Poincare Inequalities and Spectral Gap, Concentration Phenomenon for G-Measures
2002
We produce a new approach based upon inequalities of Poincare’s type for giving constructive estimates of the mixing rate for a family of mixing stationary processes continuously depending on their past called g-measures. We establish also exponential inequalities of Hoeffding’s type leading to a concentration phenomenon for a large class of observables; this last property permits in particular to give the typical behaviour of the n-orbits of a g-measure.
Regularity of a Degenerated Convolution Semi-Group Without to Use the Poisson Process
2011
We translate in semi-group theory our regularity result for a degenerated convolution semi-group got by the Malliavin Calculus of Bismut type for Poisson processes.
Regional differences in Italian students' performance: a simulation model
2017
This work presents the first results of a research project seeking to build a simulation model able to reproduce the differences of Italian students’ performance at regional level. A preliminary qualitative cause-and-effect model defines the main variable involved in the inter-generational skill formation processes, as well as their interplay with the job market context and the triggering of motivational forces for new skill acquisition. Such model was designed according to a system dynamics perspective, considered suitable for capturing the interrelatedness of key variables and for providing useful simulation tools to conduct and communicate future scenario analyses. Keywords: regional…
Business model scaling and growth hacking in digital entrepreneurship
2023
Creating an innovative product and validating an innovative business model may not be enough for digital startups to be competitive. To grow fast and expand globally, digital startups need to innovate their business model during the scaling phase. A pragmatic approach has recently been proposed to support digital entrepreneurs engaging in business-model innovation during the scaling phase (i.e., business-model scaling), a strategy known as growth hacking. However, we know little about its theoretical grounding and how effective growth hacking is, as businesses lack methodologies to assess its effectiveness before committing resources and investments. To fill this gap, we developed a method …
Zasada bezpośredniości w postępowaniu odwoławczym na tle art. 452 K.P.K. z perspektywy historycznej
2019
Zasada bezpośredniości jest kwalifikowana to tzw. zasad nieskodyfikowanych. Oznacza to, że odkodowanie treści rzeczonej zasady jest możliwe w oparciu o interpretację odpowiedniej grupy przepisów. Art. 452 k.p.k. stanowi fundamentalny przepis, który odpowiada na zasadnicze pytanie dotyczqce zakresu realizowania zasady bezpośredniości w postępowaniu odwoławczym. O zakresie obowiqzywania zasady bezpośredniości w postępowaniu przed sqdem II instancji decyduje model postępowania odwoławczego, kształtowany w oparciuo obowiqzujqce granice dopuszczalnego dowodzenia w instancji odwoławczej. Na skutek przemodelowania postępowania odwoławczego z pełniqcego funkcję wyłqcznie kontrolnq w kierunku postęp…
Justification of point electrode models in electrical impedance tomography
2011
The most accurate model for real-life electrical impedance tomography is the complete electrode model, which takes into account electrode shapes and (usually unknown) contact impedances at electrode-object interfaces. When the electrodes are small, however, it is tempting to formally replace them by point sources. This simplifies the model considerably and completely eliminates the effect of contact impedance. In this work we rigorously justify such a point electrode model for the important case of having difference measurements ("relative data") as data for the reconstruction problem. We do this by deriving the asymptotic limit of the complete model for vanishing electrode size. This is s…
Synchronization of hidden chaotic attractors on the example of radiophysical oscillators
2017
In the present paper we consider the problem of synchronization of hidden and self-excited attractors in the context of application to a system of secure communication. The system of two coupled Chua models was studied. Complete synchronization was observed as for self-excited, as hidden attractors. Beside it for hidden attractors some special type of dynamic was revealed.
Educatio siglo XXI : revista de la Facultad de Educación
2018
El presente estudio describe la competencia digital en el tratamiento de contenidos de Ciencias Sociales de futuros maestros. Para ello se recurre al TPACK (Technological Pedagogical Content Knowledge) y se analizan los resultados de un cuestionario sobre las concepciones al respecto de 153 estudiantes del Grado de Magisterio en Educación Primaria. Las conclusiones confirman un mayor autoconocimiento de contenidos pedagógicos o tecnológicos, frente a los disciplinares, lo que imposibilita, siguiendo la aplicación del modelo, el desarrollo de una competencia digital docente efectiva para el desarrollo de una didáctica crítica en Ciencias Sociales. The present study describes the use of digit…
Filipinas en el marco del imperio español en el siglo XIX
2019
[EN] En este artículo se analiza la evolución de Filipinas en las últimas décadas del siglo XVIII y en el transcurso del siglo XIX a través de diferentes epígrafes: la obligada transformación del secular modelo colonial volcado hacia el tráfico del Galeón y las relaciones transpacíficas; la renovada inclinación hacia Asia, el océano Índico y el mar de China; el desarrollo de un sistema económico basado en la exportación de productos filipinos y en la apertura de las islas al exterior; la evolución de la vida política; el camino hacia la modernización; el peso de las órdenes religiosas, la importancia de la población china y la colaboración con élites indígenas como rasgos singulares de Fili…
超越宣告性模式和判决主义模式* ———麦考密克对“法律推理和法律理论”的重新思考
2019
This paper offers a diachronic reconstruction of MacCormick’s theory of law and legal argumentation: In particular，two related points will be highlighted in which the difference between the perspective upheld in Legal Reasoning and Legal Theory and the later writings is particularly marked． The ? rst point concerns MacCormick’s gradual break with legal positivism，and more speci? cally the thesis that the implicit pretension to justice of law proves legal positivism false in all its different versions． The second point concerns MacCormick’s acceptance of the one－right－answer thesis and the consequent thinning of the differences between MacCormick’s theory of legal reasoning and that of Ronal…
