Review of The Canadian Prairies: A History By Gerald Friesen
No full textIn The Canadian Prairies, Gerald Friesen has taken on a monumental task. Over the past generation prairie historiography has grown too rapidly to lend itself to synoptic treatments. It would therefore be unreasonable to expect specialists to be entirely satisfied with Friesen\u27s treatment of their aspects of prairie history. I know I would like to edit his remarks on prairie literature, yet my informal inquiries suggest that this book is highly respected both by professional historians and by prairie pioneers, who find that Friesen\u27s narration rings true to their actual experiences. One of Friesen\u27s greatest achievements is in making of prairie history a lucid, readable, often entertaining narrative without denying its complexity. He outlines the main directions of scholarship on the principal issues, providing notes and bibliographical advice for further study. He strives to present contrary views with detachment, and often achieves a balance that clarifies contentious issues. This is particularly evident in his four excellent chapters on the native peoples and the fur trade, areas where questions of moral culpability have often overshadowed those of national achievement. By raising rather than adopting the arguments of the revisionists, Friesen delivers the questions alive and whole. He also identifies important gaps in the study of the prairie past; most notably in basic sociological research. Yet he manages to sketch a reasonably full and human picture with the limited data available
Butterflies and Flowers of Santiago, Nuevo León, Mexico
No full textWe hypothesized that both butterfly and flower abundance and species richness would be higher following an uncontrolled forest fire near the hamlet of Cienega de Gonzalez, Nuevo Leon, Mexico compared with the butterfly assemblage in an unburned forest near the hamlet of Las Guacamayas, NL. We also hypothesized that butterfly generalists would be more abundant in the burned site than in the control site. We used two different methods to survey butterfly assemblages: Pollard walk-and-count transects and Van Sømeren Rydon trapping. Flowers were recorded while conducting transect surveys. These data clearly show that the butterfly and flower communities were both more abundant and species rich in the burned site. Generalists were more common in the burned sites than control sites, specialists were equally abundant in control and burned sites.

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
Phylogeny and New Intrageneric Classification of Allium (Alliaceae) Based on Nuclear Ribosomal DNA ITS Sequences
No full textThe internal transcribed spacer region (ITS) of nuclear ribosomal DNA was sequenced from 195 representative species of Allium, two species of Nothoscordum, and one species each of lpheion, Dichelostemma, and Tulbaghia. Within the Allium species the lengths of the ITS regions were in a range from 612 to 661 base pairs and pairwise genetic distances reached up to 46%. The ITS data supported the inclusion of Nectaroscordum, Caloscordum, and Milula into Allium. Subgenera Rhizirideum and Allium, as well as sects. Reticulatobulbosa and Oreiprason were non-monophyletic taxa. Based on the phylogenetic relations, a new classification of genus Allium consisting of 15 monophyletic subgenera is presented. Sections Microscordum, Anguinum, Porphyroprason, Vvedenskya, Butomissa, Cyathophora, and Reticulatobulbosa are raised to subgeneric rank. Sections Austromontana N. Friesen, Eduardia N. Friesen, Mediasia F. O. Khassanov, S. C. Yengalycheva et N. Friesen, Nigrimontana N. Friesen, Falcatifolia N. Friesen, and Condensatum N. Friesen are newly described. Series Daghestanica, Pallasia, and Scabriscapa, as well as subsects. Eremoprasum, Longivaginata, and Sikkimensia are raised to sectional rank. A taxonomic conspectus of Allium at sectional level is given
"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
Letter from R. R. Zellick, Assistant Trust Officer, Anglo California National Bank of San Francisco, to Joseph R. Goodman, October 2, 1942
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. Included in the collection are records of the Japanese Young Men's Christian Association and the Japanese American Citizens' League in San Francisco, including papers of the Japanese YMCA's executive secretary Lincoln Kanai; Sakai family papers; Goodman's correspondence to and from Japanese American incarcerees, organizations opposing forced removal and incarceration of Japanese Americans, the War Relocation Authority, and others; publications, photographs, and ephemera from the Topaz Relocation Center, where Goodman taught high school; War Relocation Authority records and publications; and newspaper clippings, pamphlets, and reports about forced removal and incarceration created by various government, religious, and civic organizations, in California and nationwide

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
Introduction: The Intersections of Inequality, Migration and Diversification
No full textInequality, or the rise of disparities within populations, and human migration constitute two of the major challenges facing societies today. In highlighting the close links between them, scholarship has principally focused on extant inequalities between migrant and non-migrant groups. In this introductory chapter, we argue that diversification in contemporary migration policies in Anglophone labour-receiving societies produces inequalities between, among and within migrant groups that also demand urgent attention. The chapter further outlines the core precepts informing this book. Firstly, migrants are a heterogeneous group who are increasingly stratified in ways unconnected to their ethnic or national differences. Secondly, inequalities among migrants are produced in the complex intersections of race, class, gender, legal status, sexuality, age and histories of settlement. Finally, inequality manifests in diverse and localised forms affecting access to income, wealth, opportunity, well-being and social and political capital. The chapters that follow both empirically ground and theoretically develop these foundational arguments within employment and the labour market, housing, adolescent well-being, urban planning, multicultural policy and electoral politics.https://catalogue.library.auckland.ac.nz/permalink/f/t37c0t/uoa_alma5130619933000209
