Intrasensory interference during visual working memory (WM) maintenance by object stimuli (such as faces and scenes), has been shown to negatively impact WM performance, with greater detrimental impacts of interference observed in aging. Here we assessed age-related impacts by intrasensory WM interference from lower-level stimulus features such as visual and auditory motion stimuli. We consiste...

The minimal cognitive operation of thinking of a just-seen stimulus (refreshing) was studied in 24 patients with schizophrenia and 24 normal controls. Verbal response times were measured when participants read a word, read a word immediately again, or refreshed a word just after it was no longer present. Patients showed equal priming as controls in reading a word for the second time and were sl...

Issues of digital preservation have caught attention of the Digital Libraries community in recent years, not in the least because of the work of the Task Force on Archiving of Digital Information.[2] However, concerns in the archives and records management communities about electronic record have been quite different from those expressed by the library and preservation communities. This diverge...

Knowledge on long-term preservation of micro-organisms is limited and research in the field is scarce despite its importance for microbial biodiversity and biotechnological innovation. Preservation of fastidious organisms such as methane-oxidizing bacteria (MOB) has proven difficult. Most MOB do not survive lyophilization and only some can be cryopreserved successfully for short periods. A larg...

Digital resources and documents have become part of our culture as many cultural and intellectual goods are “born-digital” – existing only in digital form. Therefore digital long-term preservation is sustaining our cultural heritage for the future. Because of its importance digital preservation is addressed by several national and international projects like the German NESTOR project [12], the ...

Maintaining and preserving fungal cultures are essential elements of systematics and biodiversity studies. Because fungi are such a diverse group, several methods of cultivation and preservation are required to ensure the viability and morphological, physiological, and genetic integrity of the cultures over time. The cost and convenience of each method, however, also must be considered. We enco...

The Chronopolis Digital Preservation Initiative, one of the Library of Congress’ latest efforts to collect and preserve at-risk digital information, has completed its first year of service as a multimember partnership to meet the archival needs of a wide range of domains. Chronopolis is a digital preservation data grid framework developed by the San Diego Supercomputer Center (SDSC) at UC San D...

Provenance description is necessary for long-term preservation of digital resources. Open Archival Information System (OAIS) and Preservation Metadata: Implementation Strategies (PREMIS), which are well-known standards designed for digital preservation, define descriptive elements for digital preservation. Metadata has to be preserved as well as primary resource in order to keep the primary res...
