Political participation of ethnic minorities in the 1980s

Currently political participation, especially voter registration and turnout, varies substantially with ethnicity. Blacks and non-Hispanic whites participate at roughly equal rates, while Latinos and Asian-Americans are substantially less active. This variation may be the direct product of cultural factors, or it may reflect differences in the distribution of various determinants of participation, most notably education, citizenship, and age. Using data collected in 1984 on samples of California's black, Latino, Asian-American, and non-Hispanic white populations, we conclude that such variables fully account for lower Latino participation rates. Even with these controls, however, Asian-Americans remain less likely to vote. Because ethnic group consciousness is one of the variables related to activity, we conclude that ethnicity does have an indirect effect on participation as a basis for mobilization. In addition, we establish that noncitizens engage in nonelectoral activities, and we project future political participation rates of Latinos and Asian-Americans under several scenarios.     

The Deceptive Simplicity of Teaching Negotiation: Reflections on Thirty Years of the Negotiation Workshop

What is required for effective teaching depends on the goal of the effort, and our criteria for success should be much more demanding than positive ratings from participants. If the goal is to improve participants' effectiveness as negotiators, we need a proven theory and associated skills. In the absence of robust confirming empirical data, which is still mostly lacking, we can take some confidence from qualitative evaluations. But whether or not we have a proven theory, the pedagogical task is complex and challenging, calling for a variety of sophisticated techniques deployed by a skilled instructor committed to joint learning. This article tells the story of some of the instructors' pedagogical learnings in thirty years of teaching the pioneering Negotiation Workshop at Harvard Law School, many of which now have empirical support. It also suggests some areas and tools for more experimentation in future advanced courses.     

Identifying Southwest Hispanics using nonmetric traits and the cultural profile

Due to the increasing number of Southwest Hispanics in the United States, as well as the overwhelming number of foreign nationals that die every year trying to enter the United States along the southern United States border with Mexico, new methods for classifying individuals have been established at the Pima County Office of the Medical Examiner in Tucson, Arizona (PCOME). For each of the past 5 years, the PCOME has investigated a record number of deaths associated with these border crossings. The overwhelming majority of the identified decedents are Mexican Nationals. However, approximately 25% of these undocumented border crossers have yet to be identified, making it clear that improved methods for human identification are greatly needed. The first goal of this paper is to delineate the suite of skeletal nonmetric traits utilized in assessing Southwest Hispanic ancestry at the PCOME. This suite of nonmetric traits has proven to be an effective component in establishing the "biological profile" of unknown individuals in these cases. The second goal of this paper is to introduce methods used at the PCOME to establish the "cultural profile" of individuals in these cases. The "cultural profile" is a set of identification criteria that include: the geographic context of recovery, personal effects, dental health, and cultural accoutrements. Establishing the "cultural profile" in these cases is essential in identifying individuals as foreign nationals who have died trying to cross the border.     

Identifying the dead: methods utilized by the Pima County (Arizona) office of the medical examiner for undocumented border crossers: 2001-2006

The Pima County (Arizona) Office of the Medical Examiner has seen a dramatic rise over the past 6 years in the number of deaths related to the illegal crossing of our international border with Mexico. This rise in deaths is undoubtedly related to an increase in the number of foreign nationals who cross into the various Arizona jurisdictions that utilize the Pima County Medical Examiner to investigate their unnatural deaths. Because of the utterly dangerous nature of trekking across the Sonoran Desert, especially in the summer months, many of these unfortunate migrants succumb to the effects of heat-related illness and perish along the journey. The combined effects of a dry, hot environment and the remoteness of some of the trekking corridors can quickly render a deceased person unidentifiable by visual means. Thus, our office is faced with not only an increase in the number of deaths requiring medico-legal investigation but also an increase in the number of decedents needing additional specialized examinations in an effort to effect identification. This paper attempts to outline the problems and the methods utilized by our office over the past 6 years in the identification process of undocumented border crossers. It is hoped that this paper, as well as the others presented at this symposium, will allow for the sharing of information amongst all medical investigators who assist in the identification of these migrants. The identification of these individuals takes on added importance when one considers the possible nationalities, and perhaps motivation for entering into the US, of those that remain unidentified.     

A survey of background levels of explosives and related compounds in the environment

In this paper, swabbings from various public areas in 28 different cities throughout the United States were collected. A wide variety of objects were tested, ranging from park benches and telephones to sign posts and mailboxes. Inorganic anions and cations common in low explosives were detected simultaneously using capillary zone electrophoresis. Organic high explosives including nitroaromatics, nitramines, and nitrate esters were detected using gas chromatography with a pulsed-discharge electron capture detector. Confirmation of selected results was performed by ion chromatography and negative ion chemical ionization GC/MS. In general the results provide two major conclusions: (i) with the exception of nitrate, most low explosive oxidizers are rare in the environment; (ii) no organic explosives or significant interferences to these explosives were detected.
