An intelligent system for risk classification of stock investment projects

The proposed paper demonstrates that a hybrid fuzzy neural network can serve as a risk classifier of stock investment projects. The training algorithm for the regular part of the network is based on bidirectional incremental evolution proving more efficient than direct evolution. The approach is compared with other crisp and soft investment appraisal and trading techniques, while building a multimodel domain representation for an intelligent decision support system. Thus the advantages of each model are utilised while looking at the investment problem from different perspectives. The empirical results are based on UK companies traded on the London Stock Exchange

Oral History as Inquiry: Using Digital Oral History Collections to Teach School Desegregation

A body of literature in both history and history education indicates that when it comes to contemporary historical issues, oral history is one of the essential sources to investigate the past, particularly as a source for “history from below,” experiences of those who were undocumented or ill-recorded. Most of all, with new digital technologies, oral histories are more accessible than ever to those who are interested in using them in their research and teaching. This article uses the topic of school desegregation as a case study to highlight the value of oral histories as a historical methodology for studying the past and a pedagogical tool for teaching

MTradumàtica : statistical machine translation customisation for translators

This article presents the results of the research project ProjecTA, which attempts to bring machine translation within closer reach of translators. This works from the basic assumption that the translator's profile is valid for managing MT-related tasks. The first phase of this project consisted of researching to what degree translation agencies in Catalonia and Spain use MT, via a survey sent to translation companies. The results showed that MT is used very little by micro and small enterprises, which led to the second phase of this project, namely to develop a free MT platform, MTradumàtica, specifically designed for translator

New or Incompletely Known Species of Feltria from North America (Acarina: Feltriidae)

The genus Feltria has a widespread Holarctic distribution. A few species (Lundblad, 1941, 1969) have also been reported from northern Burma but this latter area. as far as its water mite fauna is concerned, might better be considered part of the southern border of the Palearctic, rather than a part of the Oriental Region. Previously. thirty apparently valid species and subspecies of Feltria were known from North America. The present paper describes nine additional forms and brings the total from the Nearctic area to 39, which is nearly identical with the number known from Europe. Most North American species are found in mountainous regions, but four are known from cold streams and springs in Michigan. The majority of Nearctic species are found associated with mosses and other matted aquatic plants, but twelve (including four described in this paper) are typically residents of the interstitial water associated with stream sand and gravel deposits. For reasons to be listed along with the description of Feltria testudo n. sp., the genus Azugofeltria is reduced to the rank of subgenus. The terminology used in describing musclt: attachment plates and glandularia of the dorsum follows that of Cook (1961). In presenting measurements, those of the holotype and allotype are given first. If a series of specimens is available, the range of variation is given in parentheses following the measurements of the primary types. Holotypes and allotypes will be deposited in the Field Museum of Natural History (Chicago)

Re-evaluating the Mausoleum of Galla Placidia

The Mausoleum of Galla Placidia has generated a lengthy bibliography over the centuries but, in spite of repeated investigations, the north and south arm barrel vaults have received almost no attention. Commentary on these areas of the mosaic program is usually brief and limited to a comparison between the appearance of the barrel vaults and patterns found in various textiles, such as carpets. This thesis seeks to fill the void in the body of scholarly research pertaining to the north and south arm barrel vaults by viewing their decorative motifs through the eyes of a fifth-century Christian. When seen from this perspective two distinct motifs rich in iconographical meaning emerge from the composition: concentric circles and flora. In the Early Christian period, concentric circles and mirrors were synonymous with one another and both were believed to possess apotropaic powers capable of warding off evil spirits. Flowers in art could be used to designate a space as a garden and, when shown in perpetual full bloom in a funerary context, mark the space as the Earthly Paradise. Questions about the intended function, the patron, and the exact date of this building have long been subjects of lively debate. The issue of the intended function of the space is at the heart of this inquiry; this monograph accepts without argument the widely held view that Galla Placidia erected the edifice in the first half of the fifth century, most likely around 425 CE. I believe that the meaning behind the pattern of the north and south arm barrel vaults can be extrapolated to the mosaic program of the space as a whole in support of the theory that the building was constructed with an expressly funerary function in mind

A Historical Perspective of the Atlantic’s Evolution

SFRH/BPD/75764/2011 UID/CPO/04627/2013 565280-EPP-1-2015-1-USEPPJMO-NETWORKIn the last two centuries, several key moments have defined the Atlantic Basin’s history that help us understand its present. This chapter endeavours to present a comprehensive overview of this evolution, pointing out key events that set up the historical links that still play a role in the Atlantic. In the first section, following a chronological approach, it shows how the American and the French Revolutions were milestones in the balance of power in this area. Since then, a division between Europe, the Americas and Africa has evolved beyond the common historical, cultural and linguistic ground that composes the Atlantic. The second section attempts to show how human flows, economic exchanges and energy resources in the Atlantic remain the chief common drivers shaping the division of the Atlantic, contributing, paradoxically, to an interdependent evolution of the basin even during periods of political separation. Finally, the third section focuses on the 20th century, which is marked by several attempts at rapprochement between the various sides of the Atlantic. Following the rise of the United States as hegemonic power, this process led to a greater closeness between both sides of the North Atlantic, yet failed to yield results due to the gradual emergence of new powers in the South Atlantic. The Atlantic is still a heterogeneous and divided region, mostly due to geopolitical and ideological factors. However, its multilateral tradition and the development of different regional integration schemes might help to foster cooperation between the various shores.publishersversionpublishe

Pan-Arctic distribution of bioavailable dissolved organic matter and linkages with productivity in ocean margins

Rapid environmental changes in the Arctic Ocean affect plankton productivity and the bioavailability of dissolved organic matter (DOM) that supports microbial food webs. We report concentrations of dissolved organic carbon (DOC) and yields of amino acids (indicators of labile DOM) in surface waters across major Arctic margins. Concentrations of DOC and bioavailability of DOM showed large pan-Arctic variability that corresponded to varying hydrological conditions and ecosystem productivity, respectively. Widespread hot spots of labile DOM were observed over productive inflow shelves (Chukchi and Barents Seas), in contrast to oligotrophic interior margins (Kara, Laptev, East Siberian, and Beaufort Seas). Amino acid yields in outflow gateways (Canadian Archipelago and Baffin Bay) indicated the prevalence of semilabile DOM in sea ice covered regions and sporadic production of labile DOM in ice-free waters. Comparing these observations with surface circulation patterns indicated varying shelf subsidies of bioavailable DOM to Arctic deep basins.Published version2019-07-3

La sobretitulació d'obres teatrals

L'article tracta la sobretitulació electrònica interlingüística d'obres teatrals representades en directe. Primer, ofereix un breu repàs a la història de la sobretitulació de teatre i òpera i després se centra en tres exemples concrets que han suposat un repte especialment gran per al traductor, el muntatge suís Mnemopark, l'obra anglesa A Disappearing Number i el muntatge alemany Nord, totes tres representades al Teatre Lliure de Barcelona. L'article descriu el procediment i els diferents passos que se segueixen per a dur a terme tant la subtitulació general com la sobretitulació d'obres de teatre. L'objectiu de l'article també és mostrar la poca consideració amb què compta entre el públic i sobretot les companyies teatrals.This article focuses on the interlingual electronic subtitling of live performed plays.
