A bibliometric analysis of doctoral dissertations in the subdiscipline of audiovisual translation
This work analyses the evolution and current state of the art in audiovisual translation research as portrayed in doctoral dissertations worldwide, which is part of the studies I am conducting for my own PhD thesis at the University of Alicante, Spain. Audiovisual translation studies is still a very young subdiscipline of translation studies, and more research in this field is needed to describe and explain what its authors, institutions, journals, research groups and other actors have done so far, how and why. In this connection, doctoral dissertations usually represent the most comprehensive, cutting-edge investigation projects that researchers face in their careers, and therefore their study brings about abundant information enabling us to provide a portrait of the subdiscipline. That information includes main topics and trends, academic networks of authors, gender differences between authors and supervisors, academic networks, most productive supervisors, universities and countries, most common languages, years of publication or access mode. All this data helps to analyse, delineate and categorise the subdiscipline of audiovisual translation
Influences of Fourier Completely Bounded Polynomials and Classical Simulation of Quantum Algorithms
We give a new presentation of the main result of Arunachalam, Bri\"et and
Palazuelos (SICOMP'19) and show that quantum query algorithms are characterized
by a new class of polynomials which we call Fourier completely bounded
polynomials. We conjecture that all such polynomials have an influential
variable. This conjecture is weaker than the famous Aaronson-Ambainis (AA)
conjecture (Theory of Computing'14), but has the same implications for
classical simulation of quantum query algorithms.
We prove a new case of the AA conjecture by showing that it holds for
homogeneous Fourier completely bounded polynomials. This implies that if the
output of -query quantum algorithm is a homogeneous polynomial of degree
, then it has a variable with influence at least .
In addition, we give an alternative proof of the results of Bansal, Sinha and
de Wolf (CCC'22 and QIP'23) showing that block-multilinear completely bounded
polynomials have influential variables. Our proof is simpler, obtains better
constants and does not use randomness
Membrane synthesis by microemulsion polymerisation stabilised by commercial non-ionic surfactants
Earlier works had demonstrated that microemulsion polymerisation is a well suited technique to produce nanostructured membranes if surfmers (polymerisable surfactants) are used to stabilise the primary template (sponge phase microemulsion). Up to now, however; same hadn't been done using common surfactants. Present work aims to show this is possible if proper surfactants are selected. Specific formulation selection was done by means of phase diagram. Phase diagram was obtained by conductivity, surface tension and QELS measurements through several dilution lines. Polymerisation region was selected from phase diagram were no globular system was observed. Membranes were characterised by SEM, DSC and permeation experiment
The Definition of Damage Resulting from Transboundary Movements of Living Modified Organisms in Light of the Cartagena Protocol on Biosafety
P. 319-342The concept of risk requires preventative measures as well as measures of liability and redress in the case that damage is actually caused. The Cartagena Protocol on Biosafety limits itself in Article 27 to the establishment of a mandate for the elaboration of norms and procedures in regard to liability and redress.
The development of this Article 27 requires firstly a definition of the concept of damage to the conservation and sustainable use of biological diversity, secondly a survey of the extent of damages to health, and the consideration of socioeconomic aspects. With this aim, we will analyse the concept of damage in the international instruments which deal with this material, taking into account levels of implantation.
We will conclude by presenting the definition of damage in the context of the tasks to develop the content of the Article 27 determining an administrative focus as regards the liability of the status and the concept of damage for a civil liability fitting with national rights.
- La idea de riesgo requiere tanto medidas de prevención como de responsabilidad y compensación en el supuesto de que se origine un daño. El Cartagena Protocol on Biosafety se limita a establecer, en su artículo 27, un mandato para la elaboración de unas normas y procedimientos sobre responsabilidad y compensación.
El desarrollo del artículo requiere la delimitación del concepto de damage to the conservation an sustainable use of biological diversity, el estudio de la extensión a los daños a la salud, y la consideración de aspectos socioeconómicos. Con esta finalidad, se analiza la idea de daño en los instrumentos internacionales que abordan esta materia teniendo presente su grado de implantación.
