Re-introduction of the Mallorcan midwife toad, Mallorca, Spain

The Mallorcan midwife toad (Alytes muletensis, Sanchíz & Alcover, 1977) or ferreret was first described in the 1970s as Baleaphryne muletensis from upper Pleistocene fossils, and was considered extinct. The discovery of live tadpoles in 1980 led to further research which confirmed the species as extant and endemic to Mallorca (Mayol & Alcover, 1981). Subfossils suggest that the species was once widespread across the island, but today it is confined to a few gorges within the Serra de Tramuntana mountains in the north-west part of the island. There are currently about 34 populations within the mountains and adjacent areas (16 original wild populations plus 18 re-introductions). These are largely isolated from each other by physiographic barriers, but there is little evidence of any inbreeding depression. Re-introduction of captive bred toads started in 1989 and it is estimated that about 25% of the wild toads stem from captive bred stock. The successful re-introduction program contributed to the downgrading of the species from ‘Critically Endangered’ to ‘Vulnerable’ in the Global Amphibian Assessment of 2004. There is little evidence that wild populations are continuing to decline, but the recent discovery of chytridiomycosis in four populations gives cause for concern

Internet gambling: an overview of psychosocial impacts

Technological innovation has always played a role in the development of gambling behaviour, primarily through providing new market opportunities. Early prevalence studies of Intemet gambling in the UK, Canada and the US have shown that Intemet gambling is not a eause for concern at present. However, this seems likely to change as more people start to use the Internet for leisure activities. After a brief overview of gambling technologies and deregulation issues, this paper examines the impact of technology on gambling by highlighting salient factors in the rise of Intemet gambling (i.e., accessibility, affordability, anonymity, convenience, escape immersion/dissociation, disinhibition, event frequency, asociability, interactivity, and simulation). The paper also overviews some of the main social impacts surrounding Intemet gambling, such as protection of the vulnerable, Intemet gambling in the workplace, electronic cash, and unscrupulous operators. Recommendations for Internet gambling operators are also provided

Black Hole Mass of the Ultraluminous X-ray source M82 X-1

We report the first clear evidence for the simultaneous presence of a low frequency break and a QPO in the fluctuation power spectrum of a well known ultraluminous X-ray source (ULX) in M82 using long XMM-Newton observations. The break occurs at a frequency of 34.2_{-3}^{+6}mHz. The QPO has a centroid at 114.3\pm1.5mHz, a coherence Q~3.5 and an amplitude (rms) of 19% in the 2-10keV band. The power spectrum is approximately flat below the break frequency and then falls off above the break frequency as a power law with the QPO superimposed. This form of the power spectrum is characteristic of the Galactic X-ray binaries (XRBs) in their high or intermediate states. M82 X-1 was likely in an intermediate state during the observation. The EPIC PN spectrum is well described by a model comprising an absorbed power-law (Gamma~2) and an iron line at ~6.6keV with a width sigma~0.2keV and an equivalent width of ~180eV. Using the well established correlations between the power and energy spectral parameters for XRBs, we estimate a black hole mass for M82 X-1 in the range of 25-520Msun including systematic errors that arise due to the uncertainty in the calibration of the photon spectral index versus QPO frequency relation.Comment: Final version, accepted for publication in ApJ Letter

THE LESSONS FROM THE EURO EXPERIENCE

Esse artigo examina a experiência da união econômica e monetária europeia sobre três perspectivas - o design, a implementação e a gestão do euro – antes de explorar as implicações da crise atual.Twenty years ago, amid a great fanfare of enthusiasm, the Treaty of Maastricht created the European union and inaugurated the process for creating a single European currency for most of the then members (except the UK and Sweden, and later Denmark, that were given a temporary exemption) and all future members. Twenty years later, the anniversary of the treaty passed almost unnoticed (European Policy Centre, 2012). On that day, however, the impact of the treaty was never far from the headlines, as had also been the case for almost every day over the previous months. The Lehman brothers bankruptcy in September 2008 not only triggered a financial crisis that threatened to engulf the world, but it set in motion a series of shocks that have since reverberated through the Euro-area. It is fair to say that the crisis-management has not been an example of stream-lined efficiency, and there are lessons to be learned from that experience.However, the development of the Euro, and the crisis that has subsequently engulfed it, holds lessons in another direction. The European Union has long been held as a model, or an inspiration, for other experiments in regional cooperation and integration, including Mercosul, ASEAN and SADC. The model embodied an sequence of steps leading to ‘ever closer union’ that moved from a free trade area through a customs union and a single market and culminated in economic and monetary union. With the signing and implementation of the Treaty of Maastricht, the European Union had embarked on the penultimate step in this progression. But only half of it – a monetary union without a fiscal union. The Euro-crisis has now called that achievement into question and, in the process, undermined the authority of those espousing a European route towards closer integration, both for themselves as well as for other nations. As a convinced federalist, myself, I would not recommend abandoning the European example altogether, but if there is a lesson to be learned from this sorry episode, it is this: “if you are going to do it, do not do it this way”.This article examines the European experience with economic and monetary union from three perspectives – the design, the implementation and the management of the euro – before exploring the implications of the current crisis
