Dimensions of civic activism and their effectiveness in exposing corruption: evidence from Italy
No full textThis article studies the influence of civic activism in exposing corruption across Italian regions.
Using different dimensions of civic activism (including local and national newspapers, the internet, blood donors, and voter turnout), we make the distinction between active (media, internet, voters) and passive (blood donors) activism. Results show interesting different impacts of civic activism on corruption. In particular, voter turnout, blood donors, and national newspaper diffusion consistently increased exposure of corruption, while the internet and local newspapers
showed opposite effects. Thus, local newspapers and the internet point to the possibility of media capture (influence) with regard to corruption exposure. The main findings hold following the substantial reforms in the nineties (called Mani Pulite)
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
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
A new India: Contestations of national identity at the crossroads of postcolonial aspirations and globalized imagination
No full textMy dissertation examines contestations of national identity and representation of individual aspirations within a globalized imagination of 21st century India. In analyzing the metaphoric construction of a New India, I look at the unrestrained urbanization that has followed economic liberalization and the political mobilization of marginalized sections of the population, also concomitantly emerging within these new urbanscapes. As they intersect with new media practices, community-building and neoliberal restructuring of the state, enterprise and the individual, the tenor of a national community, previously invested in the narrative of a glorious past emerging from classical Hindu roots seem to be merging with myriad flows of globalization, transforming the social landscape of the postcolonial nation in significant ways. In studying this, my study uses archival data and ethnographic research to adopt a critical approach to communication and cultural studies with a focus on exploring how the country’s national imagination has been formed within the coordinates of the original Nehruvian trope of the nation as “a new star… of freedom in the East” and the newest construction of “India rising,” especially as it develops with relation to conditions of globalization. It examines how globalization has reconstituted the image of the nation, the national community and national prosperity, as well as development and progress – national, regional and individual – in the minds of the ordinary citizen.Item withdrawn by Alexis Thompson ([email protected]) on 2014-04-25T13:11:04Z

Perfect Matchings in O(n log n) Time in Regular Bipartite Graphs
No full textIn this paper we consider the well-studied problem of finding a perfect matching in a d-regular bipartite graph on 2n nodes with m = nd edges. The best-known algorithm for general bipartite graphs (due to Hopcroft and Karp) takes time O(m√n). In regular bipartite graphs, however, a matching is known to be computable in O(m) time (due to Cole, Ost, and Schirra). In a recent line of work by Goel, Kapralov, and Khanna the O(m) time bound was improved first to Ō(min{m, n2.5/d}) and then to Ō(min{m, n²/d}). In this paper, we give a randomized algorithm that finds a perfect matching in a d-regular graph and runs in O(n log n) time (both in expectation and with high probability). The algorithm performs an appropriately truncated alternating random walk to successively find augmenting paths. Our algorithm may be viewed as using adaptive uniform sampling, and is thus able to bypass the limitations of (nonadaptive) uniform sampling established in earlier work. Our techniques also give an algorithm that successively finds a matching in the support of a doubly stochastic matrix in expected time O(n log² n), with O(m) pre-processing time; this gives a simple O(m+mnlog² n) time algorithm for finding the Birkhoff-von Neumann decomposition of a doubly stochastic matrix. We show that randomization is crucial for obtaining o(nd) time algorithms by establishing an Ω(nd) lower bound for deterministic algorithms. We also show that there does not exist a randomized algorithm that finds a matching in a regular bipartite multigraph and takes o(n log n) time with high probability
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)

Dissipative Range Scaling of Higher Order Structure Functions for Velocity and Passive Scalars
No full textDifferently to Kolmogorov's second similarity hypothesis, we find that the 2n-th order velocity and scalar structure functions scale with n-th order moment of the energy dissipation and the scalar dissipation, respectively. The origins of this scaling are analyzed by the transport equations of the fourth order velocity and scalar increment moments and by direct numerical simulations
