The Reliability of Pattern Classification in Bloodstain Pattern Analysis,Part 1: Bloodstain Patterns on Rigid Non‐absorbent Surfaces

This study was designed to produce the first baseline measure of reliability in bloodstain pattern classification. A panel of experienced bloodstain pattern analysts examined over 400 spatter patterns on three rigid non‐absorbent surfaces. The patterns varied in spatter type and extent. A case summary accompanied each pattern that either contained neutral information, information to suggest the correct pattern (i.e., was positively biasing), or information to suggest an incorrect pattern (i.e., was negatively biasing). Across the variables under examination, 13% of classifications were erroneous. Generally speaking, where the pattern was more difficult to recognize (e.g., limited staining extent or a patterned substrate), analysts became more conservative in their judgment, opting to be inconclusive. Incorrect classifications increased as a function of the negatively biasing contextual information. The implications of the findings for practice are discussed.     

Covering Legal Mobilization: A Bottom‐Up Analysis of Wards Cove v. Atonio

We develop a political history of Wards Cove v. Atonio (1989) to show how Robert Cover's concepts of jurisgenesis and jurispathy can enrich the legal mobilization framework for understanding law and social change. We illustrate the value of the hybrid theory by recovering the Wards Cove workers’ own understanding of the role of litigation in their struggle for workplace rights. The cannery worker plaintiffs exemplified Cover's dual logic by articulating aspirational narratives of social justice and by critically rebuking the Supreme Court's ruling as the “death throe” for progressive minority workers’ rights advocacy. The cannery workers’ story also highlights the importance of integrating legal mobilization scholars’ focus on extrajudicial political engagement into Cover's judge‐centered analysis. Our aim is to forge a theoretical bridge between Cover's provocative arguments about law and the analytical tradition of social science scholarship on the politics of legal mobilization.     

Wealth-Transfer Taxes in U.S. Fiscal Federalism: A Levy Still in Need of Reform

Wealth-transfer taxes are federal and state levies on the valueof estates, inheritances, and gifts. Because the federal governmentallows a limited tax credit, repeal of the federal tax has implicationsfor state governments. This article discusses the economic justificationof taxing wealth transfers and provides data on the importanceof the tax from 1977 to 1997. We measure the degree of variationin the use of the tax among the states and pinpoint those statesfor which death taxation is most important. Wealth-transfertaxation needs reform but, repeal of the federal tax is inappropriate.Instead, the state levies should be abandoned. We conclude byproposing to repeal the state taxes and reduce the federal taxby an amount equivalent to the value of the federal tax-credit.The resulting revenues, however, would not to be garnered bythe federal government but returned as revenue-sharing fundsto the resident state of the decedent.     

Uneven local implementation of federal policy after disaster: Policy conflict and goal ambiguity

As climate change continues to increase both the frequency and intensity of environmental hazards and disasters, the need for a cohesive national mitigation policy grows. As the environmental federalism scholarship indicates, the inherent tension in federal, state, and local policy implementation highlights that despite a national need, environmental quality is a local public good. To complicate matters, there is disagreement about the optimal level of decision-making regarding the adoption and implementation of environmental policy. This study addresses this gap by considering the role of policy ambiguity and conflict in policy implementation. The analysis relies on primary qualitative data collected from open-ended interviews with 22 local government officials in 12 municipalities following Hurricane Harvey. Through the lens of policy ambiguity and conflict, we find confirmatory support for the idea that policies with less ambiguous goals are more likely to be implemented. Furthermore, we find that policy conflict arises when local governments perceive there is little for the community to gain by implementing the federal program. Thus, the level of protection afforded to citizens varies greatly between communities and is influenced heavily by politics. This research supports the Ambiguity-Conflict Model of policy implementation, an oft-cited but rarely tested theoretical framework for assessing the intergovernmental politics of policy implementation. It also demonstrates the barriers to local implementation of federal environmental policy in a nested system of government.     

The Probabilistic Genotyping Software STRmix: Utility and Evidence for its Validity

Forensic DNA interpretation is transitioning from manual interpretation based usually on binary decision‐making toward computer‐based systems that model the probability of the profile given different explanations for it, termed probabilistic genotyping (PG). Decision‐making by laboratories to implement probability‐based interpretation should be based on scientific principles for validity and information that supports its utility, such as criteria to support admissibility. The principles behind STRmix? are outlined in this study and include standard mathematics and modeling of peak heights and variability in those heights. All PG methods generate a likelihood ratio (LR) and require the formulation of propositions. Principles underpinning formulations of propositions include the identification of reasonably assumed contributors. Substantial data have been produced that support precision, error rate, and reliability of PG, and in particular, STRmix?. A current issue is access to the code and quality processes used while coding. There are substantial data that describe the performance, strengths, and limitations of STRmix?, one of the available PG software.     

UK Abortion Law: Reform Proposals,Private Members’ Bills,Devolution and the Role of the Courts

UK abortion law remains unsettled, and subject to on‐going controversy and reform. This article offers a comprehensive critique of all reforms implemented or proposed since 2016. It examines reforms proposed in both Houses of Parliament and contextualises them within a public law analysis, showing both that the complex parliamentary processes relating to Private Members’ Bills have frustrated reform attempts, and that these attempts have been contradictory in their aims between the two Houses. Secondly, it examines the unique positions of Northern Ireland, Scotland and Wales to show the extent to which devolutionary settlements have influenced both reforms and executive involvement. Finally, it examines the potential impact of the courts on abortion law following Re Northern Ireland Human Rights Commission's Application for Judicial Review, showing that the Supreme Court's reframing of the debate in human rights terms is likely to affect abortion law, not only in Northern Ireland, but in the whole of the UK.
