A key aim in biology and psychology is to identify fundamental principles underpinning the behavior of animals, including humans. Analyses of human language and the behavior of a range of non-human animal species have provided evidence for a common pattern underlying diverse behavioral phenomena: Words follow Zipf's law of brevity (the tendency of more frequently used words to be shorter), and conformity to this general pattern has been seen in the behavior of a number of other animals. It has been (...) argued that the presence of this law is a sign of efficient coding in the information theoretic sense. However, no strong direct connection has been demonstrated between the law and compression, the information theoretic principle of minimizing the expected length of a code. Here, we show that minimizing the expected code length implies that the length of a word cannot increase as its frequency increases. Furthermore, we show that the mean code length or duration is significantly small in human language, and also in the behavior of other species in all cases where agreement with the law of brevity has been found. We argue that compression is a general principle of animal behavior that reflects selection for efficiency of coding. (shrink)

Here we study polysemy as a potential learning bias in vocabulary learning in children. Words of low polysemy could be preferred as they reduce the disambiguation effort for the listener. However, such preference could be a side-effect of another bias: the preference of children for nouns in combination with the lower polysemy of nouns with respect to other part-of-speech categories. Our results show that mean polysemy in children increases over time in two phases, i.e. a fast growth till the 31st (...) month followed by a slower tendency towards adult speech. In contrast, this evolution is not found in adults interacting with children. This suggests that children have a preference for non-polysemous words in their early stages of vocabulary acquisition. Interestingly, the evolutionary pattern described above weakens when controlling for syntactic category (noun, verb, adjective or adverb) but it does not disappear completely, suggesting that it could result from a combination of a standalone bias for low polysemy and a preference for nouns.

IntroductionThis study aimed to evaluate, in adults with mild cognitive impairment, the brain atrophy that may distinguish between three AT biomarker-based profiles, and to determine its clinical value.MethodsStructural MRI was employed to evaluate the volume and cortical thickness differences in MCI patients with different AT profiles, namely, A−T−−: normal AD biomarkers; A+T−−: AD pathologic change; and A+T++: prodromal AD. Sensitivity and specificity of these changes were also estimated.ResultsAn initial atrophy in medial temporal lobe areas was found in the A+T−− and (...) A+T++ groups, spreading toward the parietal and frontal regions in A+T++ patients. These structural changes allowed distinguishing AT profiles within the AD continuum; however, the profiles and their pattern of neurodegeneration were unsuccessful to determine the current clinical status.ConclusionsMRI is useful in the determination of the specific brain structural changes of AT profiles along the AD continuum, allowing differentiation between MCI adults with or without pathological AD biomarkers.

parada se ha pre-sentado como una de las gran-des alternativas a la teología de las religiones. Esta idea surge debido al bloqueo que sufrió el triple paradigma promovido por el ‘esquema tipológico’ dentro de la teología de las religiones. Para los teólogos comparatistas esa forma concreta de teología de las religiones no logró respon-der adecuadamente a la necesa-ria tensión que debe mantenerse entre las particularidades cons-titutivas de cada tradición reli-giosa y la apertura dialogante y el aprecio auténtico hacia las otras (...) religiones. La llamada ‘nueva teología comparada’ cree haber encontrado la forma de mantener esa tensión sin renunciar a nin-guno de sus dos principios funda-mentales: identidad y alteridad. (shrink)

The island of Ibiza is a western Mediterranean destination known internationally for its nightlife. The aim of this paper is to make a proposal to classify the different types of premises in the Ibiza nightlife offer. This involves making a first definition that allows to delimit which businesses are parts of the sector. The methodology used is based on the case study and specifically, on the review of the promotional actions and activities carried out, completed with the visit to the (...) premises. The classification has been made based on the offer marketed and not only on the legal forms used, as innovation goes ahead of the existing legal classifications. Although it is a particular application, due to the international importance of Ibiza, it is a good starting point to classify the nightlife offer of many other tourist destinations. The resulting typology divides the sector into two large groups: nightclubs and other premises. While nightclubs have musical parties as their main activity declared, the other premises have accommodation or catering as their main activity, with music being an element of differentiation. Nightclubs are divided into several subgroups, depending on their size and relevance. The other premises are subdivided into Beach Clubs, Hotel Clubs, Party Boats, Lounge Clubs, Disco Pubs, among others. (shrink)

