Modeling the Target-Note Technique of Bebop-Style Jazz Improvisation: An Artificial Neural Network Approach

1995

In cognitive science and research on artificial intelligence, there are two central paradigms: symbolic and analogical. Within the analogical paradigm, artificial neural networks (ANNs) have recently been successfully used to model and simulate cognitive phenomena. One of the most prominent features of ANNs is their ability to learn by example and, to a certain extent, generalize what they have learned. Improvisation, the art of spontaneously creating music while playing or singing, fundamentally has an imitative nature. Regardless of how much one studies and analyzes, the art of improvisation is learned mostly by example. Instead of memorizing explicit rules, the student mimics the playing…

Melodic improvisation at the age of 6–11 years: Development of pitch and rhythm

2007

The keyboard melodic improvisations of 6–11-year-old children (N = 36) were explored for age-related development and representational types of production. The hypotheses were founded on a model of musical development by the present author. The participants heard a 24-bar ABA-formed piano-bass-percussion- accompaniment. Section A was tonal and section B was modal, lacking the tonic. Age was a significant factor in the development of the tonal hierarchy. The 6–7-year-old children's general emphasis was on the first five tones of the diatonic scale. The 8–9-year-old children preferred tones present in both sections (event hierarchical orientation). In the 10–11-year-old children's products, t…

Influence of expressive versus mechanical musical performance on short-term memory for musical excerpts

2012

Recognition memory for details of musical phrases (discrimination between targets and similar lures) improves for up to 15 s following the presentation of a target, during continuous listening to the ongoing piece. This is attributable to binding of stimulus features during that time interval. The ongoing-listening paradigm is an ecologically valid approach for investigating short-term memory, but previous studies made use of relatively mechanical MIDI-produced stimuli. The present study assessed whether expressive performances would modulate the previously reported finding. Given that expressive performances introduced slight differences between initially presented targets and their target…

Divari macro-regionali nella diffusione del microcredito

2016

Il microcredito è uno strumento di contrasto all’esclusione finanziaria, ossia “una condizione di inabilità degli individui, famiglie o gruppi ad accedere a servizi finanziari di base in una forma appropriata, tale da consentire lo svolgimento di una normale vita sociale nella società di appartenenza” (Commissione Europea, 2008). Tale impedimento può essere causato ad esempio da una scarsa cultura finanziaria, un senso di sfiducia degli individui verso l’utilizzo dei servizi finanziari, livelli insufficienti di reddito (Mckillop e Wilson, 2007; Kempson et al. 2007; Mitton, 2008; Anderloni e Carluccio, 2006; Claessens e Demirguc-Kunt, 2006). Alcune categorie sociali connotate dal possess…

Imprese nel quotidiano. Il lavoro autonomo dei migranti a Palermo: una ricerca esplorativa

2007

Questo studio analizza l’esperienza di alcuni migranti che svolgono un lavoro autonomo a Palermo, inquadrandola in una realtà più vasta, attraverso il riferimento non solo ai principali studi sociologici, ma anche ai dati quantitativi sull’argomento. In tal modo, si mira ad integrare la prospettiva macro-sociale con quella micro.

Quantum and carbon dots conjugated molecularly imprinted polymers as advanced nanomaterials for selective recognition of analytes in environmental, f…

2021

Abstract Samples with complex matrix analyzed during explanation of pathogenesis of various diseases and food or environmental monitoring request advanced analytical and instrumental devices. Among the materials used for described purposes, quantum (QDs) or carbon dots (CDs) layered by molecularly imprinted polymer (MIP) shells have gained widespread attention. Unique optical and physicochemical properties of QDs/CDs together with high MIPs selectivity make the QD/CD-MIP conjugates capable of adsorbing specific target molecules – such a binding event is then transduced as the optical signal of the response by the QDs/CDs. This review includes brief introduction on principles of imprinting p…

L’impronta del doppio: il movimento immobile

2014

L’attimo temporale rende la realtà dell’impronta materia della scansione ritmica, rappresentazione della forma, disegno del gesto. L’impronta è forma di un movimento congelato. L'articolo affronta uno studio sulla percezione del movimento nell'ambito della rappresentazione.
