Unknown Medieval Fragments in German from the Ludwik Zalewski Collection at the Polish National Library, Warsaw
No full textAmong others, the Polish National Library possess a collection (MS 8098 IV) encompassing parchment fragments extracted from bookbindings, which contain German texts. This collection was acquired from the family of the deceased bibliophile from Lublin, Father Ludwik Zalewski. The collection consists of eleven parchment leaves, six of which form three bifolia, the other five being small fragments. The collection is known to historians, chiefly due to two of the bifolia, which contain fragments of an Old Saxon translation of the Psalms (Altsächsiche Psalmen). The rest of the fragments, dated chiefly by the author to the fourteenth century, are also of interest. J. Kaliszuk identifies them as belonging to: Der Welsche Gast by Thomasin von Zerklaere, the Christherre-Chronik and the Livländische Reimchronik. The author also demonstrates that this collection was put together by L. Zalewski, hence there is no possibility of tracing the provenance of individual fragments. The article is supplemented by two appendices, the first with codicological descriptions of the complete collection, and the second containing an edition of the letter from Stanisław Tomkowicz, an art historian from Cracow, to Ludwik Zalewski, written in 1916, concerning the fragments in question
Diabetes-linked zinc transporter ZnT8 is a homodimeric protein expressed by distinct rodent endocrine cell types in the pancreas and other glands
No full textCopyright © 2008 Elsevier B.V. All rights reserved.Background and aimsZinc is abundant in pancreas, being required by endocrine islet cells for hormone secretion and by exocrine acinar cells as pancreatic juice component. ZnT8 is a member of the SLC30A family of zinc transporters whose overexpression in cultured pancreatic beta cells leads to increased insulin secretion in response to glucose, suggesting a possible role in regulating glycemia. ZnT8 was therefore proposed as a therapeutic target for diabetes, and recent genome-wide association studies identified polymorphisms in the ZNT8 gene conferring increased type 2 diabetes risk.Methods and resultsAs limited information was available on the biochemical properties of ZnT8 and on its endogenous expression, we have raised a specific polyclonal antibody and immunostained protein extracts, cell lines and tissue sections. We show that ZnT8 forms a very stable dimer that requires biological membranes to properly assemble. We demonstrate localization of murine ZnT8 to the secretory granules in pancreatic beta and alpha islet cells. Moreover, we show that ZnT8 is also expressed in other secretory cell types, namely the cubical epithelium that lines thyroid follicles and the cortex of the adrenal gland, suggesting a more widespread role in endocrine secretion.ConclusionWe provide novel insights into the features of the ZnT8 transporter, of special relevance in light of its proposed role as therapeutical target for diabetes treatment.C.

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
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
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
