Wrongful convictions are an increasing salient feature of criminal justice discourse in the United States. Many states have adopted reforms to mitigate the likelihood of wrongful convictions, discover errors, and provide redress in the wake of exonerations, yet we know little about why some are seemingly more committed to reducing such errors than others. We argue that public opinion is consequential for policy reform, but its effects are contingent on the electoral vulnerability of state lawmakers. We also suggest that advocacy organizations play a critical role in policy adoption. Incorporating data from all 50 states from 1989 to 2018, we investigate the adoption of five types of wrongful conviction reforms: (1) changes to eyewitness identification practices, (2) mandatory recording of interrogations, (3) the preservation of biological evidence, (4) access to postconviction DNA testing, and (5) exoneree compensation. Our results highlight a more nuanced view of how public opinion shapes policy.

OBJECTIVES/GOALS: There is no objective, biologic tool to detect concussion or guide clinical management. We previously showed that saliva microRNA (miRNA) levels differ in children with concussion and may predict symptom duration. The purpose of this study was to validate the utility of saliva miRNA and define longitudinal trends during the recovery period. METHODS/STUDY POPULATION: We collected concussion symptom burden (SCAT-5), cognitive performance (DANA), balance measures (ClearEdge), and saliva from 150 children (7-21 years) with concussion over 5 time-points: 0-2, 3-6, 7-14, 15-29, and 30-60 days post-injury. Saliva miRNA levels within the 443 concussion samples were quantified with RNA sequencing and compared to 218 samples from age- and sex-matched controls (healthy and post-exercise participants). Non-parametric ANOVA assessed RNA levels across time-points, and between concussions/controls. Machine learning was used to build logistic regression algorithms differentiating concussions/controls, and symptomatic/recovered concussion participants. Relationships between miRNAs and concussion phenotypes were explored with Spearman’s Rank correlations. RESULTS/ANTICIPATED RESULTS: Fifteen miRNAs differed across control and concussion participants (FDR < 0.05). Within concussion participants, all 15 miRNAs trended back toward control levels by 30-60 days post injury. A regression algorithm employing 6 of the 15 miRNAs differentiated control and concussion participants with an area under the curve (AUC) of 0.78 in a training set (n = 244) and 0.84 in a naïve test set (n = 24). Similarly, 6 miRNAs were able to differentiate symptomatic (SCAT-5 symptom score > 7) and asymptomatic concussion participants with an AUC of 0.73 in a training set (n = 219) and 0.76 in a naïve test set (n = 44). Furthermore, 5 miRNAs showed significant (R > 0.3; FDR < 0.05) associations with subjective and/or objective measures of concussion-related symptoms. DISCUSSION/SIGNIFICANCE OF IMPACT: Saliva miRNAs levels are altered in children with concussion, and display predictable longitudinal trends following injury. Saliva miRNA measurement represents a non-invasive, objective tool that could be rapidly assessed to provide biologic evidence for clinicians managing pediatric concussion.

This article combines new marine fish faunal data from medieval and early modern Icelandic archaeological sites with previously published data that focused primarily on the Settlement and Commonwealth periods. This synthesis places these new data into the larger scale of Icelandic history and marine conditions (sea-surface temperature and sea ice) to identify patterns and trends across the last 1000 years of the relationship between humans and Icelandic cod populations. We find no direct correlation between zooarchaeological patterns and sea ice or storminess in the medieval period and a possible correlation in the early modern period. We argue that this suggests a nuanced relationship between changing climates and fishing patterns in Icelandic history. While changes in sea temperature and periods of increased storminess might have made fishing productivity more variable and at times more dangerous, it is only in the early modern period that we see change in the marine zooarchaeological record that might indicate a correlation. Instead, we contend that the impacts of the changing climate relative to marine resources were mediated by social, political, economic, and even technological variables.

