Smart City nella prospettiva economico aziendale. Inquadramento teorico e implicazioni manageriali
No full textNegli ultimi decenni si è sviluppato un intenso e proficuo dibattito sulla smart city, ed è emerso un nucleo di conoscenze multidisciplinari, tuttora in evoluzione, e la diffusione di soluzioni efficaci per fronteggiare rilevanti problemi economico-sociali. Il presente lavoro propone una interpretazione in chiave economico-aziendale del fenomeno della smart city, i cui tratti peculiari sono stati ricercati nell’alveo degli studi economico-aziendali e dell’azienda pubblica in particolare. Dall’analisi è emerso come molti dei caratteri che qualificano tale organismo socioeconomico – quali la natura di sistema aperto, autonomo, dinamico e duraturo, la connaturata esposizione ai rischi e l’attuazione di piani e programmi per il raggiungimento dei fini istituzionali –, siano rintracciabili e risultino addirittura amplificati nel modello di smart city qui proposto. Ne deriva una caratterizzazione di smart city che migliora in funzione della capacità di soddisfare i bisogni della comunità di riferimento, che si rigenera nella ricerca continua dell’accrescimento del valore delle proprie risorse e dello sviluppo integrale delle persone che ne fanno parte, che rinforza la propria capacità di risposta agli shock esterni e rinsalda le relazioni e i legami collaborativi tra attori sociali in vista della creazione e diffusione di valore pubblico. L’elevata complessità tipica del modello smart city e le dinamiche socio-ambientali in atto segnalano l’esigenza di definire adeguati sistemi di misurazione della performance atti a supportare il processo decisionale della governance urbana, delineando per questa via un promettente ambito di ricerca per gli studi economico-aziendali nel prossimo futuro
Multistep high order interpolants of Runge-Kutta methods
No full textWe consider a p-order Runge-Kutta method K(i)(n) = f(x(n) + c(i)h, y(n) + hSIGMA(j=1)(nu)a(ij)K(j)(n)), i = 1,..., nu, y(n+1) = y(n) + hSIGMA(i = 1)(nu)b(i)K(i)(n)), for solving an initial-value problem for ordinary differential equations. The aim of this paper is to construct p-order interpolants by using the values furnished by the method on N successive intervals of integration. By using Lagrange interpolation one can obtain a p-order interpolant over p intervals, but we are interested in finding the minimum number of intervals needed to obtain this. We provide the conditions to be satisfied and we obtain an estimation of the number N. Some examples are given
Le tecnologie digitali a supporto dell’intelligenza urbana: l’evoluzione “data driven” delle città
No full textLe tecnologie digitali hanno ormai assunto un ruolo chiave nel migliorare “l’intelligenza” delle città e aumentare la “resilienza” delle loro comunità di fronte a fenomeni quali cambiamenti climatici, disuguaglianze economiche e sociali, disastri naturali, pandemie, ecc.
Alla luce di tali rischi ed alle sfide che dal loro fronteggiamento discendono, le città devono dotarsi di infrastrutture e strumenti tecnologici avanzati e potenziare quelle già esistenti al fine di monitorare l’evolversi dei fenomeni ambientali, sociali, economici, condividere e diffondere conoscenza e, ove necessario, intervenire tempestivamente per ridurre i rischi e/o gestire le emergenze in corso. Il presente lavoro esamina il legame tra “intelligenza urbana” e tecnologie emergenti, attraverso una disamina delle principali applicazioni di tali tecnologie a livello urbano
Impatti degli strumenti di e-government sui processi di co-produzione e sui rapporti di interazione fra Enti locali e cittadinanza. Il caso della piattaforma tecnologica ePart nel Comune di Udine.
No full textIn recent years, many legislative reforms have affected local authorities. In this context, the spread of open data technologies and e.government tools seems to allow for greater involvement of citizens in the management of public services. This research aims to study the impact of these new technologies on public service management and on relationships local authorities and citizens. Through a single case study, the effects of the ePart project (platform for the joint management of urban environments) on the Udine municipality have been analyzed. The research results show an improvement in the management of public services in terms of transparency and accountability, by intensifying the interaction with stakeholder involved

No full textMaking a Step Forward Towards Urban Resilience. The Contribution of Digital Innovation
No full textStarting from ‘wicked problem’theory as the landmark for framing disaster events in terms of policy issue for city governments, this chapter highlights the contribution provided by Big Data analytics and digital innovation in dealing with disaster risks. The research aims at answering the following question: what is the role that ‘smart technologies’ play in strengthening urban resilience to disaster risks
The 1908 earthquake of Messina. An accounting perspective on the city’s reconstruction between faith and Fascism
No full textThis article focuses on the 1923–1937 period when the rise of Benito Mussolini’s Fascist regime drove public works programmes. The 1908 earthquake almost destroyed Messina and, in the Fascist period Angelo Paino, the new Metropolitan Archbishop of Messina, fostered the reconstruction of the ecclesiastical heritage of the city and surrounding villages. Primary and secondary sources were collected and analysed to investigate the role of accounting and calculation practices in interpreting the urban reconstruction programme that the Fascist government actively supported. This research contributes to accounting history research adding the new reading of accounting, disasters and urban reconstruction, and highlighting the relations between the Fascist regime and the Catholic Church within an urban reconstruction programme following one of history’s major catastrophes. We obtained several findings, including an interpretation of the Fascist regime’s reconstruction of the city’s churches and key public buildings as an instrument of consensus among the Catholic

Exposure to static magnetic fields in NMR research laboratories
No full textTo obtain cumulative exposure of workers to static magnetic fields in research laboratories, isotropic magnetic flux density values generated by MR spectrometers were integrated over time. One need only to consider that in a non medical environment, exposure limits are regulated only by international guidelines and by good practice, while in MR diagnostic environment there is a proper legislation. In this paper, the AA also introduced a weighting function, incorporating the international guidelines limits, and tested it with the Italian legislation existing for medical workers. The results were stored on a personal dose card, in order to evaluate the daily exposure of the worker and to better study the long term effects to static magnetic fields
Blockchain and art market: resistance or adoption?
No full textBlockchain technology is currently stimulating a broader process of social and industrial transformation impacting several potential areas of adoption (e.g. transactions, tracking and tracing solutions, authenticity, etc ...). The acceptance of this technology represents a major challenge for the art ecosystem. The literature around relations and applications of blockchain in the art market is fragmented and fails to provide an understanding of the current/potential opportunities of this application. This paper explores how blockchain is being adopted in the art sector. By using a perspective of mobilizing organizational and institutional field theory, this study performs an explorative qualitative analysis based on semi-structured interviews with 15 experts from the art market. The findings underline the complexity of effective implementation of this technology, the contradictory positions regarding the benefits and business opportunities it offers, as well as the market players’ resistance to change and trust. The theoretical and practical implications are also discusse
