The Culprit in Target-Absent Lineups: Understanding Young Children’s False Positive Responding

Young children (4- to 7-years old; N = 59) and adults (N = 53) were shown a series of targets that were either familiar (i.e., popular cartoon characters) or unfamiliar (unknown human faces) to assess whether children’s false positive responding with target-absent lineups is driven by social factors to a greater degree than cognitive factors. Although children were able to produce correct identification rates with virtually 100% accuracy for the cartoon characters, they produced a significantly lower correct rejection rate compared to adults. Children also produced a significantly lower correct rejection rate for the human faces compared to adults. These data are discussed for understanding children’s identification evidence.     

Does Lineup Size Matter with Child Witnesses

Children’s (N = 89) identification accuracy was examined as a function of lineup size. Participants (8–13 years) viewed a videotaped staged event, described what was witnessed and then were presented with either a target-present or—absent lineup containing 6 versus 12 lineup members. The elimination lineup procedure (Pozzulo and Lindsay J Appl Psychol 38: 2195–2209 1999) was used to present lineups. No significant differences in correct identification rates were found across the target-present sized lineups. In addition, the target was likely to “survive” at a comparable rate regardless of lineup size. Moreover, there was no significant difference in correct rejection rate as a function of lineup size. The non significance of these data are critical given that most research with child witnesses uses 6-person lineups whereas in many real world contexts larger sized lineups are used (e.g., 12-person in Canada).     

Metropolitan Planning Organizations: Findings and Recommendations for Improving Transportation Planning

With the enactment of the Intermodal Surface TransportationEfficiency Act in 1991, metropolitan planning organizations(MPOs) became more important institutions for planning and fundingregional transportation systems. This study attempts to assessthe success of MPOs in four fast-growing areas- Dallas/Ft. Worth,Denver, Phoenix, and Seattle-in meeting regional transportationneeds. The research identifies the criteria that distinguishmore successful from less successful MPOs-effective leadership,staff competence and credibility, quality public involvement,development of a regional ethos, streamlined and efficient processes,cooperative relationships with the state DOT, land-use coordination,and accountability to members–and offers suggestions forimproving transportation planning.     

The Nature and Effect of the Anglo-Saxon Vernacular Will

Scotland took its time in abolishing irregular marriage. While the Roman Catholic Church stopped recognising irregular forms in 1563, and England followed suit two hundred years later with Lord Hardwicke's Act of 1753, Scotland retained the medieval canon law of irregular marriage until 1940. This article exposes the various interests lobbying for reform of the law of formation of marriage in Scotland during the 1920s and 1930s and the assertions and arguments they employed and reveals the main factors which resulted in the success of this lobbying at this particular point in time: the influence and attitude of the Church of Scotland, and, echoing the scandal of Fleet marriages in England before the 1753 Act, the availability of circumstances at Gretna Green which could be portrayed as a scandal.

Enzymatic detection of γ-hydroxybutyrate using aldo-keto reductase 7A2

Gamma-hydroxybutyrate (GHB) is a prescribed medication as well as a drug of abuse. Its detection in various matrices for in-field forensic scientists remains a challenge. We have developed an assay that uses aldo-keto reductase 7A2 (AKR7A2) for the specific determination of GHB in various drinks. AKR7A2 was purified using Ni-affinity chromatography. The Michaelis-Menten constant for the GHB oxidation reaction was 10 mM, and the minimum detection limit was 4 mM. Ethanol was not a substrate for AKR7A2. In a coupled reaction with NADP(+), phenazine methosulfate (PMS), and 2,6-dichlorophenolindophenol, various beverages (orange juice, milk, soda, and numerous alcoholic drinks) containing GHB turned from blue to light yellow. In a second coupled reaction where diaphorase replaced PMS, the presence of GHB also caused the expected change of color in various beers.
