Peace-Building without External Assistance: Lessons from Somaliland
Since its secession from Somalia in 1991, the east-African nation of Somaliland has become one of the most democratic governments in eastern Africa. Yet Somaliland has never been recognized by the international community. This paper examines how this lack of recognition—and the consequent ineligibility for foreign financial assistance—has shaped Somaliland’s political development. It finds evidence that Somaliland’s ineligibility for foreign aid facilitated the development of accountable political institutions and contributed to the willingness of Somalilanders to engage constructively in the state-building process.somaliland; post-conflict; peace-building; foreign aid
Flux tubes, visons, and vortices in spin-charge separated superconductors
The idea of spin-charge separation in cuprate superconductors has been
recently energized by Senthil and Fisher who formulated a Z_2 gauge theory and,
within its context, proposed a ``vison detection'' experiment as a test for
topological order in a sample with multiply connected geometry. Here we show
that the same experiment can be performed to test for the spin-charge
separation in U(1) [but not in SU(2)] theory and argue that vortex core
spectroscopy can in fact distinguish between the different symmetries of the
fictitious gauge field.Comment: 3 pages, 1 ps figure. Invited talk at the 13th International

Modeling Infection with Multi-agent Dynamics
Developing the ability to comprehensively study infections in small
populations enables us to improve epidemic models and better advise individuals
about potential risks to their health. We currently have a limited
understanding of how infections spread within a small population because it has
been difficult to closely track an infection within a complete community. The
paper presents data closely tracking the spread of an infection centered on a
student dormitory, collected by leveraging the residents' use of cellular
phones. The data are based on daily symptom surveys taken over a period of four
months and proximity tracking through cellular phones. We demonstrate that
using a Bayesian, discrete-time multi-agent model of infection to model
real-world symptom reports and proximity tracking records gives us important
insights about infec-tions in small populations
Commentary: Blurred lines: Performance Enhancement, Common Mental Disorders and Referral in the U.K. Athletic Population.
Given the personal and sensitive nature of mental disorders, and the stigmas to disclosure that often exist in high performance sport, it was not surprising to learn from Roberts et al. (2016) that the Sport Psychologist, with whom the CMD athlete is likely to have a confidential, trusting, and empathic working relationship, is the person they are most likely to seek out for support. For me, the capacity of the Sport Psychologist to provide the support being sought depends on their competence to both consult with, and refer, athletes with CMD, and the extent to which their own practice philosophy and counseling based training informs their consultancy approach. These two issues form the focus of this commentary
