    A summary of the active flexible wing program

    Get PDF
    A summary of the NASA/Rockwell Active Flexible Wing Program is presented. Major elements of the program are presented. Key program accomplishments included single- and multiple-mode flutter suppression, load alleviation and load control during rapid roll maneuvers, and multi-input/multi-output multiple-function active controls tests above the open-loop flutter boundary

    A Group’s a Group, No Matter How Small: An Economic Analysis of Defamation

    Consider the following: A Jews-for-Jesus bulletin reports, falsely, that a Jewish woman became “a believer in the tenets, the actions, and the philosophy of Jews for Jesus.” Does this publication constitute defamation? Should defamatoriness be determined in accordance with the views of the general non- Jewish community, with those of the Jewish minority, or with a normative ethical commitment? Our Article aims to provide the answers. Part I demonstrates that the de finition of defamatoriness in common law jurisdictions is essentially empirical and distinguishes between the two leading tests—the English test and the American test. Part II.A describes the English, or general community test, whereby a statemen t is defamatory if considered so by the “right thinking members of the public at large.” Part II.B details the American, or sectorial test, whereby a statement is defamatory if considered so by a substantial and respectable minority. A third possible empirical test, whereby the defamatory potential of a statement may be tested within a small group, has not been adopted in any jurisdiction. Part III, however, demonstrates that the small group test is an economically preferable option to both the English and American tests. Part III conducts two separate economic analyses of the alternative empirical tests for defamation. First, we study the relationship between the view of the community and the views of the individuals who comprise the community. We show that the defamation cases should be decided according to the unanimity rule: A statement may be conside red defamatory only when all individuals in the relevant community consider it so. Because this rule is implausible except in the case of the small group test, it suggests that both the English and American tests lack a solid theoretical foundation. Second, we study the costs and benefits associated with the various tests and find that the American sectorial test is no longer optimal. As a result, we argue that it is preferable to adopt the small group test when deciding cases of defamation

    Understanding Why Older Adults With Type 2 Diabetes Join Diabetes Online Communities: Semantic Network Analyses.

    BackgroundAs individuals age, chronic health difficulties may disrupt physical and social well-being. Individuals can turn to online communities to interact with similar peers, which may help buffer negative effects resulting from health difficulties.ObjectiveThis study investigated the reasons that older adults join a diabetes online community to better understand the specific resources that are being sought.MethodsWe used semantic network analyses to categorize the reasons participants provided for joining a community during the sign-up process.ResultsThe most frequent reasons for joining were to seek information about their health condition, to help with self-management of health difficulties, for feelings of informational and social support, and for having a community with whom to share. Women were more likely to go online for sharing and companionship as well as for information and social support reasons, whereas men were more likely to go online for general information and self-management reasons.ConclusionsThis study shows the reasons older adults seek to join a diabetes online community: for increased information and support regarding chronic health difficulties. Practitioners may want to consider ways to promote access to online communities among their older patients as a source of health information and a resource to provide a sense of community

    Issues in the Design of a Pilot Concept-Based Query Interface for the Neuroinformatics Information Framework

    Get PDF
    This paper describes a pilot query interface that has been constructed to help us explore a "concept-based" approach for searching the Neuroscience Information Framework (NIF). The query interface is concept-based in the sense that the search terms submitted through the interface are selected from a standardized vocabulary of terms (concepts) that are structured in the form of an ontology. The NIF contains three primary resources: the NIF Resource Registry, the NIF Document Archive, and the NIF Database Mediator. These NIF resources are very different in their nature and therefore pose challenges when designing a single interface from which searches can be automatically launched against all three resources simultaneously. The paper first discusses briefly several background issues involving the use of standardized biomedical vocabularies in biomedical information retrieval, and then presents a detailed example that illustrates how the pilot concept-based query interface operates. The paper concludes by discussing certain lessons learned in the development of the current version of the interface

    The NIF LinkOut Broker: A Web Resource to Facilitate Federated Data Integration using NCBI Identifiers

    Get PDF
    This paper describes the NIF LinkOut Broker (NLB) that has been built as part of the Neuroscience Information Framework (NIF) project. The NLB is designed to coordinate the assembly of links to neuroscience information items (e.g., experimental data, knowledge bases, and software tools) that are (1) accessible via the Web, and (2) related to entries in the National Center for Biotechnology Information’s (NCBI’s) Entrez system. The NLB collects these links from each resource and passes them to the NCBI which incorporates them into its Entrez LinkOut service. In this way, an Entrez user looking at a specific Entrez entry can LinkOut directly to related neuroscience information. The information stored in the NLB can also be utilized in other ways. A second approach, which is operational on a pilot basis, is for the NLB Web server to create dynamically its own Web page of LinkOut links for each NCBI identifier in the NLB database. This approach can allow other resources (in addition to the NCBI Entrez) to LinkOut to related neuroscience information. The paper describes the current NLB system and discusses certain design issues that arose during its implementation
