In this paper, we characterize the global phase portrait of the Riccati quadratic polynomial differential system ẋ = α2(x), ẏ = ky2 + β1(x)y + γ2(x), with (x,y)∈R2, γ2(x) nonzero (otherwise the system is a Bernoulli differential system), k ≠ 0 (otherwise the system is a Liénard differential system), β1(x) a polynomial of degree at most 1, α2(x) and γ2(x) polynomials of degree at most 2, and the maximum of the degrees of α2(x) and ky2 + β1(x)y + γ2(x) is 2. [...]

In Artés et al. (Geometric configurations of singularities of planar polynomial differential systems. A global classification in the quadratic case. Birkhäuser, Basel, 2019) the authors proved that there are 1765 different global geometrical configurations of singularities of quadratic differential systems in the plane. [...]

The present study aimed to measure motivation in physical education by the Perceived Locus of Causality Scale (PLOC) within a cross-cultural context. A sample of 2,293 adolescents from China (n = 1,287) and Spain (n = 1,006) completed the scales. [...] El presente estudio intentó a medir la motivación en educación física por la Escala de locus de causalidad percibido (PLOC) dentro un contexto transcultural. En total 2,293 adolescentes de China (n = 1,287) y de España (n = 1,006) completaron las escalas. [...] O presente estudo teve como objetivo mensurar motivação na educação física pelo Escala do locus de causalidade percibido (PLOC) dentro de um contexto transcultural.

¿Responden los diccionarios italianos al boom de la cirugía estética? : Aproximación lexicográfica y traductológica mediante un estudio de caso
/
Rodríguez Reina, Pilar (Universidad Pablo de Olavide)
Estamos asistiendo en la actualidad a una especie de democratización de las operaciones de cirugía estética, que está generando la introducción de un léxico especializado del sector en la lengua de un hablante común. [...] Attualmente stiamo assistendo a una sorta di democratizzazione degli interventi di chirurgia estetica, che sta comportando l'introduzione di un lessico specializzato del settore nella lingua del parlante comune. [...] Estem assistint en l'actualitat a una mena de democratització de les operacions de cirurgia estètica, que està generant la introducció d'un lèxic especialitzat del sector en la llengua d'un parlant comú. [...] The nowadays democratization of cosmetic surgery means that lexicon of this specialized domain is being greatly used by non-specialist speakers. A corpus consisting of several Italian cosmetic surgery websites and glossaries will be a starting point for analysing how general dictionaries reflect this specialized language. [...]
