Other-initiated Repair in Argentine Sign Language

Other-initiated repair is an essential interactional practice to secure mutual understanding in everyday interaction. This article presents evidence from a large conversational corpus of a sign language, showing that signers of Argentine Sign Language (Lengua de Señas Argentina or ‘LSA’), like users of spoken languages, use a systematic set of linguistic formats and practices to indicate troubles of signing, seeing and understanding. The general aim of this article is to provide a general overview of the different visual-gestural linguistic patterns of other-initiated repair sequences in LSA. It also describes the quantitative distribution of other-initiated repair formats based on a collection of 213 cases. It describes the multimodal components of open and restricted types of repair initiators, and reports a previously undescribed implicit practice to initiate repair in LSA in comparison to explicitly produced formats. Part of a special issue presenting repair systems across a range of languages, this article contributes to a better understanding of the phenomenon of other-initiated repair in terms of visual and gestural practices in human interaction in both signed and spoken languages

Suspending the next turn as a form of repair initiation: Evidence from Argentine Sign Language

Practices of other initiated repair deal with problems of hearing or understanding what another person has said in the fast-moving turn-by-turn flow of conversation. As such, other-initiated repair plays a fundamental role in the maintenance of intersubjectivity in social interaction. This study finds and analyses a special type of other initiated repair that is used in turn-by-turn conversation in a sign language: Argentine Sign Language (Lengua de Sehas Argentina or LSA). We describe a type of response termed a "freeze-look,' which occurs when a person has just been asked a direct question: instead of answering the question in the next turn position, the person holds still while looking directly at the questioner. In these cases it is clear that the person is aware of having just been addressed and is not otherwise accounting for their delay in responding (e.g., by displaying a "thinking" face or hesitation, etc.). We find that this behavior functions as a way for an addressee to initiate repair by the person who asked the question. The "freeze-look" results in the questioner "re-doing" their action of asking a question, for example by repeating or rephrasing it Thus, we argue that the "freeze-look" is a practice for other-initiation of repair. In addition, we argue that it is an "off-record" practice, thus contrasting with known on record practices such as saying "Huh?" or equivalents. The findings aim to contribute to research on human understanding in everyday turn-by-turn conversation by looking at an understudied sign language, with possible implications for our understanding of visual bodily communication in spoken languages as we

On the multiplicity of ALMA Compact Array counterparts of far-infrared bright quasars

We present ALMA Atacama Compact Array (ACA) 870 micron continuum maps of 28 infrared-bright SDSS quasars with Herschel/SPIRE detections at redshifts 2-4, the largest such sample ever observed with ALMA. The ACA detections are centred on the SDSS coordinates to within 1 arcsec for about 80 per cent of the sample. Larger offsets indicate that the far-infrared (FIR) emission detected by Herschel might come from a companion source. The majority of the objects (about 70 per cent) have unique ACA counterparts within the SPIRE beam down to 3-4 arcsec resolution. Only 30 per cent of the sample shows clear evidence for multiple sources with secondary counterparts contributing to the total 870 micron flux within the SPIRE beam to at least 25 per cent. We discuss the limitations of the data based on simulated pairs of point-like sources at the resolution of the ACA and present an extensive comparison of our findings with recent works on the multiplicities of sub-millimetre galaxies. We conclude that, despite the coarse resolution of the ACA, our data support the idea that, for a large fraction of FIR-bright quasars, the sub-mm emission comes from single sources. Our results suggest that, on average, optically bright quasars with strong FIR emission are not triggered by early-stage mergers but are, instead, together with their associated star formation rates, the outcome of either late-stage mergers or secular processes.Comment: 16 pages, 10 figure

Renormalization Group Flow of the Holst Action

The renormalization group (RG) properties of quantum gravity are explored, using the vielbein and the spin connection as the fundamental field variables. The scale dependent effective action is required to be invariant both under space time diffeomorphisms and local frame rotations. The nonperturbative RG equation is solved explicitly on the truncated theory space defined by a three parameter family of Holst-type actions which involve a running Immirzi parameter. We find evidence for the existence of an asymptotically safe fundamental theory, probably inequivalent to metric quantum gravity constructed in the same way.Comment: 5 pages, 1 figur

Tierra, fuego, agua y aire: la escultura en Raku

La incorporación al Espacio Europeo de Educación Superior, ha traído consigo cambios metodológicos docentes. Los departamentos de Escultura y Pintura de la Facultad de Bellas Artes no han querido ser ajenos a ellos y desde los mismos varios profesores hemos diseñado y llevado a cabo una actividad docente común centrada en los alumnos a través de la técnica del aprendizaje activo. Estudiantes de tercero, cuarto y quinto curso de licenciatura y grado han ejercitado diferentes competencias profesionales partiendo de un problema común propuesto: el diseño y construcción de un horno artesanal y la ideación y realización de esculturas cociéndolas en el mismo con la técnica del raku. El objetivo no era únicamente la resolución del problema sino que el alumno fuera capaz de adquirir y aplicar todo un conjunto de conocimientos tanto teóricos como prácticos de la disciplina convirtiéndose en protagonista de su propio aprendizaje. Los resultados se plasmaron posteriormente en la exposición de las obras y en la publicación del desarrollo del proceso en el campus virtualPeer Reviewe
