Genomic characterization of multi-parental populations of sorghum and rice
No full textThis thesis describes research work performed at the University of Illinois at Urbana- Champaign (UIUC) and the International Rice Research Institute (IRRI) on genetic analysis of two important cereal crops, sorghum and rice. Research presented in chapters 1 and 2 was performed at UIUC under the supervision of Dr. Patrick J. Brown, and research presented in chapter 3 was performed at IRRI under the supervision of Dr. Kenneth L. McNally.
Sorghum is the world’s fifth most important cereal crop and is critical for food security in semi-arid regions. Chapter 1 describes the generation of genetic linkage maps for eight sorghum recombinant inbred line (RIL) populations using genotyping-by-sequencing (GBS) data. In this work, 1626 RILs from eight biparental populations were genotyped using a modified GBS protocol with Y-adapters. For SNP calling used the TASSEL5 GBS pipeline, and genetic linkage maps were produced using ASMap, an R package that implements MSTMap algorithm. Chapter 2 describes the skim (~5X) sequencing of 240 bioenergy sorghum genomes, using a whole-genome sequencing library preparation protocol that was developed in-house and is cost- effective and less labor-intensive than existing methods.
Rice is a staple food for most of the world’s population, and 90% of the rice produced globally is used for human consumption. Rice production requires a significant amount of fresh water. Drought is one of the major abiotic stresses of rice and is responsible for up to 40% yield loss of total world production, annually. Modern rice cultivars have lost most of their genetic diversity, and the use of crop wild relatives (CWRs) in breeding needs to be explored. IRRI has developed four backcross introgression line (BIL) populations using wild progenitors of Asian cultivated rice as donor parents. Chapter 3 describes the genotype data analysis of these four populations and phenotyping of a subset of each of the four populations under well-watered and managed water stress conditions. This field experiment was conducted at IRRI in the Philippines during the 2018 dry season. Analysis of phenotype data collected for the subsets indicates considerable genotypic variation, and researchers have shown interest in using these lines in their breeding programs. A total of sixteen lines, four from each population, were selected based on the 2018 DS and are being tested at IRRI for physiological traits.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-12-01The student, Pradeepa Hirannaiah, accepted the attached license on 2019-11-05 at 15:40.The student, Pradeepa Hirannaiah, submitted this Dissertation for approval on 2019-11-05 at 15:42.This Dissertation was approved for publication on 2019-11-06 at 15:55.DSpace SAF Submission Ingestion Package generated from Vireo submission #14529 on 2020-02-28 at 17:21:49Made available in DSpace on 2020-03-02T22:12:16Z (GMT).

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

No full textLetter from R. R. Zellick, Assistant Trust Officer at The Anglo California National Bank of San Francisco, to Joseph R. Goodman, regarding property owned by Dave Tatsuno. Zellick mentions a dispute between current tenants and Tatsuno, and that Tatsuno has asked Goodman to help locate trustworthy tenants.Personal correspondence, organizational records, government documents, publications, and other papers created or collected by Joseph R. Goodman documenting the forced removal and incarceration of Japanese Americans during World War II, as well as organized resistance to incarceration.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
