A method for detecting the profile of an author
No full textThis paper presents a method for detecting an author’s profile using the following two elements: gender and age. This is based on a set of dialogues, written in two languages: English and Spanish, provided for Author Profiling competence within the evaluation forum "Uncovering Plagiarism, Authorship, and Social Software Misuse" (PAN2018). Counts of lexical, semantic, and syntactic characteristics are used to generate a two-phase classification system, which first classifies gender and then age. The results obtained show that, with the amount of data available, it is possible to characterize both the age and gender of an author with an accuracy greater than 50%. However, these values could be improved by having more evidence of information in the training data.Silva, JesusGarcía, SilviaBinda, María AlejandraMarin Gonzalez, FredyBarrios, RosioLeon Castro, Bellani

No full textRadicipes kopelatos sp. nov. (Fig. 2 H, 8, 9) Radicipes sp. 1: Castro et al., 2006: 170 (listed only). Radicipes sp. 2: Castro et al., 2006: 170 (listed only). Holotype: MNRJ 8566, 21° 48 ’ 49 ”S, 40 °01’ 53 ”W, 592.4–618.8 m Paratypes: MNRJ 5968, 13° 22 ’ 17 ”S, 38 ° 36 ’ 56 ”W, 750 m (3 colonies); MNRJ 4361, same collection data of the holotype (55 colonies). Diagnosis: Radicipes with malleable colonies clockwise or counterclockwise spiraled in an upward trend. Axis with iridescent aspect and calcareous rhizoidal holdfast. Slender coenenchyme, easily detachable from axis. Uniserial line of polyps with basal portion appressed to axis and an obliquous distal portion oriented upward. Polyps to 3.5 mm long. Polypar distances 1.0–4.00 mm. Body wall and coenenchyme of polypar line with rods, sometimes flattened, usually with flattened ends, longitudinally arranged. Coenenchymal flattened scales with median waist equally abundant. Sclerites in abpolypar face rare or absent, except on polyp bases. Description of the holotype: Colony whip-like, malleable, unbranched, white, with counterclockwise spiraled upward trend, approximately 28 cm long (Fig. 2 H). Axis with iridescent aspect, 0.7 –1.0 mm diameter, rhizoidal holdfast with 5 main projections, each to 5.7 mm long. Slender coenenchyme, easily detachable from axis. Polyps with basal portion appressed to axis and oblique distal portion 0.8–3.3 mm long, upward oriented (Fig. 8 B), arranged in single longitudinal row along entire colony (uniserial), delimiting one polypar and another abpolypar face, the former usually facing inner part of colony spiral. Inter-polypar distances 1.50–3.40 mm. Density of polyps 2–4 per centimeter. Body wall (Fig. 8 A) and coenenchyme of polypar line (Fig. 8 C) with finely tuberculated rods, sometimes flattened, usually with flattened ends, longitudinally arranged and sometimes sparse, 0.16–0.60 mm long. Coenenchymal flattened scales with median waist equally abundant, 0.15–0.25 mm long (Fig. 8 E). Sclerites in abpolypar face rare or absent except on polyp bases. Adaxial and basal portion of polyps frequently filled with waisted scales similar to those of coenenchyme, slightly smaller than the spindles, 0.10–0.18 mm long (Fig. 8 D). Scales of tentacles striated and ornamented with sparse, small tubercles, 0.08–0.12 mm long (Fig. 8 B). Variability of paratypes: Colonies white or yellowish, also clockwise spiraled in an upward trend (Fig. 9 A), to 58 cm long, with smooth, white, root-like and calcareous holdfast, typical for attaching on soft bottoms (Fig. 9 C). Polyps 0.8–3.5 mm long. Polypar distances 1.0–4.00 mm. Density of polyps usually decreasing in base-apex direction, with up to 5 polyps per centimeter on the proximal 2 / 3 of the colony and 4 – 3 polyps per centimeter on the distal third. Remarks: Radicipes is a monophyletic genus (Pante et al., 2012), but it probably is the one with the poorest descriptions in terms of morphological characteristics within Chrysogorgiidae and a review of its species is imperative. As in other groups within the Chrysogorgiidae, the sclerite forms in Radicipes have little variation (usually rods and scales). The main distinction between species is the distribution of these sclerites throughout the colony and polyp. There are no recent reviews on the genus Radicipes in the Atlantic. The two last works that present some discussion of the genus were given by Deichmann (1936) and Madsen (1944). The former includes the analysis of only one specimen, identified by the author as R. gracilis. Deichmann (1936), however, provides only information already given in the species description by Verrill (1922), not mentioning well-established characteristics in previous taxonomic keys and leaving aside even length measurements of polyps; an important taxonomic character of the group—see Kükenthal (1919, 1924). The study published by Madsen (1944) has the most complete descriptions and illustrations about the genus, but unfortunately includes only Atlantic species. Several important features raised by Madsen (1944) distinguish Radicipes kopelatos sp. nov. from other Atlantic species. Radicipes challengeri has practically no sclerites between the zooids, with spaces of up to 2 mm between coenenchymal sclerites. In Radicipes gracilis, Madsen (1944) describes that the coenenchyme is almost all filled with 8 -shaped challengeri and R. gracilis.?Unknown data scales, whereas R. kopelatos sp. nov. has rods equally abundant. Diagnostic features for all other valid species of the genus are compared to Radicipes kopelatos sp. nov. in Table 2. This is the first description of a species of Radicipes from the South Atlantic. Etymology: Greek kope, f. oar; kopelatos, like an oar (see Brown, 1956: 566); referring to the flattened ends of its coenenchymal rods. Gender male. Distribution: Known only from the type locality, Southeastern Brazil, 592–750 m depth.Published as part of Cordeiro, Ralf T.

