Influenceri kā komunikācijas instruments Latvijas banku komunikācijā
2020
Darba ‘’Influenceri kā komunikācijas instruments Latvijas banku komunikācijā’’ galvenais mērķis ir noskaidrot Latvijas banku praksi, izmantojot influencerus savās sabiedrisko attiecību komunikācijas aktivitātēs, kā arī noskaidrot galvenos iemeslus, kāpēc kādai bankas komunikācijas aktivitātei tiek izmantots tieši šis influenceris un tiek uzskatīts, ka tas ir vislabākais komunikācijas kanāls, lai komunikācija izdotos. Darba pētnieciskā problēma ir noskaidrot, kādi ir galvenie iemesli, kādēļ influenceri tiek piesaistīti banku komunikācijai. Darba teorētiskā daļa balstās uz sabiedrisko attiecību un inflenceru jēdziena izskaidrošanu, sabiedrisko attiecību instrumentu apskatīšana, komunikācijas …
Mapping electron-beam-injected trapped charge with scattering scanning near-field optical microscopy.
2016
Scattering scanning near-field optical microscopy (s-SNOM) has been demonstrated as a valuable tool for mapping the optical and optoelectronic properties of materials with nanoscale resolution. Here we report experimental evidence that trapped electric charges injected by an electron beam at the surface of dielectric samples affect the sample-dipole interaction, which has direct impact on the s-SNOM image content. Nanoscale mapping of the surface trapped charge holds significant potential for the precise tailoring of the electrostatic properties of dielectric and semiconductive samples, such as hydroxyapatite, which has particular importance with respect to biomedical applications. The meth…
Recupero di un raro banco ottico del Melloni costruito nella Palermo della “belle époque”
2016
In questo articolo discuteremo del recupero di uno strumento scientifico di particolare interesse storico-didattico appartenente alla Collezione del Liceo Classico Statale “Umberto I” di Palermo: un raro banco ottico del Melloni costruito alla fine del 1800 nella Palermo della “belle époque” dal “macchinista” Filippo Caliri. Nell’articolo discuteremo gli aspetti tecnici degli interventi conservativi effettuati. In the article we will report on the recovery of a Melloni’s optical bench built at the end of 1800 by the “macchinista” Filippo Caliri in the “belle époque” of Palermo. A scientific instrument of particular historical and didactic interest belonging to the collection of Liceo Classi…
Exploring Historical Scientific Instruments by Using Mobile Media Devices
2022
We describe an educational activity that can be completed with mobile media devices in order to understand the working principle of a pair of tuning forks, from the Historical Collection of Physics Instruments of the University of Palermo, and how they were used to explain acoustic interference and beats with the Lissajous optical method. This approach can be used with any tuning fork and it is a valuable teaching strategy that does not require specific laboratory equipment.
ANCORA SULLA REVISIONE NEL CASO CONTRADA: LE OSSERVAZIONI DELLA PROCURA GENERALE PRESSO LA CORTE DI CASSAZIONE

L’importanza dei prerequisiti e dello screening precoce nella scuola dell’infanzia
2016
Questo contributo si propone di sottolineare l’importanza di alcune competenze cognitive, detti prerequisiti, che sono implicate nell’acquisizione delle abilità di lettura e scrittura come ad esempio: la conoscenza dell’alfabeto; la consapevolezza fonologica; la denominazione rapida automatica (RAN); la memoria fonologica e la processazione visiva. Numerose ricerche, anche internazionali, mostrano l’importanza dell’esercizio di tali abilità all’interno della scuola dell’infanzia anche ai fini della prevenzione dello sviluppo di difficoltà di apprendimento e/o di veri e propri disturbi nella successiva carriera accademica del bambino. Inoltre, la realizzazione di interventi didattici mirati …
Mūzikas instrumentu veikala interjera dizaina izveides specifika
2016
Diplomdarbā “Mūzikas instrumentu veikala interjera dizaina izveides specifika” autors izpētīja mūzikas instrumentu veikalu interjeru Latvijā. Galvenā uzmanība tika vērsta uz to, kāds ir to funkcionālais iekārtojums un kā vajadzētu iekārtot veikala telpas, lai pilnvērtīgi spētu nodrošināt pareizu instrumentu eksponēšanu un testēšanu. Tēmas izvēlē diplomdarba autoru ietekmēja esošo mazumtirdzniecības mūzikas veikalu Latvijā telpu iekārtojums, preču izvietojums un kopējais telpu dizaina modelis. Ar šo pētījumu diplomdarba autors vēlējās izzināt, kādi ir galvenie kritēriji izvēloties un realizējot noteiktu dizaina konceptu iekārtojot konkrētu mūzikas instrumentu veikalu. Diplomdarba autors uzsk…
Creating Digital Musical Instruments With and for Children: Including Vocal Sketching as a Method for Engaging in Codesign
2020
International audience; A class of master of science students and a group of preschool children codesigned new digital musical instruments based on workshop interviews involving vocal sketching, a method for imitating and portraying sounds. The aim of the study was to explore how the students and children would approach vocal sketching as one of several design methods. The children described musical instruments to the students using vocal sketching and other modalities (verbal, drawing, gestures). The resulting instruments built by the students were showcased at the Swedish Museum of Performing Arts in Stockholm. Although all the children tried vocal sketching during preparatory tasks, few …
Shaded-Mask Filtering for Extended Depth-of-Field Microscopy
2013
This paper proposes a new spatial filtering approach for increasing the depth-of-field (DOF) of imaging systems, which is very useful for obtaining sharp images for a wide range of axial positions of the object. Many different techniques have been reported to increase the depth of field. However the main advantage in our method is its simplicity, since we propose the use of purely absorbing beam-shaping elements, which allows a high focal depth with a minimum modification of the optical architecture. In the filter design, we have used the analogy between the axial behavior of a system with spherical aberration and the transverse impulse response of a 1D defocused system. This allowed us the…
Calibration of optimal execution of financial transactions in the presence of transient market impact
2012
Trading large volumes of a financial asset in order driven markets requires the use of algorithmic execution dividing the volume in many transactions in order to minimize costs due to market impact. A proper design of an optimal execution strategy strongly depends on a careful modeling of market impact, i.e. how the price reacts to trades. In this paper we consider a recently introduced market impact model (Bouchaud et al., 2004), which has the property of describing both the volume and the temporal dependence of price change due to trading. We show how this model can be used to describe price impact also in aggregated trade time or in real time. We then solve analytically and calibrate wit…
