Italian Households’ Material Deprivation: Multi-Objective Genetic Algorithm approach for categorical variables
No full textMaterial deprivation is a complex concept referring to the inability of
families to meet certain needs. Some indicators of material deprivation, included in
the EU portfolio, are collected by EU-SILC survey on households and individuals
through categorical variables. In this study, the large dataset provided by EU-SILC
survey collected in Italy in 2017, on a sample of 22,226 households is analysed. The
main goal is to identify clusters of Italian households to take into account the multiple
aspects of material deprivation conditions, including environmental ones. To that end,
a multi-objective genetic algorithm as a clustering technique for categorical data is
proposed. The results are compared with those obtained by applying a K-means
algorithm to latent variables scores
Cultural Participation and Social Inequality in the Digital Age: A Multilevel Cross-National Analysis in Europe
No full textCultural participation is considered as a necessary element of social equity, able to generate positive effects on individual opportunities and quality of life as a whole. Adopting a cross-national perspective, this study considers both traditional and new cultural practices deriving from the rise of new technologies, aiming at analyse how social inequality affects cultural participation in the European countries in the digital age. The main specific goals are the following: (1) elaboration of a synthetic index of Cultural Participation at European level; (2) identification of the determinants of participation at both individual and country level; (3) test of the interactions between some country features and individual characteristics, indicators of social differences, to verify their effects on cultural participation. The empirical analysis is based on 26,053 respondents aged 15 years and over, collected by the Special Eurobarometer survey n. 399 containing comparable data on cultural participation. To take into account country characteristics, some variables have been taken from other statistical sources (Eurostat). Data analysis resorted to Nonlinear Principal Component Analysis and multilevel regression models
Social networks feed the food supplements shadow market
Full text linkPurpose: The paper investigates the role of social networks in the millennials’ decision-making process of illegal and unnotified food supplements purchase. The connections and interactions that (co) produce information are studied with a holistic perspective of social sustainability as a development driver of business model innovation. Design/methodology/approach: An exploratory qualitative multiple analysis study was conducted in two consecutive phases. Data from 23 semi-structured individual interviews were collected, followed by a netnographic analysis of the Facebook virtual community. Findings: The results show that the decision-making process does not develop following the traditional sequence, as social networks modify the wellness meaning creation process and reduce risk perception. Moreover, social networks introduce the use of similar experiences of others and online information and emotional support on unethical and unhealthy behavior. Research limitations/implications: Due to the application to a social network, the results should be understood within this context. Future studies would benefit by expanding the target and the range of social networks explored. Practical implications: The official information quality control, as a prerogative of public and professional health stakeholders, and the medialization of medicalization, contribute to the conscious development of their wellness meanings and values. Originality/value: This work represents one of the first attempts to investigate resources integration through social networks in the pre-purchase decision-making process of unnotified and illegal food supplements. Unethical and unhealthy behavior develops through the interaction of actors, firms, influencers and individuals over social networks
Night at the museum. Technology enables visitor experiences
No full textPurpose of the paper: This paper aims to investigate how technology affects the cultural heritage (CH) experience and how it may configure a new service ecosystem, enabling resource integration, and leveraging resource liquefaction.
Methodology: A model with four dimensions of CH experience is proposed and empirically tested using structural equation modeling with data on 300 visitors to three heritage sites in Rome (Italy), which exhibit a high level of technology integration.
Results: Technology enables learning processes in the cultural heritage visit experience. The CH experience is configured as a service ecosystem and technology enables increases in resource integration, liquefaction, and density by operating both as an operant and operand resource.
Research limits: The study of technology from a service-dominant (S-D) logic perspective is nascent vis-a-vis framing the CH visit experience.
Practical implications: Technology acceptance is important for learning and positive perceptions of authenticity. A dynamic approach to the conceptualization of cultural supply structures is important.
Originality of the paper: This research advances both theory and practice, adding to existing discourses on CH from a broader perspective that includes CH as a potential part of a service ecosystem, highlighting the role of technology in designing and shaping resource integration. The paper, therefore, offers a novel perspective on CH in terms of value co-creation, highlighting the role of participating architecture for learning
Lo shopping conta? Il centro storico delle città d'arte come ambiente di shopping e il suo impatto sulla soddisfazione del turista
No full textNel più ampio quadro di riferimento del turismo urbano, un caso speciale è rappresentato da quel cluster di città noto come “città d’arte”. Queste sono definite dalla presenza di asset culturali – artistici identitari (es. Colosseo per Roma), che, soli, possono valere come attrattori preminenti, se non esclusivi, delle scelte di visita del turista urbano. Un sub cluster di queste, infine, è rappresentato dalle città Patrimonio Mondiale Unesco che si caratterizzano per l’elevato grado di notorietà mondiale e la rigidità imposta nella gestione degli asset culturali -artistici. Questi riconoscimenti e tutele offrono indiscutibili e importanti vantaggi in termini di posizionamento, conservazione, valorizzazione e visibilità, ma rischiano di irrigidire sia il ventaglio delle possibili aspettative pre viaggio dei turisti che la varietà di esperienze fruibili. Il tema del turismo urbano in Italia presenta degli elementi di peculiarità importanti. Innanzitutto la sua interpretazione pressoché coincidente con il turismo culturale e delle città d’arte. Questa circostanza costituisce, infatti, un significativo limite interpretativo ma anche gestionale del turismo nelle città. Il turista urbano ha uno spettro di motivazioni che includono anche quella culturale ma non si esauriscono con questa. Relegare il turismo delle città d’arte a turismo culturale significa focalizzarsi su un importante e, in questo momento prioritario mercato, senza, tuttavia, tener conto dei cambiamenti in corso e già avvenuti nella domanda mondiale di turismo urbano. Alcune delle conseguenze sono evidenti: dalla necessità di gestire emergenze di carico antropico, tutela e conservazione del patrimonio storico e artistico nei periodi di maggior afflusso, coincidenti con lo spopolamento di alcune aree o città (si pensi a Venezia), fino al tema diffuso e riguardante molti centri minori e piccole città d’arte dello spopolamento dei centri storici e conseguente degrado, che neanche il turismo è in grado di compensare. Il presente contributo intende analizzare la rilevanza dell’ambiente “centro storico” e della sua atmosfera nell’esperienza di shopping del turista. Lo scopo è individuare quali dimensioni e aspetti relativi, alla fruizione multidimensionale dello spazio possano essere valorizzati, secondo l’ottica di rigenerazione urbana basata sull’interazione sociale con lo spazio urbano che caratterizza il turista postmoderno
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
