Uncertainty in probabilistic genotyping of low template DNA: A case study comparing STRMix™ and TrueAllele™

Two probabilistic genotyping (PG) programs, STRMix™ and TrueAllele™, were used to assess the strength of the same item of DNA evidence in a federal criminal case, with strikingly different results. For STRMix, the reported likelihood ratio in favor of the non-contributor hypothesis was 24; for TrueAllele it ranged from 1.2 million to 16.7 million, depending on the reference population. This case report seeks to explain why the two programs produced different results and to consider what the difference tells us about the reliability and trustworthiness of these programs. It uses a locus-by-locus breakdown to trace the differing results to subtle differences in modeling parameters and methods, analytic thresholds, and mixture ratios, as well as TrueAllele's use of an ad hoc procedure for assigning LRs at some loci. These findings illustrate the extent to which PG analysis rests on a lattice of contestable assumptions, highlighting the importance of rigorous validation of PG programs using known-source test samples that closely replicate the characteristics of evidentiary samples. The article also points out misleading aspects of the way STRMix and TrueAllele results are routinely presented in reports and testimony and calls for clarification of forensic reporting standards to address those problems.     

Global Warming: Will There Be Exposure for Directors and Officers and Will It Be Covered?

This article will explore the potential legal liabilities of corporate officers and directors due to the effects of global warming on the business of their corporation, as well as the insurance coverage issues likely to arise under directors' and officers' (D&O) liability policies in light of those liabilities. The article focuses particularly on the pollution exclusion and the bodily injury and property damage exclusions, and also explores scenarios that may engender attempts by insurers to rescind the policy.     

A “concrete” identification in a dismemberment case

Homicide perpetrators can use concrete as a means to conceal their victims. When concrete encasement is encountered in the forensic field, albeit rarely, it is often coupled with postmortem dismemberment. This method of obscuring the evidence presents unique investigative obstacles, specifically related to identification. Various approaches to obtaining fingerprints from decedents encased in concrete have been suggested and implemented over the years. The presented case is that of an initially unidentified 44-year-old male, who was subject to postmortem dismemberment and concrete encasement. Meticulous excavation techniques facilitated preservation of evidence and an anatomical reconstruction of the body. These techniques enabled inspection of the incision sites of the dismembered remains during the postmortem examination. Identifiable jewelry and tattoos were noted at autopsy. Further, the resulting concrete molds could be utilized to obtain fingerprints. These prints were used to ultimately identify the decedent.     

State Fiscal Responses to Welfare Reform during Recessions: Lessons for the Future

The 1996 welfare reform transformed open-ended matching grants to states to fixed block grants. This article considers whether, given the new regime, states will be able and willing to meet the need for public assistance during recessions. The accumulation of large balances of unspent federal welfare funds helped states weather the first year or so of the current recession without having to cut programs for needy families. While new fiscal rules promoted positive reform during a period of economic prosperity, they may be leaving states and their most vulnerable citizens at serious risk as the economic and fiscal slowdown continues.     

Measuring Client Satisfaction and Engagement: The Role of a Mentor Parent Program in Family Drug Treatment Court

Parent engagement is an important intermediate outcome in Family Drug Treatment Court (FDTC) and child welfare services. This study explored the utility and reliability of a client satisfaction and engagement survey designed to measure interim outcomes of a Mentor Parent Program, operating in conjunction with a FDTC. Findings suggest the survey is a useful, parsimonious and reliable tool for measuring key dimensions of parent mentor services including client engagement; client‐centered support and empowerment; and help with systems navigation and accessing resources. The survey may be adapted for use in other FDTC or parent mentor contexts.     

Federal tax reform and the financing of state and local governments

Although the Reagan Administration tax reform proposals would reduce federal income tax liabilities for most taxpayers, federal tax reform would also create strong pressures on state and local governments to cut taxes and public services. These pressures would arise primarily because itemizers would no longer be able to deduct state and local taxes in determining their federal income tax liabilities. In New York City and Boston, it is likely that the Administration's tax reform would induce cuts in spending that range from 2.5 to 7.5 percent. While the elimination of state and local tax deductibility may promote allocative efficiency in the provision of local public goods, the cost would be a decline in the degree of redistribution through the state and local public sector, and a reduction in local public services for the poor.     

The Role of the Broker When Environmental Claims Occur

While environmental incidents tend to occur infrequently, they are often serious enough to disrupt the operations of the entities that experience releases of hazardous materials. The consequences of such events may include third-party claims for bodily injury and property damage, orders to clean up contamination, and regulatory actions against responsible parties. Fortunately, environmental insurance is available to provide protection against the financial consequences of a wide variety of pollution events. This article looks at the role of the broker in assisting clients to identify, analyze, and insure against environmental liability. With properly drafted policies and active participation in the claims management process, the broker can play a significant role in assuring that an environmental insurance policy responds as anticipated when an unexpected incident threatens a client's operations.