This article reviews the literature regarding the impact of cosmetic surgery on health-related quality of life (QOL). Studies were identified through PubMed/Medline and PsycINFO searches from January 1960 to December 2011. Twenty-eight studies were included in this review, according to specific selection criteria.
The procedures and tools employed in cosmetic surgery research studies were remarkably diverse, thus yielding difficulties with data analysis. However, data indicate that individuals undergoing cosmetic surgery began with lower values on aspects of QOL than control subjects, and experienced significant QOL improvement post-procedurally, an effect that appeared to plateau with time.
Despite the complexity of measuring QOL in cosmetic surgery patients, most studies showed an improvement in QOL after cosmetic surgery procedures. However, this finding was clouded by measurement precision as well as heterogeneity of procedures and study populations. Future research needs to focus on refining measurement techniques, including developing cosmetic surgery–specific QOL measures.

The purpose of this article is to set the context for this special issue of Disaster Medicine and Public Health Preparedness on the allocation of scarce resources in an improvised nuclear device incident. A nuclear detonation occurs when a sufficient amount of fissile material is brought suddenly together to reach critical mass and cause an explosion. Although the chance of a nuclear detonation is thought to be small, the consequences are potentially catastrophic, so planning for an effective medical response is necessary, albeit complex. A substantial nuclear detonation will result in physical effects and a great number of casualties that will require an organized medical response to save lives. With this type of incident, the demand for resources to treat casualties will far exceed what is available. To meet the goal of providing medical care (including symptomatic/palliative care) with fairness as the underlying ethical principle, planning for allocation of scarce resources among all involved sectors needs to be integrated and practiced. With thoughtful and realistic planning, the medical response in the chaotic environment may be made more effective and efficient for both victims and medical responders.

Summary
Executive Summary
Modern energy systems have been central to the development of human societies. They have perhaps been the single most important determinant of growth of our industrial societies and our modern economy. Unfortunately, they have also been a key driver of many of the negative environmental trends observed in the world today. For example, current energy systems are the predominant source of carbon dioxide (CO2) emissions, accounting for 84% of total global CO2 emissions and 64% of global greenhouse gas (GHG) emissions related to human activities. Past trends suggest that this percentage is likely to increase in the future if our energy needs continue to be met by fossil fuels.
The impact of GHG emissions on climate is arguably the most significant environmental impact associated with our energy systems, as the effects of such emissions are felt globally. However, these effects will not necessarily be equitable. Due to the realities of global and national economics, the areas that may suffer the greatest impacts from climate change may be those that have to date contributed the least in terms of GHG emissions. Our fossil fuel-based energy systems also emit substantial quantities of other atmospheric pollutants, for example sulphur dioxide (SO2), nitrogen oxides (NOx), primary particulate matter (PM), and non-methane volatile organic compounds (NMVOCs), which degrade air quality and cause damage to health and ecosystems through processes such as acidifi cation, eutrophication, and the formation of ground-level ozone (O3) and secondary PM. Biomass-based energy systems can also have substantial impacts on land and water resources.

Summary
Executive summary
Nature of the problem
Europe, and especially the European Union (EU), has many governmental policy measures aimed at decreasing unwanted reactive nitrogen (Nr) emissions from combustion, agriculture and urban wastes. Many of these policy measures have an ‘effects-based approach’, and focus on single Nr compounds, single sectors and either on air or waters.
This chapter addresses the origin, objectives and targets of EU policy measures related to Nr emissions, considers which instruments are being used to implement the policies and briefly discusses the effects of the policy measures.
Approaches
The chapter starts with a brief description of the basic elements of governmental policy measures.
A review of the main international conventions and EU policies related to emissions of Nr to air and water is then provided.
Finally the chapter provides a semi-quantitative assessment of the effectiveness and efficiency of European policy measures.
Key findings/state of knowledge
International conventions and other treaties have played a key role in raising awareness and establishing policy measures for Nr emissions abatement in EU through so-called Directives and Regulations.
There are many different EU Directives, often addressing individual Nr compounds from individual sectors (e.g. NOx emissions from combustion; NH3 emissions from agriculture, pollution of groundwater and surface water by nitrates from agriculture, discharge of total nitrogen from urban sewage to surface waters).

