Environmental Dynamics of Dissolved Organic Matter and Dissolved Black Carbon in Fluvial Systems: Effects of Biogeochemistry and Land Use

Black carbon (BC) is an organic residue formed primarily from biomass burning (e.g., wildfires) and fossil fuel combustion. Until recently, it was understood that BC was highly recalcitrant and stabilized in soils over millennial scales. However, a fraction of the material can be solubilized and transported in fluvial systems as dissolved BC (DBC), which represents on average 10% of the global export of dissolved organic carbon (DOC) from rivers to coastal systems. The composition of DBC controls its reactivity, and it has been linked with a variety of in-stream processes that induce both carbon sequestration and evasion of CO₂ from aquatic systems, which suggest DBC may have a significant contribution within the global carbon cycle. The primary objectives for the thesis were to elucidate environmental factors that control the fate and transport of DBC in fluvial systems. Ultra-high resolution mass spectrometry was used to characterize DBC on a molecular scale whereas benzenepolycarboxylic acids were used to quantify and characterize BC in both dissolved and particulate phases (PBC). Sinks for polycondensed DBC were linked to a series of in-stream biogeochemical processes (e.g., photodegradation, metal interactions); whereas photooxidation of particulate charcoal led to production of DBC, suggesting photodissolution as a previously unrecognized source of DBC to fluvial systems. Coupling of DBC with PBC, however, was hydrologically constrained with sources varying over temporal scales and land use regimes. For DBC in particular, an enrichment of heteroatomic functionality was observed as a function of anthropogenic land use. Furthermore, land use coupled with stream order (a proxy for in-stream processing as defined by the River Continuum Concept) could explain significant spatial variability in organic matter (e.g., DOC) composition within an anthropogenically impacted system. With an increase in wildfire frequency projected with on-going climate change trends, parallel projections for increases in BC production are also expected. Furthermore, conversion of natural landscapes for urban and agricultural practices is also expected to continue in the coming decades. Thus, it is imperative to reach a comprehensive understanding of processes regulating the transport of DBC in fluvial systems with efforts to constrain future BC budgets and climate change models

Executive Orders: Promoting Democracy and Openness in New York State Government

This joint report outlines 11 executive actions Gov. Andrew Cuomo can take to open up New York State government, increase the accountability of state agencies and reduce barriers to voting. The orders are centered on the basic goal of empowering the citizenry with more and better information about what its government is doing, and how it is spending tax payer dollars

Court Review: The Journal of the American judges Association, Vol. 57, No. 4

Court Review, the quarterly journal of the American Judges Association, invites the submission of unsolicited, original articles, essays, and book reviews. Court Review seeks to provide practical, useful information to the working judges of the United States and Canada. In each issue, we hope to provide information that will be of use to judges in their everyday work, whether in highlighting new procedures or methods of trial, court, or case management, providing substantive information regarding an area of law likely to be encountered by many judges, or by providing background information (such as psychology or other social science research) that can be used by judges in their work. Guidelines for the submission of manuscripts for Court Review are set forth on page 222 of this issue. Court Review reserves the right to edit, condense, or reject material submitted for publication

The Supreme Court and the Transformation of Juvenile Sentencing

In the past decade, the Supreme Court has transformed the constitutional landscape of juvenile crime regulation. In three strongly worded opinions, the Court held that imposing harsh criminal sentences on juvenile offenders violates the Eighth Amendment prohibition against cruel and unusual punishment. In combination, these cases create a special status for juveniles under Eighth Amendment doctrine as a category of offenders whose culpability is mitigated by their youth and immaturity, even for the most serious offenses. The Court also emphasized that juveniles are more likely to reform than adult offenders, and that most should be given a meaningful opportunity to demonstrate that they have done so. In short, because of young offenders’ developmental immaturity, harsh sentences that may be suitable for adult criminals are seldom appropriate for juveniles. These opinions announce a powerful constitutional principle – that “children are different” for purposes of criminal punishment. In articulating this principle, the Supreme Court has also provided general guidance to courts sentencing juveniles and to lawmakers charged with implementing the rulings. At the same time, the Court did not directly address the specifics of implementation and it left many questions unanswered about the implications of the opinions for juvenile sentencing regulation. In the years since Roper, Graham, and Miller, courts and legislatures have struggled to interpret the opinions and to create procedures and policies that are compatible with constitutional principles and doctrine. This report addresses the key issues facing courts and legislatures under this new constitutional regime, and provides guidance based on the Supreme Court’s Eighth Amendment analysis and on the principles the Court has articulated. Part I begins with the constitutional sentencing framework, grounded in the opinions and embodying the key elements of the Court’s analysis. It then explains the underlying developmental knowledge that supports the constitutional framework and the “children are different” principle. Part II Part II examines how courts and legislatures have responded to the Eighth Amendment opinions, through reforms of state laws regulating juvenile life without parole (JLWOP). While some state lawmakers appear to ignore or subvert the Supreme Court’s holdings, others have responded in ways that clearly embody the principles underlying Miller and Graham. In Montgomery v. Louisiana, the Court held that Miller applies retroactively because it established a substantive rule of constitutional law. Part III translates Miller’s directive that specific factors be considered in making individualized sentencing decisions. The report\u27s aim is to guide courts and clinicians in structuring sentencing hearings that incorporate sound developmental research and other evidence supporting or negating mitigation, without going beyond the limits of science. Part IV explores the broader implications of the Supreme Court’s developmental framework for juvenile sentencing and parole, implications that have already sparked law reforms beyond the relatively narrow holdings of Graham and Miller. Finally, the paper ends on a cautionary note, pointing to evidence that constitutionally sound, developmentally-based policies may be vulnerable to political and other pressures. Aside from mandates in the holdings themselves, reforms can be dismantled or discounted if conditions change. Measures to sustain the current trend in law reform are discussed
