‘Interesting but scary’ : Customers' perceived value of MyData
2022
Digitalisation has facilitated saving data in various warehouses. While Big Data is a new form of capital that is often considered an asset for organisations, the potential value of data to customers has seldom been addressed. This chapter discusses MyData (personified and personalised data) and aims to increase our understanding of its benefits and the value created when customers use their own data. The empirical data for this paper were collected from customers of a large retail organisation that adopted the practice of sharing data with customers. This study has found that value accruing from customer’s shopping data is multifaceted and can be either positive (creating value) or negativ…
A Customer Perspective on Omnichannel Customer Journey and Channel Usage : A Qualitative Study
2022
This qualitative study investigates customer behavior during the omnichannel customer journey. The study aims to increase the understanding of omnichannel service environments from a customer-centric point of view. The data was collected by interviewing 10 young adults (from 26 to 30 years old) who had bought a Finnish clothing brand (R-Collection) product via a digital or a physical channel. The research interviews dealt with the interviewees' experiences and channel behavior during their shopping journeys. Our results reflect the multidimensional nature of the omnichannel customer journey and give interesting insights into the usage of digital channels and technologies for clothing shoppi…
Digitaalisten kuvaväärennösten tunnistaminen JPEG-pakkausta hyödyntäen
2010
Digitaalisten valokuvien muokkaamisesta on tullut hyvin helppoa ja yleistä, mikä on nostanut esille huolen valokuvien uskottavuudesta. Ongelman ratkaisuksi on esitetty erilaisia tekniikoita, joilla valokuvien aitoutta voidaan arvioida. Tarkastelen tässä tutkielmassa niin sanottuja passiivisia tekniikoita, jotka eivät edellytä kuvasta minkäänlaista ennakkotietoa, kuten vesileimaa. Vertailen viittä tällaista tekniikkaa laatimani neljä kohtaa käsittävän kriteeristön pohjalta. Vertailtavia ominaisuuksia ovat tarkkuus, tunnistetut muokkaustyypit, rajoitukset sekä vakaus vastatoimia vastaan. Vertailu osoittaa, että eräs merkittävimmistä tekniikoiden ongelmista on niiden huono toleranssi kuvan häv…
Il percorso (incerto) della c.d. web tax italiana tra modelli internazionali ed eurounitari di tassazione della digital economy
2019
L’articolo analizza gli aspetti essenziali dell’evoluzione delle strategie di tassazione delle imprese della digital economy, tanto a livello internazionale, quanto a livello eurounitario, per concludere, poi, con un’analisi dell’art. 1, commi 35 e segg., della Legge 30 dicembre 2018 n. 145 (legge di bilancio 2019), che ha introdotto, nel nostro sistema una vera e propria imposta sulle imprese che operano nel settore digitale, denominata “imposta sui servizi digitali” (ISD). Si osserva, a riguardo, che nel comparto della digital economy, quanto all’aspetto della tassazione, è possibile individuare tre diversi approcci. Il primo attribuisce particolare rilievo alla c.d. “presenza economica s…
Comunicación local y nuevos formatos periodísticos en Internet: cibermedios, confidenciales y weblogs
2008
El libro que aquí presentamos es el resultado más reciente de un esfuerzo colectivo que comenzó con la creación de un grupo de investigación, apoyado por la Universidad de Valencia, en torno al análisis de los medios digitales valencianos. Se trataba (y sigue tratándose, en buena medida) de un ámbito de investigación casi inexplorado. Pero desde un principio consideramos que su interés no sólo radicaba en su carácter ignoto, sino en la constatación de que el ecosistema comunicativo valenciano, y más en general el ámbito de la comunicación local vehiculada a través de Internet, había adquirido ya una madurez suficiente como para constituirse en ámbito de estudio por sí mismo, sin apoyarse en…
Innovazione sociale: condivisione ed inclusione delle scelte nell’erogazione dei servizi pubblici (Decisioni a rete ed in rete).
2018
Il contributo si propone di scandagliare la tensione, cui si trova la pubblica amministrazione, tra esigenze di semplificazione e ricerca di forme di partecipazione inclusive. Partendo da una disamina del contesto attuale, dei problemi collegati al digital divide, si analizza la portata del rapporto tra innovazione sociale e welfare digitale nella pubblica amministrazione. Si approfondisce altresì il tema delle ICT come strumenti di benessere sociale, anche in funzione di trasparenza. Nuovi modelli di condivisione delle scelte: “decisioni a rete e in rete”.
Mercato digitale e sistema delle successioni mortis causa
2022
The work aims to examine the curvature impressed by the current order of the market and of the "algorithmic" society, centered on social network platforms, on principles and categories of classical hereditary law, putting the system of mortis causa succession into reaction with the matter of relationships and personal rights developed on the web, marked by the changes that shake the European and internal legal framework. The study is organized according to a tripartite scheme, which distinguishes the succession in contracts for the supply of digital services, from the transmission of rights on user-generated content and on the personal data of the deceased. To then keep a unity in the const…
Estimation of wind velocity over a complex terrain using the Generalized Mapping Regressor
2010
Abstract Wind energy evaluation is an important goal in the conversion of energy systems to more environmentally friendly solutions. In this paper, we present a novel approach to wind speed spatial estimation on the isle of Sicily (Italy): an incremental self-organizing neural network (Generalized Mapping Regressor – GMR) is coupled with exploratory data analysis techniques in order to obtain a map of the spatial distribution of the average wind speed over the entire region. First, the topographic surface of the island was modelled using two different neural techniques and by exploiting the information extracted from a digital elevation model of the region. Then, GMR was used for automatic …
Fractional calculus approach for the representation of power spectral densities and correlation functions in wind engineering
2010
The paper deals with the digital simulation of wind velocity samples by Fractional Spectral Moment function. It is shown that such a function represents a third useful way to characterize a stationary Gaussian stochastic process, alongside the power spectral density and the correlation function. The method is applied to wind velocity fields whose power spectra is given by the Kaimal’s, the Davenport’s and the Solari’s representation. It is shown that by constructing a digital filter whose coefficients are the fractional spectral moments, it is possible to simulate samples of the target process as superposition of Riesz fractional derivatives of Gaussian white noise processes.
Discurso y participación política en Plaza Podemos
2017
El uso de Internet y de sus posibilidades de persuasión e interacción ha convertido a los ciudadanos en actores políticos. Internet y las nuevas tecnologías no son un medio más, sino el reflejo organizativo de la nueva cultura política del ciberactivismo. Esta investigación ofrece datos sobre las características que tiene esa interacción dentro de un proceso de movilización política. Se ha empleado la herramienta de organización subreddit Plaza Podemos para descubrir si su uso expansivo se muestra eficaz para los foros virtuales del debate político comunitario. Se han obtenido datos de 100 hilos discursivos publicados en Plaza Podemos entre el 23 de abril y el 30 de septiembre de 2015. Se c…
