Las aspiraciones creativas de un copista: la intervención de Diego Martínez de Mora en 'Un castigo en tres venganzas'

En el presente trabajo se estudia el manuscrito de la comedia 'Un castigo en tres venganzas', debido a Diego Martínez de Mora. Copista, librero, memorión y posiblemente actor, los textos conservados que fueron transcritos por él proyectan el perfil de un personaje singular difícilmente encasillable en el entramado que modela el complejo proceso de transmisión de nuestro teatro áureo. Analizaré los tres estadios en los que se puede organizar su grado de intervención con respecto al texto calderoniano, desde la mera enmienda puntual hasta la libre manifestación de sus pretensiones más puramente creativas reflejada en la inclusión de series de versos inéditos en el resto de testimonios e incluso de una escena completa. In this paper I study the manuscript of the play entitled 'Un castigo en tres venganzas', by Diego Martínez de Mora. Copyist, bookseller, 'memorión' and maybe even an actor, the existing texts transcribed by him show the profile of a remarkable person that is hard to be pigeonholed in the network that shape the complex transmission process of our Golden Age theater. I’ll analyze the three different stages in which his intervention in Calderon’s text can be organized from the simple precise correction to the moment when he gave free rein to his creative desires as it can be proved in the number of verses (even a whole new scene) that he decided to include and are totally unknown in the rest of the printed versions of the text

The black beat of Lisbon: Sociabilities, music and resistances

Since the 1970s, Portugal has established itself as one of the largest migratory flows of Africans to Europe, especially from its former colonies to the Portuguese capital. Gradually, there are numerous precarious and informal construction neighborhoods, with the presence of Angolans, Cape Verdeans, Guineans and Sao Tome, where cultural expressions of the diaspora's musical repertoire are affirmed. From the 2000s, the phenomenon of music digitization contributed to the maintenance of permanent and instantaneous exchanges with what was played and consumed in the countries of origin. New opportunities for crosses and reinterpretations of musical genres have become possible, reinforced by the local senses conferred by young people born and / or raised in Afro-Lisbon producing innovative aesthetic expressions. Started by young blacks, a musical scene with its own circuits of production, circulation and consumption known as "batida" appears in the outskirts of Lisbon, a style influenced by African rhythms, namely Angola's kuduro and electronic music. Djs were the main responsible for affirming this new style, giving this sound a centrality in the market of youth consumption in Portugal and in Europe. Quinta do Mocho is a key neighborhood to understand this dynamics, where from very precarious conditions, some young people took advantage of the opportunities offered by digital devices to create this rhythm, also moving local sociabilities and parties. Home to some of the country's top "batida" Djs, Quinta do Mocho has become an area of intense musical production, where home studios and street parties influence the new global fashions. If some of the DJs in the neighborhood make a music career, most of them do not have the opportunity to make it a full and autonomous profession. In this article, we propose to analyze the trajectories of these young Djs, correlating their life experiences with the transformations that have occurred in the neighborhood and in the musical genre "beat" in recent years. We intend to analyze the relationship between creativity and sociability in music with the resistances built by them in relation to racism, segregation and colonialist forms of social demarcation of existence, space and knowledge.info:eu-repo/semantics/acceptedVersio

Ultralight boson cloud depletion in binary systems

Ultralight scalars can extract rotational energy from astrophysical black holes through superradiant instabilities, forming macroscopic boson clouds. This process is most efficient when the Compton wavelength of the boson is comparable to the size of the black hole horizon, i.e. when the "gravitational fine structure constant" $\alpha\equiv G \mu M/\hbar c\sim 1$. If the black hole/cloud system is in a binary, tidal perturbations from the companion can produce resonant transitions between the energy levels of the cloud, depleting it by an amount that depends on the nature of the transition and on the parameters of the binary. Previous cloud depletion estimates considered binaries in circular orbit and made the approximation $\alpha\ll 1$. Here we use black hole perturbation theory to compute instability rates and decay widths for generic values of $\alpha$, and we show that this leads to much larger cloud depletion estimates when $\alpha \gtrsim 0.1$. We also study eccentric binary orbits. We show that in this case resonances can occur at all harmonics of the orbital frequency, significantly extending the range of frequencies where cloud depletion may be observable with gravitational wave interferometers.Comment: 12 pages, 6 figures. v2: references added, matches published versio

