Reconciling and translating migration data collected over time intervals of different widths
No full textIn this paper we describe and contrast the age and spatial structures of migration identified by data collected over one-year and five-year time intervals, by focusing, in particular, on the generation and distribution components of age- and origin-destination-specific migration flows. We explore the contributions of primary, return, and onward migration defined by fixed interval migration data, and we outline a crude translation procedure for transforming the one-year migration flow data into an estimated five-year counterpart. The data used in this study represent several migration periods drawn from recent U.S. and Canadian censuses and surveys. Differences between the structures exhibited by U.S. and Canadian migration patterns, collected over one-year and five-year migration time intervals, are carefully examined and contrasted.
Versions of this paper were presented in February, 2002 at the annual meetings of the Western Regional Science Association in Monterey, California and in May, 2002 at the annual meetings of the Population Association of America in Atlanta, Georgia. The authors would like to thank Professor Frans Willekens at the University of Groningen in the Netherlands for his collaboration on earlier work that focused on migration spatial structure, of which this paper is a continuation. Also, our appreciation goes to the three anonymous reviewers for their comments and suggestions

Antigens on the Plasmodium falciparum infected erythrocyte surface are parasite derived: a reply.
No full textIn this article Chris Newbold and Kevin Marsh describe the evidence for the co-existence of both modified host proteins and of parasite determinants at the infected erythrocyte surface. The stable characteristics of infected cells may in part stem from parasite-induced changes in band 3 molecules, thus explaining some of the cytoadherence properties of uninfected, but abnormal cells (as in sickle-cell disease and diabetes). However, Newbold and Marsh suggest that it is difficult to explain the astonishing diversity of antigens that have been observed at the surface of infected red cells unless such molecules have been synthesized by the parasite

A well-conserved Plasmodium falciparum var gene shows an unusual stage-specific transcript pattern
No full textThe var multicopy gene family encodes Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) variant antigens, which, through their ability to adhere to a variety of host receptors, are thought to be important virulence factors. The predominant expression of a single cytoadherent PfEMP1 type on an infected red blood cell, and the switching between different PfEMP1 types to evade host protective antibody responses, are processes thought to be controlled at the transcriptional level. Contradictory data have been published on the timing of var gene transcription. Reverse transcription-polymerase chain reaction (RT-PCR) data suggested that transcription of the predominant var gene occurs in the later (pigmented trophozoite) stages, whereas Northern blot data indicated such transcripts only in early (ring) stages. We investigated this discrepancy by Northern blot, with probes covering a diverse var gene repertoire. We confirm that almost all var transcript types were detected only in ring stages. However, one type, the well-conserved varCSA transcript, was present constitutively in different laboratory parasites and does not appear to undergo antigenic variation. Although varCSA has been shown to encode a chondroitin sulphate A (CSA)-binding PfEMP1, we find that the presence of full-length varCSA transcripts does not correlate with the CSA-binding phenotype
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
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
