Léxico románico I. La penetración de hispanismos en la Italia meridional
Este Trabajo de Fin de Grado (TFG) pretende realizar, a través del estudio del
léxico, un análisis de la influencia de la cultura española en los territorios italianos que
estuvieron bajo el dominio de la corona, concretamente en Sicilia y Nápoles. Partiendo
de la historia que comparten ambas regiones, revelaremos la importancia de conocer las
relaciones políticas, económicas y culturales para entender la difusión de numerosos
préstamos del catalán y del castellano en los dialectos del sur de Italia; a continuación,
presentaremos las diferencias y similitudes que caracterizaron el contacto lingüístico
que se produjo a lo largo de los años, y finalizaremos con la exposición de las
conclusiones y reflexiones finales en torno al tema, a raíz de los resultados obtenidos en
el estudio individual de los términos: el léxico en la isla de Sicilia se enriqueció gracias
al contacto lingüístico de sus hablantes con el catalán y el castellano; el primero generó
un bilingüismo que alcanzó todos los estratos sociales, aunque la mayoría de los
préstamos que se introdujeron en el dialecto italiano fueron los referidos al campo de la
marina y el comercio; los préstamos del castellano, por otro lado, quedaron restringidos
principalmente al ámbito administrativo y militar, y con la decadencia del imperio,
revelaron la debilidad del influjo español. El contacto lingüístico en Nápoles se produjo
en la época de mayor esplendor de la lengua española, de modo que podemos encontrar
un elevado número de hispanismos en el dialecto que afectan a todo tipo de campos
semánticos; no obstante, desde principios del siglo XVI el español había sido la lengua
de moda en Europa, por lo que muchos de esos préstamos se introdujeron en el
napolitano a través del italiano y no directamente

Artificial Nourishment in the catalan coast
La proliferació dels ports i espigons artificials ha provocat que el transport longitudinal quedi barrat i que
la sorra s’acumuli asimètricament impedint, en molts casos, la recuperació posterior als grans temporals.
Aquest fet sumat a la disminució dels aportaments fluvials, degut a les obres de provisionament hídric i
de producció elèctrica ha fet disminuïr sensiblement la disponibilitat de sediment de les platges. Amés a
més des dels anys 60 i amb l’ascens de l’indústria turística, els assentaments costaners s’han multiplicat
de forma espectacular, augmentant dramàticament la potencialitat d’impacte sobre el litoral. Els efectes
negatius derivats d’aquests tipus d’assentaments són múltiples i complexos, ja que habitualment
l’urbanització costanera sol venir acompanyada d’altres obres auxiliars que satisfaguin les demandes
turístiques: vies de comunicació (carreteres, estacionaments,..), ports esportius, passejos marítims, etc.
Tots aquests assentaments es solen ubicar el més pròxim possible a la línia de costa, ocupant la franja
costanera interna i augmentant així les possibilitats de veure’s afectats pels processos físics litorals de
caràcter destructiu (temporals, innundacions, etc..)
Uncertain research country rankings. Should we continue producing uncertain rankings?
Citation based country rankings consistently categorize Japan as a developing
country, even in those from the most reputed institutions. This categorization
challenges the credibility of such rankings, considering Japan elevated
scientific standing. In most cases, these rankings use percentile indicators
and are accurate if country citations fit an ideal model of distribution, but
they can be misleading in cases of deviations. The ideal model implies a
lognormal citation distribution and a power law citation based double rank: in
the global and country lists. This report conducts a systematic examination of
deviations from the ideal model and their consequential impact on evaluations.
The study evaluates six selected countries across three scientifically relevant
topics and utilizes Leiden Ranking assessments of over 300 universities. The
findings reveal three types of deviations from the lognormal citation
distribution: i deviations in the extreme upper tail; ii inflated lower tails;
and iii deflated lower part of the distributions. These deviations stem from
structural differences among research systems that are prevalent and have the
potential to mislead evaluations across all research levels. Consequently,
reliable evaluations must consider these deviations. Otherwise, while some
countries and institutions will be correctly evaluated, failure to identify
deviations in each specific country or institution will render uncertain
evaluations. For reliable assessments, future research evaluations of countries
and institutions must identify deviations from the ideal model.Comment: 29 pages, 6 figures, 5 table
Countries pushing the boundaries of knowledge: the US dominance, China rise, and the EU stagnation
Knowing which countries contribute the most to pushing the boundaries of
knowledge in science and technology has social and political importance.
