The Power of Word-Frequency Based Alignment-Free Functions: a Comprehensive Large-Scale Experimental Analysis
2021
Abstract Motivation Alignment-free (AF) distance/similarity functions are a key tool for sequence analysis. Experimental studies on real datasets abound and, to some extent, there are also studies regarding their control of false positive rate (Type I error). However, assessment of their power, i.e. their ability to identify true similarity, has been limited to some members of the D2 family. The corresponding experimental studies have concentrated on short sequences, a scenario no longer adequate for current applications, where sequence lengths may vary considerably. Such a State of the Art is methodologically problematic, since information regarding a key feature such as power is either mi…
The Effects of Labor and Product Market Reforms: The Role of Macroeconomic Conditions and Policies
2018
The paper estimates the dynamic macroeconomic effects of labor and product market reforms on output, employment and productivity, and explores how these vary with prevailing macroeconomic conditions and policies. We apply a local projection method to a new dataset of major country- and country-sector-level reform shocks in various areas of labor market institutions and product market regulation covering 26 advanced economies over the past four decades. Product market reforms are found to raise productivity and output, but gains materialize only slowly. The impact of labor market reforms is primarily on employment, but it varies across types of reforms and depends on overall business cycle c…
Value Creation and Power Asymmetries in Digital Ecosystems : A Study of a Cloud Gaming Provider
2020
Digital platforms connecting users and service providers have a central role in determining the value creation structure of ecosystems. Platform developers try to achieve a dominant position for the platform with a strong ecosystem around it. The size and attractiveness of the services can attract new users, and growing user volume can bring new co-operative service providers to the service partner network. An interesting question is how the presence of power and potential power asymmetry affect the value creation capability and the structure of a network around a platform? This chapter describes an example of value creation and the influence of power asymmetry in a digital ecosystem built …
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…
What is Experience? : Foucauldian Perspectives
2019
Michel Foucault’s (1926–1984) thought is widely used in the humanities and social sciences for investigating experiences of madness, illness, marginalization and social conflicts. However, the meaning of the word “experience” is not always clearly defined, and the French word expérience has a whole variety of meanings. In this article I explicate Foucault’s most relevant concepts of experience and their theoretical functions. He refers to experience throughout his career, especially in his early texts on existential psychiatry from the 1950s and 1960s and in his late work from the 1980s. Texts such as Mental Illness and Psychology and Dire vrai sur soi-même have received less attention than…

Health system reforms and the needs of the ageing population : an analysis of recent policy paths and reform trends in Finland and Sweden
2022
AbstractPopulation ageing with an increasing number of people experiencing complex health and social care needs challenges health systems. We explore whether andhow health system reforms and policy measures adopted during the past two decades in Finland and Sweden reflect and address the needs of the older people. We discuss health system characteristics that are important to meet the care needs of older people and analyse how health policy agendas have highlighted these aspects in Finland and Sweden. The analysis is based on “most similar cases”. The two countries have rather similar health systems and are facing similar challenges. However, the policy paths to address these challenges are…
On a Continuous Sárközy-Type Problem
2022
Abstract We prove that there exists a constant $\epsilon> 0$ with the following property: if $K \subset {\mathbb {R}}^2$ is a compact set that contains no pair of the form $\{x, x + (z, z^{2})\}$ for $z \neq 0$, then $\dim _{\textrm {H}} K \leq 2 - \epsilon $.
3D high definition video coding on a GPU-based heterogeneous system
2013
H.264/MVC is a standard for supporting the sensation of 3D, based on coding from 2 (stereo) to N views. H.264/MVC adopts many coding options inherited from single view H.264/AVC, and thus its complexity is even higher, mainly because the number of processing views is higher. In this manuscript, we aim at an efficient parallelization of the most computationally intensive video encoding module for stereo sequences. In particular, inter prediction and its collaborative execution on a heterogeneous platform. The proposal is based on an efficient dynamic load balancing algorithm and on breaking encoding dependencies. Experimental results demonstrate the proposed algorithm's ability to reduce the…
Appropriazione e (ri)semantizzazione dello spazio urbano: lo sport in una piazza palermitana
2019
Il contributo, attraverso uno studio di campo, con un approccio geografico culturale esplora le modalità attraverso cui uno spazio urbano, piazza Vittorio Emanuele Orlando a Palermo, può essere oggetto di complessi processi di (ri)semantizzazione. La piazza diviene infatti luogo per sport giovanili improvvisati, al centro di dialettiche opposte (ufficialità/improvisazione) e di forme multistratificate di socialità e aggregazione.
