Re: Link Stability Estimation Based on Link Connectivity Changes in Mobile Ad-hoc Networks
I have not been able to assess if this is an author version peer-reviewed or is it an author version non peer reviewed. Could you please clarify this so I can proceed to add your paper to Spiral. Spiral digital repository only accept peer-reviewed papers.

Manual constitucional para la práctica de IVE. Lineamientos constitucionales para el ejercicio del derecho al aborto en Colombia
No full textLos derechos y obligaciones constitucionales frente a la prestación del servicio
de aborto, reconocidos a partir de la sentencia C-355/06 y la jurisprudencia posterior
de la Corte Constitucional, tienen plena vigencia. Sin embargo, la suspensión
del Decreto Reglamentario 4444 del Ministerio de Protección Social por parte
del Consejo de Estado, ha creado una confusión generalizada que puede
poner en peligro los derechos a la vida, a la salud, a la integridad personal y a la
dignidad humana de las mujeres colombianas. Por esta razón Women´s Link
Worldwide decide elaborar esta publicación, que compila de manera sistemática
los diferentes lineamientos constitucionales que deben seguirse para la práctica
de interrupciones voluntarias del embarazo (IVE
Simulations and interpretations of cumulative trophic theory
No full textExamining marine ecosystems in a distinct way can produce new ecological, theoretical and applied insights. The common “S” and “hockey stick” -shaped curves, which result from examining the cumulative biomass and trophic level and the cumulative production and cumulative biomass curves of marine ecosystems, have strong potential to elucidate the mechanisms of marine food webs. These curves are based on the cumulative trophic theory, which can be summarized as the integration of biomass and production across trophic level that results from the relatively simple trophic transfer equation. Here we test the behavior of this theory via modeled simulations of the transfer equation under a variety of common mechanisms that can influence marine ecosystems. The simulated scenarios we present and evaluate here explore bottom-up driven changes (production, growth), internal dynamics (transfer efficiency) or top-down driven changes (mortality, selectivity), as well as multi-mechanism scenarios (overfishing and eutrophication) that are commonly experienced in marine ecosystems. We explore these scenarios at high, medium or low levels of change for each feature to ascertain how they can result in major changes to the realized trophodynamics of a marine ecosystem. Our results lend credence to the generality of the cumulative trophic theory by predicting the empirically observed “S” and “hockey stick” -shaped curves under a wide range of possible mechanisms. Given that common, repeatable and predictable dynamics is a key hallmark of increasingly robust theories, the application of cumulative trophic theory in managing marine ecosystems enables more repeatable and predictable responses across a wide range of conditions
An initial exploration of the link relationship between UK university Web sites.
No full textAggregates of links are of interest to information scientists in the same way as citation counts are: as potential sources of data from which new knowledge can be mined. Builds on the recent discovery of a correlation between a Web link count measure and the research quality of British universities by applying a range of multivariate statistical techniques to counts of links between pairs of universities. This represents an initial attempt at developing an understanding of this phenomenon. Extracts plausible results. Also identifies outliers in the data by the techniques, some of which were verified by being tracked down to identifiable Web phenomena. This is an important outcome because successful anomaly identification is a precondition to more effective analysis of this kind of data. The identification of groupings is encouraging evidence that Web links between universities can be mined for significant results, although it is clear that more methodological development is needed, if any but the simplest patterns are to be extracted. Finally, based upon the types of patterns extracted, argues that none of the methods used are capable of fully analysing link structures on their own
Quantitative genetic analysis of embryo heterosis in faba bean (Vicia faba L.)
No full textSeeds, i.e. embryos, may be genetically different from either of their parents and moreover may express their own heterosis. The objective was to genetically analyse embryo heterosis for their own weight (i.e. seed weight) in comparison with their seedlings' heterosis, taking the large-seeded crop (Vicia faba L.) as model. A specific diallel mating scheme was used, based on four parental lines, creating 76 seed genotypes in generations P, F(1), F(2) and BC. Mature seed weight was assessed for these embryo genotypes in 3 years at one German location, and young plant biomass yield of seedlings emerging from these seeds in two greenhouse experiments. The quantitative genetic analysis showed an average of 10.6% mid-parent heterosis for mature seed weight and 14.5% mid-parent heterosis for juvenile biomass. In both traits, the embryos contributed markedly and significantly via their own genes to the genetic variation. For mature embryo weight heterosis, apparently the parental difference in seed weight was decisive, whereas for juvenile biomass heterosis, genetic unrelatedness of parents had priority.DFG [SPP1149
Link Services or Link Agents?
No full textA general link service for the WWW has been used within an Electronic Libraries' project. Experience using it shows that as the links become increasingly interesting to the user, processing them becomes increasingly expensive. Eventually textual analysis, ontological services and remote database lookups conflict with the goal of prompt delivery of documents. This paper summarizes the history of the Link Service software behind the Open Journal project together with the kind of links that it has been used to produce. Building on this work it then discusses how the paradigm, architecture and user interface of the DLS have been newly modified both in response to user feedback and also to allow more linking facilities to be added to the WWW environment. We then introduce AgentDLS, an agent-style system that offers suggestions to help the user's browsing and information discovery activities

Dynamic Link Inclusion in Online PDF Journals
No full textTwo complementary de facto standards for the publication of electronic documents are HTML on theWorldWideWeb and Adobe s PDF (Portable Document Format) language for use with Acrobat viewers. Both these formats provide support for hypertext features to be embedded within documents. We present a method, which allows links and other hypertext material to be kept in an abstract form in separate link databases. The links can then be interpreted or compiled at any stage and applied, in the correct format to some specific representation such as HTML or PDF. This approach is of great value in keeping hyperlinks relevant, up-to-date and in a form which is independent of the finally delivered electronic document format. Four models are discussed for allowing publishers to insert links into documents at a late stage. The techniques discussed have been implemented using a combination of Acrobat plug-ins, Web servers and Web browsers
