La percezione della web atmosphere tra i visitatori del centro commerciale
No full textIl paper analizza le variabili della website atmosphere utilizzabili nella progettazione del sito web di un centro commerciale ed approfondisce l’importanza dei diversi attributi assumendo la prospettiva del potenziale utente ed i suoi atteggiamenti nei confronti del format. Il lavoro si basa su un’indagine empirica, condotta tramite questionario, rivolta ad un campione di 438 studenti universitari, di età compresa tra i 18 e 30 anni. L'indagine rivela l’esistenza di atteggiamenti diversi degli utenti nei confronti della web atmosphere a seconda del comportamento di shopping prevalente ed un’attenzione diffusa verso gli attributi social del sito web che favoriscono l’interattività. Investimenti online mirati a rafforzare la presenza e le promozioni sui social network ed altri strumenti di comunicazione interattiva (forum, chat...) potrebbero costituire efficaci leve per incrementare l’attrattività del sito web e rafforzare i processi di fidelizzazione
Geometry of the matching distance for 2D filtering functions
Full text linkIn this paper we exploit the concept of extended Pareto grid to study the geometric properties of the matching distance for R^2-valued regular functions defined on a closed Riemannian manifold. In particular, we prove that in this case the matching distance is realised either at special values or at values corresponding to vertical, horizontal or slope 1 lines
A topological model for partial equivariance in deep learning and data analysis
Full text linkIn this article, we propose a topological model to encode partial equivariance in neural networks. To this end, we introduce a class of operators, called P-GENEOs, that change data expressed by measurements, respecting the action of certain sets of transformations, in a non-expansive way. If the set of transformations acting is a group, we obtain the so-called GENEOs. We then study the spaces of measurements, whose domains are subjected to the action of certain self-maps and the space of P-GENEOs between these spaces. We define pseudo-metrics on them and show some properties of the resulting spaces. In particular, we show how such spaces have convenient approximation and convexity properties
Feature-based automatic 3D registration for cultural heritage applications
No full textThis paper presents a review of the state-of-the-art techniques in the field of 3D invariant features for the automatic registration of point clouds and 3D meshes. The paper proposes also a multi-stage 3D registration pipeline implemented using the PCL libraries. Experiments are carried out on datasets related to heritage scenarios and addressing large-scale outdoor data acquisitions as well as small objects
Web atmospherics as drivers of shopping centres' customer loyalty
No full textPurpose
The purpose of this paper is to analyse whether and how the website atmosphere (WA) of a shopping centre affects the behavioural loyalty of customers towards physical shopping centres. A mediating variable – individual shopper motivation – is considered in assessing this relationship.
Design/methodology/approach
The research hypotheses were tested using a partial least squares – path modelling approach to structural equation modelling on a sample population of 438 individuals.
Findings
Online atmospherics, particularly concerning the social/relational attributes of the WA, positively affect the behavioural loyalty of customers towards physical shopping centres. Moreover, recreational motivations strengthen this relationship more than functional motivations do.
Research limitations/implications
The sample investigated is limited with regard to diversity, age and gender. Future research can use a more representative sample to improve the findings’ relevance and generalisation. Also the development of a scale of measures for the shopping centre customers’ motivations is worthy of interest in future studies.
Practical implications
Recognising the importance of web atmospherics’ significant impact on customer loyalty should encourage shopping centre managers to develop effective website and online communication programmes.
Originality/value
Extant studies have paid little attention to the relationship between WA and customer loyalty to the physical shopping centre. This study investigates this relationship, combining the online and offline perspective into an overall research approach. Moreover, it contributes to the research on website management in the shopping centre context by providing a comprehensive analysis of WA, whereas previous studies have mainly focussed on one or a few atmospherics
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