De acuerdo con los informes del Observatorio Español sobre Drogas, organismo institucional responsable del análisis del fenómeno de las drogodependencias en el conjunto de España, en los últimos años de la década del 2000 viene registrándose un descenso general en los consumos de sustancias psicoactivas, tanto de comercio legal como ilegal, tal vez con la única excepción de los hipnosedantes y antidepresivos. Ciertamente esta primera afirmación genérica debe matizarse, ya que este fenómeno no se da de forma similar para todas (...) las sustancias, ni sigue la misma evolución en todos los casos; pero aún así es un hecho constatable que de alguna manera contradice los frecuentes mensajes alarmistas sobre la situación de las drogas, su consumo y las consecuencias de este en nuestro país.

Resumen La figura femenina en el arte cinematográfico ha sido mostrada mediante arquetipos y cumpliendo distintas funciones. Nos proponemos en este estudio analizar los personajes femeninos por medio de la narrativa audiovisual en dos películas emblemáticas de la cinematografía de Hitchcock: Recuerda y Vértigo, en las que la mujer se contempla como empoderada, pero también sometida, llegando a una negación de su propia identidad. Consideramos que la forma del tratamiento de la mujer en el cine de dicha época radica en (...) la situación social de la misma, sufriendo un tratamiento discriminatorio, que es admitido por los personajes femeninos justificándolo en un enamoramiento, que anula la propia personalidad. Abstract The female figure in cinematographic art has been shown through archetypes and performing different functions. We propose in this study to analyze female characters through the audiovisual narrative in two emblematic films of Hitchcock’s cinematography: Spellbound and Vertigo, in which women are seen as empowered, but also subjected to a denial of their own identity. We consider that the treatment of women in the cinema of that time lies in the social situation of the same, suffering a discriminatory treatment, which is admitted by the female characters justifying it in a crush, which annuls the own personality.

BackgroundMany procedures currently require the use of bone grafts to replace or recover bone volume that has been resorbed. However, the patient’s opinion and preferences must be taken into account before implementing any treatment. Researchers have focused primarily on assessing the effectiveness of bone grafts rather than on patients' perceptions. Thus, the aim of this study was to explore patients' opinions regarding the different types of bone grafts used in dental treatments.MethodsOne hundred patients were randomly chosen participated in the study. (...) A standardized survey of 10 questions was used to investigate their opinions regarding the different types of bone grafts used in dental treatments. Descriptive statistics were calculated for the different variables, and absolute frequencies and percentages were used as summary measures. A value of p <0.05 was selected as the threshold for statistical significance.ResultsThe highest rate of refusal was observed for allografts and xenografts. The grafts with the lowest rates of refusal were autologous grafts and alloplastics. No significant differences were found between the various types of bone grafts in the sociodemographic variables or the refusal/acceptance variable. Similarly, no significant relations were observed between a specific religious affiliation and the acceptance/refusal rates of the various types of graft.ConclusionsAllografts and xenografts elicited the highest refusal rates among the surveyed patients, and autologous bone and alloplastics were the most accepted bone grafts. Moreover, no differences were found in the sociodemographic variables or religious affiliations in terms of the acceptance/refusal rates of the different bone grafts. (shrink)

Cybersecurity aggregates are numerical data obtained by aggregation on features along a database of cybersecurity reports. These aggregates are obtained by integration of time-stamped tables using some recent results of non-standard calculus. Time-series of aggregates are shown to contain relevant information about the concrete system dealt with. Trend time series is also forecasted using known data-driven methods. Although absolute forecasting of trend time series is not obtained, a directional forecasting of trend time series is achieved thence validated by means of (...) a rolling cross validation scheme on a public database of Scareware reports.

