Supporting data for "Direct tracking of pollen with quantum dots reveals surprising uniformity in dispersal distance across eleven populations of an annual plant"
No full textPollen movement is a crucial component of dispersal in seed plants. We used quantum dot pollen labeling, a new technique that overcomes past limitations, to evaluate the spatial scale of pollen dispersal and its relationship with conspecific density within eleven populations of Clarkia xantiana ssp. xantiana, a bee pollinated, annual plant. We used experimental arrays in two years to track pollen movement across distances of 5 – 35 m within nine populations and across distances of 10 – 70 m within two additional populations. We tested for distance decay of pollen dispersal and whether conspecific density modulated dispersal distance. We also asked whether dispersal kernels varied among populations across an environmentally complex landscape. We did not observe a decline in labeled pollen receipt with distance over 35 m within eight of nine populations or over 70 m within either of two populations. Pollen receipt increased with conspecific density. Overall, dispersal kernels were consistent across populations.National Science Foundation (DEB-1754246)National Science Foundation (DEB-1754026)Bell Museum of Natural History (U. of Minnesota)Kern, Brooke R; Carley, Lauren N; Moeller, David A.

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Resemble those of S. benedettii, S. modesta and S. moonenorum sp. nov. by the embolus and paraembolic apophysis pointing forward (Figs 51–52) and S. benedettii by the flat shape of paraembolic apophysis (Figs 75–77). Females unknown. Etymology The name is in honor of the Wayana indigenous group, natives of the eastern region of the Pará State in Brazil.
