description: The Australian Social Science Data Archive (ASSDA) faces interesting challenges in acquiring and distributing social science data to a relatively small but widely dispersed - in geographic terms - research community. This presentation will examine how new technologies can assist in transforming an archive that has primarily functioned in a highly centralised manner to a distributed archive that operates nodes in major cities around Australia. The first part of the paper will concentrate on the institutional and management issues that arise fom such a change. The second part of the paper will address a range of technical challenges, including: the provision of a seamless access interface to holdings for users; maintenance of consistent archiving pratices at each node; and describe a software program (APS) developed by ASSDA staff to achieve a common standard.

description: We present static and dynamical properties of linear vortices in 4He droplets obtained from Density Functional calculations. By comparing the adsorption properties of different atomic impurities embedded in pure droplets and in droplets where a quantized vortex has been created, we suggest that Ca atoms should be the dopant of choice to detect vortices by means of spectroscopic experiments.

description: The quest for binary and dual supermassive black holes (SMBHs) at the dawn of the multi-messenger era is compelling. Detecting dual active galactic nuclei (AGN) -- active SMBHs at projected separations larger than several parsecs -- and binary AGN -- probing the scale where SMBHs are bound in a Keplerian binary -- is an observational challenge. The study of AGN pairs (either dual or binary) also represents an overarching theoretical problem in cosmology and astrophysics. The AGN triggering calls for detailed knowledge of the hydrodynamical conditions of gas in the imminent surroundings of the SMBHs and, at the same time, their duality calls for detailed knowledge on how galaxies assemble through major and minor mergers and grow fed by matter along the filaments of the cosmic web. This review describes the techniques used across the electromagnetic spectrum to detect dual and binary AGN candidates and proposes new avenues for their search. The current observational status is compared with the state-of-the-art numerical simulations and models for formation of dual and binary AGN. Binary SMBHs are among the loudest sources of gravitational waves (GWs) in the Universe. The search for a background of GWs at nHz frequencies from inspiralling SMBHs at low redshifts, and the direct detection of signals from their coalescence by the Laser Interferometer Space Antenna in the next decade, make this a theme of major interest for multi-messenger astrophysics. This review discusses the future facilities and observational strategies that are likely to significantly advance this fascinating field.

On the human inability to process inverse variables in intuitive judgments: Different cognitive processes leading to a time loss bias

description:
 We investigated the time loss bias: overestimation of time lost after a speed decrease from high speeds and underestimations after decrease from low driving speeds. The bias depends to a great extent on the human inability to use correctly inverse variables in intuitive judgments. Participants judged the speed decrease from one speed (e.g., 130 kmph) that would give the same time loss as a decrease from another speed (e.g., from 40 to 30 kmph). We carried out descriptive spectral analyses of distributions of judgments for each problem. Each distribution peak was associated with a judgment rule. The first study found two different judgment processes both leading to the time loss bias: a Difference process rule used for 20% and a Ratio rule used for 31% of the judgments. The correct rule applied to 10% of the judgments. The second study replicated the first study and added verbal protocols. The results showed that the Ratio rule was most common (41%) followed by the Difference (12%) and correct (8%) rules. Verbal reports supported these results.

Strengths and weaknesses of the DDI Aggregate Data Extension in directly driving an on-line data visualisation system
Creators: name: Southall, Humphrey
Publisher: name: Zenodo
Year: 2005

description: The "Vision of Britain through Time" website, UK National Lottery-funded, presented at IASSIST 2004 and launched last October, makes diverse historical information on Britain's localities available to the general public, but most of its contents are statistical: currently, 10.6m distinct data values. This paper focuses on our implementation of the DDI Aggregate Data Extension, fundamental to the system's internal operation: data are all held in one column of one database table and must be assigned to an nCube to be mapped or graphed. Some extensions reflect the particular application: the definition of themes and rates as additional entities. Others may be of more general applicability: defining universes and measurement units as entities, not attributes. Holding data in Oracle means the data map holds "cell references", not physical locations. Our metadata has to organise data from multiple censuses to chart change over time, making metadata authoring an act of interpretation.

