This study investigated the value of antemortem (AM) and postmortem (PM) radiographs of the claviculae and C3-T4 vertebrae to identify skeletons of missing U.S. soldiers from past military operations. In total, 12 field-recovered skeletons and AM chest radiographs of 1460 individuals were used. For each skeleton, examiners analyzed an array of AM chest radiographs (up to 1000 individuals) and attempted to identify the correct PM/AM radiographic match. When examiners were able to compare all images within a single test, only true-positive identifications were made. When AM radiographs were presented one-at-a-time, in sequential order, and without examiners having knowledge of array size, erroneous identifications resulted but they were almost exclusively made by untrained examiners (accuracy = 35% vs. 90% for trained examiners). This study demonstrates the value of chest radiographs for the identification of disarticulated and even eroded skeletons, but only when methods are wielded by trained examiners. 相似文献

- George W. Bush won the 2004 US Presidential election despite the facts of one thousand people losing their life in the Iraq war, the highest rate of increase in unemployment in 70 years and a vitriolic propaganda campaign (Michael Moore, etc.) against him. This case study seeks to explain the success through the prism of marketing theory and conceptual structures, that is, that the Bush team had a superior communications strategy and, within those parameters, superior marketing elements. Thus we seek to surface and integrate a number of causal explanations for his victory that arose from a political marketing orientation, specifically the offer of a ‘coherent narrative’; the conduct of a ‘permanent campaign’; more effective negative advertising (especially by pro‐Bush 527 groups), targeting and packaging; the success of the late campaign ‘big tent’ ploy. None of this however seeks to exclude the more purely political explanations for his success (located in such phenomena as the mobilization of the ‘Christian Right’ and the continuity to the aura attached to the ‘911 President’); nor is the application of marketing thought to political contexts treated uncritically.
- A further aim is to introduce political marketing modes of analysis to a political science audience—not to present them as a new ‘correctness’, for they are certainly vulnerable to challenge, but rather to precipitate more of an intellectual exchange between these two disciplines.

This article contributes to the emerging literature on transparency by developing and empirically testing a theoretical framework that explains the determinants of local government Web site transparency. It aims to answer the following central question: What institutional factors determine the different dimensions of government transparency? The framework distinguishes three dimensions of transparency—decision making transparency, policy information transparency, and policy outcome transparency—and hypothesizes three explanations for each: organizational capacity, political influence, and group influence on government. Results indicate that each dimension of transparency is associated with different factors. Decision‐making transparency is associated with political influence; when left‐wing parties are strong in the local council, local government tends to be more transparent. Policy information transparency is associated with media attention and external group pressure, and policy outcome transparency is associated with both external group pressure and the organizational capacity. The authors discuss the implications for policy and administration. 相似文献

We investigated the feasibility of postmortem percutaneous needle biopsy (PNB) for obtaining pulmonary samples adequate for the study of pulmonary fat embolism (PFE). Samples of both lungs were obtained from 26 cadavers via two different methods: (i) PNB and (ii) the double-edged knife technique, the gold standard at our institute. After water storage and Sudan III staining, six forensic pathologists independently examined all samples for the presence and severity of PFE. The results were compared and analyzed in each case regarding the vitality of the PFE and its relationship to the cause of death. The results showed that PFE was almost identically diagnosed and graded on the samples obtained via both methods. The discrepancies between the two techniques did not affect the diagnoses of vitality or cause of death related to PFE. This study demonstrates the feasibility of the PNB sampling method for the diagnosis and interpretation of PFE in the postmortem setting. 相似文献

Anthropometric, mortality, and population data presented by Svedberg [1990] in this journal suggested a slight anti‐male bias in undernutrition in sub‐Saharan Africa. This article re‐analyses some of the same anthropometric, mortality, and population data and supplements them with more recent findings. In contrast to Svedberg's results, it finds evidence of a slight and rising anti‐female bias in sub‐Saharan Africa, which is particularly apparent in mortality and population indicators. 相似文献

Facial approximation was first proposed as a synonym for facial reconstruction in 1987 due to dissatisfaction with the connotations the latter label held. Since its debut, facial approximation's identity has morphed as anomalies in face prediction have accumulated. Now underpinned by differences in what problems are thought to count as legitimate, facial approximation can no longer be considered a synonym for, or subclass of, facial reconstruction. Instead, two competing paradigms of face prediction have emerged, namely: facial approximation and facial reconstruction. This paper shines a Kuhnian lens across the discipline of face prediction to comprehensively review these developments and outlines the distinguishing features between the two paradigms. 相似文献
