Data Driven Discovery in Astrophysics
We review some aspects of the current state of data-intensive astronomy, its
methods, and some outstanding data analysis challenges. Astronomy is at the
forefront of "big data" science, with exponentially growing data volumes and
data rates, and an ever-increasing complexity, now entering the Petascale
regime. Telescopes and observatories from both ground and space, covering a
full range of wavelengths, feed the data via processing pipelines into
dedicated archives, where they can be accessed for scientific analysis. Most of
the large archives are connected through the Virtual Observatory framework,
that provides interoperability standards and services, and effectively
constitutes a global data grid of astronomy. Making discoveries in this
overabundance of data requires applications of novel, machine learning tools.
We describe some of the recent examples of such applications.Comment: Keynote talk in the proceedings of ESA-ESRIN Conference: Big Data

Rethinking Research Partnerships: Discussion Guide and Toolkit
In recent years, there has been a drive towards research collaboration between academics and international non-governmental organisations (INGOs). These new partnerships offer exciting opportunities to improve learning and practice in international development, leading to innovation and deepened understandings of the world and, ultimately, a better impact on poverty eradication. However, they also present considerable challenges. How do organisations with different structures, goals and interests collaborate? Can they work together productively around these differences? What tensions exist and what is the impact of these? How is power distributed and which voices are amplified or lost in the process?
This guide does not seek to answer these questions, but offers a way of exploring them. It is aimed at people and organisations that are considering embarking on a research collaboration, or are already working in partnership. It introduces some of the key issues that arise when working collaboratively, and suggests tools and activities to help you to critically reflect on them. The guide is aimed at those at the forefront of these partnerships â academics, INGO staff and their respective institutions. However, the content will also be of relevance to funders and others seeking to support or encourage collaborative
research approaches.
This guide is a toolkit for critical reflection, rooted in the idea that research partnerships must be entered into with care. Attention needs to be given to contexts, power relations and the different interests involved in order to successfully deliver truly collaborative knowledge generation that serves everyoneâs interests. The risks are real â partnerships without serious considerations of the power dynamics risk reaffirming certain interests and voices and marginalising others, particularly those already experiencing structural disadvantage, undermining the real benefit that these partnerships can bring. In addition, they can end up placing unfunded and unsupported burdens on particular individuals or organisations, and reinforce existing structures that constrain the intended learning and growth

Which conceptual foundations for environmental policies? An institutional and evolutionary framework of economic change
This paper draws on institutional and evolutionary economics and contributes to an approach to environmental policy which diverges from mainstream prescriptions. The 'socio-technical system' is the core concept: this is a complex made of co-evolving institutions, technologies, markets and actors that fulfils an overall societal need (such as housing, production, mobility, etc.). A systemic and dynamic analysis of those structural changes which are needed to create more sustainable socio-technical systems is provided; actors â and their ability to influence politics and policy â are explicitly taken into consideration. Unsustainable socio-technical systems feature a relevant resistance to change, because they are embedded in the very structure of our society and because of the conservative action of dominant stakeholders; this is why no environmental policy will be effective unless it aims at 'unlocking' our societies from their dominance. But also a constructive side of environmental policy is needed in order to establish new and more sustainable socio-technical systems; consistently, environmental policy is viewed as a combination of actions that can trigger, make viable and align those institutional, technological and economic changes which are needed to reach sustainability. Again, actors (for change) are at the heart of this vision of environmental policy: as subject, because the creation of new and sustainable socio-technical systems is made possible by (coalitions of) actors for change; as object, because environmental policy â to be effective â must actively support the empowerment, legitimation and social networking of such coalitions. A âchicken and eggâ problem remains: who comes first? Actors for change advocating policies for sustainability or policies for sustainability supporting actors for change?Environmental policy; Economic dynamics; Institutional economics; Evolutionary economics; Socio-technical systems