description: Technology is increasingly altering the world’s natural landscapes in permanent and often irreparable ways. The shift towards more efficient, and productive modes of producing food for example, has changed both our relationship with, and understanding of our landscapes and the products we consume. As we progressively remove ourselves from the production process of the things we consume, the environments we choose to or are compelled to live in, are becoming increasingly abstract. In addition, there is a perpetual need to produce more food to help tackle global challenges such as the global food crisis by providing alternative, more efficient ways to not only produce, but also consume food. While well-intended and certainly ambitious, such growing procedures often fail to address the social, cultural and spiritual importance of food, as well as the resultant landscapes created. Thus the goal of the project is two fold: First, it seeks to explore what happens to existing landscapes and people once technologies replaced both; secondly, the project investigates how food is not only a biological necessity, a product valued only for its end use, but rather one that has built and shaped cultures, landscapes, and the essential understanding of life.

description: A detailed comparison is presented of the temperature dependence of the conductivity of dilute, strongly interacting electrons in two-dimensional silicon inversion layers in the metallic regime in the presence and in the absence of a magnetic field. We show explicitly and quantitatively that a magnetic field applied parallel to the plane of the electrons reduces the slope of the conductivity versus temperature curves to near zero over a broad range of electron densities extending from $n_c$ to deep in the metallic regime where the high field conductivity is on the order of $10 e^2/h$. The strong suppression (or "quenching") of the metallic behavior by a magnetic field sets an important constraint on theory.

description: Young stars are surrounded by a circumstellar disk of gas and dust, within which planet formation can occur. Gravitational forces in multiple star systems can disrupt the disk. Theoretical models predict that if the disk is misaligned with the orbital plane of the stars, the disk should warp and break into precessing rings, a phenomenon known as disk tearing. We present observations of the triple star system GWOrionis, finding evidence for disk tearing. Our images show an eccentric ring that is misaligned with the orbital planes and the outer disk. The ring casts shadows on a strongly warped intermediate region of the disk. If planets can form within the warped disk, disk tearing could provide a mechanism for forming wide-separation planets on oblique orbits.

On supersymmetric solutions of type IIB supergravity with general fluxes

description: We propose a general spinor Ansatz to find supersymmetric configurations preserving 4-dimensional Poincare' invariance in the context of type IIB supergravity in the presence of general fluxes. We show how this removes the imaginary-selfduality (ISD) constraint on the 3-form flux and present a simple example with nonvanishing (0,3) flux. To characterize the geometrical properties of such configurations we will use the tool of SU(2) structures on the internal space, which are naturally linked to the form of the Ansatz we propose.

The integrated photo-documentary online database
Creators: name: Zoltan Lux
Publisher: name: Zenodo
Year: 2005

description: The photo-documentary database forms part of the contemporary history database at the 1956 Institute. It began to be compiled in 1997 after the Institute won competitive research and development funding from the Hungarian state. There is a constant need for photographic illustrations for the Institute's printed and digital publications. Initially, digital photos were simply archived on cd-rom, with attached text files containing descriptions of them. Once a large number of photos connected with post-Second World War Hungarian history had accumulated, it was seen that storage in a database would facilitate repeated use of them. Only the descriptions were included in the database at first, while the digitalized, high-resolution files and associated thumbnails were stored in a separate cd-rom library. The photo descriptions began to be made available on the Internet in 1998. Although the user interface operated in a rather cumbersome way, there was quite a large demand from schools, public institutions and the press, mainly on the occasion of various national commemorations. (http://www.rev.hu/foto/plsql/foto_1a_www_e$.startup) For the Oral History Project presented at the 2004 IASSIST conference, the structure of the database was transformed and integrated into the contemporary history database, so that photo documents would be incorporated in a direct and uniform way into all the Internet projects the Institute is preparing. (http://server2001.rev.hu/oha/index.html) On the structure of the photo archiving and photo database in the presentation, I would like to mention the following issues and problems: 1. Technical issues concerning digitalization of the photo documents (resolution, file format, data storage). 2. Problems relating to collection, archiving and provision of the photo documents and copyright issues. Expansion of the work of collecting photo documents. 3. Description of the photo documents in the light of international standards and recommendations. 4. A short presentation of the database (structure, how photos are linked to other documents, events, persons etc.) Making the database multilingual. Search facilities and other demands. 5. Experience at the Institute with using the database.
Next-to-Leading Order Constituent Quark Structure and Hadronic Structure Functions

