Aqua_Culture: Recognizing New Institutional Models for the Reactivation of Inherent Values in the Urban and Cultural Landscape of Arecibo
Natural resources have dictated the sucessful development of the city of Arecibo until the dissolution of the city\u27s industrial models. This thesis aims to create a Marine Research and Educational Center that promotes the engagement between the city\u27s urban dwellers and its waterfront in a desire to recover the city\u27s valuable historical landscape while promoting new forms of social revitalization through the means of education.\u2
Endoskopische Diagnostik und Therapie der gastrointestinalen Blutung
Zusammenfassung: Die gastrointestinale Blutung stellt unveränderte einen der häufigsten medizinischen Notfälle dar. Obwohl die Mortalität in den letzten Jahren durch Verbesserung der endoskopischen Diagnostik und Therapie leicht gesenkt werden konnte, liegt sie immer noch bei 15%. Zahlreiche Publikationen zu neuen Techniken und Therapiestrategien zeigen kontroverse Ergebnisse, so dass der Endoskopiker in seinen Therapienentscheidungen häufig auf seine persönliche Erfahrung angewiesen ist. Daher werden in diesem Artikel, neben einer neuerer Literaturanalyse zu diesem Thema, Therapieempfehlungen für die Praxis aus dem eigenen Erfahrungsbereich gegebe
Does society show differential attention to researchers based on gender and field?
While not all researchers prioritize social impact, it is undeniably a
crucial aspect that adds significance to their work. The objective of this
paper is to explore potential gender differences in the social attention paid
to researchers and to examine their association with specific fields of study.
To achieve this goal, the paper analyzes four dimensions of social influence
and examines three measures of social attention to researchers. The dimensions
are media influence (mentions in mainstream news), political influence
(mentions in public policy reports), social media influence (mentions in
Twitter), and educational influence (mentions in Wikipedia). The measures of
social attention to researchers are: proportion of publications with social
mentions (social attention orientation), mentions per publication (level of
social attention), and mentions per mentioned publication (intensity of social
attention). By analyzing the rankings of authors -- for the four dimensions
with the three measures in the 22 research fields of the Web of Science
database -- and by using Spearman correlation coefficients, we conclude that:
1) significant differences are observed between fields; 2) the dimensions
capture different and independent aspects of the social impact. Finally, we use
non-parametric means comparison tests to detect gender bias in social
attention. We conclude that for most fields and dimensions with enough non-zero
altmetrics data, gender differences in social attention are not predominant,
but are still present and vary across fields.Comment: 23 pages, 5 figures, 7 table
Enseñanza de la Informática en el marco de la Educación Musical
En este artículo se presenta un nuevo enfoque para la enseñanza de las nuevas tecnologías aplicadas a la música. Nuestro objetivo es promover el aprendizaje activo de conceptos y el manejo de herramientas que favorezcan, en lo posible, la adquisición de experiencia. Se propone para ello unos sencillos pero efectivos ejercicios que están siendo utilizados en la asignatura Informática Básica de la Titulación de Maestro Especialista en Educación Musical impartida en la Universidad de La Laguna
Discovery of a massive supercluster system at
Superclusters are the largest relatively isolated systems in the cosmic web.
Using the SDSS BOSS survey we search for the largest superclusters in the
redshift range .
We generate a luminosity-density field smoothed over
to detect the large-scale over-density regions. Each individual over-density
region is defined as single supercluster in the survey. We define the
superclusters in the way that they are comparable with the superclusters found
in the SDSS main survey.
We found a system we call the BOSS Great Wall (BGW), which consists of two
walls with diameters 186 and 173 Mpc, and two other major superclusters
with diameters of 64 and 91 Mpc. As a whole, this system consists of
830 galaxies with the mean redshift 0.47. We estimate the total mass to be
approximately . The morphology of the
superclusters in the BGW system is similar to the morphology of the
superclusters in the Sloan Great Wall region.
The BGW is one of the most extended and massive system of superclusters yet
found in the Universe.Comment: 4 pages, accepted as a letter in A&

La Intercomprensió d'interrogatives absolutes amb tonemes descendents del català, de l'espanyol de les canàries i del gallec
L'estudi se centra en les oracions interrogatives del català parlat a Barcelona, de l'espanyol de Canàries parlat a Tenerife i el gallec parlat a Santiago de Compostel.la. Després d'una breu descripció acústica de la melodia de cada llengua, les frases que constitueixen el corpus (frases de tres accents tonals cadascuna) se sotmeten a tests perceptius després de ser sintetitzades i de ser eliminat el seu contingut lèxic que es presenta a oients de tots tres punts d'enquesta. Els resultats indiquen que, tot i que cada grup d'oients reconeix amb més facilitat i interpreta com a més «normals» les frases que corresponen a la seva varietat lingüística, la intercomprensió entre els parlants de les llengües romàniques estudiades és prou bona.This paper presents a study of interrogative sentences in the Catalan of Barcelona, the Spanish of Tenerife in the Canary Islands, and the Galician spoken in Santiago de Compostela. After a brief acoustic description of the melody used in each language variety, the results of perception tests carried out with subjects from the three areas of study on the sentences in the corpus (each containing three pitch accents) are given, the sentences first having been synthesized and stripped of their lexical content. The results show that, although each group of subjects recognize more easily and consider more normal the sentences from their own linguistic variety, mutual intelligibilty among speakers of the Romance varieties studied is good
Variable Stars in Local Group Galaxies. IV. RR Lyrae stars in the central regions of the low-density galaxy Crater II
We present a search and analysis of variable stars in the recently discovered
Crater~II dwarf galaxy. Based on , , data collected with the Isaac
Newton Telescope (FoV0.44 square degrees) we detected 37 variable stars,
of which 34 are bone-fide RR Lyrae stars of Crater~II (28 RRab, 4 RRc, 2 RRd).
We applied the metal-independent (, ) Period--Wesenheit relation and
derived a true distance modulus ( = 20.300.08 mag (=0.16
mag). Individual metallicities for RR Lyrae stars were derived by inversion of
the predicted -band Period-Luminosity relation. We find a mean metallicity
of [Fe/H]=-1.64 and a standard deviation of =0.21 dex,
compatible with either negligible or vanishing intrinsic metallicity
dispersion. The analysis of the Colour-Magnitude Diagram reveals a stark
paucity of blue horizontal branch stars, at odds with other Galactic dwarfs,
and globular clusters with similar metal abundances.Comment: 14 pages, 8 figures, accepted for publications on MNRAS. Time series
