Inscriptions du Musee de Ioannina (Τίτλος περίληψης)
No full textσ. [611-643Κείμενο στα ελληνικά με περίληψη στα γαλλικά με τον τίτλο: Inscriptions du Musee de Ioannina"Η μελέτη αυτή αποτελεί κριτική επανέκδοση των ελληνικών επιγραφών της μεγάλης αίθουσας του μουσείου Ιωαννίνων από φοιτητές που παρακολούθησαν το μάθημα της Επιγραφικής το χειμερινό εξάμηνο 1986-1987..."--παρέχεται από τη συγγραφέαLe present travail est une reedition des inscriptions grecques de la grande salle du musee de Ioannina par les etudiants qui ont suivi les cours d* fipigraphie grecque pendant le premier semestre de Γ annee 1986-87. Sa realisation a ete rendue possible grace a la collaboration de Γ fiphorie qui a facilite les travaux pratiques dans le musee.
Le lemme epigraphique est du aux etudiants qui sont aussi responsables de P etablissement des textes: lectures nouvelles, obvservations permettant de rejetter des restitutions deja proposees ou confirmant des restitutions jusqu’alors incertaines. Tout cela a regu mon aval. Certai- nes lectures ou remarques plus complexes sont le resultat de ma collaboration avec les etudiants lorsque nous avons revu les pierres. Je suis, quant a moi, responsable de la description des pierres et, pour de raisons d* homogeneity, de la redaction du recueil. L΄ etablissement du lemme epigraphique s* est particuli£rement heurte au probleme du retard de la parution de certaines revues grecques comme Γ Arch. Delt., Chron., retard qui fait qu’une inscription apparait souvent plus tot dans les Chroniques de revues comme le BCH ou le JHS que dans son editio princeps. Pour des raisons analogues, il n* a pas ete toujours possible d' indiquer, entre parentheses, a la suite d* une inscription le lemme du Bull. ep. ou du SEG qui s’y rapporte.

A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc

PGHSs catalyze the oxygenation of fatty acyl substrates (FAH) such as arachidonic acid (AA). This is the committed step in the generation of prostaglandin H2 (PGH2). PGH2 is the substrate for five downstream isomerases that lead to the generation of prostaglandins. Prostaglandins mediate a variety of physiological effects, such as pain, inflammation, fever, vascular homeostasis, and parturition, by their actions at several prostaglandin-specific G-protein coupled receptors (GPCRs). The endogenous ligands for the cannabinoid receptors, arachidonoyl ethanolamine (AEA) and 2-arachidonoyl glycerol (2-AG) are substrates for the second isoform of PGHS, PGHS-2. Their oxygenation leads to the generation of AEA and 2-AG derived prostaglandins (PG-EAs and PG-Gs). PG-Gs have been shown to have unique actions at yet to be identified GPCRs including, mobilizing Ca2+ at the picomolar level in cell culture, and causing a concentration dependent hyperalgesia (exaggerated pain) and allodynia (pain in response to non-pain evoking stimuli). To determine the biochemical determinants of the oxygenation of 2-AG by PGHS-2, I compared the abilities of AA derived hydroperoxides to 2-AG derived peroxides as substrates and activators of the oxygenase function of PGHS. I demonstrated that PGG2 and PGG2-G were both equivalent substrates for PGHS-2. Interestingly, the oxygenation of 2-AG demonstrated and increased need for the concentrations of peroxide required to activate its oxygenation. In the presence of increased peroxide scavenging by glutathione peroxide (GPx), the oxygenation of 2-AG was almost abrogated compared to relatively unaffected AA oxygenation. Specifically, I demonstrated that the depletion of the membrane associated GPx (GPx4), leads to increased oxidant stress and peroxide tone, and significantly increased oxygenation of 2-AG in murine derived cells.
These results led us to conclude that the oxygenation of 2-AG is exquisitely sensitive to the concentration of oxygenase activating peroxide. Chemical ligands specifically designed to target the peroxidase active site of PGHS have to date not been reported. I designed a chemical mimic of PGHS-2 substrate PGG2 and developed a chemical ligand that inhibited the turnover of peroxide at the peroxidase active site of PGHS. This lead compound forms a new class of molecule that can specifically and potently inhibit the oxygenation of 2-AG by PGHS-2, while having no impact on AA oxygenation. It could form a useful tool for the dissection of the physiological role of PGHS-2 mediated 2-AG oxygenation
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Market dynamics as a driver towards the evolution of research needs : the case of up-flow anaerobic sludge blanket seeding granules

research needs : the case of up-flow anaerobic sludge
blanket seeding granules, Water SA, 39(1):131-142, doi:http://dx.doi.org/10.4314/wsa.v39i1.13.The original publication is available at http://www.wrc.org.zaMarket dynamics offer positive (incentive) or negative (disincentive) feedback loops that shape the research needs for, or
certain aspects of, a particular technology. Our case study results illustrate how market dynamics have influenced the evolution of research needs in the wastewater treatment sector, with specific emphasis on research on the seeding granules used to
start up-flow anaerobic sludge blanket (UASB) reactors. Because of insufficient data on the actual market demand for seeding
granules for UASB plants, surrogate data, on the number of UASB plants installed internationally from 1970 to 2007, were
used to predict the potential future demand for seeding granules. Secondly, we also determined whether or not such a demand
would provide sufficient economic justification for the installation of one or more plants for manufacturing seeding granules
in South Africa. The direct relationship between the demand for seeding granules and increased numbers of UASB plants
was based on the premise that the start-up of each plant required a seeding inoculum before effluent could be treated. Three
methods were used to obtain the data used in this study, namely: a literature survey, a questionnaire survey, and interviews
with people having expert knowledge of wastewater treatment technologies. Our findings suggest that the UASB technology
has largely been marginalised in the wastewater treatment market because of the introduction of competing technologies,
and due to high initial capital costs. As a result, South African market demand for the seeding granules is likely to be very
small or non-existent, because the number of new UASB plants installed per year is likely to decrease in future. Secondly, our
research suggests that market dynamics, political contexts and technologies will continue to change, exerting an increasing
downward influence on the UASB technology over time.Publisher's versio
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