description: We calculate the partonic structure of a constituent quark in the Next-to-Leading Order framework. The structure of any hadron can be obtained thereafter using a convolution method. Such a procedure is used to generate the structure function of proton and pion in NLO, neglecting certain corrections to $Λ_{QCD}$. It is shown that while the constituent quark structure is generated purely perturbatively and accounts for the most part of the hadronic structure, there is a few percent contributions coming from the nonperturbative sector in the hadronic structure. This contribution plays the key role in explaining the SU(2) symmetry breaking of the nucleon sea and the observed violation of Gottfried sum rule. These effects are calculated. We obtained an Excellent agreement with the experimental data in a wide range of $x=[10^{-6}, 1]$ and $Q^{2}=[0.5, 5000]$ $GeV^{2}$ for the proton structure function. We have also calculated Pion structure and compared it with the existing data. Again, the model calculations agree rather well with the data from experiment.

SPECIES CHARACTERISATION. — Shell turbiniform, only last whorl showing a flattened profile to the upper half, rounded periphery, bearing reddish zigzag colour pattern interrupted by two rows of white blotches the upper placed below the suture, the lower mid-whorl.
DISTRIBUTION (OF SUBSPECIES T. pullus picta). — Upper Pliocene: Atlantic, St Erth, England (Harmer 1925), Selsoif, NW France (this paper). Today it is present from the western coasts of British Isles (absent in Scandinavia and North Sea) south to Gibraltar (Fretter & Graham 1977). Further south it is replaced by the subspecies T. pullus canarica Nordsieck, 1973 in the Canary Islands & Madeira (Hernández et al. 2011). It lives in rocky pools, 0-35 m depth, common on red weeds (Fretter & Graham 1977).
REMARKS
Two subspecies occur today. Tricolia pullus pullus (Linnaeus, 1958), present in the Mediterranean to the Strait of Gibraltar, is characterised by its rounded last whorl and spotted colour pattern. The Atlantic T. pullus picta (da Costa, 1778) ranging from the British Isles to Morocco has a flattened base of the last whorl and predominantly zigzag pattern that is especially prominent on the base. The material at hand consists of a single fragment of a last whorl that agrees with the present-day Atlantic form. In their work on the Tortonian Upper Miocene of NW France, Landau et al. (2017: 153) noted that all forms occurred together in those assemblages and postulated that these subspecies may not have separated at the time. The material from Selsoif is scant, but suggest the Atlantic form had split by at least the Gelasian.

description: We study the formation of polar ring galaxies via minor mergers. We used N-body+hydrodynamics simulations to reproduce the dynamics of the observed system AM 2229-735 that is a minor merger whose interaction signals are those of a progenitor for a polar ring galaxy. We used the observational information of the system to get initial conditions for the orbit and numerical realisations of the galaxies to run the simulations. Our simulations reproduce the global characteristics of interaction observed in the system such as arms and a material bridge connecting the galaxies. As a merger remnant, we found a quasi-stable and self gravitating planar tidal stream with dark matter, stars and gas orbiting in a plane approximately perpendicular to the main galaxy disk leading in the future to a polar ring galaxy. We studied the dynamical conditions of the polar structure and found evidence suggesting that this kind of merger remnant can settle down in a disk-like structure with isothermal support, providing inspiring evidence about the process of formation of galactic disks and providing a potentially independent scenario to study the presence of dark matter in this kind of galaxies.

Upgrading ABC News/Washington Post data collections using DDI and legacy databases

description: During the past several years the Roper Center has been integrating its online question-level retrieval system (iPOLL) with its catalog of dataset holdings. While critical steps have been successfully implemented on the study and file levels, much more could be done on the variable level to fully realize the research potential of these data resources. As a step toward this end, the Roper Center is working with ABC News and the Washington Post to produce fully documented data files for many polls conducted from 1979 to 1997. The metadata and system file generation project will seek to build upon the iPOLL question-level database by extending it to better reflect elements of the Data Documentation Initiative (DDI). The resulting variable-level metadata can then be used to create DDI-based XML files, SPSS syntax and system files. This presentation will describe the scope and requirements of the project, mapping of iPOLL database fields to DDI variable elements (Section 4), and the user interface for project and metadata management. Finally, an update on progress and a review of the potential for generalized utility of the system and lessons learned will be addressed.

