Renormalisation group improvement in the stochastic formalism
2019
We investigate compatibility between the stochastic infrared (IR) resummation of light test fields on inflationary spacetimes and renormalisation group running of the ultra-violet (UV) physics. Using the Wilsonian approach, we derive improved stochastic Langevin and Fokker-Planck equations which consistently include the renormalisation group effects. With the exception of stationary solutions, these differ from the naive approach of simply replacing the classical potential in the standard stochastic equations with the renormalisation group improved potential. Using this new formalism, we exemplify the IR dynamics with the Yukawa theory during inflation, illustrating the differences between …
MINE - Mobile Learning in Higher Education
2018
Mobile technologies are an important part of our daily life and we carry them with us all the time. Mobile learning is already used a lot in informal and non-formal learning, but in the context of formal learning it is not much used, yet. In the area of formal learning at universities, there is a great need for pedagogic scenarios to encourage educatorsto use these new technologies. It is suggested that educators will need to move beyond the didactic approaches still frequently found in higher education. Social constructivist approaches have been advocated, along with the development of communities of practice to support educators. In addition, more emphasis on learners is required, to unde…
La tapicería de la expulsión de los moriscos : un proyecto frustrado de Rodrigo Calderón
2018
espanolEl articulo pone en relacion la serie ya conocida de pinturas titulada «La expulsion de los moriscos del Reino de Valencia» con una documentacion inedita de un encargo realizado por Rodrigo Calderon al virrey de Valencia, marques de Caracena, que incluia, ademas de la narracion de la expulsion, una vista de la ciudad de Valencia y retratos de los protagonistas, y que debia convertirse en una coleccion de tapices nunca realizada. EnglishThis paper deals with an already known series of paintings titled The Expulsion of the Moriscos from the Kingdom of Valencia and provides unpublished documentation of a commission made by Rodrigo Calderon to the viceroy of Valencia, Marquis of Caracena…
Behind the Scenes of Scenario-Based Training: Understanding Scenario Design and Requirements in High-Risk and Uncertain Environments
2017
Simulation exercises as a training tool for enhancing preparedness for emergency response are widely adopted in disaster management. This paper addresses current scenario design processes, proposes an alternative approach for simulation exercises and introduces a conceptual design of an adaptive scenario generator. Our work is based on a systematic literature review and observations made during TRIPLEX-2016 exercise in Farsund, Norway. The planning process and scenario selection of simulation exercises impact directly the effectiveness of intra- and interorganizational cooperation. However, collective learning goals are rarely addressed and most simulations are focused on institution-specif…
Winter long dry spells in the Mediterranean basin and associated atmospheric conditions : contemporary and future variability (1957-2100)
2017
In the context of climate change, as reflected by a dryer Mediterraneanbasin, this thesis focused on the study of the contemporary and future variability(1957-2100) of the wintertime (September to April) very long dryspells events (called VLDSe) in the Mediterranean basin. An original methodologywas developed in this thesis in order to define VLDSe as singularclimatic events, characterized by location, duration and spatial extent criteria.76 VLDSe were detected in the Mediterranean basin on the contemporaryperiod (1957-2013). These events are divided into 4 main geographicalpatterns: North-East, West, Scattered Localized and South-East. North-East and West configurations are associated with…

Enhancing performance of α‐diiminonickel precatalyst for ethylene polymerization by substitution with the 2,4‐bis(4,4'‐dimethoxybenzhydryl)‐6‐methylp…
2020
High activities in ethylene polymerization predetermine α‐diiminonickel precatalysts for potential industrial applications. In our study, we have synthesized and characterized a series of unsymmetrical 1‐(2,4‐bis(4,4′‐dimethoxybenzhydryl)‐6‐MeC6H2N)‐2‐arylimino‐acenaphthylene nickel(II) halides. The single‐crystal X‐ray diffraction study of representative compounds reveals distorted tetrahedral geometry. On activation with either Me2AlCl or modified methylaluminoxane, these nickel complexes exhibit high activities of the order of 106 g of PE (mol of Ni)−1 h−1 and produce polyethylene of generic application characterized by high molecular weight, narrow molecular weight distribution, and mod…

HR scenario game : Learning human resource management in a virtual environment
2021
This paper introduces a computer-based online scenario game that was developed to enhance the learning of human resource management (HRM) in an undergraduate course at a business school in Finland. What makes this game unique is that students played an important and active role in developing the game in collaboration with lecturers. Our findings show that the game enhances learning, interaction, and collaboration among students. We discuss how computer-based games and their development in collaboration with students can be used as a means for learning and improving working-life skills in higher education.
Political risks: the “red shift” in debt sustainability analysis
2020
Political stability and economic policy uncertainty can be key determinants of sovereign debt dynamics, and we show how they can be incorporated in debt sustainability analysis. We distinguish between short-term ambiguity and long-term uncertainty about political risk factors, and using a combination of narrative scenarios and calibrated probabilistic scenarios we obtain a comprehensive heatmap of high-risk debt dynamics. We use Italy as an interesting case study and demonstrate a “red shift” in the assessment of vulnerabilities when accounting for political risks. Ignoring these risks can lead to excessive optimism and wrong decisions.
