The many lives of magnetized neutron stars

The magnetic field strength at birth is arguably one of the most important properties to determine the evolutionary path of a neutron star. Objects with very high fields, collectively known as magnetars, are characterized by high X-ray quiescent luminosities, occurrence of outbursts, and, for some of them, sporadic giant flares. While the magnetic field strength is believed to drive their collective behaviour, however, the diversity of their properties, and, especially, the observation of magnetar-like bursts from “low-field” pulsars, has been a theoretical puzzle. In this review, we discuss results of long-term simulations following the coupled evolution of the X-ray luminosity and the timing properties for a large, homogeneous sample of X-ray emitting isolated neutron stars, accounting for a range of initial magnetic field strengths, envelope compositions, and neutron star masses. In addition, by following the evolution of magnetic stresses within the neutron star crust, we can also relate the observed magnetar phenomenology to the physical properties of neutron stars, and in particular to their age and magnetic field strength and topology. The dichotomy of “high-B” field pulsars versus magnetars is naturally explained, and occasional outbursts from old, low B-field neutron stars are predicted. We conclude by speculating on the fate of old magnetars, and by presenting observational diagnostics of the neutron star crustal field topology.

Extending Working Lives: The Case of Denmark. CEPS Working Document No. 404, 17 February 2015

Extending working lives has been a key item on the political agenda in Denmark for at least two decades now. This study details recent and prospective reforms to the voluntary early retirement scheme and the pension age, as well as current policy initiatives to keep older workers in employment. Other aspects central to a long working life, such as health, lifelong learning, age management practices in companies, and elderly workers’ motivation are discussed in depth. Overall, Denmark is in a relatively good state when it comes to older workers’ labour market participation and related job satisfaction. This impacts positively on the public finance challenge linked to population ageing which, given agreed reforms, should be manageable. Ongoing reform implementation is likely to substantially increase the employment of those aged 60 and over. Nevertheless, surveys point to age discrimination as a potential problem and people who fall into unemployment at a late stage of their careers still face challenges to reemployment.

Extending Working Lives: A comparative analysis of how governments influence lifelong learning, CEPS Special Report No. 111, July 2015

This report offers a comparative policy study on adult learning within the scope of complementary research conducted by Beblavý et al. (2013) on how people upgrade their skills during their adult lifetimes. To achieve our objectives, we identified regulatory policies and financial support in 11 countries for two main categories of learning: formal higher education and employer-based training. Drawing upon the results of the country reports carried out by our partners in the MoPAct project, we found that in none of the countries examined is there an ‘older student’ policy. In most cases grants and financial support are awarded only up until a certain age. In all of the countries studied, standard undergraduate and post-graduate studies are available for part-time students. The distribution of full-time students and part-time students in tertiary education varies from one country to another as well as from one age group to another. The participation in full-time tertiary education programmes decreases with the age of students. In Lithuania, Latvia, Poland and the UK, there are no mandatory policies to ensure employer-based training. However, in Belgium, Czech Republic, Denmark, Estonia, Germany, Italy, the Netherlands and Spain, employer-based training is more clearly regulated and the employers might have obligations to provide training for their staff. Taking into consideration Beblavý et al. (2013), we observe that comparative differences across countries can be related to policy differences only in some cases. The policy framework seems to impact more the employer-based training than the educational attainment (upgrade of ISCED level). In Denmark, the Netherlands, Latvia, Lithuania, Czech Republic and Poland, we find a perfect match between policy outcomes and the results of Beblavý et al. (2013) related to employer-based training. This is not the case in the United Kingdom, where the two aspects observed are not correlated.

Measuring ageing and the need for longer working lives in the EU. CEPS Working Document No. 417/February 2016 Wednesday, 24 February 2016

This study considers different ways of measuring the ageing of societies and their implications for public policy. The first part characterises the ongoing ageing of the population in the EU28 by relating it to past and future longer-term demographic trends for broad groups of countries. It goes beyond traditional chronological measures to include recently suggested prospective measures of ageing. The second part of the study is concerned with economic dependency ratios; a more relevant measure for summarising the economic challenges related to ageing. Three main findings emerge: first, prospective indicators of ageing reveal the challenge of population ageing to be less onerous than traditional chronological measures would suggest. Their relevance, however, will depend on the degree to which policy changes can respond to the changing age structure of the population. Second, substantial increases in the length of working lives are necessary to maintain current economic dependency ratios. Taking a year-2000 perspective view of the economic challenges of ageing shows that substantial progress has been made. Third, looking towards 2050, education will have limited direct impact on the scale of the ageing challenge.