description: The House Report 111-181 accompanying H.R. 2997, the 2010 Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Appropriations Bill, requested the USDA’s Economic Research Service (ERS) in conjunction with the Office of the Chief Economist, to conduct a study of land-use changes for renewable fuels and feedstocks used to produce them. This report summarizes the current state of knowledge of the drivers of land-use change and describes the analytic methods used to estimate the impact of biofuel feedstock production on land use. The models used to assess policy impacts have incorporated some of the major uncertainties inherent in making projections of future conditions, but some uncertainties will continue to exist. The larger the impact of domestic biofuels feedstock production on commodity prices and the availability of exports, the larger the international land-use effects are likely to be. The amount of pressure placed on land internationally will depend in part on how much of the land needed for biofuel production is met through an expansion of agricultural land in the United States. If crop yield per acre increases through more intensive management or new crop varieties, then less land is needed to grow a particular amount of that crop.

Can classical wormholes stabilize the brane-anti-brane system?

Year: 2003
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We investigate the static solutions of Callan and Maldecena and Gibbons to lowest order Dirac-Born-Infeld theory. Among them are charged wormhole solutions connecting branes to anti-branes. It is seen that there are no such solutions when the separation between the brane and anti-brane is smaller than some minimum value. The minimum distance coincides with the energy minimum, and depends monotonically on the charge. Making the charge sufficiently large, such that the minimum separation is much bigger than $ \sqrt{α'}$, may suppress known quantum processes leading to decay of the brane-anti-brane system. For this to be possible the zeroth order wormhole solutions should be reasonable approximations of solutions in the full $D-$brane theory. With this in mind we address the question of whether the zeroth order solutions are stable under inclusion of higher order corrections to the Dirac-Born-Infeld action.

Training subject librarians to provide data services
Creators: name: McNeill-Harman, Katherine
Publisher: name: Zenodo
Year: 2005

description: Many academic data service librarians work among colleagues who specialize in particular subjects. These subject librarians are experts in their subject areas and maintain close relationships with users in their departments. Given the interdisciplinary nature of data, involving them in providing data services provides an opportunity to leverage their expertise and reach a broader base of potential users. Thus, the MIT Data Services Librarian initiated a project to train subject librarians on data services so that they could: - provide improved data reference service, - refer users to related campus resources, - improve coverage of data in their instruction sessions, and - discuss with their departmental faculty the Libraries' projects regarding data collections and services for data producers. The presenter will discuss the development and implementation of the program, plans for ongoing training, and suggestions for involving subject librarians at other universities.

description: We design a quantum repeater architecture using individual $^{167}$Er ions doped into Y$_2$SiO$_5$ crystal. This ion is a promising candidate for a repeater protocol because of its long hyperfine coherence time in addition to its ability to emit photons within the telecommunication wavelength range. To distribute entanglement over a long distance, we propose two different swapping gates between nearby ions using the exchange of virtual cavity photons and the electric dipole-dipole interaction. We analyze their expected performance, and discuss their strengths and weaknesses. Then, we show that a post-selection approach can be implemented to improve the gate fidelity of the virtual photon exchange scheme by monitoring cavity emission. Finally, we use our results for the swapping gates to estimate the end-to-end fidelity and distribution rate for the protocol.

REMARKS
Specific identity is difficult to establish due to lack of protoconch in the studied material. Here tentatively assigned to Petaloconchus intortus (Lamarck, 1818), a common species in fossil faunas from North West Europe. The modern species Petaloconchus glomeratus (Linnaeus, 1758) is similar to P.intortus except for the protoconch, absent in the specimens from Selsoif. For further discussion see Landau et al. (2018: 246).

description: Many students do not have a deep understanding of slope. This paper defines what a deep understanding of slope is in terms of mathematics-education theory. The various factors which help explain why such a deep understanding is difficult to acquire are then discussed. These factors include the following: the different representations for slope; graphical understanding; ratio and rate; and proportional reasoning. In light of this discussion, the design of a mathematical resource to help give students a deep understanding of slope is described. The resource was used at one university, amongst Chinese first-year undergraduate science and engineering students. Evidence would suggest that those students who did not evidence a correct understanding of all the aspects of slope (deep understanding) before completing the resource improved their understanding of these aspects upon completion of the resource.

