No full textLo stenditoio del signor Girasole, attribuzione dei punteggi: messa a fuoco di alcune difficoltà dei correttori
No full textAbstract: Ci siamo interrogati a proposito dell’influenza della prtica del Rally Matematico Transalpino sulla valutazione, organizzando un’attività sperimentale, illustrate nel seguito. Abbiamo cercato di chiarire il rapporto tra valutazione ed assegnazione del punteggio, riassumendo alcuni aspetti fondamentali della prima e paragonandola con la seconda che è specifica del RMT
Who is innovating? An exploratory research of digital technologies diffusion in retail industry
Full text linkTo date, the diffusion of digital technologies is rapidly increasingly in the physical stores as prompt by the continuous advancements in technology and consumers' expectation of new technologies. To the authors' knowledge, the evaluation of the extent to which retailers are meeting this challenge is still at an early stage. Thus, the aim of this study is to investigate the actual level of diffusion of these technologies to understand retailers' effective response. In particular, drawing upon Rogers’ Theory of Innovation Diffusion (1962), the present study is based on the direct observation of 208 stores located in Oxford Street (between Marble Arch and Tottenham Court Road tube stations), London, UK in October and November 2017. Results provide an overview of the actual innovation adoption strategies in terms of innovation diffusion and the main digital technologies adopted by different retail categories considering size and store typology. Finally, the Retailing Innovation Market framework is proposed as a combination between actual technological offer and retailer demand of innovation technology, while impact for scholars and practitioners is further discussed.</p
Privacy concerns and justice perceptions with the disclosure of biometric versus behavioral data for personalized pricing tell me who you are, I'll tell you how much you pay. Consumers’ fairness and privacy perceptions with personalized pricing
Full text linkThis research investigates whether consumers express different levels of store patronage intention and expected amount of discount depending on the type of data they have to disclose to obtain a personalized price. Findings from two experiments-manipulating the type of data along with the type of incentive (Study 1) and the level of effort (Study 2)-reveal that behavioral (vs. biometric) data make customers perceive the outcome of the price personalization more equitable, thus lowering the privacy concern, and enhancing their sense of entitlement to receiving a benefit from the retailer. The impact of the type of data on perceptions of distributive justice changes as a function of the type of incentive provided to customers (Study 1) and the level of effort required to see the personalized price (Study 2). The collection of biometric data should be counterbalanced by a higher amount of personalized discount to lower consumers' privacy concerns
I, Chatbot! The Impact of Anthropomorphism and Gaze Direction on Willingness to Disclose Personal Information and Behavioral Intentions:
Full text linkThe present research focuses on the interplay between two common features of the customer service chatbot experience: gaze direction and anthropomorphism. Although the dominant approach in marketing theory and practice is to make chatbots as human-like as possible, the current study, built on the humanness-value-loyalty (HVL) model, addresses the chain of effects through which chatbots’ nonverbal behaviors affect customers’ willingness to disclose personal information and purchase intentions. By means of two experiments that adopt a real chatbot in a simulated shopping environment (i.e., car rental and travel insurance), the present work allows us to understand how to reduce individuals’ tendency to see conversational agents as less knowledgeable and empathetic compared to humans. The results show that warmth perceptions are affected by gaze direction, whereas competence perceptions are affected by anthropomorphism. Warmth and competence perceptions are found to be key drivers of consumers’ skepticism toward the chatbot, which, in turn, affects consumers’ trust toward the service provider hosting the chatbot, ultimately leading consumers to be more willing to disclose their personal information and to repatronize the e-tailer in the future. Building on the theory of mind, our results show that perceiving competence from a chatbot makes individuals less skeptical as long as they feel they are good at detecting others’ ultimate intentions
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
Probability-density risk-maps for tourism during emergencies
Full text linkIn the following, we show how to develop a probability-density risk-map of COVID-19 contagion for London. London was chosen as it is one of the main global destinations before the pandemic, with approximately 16.38 million overseas tourists in 2019 alone (Statista 2020). We map the main tourist attractions scattered across the city and each area's risk level, square-foot by square-foot. Then, we provide examples of how prospective tourists react to the map
