Spatially explicit estimates of stock size, structure and biomass of North Atlantic albacore tuna (Thunnus alalunga) in the North Atlantic for the period 1956-2010, compiled from the International Commission for the Conservation of Atlantic Tunas

The development of the ecosystem approach and models for the management of ocean marine resources requires easy access to standard validated datasets of historical catch data for the main exploited species. They are used to measure the impact of biomass removal by fisheries and to evaluate the models skills, while the use of standard dataset facilitates models inter-comparison. North Atlantic albacore tuna is exploited all year round by longline and in summer and autumn by surface fisheries and fishery statistics compiled by the International Commission for the Conservation of Atlantic Tunas (ICCAT). Catch and effort with geographical coordinates at monthly spatial resolution of 1° or 5° squares were extracted for this species with a careful definition of fisheries and data screening. In total, thirteen fisheries were defined for the period 1956-2010, with fishing gears longline, troll, mid-water trawl and bait fishing. However, the spatialized catch effort data available in ICCAT database represent a fraction of the entire total catch. Length frequencies of catch were also extracted according to the definition of fisheries above for the period 1956-2010 with a quarterly temporal resolution and spatial resolutions varying from 1°x 1° to 10°x 20°. The resolution used to measure the fish also varies with size-bins of 1, 2 or 5 cm (Fork Length). The screening of data allowed detecting inconsistencies with a relatively large number of samples larger than 150 cm while all studies on the growth of albacore suggest that fish rarely grow up over 130 cm. Therefore, a threshold value of 130 cm has been arbitrarily fixed and all length frequency data above this value removed from the original data set.

The production effect: the role of attentional resources

The production effect is the benefit in memory found for produced (i.e., read aloud) words relative to words read silently. It is proposed that the production effect occurs as a result of the enhanced distinctiveness associated with the produced items. The current research investigated whether attentional resources are required to encode and/or retrieve the distinctive information associated with the produced words. The literature suggests that the encoding of this distinctive information occurs automatically, but at test, purposeful attention is required to retrieve this distinctive information. To test this, participants read words aloud and silently, under either full or divided attention. Participants then completed either a recognition (Experiment 1) or free recall (Experiment 2) memory test under either full or divided attention. The findings show that when attention is divided at encoding, the benefit for aloud words remains for both recognition and free recall. When attention is divided at test, however, the benefit for aloud words remains for recognition but is absent for free recall. Overall, these results suggest that the distinctive information associated with produced words is encoded automatically, but it may not be accessible at test under attentionally demanding conditions.

A noção de relação na teoria linguística de Ferdinand de Saussure

Our work aims at investigating the notion of relation in Ferdinand de Saussure’s linguistic reflections. As we observe his theoretical production, we see this notion was amply worked in the elaboration of other concepts of his, for example, language, signe, value, arbitrariness, among others. However, beyond the capacity of the notion of relation to produce other concepts, the way it was conceived and the theoretical space it was placed allowed Saussure to break through the essentially historical-comparative studies of the epoch, what made a new way of thinking language to have its starting point. Taking it into account, firstly, by reading the work of Herman Paul, the one who represents the neogrammarians in our text, we examine in which way Saussure is distant from his contemporary linguistics when he distinguishes the linguistic relations and give them a new status in his investigation. Secondly, we study how the notion of relation has it own place in Saussure’s theoretical process of thinking the fundamentals which later would be considered the milestone for Modern Linguistics. For that, we analyse one of his manuscripts, Notes pour un livre sur la linguistique générale, and the Course in General Linguistics. The first is composed by sketches which would become a book, as Saussure promised in a letter to Meillet; and the latter contains the principals for the science of Linguistics. So we aim at researching how the notion of relation is treated in this corpus in order to see the way it is conceived both in the particular production of a manuscript written by Saussure itself and the book which was published and considered the turning point for Linguistics.

