Introducing 3D Printed Models as Demonstrative Evidence at Criminal Trials

This case report presents one of the first reported uses of a 3D printed exhibit in an English homicide trial, in which two defendants were accused of beating their victim to death. The investigation of this crime included a micro‐CT scan of the victim's skull, which assisted the pathologist to determine the circumstances of the assault, in particular regarding the number of assault weapons and perpetrators. The scan showed two distinct injury shapes, suggesting the use of either two weapons or a single weapon with geometrically distinct surfaces. It subsequently served as the basis for a 3D print, which was shown in court in one of the first examples that 3D printed physical models have been introduced as evidence in a criminal trial in the United Kingdom. This paper presents the decision‐making process of whether to use 3D printed evidence or not.     

Serum alcohol concentrations in trauma patients determined by immunoassay versus gas chromatography

There has been an extensive discussion in the forensic toxicology community regarding the effect of trauma on the enzymatic method for ethanol analysis. There is a paucity of information in the literature that addresses this question. This study was designed to compare the Dade Behring Dimension enzymatic method with the reliable gas chromatographic method. The blood samples collected at the same time from trauma patients were analyzed by both methods. The result of the study shows no significant quantitative difference between the enzymatic and gas liquid chromatographic (GLC) methods. Also, the enzymatic method did not show any false positive ethanol in cases where the GLC method showed a negative finding.     

THE POLITICS OF DEFENSE POLICY COMMUNICATION: THE "THREAT" OF SOVIET STRATEGIC DEFENSE

This paper suggests a technique for evaluating threat assessments when reliable data is unavailable. Previously, scholars have found that political leaders manipulated threat assessments to achieve desired defense policy outcomes. Yet contemporary communication about threats are not easily studied, leading some writers to call for new studies of Clausewitz's so-called "social" dimension of strategy – the efforts by governments to assure domestic support for defense policies. To apply the suggested technique, this paper examines the Reagan Administration's claim that the threats from Soviet strategic defenses justify the U.S. Strategic Defense Initiative. The Administration's arguments are found to be unclear and internally inconsistent. Despite some fear appeals about Soviet threats, Reagan officials typically noted that American offensive forces will continue to render Soviet defenses impotent and obsolete for the forseeable future. Indeed, vague and inconsistent statements about Soviet forces may have undermined Administration efforts to fulfill SDI funding goals, to codify early deployment plans, and even to establish Manhattan or Apollo-type policy preeminince.     

Adolescent fears: Some Caribbean findings

A total of 657 adolescents (12–15 years) in Barbados provided responses to the question, “Is there anything you are really scared or afraid of?” Most frequently named fears were of three main types: fear of injury or death of self or loved ones, sexual concerns, and fears associated with school failure. However, certain other fears usually reported as relatively infrequent among adolescents in industrialized countries, such as fear of the dark, fear of walking lonely roads, and fear of animals, were also prominent, and reflect local geographical and cultural conditions. The influence of the media was also evident: many students were concerned about nuclear war, or held somewhat exaggerated fear of certain threats to personal safety (for example, being killed) given actual local incidence levels. From a guidance and counseling perspective, the data particularly highlight the need for improved sex and family life education.
