GW170817: Observation of Gravitational Waves from a Binary Neutron Star Inspiral

2017

On August 17, 2017 at 12-41:04 UTC the Advanced LIGO and Advanced Virgo gravitational-wave detectors made their first observation of a binary neutron star inspiral. The signal, GW170817, was detected with a combined signal-to-noise ratio of 32.4 and a false-alarm-rate estimate of less than one per 8.0×104 years. We infer the component masses of the binary to be between 0.86 and 2.26 M, in agreement with masses of known neutron stars. Restricting the component spins to the range inferred in binary neutron stars, we find the component masses to be in the range 1.17-1.60 M, with the total mass of the system 2.74-0.01+0.04M. The source was localized within a sky region of 28 deg2 (90% probabili…

Negotiation strategies and offers : perceptions of mergers and acquisitions advisors

2014

This thesis sought to identify mergers and acquisitions advisors’ perceptions of their own negotiation strategies in a typical negotiation. Additionally, the thesis examined the potential association between the first offer and a negotiator’s perception of his or her own negotiation strategy. This was researched empirically by presenting the negotiators two different first offer negotiation scenarios. In the first scenario, a buyer presented a first offer that was higher than a negotiator’s reservation value. In the second scenario, a buyer presented a first offer that was lower than a negotiator’s reservation value. The theoretical framework of the thesis was based on the negotiation analy…

How firm boundaries are drawn

2012

While many studies exist regarding the firm choice to make vs. buy, there has been little study about the choice between make, buy or ally. In this paper we investigate how firms choose among make, buy or make together when they have to organize a particular transaction. In particular we develop theory-based hypothesis that link the theoretical determinants of firm’s boundaries to the governance choice. In order to test such hypothesis we operationalize the main constructs in measurable variables and we collect information for that. The final sample represents 4316 mergers and acquisitions, alliances, and divestitures announced and completed by 88 of the first-ranked 100 members of the 2000…
