Who do you believe? Assessing student and community member perceptions of bystander and victim witnesses

ABSTRACT

Eyewitness identifications provide critical evidence as they are often persuasive to jurors, but documented misidentifications have led to wrongful convictions . Researchers have examined how jurors evaluate multiple eyewitnesses, but not different types of eyewitnesses, such as bystanders and victims. Additionally, none of this research has examined jurors’ ability to evaluate bystander and victim identifications that vary in quality. Two studies examined student and community members’ perceptions of bystander and victim witnesses. Study 1 participants read about a good or poor-quality identification made by a bystander or victim. Study 2 participants read about both bystander and victim identifications that varied in quality. Both studies found jurors were sensitive to identification quality as demonstrated by a variety of legal decisions, including verdict, though the quality of a second identification in Study 2 did not change any legal decisions. Multiple differences between student and community member samples emerged across both studies suggesting that community members are more likely to trust witnesses and convict. Reliance on student samples may overestimate jurors’ ability to evaluate multiple eyewitnesses and underestimate the likelihood of conviction based on flawed eyewitness evidence.     

A commentary on strategic land promotion in the UK

The supply of land for new housing within the UK is an important and a contested issue. Strategic land promotion, namely, the identification, acquisition, and promotion of land through the planning system, has become a major element in contributing to government targets for new housebuilding in the UK. This brief commentary paper outlines the characteristics of strategic land promotion, provides illustrations of the range of schemes land promotion companies have pursued within the UK, and concludes with some wider reflections on the process.     

Like Talking to a Brick Wall: Implications of Emotion Metaphors for Mediation Practice

In this article, the authors discuss the role of emotions in mediation with the goal of providing practical insights that can improve the mediation process. Their assumption is that emotion is ever-present, particularly in conflict, and that acknowledging and addressing underlying emotions facilitates conflict transformation during the mediation process.     

Gas chromatographic/mass spectrometric analysis of morphine and codeine in human urine of poppy seed eaters

In this study, poppy seeds were examined for a natural constituent that might serve as a maker for the seeds' ingestion as opposed to opiate abuse. Thebaine was selected as possible marker, since it was found to be a component of all poppy seeds examined and was not a natural component of different heroin samples. During the course of this investigation, a new extraction and cleanup procedure was developed for the gas chromatographic/nitrogen phosphorus detection (GC/NPD) and gas chromatographic/mass spectrometric (GC/MS) analysis of morphine and codeine in urine. A linear response, over a concentration range of 25 to 600 ng/mL, was obtained for codeine and morphine (r = 0.9982 and 0.9947, respectively). The minimum detectable level (LOD) and limit of quantitation (LOQ) for morphine were 10 and 30 ng/mL, respectively; whereas LOD and LOQ for codeine were 2 and 8 ng/mL, respectively. The coefficients of variance (CV, n = 6) for morphine and codeine analyses at the 100-ng/mL level were 13.3 and 4.6%, respectively. This procedure was used for the analysis of urine samples from five poppy seed eaters who each ingested 200 g of poppy seed cake. Results indicated that significant amounts of morphine and codeine are excreted in urine and that in all subjects, at least at one point in time, the apparent morphine concentration as determined by radioimmunoassay (RIA) analysis exceeded the cutoff value (300 ng/mL) established for screening. Thebaine was not detected in urine specimens collected following poppy seeds ingestion and thus could not be used as a marker.     

Evaluation of a nonequilibrium isoelectric focusing (IEF) method for the simultaneous typing of esterase D (EsD), red cell acid phosphatase (AcP1), phosphoglucomutase (PGM1), adenylate kinase (AK), and adenosine deaminase (ADA)

A nonequilibrium isoelectric focusing method incorporating the chemical spacers MOPS and HEPES was developed and subsequently evaluated for its ability to reliably discriminate common and rare phenotypes in the esterase D (EsD), red cell acid phosphatase (AcP1), phosphoglucomutase (PGM1), adenylate kinase (AK), and adenosine deaminase (ADA) isoenzyme systems. The validation procedures used were blind testing, comparison of results to conventional methods, and evaluation of known rare variant phenotypes. This method proved to be a quick and reliable method for typing all five isoenzyme systems, while providing an excellent probability of discrimination (PD = 0.96).     

Rechtliche Anforderungen an die Eingriffsbilanzierung und deren naturschutzfachliche Umsetzung am Beispiel von Abgrabungsvorhaben

Zur naturschutzfachlichen Bewertung und Bilanzierung von Eingriffen in Natur und Landschaft sind seit der Einführung der naturschutzrechtlichen Eingriffsregelung im Jahre 1976 durch Wissenschaft und Praxis zahlreiche Bewertungs- und Bilanzierungsverfahren entwickelt worden, deren praktische Anwendung jedoch nach wie vor erhebliche rechtliche Probleme aufwirft. Diese resultieren unter anderem daraus, dass zur Ermittlung der mit einem Eingriff verbundenen Beeinträchtigungen häufig ausschließlich auf—zufällige—aktuelle faktische Gegebenheiten und deren Wirkungen auf Natur und Landschaft (Ist-Zustand) abgestellt wird. Der Beitrag weist nach, dass diese Vorgehensweise in bestimmten Fallgestaltungen den Grundprinzipien der naturschutzrechtlichen Eingriffsregelung zuwiderlaufen kann, und zeigt für diese Fallgestaltungen rechtskonforme naturschutzfachliche Lösungsmöglichkeiten auf. *) Die Verfasserin ist Mitarbeiterin der Anders u.
