NSSDC provides network access to key data via NDADS
The National Space Science Data Center (NSSDC) is making a growing fraction of its most customer-desirable data electronically accessible via both the local and wide area networks. NSSDC is witnessing a great increase in its data dissemination owing to this network accessibility. To provide its customers the best data accessibility, the NSSDC makes data available from a nearline, mass storage system, the NSSDC Data Archive and Dissemination Service (NDADS). The NDADS, the initial version was made available in January 1992, is a customized system of hardware and software that provides users access to the nearline data via ANONYMOUS FTP, an e-mail interface (ARMS), and a C-based software library. In January 1992, the NDADS registered 416 requests for 1,957 files. By December of 1994, NDADS had been populated with 800 gigabytes of electronically accessible data and had registered 1458 requests for 20,887 files. In this report we describe the NDADS system, both hardware and software. Later in the report, we discuss some of the lessons that were learned as a result of operating NDADS, particularly in the area of ingest and dissemination

e-Commerce: How the times have changed
The advent cf E-Commerce and the information age are catalyzing fundamental decision making processes as well as their management. In this article the authors develop a functional definition of information which forms the resource base in evolving decision making activities where uncertainty and short time horizons tend to predominate. The article also makes the case that modem managers will need to be entrepreneurial

The challenges encountered with developing a valid and reliable urinary continence assessment form
The purpose of this study was to develop and validate a concise continence assessment form that can be completed by patients.A prospective, descriptive, multi-site study was conducted at three major teaching hospitals over a 6 month period utilising a repeated measure design. The study was conducted over two stages: Stage Oneconsisted of developing the face validity and user friendliness of the instrument; Stage Two consisted of establishing the test-retest reliability of the instrument.This paper discusses the process and results of the instrument development project. It highlights the clinical and statistical difficulties experienced in the development of the continence assessment form.<br /
A risk stratification tool to assess commecial influences on continuing medical education
Introduction: Heightened concerns about industry influence on continuing medical education (CME) have prompted tighter controls on the management of commercial funding and conflict of interest. As a result, CME providers must closely monitor their activities and intervene if bias or noncompliance with accreditation standards is likely. Potential for industry influence can be difficult to assess at a stage in the planning process when mitigation strategies can assure balance and content validity. Few tools exist to aid providers in this regard.
Methods: A 12-item instrument was designed to assess risk for commercial influence on CME. To determine reliability and validity, a cohort of experienced CME professionals applied the tool to standardized cases representing CME activities in the early stages of planning. Results were compared with the experts\u27 assignment of the same cases to one of four risk categories. A survey of study participants was conducted to ascertain usefulness and potential applications of the tool.
Results: Analysis demonstrated strong intraclass correlation across cases (0.90), interrater reliability (94%), and correlation between assessment of risk with and without the tool (Spearman coefficient, 0.93, p \u3c 0.01; weighted kappa, 0.59). Participants found the tool easy to use and of potential benefit to their CME office.
Discussion: The Consortium for Academic Continuing Medical Education (CACME) risk stratification tool can help CME providers identify activities that must be closely monitored for potential industry influence, remain aware of factors that place programming at risk for noncompliance with accreditation standards, and substantiate the allocation of resources by the CME office
Siphon-Controlled Automation on a Lab-on-a-Disc Using Event-Triggered Dissolvable Film Valves
Within microfluidic technologies, the centrifugal microfluidic "Lab-on-a-Disc" (LoaD) platform offers great potential for use at the PoC and in low-resource settings due to its robustness and the ability to port and miniaturize \u27wet bench\u27 laboratory protocols. We present the combination of \u27event-triggered dissolvable film valves\u27 with a centrifugo-pneumatic siphon structure to enable control and timing, through changes in disc spin-speed, of the release and incubations of eight samples/reagents/wash buffers. Based on these microfluidic techniques, we integrated and automated a chemiluminescent immunoassay for detection of the CVD risk factor marker C-reactive protein displaying a limit of detection (LOD) of 44.87 ng mL and limit of quantitation (LoQ) of 135.87 ng mL
Flavour in supersymmetry: horizontal symmetries or wave function renormalisation
We compare theoretical and experimental predictions of two main classes of
models addressing fermion mass hierarchies and flavour changing neutral
currents (FCNC) effects in supersymmetry: Froggatt-Nielsen (FN) U(1) gauged
flavour models and Nelson-Strassler/extra dimensional models with hierarchical
wave functions for the families. We show that whereas the two lead to identical
predictions in the fermion mass matrices, the second class generates a stronger
suppression of FCNC effects. We prove that, whereas at first sight the FN setup
is more constrained due to anomaly cancelation conditions, imposing unification
of gauge couplings in the second setup generates conditions which precisely
match the mixed anomaly constraints in the FN setup. Finally, we provide an
economical extra dimensional realisation of the hierarchical wave functions
scenario in which the leptonic FCNC can be efficiently suppressed due to the
strong coupling (CFT) origin of the electron mass.Comment: 23 page
Standards for Libraries in Higher Education
The Standards for Libraries in Higher Education are designed to guide academic libraries in advancing and sustaining their role as partners in educating students, achieving their institutionsâ missions, and positioning libraries as leaders in assessment and continuous improvement on their campuses. Libraries must demonstrate their value and document their contributions to overall institutional effectiveness and be prepared to address changes in higher education. These Standards were developed through study and consideration of new and emerging issues and trends in libraries, higher education, and accrediting practices. These Standards differ from previous versions by articulating expectations for library contributions to institutional effectiveness. These Standards differ structurally by providing a comprehensive framework using an outcomes-based approach, with evidence collected in ways most appropriate for each institution
