The Social Security Administration's 10-percent sample file of OASDI beneficiaries.

This is another in a series of technical articles describing Social Security Administration sample files and statistical systems. The focus of this article is the 10-percent sample file that provides program and demographic information on Social Security beneficiaries under the Old-Age, Survivors, and Disability Insurance program. The article explains the contents and availability of the 10-percent sample and presents several statistical tabulations as examples of the wide variety of data that can be developed from the file.     

Assessment of Maceration Techniques Used to Remove Soft Tissue from Bone in Cut Mark Analysis

Maceration techniques employed in forensics must be effective without compromising the bone's integrity and morphology, and prevent destruction of evidence. Techniques must also be fast, safe, easily obtainable and inexpensive; not all techniques currently employed are appropriate for forensic use. To evaluate the most suitable approach, seven techniques including current and new methodologies were applied to fresh, fleshed porcine ribs exhibiting cut marks. A sample size of 30 specimens per technique was examined under scanning electron microscopy at the cut mark and the surrounding uncompromised regions; a scoring system of effectiveness was applied. The previously unpublished microwave method fared best for bone and cut mark preservation. Sodium hypochlorite destroyed cut marks, and was deemed unsuitable for forensic analysis. No single technique fulfilled all criteria; however, this study provides a benchmark for forensic anthropologists to select the most appropriate method for their situation, while maintaining the high standards required by forensic science.     

Understanding rural resistance: contemporary mobilization in the Brazilian countryside

Contradictions between impressive levels of economic growth and the persistence of poverty and inequality are perhaps nowhere more evident than in rural Brazil. While Brazil might appear to be an example of the potential harmony between large-scale, export-oriented agribusiness and small-scale family farming, high levels of rural resistance contradict this vision. In this introductory paper, we synthesize the literature on agrarian resistance in Brazil and situate recent struggles in Brazil within the Latin American context more broadly. We highlight seven key characteristics of contemporary Latin American resistance, which include: the growth of international networks, the changing structure of state–society collaboration, the deepening of territorial claims, the importance of autonomy, the development of alternative economies, continued opposition to dispossession, and struggles over the meaning of nature. We argue that by analyzing rural mobilization in Brazil, this collection offers a range of insights relevant to rural contention globally. Each contribution in this collection increases our understanding of alternative agricultural production, large-scale development projects, education, race and political parties in the contemporary agrarian context.