Knowledge of diverse sexual motivations can have profound implications for our comprehension of the causes, correlations, and consequences of sexual behavior. This study had two objectives: on the one hand, to determine the different motives why young Spanish university students have sex and their relationship with different sociodemographic and psychosexual variables and sexual behavior; on the other hand, to review and improve the psychometric properties of the Sexual Motivations Scale and validate it in Spanish. Participants were 805 university students of (...) both sexes, aged between 18 and 26 years, who completed a battery of online questionnaires. Significant associations were found between young people's sexual motives, especially the motives of coping, peer pressure, and enhancement, the sociodemographic variables, sexual behavior, and psychosexual variables. Also, a new structure of the Sexual Motivations Scale was proposed, with the elimination of the factor of Self-Affirmation. The discussion highlights the relevance of the results obtained due to their implications in the promotion of sexual health, in addition to achieving the first instrument validated in Spanish for the evaluation of sexual motivations.

Assessing physical fitness has emerged as a proxy of the health status of children and adolescents and therefore as relevant from a public health point of view. DAFIS is a project included in Plan Galicia Saudable of the regional government of Galicia. DAFIS consists of an on-line software devoted to record the results of a standard physical fitness protocol carried out as a part of the physical education curriculum. The aims of this study were: to obtain normative values of physical (...) fitness of the Galician school population evaluated in the DAFIS project, and to identify a reduced number of components and tests able to capture a significant amount of the variability in the physical fitness of children and adolescents. From an initial sample of 27784 records, 15287 cases were considered after filtering. Generalized Additive Models for Location, Scale and Shape were used for obtaining percentile curves and tables for each sex. Furthermore, a principal components analysis was performed, selecting the number of components by applying the Kaiser’s rule and selecting a subset of variables considering the correlation between each variable and the components. Percentile curves and normative values are reported for each test and sex. Physical fitness was better in boys than in girls throughout age groups, except for flexibility that was consistently higher in girls. Two main components were detected throughout age groups: the first one representing body composition and partially cardiorespiratory fitness and the second one muscular fitness. For boys and girls, waist to height ratio had the highest correlations with the first component in four out of six age groups. The highest correlation with the second component, was most frequently observed for the handgrip test both in boys and girls. This study provides evidence about the utility of school community actions like DAFIS aimed to track the health-related fitness of children and adolescents. The results suggest that fat mass distribution and muscular performance concentrate a high proportion physical fitness variance. (shrink)

En este trabajo ofrecemos la traducción del latín al español del Liber de convenientia fidei et intellectus in obiecto de Ramón Llull, con introducción y notas. Se trata de una obra en la que el filósofo mallorquín efectúa una síntesis de su pensamiento en torno de las relaciones entre fe y razón, así como de su posición respecto de la defensa de la fe católica y la conversión de los no cristianos. El opúsculo, que se muestra como un trabajo (...) definitivo en cuanto al establecimiento de la relación mencionada, hecha mano de los elementos fundamentales de su sistema, el Ars magna, pero aun así es una rara avis dentro de la opus luliana: está pleno de citas bíblicas y alusiones a las auctoritates eclesiásticas más renombradas, unas y otras ausentes en la mayoría de las obras lulianas. In this paper we offer the translation from Latin to Spanish of Ramón Llull´s Liber de convenientia fidei et intellectus in obiecto with introduction and notes. This is a work where the mallorcan philosopher makes a synthetic framework of his thinking on the relationship between faith and reason, as well as of his position towards the defense of catholic faith and conversion of non-christian people. The text, which is shown as a definitive work in the setting of this relationship, uses the most characteristic principles of his system, Ars magna, but still is a rara avis inside the opus lulliana: is full of biblical quotations and allusions to the most renowned ecclesiastical auctoritates, all these absents in most lullian woks.
