Why is Family Violence Lower Among Mexican Immigrants? The Protective Features of Mexican Culture

Although immigrants tend to be less involved in crime than the native-born, less is known about whether immigration is protective regarding family violence and, if so, why. This is especially problematic given that some cultural features of immigrants, such as machismo, may increase family violence. Using a random sample of adults in El Paso County, Texas, the present study finds that family violence is substantially lower among first generation Mexican immigrants compared to 1.5 generation immigrants, second generation Americans and third generation or higher Americans. Higher levels of acculturation to Mexico among first generation immigrants partially mediated, or explained, this finding. However, familism and machismo were not higher among first generation Mexican immigrants; and, while lower among first generation immigrants, acculturation to the US was not associated with higher levels of family violence. Implications of these findings are discussed.     

A Spanish population study of 17 Y-chromosome STR loci

Haplotype, allele frequencies and population data of 17 Y-chromosome STR loci DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460 (GATA A7.1), DYS461 (GATA A7.2), GATA A10, GATA C4 and GATA H4 were determined from a sample of 148 unrelated male individuals from Spain. A total of 144 haplotypes were identified by the 17 Y-STR markers, of which 141 were unique, two were found in two individuals and one was found in three individuals. The haplotype diversity (99.95%) and discrimination capacity (97.30%) were calculated. Comparisons were made with previously published haplotype data on other Iberian population samples and no significant differences were found.     

Choking death on a live fish (Dicologoglossa cuneata)

A choking death of a healthy fisherman, who put a type of live sole between his jaws to free up his hands so that he could collect more fish to put into his basket, is described. The fish squirmed into the larynx and upper trachea and the attempts to rescue the man by his colleagues who used pliers did not succeed, and the man died. Other published cases are reviewed, and risk factors and rescue possibilities discussed.     

The 2000-2001 GEP-ISFG Collaborative Exercise on mtDNA: assessing the cause of unsuccessful mtDNA PCR amplification of hair shaft samples

We report the results of Spanish and Portuguese working group (GEP) of International Society of Forensic Genetics (ISFG) Collaborative Exercise 2001-2002 on mitochondrial DNA (mtDNA) analysis. 64 laboratories from Spain, Portugal and several Latin-American countries participated in this quality control exercise. Five samples were sent to the participating laboratories, four blood stains (M1-M4) and a sample (M5) consisting of two hair shaft fragments. M4 was non-human (Felis catus) in origin; therefore, the capacity of the labs to identify the biological source of this sample was an integral part of the exercise. Some labs detected the non-human origin of M4 by carrying out immuno-diffussion techniques using antihuman serum, whereas others identified the specific animal origin by testing the sample against a set of animal antibodies or by means of the analysis of mtDNA regions (Cyt-b, 12S, and 16S genes). The results of the other three human blood stains (M1-M3) improved in relation to the last Collaborative Exercises but those related to hairs yielded a low rate of success which clearly contrasts with previous results. As a consequence of this, some labs performed additional analysis showing that the origin of this low efficiency was not the presence of inhibitors, but the low quantity of DNA present in these specific hair samples and the degradation.As a general conclusion the results emphasize the need of external proficiency testing as part of the accreditation procedure for the labs performing mtDNA analysis in forensic casework.     

Obstacles to preserving precaution and equity in global hazardous waste regulation: an analysis of contested knowledge in the Basel Convention

The Basel Convention is regaining attention for the potential entry into force of the heretofore stalled Ban Amendment. In this paper, we draw parallels between the current debate surrounding the Ban Amendment and contestations that occurred in the early years of the Basel Convention’s Technical Working Group (TWG) over defining ‘hazardousness.’ Like the present debate, TWG deliberations involved a contestation between two divergent discourses concerning how hazardous wastes should be regulated—as ideally managed versus actually managed in the global South. Scholars have shown how the TWG is a site for industry to press for a definition of hazardousness favorable to their economic interests. However, explorations of the specific processes by which this occurred—particularly, how a framework for defining hazardousness that privileges private technical expertise over concerns of precaution and equity was successfully institutionalized within the TWG—have yet to be completed. We show that it is important to reexamine this debate today in order to better understand current Basel Convention developments.

Feasibility of Contactless 3D Optical Measurement for the Analysis of Bone and Soft Tissue Lesions: New Technologies and Perspectives in Forensic Sciences

Abstract:  In forensic pathology and anthropology, a correct analysis of lesions on soft tissues and bones is of the utmost importance, in order to verify the cause and manner of death. Photographs, videos, and photogrammetry may be an optimal manner of immortalizing a lesion, both on cadavers and skeletal remains; however, none of these can supply a detailed three-dimensional (3D) modeling of the lesion. Up to now, only the use of casts has given us the possibility of studying deep lesions such as saw marks with an accurate and complete 3D reconstruction of bone structure. The present study aims at verifying the applicability of 3D optical contactless measurement for the accurate recording of soft tissue and bone lesions, in order to develop a unique and precise method of registering and analyzing lesions, both in forensic pathology and anthropology. Three cases were analyzed: the first, a car accident with blunt force skin injuries; the second, a murder with blunt force injury to the head applied with a metal rod; the third, a series of sharp force knife and saw lesions on bone. Results confirm that 3D optical digitizing technology is a crucial tool in the immortalization of wound morphology in the medico-legal context even on "difficult" substrates such as cut marks and saw marks on bone.     

Characterization of lesions in hanging deaths

Hanging is a common method of committing suicide and a routine task in medico-legal autopsies. The hanging mark is the most relevant external sign and its characteristics are well known, but, for unknown reasons, there are major differences in reports on internal findings. We retrospectively studied 228 consecutive cases of hanging deaths. A complete standard autopsy was performed for every case. We investigated the association between the characteristics of the hanging mark and the frequency of bone, cartilage, soft tissue, and vascular injuries with the mode of suspension. Most cases (75.3%) presented some kind of bone or cartilage fracture, but these were unrelated to any of the variables studied. Vascular lesions are clearly more infrequent: intimal injuries were found in the carotid artery (9.1%), the jugular vein (2.2%), and ruptures of the carotid adventitial layer (21.7%). These could be partially associated with the use of a hard fixed noose and body weight.
