Effects of mode, consonance, and register in visual and word-evaluation affective priming experiments
No full textAn affective cross-modal priming paradigm was used in three experiments to test the effects of mode, consonance, and register in picture-evaluation and word-evaluation tasks. In experiment 1, participants heard major mode/minor mode, high-register/low-register chords (three tones) as primes and then they had to categorize a happy' or sad' word as a target. Participants evaluated target words faster if the words were preceded by a similarly valenced chord as opposed to affectively incongruent chord-word pairs. In experiments 2 and 3, target words were replaced by target affective pictures. In experiment 2, the primes were consonant/dissonant, high register/low-register chords. Register influenced picture evaluation whereas consonance was not effective for the affective priming. In experiment 3, the primes were major mode/minor mode, high-register/low-register chords. Register induced a faster recognition of targets while mode was not effective. Register is suggested to be a more powerful structural aspect of music than mode or consonance in influencing ongoing cognitive activities
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
Charting Dark Matter interactions
Full text linkThe nature of Dark Matter (DM) is one of the most compelling problems in Fundamental Physics.It is a well established fact that the Standard Model (SM) of particle physics and General Relativity (GR) by themselves cannot explain astrophysical and cosmological data such as galactic rotation curves, the Cosmic Microwave Background (CMB) and the distribution of structures at large scales.These data indicate the existence of a new fluid, the DM, that is: 1) collisionless 2) cold 3) dominated by GR at large distances.Very few properties are known about the particles making up the DM.The two main ones are: i) the DM must interact weakly with SM particles, and ii) the DM must be stable on cosmological time scales.These two properties by themselves are too general to draw a clear picture of the Dark Sector (DS). In this Thesis we will try to assess some of its properties in light of current and future experiments.The most natural possibility is for the DM to interact with the weakest of the SM forces, the electroweak (EW) force. We completely characterize this kind of DM particles, called WIMPs.After computing their masses, set by EW annihilations, we study their phenomenology at future lepton colliders and at Direct Detection (DD) experiments. The lightest WIMPs are a perfect target for realistic future lepton colliders, while to probe the heaviest ones future Xenon DD experiments are needed.The second scenario we analyze is the case in which DM does not interact with any of the SM force mediators. In this case, the Effective Field Theory (EFT) approach is needed. We introduce a set of portal operators that have received little attention in the past. After describing a model-independent approach, we discuss bounds on the portals coming from high intensity experiments, like neutrino experiments at Fermilab (e.g. DUNE). These are competitive with respect to current constraints.The last possibility is the case in which even portals are absent. In this scenario, the clustering of both species during the Universe evolution can provide a window on the DM nature. We focus on models in which the DM has a long range self-interaction mediated by a light scalar.We study the evolution of inhomogeneities, and compare the predicted CMB anisotropies and galaxy power spectra with current and future data (like Euclid), setting strong bounds on the strength of the self-interaction.Finally we comment on how theoretical insights on DM stability can constrain DM model building
Intelligence and musical mode preference
No full textThe relationship between fluid intelligence and preference for major–minor musical mode was investigated in a sample of 80 university students. Intelligence was assessed by the Raven’s Advanced Progressive Matrices. Musical mode preference was assessed by presenting 14 pairs of musical stimuli that varied only in mode. Mood and personality were assessed, respectively, by the Brief Mood Introspection Scale and the Big Five Questionnaire. Preference for minor stimuli was related positively and significantly to fluid intelligence and openness to experience. The results add evidence of individual differences at the cognitive and personality level related to the enjoyment of sad music
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
Eye and lips in artistic profiles
Full text linkDistortions related to eye and lip morphometry were investigated in two studies comparing photographic versus artistic profiles. In the first study, 298 artistic profiles encompassing the whole art history were compared to 300 photographic profiles. The 2 groups were compared for shape with Procrustes analysis and for size by using 8 indexes. Estimated age was inserted as covariate. The results showed that artists exaggerated eye height and width, pupil width, lip height, and width. The triangular shape of the eye view from side perspective was modified toward a more ellipsoidal shape, depicting the eye from a three-quarter and more frontal perspective. In Study 2, 13 students from the College of the Arts–School of Art were requested to draw a profile portrait of a male or female model. The eye and lip morphometric indexes of the model were compared with those extrapolated from the drawings. The results confirmed an exaggeration of eye width and height, lip width, and pupil width in artistic profiles. Additionally, the eyes shape was “frontalized.” The exaggeration of eye and lip size and the distortion in shape are interpreted and discussed according to the theory linking supernormal stimuli to aesthetic perception
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
