Recommendations of best practice to conduct identifications in settings with large numbers of victims and technological limitations are provided, based on a sample of 116 cases in which positive presumptive identifications were generated using "traditional" techniques, and were later corroborated through DNA testing. Traditional techniques generally consist of combining witness testimony, personal effects and clothing, anthropological and dental data to corroborate or to exclude the identity of an individual. Experts participating in traditional identifications must develop emic categories to transform objective physical features into recognizable categories by the family, or to do very the opposite-to develop an ethic system by which the expert translates the cues given by a family member into objective categories that are usable in standard forensic and legal contexts. 相似文献

This paper aims to establish an initial determination of what the primary indicators of the ease of access to small arms and
light weapons are. Guns are so abundant and ubiquitous in most parts of the world that the right question to ask is not how
many guns are out there but what are the conditions, or lack thereof, that promote the ease of access. This paper also aims
to offer researchers with initial tools for coding indicators for the ease of access in future investigations on this important
topic. At the outset, I introduce three sets of indicators: legal, ‘black market feeder indicators’, and socialeconomic indicators.

There are specific challenges related to forensic dental radiology and difficulties in aligning X‐ray equipment to teeth of interest. Researchers used 3D printing to create a new device, the combined holding and aiming device (CHAD), to address the positioning limitations of current dental X‐ray devices. Participants (N = 24) used the CHAD, soft dental wax, and a modified external aiming device (MEAD) to determine device preference, radiographer's efficiency, and technique errors. Each participant exposed six X‐rays per device for a total of 432 X‐rays scored. A significant difference was found at the 0.05 level between the three devices (p = 0.0015), with the MEAD having the least amount of total errors and soft dental wax taking the least amount of time. Total errors were highest when participants used soft dental wax—both the MEAD and the CHAD performed best overall. Further research in forensic dental radiology and use of holding devices is needed. 相似文献

This study presents the results of the analysis of at least 298 predominantly male individuals, between 15 and 75 years, who were recovered from an open cast mine in Bosnia-Herzegovina. Particular attention is paid to identifying the mechanisms of injury and determination of the most probable cause of death based on the assessment of lethal or lethal-if-untreated injuries recorded in the skeleton. It was calculated that at least 38.9% (155/398) of individuals sustained gunshot wounds (GSWs) (plus one shrapnel wound) and may have died as consequence of these injuries. Among individuals who died from GSWs, there were 142 males (91.60%), eight females (5.1%) and five cases that were (3.2%) undetermined. One male individual sustained shrapnel injuries. This study presents an example of the multidisciplinary approach to the effective forensic investigation of violation against International Humanitarian Law, as well as an example of how it is possible to obtain meaningful results to assist the needs of the prosecution in these kind of cases despite the large number of cases and technological constraints. 相似文献

A rapid, accurate, precise, reproducible, economical, and environmentally gentle method using capillary electrophoresis (CE) is presented for the routine analysis of methamphetamine, amphetamine, MDA, MDMA, MDEA, and cocaine in seized drugs. The methodology uses a 32 cm by 50 microm capillary (length to detector 23.5 cm) with a commercially available buffer kit and diode array UV detection. Dynamic coating of the capillary surface is accomplished by flushing with base for 1 min, a proprietary polycation for 1 min, and then a proprietary polyanion for 2 min. This approach provides a relatively high and stable electroosmotic flow (EOF), even at low pHs. The background electrolyte (BGE) contains 75 mM phosphate buffer (pH 2.5) with the same polyanion as above. Using this methodology, amphetamine, methamphetamine, MDA, MDMA, MDEA, and an internal standard (n-butylamphetamine) are baseline resolved in less than 5 min. The run-to-run migration time %RSDs and peak area %RSDs are typically <0.3% and <2.1%, respectively. The day-to-day and capillary-to-capillary migration time %RSDs are <1.5% and <2.1%, respectively. The %RSDs of the relative migration times compared with the internal standard on a day-to-day and capillary-to-capillary basis are <0.2% and <0.06%, respectively. The linear dynamic range using peak areas range from 0.003 to 0.10 mg/mL. The correlation coefficients are >0.9998, with all calibration curves passing at or near the origin. Similar data are obtained for cocaine and its internal standard henyltoloxamine. None of the compounds usually encountered in illicit samples interfere with the target compound (e.g., methamphetamine and cocaine) or the internal standard. Quantitative results for synthetic mixtures and seized exhibits are in good agreement with actual values, and also with results obtained from other techniques. The relatively high EOF for the dynamically coated capillary system allows for the screening of basic, acidic, and neutral adulterants in drug seizures; identification is facilitated by the use of automated UV library searches. 相似文献

The study of the impact of the economic crisis on attitudes toward democracy tends to be focused on satisfaction with specific democratic institutions. This article expands upon previous research to explore how the current economic crisis can affect core support for democracy as a regime. Based on European Social Survey data for the Eurozone countries, the findings are twofold. It is shown, firstly, that perceptions of the state of the economy have an impact both on satisfaction with and support for democracy, and, secondly, that citizens’ support for democracy is greater in bailed-out countries. In countries that have experienced intervention, the more critical citizens and those less satisfied with the outputs of democracy are the stronger advocates of democracy. The article argues that this is connected with the tendency of critical citizens in bailed-out countries to blame external agents for the economic situation while increasing the saliency of democratic rules as a reaction to the imposition of unpopular measures. 相似文献