The awakening of Dormente: feminism, humour and drama in the new version of the literary classic by Raquel Castro
No full textO presente traballo supón unha pequena achega ao estudo de Dormente, a obra teatral de literatura infantil e xuvenil de Raquel Castro publicada neste ano 2021. A través da súa lectura, dedúcese o propósito da autora por despatriarcalizar o conto de A bela dormente. A tal fin, Castro dota ao renovado discurso de novos contidos e novas formas que distan do clásico, e sobre as que poremos o foco de atención atendendo a varios eixos: trazos feministas, humor e comicidade e estilo.This paper aims to make a contribution to the study of the YA and Children’s play Dormente by Raquel Castro, published in 2021. By reading through her work, it becomes clear the author attempts to “depatriarchalise” the tale of Sleeping Beauty. To achieve this, Castro provides the reader with new content using innovative techniques that differ from the classic tale, thus updating the prevailing narrative. In this review, we will focus on these changes by examining certain key points: feminist features, humour and comedy, and style

On Yager and Hamacher t-Norms and Fuzzy Metric Spaces
No full textRecently, Gregori et al. have discussed (Fuzzy Sets Syst 2011;161:2193 2205) the so-called strong fuzzy metrics when looking for a class of completable fuzzy metric spaces in the sense of George and Veeramani and state the question of finding a non-strong fuzzy metric space for a continuous t-norm different from the minimum. Later on, Gutíerrez-García and Romaguera solved this question (Fuzzy Sets Syst 2011;162:91 93) by means of two examples for the product and the Lukasiewicz
t-norm, respectively. In this direction, they posed to find further examples of nonstrong fuzzy metrics for continuous t-norms that are greater than the product but different from minimum. In this paper, we found an example of this kind. On the other hand, Tirado established (Fixed Point Theory 2012;13:273 283) a fixed-point theorem in fuzzy metric spaces, which was successfully used to prove the existence and uniqueness of solution for the recurrence equation associated with the probabilistic divide and conquer algorithms. Here, we generalize this result by using a class
of continuous t-norms known as ω-Yager t-norms.The second author acknowledges the support of the Ministry of Economy and Competitiveness of Spain under grant MTM2012-37894-C02-01 and the support of Universitat Politecnica de Valencia under grant PAID-06-12-SP20120471.Castro Company, F.; Tirado Peláez, P.

A dependent complex degrading system with non-periodic inspection times
No full textThis paper analyses a system subject to multiple dependent degradation
processes. Degradation processes start at random times following a non
homogeneous Poisson process and next dependently propagate. The growth of these
degradation processes is modeled using gamma increments. We assume that the
arrival of a new process to the system triggers the degradation rate of the
processes present in the system. Under this framework, the analytic expression
of the system reliability is obtained and bounds of the system reliability are
also analyzed. Furthermore, the system is inspected at certain times.
Information on the system health is recorded at these inspection times and the
decision on performing maintenance actions on the system is taken at these
times. We consider in this paper a dynamic inspection policy since the
information that becomes available in an inspection time is taken into account
to schedule the next inspection time. The maintenance cost for this system is
dealt with the use of semi-regenerative process. Numerical examples are
performed to illustrate the analytic expressions.Comment: 31 pages, 10 figure
Bringing S&T Human Resources back in: The Spanish Ramón y Cajal Programme
No full textThis article analyses a government policy initiative that aimed to increase the number of researchers in the public research sector working in conditions equivalent to the tenure track, and to cope with the problems of employability, stabilisation and working conditions of PhDs. The paper describes the situation of science and technology (S&T) human resources in the context of Spanish research policy and explains the mechanisms by which policy-makers link problems and solutions in the context of a policy sequence, by analysing a case that deals with Spain’s main problems in S&T human resources in the public sector