Summary
Executive summary
Nature of the problem
Single issue policies have been an effective means of reducing reactive nitrogen (Nr) emissions in the EU, but to make further reductions more-integrated approaches are required.
Approaches
This chapter shows how cost–benefit analysis (CBA) can provide guidance for the setting of new policy priorities for the abatement of the European Nr emissions from an integrated perspective.
Data on costs and benefits of Nr-abatement, including four national and regional case studies, are reviewed and made comparable by expression in euro per kg of added Nr (agriculture) or euro per kg of reduced Nr emission (unit cost approach).
Social cost estimates are based on Willingness to Pay (WTP) for human life or health, for ecosystem services and greenhouse gas (GHG) emission reduction.
Key findings
The total annual Nr-related damage in EU27 ranges between 70 and 320 billion Euro, equivalent to 150–750 euro/capita, of which about 75% is related to health damage and air pollution. This damage cost constitutes 1%–4% of the average European income.
Inferred social costs of health impacts from NOx are highest (10–30 euro per kg of pollutant-Nr emission). Health costs from secondary ammonium particles (2–20 euro/kg N), from GHG balance effects of N2O (5–15 euro/kg N), from ecosystem impacts via N-runoff (5–20 euro/kg N) and by N-deposition (2–10 euro/kg N) are intermediate. Costs of health impacts from NO3 in drinking water (0–4 euro/kg N) and by N2O via stratospheric ozone depletion (1–3 euro/kg N) are estimated to be low.

Summary
Air pollution is known to have a range of effects, including those on human health, crop production, soil acidification, visibility and corrosion of materials. This Chapter focuses on the two major impacts of air pollution that have most strongly influenced the development of policies to reduce emissions: those on the natural environment and on human health.
In broad terms, the major impacts of air pollution on the natural environment can be placed into three categories, representing different spatial scales:
Local impacts of major industrial or urban sources, for example, instances of damage to ecosystems and crop production close to emission sources. Historically, the biggest impacts have been through the direct effects of sulphur dioxide and particles – either around large point sources such as power stations and smelters, or in urban areas with domestic coal burning – and the accumulation of toxic metals in soils around smelters. However, a range of other pollutants from specific local sources can have direct impacts on vegetation.
Regional impacts of ozone, which is a significant global air pollutant in terms of impacts on vegetation, since high concentrations are found in rural areas.
Regional impacts of long-Range Transport and deposition of sulphur and nitrogen, which have effects on soil acidity, nutrient availability and water chemistry, and hence on ecosystem composition and function.
The Chapter first considers direct effects of air pollution on vegetation and the visible symptoms of damage that can result, illustrating the spatial variation in damage by reference to national and local studies in the Netherlands.

Native upland species, Nardus stricta, Eriophorum vaginatum, Erica cinerea and Vaccinium vitis-idaea were given 3 or 60 kg N ha−1 yr−1, over 2 yr, applied as a mist (NH4NO3). The high N treatment increased above-ground biomass in all four species, but only significantly in E. cinerea, E. vaginatum and N. stricta. Biomass increases in E. vaginatum and N. stricta resulted from enhanced tiller production rather than shoot elongation. Root growth increased in N. stricta, so that root[ratio ]shoot ratio in this species was unchanged by N. Root growth in E. vaginatum, E. cinerea and V. vitis-idaea did not respond to N and their root[ratio ]shoot ratios decreased. Tissue N concentrations increased in both shoots and roots of all species in response to N. The accumulated foliar N did not increase the proportion of N allocated to Rubisco and the photosynthetic capacities of N. stricta, E. vaginatum and V. vitis-idaea were unchanged. Thus growth responses to N were due to altered allocation rather than increased rate of photosynthesis per unit leaf area. The high N treatment increased flower production significantly in E. cinerea but not in the other species. Although in this experiment dwarf shrubs were more responsive than graminoids to N, in the field at current N inputs the enhanced tillering of the graminoids may be more competitively advantageous, especially where gaps develop in the canopy. Thus increasing N deposition may lead to increased grassiness of upland heath, and in particular, a spread of N. stricta.
