- The Simons Observatory (SO) is a new cosmic microwave background experiment being built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the scientific goals of the experiment, motivate the design, and forecast its performance. SO will measure the temperature and polarization anisotropy of the cosmic microwave background in six frequency bands centered at: 27, 39, 93, 145, 225 and 280 GHz. The initial con figuration of SO will have three small-aperture 0.5-m telescopes and one large-aperture 6-m telescope, with a total of 60,000 cryogenic bolometers. Our key science goals are to characterize the primordial perturbations, measure the number of relativistic species and the mass of neutrinos, test for deviations from a cosmological constant, improve our understanding of galaxy evolution, and constrain the duration of reionization. The small aperture telescopes will target the largest angular scales observable from Chile, mapping approximate to 10% of the sky to a white noise level of 2 mu K-arcmin in combined 93 and 145 GHz bands, to measure the primordial tensor-to-scalar ratio, r, at a target level of sigma(r) = 0.003. The large aperture telescope will map approximate to 40% of the sky at arcminute angular resolution to an expected white noise level of 6 mu K-arcmin in combined 93 and 145 GHz bands, overlapping with the majority of the Large Synoptic Survey Telescope sky region and partially with the Dark Energy Spectroscopic Instrument. With up to an order of magnitude lower polarization noise than maps from the Planck satellite, the high-resolution sky maps will constrain cosmological parameters derived from the damping tail, gravitational lensing of the microwave background, the primordial bispectrum, and the thermal and kinematic Sunyaev-Zel'dovich effects, and will aid in delensing the large-angle polarization signal to measure the tensor-to-scalar ratio. The survey will also provide a legacy catalog of 16,000 galaxy clusters and more than 20,000 extragalactic sources.

- Using original survey data, we investigate how British, French and Swedish managers scanned their political environments during the crisis in the Eurozone. We expose instances when country of origin has a significant effect on scanning practices: British managers claimed to possess the most developed political scanning capabilities, making the most frequent use of government information sources. British and Swedish managers used business associations as intelligence sources more frequently than their French counterparts. We also found that exposure to the Euro crisis significantly affected scanning behaviours: irrespective of country of origin, managers strongly exposed to the crisis considered it strategically important to scan political events during the crisis, developed formal scanning routines, and reported frequent use of both governments and business associations as sources of political information. Combined, our findings contribute to county-specific research into executives’ environmental scanning practices by suggesting a universal mind-set of environmental scanning during times of crisis.

The Role of Political Intelligence in Firms' Export Decisions During the Euro Crisis
- 2016

- Inspired by the literatures on internationalization and absorptive capacity, we develop a model exploring how small firms—during crises—acquire and apply political information to export decisions. We test our model using data collected during the 2012 Eurozone crisis from a sample of 440 British, French, and Swedish SMEs. Findings indicate that firms dependent on the Eurozone for exports and heavily impacted by the crisis engaged in frequent political monitoring. In turn, frequent monitoring leads to the development of formal routines for exploiting political information. Firms with the most formal routines sought new export opportunities beyond the Eurozone. In contrast to previous research into small-firm internationalization, our study stresses the significance of "shortcut" searching activities, non-market information, and firms' decisions to reduce prior investments in export markets.
