Chan An Ancient Maya Farming Community
No full textThe farming community of Chan thrived for over twenty centuries, surpassing the longevity of many larger Maya urban centers. Between 800 BC and 1200 AD it was a major food production center, and this collection of essays reveals the important role played by Maya farmers in the development of ancient Maya society. Chan offers a synthesis of compelling and groundbreaking discoveries gathered over ten years of research at this one archaeological site in Belize. The contributors develop three central themes, which structure the book. They examine how sustainable farming practices maintained the surrounding forest, allowing the community to exist for two millennia. They trace the origins of elite Maya state religion to the complex religious belief system developed in small communities such as Chan. Finally, they describe how the group-focused political strategies employed by local leaders differed from the highly hierarchical strategies of the Classic Maya kings in their large cities. In breadth, methodology, and findings, this volume scales new heights in the study of Maya society and culture.Cover -- Title -- Copyright -- Contents -- List of Figures -- List of Tables -- Foreword -- Acknowledgments -- 1.

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
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

Glucokinase activity in isolated islets from obese fa/fa Zucker rats
No full textGlucokinase (EC 2.7.1.2) activity of B-cells was measured in extracted pancreatic islets isolated from lean and obese fa/fa Zucker rats and maintained in primary culture overnight. Formation of [14C]glucose phosphoric esters from D-[U-14C]glucose was measured in the presence of unlabelled glucose from 0.05 to 0.50 mM for hexokinase (EC 2.7.1.1) activity, and 8.0-16.0 mM unlabelled glucose for glucokinase activity. Eadie-Hofstee analysis revealed that hexokinase kinetic parameters (Vmax and Km) for [14C]glucose phosphoric ester formation were similar in lean- and fa/fa-rat islets. For glucokinase, there was no difference in Vmax. between phenotypes. A non-significant tendency to increased sensitivity to glucose was noted in the fa/fa-rat islets (P = 0.13). In lean-rat islets, the glucokinase inhibitor mannoheptulose (3 mM) decreased Vmax. by 80% and increased the apparent Km from 3.3 +/- 0.7 mM to 12.2 +/- 2.0 mM (P < 0.05). There was no difference in Km or Vmax. in mannoheptulose-treated versus control islets from fa/fa rats. This lack of effect was consistent with reported effects of mannoheptulose on insulin secretion from fa/fa-rat islets [Chan, MacPhail and Mitton (1993) Can. J. Physiol. Pharmacol. 71, 34-39]. The data from glucose and mannoheptulose experiments support the hypothesis that glucokinase function is altered in fa/fa Zucker rats and may contribute to fasting hyperinsulinaemia in vivo in these animals.LR: 20061115; PUBM: Print; JID: 2984726R; 11061-68-0 (Insulin); 654-29-5 (Mannoheptulose); EC 2.7.1.1 (Hexokinase); EC 2.7.1.2 (Glucokinase); ppublishSource type: Electronic(1
