Mafia e Antimafia

2005

Le dimissioni degli imprenditori Costanzo e Cascio – seduti nei Consigli di Amministrazione di alcune società con gli eredi di Bontate e Teresi – dalle rispettive cariche di presidente di Confindustria Sicilia e di Confindustria Palermo, tornano a riproporre il problema della chiara identificabilità delle infiltrazioni mafiose all’interno del tessuto economico e produttivo dell’Isola e dell’intero Paese. Si tratta di un problema antico e di difficile soluzione; una questione che nel tempo ha contribuito a inaridire il tessuto imprenditoriale siciliano e che ancora oggi disincentiva gli investimenti e l’intrapresa economica. Il potenziale investitore, infatti, deve confrontarsi con la pervas…

Cell-average WENO with progressive order of accuracy close to discontinuities with applications to signal processing

2020

In this paper we translate to the cell-average setting the algorithm for the point-value discretization presented in S. Amat, J. Ruiz, C.-W. Shu, D. F. Y\'a\~nez, A new WENO-2r algorithm with progressive order of accuracy close to discontinuities, submitted to SIAM J. Numer. Anal.. This new strategy tries to improve the results of WENO-($2r-1$) algorithm close to the singularities, resulting in an optimal order of accuracy at these zones. The main idea is to modify the optimal weights so that they have a nonlinear expression that depends on the position of the discontinuities. In this paper we study the application of the new algorithm to signal processing using Harten's multiresolution. Se…

From Signal Processing to Machine Learning

2018

This chapter reviews the main landmarks of signal processing in the 20th century from the perspective of algorithmic developments. It focuses on cross‐fertilization with the field of statistical (machine) learning in the last decades. In the 21st century, model and data assumptions as well as algorithmic constraints are no longer valid, and the field of machine‐learning signal processing has erupted, with many successful stories to tell. The chapter also focuses on digital signal processing (DSP), which deals with the analysis of digitized and discrete sampled signals. Machine learning is a branch of computer science and artificial intelligence that enables computers to learn from data. Mac…

A Biocatalytic Nanomaterial for the Label-Free Detection of Virus-Like Particles

2017

International audience; The design of nanomaterials that are capable of specific and sensitive biomolecular recognition is an on-going challenge in the chemical and biochemical sciences. A number of sophisticated artificial systems have been designed to specifically recognize a variety of targets. However, methods based on natural biomolecular detection systems using antibodies are often superior. Besides greater affinity and selectivity, antibodies can be easily coupled to enzymatic systems that act as signal amplifiers, thus permitting impressively low detection limits. The possibility to translate this concept to artificial recognition systems remains limited due to design incompatibilit…

Didaktiskās spēles kā vārdu krājuma sekmētājas 5-6 gadus veciem bērniem

2017

Bakalaura darbs ,,Didaktiskās spēles kā vārdu krājuma sekmētājas 5-6 gadus veciem bērniem” ir par vārdu krājuma pilnveidošanas iespējām bērniem 5-6 gadu vecumā, izmantojot didaktiskās spēles. Pētījuma mērķis: Izpētīt 5-6 gadus vecu bērnu vārdu krājuma bagātināšanas iespējas, izmantojot didaktiskās spēles. Pirmsskolas vecumā galvenais mācību darbības veids ir rotaļa. Rotaļu, spēļu laikā bērns iegūst jaunas zināšanas, prasmes, attieksmes. Bērns didaktisko spēļu laikā mācās apgūt jaunus vārdus, darina jaunus vārdus, domā teikumus, stāstus, tātad - mācās. Bērns jaunās prasmes apgūst rotaļājoties. Vārdu krājuma pilnveidošana ir viens no būtiskākajiem uzdevumiem darbā ar pirmsskolas vecuma bērnie…

Personality Expression and Impression Formation in Online Social Networks: An Integrative Approach to Understanding the Processes of Accuracy, Impres…

2014

In this paper, we investigate personality expression and impression formation processes in online social networks (OSNs). We explore whether, when and why people accurately judge others’ personalities (accuracy), successfully manage the impressions that others form of them (impression management) and accurately infer others’ impressions of them (meta–accuracy) at zero acquaintance. On the basis of targets’ OSN profiles (N = 103), overall perceiver impressions were collected and compared with targets’ self–view, desired impression and meta–perception. In addition, independent groups of thin–slice perceivers based their personality impressions solely on one of four kinds of information withi…

THE EFFECT OF SOCIETAL COMMUNICATION ON CUSTOMER BEHAVIOR: EVIDENCE FROM THE ENGLISH PREMIER LEAGUE

2012

We present a simple model to estimate the effects on behavior of a group of societal campaigns, aimed at fostering racial equality attitudes. The activity of the Kick it Out is confronted with attendance of English Premier League games. The results support the idea that people weight benefits against results in appraising their willingness to adhere to a campaign. When the foreign player of their own team contributes to results, he is appreciated. At parity of results, the fans prefer players of their own nationality. This indicates that although the campaign may have changed attitudes, it has not changed behavior yet.
