RO-Manager:A Tool for Creating and Manipulating Research Objects to Support Reproducibility and Reuse in Sciences
No full textIn this position paper we present a lightweight command-line tool RO Manager, which provides a straightforward way for scientists to assemble an aggregation of their experiment materials and methods which can then be published and shared with colleagues or linked to scientific publications, to enhance the reproducibility and trustworthiness of experiment results. The tool is currently being tested by a small group of scientists from two different domains, who would like to preserve sufficient materials and information along with their scientific results in order to improve their reproducibility in the future

Scientific Lenses over Linked Data:An approach to support task specific views of the data. A vision.
No full textWithin complex scientific domains such as pharmacology, operational equivalence between two concepts is often context-, user- and task-specific. Existing Linked Data integration procedures and equiva- lence services do not take the context and task of the user into account. We present a vision for enabling users to control the notion of opera- tional equivalence by applying scientific lenses over Linked Data. The scientific lenses vary the links that are activated between the datasets which affects the data returned to the user
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
Linked Humanities Data: The Next Frontier? A Case-study in Historical Census Data
No full textThis paper discusses the use of Linked Data to harmonize the Dutch censuses (1795-1971). Due to the long period they cover, census data is notoriously difficult to compare, aggregate and query in a uniform fashion. In social history, harmonization is the (manual) process of restructuring, interpreting and correcting original data sources to make a comparison possible. We describe a harmonization methodology based on standard Linked Data principles, illustrate how the size and complexity of the resulting linked data source poses new challenges for Semantic Web technology, and discuss potential solutions
A pilot “big data” education module curriculum for engineering graduate education: Development and implementation
No full textProjects in engineering higher education increasingly produce data in the volume, variety, velocity, and need for veracity such that the output of the research is considered “Big Data”. While engineering faculty members do conceive of and direct the research producing this data, there may be gaps in faculty members’ knowledge in training graduate and undergraduate research assistants in the practical management of Big Data. The project described in this research paper details the development of a Big Data education module for graduate researchers in Electrical and Computer Engineering. The project has the following objectives: to document and describe current data management practices within a specific research group; to identify gaps in knowledge that need to be addressed in order for research assistants to successfully manage Big Data; and to create curricular interventions to address these gaps. This paper details the motivation, relevant literature, research methodology, curricular intervention, and pilot presentation of the Big Data module. Results indicate that the fundamental concepts governing the management of Big Data have been cursorily covered in previous coursework and that students are in need of a comprehensive introduction to the topic, contextualized to the work that they are performing in the research or classroom environment
ExoMol line lists - III. An improved hot rotation-vibration line list for HCN and HNC
No full textA revised rotation-vibration line list for the combined hydrogen cyanide (HCN)/hydrogen isocyanide (HNC) system is presented. The line list uses ab initio transition intensities calculated previously and extensive data sets of recently measured experimental energy levels. The resulting line list has significantly more accurate wavelengths than previous ones for these systems. An improved value for the separation between HCN and HNC is adopted, leading to an approximately 25 per cent lower predicted thermal population of HNC as a function of temperature in the key 2000 to 3000 K region. Temperature-dependent partition functions and equilibrium constants are presented. The line lists are validated by comparison with laboratory spectra and are presented in full as supplementary data to the article and at www.exomol.com
The IPHAS catalogue of H alpha emission-line sources in the northern Galactic plane
No full textWe present a catalogue of point-source H alpha emission-line objects selected from the INT/WFC Photometric Ha Survey (IPHAS) of the northern Galactic plane. The catalogue covers the magnitude range 13 <= r' <= 19.5 and includes Northern hemisphere sources in the Galactic latitude range -5 degrees < b < 5 degrees. It is derived from similar to 1500 deg(2) worth of imaging data, which represents 80 per cent of the final IPHAS survey area. The electronic version of the catalogue will be updated once the full survey data become available. In total, the present catalogue contains 4853 point sources that exhibit strong photometric evidence for Ha emission. We have so far analysed spectra for similar to 300 of these sources, confirming more than 95 per cent of them as genuine emission-line stars. A wide range of stellar populations are represented in the catalogue, including early-type emission-line stars, active late-type stars, interacting binaries, young stellar objects and compact nebulae.
The spatial distribution of catalogue objects shows overdensities near sites of recent or current star formation, as well as possible evidence for the warp of the Galactic plane. Photometrically, the incidence of Ha emission is bimodally distributed in (r' - i'). The blue peak is made up mostly of early-type emission-line stars, whereas the red peak may signal an increasing contribution from other objects, such as young/active low-mass stars. We have cross-matched our H alpha-excess catalogue against the emission-line star catalogue of Kohoutek & Wehmeyer, as well as against sources in SIMBAD. We find that fewer than 10 per cent of our sources can be matched to known objects of any type. Thus IPHAS is uncovering an order of magnitude more faint (r' > 13) emission-line objects than were previously known in the Milky Way
