The usability of research papers on the Web would be enhanced by a system that explicitly modelled the rhetorical relations between claims in related papers. We describe ClaiMaker, a system for modelling readers’ interpretations of the core content of papers. ClaiMaker provides tools to build a Semantic Web representation of the claims in research papers using an ontology of relations. We demonstrate how the system can be used to make inter-document queries.

Красимир Йорджев, Христина Костадинова - В работата се разглежда една релация на еквивалентност в множеството от всички квадратни бинарни матрици. Обсъдена е комбинаторната задача за намиране мощността и елементите на фактормножеството относно тази релация. Разгледана е и възможността за получаване на някои специални елементи на това фактормножество. Предложен е алгоритъм за решаване на поставените задачи. Получените в статията резултати намират приложение при описанието топологията на различните тъкачни структури.

Growing demand for handwoven Maya textiles from Guatemala parallels recent international fascination with Maya civilization. This thesis surveys the effects of increases in demands for artisan textiles in Guatemala, and explores the reactions of women involved in Aj Quen, a weavers' association. The hypothesis is that the well-being of Maya women depends on their participation in the association. This is tested by using indicators of the weavers' attitudes defined as their "well-being" regarding (1) health, (2) education levels, (3) child care practices, and (4) economic stability. Interviews were conducted with 127 Maya women. Data were documented, providing a crucial missing link in the current literature of "women in Guatemala." The results of this study yield baseline data demonstrating that health and child care practices are not directly related to women's participation in the association. Their education levels increased as a direct result of working with the association, as did economic stability, although less consistently.

This article explores forms of migrant families’ reorganization within a (new) global economic crisis and the hardening of migration control in Europe; based on the cases of Dominican and Brazilian migration to Spain.Our goal is not to characterize the wholeness of strategies from these collectives, instead visualize its heterogeneity. Displacement of Dominican and Brazilian population to Spain shares the role of women as the first link of migration chains. In both cases women are the economic support of transnational families and they lead reunification's processes. Nevertheless, differences in the time spent in the destination country, migratory status, origin (rural-urban), level of education, class and labor insertion in destination country, affect differently, the planning and start up of migration projects, the organization of care and family reunification strategies. These findings question the predominant place granted to national origin in the study of international migration.

Background: Several materials have been used for tissue engineering purposes, since the ideal matrix depends on the desired tissue. Silk biomaterials have come to focus due to their great mechanical properties. As untreated silkworm silk has been found to be quite immunogenic, an alternative could be spider silk. Not only does it own unique mechanical properties, its biocompatibility has been shown already in vivo. In our study, we used native spider dragline silk which is known as the strongest fibre in nature. Methodology/Principal Findings: Steel frames were originally designed and manufactured and woven with spider silk, harvesting dragline silk directly out of the animal. After sterilization, scaffolds were seeded with fibroblasts to analyse cell proliferation and adhesion. Analysis of cell morphology and actin filament alignment clearly revealed adherence. Proliferation was measured by cell count as well as determination of relative fluorescence each after 1, 2, 3, and 5 days. Cell counts for native spider silk were also compared with those for trypsin-digested spider silk. Spider silk specimens displayed less proliferation than collagen-and fibronectin-coated cover slips, enzymatic treatment reduced adhesion and proliferation rates tendentially though not significantly. Nevertheless, proliferation could be proven with high significance (p<0.01). Conclusion/Significance: Native spider silk does not require any modification to its application as a biomaterial that can rival any artificial material in terms of cell growth promoting properties. We could show adhesion mechanics on intracellular level. Additionally, proliferation kinetics were higher than in enzymatically digested controls, indicating that spider silk does not require modification. Recent findings concerning reduction of cell proliferation after exposure could not be met. As biotechnological production of the hierarchical composition of native spider silk fibres is still a challenge, our study has a pioneer role in researching cellular mechanics on native spider silk fibres.
