Metadata Authority Description Schema (MADS): uma alternativa à utilização do formato MARC 21 para dados de autoridade

Introduction: Authority records interchange requires establishing and using metadata standards, such as MARC 21 Format for Authority Data, format used by several cataloging agencies, and Metadata Authority Description Schema (MADS), that has received little attention and it is a little widespread standard among agencies. Purpose: Presenting an introductory study about Metadata Authority Description Schema (MADS). Methodology: Descriptive and exploratory bibliographic research. Results: The paper address the MADS creation context, its goals and its structure and key issues related to conversion of records from MARC 21 to MADS. Conclusions: The study concludes that, despite its limitations, MADS might be used to create simple authority records in Web environment and beyond libraries context.

Sintaxe e semântica de registros bibliográficos: princípios para a conversão de registros analógicos para o formato MARC21 bibliográfico: Scan for MARC

The research presents as its central theme the study of the bibliographic record conversion process. The object of study is framed by an understanding of analogic bibliographic record conversion to the Bibliograhpic MARC21 format, based on a syntactic and semantic analysis of records described according to descriptive metadata structure standards and content standards. The objective of this research the objective is to develop a theoretical-conceptual model of syntactic and semantic of bibliographic records, from Linguistic studies of Saussure and Hjelmslev of manifestations of human language, which subsidizes the development of a computacional interpreter, focused to the conversion of bibliographic records to MARC21 Bibliographic Format, which can be confirmed both the semantic value of the informational resource represented as the reliability of the representation. Given the aforementioned objectives, the methodological trajectory of the research is based on the qualitative approach, of an exploratory, descriptive and experimental nature, and with recourse to the literature. Contributions on the theoretical plane can be envisaged regarding the development of questions inherent to the syntactic and semantic aspects of bibliographic records, and by involving, at the same time, interdisciplinarity between Information Science, Computer Science and Linguistics. Contributions to the practical field are identified by the fact the study covers the development of the Scan for MARC, a computational interpreter that can be adopted by any institution that wishes to use the conversion procedure for bibliographic record databases to the MARC21 Bibliographic Format from description and visualization schemes of bibliographic records (AACR2r and ISBD), an aspect of the research which is considered innovative.

Subgroup-specific structural variation across 1,000 medulloblastoma genomes

Medulloblastoma, the most common malignant paediatric brain tumour, is currently treated with nonspecific cytotoxic therapies including surgery, whole-brain radiation, and aggressive chemotherapy. As medulloblastoma exhibits marked intertumoural heterogeneity, with at least four distinct molecular variants, previous attempts to identify targets for therapy have been underpowered because of small samples sizes. Here we report somatic copy number aberrations (SCNAs) in 1,087 unique medulloblastomas. SCNAs are common in medulloblastoma, and are predominantly subgroup-enriched. The most common region of focal copy number gain is a tandem duplication of SNCAIP, a gene associated with Parkinson's disease, which is exquisitely restricted to Group 4 alpha. Recurrent translocations of PVT1, including PVT1-MYC and PVT1-NDRG1, that arise through chromothripsis are restricted to Group 3. Numerous targetable SCNAs, including recurrent events targeting TGF-beta signalling in Group 3, and NF-kappa B signalling in Group 4, suggest future avenues for rational, targeted therapy.

MARC 21 e XML como ferramentas para a consolidação da catalogação cooperativa automatizada: Uma revisão de literatura

The cooperation and the sharing of information cataloguing and bibliographical in environment automated, this was only possible with the creation and adoption of interchange format MARC21. But due to the progresses of the technologies of information and communication, of the crescent use of Internet and of the databases and databanks, there were the need of the creation and development of tools that optimize the organization activities, retrieval and interchange of information. XML is one of those developments that have as purpose to facilitate the management, storage and transmission of data through Internet. Before that, it was proposed through a literature revision, to analyze Interchange Format MARC21 and Markup Language XML as tools for the consolidation of the Automated Cooperative Cataloguing, your differences of storage flexibilities, organization, retrieval and interchange of data through Internet. This research made possible the divulgation to the community librarian, through a literature revision, that has been discussed internationally on MARC21 and XML

Rechtshilfe in Zivilsachen: ausgewählte Auszüge aus der neuen Wegleitung des Bundesamtes für Justiz

Die vorliegenden Beiträge in deutscher und französischer Sprache befassen sich mit Aspekten der Rechtshilfe in internationalen Zivil- und Handelsprozessen. Zur Zustellung von gerichtlichen und aussergerichtlichen Urkunden sowie zur rechtshilfeweisen Beweiserhebung (z. B. Einvernahme mittels Videokonferenz) äussern sich Dr. Alexander Markus sowie Dr. Danielle Gauthey Ladner. Dabei wird insbesondere auf die neue Wegleitung des Bundesamtes für Justiz zu den verschiedenen Haager Übereinkommen eingegangen. Alexander Hilfiker erläutert die Möglichkeiten der Internet-Recherche. Die menschlich vielfach schwierigen Probleme der Kindesentführungen behandeln David Urwyler, Sonja Hauser und Hervé Boéchat. Auf aktuelle Fragen der Anerkennung und Vollstreckung von Zivilurteilen gehen Dr. Samuel Baumgartner und Jean-Marc Wichser ein. Das Thema Vollstreckung von ausländischen Konkurserkenntnissen ist Gegenstand der Beiträge von Prof. Dr. Karl Spühler und von Prof. Dr. Sylvain Marchand.
