Screening for barbiturates in vitreous humor by the EMIT-st serum enzyme immunoassay

In 16 medical examiner's cases, which were found to be barbiturate-positive by thin-layer chromatographic screening of the liver, blood barbiturate concentrations were determined by gas chromatography. The corresponding vitreous humor samples were screened by the enzyme multiplied immunoassay technique, the EMIT-st serum barbiturate assay. By using the recommended dilution for detecting serum barbiturates, it was possible to detect barbiturates in vitreous humor at a toxic concentration. By using one fourth the amount of diluent, the barbiturates could be detected also at a therapeutic concentration. The EMIT-st assay proved to be useful in the screening for barbiturates in vitreous humor, a material that is readily available in forensic toxicology.     

What We Have Learned About Teaching Multiparty Negotiation

This article grows out of our experience teaching an advanced course on multiparty negotiation. The main question underlying the course is: “How can experts in two‐party negotiations make themselves effective multiparty negotiators?” In this article, we describe what and how we taught, what we think worked, and what we decided to change after the first year of teaching.     

Underwriters' counsel as gatekeeper or turnstile: an empirical analysis of law firm prestige and performance in IPOs

The first 150 words of the full text of this article appear below. Key points

• The article investigates the relationship betweenpricing in an initial public offering (IPO) and the prestigeof the participating underwriters’ law firm.
• The hypothesisof the article is that law firm quality affects how law firmsperform their obligations in IPOs—more prestigious lawfirms acting more independently. Consistent with this hypothesis,the authors find a negative relationship between pre-IPO priceadjustment and the participation of prestigious underwriters’counsel, and a negative relationship between the participationof prestigious underwriters’ counsel and initial return,which is consistent with market trading reflecting the decreasedrisk associated with offerings involving prestigious underwriters’counsel.
• Finally, it is found that certain observable characteristicsindicating diminished likelihood of undisclosed negative information(venture backing and quality of the issuer's counsel) are associatedwith an increased likelihood that prestigious underwriters’counsel is used.
