The loss of personal privacy and its consequences for social research
No full textThis article chronicles more than 30 years of public opinion, politics, and law and policy on privacy and confidentiality that have had far-reaching consequences for access by the social research community to administrative and statistical records produced by government. A hostile political environment, public controversy over the decennial census long form, media coverage, and public fears about the vast accumulations of personal information by the private sector were catalysts for a recent proposal by the U.S. Bureau of the Census that would have significantly altered the contents of the 2000 census Public Use Microdata Sample (PUMS). These events show clearly that science does not operate independently from the political sphere but may be transformed by a political world where powerful interests lead government agencies to assume responsibility for privacy protection that can result in reducing access to statistical data
The first fossil of a bolbitidoid fern belongs to the early-divergent lineages of elaphoglossum (dryopteridaceae)
No full textPremise of the study: Closing gaps in the fossil record and elucidating phylogenetic relationships of mostly incomplete fossils are major challenges in the reconstruction of the diversification of fern lineages through time. The cosmopolitan family Dryopteridaceae represents one of the most species-rich families of leptosporangiate ferns, yet its fossil record is sparse and poorly understood. Here, we describe a fern inclusion in Miocene Dominican amber and investigate its relationships to extant Dryopteridaceae. Methods: The morphology of the fossil was compared with descriptions of extant ferns, resulting in it being tentatively assigned to the bolbitidoid fern genus Elaphoglossum. This assignment was confirmed by reconstructing the evolution of the morphological characters preserved in the inclusion on a molecular phylogeny of 158 extant bolbitidoid ferns. To assess the morphology-based assignment of the fossil to Elaphoglossum, we examined DNA-calibrated divergence time estimates against the age of the amber deposits from which it came. Key results: The fossil belongs to Elaphoglossum and is the first of a bolbitidoid fern. Its assignment to a particular section of Elaphoglossum could not be determined; however, sects. Lepidoglossa, Polytrichia, and Setosa can be discounted because the fossil lacks subulate scales or scales with acicular marginal hairs. Thus, the fossil might belong to either sects. Amygdalifolia, Wrightiana, Elaphoglossum, or Squamipedia or to an extinct lineage. Conclusions: The discovery of a Miocene Elaphoglossum fossil provides remarkable support to current molecular clock-based estimates of the diversification of these ferns