description: We present deep CCD photometry in the VI passbands using the WIYN 3.5m telescope of a field located approximately 20' southeast of the center of M33; this field includes the region studied by Mould & Kristian in their 1986 paper. The color-magnitude diagram (CMD) extends to I~25 and shows a prominent red giant branch (RGB), along with significant numbers of asymptotic giant branch and young main sequence stars. The red clump of core helium burning stars is also discernable near the limit of our CMD. The I-band apparent magnitude of the red giant branch tip implies a distance modulus of (m-M)_I = 24.77 +/- 0.06, which combined with an adopted reddening of E(V-I)=0.06 +/- 0.02 yields an absolute modulus of (m-M)_0 = 24.69 +/- 0.07 (867 +/- 28 kpc) for M33. Over the range of deprojected radii covered by our field (~8.5 to ~12.5 kpc), we find a significant age gradient with an upper limit of ~1 Gyr (~0.25 Gyr/kpc). Comparison of the RGB photometry to empirical giant branch sequences for Galactic globulars allows us to use the dereddened color of these stars to construct a metallicity distribution function (MDF). The primary peak in the MDF is at a metallicity of [Fe/H] ~ -1.0 with a tail to lower abundances. The peak does show radial variation with a slope of d[Fe/H]/dR_{deproj} = -0.06 +/- 0.01 dex/kpc. This gradient is consistent with the variation seen in the inner disk regions of M33. As such, we conclude that the vast majority of stars in this field belong to the disk of M33, not the halo as previously thought.

description: In PT-symmetric gratings, asymmetric diffraction can be generated by modulating the ratio between imaginary and real refractive indices. In this paper, a rigorous coupled-wave analysis (RCWA) has been developed to analyze the diffraction properties of acoustic PT-symmetric gratings with two kinds of modulating approaches, including modulating the effective modulus and the effective density. Asymmetric diffraction with both Bragg incident angles and perpendicular incident angles is discussed by using the RCWA method. Results show that the modulation ratio for the diffraction vanishing point changes with the modulation amplitude differently for two kinds of modulating approaches. Moreover, the sound energy will be weaken or be enhanced at Bragg incident angles depending on the sign of incident angles and the modulation ratio.

description: Although extensive research has been carried out on massive open online courses (MOOCs) as representative of connectivist environment, none of them has succeeded to enlighten our understanding about the individual learning experience in connectivist environment at higher educational context. This paper taped into this crucial issue and traced the individual learning experiences of nine students at regular universities. The participants engaged into a connectivist learning environment by solving 10 tasks each and were tracked using retrospective think-aloud protocols. The patterns of similarities and differences among participants and among tasks were analyzed using qualitative data analysis, supported by visual inspection of the participants’ steps. The experimental work presented in this study provides fresh insight into the way at which students at higher education institutes perceive and experience connectivist environment.
Adventures in Menstrual World
Creators: name: Booth, Julia
Publisher: name: The University of British Columbia

description: Half the world’s population experiences menstruation during their lifetime. Menstruation plays an essential role in the human life cycle. Without it, none of us would be here today. And yet, it is stigmatized all over the world. Menstruation is seen as dirty, shameful, embarrassing, something to be hidden. These attitudes are a form of sexual discrimination that serve to limit and isolate menstruating people – and non-menstruating people. What if we lived in a world that celebrated menstruation? A world that revered its life-giving power? A world where periods were a source of pride, not shame? A world that offered greater support and comfort throughout the menstrual cycle? This thesis explores the wonderful possibilities of that world. Using a holistic approach ranging in scale from the menstrual cup to urban infrastructure systems, this project proposes different ways of making space for menstruating bodies.
REFORME ADMINISTRATIVE AU GABON :  L'ADOPTION DE LA GESTION PREVISIONNELLE DES EFFECTIFS, DES EMPLOIS ET DES COMPETENCES.

