concept of deep mediatization (Hepp, 2022), this article examines how social media has transformed a practice rooted in autonomy into a mechanism of homogenization.The study draws on surveillance capitalism (Zuboff, 2020), the information regime (Han, 2022), and techno-feudalism (Durand, 2021) to show how algorithms and repetition dynamics on digital platforms actively shape behaviors while creating the illusion of freedom and empowerment. It argues that, paradoxically, what began as resistance has been transformed into an effective system of social control disguised as entertainment and practical solutions.

The increasing datafication and the involuntary generation of data –simply by interacting, with varying degrees of awareness, with a wide range of digital social platforms– calls for a reassessment of the concept of User-Generated Content (UGC). In this regard, the notion of User-Generated Data (UGD) is proposed, based on an idea that is frequently invoked but rarely discussed in academic literature. The discussion focuses on how users’ digital traces are captured and processed by third parties. A critical analysis is then offered, distinguishing and delineating the concepts of UGD and the definition of UGC, arguing that they represent two distinct research strands from which online content generation can be approached.

Interview with Tiziana Terranova.

In this essay, we propose to connect advertising work to the theory of platformization. We analyze advertising work, a living organism within the field of advertising that adapts to the constant updates of phenomena arising from the technological landscape, and associate it with the three dimensions of platformization: data infrastructure, multilateral markets, and governance, which act as methodological operators. First, we conduct a literature review on the concepts addressed here, and then we present the three dimensions of platformization as theoretical-methodological operators, defined as follows: a) Development of data infrastructure applied to advertising activities; b) Reorganization of advertising practices and professional habitus through multilateral markets; and c) Updates in the roles of advertising agents through governance. This essay contributes to the field of communication with a methodological framework that enables a critical analysis of the transformations induced by platformization in advertising work.

The article reflects on and proposes a theoretical discussion about the concept of Underground, one of the media systems operating in contemporary society, as observed by Carlón (2022). In order to reflect on the theoretical and epistemological foundations of this concept, the discussion focuses on the aspects related to the coup events of January 8, 2023, in Brazil. The communicational complexities of this context are critically analyzed through the lens of mediatization, hypermediatization and the structural dimensions of media systems. This analysis allows for inferences about the impact of these communicative dynamics on meaning-making collectives.

The increasing urbanization of the coastal strip and the lack of adequate wastewater treatment or sanitation have led to an increase in the load of fecal contaminants in the waters flowing into recreational beaches, putting the health of beachgoers at risk. Water quality monitoring assesses the abundance of microorganisms of intestinal origin, and the regulations establishing indicators, maximum allowable values (MPVs), and sampling methods vary among countries and regions. The objective of this paper is to provide input for the review of current regulations and recommendations for the management of this contamination in Uruguay. To this end, a bibliographic review of national (historic revision), regional (11 countries), and international (OMS, EPA) regulations regarding fecal contamination in recreational beaches (freshwater and marine) was conducted. Internationally, a variety of indicators are used to assess beach quality, with enterococci and Escherichia coli abundance being the most commonly used in the northern hemisphere, and fecal coliforms at regional and national level. Uruguayan regulations have not been updated for more than 45 years. They are the oldest regulations on the continent and one of the most permissive regarding fecal contamination. Therefore, wesuggest updating Uruguay’s regulations, maintaining the current indicators, adding others such as E. coli and  enterococci and decreasing their MPVs in order to preserve ecosystem health and protect the health of the population.

This work aimed to develop a malt-barley and malta-quinoa craft beer with dehydrated fruit and evaluate the physicochemical properties. Ten treatments (barley-quinoa) of beer were carried out and analyzed; the different treatments were analyzed for color, anthocyanins, pH, total titratable acidity (ATT), volatile acidity, alcohol and density. In color, results were obtained for L* (luminosity) from 25.26 to 39.84, a* (red-green) from 1.85 to 7.11 and b* (blue-yellow) from 9.38 to 15.76. The anthocyanin content was 8.81 to 17.14 mg of cyanidin 3-glucoside/L. The pH was statistically the same (p ≤ 0.05) in all treatments. The alcohol content reached up to 7.13 % v/v. The craft beer is  acceptable because adding quinoa malt and dehydrated blackberry did not affect the quality of anthocyanins, total titratable acidity, pH, alcohol content and volatile acidity of the craft beer. 

This study assessed the impact of sucrose and trehalose as osmotic agents on the quality of freeze-dried starfruit snacks, with particular emphasis on sensory and textural attributes. Starfruit slices were subjected to three pre-treatments before freeze-drying: a control (no dehydration agent), osmotic dehydration in a sucrose solution (ODSAC), and osmotic dehydration in a trehalose solution (ODTRE). The resulting dehydrated samples were analyzed for water activity (aw), instrumental color and texture, and sensory attributes, including consumer acceptability. Both osmotic treatments significantly altered the instrumental texture of the starfruit slices compared to the control. Sensory analysis revealed significant differences in appearance, texture, flavor, and odor among treatments, with the ODTRE treatment receiving the highest acceptability scores. These findings suggest that using trehalose as an osmotic agent enhances the quality attributes of the dehydrated starfruit slices, supporting their potential as a fruit snack option.

This work presents the validation of a methodology for estimating the biovolume at the cellular and filamentous organization level of phytoplankton in the Salto Grande reservoir. The relevance of this study lies in its ability to generate reliable data in the field of ecology, supporting critical decisions in environmental management, while aligning with international and local regulations on water quality monitoring. An effort was made to integrate methodological quality assurance with ecological and health research, coinciding with criteria established by regulations such as the European Commission (2000) and the UNE 14996:2007 standard (Asociación Española de Normalización y Certificación, 2007), which contribute to the proper management of water resources. The main objective of this study was to accurately assess the ecological and health risks associated with bloom-forming organisms identified in the reservoir that impact the use of recreational areas. The results indicate that the validated analytical method presents a high degree of reproducibility and precision, both with values less than 10 %, essential characteristics for any technique aspiring to be used in environmental monitoring.
