    The NASA/IPAC Infrared Science Archive (IRSA) curates and serves science data sets from NASA’s infrared and submillimeter projects and missions, including IRAS, 2MASS, MSX, SWAS, ISO, IRTS and from the Spitzer Space Telescope. All Spitzer data can be accessed from IRSA’s Spitzer mission page at: http://irsa.ipac.caltech.edu/Missions/spitzer.html Spitzer Legacy Enhanced Products along with ancillary data are delivered in six month intervals starting from Fall 2004, until Fall 2006. IRSA continually ingests the Spitzer data and the ancillary data, and these data are made accessible through IRSA’s query engines. Legacy products for the C2D, FEPS, GLIMPSE, GOODS, SINGS and SWIRE projects are accessible through a common interface http://irsa.ipac.caltech.edu/applications/Atlas. This engine returns the spatial footprints of observations and provides access to all flavors of released data sets, including, where appropriate, previews of image mosaics, 3-color image mosaics and spectra

    A New Approach to Tagging Data in the Astronomical Literature

    Data Tags are strings used in journals to indicate the origin of the archival data and to enable the reader to recover the data. The NASA/IPAC Infrared Science Archive (IRSA) has recently introduced a new approach to production of data tags and recovery of data from them. Many of the data access services at the IRSA return filtered data sets (such as subsets of source catalogs) and dynamically created products (such as image cutouts); these dynamically created products are not saved permanently at the archive. Rather than tag the data sets from which the query result sets are drawn, the archive tags the query that generates the results. A single tag can, then, encode a complex dynamic data set and simplifies the embedding of tags in manuscripts and journals. By logging user queries and all the parameters for those query as Data Tags, IRSA can re-create the query and rerun the IRSA service using the same search parameters used when the Data Tag was created. At the same time, the logs give a simple count of the actual numbers of queries made to the archive, a powerful metric of archive usage unobtainable from the Apache web server logs. Currently, IRSA creates tags for queries to more than 20 data sets, including the Infrared Astronomical Satellite (IRAS), Cosmic Evolution Survey (COSMOS) and Spitzer Space Telescope Legacy Data Sets. These tags are returned by the spatial query engine, Atlas. IRSA plans to create tags for queries to the rest of its services in late Spring 2007. The archive provides a simple web interface which recovers a data set that corresponds to the input data tag. Archived data sets may evolve in time due to improved calibrations or augmentations to the data set. IRSA’s query based approach guarantees that users always receive the best available data sets

    Studi Empiris Atas Kualitas Audit

    This study aims to determine whether the competence, independence, time budget pressure, and ethicalimpact on audit quality. Research with the theme of quality audit becomes important in two points: first,as a way of seeing reality in compliance auditor to audit standards and the second, while maintaining usertrust. Audit quality on the one hand can increase the reliability of the information, on the other hand isinfluenced by many factors such as the competence, independence, time budget pressure, and ethics. Thisstudy uses the KAP auditor as respondents, by considering two important things: first, in Jakarta and thesecond, the category of non big four, as a way of presenting variation among the existing research. Totalrespondents 106 auditors were selected purposively and proportionally from 17 KAP. The data isprocessed using multiple linear regressions after classical assumption test and instrument questionnairetest. The results showed all four of the above factors have a significant effect on audit quality.Suggestions of this study extend some aspects of the research

    Jeremy Bentham\u27s Panopticon Design in Practise [sic] Within the City of Perth

    Get PDF
    This thesis outlines an investigation of Jeremy Bentham’s Panopticon Design that identifies the mechanisms of power which are found to be inherent characteristics within new surveillance technologies. The study includes a discussion of the Perth City Council\u27s implementation of the surveillance program in October 1991 including a detailed analysis of the cultural centre public space. Material provided by Gerard Martinet from the City of Perth, and the Security Industry helped establish a factual ground to form the basis of the investigation. I have sourced a number of academic texts from university libraries, particularly Murdoch University, Curtin University and The University of Western Australia. These texts have offered a broad reading and position from which to start the theoretical framework. I explore Foucault\u27s post structuralist texts by qualitative methodology and comparative analysis, drawing discussion to new surveillance technologies and their impact and use within the City of Perth. A discussion on the decline of the city gave reference to Stanley Cohen for an assessment of the state of society and the current justifications for surveillance technologies. I then identify artists who show how it is appropriate for them to produce work that deals with socio-political concerns and issues that function as social commentary

    The House of Kadmos at Mycenaean Thebes: A preliminary re-examination of the architecture

    Get PDF
    During 1906-1929 Antonios Keramopoullos unearthed the surviving portion of a massive Mycenaean building at Thebes, Greece, the so-called "House of Kadmos". In 1971, and possibly in 1964, more parts of this building came to light south of Keramopoullos' excavations. This research does not claim to be an integrated analysis of the building in terms of "form, function and chronology", but is a preliminary study of its architectural remains. The thesis focuses on the schematic reconstruction of the landscape upon which the building stands, the description of the surviving remains, the analysis of building materials and construction techniques. The prominent location of the edifice and some of its construction characteristics (e.g. the pseudo-ashlar wall, a possible light-well, the multi-storeyed elevation) would seem to fit the standards of Mycenaean palatial architecture. However, whether the "House of Kadmos" is the central core of a palace or an (ancillary?) palatial structure is unclear, although the terrace type employed suggests that it was a free-standing building. The surviving portion of the plan reveals that it was predetermined and that it belongs to a purely Helladic architectural tradition, already crystallised in Menelaion Mansion I. A summary of the excavation campaigns and recorded clean-up operations, as well as general discussions on the plan and the elevation of the building are included (Volume I). A new plan, sections and other original drawings accompany the dissertation (Volume II). The plan and sections are based on the results of two fieldwork campaigns at the "House of Kadmos" (April and July 1998)

    Condotte compulsive in paziente con sindrome di Aicardi. agenesia del corpo calloso

    Get PDF
    The corpus callosum, which is the largest white matter structure in the brain of all placental mammals, connects the left and right cerebral hemispheres. An alteration in its morphology, hypoconnectivity or hyperconnectivity is a common marker of various neuropsychiatric pathologies. One of these is Aicardi syndrome, which is characterized by a triad of callosal agenesis, infantile spasms and chorioretinal lacunae. Patients affected by Aicardi syndrome frequently display other malformations together with congenital defects of the eyes, ribs and vertebrae. Based on the current clinical knowledge, this syndrome is now recognized as a complex neurodevelopmental disorder that includes neurological and constitutional symptoms. However, literature data have not yet defined the presence of a particular set of symptoms in psychiatric patients with this condition. The present case is the first report in which an on-going compulsive behaviour focused on the insistence to order objects has been observed in Aicardi syndrom
