Careful Inspection (careful + inspection)
Selected AbstractsAn Insight into Forensic Document Examiner Expertise for Discriminating Between Forged and Disguised SignaturesJOURNAL OF FORENSIC SCIENCES, Issue 5 2008Adrian G. Dyer Ph.D. Abstract:, It has previously been shown that forensic document examiners (FDEs) have expertise in providing opinions about whether questioned signatures are genuine or simulated. This study extends the exploration of FDE expertise by evaluating the performance of eight FDEs and 12 control subjects at identifying signatures as either forgeries or the disguised writing of a specimen provider. Subject eye movements and response times were recorded with a Tobii 1750 eye tracker during the signature evaluations. Using a penalty scoring system, FDEs performed significantly better than control subjects (t = 2.465, p = 0.024), with one FDE able to correctly call 13 of the 16 test stimuli (and three inconclusive calls). An analysis of eye movement search patterns by the subjects indicated that a very similar search strategy was employed by both groups, suggesting that visual inspection of signatures is mediated by a bottom up search strategy. However, FDEs spent greater than 50% longer to make a decision than the control group. The findings are suggestive that for some stimuli FDEs can discriminate between forgeries and disguises, and that this ability is due to a careful inspection and consideration of multiple features within a signature. [source] Transmission of an undiagnosed sarcoma to recipients of kidney and liver grafts procured in a non-heart beating donorLIVER TRANSPLANTATION, Issue 6 2005Olivier Detry Transmission of an undiagnosed cancer with solid organ transplantation is a rare but dreadful event. In this paper the authors report the transmission of an undiagnosed sarcoma to recipients of kidney and liver grafts procured in a Maastricht category 3 non-heart beating donor. To the authors' knowledge this case is the first report of such a transmission with a liver graft procured in a non-heart beating donor. The cancer transferal was diagnosed 1 year after transplantation in the recipients of the liver and of one kidney. The liver recipient died from multiple organ failure after a failed attempt of tumor resection. The kidney recipient underwent immunosuppression withdrawal and transplantectomy. Non-heart beating donors should not be particularly at risk for undiagnosed cancer transmission if the procurement is performed according to the same rules of careful inspection of the abdominal and thoracic organs. After diagnosis of donor cancer transmission, kidney recipients should have the graft removed, and immunosuppression should be interrupted. The management of liver graft recipients is very difficult in this setting, and long-term survival was very rarely reported. (Liver Transpl 2005;11:696,699.) [source] Investigation of the correlations between 19F and 1H NMR signals for various mono- and di-substituted octafluoro[2.2]paracyclophanesMAGNETIC RESONANCE IN CHEMISTRY, Issue 5 2009Alex J. Roche Abstract A selection of mono- and pseudo ortho di-substituted octafluoro[2.2]paracyclophane derivatives were analyzed using 19F- 1H HOESY, 1H COSY and 19F COSY techniques. This resulted in the unambiguous assignment of the 19F and 1H NMR resonances, and also revealed interesting solvent effects and noteworthy coupling patterns for various JHH, JHF, and JFF interactions, including observable through bond 7JFF and 8JFF couplings. For the four mono-substituted derivatives, the assignments were achieved through the combination of 19F- 1H HOESY, 1H COSY and 19F COSY techniques. The C2 symmetry of the six pseudo ortho di-substituted derivatives that were examined produced simplified spectra, and careful inspection of the characteristic 1H coupling patterns led to the assignment of 1H signals. Therefore only 19F- 1H HOESY experiments were required to complete the assignments for those molecules. Refinements and alternative strategies for previous protocols are presented for the molecules that were less responsive to nuclear Overhauser effect (nOe) experiments.

[source] Development of chromatic adaptation transforms and concept for their classificationCOLOR RESEARCH & APPLICATION, Issue 3 2006Yoshinobu NayataniArticle first published online: 7 APR 200 Abstract Three types of international recommendations are necessary on CATs (chromatic adaptation transforms). CAT-Type I and CAT-Type II are for general use on chromatic adaptation studies. The former is related to chromatic adaptation theory and the latter to performance on field trial data. In addition, CAT-Type III is necessary for a specific and practical purposes. The need for classifying to CAT-Type I and CAT-Type II is found from a careful inspection of the development process from Nayatani et al. transform to BFD transform, referring to the Ph. D. thesis by Lam (University of Bradford, 1985). The process clearly shows two types of flows on the development of various CATs. One is the flow for deepening the theory of chromatic adaptation (CAT-Type I), and the other is for giving good performance to existing field trial data and also ease of use (CAT-Type II). Additional CAT-Type III is, for example, CAT recommended in CIE TC 8-04 technical report. The CAT is only applicable to compare hardcopy and softcopy images for the specified observing conditions in the report. Still, a difficult problem, determination of corresponding colors, remains in the method of subjective estimation, which is useful and widely used for estimating chromatic adaptation effects experimentally. © 2006 Wiley Periodicals, Inc.
