Digital Expungement

Digital technology might lead to the extinction of criminal rehabilitation. In the digital era, criminal history records that were expunged by the state remain widely available through commercial vendors (data brokers) who sell this information to interested parties, or simply through a basic search of the Internet. The wide availability of information on expunged criminal history records increases the collateral consequences a criminal record entails, thereby eliminating the possibility of reintegration into society. Acknowledging the social importance of rehabilitation, policymakers attempted to regulate the practices of data brokers by imposing various legal obligations and restrictions, usually relating to the nature and accuracy of criminal records and the purposes for which they may be used. These regulations have been proven insufficient to ensure rehabilitation. But regardless of future outcomes of such regulatory attempts, policymakers have largely overlooked the risks of the Internet to expungement. Many online service providers and hosting services enable the wide dissemination and accessibility of criminal history records that were expunged. Legal research websites, websites that publish booking photographs taken during investigation (mugshots), social media platforms, and media archives all offer access to expunged criminal histories, many times without charge, and all with the simple use of a search engine. Without legal intervention, rehabilitation in the digital age in the U.S. has become nearly impossible. This Article offers a legal framework for reducing the collateral consequences of expunged criminal records by offering to re-conceptualize the public nature of criminal records. It proceeds as follows. After an introduction, Part II examines rehabilitation and expungement as facets of criminal law. Part III explores the challenges of digital technology to rehabilitation measures. Part IV evaluates and discusses potential ex-ante and ex-post measures that could potentially enable rehabilitation in the digital age. It argues that while ex-post measures are both unconstitutional and unrealistic for enabling digital expungement, ex-ante measures could be a viable solution. Accordingly, this Article suggests implanting a graduated approach towards the public nature of criminal history records, which would be narrowly tailored to serve the interests of rehabilitation-by-expungement. Finally, the last Part concludes the discussion and warns against reluctance in regulating expunged criminal histories

Two-Loop Radiative Corrections to the Lightest Higgs Boson Mass in the Minimal Supersymmetric Model

In the minimal supersymmetric model (MSSM), the upper limit of the lightest Higgs boson mass, \mhl, depends strongly on the top quark mass, $m_t$. We have computed the dominant two-loop radiative corrections to this upper limit of \mhl in order to eliminate large uncertainties due to QCD and $m_t^6$ corrections. It is shown that the QCD corrections significantly reduce the one-loop corrections. As a result, the SUSY parameter space accessible to LEP experiments is significantly increased.Comment: 14 pages using PHYZZX, 4 figs. are appended as PS-file

A Century of Synthetic Fertilizer: 1909-2009

This year marks a centenary of the synthetic fertilizer industry. German chemists, Fritz Haber and Carl Bosch, in 1909 demonstrated their industrial process for the manufacture of ammonia. The achievement won them accolades including Nobel Prizes. The output of their Haber-Bosch process can be used for either peace or war, agriculture or munitions, and the rapid adoption by Germany of this industrial process is credited with prolonging WW1. Most of the synthetic nitrogenous fertilizer of the past century, and right up to the present, has been manufactured using the Haber-Bosch process. The use of synthetic fertilizers has led to significant negative environmental outcomes. Rudolf Steiner was an early voice against chemical agriculture. Steiner's Agriculture Course of 1924 led to the development and world-wide proliferation of Bio-dynamic Agriculture, a farming system which has always championed the biological fixation of nitrogen by soil micro-organisms. This paper identifies ten key differences between biological and Haber-Bosch chemical fixation of nitrogen
