Evaluation of perception to different stimuli by cognitive and emotional reaction for neuromarketing application
Full text linkThe antismoking Public Service Announcements (PSAs) have been designed with the aim of successfully reduce smoking in people and to prevent the beginning of this dangerous habit in non-smokers. PSAs success is reflected by the decreasing of smoking rate in several European countries. However, the EU’s smoking rate among adults is falling too slowly to meet the EU government’s goal. This could be due to ineffective nature of the delivered antismoking messages and/or to particular communication styles possibly causing the “boomerang effect” on smokers, eliciting in them the urge to smoke. Furthermore, tobacco consumption is highly influenced by socioeconomic factors, affecting mostly low- and middle-income countries, but also vulnerable populations within high income countries, and finally the young population as being at higher risk of developing tobacco addiction. Additionally, smoking causes health inequality between gender and age groups, also significantly elevating the preventable morbidity and premature mortality worldwide. Consequently, it clearly appears the need to design antismoking campaigns that could be effective regardless of socioeconomical variable.
When effective, PSAs are of substantial benefit to public welfare, but the lack of reliable, quantitative and objective tools of evaluating advertising effectiveness before the dissemination is one of the key impediments to the obtainment of better PSA outcomes.
Basing on these considerations, it appears useful to apply Neuroscientific techniques to the PSAs testing in order to:
investigate the existence of neurophysiological features associated to the perception of Effective, Ineffective and Awarded PSAs
assess whether the socio-economic variables can influence the perception of antismoking PSAs
These are the experimental questions that my PhD research activity tried to answer, with the aim to understand if it would be possible to develop efficient and cost-effective antismoking campaigns, valid for the different EU countries

No full textGender and Age Related Effects While Watching TV Advertisements: An EEG Study
Full text linkThe aim of the present paper is to show how the variation of the EEG frontal cortical asymmetry is related to the general appreciation perceived during the observation of TV advertisements, in particular considering the influence of the gender and age on it. In particular, we investigated the influence of the gender on the perception of a car advertisement (Experiment 1) and the influence of the factor age on a chewing gum commercial (Experiment 2). Experiment 1 results showed statistically significant higher approach values for the men group throughout the commercial. Results from Experiment 2 showed significant lower values by older adults for the spot, containing scenes not very enjoyed by them. In both studies, there was no statistical significant difference in the scene
relative to the product offering between the experimental populations, suggesting the absence in our study of a bias towards the specific product in the evaluated populations. These evidences state the importance of the creativity in advertising, in order to attract the target population
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

No full textVariations 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
