An evaluation of matching unknown writing inks with the United States International Ink Library

Utilizing a database of standards for forensic casework is a valuable resource. Undoubtedly, as more standards (and corresponding information about the specimens) are collected, there is a greater certainty of identification when a questioned and a known item cannot be distinguished after a series of analyses. The United States Secret Service and the Internal Revenue Service National Forensic Laboratory jointly maintain the largest known forensic collection of writing inks in the world, which is comprised of over 8500 ink standards collected worldwide, dating back to the 1920s. This study was conducted to evaluate the reliability of matching arbitrarily purchased pens with known inks from a database. One hundred pens were randomly obtained from a variety of sources and their respective ink compositions were compared with standards. Eighty-five of the inks were determined to be suitable for comparison utilizing optical examinations and thin-layer chromatography. Three of the inks did not match any of the specimens on record; one of these inks was similar to an ink from an identical brand of pen that was in the database, but had a modified formulation.     

Ocular findings in pediatric deaths under 2 years of age (1994-2004)

Abstract:  Our purpose is to highlight novel ocular findings of 102 forensic pediatric cases under 2 years of age who die suddenly. Forensic information, grossing, and microscopic eye protocol was followed. The most common diagnosis was Sudden Infant Death Syndrome (SIDS) (57/102). Novel cytoid bodies were present in the retina of 72/102 cases and they were located predominantly 90% (65/72) at the anterior part of the retina ( p  < 0.001). Of the SIDS cases, 85% (47/57) showed the presence of cytoid bodies, and among all diagnosis, SIDS was the most associated with cytoid bodies ( p  = 0.003). A second observation was extramedullary hematopoiesis (EMH) identified in 35/102 cases and 22 of the 57 SIDS cases. The most frequent EMH location was the choroids (29/35). This study is the first to demonstrate the presence of cytoid bodies and extramedullary hematopoiesis in the retinas of SIDS cases and children who die suddenly from other causes.     

Domestic Violence and Children’s Presence: A Population-based Study of Law Enforcement Surveillance of Domestic Violence

The purpose of the present study was twofold: (1) to test whether law enforcement officers could reliably use a standard protocol to collect data on domestic violence events (DVEs) across a large municipality, and (2) to use these data to examine prevalence and nature of the violence and children’s presence. Reliability checks indicated that data were collected reliably on over 5,000 substantiated DVEs. Findings showed that 48% of all assaults in the municipality were DVEs. Victims were predominantly females in their early thirties, and injuries were predominantly minor and resulted from body contact. Children were present in nearly 50% of the DVEs. They were disproportionately present in domestic violence households compared to all other households in the municipality. Domestic violence households with children were more likely to have mothers and fathers involved in the violence and were disproportionately minority households headed by single females in relatively poor neighborhoods.     

WMD terrorism and US intelligence collection

Many analysts argue that better intelligence collection is necessary to improve the United States’ ability to prevent, deter and defeat WMD terrorism, but few give any concrete analysis of exactly what various types of intelligence can contribute to better understanding the WMD terrorist threat. This study outlines the emerging WMD terrorist threat and discusses the respective contributions that technical, human and open source intelligence can make in assessing the various stages of a WMD terrorist act. According to this analysis, neither imagery nor traditional human collection is capable of providing the critical information needed by policy makers. Rather, information collected by case officers working under unofficial cover and by clandestine means offer the best chance of identifying groups interested in producing and using WMD.     

An Investigation of a Community-based Intervention for Socially Isolated Parents with a History of Child Maltreatment

A randomized field trial was conducted to test the effectiveness of a community-based intervention to enhance the prosocial interaction and psychological well-being of urban, Head Start parents with a history of child maltreatment. One-hundred and sixteen socially isolated parents participated. Forty of these parents had a history of child maltreatment. Maltreatment and non-maltreatment parents were assigned randomly to intervention and control conditions. The intervention involved 10 group-training sessions focusing on the relationship between stress and social support. Analyses revealed a significant main effect for the intervention group with intervention parents reporting lower levels of stress and higher levels of social activity than controls. No main effects for maltreatment status or maltreatment by intervention group interactions were found. Implications for community-based treatment were discussed.     

Analytical methods used for the discrimination of substances suspected to be bar soap: a preliminary study

The submission to forensic laboratories of unknown specimens suspected of being biological or chemical warfare agents has increased tremendously with the threat of terrorism. Oftentimes, a threatening correspondence that contains hoax materials is intended to make the recipient(s) believe they have been exposed to a toxin. In some cases, the perpetrator can use standard household products, such as detergents and soaps. Once these materials are received, they become forensic evidence and may be analyzed for identification and/or comparison with known seized material from a suspect(s). Two separate studies were conducted using different analytical protocols for bar soaps. In the first set, the forensic laboratory at the United States Secret Service conducted tests on 68 bars of soap using solid-phase microextraction and gas chromatography coupled with mass spectrometry. The 68 different soaps displayed unique total ion chromatogram profiles. Energy-dispersive X-ray analysis in conjunction with scanning electron microscopy was also used to characterize 46 of the 68 soaps as a preliminary study. In a second set of studies, as part of a homicide investigation, the laboratory at the California Department of Justice, Riverside, conducted examinations on 13 bars of soap by utilizing Fourier transform-infrared spectroscopy. The case study demonstrated that it is possible to distinguish some bar soaps using infrared analysis. Furthermore, the bar soaps could be distinguished from typical laundry detergents using this technique.     

No exit and the organization of voice in biotechnology and pharmaceuticals

Although leadership is typically seen as coming from the leaders of governments and major institutions, a strong case can be made that concerned citizens first articulate important issues and policies that official leaders then pick up and promote. In a market-based society dominated by large corporations, Hirschman's framework of exit, voice, and loyalty can be used to relate consumer and grassroots movements to markets, when participants believe there is no exit and loyalty (or acquiescence) is not an option. While "voice" is usually applied to the individual or consumer level, this article develops the concept of organized voice and illustrates how it has exhibited leadership in the controversial relations between the biotech and pharmaceutical industries and society as a whole. The essay concludes by urging more research on organized voice as a source of leadership and by outlining some important dimensions for researchers to consider.     

Reduction in Recidivism in a Juvenile Mental Health Court: A Pre‐ and Post‐Treatment Outcome Study

A review of an evaluation of the Court for the Individualized Treatment of Adolescents (a prototype Juvenile Mental Health Court in Santa Clara, California) is presented along with admission criteria. Participant demographics are described. McNemar Test and Paired T Test results show that study participants committed violent, aggressive, and property crimes in significantly lower numbers in the 23 months following court admission than in the 18 months preceding court admission, despite escalating patterns of antisocial behavior prior to court involvement. The importance of developing multidisciplinary models to address moderately severe offenders with serious mental illness is discussed.
