This bibliography lists 133 reports, articles and other documents introduced into the NASA Scientific and Technical Information System during September 1990. Subject coverage includes: aerospace medicine and psychology, life support systems and controlled environments, safety equipment, exobiology and extraterrestrial life, and flight crew behavior and performance

Evolutionary Subject Tagging in the Humanities; Supporting Discovery and Examination in Digital Cultural Landscapes

In this paper, the authors attempt to identify problematic issues for subject tagging in the humanities, particularly those associated with information objects in digital formats. In the third major section, the authors identify a number of assumptions that lie behind the current practice of subject classification that we think should be challenged. We move then to propose features of classification systems that could increase their effectiveness. These emerged as recurrent themes in many of the conversations with scholars, consultants, and colleagues. Finally, we suggest next steps that we believe will help scholars and librarians develop better subject classification systems to support research in the humanities.NEH Office of Digital Humanities: Digital Humanities Start-Up Grant (HD-51166-10

A principal component analysis of 39 scientific impact measures

The impact of scientific publications has traditionally been expressed in terms of citation counts. However, scientific activity has moved online over the past decade. To better capture scientific impact in the digital era, a variety of new impact measures has been proposed on the basis of social network analysis and usage log data. Here we investigate how these new measures relate to each other, and how accurately and completely they express scientific impact. We performed a principal component analysis of the rankings produced by 39 existing and proposed measures of scholarly impact that were calculated on the basis of both citation and usage log data. Our results indicate that the notion of scientific impact is a multi-dimensional construct that can not be adequately measured by any single indicator, although some measures are more suitable than others. The commonly used citation Impact Factor is not positioned at the core of this construct, but at its periphery, and should thus be used with caution

A Review of Trip Planning Systems.

This report reviews current information provision in all modes of transport and assesses the needs for and benefits of trip planning systems. The feasibility of trip planning systems is discussed given the current state of technology and information availability and supply. The review was stimulated by technological developments in telecommunications and information technology which are providing the possibility of a greatly enhanced quality of information to aid trip planning decisions. Amongst the conclusions reached were the following: Current information provision is considered deficient in many respects. Travellers are often unaware of alternative routes or services and many are unable to acquire adequate information from one source especially for multi-modal journeys. In addition, there is a lack of providing real time information where it is required (bus stops and train stations) and of effective interaction of static and real time information. Most of the projects, which integrate static and dynamic data, are single mode systems. Therefore there is a need for an integrated trip planning system which can inform and guide on all aspects of transport. Trip planning systems can provide assistance in trip planning (before and during the journey) using one or a number of modes of travel, taking into account travellers preferences and constraints, and effectively integrating static and dynamic data. Trip planning systems could adversely affect traffic demand as people who become aware of new opportunities might be encouraged to make more journeys. It could also affect travellers choice as a result of over-saturation of information, over-reaction to predictive information, and concentration on the same 'best' routes. However, it can be argued, based on existing evidence, that such a system can benefit travellers, and transport operators as well as the public sector responsible for executing transport policies. Travellers can benefit by obtaining adequate information to help them in making optimal decisions and reducing uncertainty and stress associated with travel. Public transport operators can benefit by making their services known to customers, leading to increased patronage. Public transport authorities can use the supply of information to execute their transport policies and exercise more control over traffic management

Outlines the themes and contributions of the Free Culture and the Digital Library Symposium.The article provides a summary of the conflict of interests between those who seek to preserve ashared commons of information for society and those who seek to commodify information. Iintroduce a theoretical framework called Transmediation to help explain the changes in mediathat society is currently experiencing

Foucault in Cyberspace: Surveillance, Sovereignty, and Hardwired Censors

This is an essay about law in cyberspace. I focus on three interdependent phenomena: a set of political and legal assumptions that I call the jurisprudence of digital libertarianism, a separate but related set of beliefs about the state\u27s supposed inability to regulate the Internet, and a preference for technological solutions to hard legal issues on-line. I make the familiar criticism that digital libertarianism is inadequate because of its blindness towards the effects of private power, and the less familiar claim that digital libertarianism is also surprisingly blind to the state\u27s own power in cyberspace. In fact, I argue that the conceptual structure and jurisprudential assumptions of digital libertarianism lead its practitioners to ignore the ways in which the state can often use privatized enforcement and state-backed technologies to evade some of the supposed practical (and constitutional) restraints on the exercise of legal power over the Net. Finally, I argue that technological solutions which provide the keys to the first two phenomena are neither as neutral nor as benign as they are currently perceived to be. Some of my illustrations will come from the current Administration proposals for Internet copyright regulation, others from the Communications Decency Act and the cryptography debate. In the process, I make opportunistic and unsystematic use of the late Michel Foucault\u27s work to criticise some the jurisprudential orthodoxy of the Net

Digital Image Access & Retrieval

The 33th Annual Clinic on Library Applications of Data Processing, held at the University of Illinois at Urbana-Champaign in March of 1996, addressed the theme of "Digital Image Access & Retrieval." The papers from this conference cover a wide range of topics concerning digital imaging technology for visual resource collections. Papers covered three general areas: (1) systems, planning, and implementation; (2) automatic and semi-automatic indexing; and (3) preservation with the bulk of the conference focusing on indexing and retrieval.published or submitted for publicatio

Moving Knowledge – Touch the Clouds

A resilient industrial ‘grammar of schooling’ is challenged by technological disruption. On a backdrop of commodification and globalization this thrust is marked by the rapid uptake of multi-touch access devices within wireless client-server architectures. Based on two sets of empirical data and personal observations this paper abductively suggests that we may think of this in terms of the increased importance of (i) intellectual commonplaces, (ii) attention streams and (iii) body languages. In this paradigm the educational institution should be careful not to become a pure operator of extrinsic certification
