Evaluation of the Enhanced Computational Methods of Estimating Age-at-Death Using the Pubic Symphyses of a White South African Population

To address problems of reproducibility related to current age estimation methods, the enhanced computational Methods (ECM) were previously developed using a sample of white North American male pubic symphyses and showed promise in improving current techniques. However, given the evidence of sex and population differences in the onset of age markers, this study set out to test the ECM on a white South African sample. The sample consisted of 184 well-preserved os coxae from individuals of known age and sex. Pubic symphyseal surfaces were scanned using the Artec Spider 3D scanner, processed using Artec Studio 10 and analyzed using forAge. Point estimates of age were then compared to the true age of each individual. Results indicate that the ECM performed poorly in a white South African population, with consistent underestimation of age-at-death and weak positive correlations with true age. Despite the low correlations, the ECM did, however, reduce observer error.     

Advances in Osteometric Sorting: Utilizing Diaphyseal CSG Properties for Lower Limb Skeletal Pair-Matching

Pair-matching of bilateral elements is a major component of resolving commingled remains both in forensic and bioarchaeological contexts. This study presents a new method of osteometric pair-matching of the lower limbs which relies on 3D digital models of the femur and tibia bones. The proposed method, which is accompanied by a freely available open-source implementation, automatically computes a number of osteometric variables including cross-sectional geometric properties from an assemblage of left and right bone antimeres and calculates probabilistically the appropriate matching pairs as well as single elements, whose bones antimere is not present in the given assemblage. The method has been extensively tested on a skeletal sample comprising 396 femurs and 422 tibias from the Athens collection. Our results in testing commingled assemblages with no disparity show that the method’s sensitivity is 1 for sorting femurs and 0.997 for sorting tibias, whereas in assemblages with moderate disparity the sensitivity is 0.999 and 0.992 respectively. Our results further indicate that sensitivity is unaffected by the size of the commingled assemblage although the percentage of identified true matching pairs drops as the number of commingled elements increases. This means that all identified antimeres matched to an individual are still very accurately sorted despite not every individual being identified in very large assemblages. The proposed method can facilitate the sorting process of commingled remains both accurately and efficiently, while leaving a very small percentage of unsorted elements that may require further techniques for further individualization.     

Inside Lobbying on the Regulation of New Plant Breeding Techniques in the European Union: Determinants of Venue Choices

In July 2018, the Court of Justice of the European Union decided that new plant breeding techniques (NPBTs) fall within the scope of the restrictive provisions on genetically modified organisms (GMOs). Previously, various actors had lobbied in order to influence the European Union’s (EU’s) regulatory decision on NPBTs. This study examines the venue choices taken by Cibus, a biotech company that promoted NPBT deregulation. It shows that the firm bypassed the EU level and that it lobbied competent authorities (CAs) in certain member states to gain support for the deregulation of NPBTs. Cibus chose the CAs because their institutional “closedness” reduced the risk of the debate over the deregulation of NPBTs becoming public. However, the CA’s specific competences and their influence on EU decision making were of likewise importance. The firm lobbied CAs based in Finland, Germany, Ireland, Sweden, Spain, and the United Kingdom. Two factors appear to have influenced Cibus’ choices for these countries: high‐level political support for agribiotech and the high relevance of biotech sectors. In contrast, public support for GMOs turned out to have hardly any influence, and virtually no association could be observed for the agricultural application of biotechnology in the past nor for the weakness of domestic anti‐GMO lobby groups. Finally, the in‐depth study on Germany affirms that “closedness” was important for Cibus’ choices and reveals that technical information served as a venue‐internal factor that influenced the firm’s choices.     

The Political Viability of Carbon Pricing: Policy Design and Framing in British Columbia and California

The adoption of climate policies with visible, substantial costs for households is uncommon because of expected political backlash, but British Columbia's carbon tax and California's cap‐and‐trade program imposed such costs and still survived vigorous opposition. To explain these outcomes, this article tests hypotheses concerning policy design, framing, energy prices, and elections. It conducts universalizing and variation‐finding comparisons across three subcases in the two jurisdictions and uses primary sources to carry out process tracing involving mechanisms of public opinion and elite position‐taking. The article finds strong support for the timing of independent energy price changes, exogenous causes of election results, reducing the visibility of carbon pricing, and using public‐benefit justifications, as well as some support for making concessions to voters. By contrast, the effects of the use of revenue, industry exemptions/compensations, and making polluters pay are not uniform, because the effects of revenue use depend on how it is embedded in coalition building efforts and a middle path between exempting or compensating industry and burdening it appears to be more effective than pursuing just one or the other approach.     

Science and Technology for Economic Growth. New Insights from when the Data Contradicts Desktop Models1

Science and technology policy initiatives in the early 1980s have focused in both the United States and Western Europe on improving capacity to apply a good science base in practice, expecting increases in technological advancement, improved market presence and enhanced economic growth. Results varied broadly in the United States and Europe. Even more puzzling, Japan charged ahead in technological advancement without that strong of a science base of its own. Some industrialized economies do not conform to the expected science–technology relationship, whereby strong performance in science shall lead to strong technological performance. The puzzling science–technology relationship in advanced countries has plausible explanations. (1) Science–technology relationship is much interdependent or symbiotic. Its strength and primary direction at a given time varies largely by field of science or technological innovation and across long periods of time. (2) Science–technology link in a country may depend on the overall scientific and technological level of development in that country. The strength and interdependent nature of this link evolves historically and varies across fields of science and technology. The strength of the link is affected by scientific and technological specialization in a country. Different technological fields have different scientific intensities, or degrees of building upon the science base. (3) Specialization of countries across scientific and technological fields varies. Hence, the strength of science–technology link differs between countries. High technological specialization of a country may impact its technological performance more than its immediately current scientific performance does. History, tradition and knowledge transfers may affect more returns on R&D expenditures than the actual value of R&D funds spent in science or technology. Explanations of puzzling behavior of science–technology link may become policy recommendations.

Political Ideology,Political Party,and Support for Greater Federal Spending on Environmental Protection in the United States: Evidence from the General Social Surveys, 1993–2018

This paper focuses on the effects of political ideology and party affiliation on support for more government spending on environmental protection. Pooled‐sample results show that Liberals (Democrats) are more likely to support higher government spending on environmental protection than Moderates (Independents), who, in turn, are more likely to support higher spending levels than Conservatives (Republicans). The results persist even when we control for respondents' opinions concerning whether the federal government, in general, does too little or too much. When stratifying by party, ideological divisions generally narrow, while stratifying by ideology leads to slightly wider divisions between Democrats and Republicans. Together, these results suggest that when Liberals and Conservatives form opinions about government spending on the environment, party affiliation, to some degree, dampens the effects of ideology. Between 2014 and 2018 the probability of supporting more environmental spending increased, albeit slightly, for all ideologies and parties, but more so for Liberals and Democrats.
