Manos al lenguaje

The aim of this paper is to discuss through the study of language several onto-logical and epistemological issues related to human mind from the standpoint of "biological functionalism". First of all, I try to make clear the sense in which the term "function" is used in evolutionary biology. Then, I consider some aspects of human language: its neuronal basis, its evolution, its connections with other features which are proper of hominids--specially the manipulation of objects--and finally, its function in the configuration of human mind

Contemporary Art Therapists: Study of Identity Within Artmaking

This paper highlights the design and results of a research study conducted by graduate art therapy students that surveyed professional art therapists and the role that personal and clinical art making has in their practice. The study included a mixed-method approach that involved a survey of 88 graduates from art therapy programs, interviews, the creation of art by art therapists, and the creation of art responses by the graduate researchers. The researchers analyzed the data from the surveys and interviews through thematic coding and identified common themes that reflected the research questions: What is the relationship between personal art making and the development of the art therapist and What supports and barriers exist for art therapists to engage in an active art practice within and outside of clinical practice? The themes reflected the importance of having a personal art practice as an art therapist, the relationship between personal work and its impact with clients, the challenge of advocating for the understanding and inclusion of art therapy in professional spaces, and the career long evolution of the relationship between the artist and art therapist identity. These findings emphasize the barriers and supports associated with the art therapist identity

Citizen Archaeologists. Online Collaborative Research about the Human Past

Archaeology has a long tradition of volunteer involvement but also faces considerable challenges in protecting and understanding a geographically widespread, rapidly dwindling and ever threatened cultural resource. This paper considers a newly launched, multi-application crowdsourcing project called MicroPasts that enables both community-led and massive online contributions to high quality research in archaeology, history and heritage. We reflect on preliminary results from this initiative with a focus on the technical challenges, quality control issues and contributors motivations

Genome-wide mapping reveals conserved and diverged R-loop activities in the unusual genetic landscape of the African trypanosome genome

R-loops are stable RNA–DNA hybrids that have been implicated in transcription initiation and termination, as well as in telomere maintenance, chromatin formation, and genome replication and instability. RNA Polymerase (Pol) II transcription in the protozoan parasite Trypanosoma brucei is highly unusual: virtually all genes are co-transcribed from multigene transcription units, with mRNAs generated by linked trans-splicing and polyadenylation, and transcription initiation sites display no conserved promoter motifs. Here, we describe the genome-wide distribution of R-loops in wild type mammal-infective T. brucei and in mutants lacking RNase H1, revealing both conserved and diverged functions. Conserved localization was found at centromeres, rRNA genes and retrotransposon-associated genes. RNA Pol II transcription initiation sites also displayed R-loops, suggesting a broadly conserved role despite the lack of promoter conservation or transcription initiation regulation. However, the most abundant sites of R-loop enrichment were within the regions between coding sequences of the multigene transcription units, where the hybrids coincide with sites of polyadenylation and nucleosome-depletion. Thus, instead of functioning in transcription termination the most widespread localization of R-loops in T. brucei suggests a novel correlation with pre-mRNA processing. Finally, we find little evidence for correlation between R-loop localization and mapped sites of DNA replication initiation