However, common citation metrics do not adequately measure this contribution.
This measure requires more stringent metrics appropriate for the highly
influential breakthrough papers that push the boundaries of knowledge, which
are very highly cited but very rare. Here I used the recently described Rk
index, specifically designed to address this issue. I applied this index to 25
countries and the EU across 10 key research topics, five technological and five
biomedical, studying domestic and international collaborative papers
independently. In technological topics, the Rk indices of domestic papers show
that overall, the USA, China, and the EU are leaders; other countries are
clearly behind. The USA is notably ahead of China, and the EU is far behind
China. The same approach to biomedical topics shows an overwhelming dominance
of the USA and that the EU is ahead of China. The analysis of internationally
collaborative papers further demonstrates the US dominance. These results
conflict with current country rankings based on less stringent indicators.Comment: 18 pages, 1 figure, 6 table
A Simple Index for the High-Citation Tail of Citation Distribution to Quantify Research Performance in Countries and Institutions
Conventional scientometric predictors of research performance such as the number of papers, citations, and papers in the top 1% of highly cited papers cannot be validated in terms of the number of Nobel Prize achievements across countries and institutions. The purpose of this paper is to find a bibliometric indicator that correlates with the number of Nobel Prize achievements.-index has superior features as compared to the other two parameters. Nobel Prize achievements are low frequency events and their number is an imprecise indicator, which in addition is zero in most institutions; the evaluation of research making use of the number of publications in prestigious journals is not advised.-index is a simple and precise indicator for high research performance
Design strategies in facades for the reduction of housing energy consumption
This article analyzes the energy-saving potential of various facade design strategies from a life cycle perspective, including the energy needed in the use stage and the embodied energy of materials. The results provide reference data on the behaviour of these systems in Spain and make it possible to identify the best strategies for reducing energy consumption in a wide variety of potential situations that may arise in both new construction and in the rehabilitation of existing facades. The impact categories studied are fossil fuel depletion and climate change, and design strategies are linked to climate data, orientation, air change rate, facade materials and wall composition. Exchanges between the interior and exterior environments take place through the building envelope, some of whose key design parameters include lighting, ventilation and heat flux. Improving this envelope can greatly reduce environmental impact, ensuring indoor environmental quality. This analysis confirms the need to consider the interactions among the parameters studied, as it shows that there are several design solutions with similar impacts, which can be adapted to project requirements. In both new construction and rehabilitation, some of these parameters may be determined by other design decisions not necessarily aimed at reducing environmental impact, so it can be very useful to be aware of a variety of design alternatives that can be implemented in specific projects
Toxicity and Neuropharmacological Effects of Elenine
Elenine is the aglycone of elenoside, a cytotoxic arylnaphthalene lignan (NSC
644013-W/1) derived from Justicia hyssopifolia. (Family: Acanthaceae). Elenoside
is a β-D-glucoside, with a similar chemical structure to etoposide, exhibiting
central depressant activity. In the present study, elenine was given to mice and
rats at doses of 10, 20, and 40 mg/kg. Acute toxicity (24 h) and general
behaviour in mice was studied as well as its effects on muscular relaxant
activity, locomotor activity (Varimex test), and the open-field test and were compared
with 10 mg/kg of chlorpromazine. Elenine produced a reduction in the
permanence time in muscular relaxant activity (traction test). Spontaneous
activity was lower in the Varimex test. The ambulation and rearing were lower
compared with the control group, and an increase in boluses was observed in the
open-field test. Thus, it can be concluded that elenine has central sedative
effects at lower doses than those used with elenoside and has a possible
application in conditions of anxiety
