Maximal scrambled sets for simple chaotic functions

This paper is a continuation of [V. Jiménez López, An explicit description of all scrambled sets of weakly unimodal functions of type 2∞, Real Anal. Exchange, to appear.], where a explicit description of the scrambled sets of weakly unimodal functions of type 2∞ was given. Its aim is to show that, for an appropriate non-trivial subset of the above family of functions, this description can be made in a much more effective and informative way

Asymptotical periodicity for analytic triangular maps of type less than 2∞

AbstractWe prove that if F is an analytic triangular map of type less than 2∞ in the Sharkovsky ordering, then all points are asymptotically periodic for F. The same is true if, instead of being analytic, F is just continuous but has the property that each fibre contains finitely many periodic points. Improving earlier counterexamples in Kolyada (1992) [16] and Balibrea et al. (2002) [3], we also show that this need not be the case when F is a C∞ map. Finally we remark that type less than 2∞ and closedness of periodic points are equivalent properties in the C1 setting for triangular maps

En torno al conflicto entre nombres de dominio y otros signos distintivos de las empresas: la política uniforme de solución de controversias

Los signos distintivos constituyen instrumentos eficaces y necesarios en la política empresarial que suponen, además, un mecanismo para la protección de los consumidores. Aunque, en sí mismos, los nombres de dominio únicamente representan direcciones numéricas, que permiten la identificación de los ordenadores conectados a la Red, se han convertido en un elemento que da la posibilidad de identificar al titular del servicio Web o los contenidos, productos y/o servicios ofrecidos a través de dicho sitio Web. Los nombres de dominio cumplen las funciones tradicionalmente atribuidas a los signos distintivos, planteándose, en este sentido, ciertos litigios, entre otros aspectos, con otros signos empresariales diversos. En la actualidad, sin perjuicio de las regulaciones nacionales operadas por parte de los diferentes países, el responsable de la administración, en el ámbito mundial, de los nombres y direcciones numéricas de Internet es la organización de carácter internacional ICANN. Cabe reseñar que dicha institución ha articulado un sistema extrajudicial y supranacional en materia de nombres de dominio.The distinctive signs are necessary and effective tools in the business policy that they suppose, and they are also a mechanism for consumer protection. Although the domain names represent only numerical addresses, which allow the identification of the computers connected to Internet, they have become an element that allows the identification of the owner of the website service, or the products and/or services offered through it. Domain na-mes perform the functions traditionally attributed to distinctive sings, and this leads to the establishment of certain litigation with other various business signs. Currently, without affecting the national regulations set in different countries, the responsible for the global administration of the names and numerical addresses of Internet is the international organization ICANN. This institution has articulated a supranational and extrajudicial system for the resolution of problems regarding to the domain names

Fandango de los muertos. 30 años. Crónica de una muerte teatralizada

Con el propósito de testimoniar las treinta temporadas que de El fandango de los muertos se han dado exitosamente en nuestra Máxima Casa de Estudios, no deja de ser pertinente este trabajo que con el título Fandango de los muertos. 30 años. Crónica de una muerte teatralizada nos ofrecen los autores quienes, apoyados en escasa información del autor de la obra con la que cuentan, así como en los correspondientes programas de mano, a la vez que hacen un recuento cronológico de los respectivos repartos, dándole su lugar a cada uno de los participantes, nos permiten hacer en retrospectiva un análisis cronológico de las múltiples representaciones que, a lo largo de sus 30 años ha tenido esta alusiva obra en nuestro ámbito universitario; motivo de orgullo de quienes hemos sido partícipes en algún momento público asiduo, así como para esta institución, una de cuyas más altas funciones es la de promover y difundir la cultura

Sedentary Time Accumulated in Bouts is Positively Associated with Disease Severity in Fibromyalgia: The Al-andalus Project

To examine the associations of prolonged sedentary time (ST) with disease severity in women with fibromyalgia, and to analyse the combined association of total ST and prolonged ST with the disease severity in this population. Women (n = 451; 51.3 +/- 7.6 years old) with fibromyalgia participated. Sedentary time and moderate-to-vigorous physical activity (MVPA) were measured using triaxial accelerometry and ST was processed into 30- and 60-min bouts. Dimensions of fibromyalgia (function, overall, symptoms) and the overall disease impact were assessed with the Revised Fibromyalgia Impact Questionnaire (FIQR). Body fat percentage was assessed using a bio-impedance analyser, and physical fitness was assessed with the Senior Fitness Tests Battery. Greater percentage of ST in 30-min bouts and 60-min bouts were associated with worse function, overall, symptoms and the overall impact of the disease (all, P 60-min bouts) presented lower overall impact compared to participants with high levels of total ST and prolonged ST (mean difference = 6.56; 95% confidence interval (CI) = 1.83 to 11.29, P = 0.002). Greater percentage of ST accumulated in 30- and 60-min bouts and a combination of high levels of total and prolonged ST are related to worse disease severity. Although unable to conclude on causality, results suggest it might be advisable to motivate women with fibromyalgia to break prolonged ST and reduce their total daily ST

