- Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint objects, a flexibly-pointed instrument capable of high astrometric accuracy is an ideal complement to current astrometric surveys and a unique tool for precision astrophysics. Such a space-based mission will push the frontier of precision astrometry from evidence of Earth-mass habitable worlds around the nearest stars, to distant Milky Way objects, and out to the Local Group of galaxies. As we enter the era of the James Webb Space Telescope and the new ground-based, adaptive-optics-enabled giant telescopes, by obtaining these high precision measurements on key objects that Gaia could not reach, a mission that focuses on high precision astrometry science can consolidate our theoretical understanding of the local Universe, enable extrapolation of physical processes to remote redshifts, and derive a much more consistent picture of cosmological evolution and the likely fate of our cosmos. Already several missions have been proposed to address the science case of faint objects in motion using high precision astrometry missions: NEAT proposed for the ESA M3 opportunity, micro-NEAT for the S1 opportunity, and Theia for the M4 and M5 opportunities. Additional new mission configurations adapted with technological innovations could be envisioned to pursue accurate measurements of these extremely small motions. The goal of this White Paper is to address the fundamental science questions that are at stake when we focus on the motions of faint sky objects and to briefly review instrumentation and mission profiles.

The syndication of venture capital investments in Europe: evidence from five European countries
- 2002

- Financial theory, resource-based theory and deal flow generation are used to explain synd ication practices among venture capitalists in Belgium, France, The Netherlands, Sweden and the UK. Similar motives drive syndication in the five countries: the desire to share risk and increase portfolio diversification is more important than the desire to access additional intangible resources or deal flow. When resource-based motives are more important, however, the propensity to syndicate increases. Syndication practices are more important in young venture capital (VC) firms and in VC firms with more portfolio companies.

Synthesizing plausible futures for biodiversity and ecosystem services in Europe and Central Asia using scenario archetypes
- 2019

Ingår i: Ecology and Society. - 1708-3087. ; 24:2

Tidskriftsartikel (refereegranskat)abstract
- Scenarios are a useful tool to explore possible futures of social-ecological systems. The number of scenarios has increased dramatically over recent decades, with a large diversity in temporal and spatial scales, purposes, themes, development methods, and content. Scenario archetypes generically describe future developments and can be useful in meaningfully classifying scenarios, structuring and summarizing the overwhelming amount of information, and enabling scientific outputs to more effectively interface with decision-making frameworks. The Intergovernmental Platform for Biodiversity and Ecosystem Services (IPBES) faced this challenge and used scenario archetypes in its assessment of future interactions between nature and society. We describe the use of scenario archetypes in the IPBES Regional Assessment of Europe and Central Asia. Six scenario archetypes for the region are described in terms of their driver assumptions and impacts on nature (including biodiversity) and its contributions to people (including ecosystem services): business-as-usual, economic optimism, regional competition, regional sustainability, global sustainable development, and inequality. The analysis shows that trade-offs between nature's contributions to people are projected under different scenario archetypes. However, the means of resolving these trade-offs depend on differing political and societal value judgements within each scenario archetype. Scenarios that include proactive decision making on environmental issues, environmental management approaches that support multifunctionality, and mainstreaming environmental issues across sectors, are generally more successful in mitigating tradeoffs than isolated environmental policies. Furthermore, those scenario archetypes that focus on achieving a balanced supply of nature's contributions to people and that incorporate a diversity of values are estimated to achieve more policy goals and targets, such as the UN Sustainable Development Goals and the Convention on Biological Diversity Aichi targets. The scenario archetypes approach is shown to be helpful in supporting science-policy dialogue for proactive decision making that anticipates change, mitigates undesirable trade-offs, and fosters societal transformation in pursuit of sustainable development.

Boundary objects in network interactions
- 2018

Ingår i: Industrial Marketing Management. - : Elsevier. - 0019-8501 .- 1873-2062. ; 74, s. 187-194

- The purpose of this paper is to investigate the mediating role of boundary objects in interaction processes within business networks. From a single case study in the grocery retail industry, we find that such objects are used within interaction processes for collaboration, but are also used extensively for handling conflict, facilitating economic negotiations, and power execution. As such, network-level boundary objects do not require broad consensus by all the involved actors, but instead narrow consensus in a particular interaction process.

A process for identifying national solutions to challenges faced in developing countries in reporting to environmental conventions : Insight from the facilitating national reporting to the rio conventions project
- 2015

Tidskriftsartikel (refereegranskat)abstract
- Almost all countries in the world are party to the Rio Conventions. This entails a number of responsibilities, including reporting periodically on aspects of environmental health and national implementation of the convention. These reports can cover hundreds of pages, so completing reports is often a significant undertaking. Since countries can be party to numerous Multilateral Environmental Agreements (MEAs), they may have several such reports to prepare at any one time, often using similar information. This article shares insights from a project that piloted nationally-driven, integrated approaches to reporting to the Rio Conventions and developed flexible methods for enhancing the national reporting process, in a way that is relevant for a particular country. The project found that a focus on collaborative institutional arrangements and building capacity as a nation, rather than as a series of departments, could enhance this reporting process. These lessons can inform decisions of United Nations agencies, MEA secretariats, Country Parties to these MEAs and the wider sustainability community to reduce the reporting burden and increase the synergistic implementation of environmental conventions.
