A comparison between direct and indirect methods available for human bite mark analysis

Comparison techniques used in bite mark analysis are many and varied, the choice of technique depending largely on personal preference. Until recently, no one technique has been shown to be better than the others, and very little research has been carried out to compare different methods. This study evaluates and compares the accuracy of direct comparisons between suspects' models and bite marks with indirect comparisons in the form of conventional traced overlays of suspects' models or a new method using photocopier-generated overlays. Artificial bite marks in pigskin were made using standardized sets of models and recorded as photographs and fingerprint powder lifts on tape. The bite mark photographs and fingerprint lifts were coded and randomized so that a blind comparison could be made with the models, traced overlays, and photocopier-generated overlays using a modified version of the American Board of Forensic Odontology Scoring (ABFO) System for Bite Marks. It was found that the photocopier-generated overlays were significantly more accurate at matching the correct bite mark to the correct models irrespective of whether the bite mark was recorded photographically or as a fingerprint lift. The photocopier-generated overlays were also found to be more sensitive at matching the correct bite marks to the correct models than the other two methods used. The modified ABFO scoring system was able to discriminate between a correct match and several incorrect matches by awarding a high score to the correct match.     

Drawings of the opposite sex: Continued use of the draw a person test and young state hospital patients

The Draw A Person test has continued to be one of the most frequently utilized psychological tests with children and adolescents. This is especially true for the child/adolescent populations in state hospitals. Because of the frequent criticism leveled against the DAP's validity, this study was undertaken in order to provide normative data for the DAP with this particular clinical population. Previous research has focused on the drawings of the same sex as the subjects; this study deals with the characteristics of the drawings of the opposite sex. The subjects were 84 male and 66 female psychiatric patients from the Adolescent Unit (AU) at Rusk State Hospital. As each patient was admitted to the AU, he was scheduled for psychological testing, with the DAP, the Revised Beta, and the MMPI being a part of this testing. The results of this study indicate that IQ ranking is the most significant factor affecting DAP test performance by male subjects. IQ ranking was not found to significantly influence the drawings by females. Neither MMPI test performance nor social background factors were shown to significantly affect DAP test performance. It is suggested that in order for the DAP to become a more objectively utilized personality technique, a scoring method should be developed that takes into account the overall quality of the drawing in conjunction with the individual details of each area of the figure drawn. More focus should also be given to the characteristics of the opposite-sex figure drawn by the subjects and its potential interpretation.Received his M.S. degree in psychology from North Texas State University in 1968.

Tax Increment Debt Finance: An Analysis of the Mainstreaming of a Fringe Sector

Despite the persistent efforts of federal tax policymakers to place binding constraints on the economic development bond market in the United States, it has grown since the Tax Reform Act of 1986 and is a well established segment of the municipal securities market. This article provides an analysis of the development bond market by describing tax increment debt finance (TIF) in the United States and conducting an empirical analysis of California TIF debt. Our analysis indicates that tax increment debt finance (TIF) is no longer an obscure infrequently used financing tool, but for local governments in many states is a commonly used means of raising capital for multiple purposes. Our empirical analysis highlights the unique project-specific features of tax increment finance that bond issuers must understand and manage to enhance the credit quality and minimize the financing costs of tax increment debt.     

Military Power and Food Security: A Cross-National Analysis of Less-Developed Countries, 1970–1990

Addressing the long-standing debate over the social impact of military power and recent discussions of military-induced famine, we conduct a panel analysis of aggregate food supply and child hunger rates in 75–79 less-developed countries (LDCs). Distinguishing between militarization , as the growth of military resources, and militarism , as the use of military force to handle political conflicts, we show that militarization is both beneficial and detrimental to food security, whereas militarism is consistently detrimental. Arms imports and associated increased military spending plus praetorianism and military repression reduce food security, whereas increased military participation and arms production boost food security. Increased food supply reduces child hunger and is largely confined to the more developed of the LDCs. These military power effects show net economic growth, which "trickles down" to improve food supply and reduce child hunger among the more developed LDCs, reflecting the growth of global economic inequality. Contrary to views that see militarization as a single unified process, use of armed force is not strongly rooted in either praetorianism or militarization.
