La Calidad televisiva : análisis comparativo de los informativos Telenotícies Vespre y Noticias Cuatro

El treball que presentem a continuació pretén oferir una perspectiva general sobre les investigacions realitzades entorn a la qualitat televisiva per tal d'extreure una sèrie de criteris que es puguin aplicar en una anàlisi d'informatius de televisió. Per a això, presentem una panoràmica general de les investigacions que s'han dut a terme sobre qualitat televisiva i destaquem les principals valoracions del concepte "qualitat". D'aquesta manera, aplicant els criteris estudiats a la mostra seleccionada, podem extreure unes conclusions més precises sobre l'anàlisi de qualitat en els noticiaris

La Promoción de libros impresos a través de Twitter : análisis de los casos Ediciones Deusto, Gestión 2000 y Alienta Editorial

El sector editorial a Espanya s’ha vist obligat a canviar el seu model de negoci a partir de la Revolució Digital del S.XXI. Això inclou la utilització de mitjans socials a través dels quals es busca, entre altres coses, una nova forma de promoció dels seus llibres i un apropament a les noves tendències de la comunicació per a una efectiva relació amb els seus lectors. Recolzat en les teories de la comunicació digital, aquest treball té l’objectiu d’explorar la promoció de llibres imprès a Twitter mitjançant el hashtag. Es du a terme utilitzant una metodologia qualitativa que ha permès fer un ajust entre les dades i la realitat actual de l’ús d’aquesta eina dintre del sector editorial, i per tant ofereix algunes bases i teories per a futures investigacions

Fish ecology in Lake Banyoles (NE Spain): a tribute to Ramon Margalef

Lake Banyoles is the second largest lake in the Iberian Peninsula and due to this relative uniqueness, its peculiar geological origin, and its considerable age attracted the early attention of the late Professor Ramon Margalef. One of the first papers by Margalef was on the biota of Lake Banyoles and two of the first four Ph.D. theses that he supervised were about the limnology of this lake. Unfortunately, the uniqueness of this lake also implied that it was the first place of introduction into the Iberian Peninsula of several exotic fish species, early in the XXth Century and nowadays the lake fish assemblage is dominated by invasive species, and some native ones have been extirpated. Although the limnological studies in Lake Banyoles were pioneering within the Iberian Peninsula, studies on fish ecology of the lake did not start until 1989. Thereafter, four Ph.D. theses have been completed on different aspects of the fish assemblages of Lake Banyoles. The aim of this paper is to provide a short overview of this research, largely brought about by the considerable limnological information previously available for this lake, thanks to the insightful, pioneering work of Professor Margalef

Characterization of intonation in Karṇāṭaka music by parametrizing context-based Svara Distributions

Intonation is a fundamental music concept that has a special relevance in Indian art music. It is characteristic of the rāga and intrinsic to the musical expression of the performer. Describing intonation is of importance to several information retrieval tasks like the development of rāga and artist similarity measures. In our previous work, we proposed a compact representation of intonation based on the parametrization of the pitch histogram of a performance and demonstrated the usefulness of this representation through an explorative rāga recognition task in which we classified 42 vocal performances belonging to 3 rāgas using parameters of a single svara. In this paper, we extend this representation to employ context-based svara distributions, which are obtained with a different approach to find the pitches belonging to each svara. We quantitatively compare this method to our previous one, discuss the advantages, and the necessary melodic analysis to be carried out in future.

Participació de les aigües subterrànies en la gènesi d'ambients palustres continentals: el cas dels prats de Sant Sebastià (Caldes de Malavella, Girona)

The area known as 'prats de Sant Sebastià' is in Caldes de Malavella. It is part of the wetlands located in the south-eastern end of the Selva Basin. Several areas with unusually high conductivity (EC up to 24,500 uS/cm) have been identified in this place. This fact allows highly specialised and comparatively rare botanical species to grow in this area. These saline soils follow a north-south line-up. The geophysical data, obtained with a field conductivemeter (EM 31), show that this superficial line-up continues in the subsoil. In addition to this, the conductivity cartography, made for an electromagnetic exploration depth of 6 meters, shows that the width of the region where these salinity anomalies take place increases in depth. When included in the hidrogeological context of this sector of the Selva Basin, these data bring new elements for the study of the genesis and working of these marshy environments.The model that future research will have to confirm, maintains that the groundwater discharges coming from the underlying hydrogeothermal aquifer are a conditioning factor of the aforementioned phenomenon. This ascending flow of highly mineralised waters (TDS of about 3,500 mg/l) can produce and keep stable the soil salinity
