    Abstract Resumen Este artículo tiene como objetivo dar cuenta de la relación compleja entre el niño problemático y la mujer como cuidadora y responsable, así como la relación entre las nociones de niño problemático y el cuadro del Trastorno de Déficit Atencionales, desde una perspectiva discursiva crítica. Para ello se revisaron discursos relacionados al niño problema que las disciplinas Psi desarrollaron en una revista femenina de alta circulación en Chile, durante los años 1983 y 1989. Entre los resultados se encuentran cómo mujeres y niños quedan del lado de la dominación y subalternidad de lo adulto masculino y las disciplinas Psi, donde los cuerpos disciplinados toman un lugar preponderante. Se finaliza con una hipótesis acerca del rol protector del diagnóstico psi en el entorno violento de la dictadura.

    Abstract Histone H1, a vital component in chromatin structure, binds to linker DNA and regulates nuclear processes. We have investigated the distribution of histone H1 variants in a breast cancer cell line using ChIP-Seq. Two major groups of variants are identified: H1.2, H1.3, H1.5 and H1.0 are abundant in low GC regions (B compartment), while H1.4 and H1X preferentially localize in high GC regions (A compartment). Examining their abundance within transposable elements (TEs) reveals that H1X and H1.4 are enriched in recently-incorporated TEs (SVA and SINE-Alu), while H1.0/H1.2/H1.3/H1.5 are more abundant in older elements. Notably, H1X is particularly enriched in SVA families, while H1.4 shows the highest abundance in young AluY elements. Although low GC variants are generally enriched in LINE, LTR and DNA repeats, H1X and H1.4 are also abundant in a subset of recent LINE-L1 and LTR repeats. H1X enrichment at SVA and Alu is consistent across multiple cell lines. Further, H1X depletion leads to TE derepression, suggesting its role in maintaining TE repression. Overall, this study provides novel insights into the differential distribution of histone H1 variants among repetitive elements, highlighting the potential involvement of H1X in repressing TEs recently incorporated within the human genome.

    Abstract Histone H1 participates in chromatin condensation and regulates nuclear processes. Human somatic cells may contain up to seven histone H1 variants, although their functional heterogeneity is not fully understood. Here, we have profiled the differential nuclear distribution of the somatic H1 repertoire in human cells through imaging techniques including super-resolution microscopy. H1 variants exhibit characteristic distribution patterns in both interphase and mitosis. H1.2, H1.3, and H1.5 are universally enriched at the nuclear periphery in all cell lines analyzed and co-localize with compacted DNA. H1.0 shows a less pronounced peripheral localization, with apparent variability among different cell lines. On the other hand, H1.4 and H1X are distributed throughout the nucleus, being H1X universally enriched in high-GC regions and abundant in the nucleoli. Interestingly, H1.4 and H1.0 show a more peripheral distribution in cell lines lacking H1.3 and H1.5. The differential distribution patterns of H1 suggest specific functionalities in organizing lamina-associated domains or nucleolar activity, which is further supported by a distinct response of H1X or phosphorylated H1.4 to the inhibition of ribosomal DNA transcription. Moreover, H1 variants depletion affects chromatin structure in a variant-specific manner. Concretely, H1.2 knock-down, either alone or combined, triggers a global chromatin decompaction. Overall, imaging has allowed us to distinguish H1 variants distribution beyond the segregation in two groups denoted by previous ChIP-Seq determinations. Our results support H1 variants heterogeneity and suggest that variant-specific functionality can be shared between different cell types.

    Abstract Forward osmosis (FO) has attracted special attention in water and wastewater treatment due to its role in addressing the challenges of water scarcity and contamination. The presence of emerging contaminants in water sources raises concerns regarding their environmental and public health impacts. Conventional wastewater treatment methods cannot effectively remove these contaminants; thus, innovative approaches are required. FO membranes offer a promising solution for wastewater treatment and removal of the contaminants in wastewater. Several factors influence the performance of FO processes, including concentration polarization, membrane fouling, draw solute selection, and reverse salt flux. Therefore, understanding and optimizing these factors are crucial aspects for improving the efficiency and sustainability of the FO process. This review stresses the need for research to explore the potential and challenges of FO membranes to meet municipal wastewater treatment requirements, to optimize the process, to reduce energy consumption, and to promote scalability for potential industrial applications. In conclusion, FO shows promising performance for wastewater treatment, dealing with emerging pollutants and contributing to sustainable practices. By improving the FO process and addressing its challenges, we could contribute to improve the availability of water resources amid the global water scarcity concerns, as well as contribute to the circular economy.

    Abstract Frequency analysis has been the most widely used tool worldwide to dimension water-related infrastructures and evaluate flood risks. The concept of stationarity has been a common and practical hypothesis in hydrology for many years. However, in recent decades due to climate change pressure and changes in land use, it has been related to the presence of time-series trends that in hydrology indicate non-stationary effects. In this sense, the need to comprehensively address non-stationary frequency analysis has been identified. This study proposes to incorporate the non-stationary flood frequency analysis into the dimensioning process of road structures with the following objectives:

    Abstract Frequency analysis has been the most widely used tool worldwide to dimension water-related infrastructures and evaluate flood risks. The concept of stationarity has been a common and practical hypothesis in hydrology for many years. However, in recent decades due to climate change pressure and changes in land use, it has been related to the presence of time-series trends that in hydrology indicate non-stationary effects. In this sense, the need to comprehensively address non-stationary frequency analysis has been identified. This study proposes to incorporate the non-stationary flood frequency analysis into the dimensioning process of road structures with the following objectives: i) evaluate the effect of land use on peak flow in a simulated period of 129 years, ii) evaluate covariates related to land use, and iii) evaluate covariates related to climate change. To this end, road drainage simulation exercises were carried out in three sections of the Ibagué-Cajamarca road located in Colombia. Likewise, the Generalized Additive Models for Location, Scale and Shape was implemented for the non-stationary analysis, and covariates related to climate variability were included, such as El Niño-Southern Oscillation indices (ONI12, ONI3.4, MEI, and SOI), and the Pacific Decadal Oscillation (PDO) index, as well as some related to the evolution of land use such as hydraulic conductivity, soil water storage in the root zone, and infiltration capacity represented in the curve number. The results indicate that the non-stationary analysis improves the prediction of maximum flows, and it is possible to obtain road drainage dimensioning that adjusts to climate and land-use variations.

    Abstract This case study presents a study in the field of education with children from a socially vulnerable sector of Santiago, Chile. My specific research interest was the discourses that children express about their learning experience. I consider the learning process to be a socially situated phenomenon rather than an individual and generic one. Some of the characteristics of participatory action research in school are outlined, taking into account the Latin American context as well as the challenges research with children presents. In addition, I describe some of the moments in the investigation that posed problematic situations or "diversions," some of them circumstantial and others more theoretical and political that resulted in rethinking the research process at various levels. I conclude with some thoughts about the anticipated and unanticipated effects of this kind of research.

    Abstract Background: The Canary Islands are an archipelago of volcanic origin, located off north-west Africa comprising eight islands. Fuerteventura and Lanzarote are the oldest (20 and 15 millon years old, respectively) and the easternmost islands. The order Diptera is one of the most relevant taxa in the Canary Islands as they constitute the second highest species richness. Within this order, the family Tachinidae is especially interesting as all species are endoparasitoids of arthropods and most species play a key role as pollinators. In the Canary Islands, the family comprises 52 species, with Fuerteventura and Lanzarote harbouring up to 20 species each.
