Ink dating part II: Interpretation of results in a legal perspective

The development of an ink dating method requires an important investment of resources in order to step from the monitoring of ink ageing on paper to the determination of the actual age of a questioned ink entry. This article aimed at developing and evaluating the potential of three interpretation models to date ink entries in a legal perspective: (1) the threshold model comparing analytical results to tabulated values in order to determine the maximal possible age of an ink entry, (2) the trend tests that focusing on the “ageing status” of an ink entry, and (3) the likelihood ratio calculation comparing the probabilities to observe the results under at least two alternative hypotheses. This is the first report showing ink dating interpretation results on a ballpoint be ink reference population.In the first part of this paper three ageing parameters were selected as promising from the population of 25 ink entries aged during 4 to 304 days: the quantity of phenoxyethanol (PE), the difference between the PE quantities contained in a naturally aged sample and an artificially aged sample (R_NORM) and the solvent loss ratio (R%). In the current part, each model was tested using the three selected ageing parameters. Results showed that threshold definition remains a simple model easily applicable in practice, but that the risk of false positive cannot be completely avoided without reducing significantly the feasibility of the ink dating approaches. The trend tests from the literature showed unreliable results and an alternative had to be developed yielding encouraging results. The likelihood ratio calculation introduced a degree of certainty to the ink dating conclusion in comparison to the threshold approach. The proposed model remains quite simple to apply in practice, but should be further developed in order to yield reliable results in practice.     

The Shard Box Store

People have been creating ceramics in the lands that now make up China for 20,000 years. The pottery discovered in caves in southeast China's Jiangxi Province is among the oldest examples found anywhere in the world, and iluminates the origins of one of China's most signiif cant art forms. Chinese earthenware came to resemble what we might today cal porcelain sometime around the Han Dynasty (202 B.C.-A.D. 220), with techniques honed throughout the dynastic period to reach a level of refinement which saw Chinese pots, vases and bowls become some of the most coveted objects in the world.     

The main factors of repetition: review of some results of the Pecs Center in the WHO/EURO Multicentre Study on Suicidal Behaviour

The authors obtained more information about the characteristics of suicide attempters in order to examine the most important differences between those who attempted suicide for the first time (first-evers) and those who had a previous attempt (repeaters). Within the framework of the WHO/EURO Multicentre Study on Suicidal Behaviour in Pecs Center, 1158 cases of parasuicide were collected over 4 years (July 1, 1997-June 30, 2001). In the monitoring sample, 728 (62.9%) parasuicide acts were committed by women and 430 (37.1%) by men, and more than half of the attempters had made a previous attempt In the logistic regression model a higher risk of repetition was found to be related to being divorced (OR 1.84), unemployed or economically inactive (OR 1.45), and without higher education (OR 2.54). In the sample, mental disorders were the most significant risk factor for repeated attempts. The odds ratio was highest (OR 5) for personality disorders. The results may reflect (besides some factors of social destabilization) a higher importance of major mental health problems among repeaters. For this reason, more effective recognition and treatment of the underlying psychiatric and social conditions of suicide attempters has special importance to prevent future suicidal behaviour.     

Juveniles' Competence to Stand Trial: A Comparison of Adolescents' and Adults' Capacities as Trial Defendants

Abilities associated with adjudicative competence were assessed among 927 adolescents in juvenile detention facilities and community settings. Adolescents' abilities were compared to those of 466 young adults in jails and in the community. Participants at 4 locations across the United States completed a standardized measure of abilities relevant for competence to stand trial (the MacArthur Competence Assessment Tool—Criminal Adjudication) as well as a new procedure for assessing psychosocial influences on legal decisions often required of defendants (MacArthur Judgment Evaluation). Youths aged 15 and younger performed more poorly than young adults, with a greater proportion manifesting a level of impairment consistent with that of persons found incompetent to stand trial. Adolescents also tended more often than young adults to make choices (e.g., about plea agreements) that reflected compliance with authority, as well as influences of psychosocial immaturity. Implications of these results for policy and practice are discussed, with an emphasis on the development of legal standards that recognize immaturity as a potential predicate of incompetence to stand trial.     

The Competence-Related Abilities of Adolescent Defendants in Criminal Court

Increasing numbers of youths are being tried in criminal court because of statutory measures that have decreased the use of judicial review as the primary mechanism for transfer. The relative immaturity of adolescents suggests that transferred youths might have impaired competence-related abilities compared to adults. To test this hypothesis, we compared the competence-related abilities and developmental characteristics of a sample of direct-filed 16-17-year-olds charged in criminal court in the state of Florida (Direct File sample) to a sample of 18-24-year-old adults charged in criminal courts (Adult Offender sample) and to a separate sample of 16-17-year-olds charged in juvenile court (Juvenile Court sample). Results indicated that there were few differences between the Direct File youths and Adult Offenders. The differences that were observed suggested that the Direct Filed youths performed slightly better than the Adult Offender group and the Juvenile Court youths charged in juvenile court. These findings suggest that as a group, 16-17-year-old Direct File adolescents do not have significant deficits in competence-related abilities due to age or immaturity.     

Belief in a Just World and Commitment to Long-Term Deserved Outcomes

We investigated whether people need to believe in a just world in part because such a belief helps people to work toward long-term goals and to do so in such a way that they are deserved. We assessed participants' long-term goal focus and also their commitment to deserving their outcomes (via a psychopathy scale). In a second session, participants were then exposed to a victim whose situation did or did not contradict a belief in a just world. When the victim's situation contradicted a belief in a just world, the greater the participants' tendency to focus on long-term outcomes, the more they blamed the victim for her misfortune; but this relation only occurred for participants with a strong commitment to deserving their outcomes (i.e., those low in psychopathy). The results are consistent with our argument that, given the function of the belief in a just world proposed in this article, people would have a greater need to preserve the belief (e.g., by blaming victims of injustice) the greater their investment in long-term and deserved outcomes.     

Time periods of GSR particles deposition after discharge-final results

The elemental objects of the research study are: determination of time periods corresponding to gunshot residue particles (GSR) deposition after the shot from selected pistols and a revolver, and evaluation of the deposited particles number. For several shooting experiments were used a pistol CZ model 85, caliber 9 mm Luger with common ammunition 9 mm Luger FMJ Sellier & Bellot, a pistol CZ model 70, caliber 7.65 mm Browning (32 ACP) with common 7.65 mm Browning FMJ Sellier & Bellot ammunition and a revolver S&W Modell 60, barell length 2-1/8', cal. .38 Special with common Sellier&Bellot (FMJ) ammunition. The results of the study have indicated the behavior of GSR particles deposited after a single discharge. The overall time interval of GSR particles deposition and the number of deposited particles with the above mentioned arms and ammunition were established. The results can potentially be used for clarifying the situation at crime scenes and for subsequent interpretation of GSR evidential value in caseworks.
