Whistleblowing is a powerful and rather inexpensive instrument to deter tax evasion. Despite the deterrent effects on tax evasion, whistleblowing can reduce trust and undermine agents’ attitude to cooperate with group members. Yet, no study has investigated the potential spillover effects of whistleblowing on ingroup cooperation. This paper reports results of a laboratory experiment in which subjects participate in two consecutive phases in unchanging groups: a tax evasion game, followed by a generalized gift exchange game. Two dimensions are manipulated in our experiment: the inclusion of a whistleblowing stage in which, after observing others’ declared incomes, subjects can signal other group members to the tax authority, and the provision of information about the content of the second phase before the tax evasion game is played. Our results show that whistleblowing is effective in both curbing tax evasion and improving the precision of tax auditing. Moreover, we detect no statistically significant spillover effects of whistleblowing on ingroup cooperation in the subsequent generalized gift exchange game, with this result being unaffected by the provision of information about the experimental task in the second phase. Finally, the provision of information does not significantly alter subjects’ (tax and whistleblowing) choices in the tax evasion game: thus, knowledge about perspective ingroup cooperation did not alter attitude toward whistleblowing.

What is the relationship between thinking and seeing a form? In his morphological writings Goethe answers this question by saying that seeing is not pure passivity, but a thoughtful look because it invokes the mobility and plasticity of our thinking. For this reason this kind of aesthetic gaze is useful to understand the world of life, equally mobile and plastic. In this article, I will try to find out whether Goethe’s considerations about aesthetic idea and plasticity can find a new-look in the reflections of Catherine Malabou, one of the most influential thinkers in contemporary French debate, in whose works the concept of plastic form is central.

This article wants to investigate the logic of mimicry and their communicative function in animal life adopting an aesthetical perspective. The relationship between appearance and not-appearance, between the act of making itself visible and the act of disguising itself, is investigated starting from the morphological thought of the Swiss biologist Adolf Portmann, in a continuous dialogue with great thinkers of past and actual time – Johann Wolfgang Goethe, Hannah Arendt and Roger Caillois – and with the artistic illustrations of the American painter Abbott Thayer, concerned with the laws of color camouflage. This productive relationship among biology, aesthetics and artistic practice allows us to show that the sphere of the skin, far from being "superficial" and meaningless, is the privileged point of view for a true semiotics of the visible.

The concept of cell, more than any other biological concept, has been modelled on three powerful metaphors: in a morphological perspective, the cell has been defined Baustein, the brick or elementary unit of the body; from the physiological point of view, it has been associated to a chemical laboratory and finally, in a systemic view, it has been compared to the citizen of the cellular state. The pathologist Rudolf Virchow and the zoologist Ernst Haeckel showed the philosophical and aesthetic potential of the latter metaphor, opening two different perspectives on a crucial problem in the science of living: the problem of the definition of biological individual.

Nell'apprendimento dell'italiano come lingua straniera da parte di ispanofoni l'affinità tra L1 ed L2 emerge come un'arma a doppio taglio: nella fase iniziale facilita l'apprendimento e la comunicazione in LS, ma, una volta raggiunto un livello intermedio nella LS, tale parentela causa un gran numero di fenomeni di transfer dalla L1 con errori che rischiano di fossilizzarsi nel tempo e che richiedono pertanto un'attenzione particolare per essere corretti. In questo lavoro di ricerca, svolto presso il Liceo Scientifico E. Fermi della Scuola Statale Italiana di Madrid, sono stati rilevati i fenomeni di transfer negativo presenti nelle produzioni scritte e orali degli studenti madrelingua spagnoli. Le occorrenze piú frequenti sono state raggruppate in tre ambiti principali: fonologico, morfologico e lessicale. For Spanish speakers learning Italian as a foreign language, the affinity between L1 and L2 is a double-edged sword: in the initial phase, it facilitates learning and communication in the FL, but once it they have reached an intermediate level in the foreign language, the similarity causes a lot of transfer from the L1 with errors that risk becoming fossilized over time and require particular attention so that they are corrected. In this study, carried out at the Liceo Scientifico E. Fermi at the Scuola Statale Italiana in Madrid, negative transfer phenomena in the oral and written production of mother tongue Spanish speakers were found. The most frequent occurences were grouped into three main areas: phonological, morphological and lexical
