An accuracy assessment of forensic computerized facial reconstruction employing cone-beam computed tomography from live subjects

The utilization of 3D computerized systems has allowed more effective procedures for forensic facial reconstruction. Three 3D computerized facial reconstructions were produced using skull models from live adult Korean subjects to assess facial morphology prediction accuracy. The 3D skeletal and facial data were recorded from the subjects in an upright position using a cone-beam CT scanner. Shell-to-shell deviation maps were created using 3D surface comparison software, and the deviation errors between the reconstructed and target faces were measured. Results showed that 54%, 65%, and 77% of the three facial reconstruction surfaces had <2.5 mm of error when compared to the relevant target face. The average error for each reconstruction was -0.46 mm (SD = 2.81) for A, -0.31 mm (SD = 2.40) for B, and -0.49 mm (SD = 2.16) for C. The facial features of the reconstructions demonstrated good levels of accuracy compared to the target faces.     

Moving Images Through an Assemblage: Police, Visual Information, and Resistance

Through interviews with police and document analysis this article examines the movement of video surveillance images from source to police to the courts in order to assess and refine the surveillant assemblage concept. Using this concept, the case study reveals asymmetrical criminalization processes involving movement of this visual information. The study finds that most video surveillance images transferred to police come from private sources as a consequence of function creep and that their movement epitomizes creation of criminalized ‘data-doubles’. However, the article argues that this criminalizing movement through the police is revealed as less than a seamless process; it is dependent on human labour and encounters forms of resistance along the way that include increased police workload and technological limitations.     

Study of the reaction mechanism of 1,8-diazafluoren-9-one with the amino acid, L-alanine

This paper describes the study of the reaction between 1, 8-diazafluoren-9-one (DFO) with the amino acid L-alanine in methyl alcohol. Particular interest was paid to the possible role of the solvent which appears to react with the DFO to form a hemiketal that is the reactive species. A potential reaction pathway is proposed based on the current data collected. The reaction intermediates and products were identified by a variety of spectroscopic methods including mass spectrometry (MS), nuclear magnetic resonance (NMR) spectroscopy, and X-ray crystallography.     

The Transfer of Manufacturing Processes and Standards in U.S. Plants Operating in the U.K.

This paper finds that U.S. firms tend to utilize their manufacturing processes when operating in the U.K. but that they adopt the production standards of the host country. Three process technology variables are examined: MRP I (materials requirements planning), JIT (just in time), and TQM (total quality management). While significant differences are found between indigenous plants in each of the two countries, the adoption of these manufacturing technologies is similar for American firms operating in either country. In contrast, U.S. transplants are found to be enthusiastic adopters of ISO 9000, suggesting that host country effects are large when it comes to conforming to regional standards.     

Development and Properties of the Adolescent Friendship Attachment Scale

Two studies are reported presenting the development of the Adolescent Friendship Attachment Scale (AFAS), a 30 item self-report measure of adolescent close friendship conceptualized as an attachment relationship. Study One reports the results of exploratory and confirmatory factor analyses with a sample of 490 adolescents aged 13 to 19 years. A second-order factor model was supported with a single friendship attachment factor underlying three first order factors (Secure, Anxious/Ambivalent, Avoidant) similar to those reported in the broader attachment literature. The AFAS subscales were found to be appropriately reliable and demonstrated appropriate convergent and discriminant validity when compared to measures of attachment styles (the Relationship Questionnaire) and parental and peer group attachment (the Inventory of Parent and Peer Attachment). Study Two reports a successful replication of the factor structure with an independent sample of 787 adolescents. Further research evaluating the predictive utility of the AFAS is recommended. Ross.

His major research interests include adolescent relationships and adjustment, adjustment to major life transitions, and attachment across the lifespan.