Concluye exponiendo la definición de daño en el marco de los trabajos de desarrollo del artículo 27 determinando un enfoque administrativo sobre la responsabilidad de los Estados y una noción de daño para una responsabilidad civil acorde con los derechos nacionalesS
The interplay between boundary spanning activities and social cohesion in new product development teams
Team boundary spanning represents a team’s actions to establish links and manage interactions with individuals and groups external to the team with the purpose of coordinating activities and accessing information, resources and political support. Research in NPD has shown that team boundary spanning activity positively influences new product performance. Thus, reaching outside the team and interacting with others can provide teams with valuable resources for NPD projects. However, access to external resources cannot guarantee new product performance if these resources are not considered by the NPD team. In this respect, recent work suggests that team-level psychological characteristics such as social cohesion could undermine team members’ motivation to use resources obtained via boundary spanning efforts. In light of the previous discussion, two important research questions arise: 1) Does social cohesion hinder the impact of team boundary spanning on new product performance? Is the relationship between team boundary spanning and social cohesion contingent on the type of task given to the team? The current study examines these two research questions using data from 140 NPD teams.Consideramos como actividades de expansión de fronteras de un equipo las acciones encaminadas a establecer vínculos y dirigir las interacciones con individuos y grupos externos al mismo realizadas con el propósito de coordinar tareas y acceder a información, recursos y apoyo político. La literatura sobre desarrollo de nuevos productos ha mostrado que ir más allá de los límites del propio equipo e interactuar con otros puede proveer al equipo con recursos valiosos para sus proyectos de innovación. Sin embargo, el merco acceso a recursos externos no garantiza el éxito del nuevo producto; los recursos han de ser utilizados. A este respecto, trabajos recientes sugieran que las características psicológicas a nivel equipo, por ejemplo, la cohesión social, pueden minar la motivación de los miembros del equipo para usar los recursos obtenidos a través de la realización de esfuerzos de expansión de fronteras. A la luz de esta consideración, en esta investigación nos planteamos dos cuestiones: ¿puede la cohesión social ocultar el impacto positivo de las actividades de expansión de fronteras en el resultado del nuevo producto? ¿Es la relación entre las actividades de expansión de fronteras y la cohesión social contingente con el tipo de tarea que realiza el equipo? El presente trabajo en curso examina estas dos cuestiones utilizando datos de 140 proyectos de desarrollo de nuevos productos
Niche shifts after long-distance dispersal events in bipolar sedges (Carex, Cyperaceae)
PREMISE OF THE STUDY: Bipolar species represent the greatest biogeographical disjunction on Earth, raising many questions about the colonization and adaptive processes behind such striking distribution. We investigated climatic niche differences of five Carex bipolar species in North and South America to assess niche shifts between these two regions. Moreover, we assessed potential distribution changes with future climate change. METHODS: We used 1202 presence data points from herbarium specimens and 19 bioclimatic variables to assess climatic niche differences and potential distributions among the five species using ordination methods and Maxent. KEY RESULTS: The niche overlap analyses showed low levels of niche filling and high climatic niche expansion between North and South America. Carex macloviana and C. maritima showed the greatest niche expansion (60% and 96%, respectively), followed by C. magellanica (45%) and C. microglochin (39%). Only C. canescens did not colonize new environments (niche expansion = 0.2%). In contrast, all species but C. magellanica had niche filling that was <40%; hence, they are absent in the south from many environments they inhabit in North America. Climate change will push all species toward higher latitudes and elevation, reducing the availability of suitable environments. CONCLUSIONS: The colonization of South America seems to have involved frequent climatic niche shifts. Most species have colonized new environments from those occupied in the North. Observed niche shifts appear congruent with time since colonization and with current genetic structure within species. In these cold-dwelling species, climate change will most likely decrease their suitable environments in the future.Ministerio de Economía y Competitividad CGL2012-3874, CGL2016-77401-
La libertad de los Estados para definir los parámetros de aceptación de la jurisdicción obligatoria de la Corte Internacional de Justicia. La Sentencia de 21 de junio de 2000 en el asunto del incidente aéreo de 10 de agosto de 1999 (Pakistán c. India)
Live Demonstration: Real-time neuro-inspired sound source localization and tracking architecture applied to a robotic platform
This live demonstration presents a sound source
localization and tracking system implemented with Spike Signal
Processing (SSP) building blocks on FPGA devices. The system
architecture is based on the ability of the mammalian auditory
system to locate the direction of a sound in the horizontal plane
using the interaural intensity difference. We used a binaural
Neuromorphic Auditory Sensor to obtain spike rates similar to
those generated by the inner hair cells of the human auditory
system and the component that obtains the interaural intensity
difference is inspired by the lateral superior olive. The spike
stream that represents the interaural intensity difference is used
to turn a robotic platform towards the sound source direction.
The system was tested with pure tones (1-kHz, 2.5-kHz and 5-
kHz sounds) with an average error of 2.32 degrees.Ministerio de Economía y Competitividad TEC2016-77785-