Asymmetric 3D video coding based on regions of perceptual relevance

This dissertation presents a study and experimental research on asymmetric coding of stereoscopic video. A review on 3D technologies, video formats and coding is rst presented and then particular emphasis is given to asymmetric coding of 3D content and performance evaluation methods, based on subjective measures, of methods using asymmetric coding. The research objective was de ned to be an extension of the current concept of asymmetric coding for stereo video. To achieve this objective the rst step consists in de ning regions in the spatial dimension of auxiliary view with di erent perceptual relevance within the stereo pair, which are identi ed by a binary mask. Then these regions are encoded with better quality (lower quantisation) for the most relevant ones and worse quality (higher quantisation) for the those with lower perceptual relevance. The actual estimation of the relevance of a given region is based on a measure of disparity according to the absolute di erence between views. To allow encoding of a stereo sequence using this method, a reference H.264/MVC encoder (JM) has been modi ed to allow additional con guration parameters and inputs. The nal encoder is still standard compliant. In order to show the viability of the method subjective assessment tests were performed over a wide range of objective qualities of the auxiliary view. The results of these tests allow us to prove 3 main goals. First, it is shown that the proposed method can be more e cient than traditional asymmetric coding when encoding stereo video at higher qualities/rates. The method can also be used to extend the threshold at which uniform asymmetric coding methods start to have an impact on the subjective quality perceived by the observers. Finally the issue of eye dominance is addressed. Results from stereo still images displayed over a short period of time showed it has little or no impact on the proposed method.

Biomass of large protists from the Infrakingdom Rhizaria in the global ocean

The present data set is a worldwide compilation from 11 oceanographic expeditions during which an underwater vision profiler (UVP) was deployed in situ to determine the vertical distribution (biomass) of 4 taxonomic groups of plankton larger than 600 µm, belonging to the Infrakingdom Rhizaria, including Collodaria, Acantharia, Phaeodaria and other Rhizaria. Vertical distributions are binned in four layers: 0-100, 0-200, 100-500 and 0-500 m.

Enigmas monetarios en el derecho local. Los mencales y maravedís en los fueros castellanos

La historia de la moneda en la Castilla medieval ha estado siempre mediatizada por la convivencia no siempre armónica entre dos sistemas monetarios muy diferentes. Uno basado en la plata, de origen europeo, otro centrado en el oro, de raíces árabes. La necesidad de conectar y de establecer unas equivalencias entre ellos se convirtió pronto en una necesidad, máxime cuando las monedas de oro incrementaron sus variantes. En esta compleja situación aparecen mencales y maravedís citados conjuntamente en muchos fueros: Zorita, Uclés, Cuenca,... sin que su naturaleza quede del todo clara. Este artículo compara estas referencias y analiza las equivalencias que los unen. Como colofón al trabajo podemos afirmar que los maravedís citados en cada texto corresponden a monedas áureas de distinto peso y valor mientras el mencal es identificado con un ponderal de oro que los relaciona.

La gárgola en la cultura visual actual

La gárgola ha poblado desde antiguo las cornisas de los edificios religiosos y civiles, sirviendo de evacuación para el agua y para diferentes misiones según las distintas interpretaciones. Su gran componente simbólico hace de ella un reclamo muy interesante para el mundo audiovisual actual. De entre las manifestaciones encontradas, estudiaremos la visión de la gárgola en estos medios y valoraremos su adecuación o no a la visión medieval. Mediante la aparición de la gárgola medieval en el mundo actual en forma de personajes y ornamentos, y gracias a la aplicación de imágenes actuales a las nuevas gárgolas, podemos realizar un recorrido visual y simbólico alrededor de las distintas visiones que la cultura actual realiza de ellas. Pero no podemos quedarnos ahí, es necesario relacionar estas nuevas visiones y significaciones con las originales, para establecer si se ha hecho un uso correcto de la imagen, o se ha roto la estructura del símbolo primigenio.

Fronteras en construcción: Diferenciación social y desterritorialización en el Sur ibérico (siglos IX-VI a.C.)

Durante las tres últimas décadas, numerosos/as arqueólogos/as han discutido extensamente sobre el ritual funerario original de las poblaciones del sur ibérico entre los siglos ix y vi a.c., esto es, cremación o inhumación. Este debate está además conectado con la existencia o no de complejidad social antes de la llegada fenicia, con la aparición de una élite “orientalizada” y con la adopción de nuevos objetos y prácticas por las poblaciones locales. En este artículo hago uso del concepto deleuziano de “desterritorialización” y lo asocio con el de “frontera” desarrollado por anzaldúa para interpretar la sociedad del sur ibérico. Para ello, analizo la evidencia funeraria indígena y cuestiono la división estricta entre cremación e inhumación en la región; así como examino la profundidad y significado de los cambios funerarios en las comunidades locales.

