How can I signal my quality to emerge from the crowd? A study in the crowdsourcing context
2022
Crowdsourcing contests are characterized by an intensive level of competition because of the extensive number of solvers that voluntarily self-select to participate in such contests. This study aims at understanding how solvers can signal their quality attributes through the community functionalities, i.e. the online profile and the discussion blog of the crowdsourcing platform, to improve their chances of winning crowdsourcing contests. Drawing on signaling theory, we hypothesize that signaling their skills and capabilities by crafting profiles rich in personal and professional information and by participating actively within the discussion blog by posting and commenting, solvers can influ…
A heuristic method for estimating attribute importance by measuring choice time in a ranking task
2012
The evaluation of a product or service in terms of its attributes has been broadly studied in marketing, management and decision sciences. However, methods for finding important attributes have theoretical and practical limitations. The former are related to the selection of the most appropriate model; the latter are due to large number of variables that affect the specific experimental context. This study aims to present a new methodology that captures attribute preferences from a respondent and in particular, by using the choice time in a ranking task, it allows to indirectly obtain the importance weights for several tested attributes through a simple, fast and inexpensive procedure.

Crowdfunding as a tool to support sustainability‐oriented initiatives: Preliminary insights into the role of product/service attributes
2019
A common goal of current research seems to uncover whether crowdfunding (CF) could be considered an effective way to support sustainability-oriented initiatives in securing funding, due to diverging results emerging from literature. We claim that the objective of proving whether CF may benefit sustainability-oriented initiatives could be misplaced; rather, we deem more fruitful to understand how critical are some attributes of products/services pursued within CF campaigns to benefiting sustainability-oriented initiatives and increasing their odds of success in CF. We focus on food-related projects as in this sector, sustainability issues apply more than to any other human activities and con…
Understanding consumer demand for sustainable beef production in rural communities
2015
In the past two decades, due to the series of crises within the agro-food system, such as BSE, dioxin, and foot and mouth disease, consumer demand for sustainable production has considerably grown in European society. Consumers seem to frame food quality in terms of social and environmental aspects of productions, which may be recognized through a certification labelling or through a system of food quality criteria that give rise to conventions of quality. The aim of our study was to understand how food quality and labelling are assessed by rural population in Southern Italy. Local beef production with sustainable voluntary certification was the focus of our empirical strategy. Our decision…
Conventions of Quality in Consumer Preference toward Local Honey in Southern Italy
2016
During the last few decades consumer demand for local foods has increased around the world, particularly in the USA and Europe. Such consumer trend also contributes to redefine a new alternative geography of food; in which local foods are perceived to be of better quality and safer. Moreover, consumers frame local food quality not only in terms of general attributes, such as taste and price, but also in terms of more subjective attributes closely linked to social and environmental aspects of products. These attributes are recognised by consumers as a range of socially constructed food quality criteria, which play an important role in the creation of information about quality and consumer de…
Multiresolution Analysis for Irregular Meshes
2003
International audience; The concept of multiresolution analysis applied to irregular meshes has become more and more important. Previous contributions proposed a variety of methods using simplification and/or subdivision algorithms to build a mesh pyramid. In this paper, we propose a multiresolution analysis framework for irregular meshes with attributes. Our framework is based on simplification and subdivision algorithms to build a mesh pyramid. We introduce a surface relaxation operator that allows to build a non-uniform subdivision for a low computational cost. Furthermore, we generalize the relaxationoperator to attributes such as color, texture, temperature, etc. The attribute analysis…
Sustainable Renovation Framework: Introducing three levels of Integrated Design Process Implementation and Evaluation
2017
Future sustainable building renovation is a balance between the economic and environmental impacts related to the desired social activities facilitated by the renovated building. A review of recent research has revealed that the present efforts on sustainable objectives fulfilment in renovation projects are not sufficient. This paper investigates processes and frameworks in building renovation. It aims to deal with simplification of the existing complexity due to involvement of various types of stakeholders, sustainability criteria and potential renovation technologies in design process. Moreover, it facilitates understanding of the design process implementation through identification of th…
Attitudes and perceptions of faculty members in the process adopting innovation: The OpenCourseWare initiative at the University of Valencia, Spain
2014
The OpenCourseWare project, an open learning resource repository, was established at the University of Valencia between 2008 and2009. It initially consisted of only 10 subjects, none of which was in the field of Health Sciences. The objective of this research was toinvestigate the attitudes and perceptions of faculty members in the field of Health Sciences with regard to the project to identify strategies to increase its use and expand its coverage. We applied Rogers’ innovation-diffusion theory along with a qualitative approach using theoretical sampling, semi-structured interviews and open coding. The results indicate the existence of two categories of faculty members. In the first group,…
Correction: Mechanical properties of provisional dental materials: A systematic review and meta-analysis.
2018
Provisional restorations represent an important phase during the rehabilitation process, knowledge of the mechanical properties of the available materials allows us to predict their clinical performance. At present, there is no systematic review, which supports the clinicians’ criteria, in the selection of a specific material over another for a particular clinical situation. The purpose of this systematic review and meta-analysis was to assess and compare the mechanical properties of dimethacrylates and monomethacrylates used in fabricating direct provisional restorations, in terms of flexural strength, fracture toughness and hardness. This review followed the PRISMA guidelines. The searche…
Non solo Platone. Il primato dell'oralità nel retore Alcidamante
2020
Il saggio è dedicato all’orazione Sugli autori dei discorsi scritti o sui sofisti, attribuita al retore Alcidamante, discepolo di Gorgia e attivo in Atene tra il 410 e il 365 a.C. Argomento dell’orazione è il serrato confronto tra due differenti modalità oratorie, l’autoschediazein (“parlare a braccio”) — cui Alcidamente accorda una netta superiorità — e il "gegrammena legein (“pronunciare discorsi scritti”). L’interesse di questo testo (databile con buona approssimazione intorno al 390 a. C) consiste essenzialmente nel rappresentare un punto di vista specificamente retorico sulla questione delle differenze tra scritto e parlato. Nonostante alcune significative convergenze con il ben più ce…
