Forensic Facial Reconstruction: Relationship Between the Alar Cartilage and Piriform Aperture 下载免费PDF全文

During forensic facial reconstruction, facial features may be predicted based on the parameters of the skull. This study evaluated the relationships between alar cartilage and piriform aperture and nose morphology and facial typology. Ninety‐six cone beam computed tomography images of Brazilian subjects (49 males and 47 females) were used in this study. OsiriX software was used to perform the following measurements: nasal width, distance between alar base insertion points, lower width of the piriform aperture, and upper width of the piriform aperture. Nasal width was associated with the lower width of the piriform aperture, sex, skeletal vertical pattern of the face, and age. The current study contributes to the improvement of forensic facial guides by identifying the relationships between the alar cartilages and characteristics of the biological profile of members of a population that has been little studied thus far. 相似文献

A Morphological and Morphometric Study of Bite Marks Caused by Mice (Mus Musculus) on Different Baits for Forensic Purposes 下载免费PDF全文
Víctor A. Toledo M.V. Gabriel M. Fonseca D.D.S. Ph.D. Paula A. González M.V. Luis Ibarra M.V. Francisco J. Torres T.M. Pedro L. Sáez Ph.D. 《Journal of forensic sciences》2017,62(2):462-467
In animal bites, the dental attributes can be fundamental in identifying the marks made by various species on different matrices. Although rodent bite marks have been studied in the context of postmortem interference, little research has used different baits to analyze these marks linking not only specific behavior patterns but also the possibility of structural damage. Twenty mice (Mus musculus) were exposed to different baits to study their bite marks in a controlled model. The known pattern of parallel and multiple grooves has been seen in all baits, but polyvinyl chloride and fiber‐optic cable were significantly different between each other and the other baits. Some baits showed patterns of anchorage of the upper incisors and space between the lower incisors when gnawing. This technical note represents a novel model of analysis where veterinarians and/or dentists may be asked to give an opinion on alleged animal bite marks. 相似文献

Oxelytrum discicolle is a carrion beetle commonly found in the Neotropical region, mainly associated with cadavers and carcasses. Information on behavior related to the likelihood of cadaver colonization is scarce. We performed two field experiments in peri‐urban forest in Brazil in order to strengthen our knowledge on O. discicolle behavior. In the first experiment, we assessed the preference for piglet carcasses at different stages of decomposition offered simultaneously in two seasons, dry and rainy, while in the second experiment we investigated the diel activity of adults. A total of 493 adults were collected in the experiments. A significantly higher abundance was detected in the rainy season. There was a marked preference for carcasses at advanced stages. Adults exhibited a typical nocturnal behavior, the number trapped at night was 17 times greater than those collected during the day. Oxelytrum discicolle is nocturnal species that prefers carcasses in advanced stage of decomposition. 相似文献

Forensic facial approximation is an auxiliary method for human identification and allows facial recognition. The midface, that includes the nose, is vital for the recognition of a familiar face. The purpose of this study was to set hard tissue parameters to estimate nasal width, to test the method to estimate nasal width of Brazilians, and to analyze the relationship between nasal profile and facial type. A total of 246 computed tomography scans (183 females and 63 males) of adults were analyzed in Horos. Bone tissue measurements and facial type classification were performed on the skull scan. Nasal profile morphology was accessed through the tool 3D surface rendering. There was a difference around 3 mm from real to predicted nose through the method to estimate nasal width in Brazilians. So, the method may be used in forensic practice. Straight nose was associated with long face type. 相似文献

Collective remittances are the money flows sent by hometown associations (HTAs) of migrants from the USA to their communities of origin. In Mexico, the 3?×?1 Program for Migrants matches by three the amounts that HTAs send back to their localities to invest in public projects. In previous research, we found that municipalities ruled by the party of the federal government were more likely to participate in the Program. The political bias in participation and fund allocation may stem from two possible mechanisms: HTAs?? decisions to invest in some municipalities but not in others may reflect migrants?? political preferences (a demand-driven bias). Alternatively, government officials may use the Program to finance their own political objectives (a supply-driven bias). To determine which of these two mechanisms is at work, we studied a 2?×?2 matrix of statistically selected cases of high-migration municipalities in the Mexican state of Guanajuato. We carried out over 60 semistructured interviews with state and municipal Program administrators, local politicians, and migrant leaders from these municipalities. Our qualitative study indicates that migrant leaders are clearly pragmatic and that the political bias found is driven by elected officials strategically using the Program. The bias in favor of political strongholds is reinforced by the Program??s requirements for cooperation among different levels of government. This study casts doubt about the effectiveness of public?Cprivate partnerships as valid formulas to reduce political manipulation. It also questions the ability of matching grant programs to reach the areas where public resources are most needed. 相似文献

The Peace Agreement signed recently between the Government and FMLN guerrillas in El Salvador marks the end of a decade of civil war. As both sides of the conflict and the international donor community begin to add up the financial costs of reconstruction, the human, social and psychological costs are carried mainly by the poor of El Salvador. Social organisations and NGOs who became strategists of survival now face the challenge of transforming their accumulated experience into alternative proposals for the building of a more just society and a prosperous nation. This article explores the practical complexities of transition from war to peace; and from emergency aid to sustainable development based on the participation of communities, social organisations, NGOs, and international agencies; and the challenges of building on their experience. 相似文献

This paper explores the possibility of revising the voting system in order to provide the citizen with the alternative of voting for none of the candidates on the ballot as opposed to selecting a specific candidate or not voting at all. We describe in general terms the nature and implications of such a proposal and leave the formal development of the model for a subsequent paper. In addition, preliminary evidence is presented as to the potential effect of this alternative on the electoral system. 相似文献