Validating the TDRT-Q to assess the quality of the teacher-dancer relationship

La capacidad de los entrenadores para potenciar o desincentivar el compromiso de sus deportistas y para desarrollar su potencial a través de la cualidad de las relaciones que entre ellos se establecen ha recibido una considerable atención desde la investigación; sin embargo, la diada equivalente en el contexto de la danza, la relación entre el maestro y el bailarín, ha sido un área relativamente poco explorada. El propósito de este artículo es extrapolar el modelo de las 3C's de las Relaciones Entrenador-Deportista de Jowett al contexto de la danza y adaptar y validar al español el CART-Q, un instrumento ampliamente utilizado para la evaluación de las relaciones deportista-entrenador. Para ello, 175 bailarines y bailarinas españoles de entre 18 y 40 años (M = 22.47; DT = 4.85) de diferentes niveles y disciplinas de baile completaron el denominado Cuestionario sobre las Relaciones entre Maestro y Bailarín (TDRT-Q), la traducción española del CART-Q adaptado al contexto de la danza. El análisis factorial confirmatorio puso de manifiesto la estructura jerárquica de las relaciones como habían sido originalmente postuladas, incluyendo las dimensiones de Cercanía, Compromiso y Complementariedad. En términos generales, el TDRT-Q demostró unas adecuadas propiedades psicométricas. En línea con los resultados obtenidos, el modelo de las 3C's puede ser transferido para el análisis de las relaciones maestro-bailarín. Más aún, el TDRT-Q puede utilizarse para la evaluación de la cualidad de las relaciones maestro bailarín y para avanzar en el conocimiento y comprensión de este contexto artístico orientado al rendimiento.The capacity of coaches to enable or disable athletes' engagement and ability to reach their potential through the quality of the relationship they develop with them has received substantial research attention, yet the equivalent dyad in dance contexts-the teacher-dancer relationship-has remained relatively unexplored. Thus, the purpose of this paper is to extrapolate Jowett's 3C's Coach-Athlete Relationship Model to the dance context and adapt and validate a Spanish translation of the CART-Q, a psychometric tool that has been extensively used to assess the coach-athlete relationship, to examine the teacher-dancer relationship. 175 Spanish dancers aged 18 to 40 (M = 22.47, SD = 4.85) of diverse performance levels and various dance disciplines completed the renamed Teacher-Dancer Relationship Questionnaire (TDRT-Q), the Spanish translation of the CART-Q adapted to dance contexts. A confirmatory factor analysis highlighted the hierarchical nature of the relationship as has been originally postulated containing Closeness, Commitment, and Complementarity. Overall the TDRT-Q demonstrated adequate psychometric properties. In line with these results, the 3C's model can be transferred to analyse the teacher dancer relationship. Moreover, the TDRT-Q can be used to assess the quality of the teacher-dancer relationship and further advance knowledge and understanding in this achievement-orientated performing arts context.A capacidade dos técnicos para potencializar ou desencorajar o compromisso de seus atletas e para desenvolver o potencial dos mesmos através da qualidade das relações que se estabelecem entre ambos tem recebido considerável atenção da investigação; no entanto, a díade equivalente no contexto da dança, a relação entre o professor e o dançarino, tem sido uma área relativamente pouco explorada.

A topological classification of plane polynomial systems having a globally attracting singular point

In this paper, plane polynomial systems having a singular point attracting all orbits in positive time are classified up to topological equivalence. This is done by assigning a combinatorial invariant to the system (a so-called "feasible set" consisting of finitely many vectors with components in the set $\{n/3: n=0,1,2,\ldots\}$), so that two such systems are equivalent if and only if (after appropriately fixing an orientation in $\mathbb{R}^2$ and a heteroclinic separatrix) they have the same feasible set. In fact, this classification is achieved in the more general setting of continuous flows having finitely many separatrices. Polynomial representatives for each equivalence class are found, although in a non-constructive way. Since, to the best of our knowledge, the literature does not provide any concrete polynomial system having a non-trivial globally attracting singular point, an explicit example is given as well.Comment: 30 pages, 9 figure
