THE KEY ROLE OF LIQUIDITY FLUCTUATIONS IN DETERMINING LARGE PRICE CHANGES
2005
Recent empirical analyses have shown that liquidity fluctuations are important for understanding large price changes of financial assets. These liquidity fluctuations are quantified by gaps in the order book, corresponding to blocks of adjacent price levels containing no quotes. Here we study the statistical properties of the state of the limit order book for 16 stocks traded at the London Stock Exchange (LSE). We show that the time series of the first three gaps are characterized by fat tails in the probability distribution and are described by long memory processes.
Das kompositorische Verfahren in Jean Moutons Quadrupelkanon Nesciens mater virgo virum
2012
Anhand der kompositorischen Probleme, die sich bei der Konzeption mehr als zweistimmiger Kanons ergeben, wird der Frage nachgegangen, wie der konkrete Kompositionsprozess um 1500 ausgesehen haben konnte. Eine Analyse von Jean Moutons Motette Nesciens mater zeigt, dass die Wechselwirkungen zwischen Kanonkonzeption, Klangfolge und melodischer Gestaltung eine simultane Kompositionsweise voraussetzen, in der die Klangfolge wechselnde Verhaltnisbestimmungen als Resultat und Voraussetzung der kontrapunktischen Konfiguration erfahrt: Der Wechsel von der Sukzessiv- zur Simultankonzeption erscheint in Bezug auf komplexe Kanonbildungen als ein verfahrenstechnisches Erfordernis.
From stage to brain: Montage as a new principle of scientific narrative
2013
German Dadaists, Italian and Russian Futurists and Constructivists created in their experiments multi-medial orthopedic bodies as products of collage and montage. Sergei Eisenstein, who was influenced by these experiments, organized his theatrical productions as a chain of independent fragments capable of entering any possible combination/recombination and labelled this method “montage of attractions”. He used the same montage principle not only for a new theatrical or cinematic narrative but also to conceptualize the expressive movement of the theatrical or cinematic body created on stage and on screen. Finally he conceptualized montage not only as a means of conveying movement, but also o…
Analysis of Word Problems in Primary Education Mathematics Textbooks in Spain
2021
A textbook constitutes the hegemonic material of the educational institution. It acts as a mediator between the official curriculum and the educational practice. Given its potential influence in the classroom, this study analyzes the treatment of word problems included in the mathematics textbooks published by the publishing houses with the greatest diffusion in Spain at every primary education grade. Three variables were analyzed: their semantic structure, their degree of challenge, and their situational context. The results indicate that most of the problems included in textbooks are characterized by low complexity and variability regarding their semantic structure. They are also characte…
Climate change and sustainability in Primary Education. Problems and solutions proposed by the Social Sciences textbooks
2021
El objetivo de esta investigación es analizar las propuestas y actividades relacionadas con la solución a los efectos del cambio climático y la sostenibilidad que se insertan en los actuales libros de texto de Ciencias Sociales españoles (Educación Primaria). A partir de la consulta de las principales editoriales que se usan en España (Anaya, Bromera, Santillana, SM y Vicens Vives), se han analizado los manuales correspondientes al 3er ciclo (5º y 6º). Tras la revisión de estos recursos se han categorizado 3 tipos de soluciones: 1) propuestas sobre recomendaciones a seguir, tanto colectivas como individuales; 2) actividades en las que el alumnado debe proponer soluciones; y 3) información s…

Male coloration and species recognition in sympatric flycatchers
1994
Currently favoured views for explaining ornaments in males emphasize female preference such that females benefit from increased offspring production, good genes of the offspring, or the attractiveness of sons. Results from long-term studies in the pied flycatcher Ficedula hypoleuca suggest that factors associated with species recognition may also be important for male coloration. In sympatry the collared flycatcher F. albicollis is dominant in competition for nesting sites over the pied flycatcher. Bright pied flycatcher males resemble collared flycatcher males and suffer from interspecific interference, whereas dull and female-like males can acquire nesting sites close to those of the coll…
Heterospecific female mimicry in Ficedula flycatchers
2014
Mimicry is a widespread phenomenon. Vertebrate visual mimicry often operates in an intraspecific sexual context, with some males resembling conspecific females. Pied flycatcher (Ficedula hypoleuca) dorsal plumage varies from the ancestral black to female-like brown. Experimental studies have shown that conspecific and heterospecific (collared flycatcher, F. albicollis) individuals of both sexes respond, at least initially, to brown individuals as if they were female. We quantified the perceptual and biochemical differences between brown feathers and found that brown pied flycatcher males are indistinguishable from heterospecific, but not from conspecific, females in both aspects. To our kno…