Signalling with dividends? new evidence from Europe

According to the dividend signalling hypothesis, dividend change announcements trigger share returns because they convey information about management’s assessment on firms’ future prospects. We analyse the classical assumptions of the dividend signalling hypothesis, using data from three European countries. The evidence gives no support to a positive relation between dividend change announcements and the market reaction for French firms, and only weak support for the Portuguese and UK firms. After accounting for non-linearity in the mean reversion process, the global results do not give support to the assumption that dividend change announcements are positively related with future earnings changes. We also formulate two hypotheses in order to explore the window dressing phenomenon and the maturity hypothesis, finding some evidence in favour of both, especially in the UK market

Lower propensity to pay dividends? new evidence from Europe

Recently, some empirical studies reported the phenomenon of the low propensity of firms to dividend payment, concluding that companies have become less likely to pay dividends. In addition, the major parts of these studies sustain the investors’ expectations regarding dividend payments also decreased. We analyse the propensity to pay dividends in three European markets: Portugal, France and the UK. Although they are all European markets, they are different from each other for several reasons. Firstly, the UK is one of the most important European capital markets, whereas the French and Portuguese markets are smaller, specially Portugal, that is a very small market compared to other Western European markets. Additionally, these two markets are less intensively researched. Secondly, we have differences in these countries associated with the ownership of equity. In Portugal and France ownership tends to be more concentrated than in the UK. Thirdly, Portugal and France are bank-based system, whereas the UK is a market-based system. Finally, the legal rules covering protection of corporate shareholders is different in the three countries. While the UK is a country of Anglo-Saxon influence, the other two countries are characterised by a continental influence. We find evidence of the decline of firms paying dividends, except for the French market. Moreover, we find evidence suggesting that the Portuguese market does not have such a smoothing dividend policy like the US or the UK markets, but it has a more volatile dividend policy, such as the case of the German market

The phenomenon of the adverse market reaction to dividend change announcements: new Eeidence from Europe

The dividend policy is one of the most debated topics in the finance literature. According to the dividend signalling hypothesis, which has motivated a significant amount of theoretical and empirical research, dividend change announcements trigger share returns because they convey information about management’s assessment on firms’ future prospects. Consequently, a dividend increase (decrease) should be followed by an improvement (reduction) in a firm’s value. Although there are empirical evidence supporting the positive relationship between dividend change announcements and the subsequent share price reactions, some studies have not supported this idea. Furthermore, several studies found evidence of a significant percentage of cases where share prices reactions are opposite to the dividend changes direction, like the works of Asquith and Mullins (1983), Benesh, Keown and Pinkerton (1984), Born, Mozer and Officer (1988), Dhillon and Johnson (1994) Healy, Hathorn and Kirch (1997), and, more recently, Vieira (2005). We introduce a new approach to investigate the relationship between the market reaction to dividend changes and future earnings changes with the purpose of understanding why the market sometimes reacts negatively (positively) to dividend increases (decreases). We find only weak evidence for the dividend information content hypothesis. The Portuguese results suggest that the adverse market reaction to dividendchange announcements is basically due to the fact that the market does not understand the signal given by firms though dividend change announcements. Moreover, we find no evidence of the inverse signalling effect, except for the UK market. The results suggest that the UK market investors have more capability to predict future earnings than the investors of the Portuguese and the French markets

The effect of firm-specific factors on the market reaction to dividend change announcements: new evidence from Europe

The dividend policy is one of the most debated topics in the finance literature. According to the dividend signalling hypothesis, which has motivated a significant amount of theoretical and empirical research, dividend change announcements trigger share returns because they convey information about management’s assessment on firms’ future prospects. Consequently, a dividend increase (decrease) should be followed by an improvement (reduction) in a firm’s value. However, some studies have not supported the hypothesis of a positive relationship between dividend change announcements, and the subsequent share price reaction, such as the ones of Lang and Litzenberger (1989), Benartzi, Michaely and Thaler (1997), Chen, Firth and Gao (2002), Abeyratna and Power (2002) and Vieira (2005). Furthermore, some authors found evidence of a significant percentage of cases where share prices reactions are opposite to the dividend changes direction, like the works of Asquith and Mullins (1983), Benesh, Keown and Pinkerton (1984), Born, Mozer and Officer (1988), Dhillon and Johnson (1994) Healy, Hathorn and Kirch (1997), and, more recently, Vieira (2005). Consequently, we try to identify firm-specific factors that contribute in explaining the adverse market reaction to dividend change announcements. Globally, our evidence suggests that only for the UK sample we have firm-specific factors influencing the market reaction to dividend change announcements. We conclude that the UK firms with a negative market reaction to dividend increase announcements have, on average, higher size, lower earnings growth rate and lower debt to equity ratios

Best approach regions for potential spaces

We characterize the approach regions so that the non-tangential maximal function is of weak-type on potential spaces, for which we use a simple argument involving Carleson measure estimates
