THE ANALYSIS OF DESIGN OR THE DESIGN OF ANALYSIS?

The policy sciences have advanced in the past by introspection, and there appears to be a need for a return to such self-conscious examination of the field of inquiry. A design orientation offers a useful framework for such an examination. It requires reconsideration of some of the fundamental premises of policy inquiry. This article explores what impact design might have on the conventional process framework and then proceeds to discuss the development of a design perspective.     

Coming to Terms with Intramural Differences Over Policy Frameworks: How Policy Researchers Accommodate Rival Claims Among their Peers

Although we readily scrutinize conflicts among political stakeholders, similar attention is seldom paid to how we deal with contestable understandings within our own field of inquiry. Debates over competing scholarly perspectives and contested models are rarely subject to any systematic postmortem or attempts to account for differential survival. Given the indeterminacy of many of our conceptual schemes, empirical data seldom carry the day to a resolution all can accept. Accordingly, there are eventually many different versions of any given dispute, each offering a different path to resolution or equanimity. Disputants retire and conflicts fade, providing a demographic resolution of sorts, but not a scientific or a conceptual one. The work presented here claims that there is much to be gained from systematic scrutiny of our conceptual disputes, especially as a means to access the different perspectives we assume to handle them. We argue that there is an internal logic to the different perspectives on any given dispute. It is not the dispute per se that draws our interest; but rather, how any given dispute generates multiple interpretations and reconstructed versions. We propose and illustrate an approach to analyzing disputes that makes their internal logic more transparent and attends to the pathways that emerge for resolution. We will find, in the process, that there are some reliable routes to conciliation and some fault lines that remain unstable.     

Three-dimensional cranio-facial reconstruction in forensic identification: latest progress and new tendencies in the 21st century

Three-dimensional (3D) cranio-facial reconstruction can be useful in the identification of an unknown body. The progress in computer science and the improvement of medical imaging technologies during recent years had significant repercussions on this domain. New facial soft tissue depth data for children and adults have been obtained using ultrasound, CT-scans and radiographies. New guidelines for facial feature properties such as nose projection, eye protrusion or mouth width, have been suggested, but also older theories and "rules of thumbs" have been critically evaluated based on digital technology. New fast, flexible and objective 3D reconstruction computer programs are in full development. The research on craniofacial reconstruction since the beginning of the 21st century is presented, highlighting computer-aided 3D facial reconstruction. Employing the newer technologies and permanently evaluating and (re)questioning the obtained results will hopefully lead to more accurate reconstructions.     

Ear piercing affects earprints: the role of ear piercing in human identification

Previous research conducted into the use of the human ear in the field of forensic identification has focused upon the use of grids and manual methods to measure and catalogue the different anatomical features of the ear. To date, few have considered the importance of the presence of ear piercings and their possible role in human identification. This study aims to highlight the common distribution of piercings of both ears in both genders and to explore the effect of piercings on earprints. The presence of a piercing may, in part, help to explain why partial and not whole earprints are sometimes recovered from a scene of crime (suggesting that the offender's ears may be pierced). The presence of piercings through the tragus and the superior part of the helix are shown to be infrequent and thus may be used to assist the identification of a body, due to its relative rarity with respect to piercings found in other areas of the ear.     

Semi-automated ultrasound facial soft tissue depth registration: method and validation

A mobile and fast, semi-automatic ultrasound (US) system was developed for facial soft tissue depth registration. The system consists of an A-Scan ultrasound device connected to a portable PC with interfacing and controlling software. For 52 cephalometric landmarks, the system was tested for repeatability and accuracy by evaluating intra-observer agreement and comparing ultrasound and CT-scan results on 12 subjects planned for craniofacial surgery, respectively. A paired t-test evaluating repeatability of the ultrasound measurements showed 5.7% (n = 3) of the landmarks being significantly different (p < 0.01). US and CT-scan results showed significant differences (p < 0.01) using a Wilcoxon signed rank test analysis for 11.5% (n = 6) of the landmarks. This is attributed to a difference in the volunteer's head position between lying (CT) and sitting (US). Based on these tests, we conclude that the proposed registration system and measurement protocol allows relatively fast (52 landmarks/20 min), non-invasive, repeatable and accurate acquisition of facial soft tissue depth measurements.
