The Contribution of D. K. Wilgus to Ballad and Folksong Scholarship

Note on SU(2) isolated horizon

“…This was accomplished, about a decade after those earlier works, in [13]. Notably, it came with an interesting twist.…”

“…Notably, it came with an interesting twist. In the symplectic structure for the SU (2) case [13], the prefactor in front of the contribution from the IH, differed from that of the U (1) case [27]. While in the U (1) scenario it was only the area of the IH [27], in the SU (2) case it was the area of the IH divided by (1 − γ 2 ) [13].…”

“…Although the introduction of such variables has provided us with a viable quantum theory for real and positive values of γ, nevertheless, it is a very well known fact that the SAIB gauge field acts as a connection only on a spatial slice; it can not be interpreted as the pullback of a spacetime connection on a slice unless γ = ±i [6]. In spite of this feature of the SAIB connection, the available theory of LQG has been founded on the SAIB connection only for real and positive values of γ [1,2], which has set the stage for black hole entropy calculation [7][8][9][10][11][12][13][14][15][16]. The novelty of the framework lies in the fact that it gives a clear path from the classical to the quantum theory, leading to the Hilbert space structure of the black hole horizon and hence, counting of states.…”

“…Also, the SS diverges for σ 2 = (1 + γ 2 ) −1 implying that the full symmetry of an SU (2) IH is not retained. Above that, any other choice of a particular value of the parameter, like the one made in [13], provides a fixed relationship between the local Lorentz boosted frame and the foliation of the IH which violates the symmetries of an IH even if we restrict to the condition σ 2 = (1 + γ 2 ) −1 . We offer some remarks on the entropy calculation under this restriction.…”

Between rhetoric and reality: exploring the impact of military humanitarian intervention upon sexual violence – post-conflict sex trafficking in Kosovo

“…Evidence can be found in the statements issued by the UN Secretary-General in relation to Rwanda and Kosovo, General Assembly resolutions regarding interventions throughout the 1990s, and the general support of the international community with regard to the interventions in Kosovo and East Timor. 13 Nesiah describes the partnership between certain feminists and 'military hawks' as forming a 'marriage' of convenience between the two entities that has, since Bosnia, been further demonstrated in justifications for interventions in Afghanistan and Iraq. 10 In response to criticism by legal scholars regarding the dubious legal justifications for NATO's intervention, Secretary-General Kofi Annan stated: '[T]he genocide in Rwanda will define for our generation the consequences of inaction in the face of mass murder … If … a coalition of States had been prepared to act in defence of the Tutsi population, but did not receive prompt Council authorization, should such a coalition have stood aside and allowed the horror to unfold?'…”
