Determination of group specific component phenotypes in dried bloodstains by immunofixation on cellulose acetate.

Group specific phenotypes in dried bloodstains can be rapidly and reliably determined by immunofixation on cellulose acetate membranes. Up to 16 samples, can be analyzed simultaneously in less than 60 min, and the cellulose acetate electrophoretogram is retained as a permanent record.     

CRIME IN THE IVORY TOWER: THE LEVEL AND SOURCES OF STUDENT VICTIMIZATION*

Contrary to the image of college campuses as “ivory towers,” the victimization of college students recently has been portrayed as a serious problem deserving policy intervention. Based on interviews designed after the National Crime Victimization Survey, which were conducted with 3,472 randomly selected students across 12 institutions, we examined both the level and sources of students'victimization. More than one-third of the sample reported being victims during the 1993–94 academic year. Informed by the lifestyle-routine activities approach, the analysis revealed that the risk of property victimization was increased by proximity to crime, target attractiveness, exposure, and lack of guardianship. The main predictor of violent victimization was a lifestyle that included high levels of partying on campus at night and the recreational use of drugs.     

Identification of the murder weapon by intricate patterned injury measurements

Critical studies of an intricate blunt force injury pattern in a brutal homicide led to the identification of the murder weapon. A 50-year-old male was bludgeoned to death in his apartment during a robbery allegedly engineered by his daughter. Careful measurements and overlay construction of the wounds relative to the magazine catch, lanyard ring, magazine chamber, and butt of a 32-caliber Eistegui Hermanos fibar (Espa?a) automatic pistol led to the conclusion that either the alleged weapon or one identical to it caused the fatal injuries.     

DISENTANGLING THE EFFECTS OF GENDER AND INTIMACY ON VICTIM PRECIPITATION IN HOMICIDE*

Research indicates that incidents in which women kill their husbands are more likely to involve victim precipitation than incidents in which men kill their wives. Formulating a causal interpretation of this finding, however, is complicated because the observed pattern may reflect gender differences in violence rather than any special dynamics between husbands and wives. In this research, we introduce and illustrate a framework for disentangling the effects of intimacy and gender on violence. We examine the additive and multiplicative effects of the gender of the offender, the gender of the victim, and the relationship between the offender and victim on victim precipitation. For the most part, the pattern of victim precipitation in homicide reflects the fact that males tend to be more violent than females. However, we find some evidence of special dynamics for intimate partner homicides: Men who are killed by their partners tend to have more violent records than men who are killed in other circumstances.     

Human cannibalism: a case report

Human cannibal cases are relatively rare in modern civilized societies. We report a single case of familial cannibalism that occurred in Oklahoma in 1977. The investigation posed unique problems in pathology, psychiatry, criminalistics, and serology.     

The importance of “spillovers” in the policy mission of the advanced technology program

Government policies like the Advanced Technology Program (“ATP”) are intended, at least in part, to remedy the “market failure” inherent in the fact that a significant portion of the social benefits of new knowledge and technology are not captured by a firm that invests in R&D. ATP’s project selection, and its evaluation of the impact of its program, can be made more effective by explicitly incorporating the analysis of such “spillovers.” For project selection, this means identifying technological, organizational and economic factors that tend to oint to a large “spillover gap,” or deviation between the social and private rates of return to a proposed project. For program evaluation and assessment, it means adapting existing study methods that measure social returns to innovation in ways that explicitly capture spillover effects. This paper is based on a study that I performed for the ATP, Economic Analysis of Research Spillovers: Implications for the Advanced Technology Program, NIST GCR 97-708. I have benefited from comments and useful discussions with Zvi Griliches, Jeanne Powell, Rosalie Ruegg, and Richard Spivack. Some of the ideas in this paper grew out of previous joint research with James Adams. The views expressed herein are my own, however, and should not be attributed to any of these individuals or to the ATP.