Ruxia i Ruxianos w romansach rycerskich autorstwa Feliciano de Silva

W niniejszym artykule przeanalizowany został sposób wykorzystania przez Feliciano de Silva autentycznego toponimu Ruxia (Ruś) przy konstruowaniu świata przedstawionego w romansie rycerskim. Jak zostaje wykazane, Feliciano de Silva jedynie częściowo wpisuje się w tendencję zaobserwowaną wcześniej m.in. u Garci Rodrigueza de Montalvo, który w swoich dziełach nakreśla jasną opozycję pomiędzy chrześcijańskim światem błędnego rycerstwa a złym i nikczemnym pogaństwem. Autor z Ciudad Rodrigo, chcąc nawiązać do chwały średniowiecznego Konstantynopola, powraca do czasów konfliktu bizantyńsko-ruskiego, który twórczo wykorzystuje w aż trzech księgach Florisel de Niquea. Ruxia, jeden z głównych przeciwników greckiego rodu, przedstawiona zostaje jako pogańska potęga militarna, której przewodzą władcy odważni, lecz zarazem owładnięci żądzą, niemoralni i okrutni.

El color en los códices prehispánicos del México Central: identificación material, cualidad plástica y valor estético

Este artículo investiga algunos de los valores plásticos y estéticos que presidieron la selección y la preparación de las materias colorantes empleadas para iluminar los códices creados por los nahuas del México Central durante el Posclásico Tardío. Estos códices son interesantes porque análisis arqueométricos y exámenes codicológicos recientes han permitido conocer la materialidad de su capa pictórica, así como las características formales y el comportamiento de los colores en estas obras. Uno de los aportes trascendentales de estos estudios ha sido averiguar que la paleta cromática que sirvió para pintar los códices del México Central era principalmente de origen orgánico, lo que contrasta con la naturaleza de los pigmentos detectados en restos de pintura mural y en esculturas creadas por los nahuas que son sobre todo minerales. El objetivo de este artículo es reflexionar sobre las razones de esas diferencias y demostrar que el uso de los colorantes orgánicos en los códices respondía a un fin plástico específico que concordaba con el canon estético imperante en la sociedad náhuatl.

On a first-name basis: Englishization and naming in Flanders

Following and contributing to the ongoing shift from more structuralist, system-oriented to more pragmatic, socio-cultural oriented anglicism research, this paper verifies to what extent the global spread of English affects naming patterns in Flanders. To this end, a diachronic database of first names is constructed, containing the top 75 most popular boy and girl names from 2005 until 2014. In a first step, the etymological background of these names is documented and the evolution in popularity of the English names in the database is tracked. Results reveal no notable surge in the preference for English names. This paper complements these database-driven results with an experimental study, aiming to show how associations through referents are in this case more telling than associations through phonological form (here based on etymology). Focusing on the socio-cultural background of first names in general and of Anglo-American pop culture in particular, the second part of the study specifically reports on results from a survey where participants are asked to name the first three celebrities that leap to mind when hearing a certain first name (e.g. Lana, triggering the response Del Rey). Very clear associations are found between certain first names and specific celebrities from Anglo-American pop culture. Linking back to marketing research and the social turn in onomastics, we will discuss how these celebrities might function as referees, and how social stereotypes surrounding these referees are metonymically attached to their first names. Similar to the country-of-origin-effect in marketing, these metonymical links could very well be the reason why parents select specific “celebrity names”. Although further attitudinal research is needed, this paper supports the importance of including socio-cultural parameters when conducting onomastic research.

Machine learning classification of surgical pathology reports and chunk recognition for information extraction noise reduction

Background and aims: Machine learning techniques for the text mining of cancer-related clinical documents have not been sufficiently explored. Here some techniques are presented for the pre-processing of free-text breast cancer pathology reports, with the aim of facilitating the extraction of information relevant to cancer staging.

Materials and methods: The first technique was implemented using the freely available software RapidMiner to classify the reports according to their general layout: ‘semi-structured’ and ‘unstructured’. The second technique was developed using the open source language engineering framework GATE and aimed at the prediction of chunks of the report text containing information pertaining to the cancer morphology, the tumour size, its hormone receptor status and the number of positive nodes. The classifiers were trained and tested respectively on sets of 635 and 163 manually classified or annotated reports, from the Northern Ireland Cancer Registry.

Results: The best result of 99.4% accuracy – which included only one semi-structured report predicted as unstructured – was produced by the layout classifier with the k nearest algorithm, using the binary term occurrence word vector type with stopword filter and pruning. For chunk recognition, the best results were found using the PAUM algorithm with the same parameters for all cases, except for the prediction of chunks containing cancer morphology. For semi-structured reports the performance ranged from 0.97 to 0.94 and from 0.92 to 0.83 in precision and recall, while for unstructured reports performance ranged from 0.91 to 0.64 and from 0.68 to 0.41 in precision and recall. Poor results were found when the classifier was trained on semi-structured reports but tested on unstructured.

Conclusions: These results show that it is possible and beneficial to predict the layout of reports and that the accuracy of prediction of which segments of a report may contain certain information is sensitive to the report layout and the type of information sought.
