The role of forensic anthropology in disaster victim identification (DVI):recent developments and future prospects

Forensic anthropological knowledge has been used in disaster victim identification (DVI) for over a century, but over the past decades, there have been a number of disaster events which have seen an increasing role for the forensic anthropologist. The experiences gained from some of the latest DVI operations have provided valuable lessons that have had an effect on the role and perceived value of the forensic anthropologist as part of the team managing the DVI process. This paper provides an overview of the ways in which forensic anthropologists may contribute to DVI with emphasis on how recent experiences and developments in forensic anthropology have augmented these contributions. Consequently, this paper reviews the value of forensic anthropological expertise at the disaster scene and in the mortuary, and discusses the way in which forensic anthropologists may use imaging in DVI efforts. Tissue-sampling strategies for DNA analysis, especially in the case of disasters with a large amount of fragmented remains, are also discussed. Additionally, consideration is given to the identification of survivors; the statistical basis of identification; the challenges related to some specific disaster scenarios; and education and training. Although forensic anthropologists can play a valuable role in different phases of a DVI operation, they never practice in isolation. The DVI process requires a multidisciplinary approach and, therefore, has a close collaboration with a range of forensic specialists

How do MNC R&D laboratory roles affect employee international assignments?

Research and development (R&D) employees are important human resources for multinational corporations (MNCs) as they are the driving force behind the advancement of innovative ideas and products. International assignments of these employees can be a unique way to upgrade their expertise; allowing them to effectively recombine their unique human resources to progress existing knowledge and advance new ones. This study aims to investigate the effect of the roles of R&D laboratories in which these employees work on the international assignments they undertake. We categorise R&D laboratory roles into those of the support laboratory, the locally integrated laboratory and the internationally interdependent laboratory. Based on the theory of resource recombinations, we hypothesise that R&D employees in support laboratories are not likely to assume international assignments, whereas those in locally integrated and internationally interdependent laboratories are likely to assume international assignments. The empirical evidence, which draws from research conducted on 559 professionals in 66 MNC subsidiaries based in Greece, provides support to our hypotheses. The resource recombinations theory that extends the resource based view can effectively illuminate the international assignment field. Also, research may provide more emphasis on the close work context of R&D scientists rather than analyse their demographic characteristics, the latter being the focus of scholarly practice hitherto

'Complex' but coping : experience of symptoms of tuberculosis and health care seeking behaviours--a qualitative interview study of urban risk groups, London, UK

There is scant published research into the health actions of 'hard-to-reach' groups with tuberculosis, who represent approximately 17% of the London TB caseload. This study aimed to analyse patients' knowledge of tuberculosis, their experiences of symptoms and their health care seeking behaviours. METHODS: Qualitative interviews were conducted with 17 participants, predominantly homeless and attending a major tuberculosis centre in London, UK. Most had complex medical and social needs including drug and alcohol use or immigration problems affecting entitlement to social welfare. Analytical frameworks aimed to reflect the role of broader social structures in shaping individual health actions. RESULTS: Although participants demonstrated some knowledge of tuberculosis their awareness of personal risk was low. Symptoms commonly associated with tuberculosis were either not recognised or were attributed to other causes for which participants would not ordinarily seek health care. Many accessed health care by chance and, for some, for health concerns other than tuberculosis. CONCLUSIONS: Health education, based on increasing awareness of symptoms, may play a limited role in tuberculosis care for populations with complex health and social needs. The findings support the intensification of outreach initiatives to identify groups at risk of tuberculosis and the development of structured care pathways which support people into prompt diagnosis and treatment.Peer reviewedFinal Published versio

Linearisierter Verstaerker fuer Satellitenanwendungen (LVS). Arbeitspaket 4000: Validierung von MMIC Hybridschaltungen Abschlussbericht

The WP 4000 was performed in cooperation with Bosch Telecom, DaimlerChrysler Aerospace in Ulm (DASA) and in Ottobrunn (DSS) and United Monolithic Semiconductors (UMS). The aim of the program was the space evaluation of the PH25 process for production of MMIC hybrid circuits as well as the development of preamplifier linearizer circuits in C and Ku band. The PH25 process was evaluated by UMS in the frame of the program with technical support by ESA. For this purpose, UMS manufactured test structures and performed life tests with a duration of up to 4000 h with different bias and temperature conditions. During the tests, on one hand, the wear-out mechanism could be identified. On the other hand it came out that the components achieve the life time required for space applications. DASA designed the circuits for the linearizer-preamplifier device, which were manufactured at UMS, with the goal to integrate the device into the traveling wave tube. The task of DSS in this program was the manufacture of diode linearizers, which were integrated into the amplifier modules. Bosch Telecom pursued the concept of integrating the preamplifier-linearizer circuit into the power supply of the traveling wave tube. Bosch also designed circuits which were manufactured at UMS.

GaN-based amplifiers for wideband applications

Different wideband amplifiers, hybrid designs at lower frequencies, and monolithically integrated circuits (MMIC) at higher frequencies were designed, fabricated, and measured. These amplifiers are all based on AlGaN/GaN HEMT technology. The future applications for these types of amplifiers are mainly electronic warfare (EW) applications. Novel communication jammers and especially active electronically scanned array EW systems have a high demand for wideband high power amplifiers. The second application also needs high robust low noise amplifiers for its receive path. Output power levels of 38 W for hybrid amplifiers at lower frequencies up to 6 GHz and 15 W for the MMIC power amplifiers at higher frequencies are measured. With these building blocks, novel EW system approaches can be investigated

X-band T/R-module front-end based on GaN MMICs

Amplifiers for the next generation of T/R modules in future active array antennas are realized as monolithically integrated circuits (MMIC) on the basis of novel AlGaN/GaN (is a chemical material description) high electron mobility transistor (HEMT) structures. Both low-noise and power amplifiers are designed for X-band frequencies. The MMICs are designed, simulated, and fabricated using a novel via-hole microstrip technology. Output power levels of 6.8 W (38 dBm) for the driver amplifier (DA) and 20 W (43 dBm) for the high-power amplifier (HPA) are measured. The measured noise figure of the low-noise amplifier (LNA) is in the range of 1.5 dB. A T/R-module front-end with mounted GaN MMICs is designed based on a multi-layer low-temperature cofired ceramic technology (LTCC)
