The determination of nicotine and sulfate in supermarket ground beef adulterated with Black Leaf 40

In December 2002, approximately 250 lbs. of ground beef was adulterated with nicotine sulfate by a supermarket employee and subsequently sold to the public. Soon afterward, reports of illness associated with ground beef purchased at a single store were identified. Authorities suspected the ground beef was tainted with Black Leaf 40, a banned pesticide containing approximately 40% nicotine as nicotine sulfate. Ground beef submitted to our laboratory was analyzed in concert by high performance liquid chromatography-ultraviolet detection (HPLC-UV), gas chromatography-mass spectrometry (GC-MS), and high performance anion exchange chromatography with suppressed conductivity detection. GC-MS was used to identify the samples that contained nicotine. The nicotine was confirmed and quantitated by HPLC-UV. The sulfate was identified and quantitated by high performance anion exchange chromatography with suppressed conductivity detection. Our analysis revealed that the raw tainted beef contained about 350 mg/kg nicotine free base, a potentially lethal dose of nicotine per serving for an adult. Additionally, we found elevated sulfate levels in the samples that tested positive for nicotine, providing evidence that nicotine sulfate was the probable adulterant.     

PC_Eyewitness and the Sequential Superiority Effect: Computer-Based Lineup Administration

Computer technology has become an increasingly important tool for conducting eyewitness identifications. In the area of lineup identifications, computerized administration offers several advantages for researchers and law enforcement. PC_Eyewitness is designed specifically to administer lineups. To assess this new lineup technology, two studies were conducted in order to replicate the results of previous studies comparing simultaneous and sequential lineups. One hundred twenty university students participated in each experiment. Experiment 1 used traditional paper-and-pencil lineup administration methods to compare simultaneous to sequential lineups. Experiment 2 used PC_Eyewitness to administer simultaneous and sequential lineups. The results of these studies were compared to the meta-analytic results reported by N. Steblay, J. Dysart, S. Fulero, and R. C. L. Lindsay (2001). No differences were found between paper-and-pencil and PC_Eyewitness lineup administration methods. The core findings of the N. Steblay et al. (2001) meta-analysis were replicated by both administration procedures. These results show that computerized lineup administration using PC_Eyewitness is an effective means for gathering eyewitness identification data.     

Electricity Market Restructuring and Energy Contracts: A Critical Note on the EU Commission’s NEA Decision

As highlighted in the economic literature, contracts are crucial policy instruments to organize and manage restructured electricity markets. In the early 90’s, during the restructuring of the electricity market in UK, the three main Scottish electricity generators stipulated a long-term, “take-or-pay” contract, the Nuclear Energy Agreement, which contained provisions for the trade of wholesale electricity in Scotland.The European Commission scrutinized such contract in order to derive the congruity of the agreement to European laws. Whilst the NEA was awarded an exemption under Article 85, paragraph 3 of the EU Treaty, the Commission recognized the inner anticompetitive content and potential effects of the contract.In this paper, we criticize the Commission NEA decision and economic reasoning and provide an alternative reading and analytical approach, which lead to opposite results and conclusions (the NEA contract is not anticompetitive and it enhances efficiency in competitive electricity markets). Given that the restructuring process in the EU electricity market is still in fieri, we select the NEA contract as a benchmark-case, in order to provide an alternative reading and a case-study for eventual, future energy contracts administration and authority decisions.JEL K, K2, K230     

Death by sewer gas: case report of a double fatality and review of the literature

Hydrogen sulfide (H2S), the toxic gas associated with the smell of "rotten eggs," is an important cause of work-related sudden death. The gas is particularly insidious due to the unpredictability of its presence and concentration and its neurotoxicity at relatively low concentrations, causing olfactory nerve paralysis and loss of the warning odor. We report a double fatality involving 2 surveyors working near a man-hole, who fell into the sewer and died due to sudden exposure to hydrogen sulfide gas. Key historical, physical, and toxicologic findings are described. Additionally, we present a discussion of the clinical presentations and differential diagnosis, mechanism of injury, metabolism and toxicology, incidence, and scene and safety concerns in fatal hydrogen sulfide exposures.     

Reforming residency: modernizing resident education and training to promote quality and safety in healthcare

The goal of medical residency is to provide the best clinical education for future practice, while increasing quality and safety in current and future healthcare. This goal is not being met. Traditional residency programs often continue to utilize individually oriented, shame-and-blame approaches that do not recognize the systems nature of outcomes, care, and patient safety. Appropriate substantive methods, content, and training tools are also lacking, while residents continue to labor in a poor working environment. All these factors create a system that serves no one-not the resident, the patient, or the system in which both interact. Residency reforms are proposed to address these imperative concerns.     

Selfless androgyny: Gregory Rose as ‘virile woman’ in Olive Schreiner's the story of an African farm

While Lyndall, the feminist heroine of Olive Schreiner's The Story of an African Farm, articulates and enacts a critique of the position of women in male-dominated society, Gregory Rose's transformation from a vain and self-centred man into a nurturing female nurse is an important part of Schreiner's feminist vision. His womanhood both complements and critiques Lyndall's ‘virility,’ allowing Schreiner to present a fictional version of her theoretical ideal of selfless androgyny.     

Characteristics of married and unmarried adolescent mothers and their partners

In a middle-class, urban-clinic sample of 275, mostly Caucasian, adolescent mothers and their partners living in Utah, three groups were identified and their psychosocial characteristics were compared. Couples married at the time of conception (N=22) enjoyed more positive responses from prospective grandparents and earned more than couples not married at the time of conception. On the other hand, these initially married youths were much more likely to be high-school dropouts, which suggests limits in their lifetime earning capacities, and they were not more likely to identify one another as sources of emotional support. Couples who married between conception and delivery (N=110) reported that prospective grandparents responded less favorably to news of the pregnancy than did relatives of the initially married couples, but while their current salaries were lower, they were much more likely to be continuing with their education. Those who married after conception also had fewer antisocial and conduct disorders than young men and women who chose to continue in a dating relationship (N=29). Overall, the couples who married after conception appeared to face less severe problems than either the initially-married couples or the steady daters.This research was supported by grant number APR 000922-02-0 from the Office of Adolescent Pregnancy Programs to Drs. Elster and Lamb.where he and Dr. Lamb conduct research on pregnant teens, teenaged parents, and their children.

Mixing God's Work and the Public Business: A Framework for the Analysis of Faith‐Based Service Delivery

Over the past thirty years, there has been a dramatic transformation in the way the American political process operates. There has been a growing public perception that traditional political institutions lack the capacity to meet existing challenges. This has led many observers to call for a rethinking of how government does its work. Numerous alternatives, including the use of faith‐based organizations, have been suggested. The current popular debate on the appropriate role of faith‐based organizations in public service delivery has shed little light on a number of important issues raised by engaging such actors in governance issues. The impact of using faith‐based institutions to design and implement public policy must be considered not only in terms of traditional evaluation standards, but also regarding potential long‐term impacts on the political process itself. This article outlines a theoretical framework for the evaluation of faith‐based organizations as “alternatives” to conventional governance structures. It identifies key practical and theoretical issues raised by such substitution, in both short and long range systemic terms.
