The Right to Die Debate is a recent but highly controversial moral matter. In particular, physician-assisted suicide (PAS) is an issue that has been evaded by the medical community for years. As of 1990, most states had never encountered the issue before and therefore did not have any laws in place to prohibit PAS (Strate et. al, 2005). Dr. Jack Kevorkian, a retired pathologist from Royal Oak Michigan was the first to publicly address PAS. He brought the issue into the limelight through a bizarre and crude series of assisted deaths that had a lasting impact on not only the Right to Die Debate as whole, but on public policy and both federal and state governmental agendas. This study focuses on the way in which the media, in particular the New York Times (NYT) has portrayed Dr. Jack Kevorkian as incompetent, morally culpable and in an overall negative light in the past twenty years. Applying Stanley Cohen’s 1972 theory of moral panic, a content analysis of NYT media publications between 1990 and 1999 supports Cohen’s theory and reveals that the media has created a moral panic surrounding Kevorkian. This has in turn led to public policy that prevents both terminally ill individuals and their doctors from having a desirable choice; that of voluntary euthanasia and PAS.

Few studies have directly related turfgrass growth and quality responses to extractable soil P concentrations in sand greens. A 3-yr field experiment was conducted on a sand-based putting green to determine creeping bentgrass (Agrostis stolonifera L.) growth and quality responses to extractable soil P. Extractable soil P concentrations were obtained by using the modified-Morgan, Mehlich-1, and Bray-1 extractants. Critical extractable P concentrations (above which there is a low probability of response to increasing soil P concentrations) for shoot counts, thatch thickness, relative clipping yields, quality ratings, P deficiency ratings, tissue P concentrations, and root weights were determined using Cate-Nelson (CN) and quadratic response and plateau (QRP) models. Both models fit the data relatively well in most cases (R2 values from 0.12 to 0.89), and critical concentrations for the QRP models were always greater than the CN models. Critical extractable P concentrations were lowest for the modified-Morgan extractant (1.4 to 12.0 mg kg(-1)) and greatest for the Mehlich-1 extractant (14.1 to 63.6 mg kg(-1)). Application of estimated critical extractable P concentrations in this study could be used to substantiate observed responses or explain lack of responses in other previously reported creeping bentgrass P studies. We found better model fits with modified-Morgan extractable P for bentgrass quality ratings, deficiency ratings, and tissue P concentrations than with P extracted by the Mehlich or Bray methods. This suggests that the modified-Morgan extractant may have advantages over stronger-acid extractants when used on sand-based media. The results can be used to revise or update existing P fertilization recommendations for bent-grass grown on sand-based media.
