The value proposition of food delivery apps from the perspective of theory of consumption value
2021
Purpose The theory of consumption values (TCV) has successfully explained much consumer choice behavior, but few studies have investigated the values that drive food-delivery application (FDA) use. This study aims to bridge this gap by extending the TCV to the FDA context to examine food consumption-related values and interpreting and rechristening generic consumption values to adapt the TCV to the FDA context. Design/methodology/approach An explorative mixed-method research approach was taken to conduct focus group discussions with 20 target users to develop the questionnaire and then administer it for a cross-sectional survey (pen and pencil) to FDA users aged 22–65 years; 423 complete r…
Gradient Scheduling Algorithm for Fair Delay Guarantee in Logarithmic Pricing Scenario
2008
In this paper we propose a packet scheduling scheme for ensuring delay as a Quality of Service (QoS) requirement. For customers, fair service is given while optimizing revenue of the network service provider. Gradient type algorithm for updating the weights of a packet scheduler is derived from a revenue-based optimization problem in the logarithmic pricing scenario. Algorithm is simple to implement. We compared algorithm with optimal brute-force method. The weight updating procedure is independent on the assumption of the connection's statistical behavior, and therefore it is robust against erroneous estimates of statistics.
Introduction to ICT Enabled Services Minitrack
2015
The purpose of the minitrack is to draw researchers’ attention to ICT Enabled Services for both Consumers and Enterprises. It provides a discussion forum for researchers interested in fostering a service-based approach to these areas as well as an opportunity to present and debate both design and theory-based solutions to the problems facing industry in the deployment of ICT enabled services [1-4]. In a broad sense, ICT enabled services can be defined as [1]: “..systems that enable value co-creation through the development and implementation of information and communication technology enabled processes that integrate system value propositions with customer value drivers.”
Exploring End-User Reactions to Variations in the Value Proposition of Value Services
2009
Value services are most often innovations where endusers have little or no experience from using the service. Designing business models for such services is a challenging task including the design of value propositions that are perceived and interpreted through end-users’ complex value assessments. This study presents the results from a study of end-user value assessments of value proposition variations for two value services – mobile VoIP and multi play services. The study suggests a method for investigating end-user reactions to value proposition variations and presents the effects of these variations on attribute perceptions and value drivers. The main contribution of the study is method…
Current Software-as-a-Service Business Models: Evidence from Finland
2012
This paper characterizes the business models of Software-as-a-Service (SaaS) firms based on their value proposition, customer segments, revenue streams, and customer relationship, and analyzes interconnections of these business model elements. The target set of 163 Finnish SaaS and ASP firms was first compared to other software firms and then clustered into four clusters based on indicator data of their business model elements. The comparison reveals that the SaaS and ASP firms have smaller customer and transaction sizes than software firms in general. The resulting classification reveals two different configurations, a pure-play SaaS model and an enterprise SaaS model, and the typical fact…
Presentazione degli scritti scientifici inseriti nel cd
2013
Il prof. Giovanni Fierotti durante la sua attività accademica ha profuso un grande impegno nell’affermazione della Pedologia e delle Valutazioni territoriali, oggi Pedologia Applicata, finalizzata all’uso migliore dei suoli. Ha formato molti professionisti nel campo della docenza, scientifico e tecnico. Molti, oggi hanno, le leve del potere (come diceva sempre nell’introduzione al corso di “Classificazione Agronomica e Cartografia dei Suoli”. Nonostante lo sviluppo in Sicilia di una scuola di Pedologia a partire dagli anni sessanta (voluta dal prof. Ballatore) ed, a partire dagli anni novanta, di un servizio di Pedologia (presso l’Assessorato Agricoltura e Foreste di allora) l’informazione …
A strategy for the identification of building structures under base excitations
2008
In this paper the evolution of a time domain dynamic identification technique based on a statistical moment approach is presented. This technique is usable in the case of structures under base random excitations in the linear state and in the non linear one. By applying Itoˆ stochastic calculus special algebraic equations can be obtained depending on the statistical moments of the response of the system to be identified. Such equations can be used for the dynamic identification of the mechanical parameters and of the input. The above equations, differently from many techniques in the literature, show the possibility to obtain the identification of the dissipation characteristics independent…
Dynamical identification of building structures: new strategies

Giuseppe Samonà e la “spina dorsale” di Gibellina Nuova
2020
Nel 1970 Giuseppe Samonà coordina il gruppo di progettazione formato da Vittorio Gregotti, Gianni Pirrone e Alberto Samonà per il Progetto del Centro civico, commerciale e culturale di Gibellina Nuova. Del piano è realizzato il municipio e poi, rielaborato e in altro luogo, il teatro. I monumenti, fondati su un asse pedonale in quota connesso a un suolo artificiale articolato, esprimono l’unità architettura – urbanistica e anticipano, per certi versi, una riflessione successiva del Direttore dello IUAV sulla dialettica fra urbano e rurale.
Proporzioni delle statue. Analisi e cenni storici
2007
Lo studio e l’analisi della geometria e delle proporzioni del gruppo scultoreo monumentale in onore a Filippo IV, si sono effettuati su due sculture a tuttotondo - facenti parte di un gruppo di otto sculture collocate sulla balaustrata - e su un pannello scultoreo ad altorilievo, uno dei quattro situati sui lati del nucleo centrale, all’apice del quale s’innalza la statua, ora, di Filippo V. Le statue del gruppo scultoreo, disposte in un’armoniosa composizione, presentano elementi tipicamente rinascimentali introdotti in Sicilia dai maestri marmorai e lapicidi nel XVI secolo sino a tutto il primo trentennio del secolo successivo.
