Cross-National Perspectives for Aiding Policy Choice

The field of public policy analysis, centered about practical choices, is being extended by this journal to include useful comparisons among nations or other political units, as well as borrowing or lesson-drawing. This extension should remain close to the practical orientation of the field, rather than seeking to contribute to those disciplinary theories that lack practical usefulness in the short term (several decades). Implications of this admonition are spelled out in the form of a list of suggested topics for articles in this journal.     

Political Identity,Public Memory and Urban Space: A Case Study of Parcul Carol I,Bucharest from 1906 to the Present

This article analyses the inter-relationship between political identity, public memory and urban space in South-east Europe through a case study of Parcul Carol I (Carol I Park) in Bucharest, Romania from 1906 to the present. The article analyses how the urban cultural landscape has been reshaped to support the political ambitions of three successive regimes—Romania as a kingdom and liberal constitutional monarchy (1881–1938); state-socialist Romania (1947–1989); and the post-socialist Romanian state from 1989. The article highlights complex continuity from the state-socialist period under post-socialism, rather than destruction of the landscape of state-socialism, combined with the return of pre-socialist landscape elements. The article argues for the need for studies of the fate of state-socialist urban landscapes under post-socialism which consider the complexities introduced by the persistence of landscape elements from the pre-socialist and state-socialist periods and their combination with pre-socialist and post-socialist landscapes to produce hybrid memory-scapes and spaces of the nation.     

Expertise in Fingerprint Identification

Although fingerprint experts have presented evidence in criminal courts for more than a century, there have been few scientific investigations of the human capacity to discriminate these patterns. A recent latent print matching experiment shows that qualified, court‐practicing fingerprint experts are exceedingly accurate (and more conservative) compared with novices, but they do make errors. Here, a rationale for the design of this experiment is provided. We argue that fidelity, generalizability, and control must be balanced to answer important research questions; that the proficiency and competence of fingerprint examiners are best determined when experiments include highly similar print pairs, in a signal detection paradigm, where the ground truth is known; and that inferring from this experiment the statement “The error rate of fingerprint identification is 0.68%” would be unjustified. In closing, the ramifications of these findings for the future psychological study of forensic expertise and the implications for expert testimony and public policy are considered.     

Impacts of abstinence education on teen sexual activity, risk of pregnancy, and risk of sexually transmitted diseases.

This paper examines the impacts of four abstinence-only education programs on adolescent sexual activity and risks of pregnancy and sexually transmitted diseases (STDs). Based on an experimental design, the impact analysis uses survey data collected in 2005 and early 2006 from more than 2,000 teens who had been randomly assigned to either a program group that was eligible to participate in one of the four programs or a control group that was not. The findings show no significant impact on teen sexual activity, no differences in rates of unprotected sex, and some impacts on knowledge of STDs and perceived effectiveness of condoms and birth control pills     

The Macroeconomic Effects of 2017 Through 2025 Federal Fuel Economy and Greenhouse Gas Emissions Standards

In the absence of a national carbon price, the federal Corporate Average Fuel Economy standards and the related greenhouse gas emissions (GHG) standards are the primary mechanisms through which the U.S. reduces transportation GHG emissions. In 2012, these standards were set to rise for light‐duty vehicles between 2017 and 2025, eventually achieving a target of 54.5 miles per gallon in 2025. Since 2012, conditions have changed: forecasts of future gasoline prices have dropped dramatically, consumers have demanded larger vehicles, and the cost of compliance appears to be larger than previously thought. In this article, we analyze the possible macroeconomic effects of the standards with both 2012 inputs and updated inputs to reflect these new market developments. The results reveal that the short‐term effects of the federal standards will be negative, but the long‐term effects will be positive, using both 2012 and updated inputs. The transition from annual negative employment impacts to positive impacts occurs between 2023 and 2026, depending on which set of assumptions are used. Possible revisions to the standards that freeze them at 2020 levels or decrease their stringency reduce short‐term negative impacts but also reduce long‐term positive impacts. We conclude with a discussion of policy implications as they relate to the current energy and climate policy conditions.     

Raman Microspectroscopic Mapping: A Tool for Identification of Fused Materials in Fire Debris

Examination of fire debris can provide information about the types of materials which were present at the time of the fire to give insights for fire scene reconstruction and understanding compartment fire dynamics. This paper demonstrates the ability of Raman spectroscopy for material identification postfire in complex situations, such as the production of fused masses during fire dropdown. A validated Raman spectral library is combined with Raman mapping in three fire case studies, to determine the individual materials in the fused masses formed. The case studies accessed material combinations of several common polymers. Raman mapping was carried out on a 10 μm × 10 μm square of the masses. Material identification using this technique ranged from a high of 85% match to a low of 40% match. This work demonstrated that complex masses found in the fire debris can be resolved into the individual material components for identification and spatial distribution.
