Who Controls the Content of Supreme Court Opinions?

Conventional arguments identify either the median justice or the opinion author as the most influential justices in shaping the content of Supreme Court opinions. We develop a model of judicial decision making that suggests that opinions are likely to reflect the views of the median justice in the majority coalition. This result derives from two features of judicial decision making that have received little attention in previous models. The first is that in deciding a case, justices must resolve a concrete dispute, and that they may have preferences over which party wins the specific case confronting them. The second is that justices who are dissatisfied with an opinion are free to write concurrences (and dissents). We demonstrate that both features undermine the bargaining power of the Court's median and shift influence towards the coalition median. An empirical analysis of concurrence behavior provides significant support for the model.     

Effect of Heat on the Fluorescence Properties of Tooth‐Colored Restorative Materials and Their Forensic Implications

During antemortem and postmortem comparison of dental records of carbonized victims, restorations may be part of such records. The objective of this study was to evaluate the effect of heat on the fluorescence behavior of contemporary tooth‐colored restorative materials and natural tooth structure when subjected to range of temperatures, using illumination with 405 nm wavelength light. A total of 132 human extracted teeth restored with tooth‐colored restorative materials were exposed to heat (200, 500, 900, 1200°C) in an oven for 30 min. Samples were imaged before and after heat treatment. All tooth‐colored restorative materials underwent changes in color and in fluorescence properties, at each of the temperatures used. Resin‐based restorative materials still fluoresced at 200°C, and at 500°C underwent major color changes due to volatilization of resin. Materials containing inorganic fluorophores still fluoresced at 900°C, while at 1200°C, none of the materials tested in this study showed any fluorescence.     

Social and economic impact of the commercialization of the Argus II artificial retina in the United States

Each year, the United States invests about $45 billion in research conducted by federal researchers within federal laboratories. These efforts generate extensive social benefits when results are transferred to the private sector. It is important that we effectively quantify the economic and societal impact of federal technology transfer activities to inform taxpayers and policymakers about the value of public investments in this form of research. The Argus II device, an artificial retina commercialized in the United States by Second Sight in 2013, provides a rich example of how private sector innovation can be enhanced by research collaborations with federal labs and academia. Over the 25-year journey from idea to product, Second Sight carried out research and development collaborations with six Department of Energy national laboratories and seven universities. The case of Argus II also offers valuable insight into (1) how private industry, academia, and government can work together to bring socially beneficial innovations to fruition and (2) the tradeoffs inherent in these public–private collaborations. In this paper, we use a Markov model to estimate the realized and potential future social benefits associated with Argus II. We provide an interactive tool that can be used to replicate our findings and modify assumptions using updated patient information as it becomes available. We also provide insight into the aspects of federal involvement surrounding the development of Argus II that contributed to its successful commercialization and discuss other spillover benefits from these public–private collaborations.     

Adapting the Police Authority Concept to a Centralised National Police Service: Appearance over Substance in the Republic of Ireland?

The Republic of Ireland has been convulsed by a series of police corruption scandals over the past fifteen years and they show no sign of abating. In 2015, in an attempt to stem the consequent drain in public confidence in the Garda, the government established a Policing Authority which it presented as ‘the most important single change in the governance of the Garda Síochána in its history’. This article critically examines whether the new Irish Policing Authority can be interpreted as a successful adaptation of the traditional police authority concept to a parliamentary democracy policed by a single, national body. In particular, it considers whether it is equipped to shield the Garda and policing from the influence of partisan political and institutional interests, while at the same time deliver transparent democratic scrutiny of the Garda and policing on behalf of all sections of the community.     

Constructing universal multiplex PCR systems for comparative genotyping

Analysis of length polymorphisms at STR loci in the human genome has become a standard approach for comparative genotyping in many areas including disease research and diagnostics, parentage assessment, investigations of human diversity, and forensic science. The simultaneous analysis of multiple STR loci through multiplex PCR and multicolor fluorescence detection offers sample conservation, high throughput, and automated genetic analysis. Careful design and optimization of tetranucleotide STR multiplexes has led to reliable, standardized systems that powerfully differentiate and distinguish individual human DNA profiles. The development of these multiplex systems involved a rigorous experimental strategy that included careful selection of PCR primer sequences (for yield, specificity, and multiplex compatability), along with optimization of PCR component concentrations, thermal cycling parameters, and fluorescence detection conditions. This developmental approach rendered well-characterized DNA typing systems that are high performing (sensitive, specific, and balanced), optimized to universal parameters (same reaction conditions), resilient to fluctuations in reaction conditions, and simple to implement and use routinely.     

CAPITAL MOBILITY, DOMESTIC POLITICS, and FRENCH MONETARY DIPLOMACY

This article evaluates the role of increased capital mobility, sectoral interests, and domestic institutions in bringing about policy change in French capital markets. Capital mobility played an indirect role by making it more costly for French governments to pursue inflationary economic policies. But it was domestic politics, not capital mobility, that led governments to achieve lower inflation by stabilizing the exchange rate. The key domestic political factor was institutional change to regulatory practices, while financial markets reduced bank lending to industry and internationalized French finance, breaking the strong ties and comon monetary diplomacy interests of bankers, industralists, and policymakers, and thereby weaken the political priority of promoting domestic growth and industrial competitiveness.     

Evidence in support of self-declaration as a sampling method for the formation of sub-population DNA databases

Well constructed sub-population databases are fundamental to the application of DNA-based forensic statistics. The size of such databases can affect the ability to examine adequately statistical or population genetic features, and the integrity of both the DNA profile and associated ethnicity information is also of importance. Use of short tandem repeat (STR) DNA profiling technology and the thoughtful construction of the governing legislation has seen large databases of DNA profiles collated for the four major sub-populations of New Zealand. Examination of the data illustrates the suitability of self-declaration as a means of categorizing samples on the basis of ethnicity.
