Rosario Barranco M.D. Fiorella Caputo M.D. Davide Bedocchi M.D. Francesca Maria Elena Frigiolini M.D. Lara Castelletti M.D. Giulio Fraternali Orcioni M.D. Francesco Ventura M.D. Ph.D. 《Journal of forensic sciences》2020,65(1):314-317
Intravascular lymphoma (IVL) is a rare subtype of extranodal lymphomas that is characterized by the selective growth of neoplastic cells within the lumen of small vessels. Authors document the case of an unexpected death caused by an undiagnosed intravascular large B-cell lymphoma with multi-organ involvement, which had initially manifested as an infection and then as an unclarified central nervous system pathology. Histological examination showed a diffuse intravascular large B-cell brain lymphoma with prominent cerebral involvement. The relevance of the case report reveals the importance of an autopsy of an extremely rare and threatening pathology that in most cases is diagnosed only postmortem. As a result, the role of the forensic pathologist becomes particularly important. When specifically performing an in-depth autopsy evaluation with a specific histologic analysis, it is possible to identify the intravascular lymphoma and declare a more accurate cause of death. 相似文献

Many studies in the literature have highlighted the utility of virtual 3D databanks as a substitute for real skeletal collections and the important application of radiological records in personal identification. However, none have investigated the accuracy of virtual material compared to skeletal remains in nonmetric variant analysis using 3D models. The present study investigates the accuracy of 20 computed tomography (CT) 3D reconstruction models compared to the real crania, focusing on the quality of the reproduction of the real crania and the possibility to detect 29 dental/cranial morphological variations in 3D images. An interobserver analysis was performed to evaluate trait identification, number, position, and shape. Results demonstrate a false bone loss in 3D models in some cranial regions, specifically the maxillary and occipital bones in 85% and 20% of the samples. Additional analyses revealed several difficulties in the detection of cranial nonmetric traits in 3D models, resulting in incorrect identification in circa 70% of the traits. In particular, pitfalls included the detection of erroneous position, error in presence/absence rates, in number, and in shape. The lowest percentages of correct evaluations were found in traits localized in the lateral side of the cranium and for the infraorbital suture, mastoid foramen, and crenulation. The present study highlights important pitfalls in CT scan when compared with the real crania for nonmetric analysis. This may have crucial consequences in cases where 3D databanks are used as a source of reference population data for nonmetric traits and pathologies and during bone-CT comparisons for identification purposes. 相似文献

The purpose of this article is twofold: first, to examine the differences between buyers' and sellers' use of negotiation tactics in face‐to‐face business‐to‐business (B2B) negotiations and second, to explore how negotiators' professed negotiation styles influence buyers' and sellers' use of tactics. The methodology is a multiple case study analysis of eighteen negotiators representing twelve companies in six real‐life buyer–seller negotiations in B2B settings analyzed using qualitative research methods, including both comparative analysis and frequency analysis. We found some difference between buyers' and sellers' use of negotiation tactics, which suggests this question deserves further empirical study. Buyers' and sellers' use of specific tactics differs according to which overall strategy the negotiators chose, and sellers generally use a greater number of negotiation tactics than buyers. The findings challenge previous findings that suggest that B2B negotiations are collaborative and that negotiators communicate in a collaborative manner. The findings also increase our understanding of buyers' and sellers' variable use of tactics in the course of everyday practice as well as the interplay between negotiation tactics and strategies. 相似文献

Do the illegal and legal rents of politicians affect municipal election outcomes? Empirical evidence
Bernardino Benito María-Dolores Guillamón Ana-María Ríos Francisco Bastida 《Local Government Studies》2019,45(4):546-568
This paper aims to analyse whether illegal (corruption) and legal rent extraction (high politicians’ wages) affect electoral outcomes at municipal level. We use an initial sample of 145 Spanish municipalities over 50,000 for two electoral periods: 2004–2007 (before the crisis) and 2008–2011 (during the crisis). Our findings show that neither illegal nor legal rent extraction impact on re-election in non-crisis times. However, we observe that citizens penalize legal rent extraction in the ballots during the crisis. Regarding the economic performance of the local governments, we find that its effect on re-election is important in non-crisis period. Nevertheless, in time of crisis, given that the economic situation is bad in general in the country, voters pay less attention to economic factors and focus on politicians’ behaviour. 相似文献

In recent years, Spanish local governments have come under increasing pressure to accommodate severe economic restrictions while maintaining their provision of local public services. We analyse overall cost efficiency in Spanish local governments during the period of the economic crisis (2008–2013), under four different non-parametric methodologies. Moreover, given how problematic it is to precisely define what municipalities do, we compare three different output models with various measures of quantity as well as quality. Results suggest that Spanish local government efficiency improved over the period 2008–2013 since budget expenditures (inputs) fell while local public services and facilities (outputs) were maintained. We also find evidence of the possible implications of service quality when measuring municipalities’ efficiency, and of structural differences in the average efficiency between municipalities located in different Spanish regions. Finally, our results confirm that the level and variation of efficiency scores are affected by the approach taken. 相似文献
