Service-oriented models for audiovisual content storage
No full textWhat are the important topics to understand if involved with storage services to hold digital audiovisual content? This report takes a look at how content is created and moves into and out of storage; the storage service value networks and architectures found now and expected in the future; what sort of data transfer is expected to and from an audiovisual archive; what transfer protocols to use; and a summary of security and interface issues
Mining e-mail content for author identification forensics
No full textWe describe an investigation into e-mail content mining for author identification, or authorship attribution, for the purpose of forensic investigation. We focus our discussion on the ability to discriminate between authors for the case of both aggregated e-mail topics as well as across different email topics. An extended set of e-mail document features including structural characteristics and linguistic patterns were derived and, together with a Support Vector Machine learning algorithm, were used for mining the e-mail content. Experiments using a number of e-mail documents generated by different authors on a set of topics gave promising results for both aggregated and multi-topic author categorisation
Digitizing Africal local content : The way forward
No full textThis paper sought to expound on how the African local content can be preserved and
transmitted to the larger world via a successful digitization process by providing answers
to four major questions as follows: What is local content? Why do we need to digitize our
local content? How do we digitize local content? And how do the digitized local content
help in preserving and transmitting African literary and cultural heritage to the world at
large? Furthermore, recent initiatives at digitizing and transmitting local content were
highlighted while constraints to digitizing and transmitting African local content were
also identified. However, the paper concluded and made recommendations on how
Nigeria can join the rest of Africa in improving and promoting our local content in the
Global Information Infrastructure (GII), which is seen presently to be minimal
Genuine and simulated suicide notes: An analysis of content
No full textThe present study examined genuine and simulated suicide notes aiming to identify the measures of content that best differentiate between the two. Thirty-three genuine and thirty-three simulated suicide notes were content-analysed and data subjected to smallest space analysis (SSA), a Multidimensional Scaling Procedure. The core of all suicide notes was discovered to be constructed with the use of three variables: expressions of love, positive construction of partner and apologies. Furthermore, four different genuine suicide note themes (‘planned escape’, ‘negative affect and self-mitigation’, ‘positive affect and failed relationship’, ‘lack of self-acceptance’) and three simulated suicide note themes (‘escape’, ‘positive affect and self-blame’, ‘purposeless life’) were identified revealing that authentic suicide note themes were more internally consistent and clearer to interpret
Ambiguous figures and the content of experience
No full textRepresentationalism is the position that the phenomenal character of an experience is either identical with, or supervenes on, the content of that experience. Many representationalists hold that the relevant content of experience is nonconceptual. I propose a counterexample to this form of representationalism that arises from the phenomenon of Gestalt switching, which occurs when viewing ambiguous figures. First, I argue that one does not need to appeal to the conceptual content of experience or to judgements to account for Gestalt switching. I then argue that experiences of certain ambiguous figures are problematic because they have different phenomenal characters but that no difference in the nonconceptual content of these experiences can be identified. I consider three solutions to this problem that have been proposed by both philosophers and psychologists and conclude that none can account for all the ambiguous figures that pose the problem. I conclude that the onus is on representationalists to specify the relevant difference in content or to abandon their position
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

Philadelphia: John Benjamins.A main motivation for relegating Word Formation to the lexicon is the fact that its output is often non-compositional. The present article, however, presents a serious challenge to the presumed contradiction between non-compositionality and syntactic combinatorial processes. The investigation of N–N Constructs in Hebrew shows that equally syntactically complex expressions nonetheless interact differently with non-compositionality. Crucially, it is the syntactic differences between these expressions that give rise to distinct Content properties, with non-compositionality correlating not with syntactic structure as such, but with the absence of functional structure. The emerging syntactic domain of ‘word’ Content in turn allows the language learner to make informed decisions on where to look for non-compositionality and to draw the appropriate structural conclusions from its presenc
The Political J-Blogger: `Normalizing’ a New Media Form To Fit Old Norms and Practice
No full textThis study explores how the increasingly popular blog format, as adopted by journalists affiliated with mainstream media outlets, affects long-standing journalistic norms and practice. It focuses on nonpartisanship, transparency and the gatekeeping role, using a content analysis of twenty Weblogs dealing with politics or civic affairs. Although expressions of opinion are common, most journalists are seeking to remain gatekeepers even in this highly interactive and participatory format. Political j-bloggers use links extensively – but mostly to other mainstream media sites. At least in their early use, journalists are `normalizing’ the blog as a component, and in some ways an enhancement, of traditional journalistic norms and practices
Abnormal behavior of interferon-induced enzymatic activities in an interferon-resistant cell line
No full textInterferon induces two double-stranded RNA-dependent enzymatic activities: an oligoisoadenylate synthetase that converts ATP to ppp(A2'p)n5'A, and a protein phosphokinase. We have explored the level and inducibility of these two enzymes in a human cell line (HEC-1) totally insensitive to both the antiviral and the anticellular actions of interferon. The activities of both enzymes are high in untreated cells and only minor changes occur after treatment with interferon, even at high concentrations. Interferon-treated HEC-1 cells do not contain an inhibitor of the oligoisoadenylate synthetase activity. The products of this HEC-1 oligoisoadenylate synthetase consist mainly of dimers, trimers, and tetramers as found in other cell lines after interferon treatment. The synthetase level is unaffected by treating the cells with anti-interferon antiserum, indicating that the results cannot be explained by a spontaneous low production of interferon by these cells. Furthermore, virus multiplication is not inhibited, even after treatment with interferon. These observations suggest that either the two enzymatic activities do not suffice for the establishment of an antiviral state in vivo or that a regulatory control mechanism, lost in these cells and common for both enzymes, is required for the expression of the antiviral action of interferon. This might explain both the constitutivity of the two enzymes and the interferon resistance observed
Comparative Advantages, Transaction Costs and Factor Content in Agricultural Trade: Empirical Evidence from the CEE
No full textThe present study examines factor content in the CEE transition country agricultural trade. However, deviating from the traditional approach, we do not test the HOV prediction. Instead, we examine the theoretical predictions that relate the factor content of international trade to cross-country differences in technology and endowments. Our empirical findings suggest that factor content between agricultural exports and imports is rather similar in CEE. In order to explain the general lack of the CEE agricultural specialisation and the observed paradox, we attempt to identify the role of transaction costs and market imperfections in determining factor content in agricultural production and trade. We find that technological differences and factor endowment are only weak determinants of country specialisation. Transaction costs and market imperfections distort farm specialisation and organisation in CEE, and hence factor content in traded agricultural goods.Comparative Advantage, Transaction Cost, Factor Content, Trade, International Relations/Trade,
