SYMPOSIUM ON DUAL CONTAINMENT: U.S. POLICY TOWARD IRAN AND IRAQ

The following is an edited version of a symposium sponsored by the Middle East Policy Council on February 24, 1994, in the Russell Senate Office Building in Washington, D.C. George McGovern, president of the Council, moderated the panel; Thomas R. Mattair, the Councis resident policy analyst, was the organizer and discussant.     

Inter-observer error for area of origin analysis using FARO Zone 3D

In a bloodletting incident, the area of origin (AO) of an impact bloodstain pattern is crucial when establishing the sequence of events. The use of laser scanners and other three-dimensional (3D) technologies to document and analyse bloodstains have been the subject of previous papers, especially where AO analysis is concerned. FARO Zone 3D (FZ3D) is a relatively new software programme that can be used for bloodstain AO analysis. FZ3D requires a greater understanding of inter-observer errors associated with AO. This study looked at the inter-observer variation between 21 examiners when repeatedly calculating the AO six times for a single impact pattern on a plain white wall. An impact rig which consisted of a spring tension arm was positioned and fixed 45 cm from the X wall (right wall), and 45 cm from the Y wall (left wall). This experimental design resembles an impact blow for a bloodletting event. The AO was unknown to all examiners, making it a blind study. The collected results were documented in a Microsoft Excel datasheet and later analysed. From previous literature, a 30 cm acceptable allowance was utilised for AO analysis; however, there is currently no accepted standard error for this type of analysis. The overall total 3D mean error for all examiners was 5.62 cm. The maximum error for any one impact analysis was 24.27 cm. The variation of the data, which was collected by all examiners, was documented as X = 1.14 cm, Y = 1.24 cm, Z = 1.68 cm, and the total 3D error = 2.28 cm. The total 3D error for any one examiner and the variance between examiners did not exceed the 30 cm acceptable allowance utilised in previous literature.

The use of DNA stabilizing solution to enable room temperature storage and transportation of buccal and trace sample swabs

It is proposed that a DNA stabilizing solution (DNA Genotek Inc.) designed to preserve DNA in saliva samples at room temperature can be extrapolated to the storage of swab heads. The aim of this study was to evaluate the effectiveness of the solution for the preservation of reference swabs (buccal) and trace samples (facial swabs). To this end, the solution was used during a twin-site DNA transfer project assessing background levels of carer DNA present in children. Tubes containing 400 μl of solution were used to store and transport swab heads. At the laboratory, samples were extracted using the QIAamp DNA Mini Kit (Qiagen), quantified using the Quantifiler Duo Kit and profiled using the AmpF?STR^® SGM Plus^® PCR Amplification Kit (both Applied Biosystems). Twenty-eight PCR cycles were applied to all samples. Thirty-four cycles or a longer electrophoresis injection time was applied to trace samples where necessary. All Reference swabs produced high quantities of DNA and full DNA profiles after 28 cycles. Profile morphology indicated good quality DNA with no degradation. Of the trace samples, sufficient profiles were achieved to study the transfer of carer DNA making the solution fit for continued use in this project. DNA stabilizing solution enables the storage and transportation of swabs without freezing. This is convenient, reduces transportation costs and enables instant analysis of samples upon arrival at the laboratory. This is a useful alternative for a multi-site research project as well as a reliable storage tool for use in remote areas.     

Assessing the nature of nanotechnology: can we uncover an emerging general purpose technology?

Attention has increasingly shifted towards the long-run perspective on technological innovation, which suggests that progress comes in waves, each one originating with a major breakthrough or general purpose technology (GPT). This paper seeks to assess whether nanotechnology is likely to be (or become) a GPT, a characteristic that other researchers have sometimes assumed though not necessarily documented. Based on a survey of existing literature, this paper will explore the extent to which nanotechnology addresses three primary characteristics of a GPT: pervasiveness, innovation spawning, and scope for improvement. The paper draws on patent and patent citation databases to highlight the types of quantitative and qualitative information that would be necessary, and in some instances is still lacking, to characterize fully the nature of nanotechnology.

Motivation and Intervention in the Northern Ireland Peace Process: An Interview with President Bill Clinton

The role of former U.S. President William Jefferson Clinton in the Northern Ireland peace process has been acknowledged as an example of political risk‐taking and leadership driven by political interests and strategic post–Cold War aims. The tendency to examine Clinton's role from the perspective of international and global policy objectives, however, has obscured consideration of his motivational role in the Northern Ireland peace process and of how he moved between encouragement and intervention to help the political parties reach a settlement. This article, which is drawn from an extended interview conducted with Clinton in 2017, seeks to paint a more comprehensive picture of Clinton's participation in the peace process, showing how his combination of motivational and interventional skills enabled him to help convince others of the need to take risks for peace and gave him greater influence and leverage over the peace process as a result.