description: Cet article a pour objectif d’appréhender l’apport de la gestion prévisionnelle des effectifs, des emplois et des compétences (GPEEC) au management des ressources humaines (RH) dans un contexte administratif fortement évolutif, marqué par la réforme du secteur public au Gabon. L’analyse qualitative et exploratoire de la série d’entretiens auprès de responsables RH des départements ministériels dans cette étude montre que la GPEEC est un outil moderne de gestion des ressources humaines qui permet au gouvernement de maitriser au mieux les effectifs de la fonction publique au regard de l’analyse expérimentale qui relève que, dans les administrations publics gabonaises, sans ressources humaines de qualité, il serait difficile d’opérer les réformes nécessaires au processus de modernisation de l’Etat. C’est une vision du nouveau management public qui considère que la modernisation de l’administration publique passe nécessairement par une planification stratégique des ressources humaines. Cette tendance reflète la volonté de rechercher un ajustement des compétences aux besoins des organisations, dans le but de pérenniser l’emploi.
Introducing data history to students

description: How many times have you heard "I'm an English major or I'm a History major, I don't need to understand data!"? The use of data and its interpretation has not been exploited in today's curriculum and has resulted in many students lacking the basic know-how when it comes to data use and interpretation. At the University of Guelph, the history and economics departments offer a course entitled "History by Numbers", with the goal of introducing fourth year history students to quantitative data sources and to basic statistical concepts. This paper will discuss how students used the Nesstar WebView to access the 1871 Canadian Census data for an assignment, how they found navigating through the Census variables relatively easy and how some were easily frustrated when asked to create cross-tabulations and to interpret their findings. Despite the difficulties encountered by some, by the end of the semester there were several students who "discovered the world of data" and continue to use it to enhance their research papers and theses.
J-matrix method of scattering in one dimension: The relativistic theory

description: We make a relativistic extension of the one-dimensional J-matrix method of scattering. The relativistic potential matrix is a combination of vector, scalar, and pseudo-scalar components. These are non-singular short-range potential functions (not necessarily analytic) such that they are well represented by their matrix elements in a finite subset of a square integrable basis set that supports a tridiagonal symmetric matrix representation for the free Dirac operator. Transmission and reflection coefficients are calculated for different potential coupling modes. This is the first of a two-paper sequence where we develop the theory in this part then follow it with applications in the second.

Smart qualitative data: methods and community tools for data mark-up
Creators: name: Corti, Louise

Publisher: name: Zenodo
Year: 2005

description: This paper will describe the ESDS Qualidata demonstrator project that forms part of a wider new Uk Research Council funded initiative known as the Scheme for Qualitative Data Sharing and Research Archiving(QUADS). The Scheme's aim is to develop and promote innovative methodological approaches to the archiving, sharing, re-use and secondary analysis of qualitative research and data, and that means thinking beyond the traditional centralised data archive model (ie ESDS Qualidata). The ESDS Qualidata project is exploring methodological and technical solutions for exposing digital qualitative data to make them fully shareable and exploitable. The project deals with specifying and testing non-proprietary means of storing and marking-up data using universal (XML) standards and technologies, and proposes an XML community standard (schema) that will be applicable to most qualitative data. The second strand investigates optimal requirements for contextualising research data (e.g. interview setting or interviewer characteristics), aiming to develop standards for data documentation and ways of capturing this information. The third strand aims to use natural language processing technology to develop and implement user-friendly tools for semi-automating processes to prepare qualitative data for both traditional digital archiving and to enable more adventurous collaborative research and e-science type exploitation, like linking multiple data and information sources. The project aims to further research tools for publishing (e.g. for web interrogation) and archiving enriched marked-up data and associated research materials.
Large scale properties in turbulent spherically symmetric accretion

description: The role of turbulence in a spherically symmetric accreting system has been studied on very large spatial scales of the system. This is also a highly subsonic flow region and here the accreting fluid has been treated as nearly incompressible. It has been shown here that the coupling of the mean flow and the turbulent fluctuations, gives rise to a scaling relation for an effective "turbulent viscosity". This in turn leads to a dynamic scaling for sound propagation in the accretion process. As a consequence of this scaling, the sonic horizon of the transonic inflow solution is shifted inwards, in comparison with the inviscid flow.
