Propagation of QCD Color through Strongly Interacting Systems

The propagation of QCD color through atomic nuclei is studied via a new analysis using a geometric model of semi-inclusive deep inelastic scattering. The experimental data were previously published by the HERMES Collaboration and consisted of the multiplicity ratio observable (2007) and the transverse momentum broadening observable (2010). We perform a simultaneous fit of these two observables to estimate (1) the color lifetime of the quark, (2) quark energy loss, (3) the $\hat{q}$ transport coefficient, and (4) the cross section for hadronic interaction with the medium. We present preliminary results for this fit.Comment: 4 pages, 3 figures; proceedings for the Eighth International Conference on Quarks and Nuclear Physics (QNP2018), Tsukuba, Japan. https://www-conf.kek.jp/qnp2018

Underpricing, Risk Management, Hot Issue and Crowding out Effects: Evidence from the Australian Resources Sector Initital Public Offerings

In this paper, we provide a comprehensive investigation of 260 initial public offerings (IPOs) in the Australian resource sector for the 1994 – 2004 period. Consistent with the existing IPO literature, we document a 16.13% underpricing return by firms in the sample. Despite the contention that risk management can reduce the uncertainty relating to the new issue and hence alleviates the extent of underpricing, we do not find any evidence in support of such contention. In addition to the conventional variables used to explain IPOs underpricing, we further provide evidence that the demand for resources IPOs is not ‘crowded-out’ by the strength of alternative IPO markets. We also show evidence that the issue price adjusts to both market return in preceding months and the average underpricing of resources IPOs in the 12 month period leading to the float which offers an explanation to the hot issue effect observed in the IPO market.initial public offerings, underpricing, risk management, crowding-out effect, hot issue market.

The Privatization of the Civil Commitment Process and the State Action Doctrine: Have the Mentally Ill Been Systematically Stripped of Their Fourteenth Amendment Rights?

The Supreme Court has recognized that civil commitment constitutes a significant deprivation of liberty that requires due process protection. A state\u27s ability to commit the mentally ill is subject to the due process limitations of the Fourteenth Amendment. However, the circuit courts have held that civil commitment by private physicians to private hospitals does not constitute state action for Fourteenth Amendment purposes. The author proposes that the state action doctrine extend to civil commitment by private physicians, and criticizes federal decisions that have held otherwise
