DNA forensics and the poaching of wildlife in Italy: a case study

DNA molecular techniques were used in a forensic investigation involving the poaching of wildlife in a national park of Italy. A poacher, after having snared a wild boar (Sus scrofa) sow, knifed it to death. The animal was retrieved by conservation officers at the scene before the poacher could remove the carcass. Subsequently, the suspect denied the charges. During a search of his home, a bloodstained knife was confiscated. A method to identify the species from the DNA extracted from the stains revealed the blood to be that of the non-domestic form of Sus scrofa. Further DNA typing for individual identity using species-specific single tandem repeats or microsatellites (STRs) showed that the DNA on the knife matched that of the poached boar. Based upon the forensic evidence obtained, the suspect was convicted of poaching and of cruelty to animals.     

The forensic analysis of thermal transfer printing

Thermal transfer printing refers to printing processes that utilize heat to produce an image by either physical or chemical means or by a combination of both. As the technology has improved and the supplies have become less expensive, the use of thermal printing in the personal and business markets has increased significantly. Specifically, dye diffusion thermal transfer and thermal mass transfer have become predominant in the production of counterfeit credit cards, drivers' licenses, and other types of documents produced on plastic media. Chemical analysis by means of thin layer chromatography (TLC) has proven to be useful in characterizing various types of inks (e.g., writing and inkjet inks). In this study, the authors examined 81 different samples that included a total of 54 printer samples (43 photographic prints on paper and eleven plastic card samples) and 27 printer ribbons. A new TLC method was developed and tested utilizing a solvent system (80% n-hexane, 3% methyl ethyl ketone, and 17% ethyl acetate) that is capable of producing excellent resolution.     

Juror Judgments in Civil Cases: Hindsight Effects on Judgments of Liability for Punitive Damages

An experiment was conducted to investigate whether hindsight bias influences an important class of legal decisions—civil jurors' judgments of liability for punitive damages. Jury-eligible citizens were shown a videotaped summary of the circumstances surrounding an environmental damage lawsuit. Some subjects were presented a foresight perspective and asked to judge whether or not a railroad should comply with an order to stop operations on a section of track that had been declared hazardous. Other subjects were asked to judge whether the railroad was liable for punitive damages after an accident occurred. Three independent variables were manipulated: temporal perspective with one third of the subjects assessing risks in foresight and two thirds assessing risks in hindsight; subject role with one half of the subjects asked to assume the role of a juror rendering a verdict and one half the role of a citizen whose personal opinion was solicited; and, in the hindsight conditions only, the amount of damage ($240,000 vs. $24,000,000) caused by the accident. Almost all measures of participants' judgments and thoughts about the case showed dramatic foresight–hindsight differences. The participants' role had an effect on some measures; for example, participants in the juror role exhibited slightly smaller hindsight effects when judging liability than did those in the citizen role. The magnitude of the damage caused by the accident had no effects on any measures.     

Juror Judgments in Civil Cases: Effects of Plaintiff's Requests and Plaintiff's Identity on Punitive Damage Awards

Two experiments were conducted to study the manner in which civil jurors assess punitive damage awards. Jury-eligible citizens were shown a videotaped summary of an environmental damage lawsuit and told that the defendant had already paid compensatory damages. They were asked to judge liability for punitive damages and, if damages were to be assessed, to assign a dollar award. Three independent variables were manipulated in the case materials: the dollar amounts that were explicitly requested by the plaintiffs in their closing arguments to the jury, the geographical location of the defendant corporation, and the location of the lead plaintiff. Consistent with prior findings of anchor effects on judgments, we found that the plaintiffs requested award values had a dramatic effect on awards: the higher the request, the higher the awards. We also found that local plaintiffs were awarded more than were geographically remote plaintiffs, while the location of the defendant company did not have reliable effects on the awards. The implications of these results for procedures in civil trials and for theories of juror decision making are discussed.     

IMPLEMENTING COMPARABLE WORTH IN THE PUBLIC SECTOR: THEORY AND PRACTICE AT THE STATE AND LOCAL LEVEL

This paper defines comparable worth as part of the pay equity movement, given an overview of the reasons for its development in the 1980s.and identifies objections to its implementation. It also articulates the political and implementation challenges comparable worth presents and specifies the purpose of this special symposium.     

Y-chromosome lineages in São Tomé e Príncipe and Cabo Verde islands: Different input of European influence

The Y-chromosome haplogroup composition of the population of São Tomé e Príncipe and Cabo Verde Archipelagos was profiled by using 24 biallelic markers, and compared with populations from Europe, Africa and the Middle East. According to the traditional view, these archipelagos colonized by the Portuguese in the 15th century were settled mainly by West African slaves, with the addition of a minor fraction of male colonizers from Europe. Although the major proportion of the founding population of São Tomé e Príncipe cluster in haplogroup E3a (84.2%), very common among sub-Saharans, this lineage was observed at a frequency of only 15.9% in Cabo Verde. Haplogroups I, J and R1, characterized of populations of Europe and the Middle East account for more than half of the paternal lineages of Cabo Verdeans (53.5%). These West Eurasian haplogroups are found at a frequency of only 12.5% in the population of São Tomé e Príncipe. Our findings suggest that despite the sub-Saharan genetic background of these archipelagos, a relevant contribution of European paternal lineages is present in nowadays populations indicating that gene flow from multiple sources have been important in the formation of the diversity of the islanders, nevertheless with a different degree of admixture.
