Catch Me If You Can: Testing the reduction of compound lotteries axiom in a tax compliance experiment
Full text linkWe test the Reduction of Compound Lotteries Axiom (RCLA) in an experiment on tax compliance. We disentangle the compound probability of audit and detection and test it against a more realistic situation with a probability of audit and a subsequent probability of detection. Various experiments have shown that abstract framing often leads to violations of the RCLA; our framed set-up also reveals statistically significant departures from the RCLA. We find that subjects comply more in the two-stage lottery set-up than they do in the one-stage equivalent and that violations are compatible with subjects applying different weighting functions to one-stage lotteries versus two-stage lotteries: inverse S-shaped - likelihood insensitive - in the former set-up; and significantly less insensitive in the latter. Violations substantially decline with subjects’ experience but not at the same rate for all groups of subjects
I terrazzi marini dell'isola di Salina (Isole Eolie, Tirreno meridionale): un ipotesi di datazione
No full textHolocenic shorelines and tectonic uplift of the island of Lipari (Aeolian Arc, Southern Italy)
No full textWe discuss 2 succeeding phases in the evolution of Lipari island. At first, 8 orders of marine terraces were recognized on the ground of geomorphological, sedimentological and paleontological evidences. The U 234/U 238 dataings of the fossil shells recovered from terraces III and V have allowed to set the age of these ancient shorelines. These datings implemented with those from the literature, make the basis for the construction of an uplift/sinking diagram. From this latter it seems that a sinking has occurred approximately during the Eutyrrhenian. The subsequent rise took place at a rate of 0.73-0.33cm/yr
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
Ab initio infrared spectrum of liquid water.
No full textAn ab initio calculation of the infrared spectrum of liquid water has been performed using Car-Parrinello molecular dynamics and evaluating the electronic polarization by means of the Berry phase formulation. The major features of the spectrum are in good agreement with experiments and are shown to arise from specific vibrational motions of the water molecules. The effect of quantum corrections to the spectrum is discussed
Ab initio infrared absorption study of the hydrogen-bond symmetrization in ice.
No full textWe computed from first principles the infrared spectrum of ice at high pressure in the molecular phases VIII and VII and in the symmetric phase X by performing Car-Parrinello molecular dynamics simulations and evaluating the electronic polarization by means of the Berry phase formulation. The theoretical spectra are in good agreement with the experimental data and let us establish an unambiguous correspondence between the infrared spectrum and the underlying structure of the three different phases of ice
