INTEGRAL: status of the mission - after 10 years

The ESA gamma-ray observatory INTEGRAL, launched on 17 October 2002, continues to produce a wealth of discoveries and new results on compact high energy Galactic objects,nuclear gamma-ray line emission, diffuse line and continuum emission, cosmic background radiation, AGN, high energy transients and sky surveys. Ten years after launch, thespacecraft, ground segment and payload are in excellent state-of-health, and INTEGRAL is continuing its scientific operations well beyond its 5-year technical design lifetime until, at least, 31December 2014. This papersummarizes the current status of INTEGRAL.Comment: 6 pages, 2 figures, Proceedings "An INTEGRAL view of the high-energy sky (the first 10 years)", 9th INTEGRAL Workshop and celebration of the 10th anniversary of the launch, Paris, 15-19 October 2012, Proceedings of Science, 201

The role of environmental and technology policies in the transition to a low-carbon energy industry

In a dynamic general equilibrium model we study the interplay between gradual and structural change in the transition to a low-carbon energy industry. We focus on the welfare-theoretic consequences of diverging social and private rates of time preference and a time-to-build feature in capital accumulation. Both features are particularly important in the transformation of energy systems. We show that only a combination of environmental and technology policies can achieve a socially optimal transition. We thus provide a new reason for environmental regulation to be complemented by technology policy such as a non-distortionary investment subsidy.environmental and technology policy, social vs. individual rates of time preference, time to build, gradual vs. structural technological change, energy industry

Gradual versus structural technological change in the transition to a low-emission energy industry: How time-to-build and differing social and individual discount rates influence environmental and technology policies

We develop a general equilibrium model to study the transition from an established polluting to a new clean energy technology. Therefore, we consider two distinctive features: (i) the creation of new productive capital exhibits a timeto-build property, and (ii) the social and individual rates of time preference differ. We derive necessary and sufficient conditions for investment in the new and for replacement of the established technology. We show that, in addition to the standard emission externality, a further market failure stemming from the differing discount rates arises, the extent of which positively depends on the time-lag in capital accumulation. Moreover, we show that in a mutually reinforcing way both market failures create less favorable circumstances for the introduction of the new technology compared to the social optimum. The paper thus provides an additional reason why environmental policy should be complemented by technology policy in the transition to a low-emission energy industry. --energy industry,gradual vs. structural technological change,rate of time preference,time-to-build

Tradable Green Certificates as a Policy Instrument? A Discussion on the Case of Poland

Quota obligation schemes based on tradable green certificates have become a popular policy instrument to expand power generation from renewable energy sources (RES). Their application, however, can neither be justified as a first-best response to a market failure, nor, in a second-best sense, as an instrument mitigating distortionary effects of the emissions externality, if an emissions trading system exists that fully covers the energy industry. We study how ancillary reasons, in form of overcoming various barriers for RES use and establishing beneficial side-effects, such as industry development, energy security, and abatement of pollutants not covered under the ETS, apply to the scheme recently introduced in Poland. While setting substantial expansion incentives, an advantage for local industry or job-market development or energy security can hardly be seen. With rising power prices for end consumers and awareness that the extra rents from the schemes mostly accrue to foreign investors and renewable and polluting generators, we expect a negative impact on social acceptance for RES and RES deployment support policies.tradable green certificates, environmental policy, Poland, Resource /Energy Economics and Policy,

INTEGRAL: science highlights and future prospects

ESA's hard X-ray and soft gamma-ray observatory INTEGRAL is covering the 3 keV to 10 MeV energy band, with excellent sensitivity during long and uninterrupted observations of a large field of view (~100 square degrees), with ms time resolution and keV energy resolution. It links the energy band of pointed soft X-ray missions such as XMM-Newton with that of high-energy gamma-ray space missions such as Fermi and ground based TeV observatories. Key results obtained so far include the first sky map in the light of the 511 keV annihilation emission, the discovery of a new class of high mass X-ray binaries and detection of polarization in cosmic high energy radiation. For the foreseeable future, INTEGRAL will remain the only observatory allowing the study of nucleosynthesis in our Galaxy, including the long overdue next nearby supernova, through high-resolution gamma-ray line spectroscopy. Science results to date and expected for the coming mission years span a wide range of high-energy astrophysics, including studies of the distribution of positrons in the Galaxy; reflection of gamma-rays off clouds in the interstellar medium near the Galactic Centre; studies of black holes and neutron stars particularly in high- mass systems; gamma-ray polarization measurements for X-ray binaries and gamma-ray bursts, and sensitive detection capabilities for obscured active galaxies with more than 1000 expected to be found until 2014. This paper summarizes scientific highlights obtained since INTEGRAL's launch in 2002, and outlines prospects for the INTEGRAL mission.Comment: 39 pages, accepted, 24 October 2011, Space Science Review

Results of the CoreOrganic-Workshop on animal based parameters in Trenthorst, Germany (04.02.08-08.02.2008)

It was the aim of this meeting to train the assessors of several CoreOrganic-Partners (i.e. Austria, Germany, Denmark and Norway) with regard to the methods which are going to be applied in the course of the project on-farm assessments. Training involved animal-based parameters, a resource checklist and a management questionnaire. After a theoretical and practical introduction, inter-observer reliability (IOR) of the main animal-based parameters was tested. This included gait scoring/lameness, body condition, cleanliness and integument alterations. The scoring systems for gait scoring, cleanliness and integument alterations had been adapted from the WelfareQuality® protocol; body condition was scored according to Metzner et al. (1993). Subjective scoring systems which are used in many epidemiological studies have the advantage that they do not require any equipment but - due to the subjectivity of the assessment - it is necessary to achieve acceptable inter-observer reliability (IOR) before and after the study to ensure valid data

Distorted Time Preferences and Time-to-Build in the Transition to a Low-Carbon Energy Industry

We study the welfare-theoretic consequences of diverging social and private time-preference rates and time-to-build for the transition to a low-carbon energy industry. We show that time-to-build, a prevalent characteristic of capital accumulation in the energy sector, amplifies the distortion induced by the split discount rates. Thus, these two characteristics create in a mutually reinforcing way less favorable circumstances for the introduction of new clean energy technologies as compared to the social optimum, even if welfare losses from emissions are internalized. We discuss resulting policy implications with particular emphasis on the energy secto

INTEGRAL and New Classes of High-Mass X-ray Binaries

The gamma-ray observatory INTEGRAL, launched in October 2002, produces a wealth of discoveries and new results on compact high energy Galactic objects, nuclear gamma-ray line emission, diffuse line and continuum emission, cosmic background radiation, AGN and high energy transients. Two important serendipitous discoveries made by the INTEGRAL mission are new classes of X-ray binaries, namely the highly-obscured high-mass X-ray binaries, and the super-giant fast transients. In this paper I will review the current status of these discoveries.Comment: 3 pages, 1 figure, submitted; Proceedings "The nature and evolution of X-ray binaries in diverse environments", St Petersburg/FL, USA, 28 Oct - 02 Nov 200
