No full textA Quantile Based Test of Protection for Sale Model
No full textThis paper proposes a new test of the Protection for Sale (PFS) model by Grossman and Helpman (1994). Unlike existing methods in the literature, our approach does not require any data on political organizations. We formally show that the PFS model provides the following prediction: In the quantile regression of the protection measure on the inverse import penetration ratio divided by the import demand elasticity, its coefficient should be positive at the quantile close to one. We examine this prediction using the data from Gawande and Bandyopadhyay (2000). The results do not provide any evidence favoring the PFS model.Quantile Regression, Protection for Sale, Political Economy

On the Narumi-Katayama Index of Composite Graphs
No full textThe Narumi-Katayama index of a graph G, denoted by N K(G), is equal to the product of degrees
of vertices of G. In this paper we investigate its behavior under several binary operations on graphs. We
present explicit formulas for its values for composite graphs in terms of its values for operands and some
auxiliary invariants. We demonstrate applications of our results to several chemically relevant classes of
graphs and show how the Narumi-Katayama index can be used as a measure of graph irregularity. (doi:

Imported Katayama fever: clinical and biological features at presentation and during treatment
No full textOBJECTIVES: To investigate the characteristics of imported Katayama fever (acute schistosomiasis) as well as evolution and outcome under treatment. METHODS: Between April 2000 and September 2004, we included prospectively all patients with confirmed diagnosis of Katayama fever. Follow-up was maintained at least until 6 months after symptoms resolved. Praziquantel (PZQ) was given as soon as the diagnosis was probable, most of the time with steroids. RESULTS: Twenty-three patients were diagnosed with Katayama fever by Schistosoma egg detection and/or by seroconversion. Clinical features were non-specific, with mainly respiratory and/or gastrointestinal symptoms. Diagnosis was confirmed at presentation in 17/23 (74%) patients, of whom 15 by serology. Immediate clinical exacerbation occurred in five of nine patients not given steroids concomitantly with PZQ. After initial resolution, fever recurred in five (22%) patients. When compiling initial and recurrent episodes (n=28), respiratory symptoms tended to occur at an earlier stage after exposure, while abdominal complaints were more frequent later. All patients were completely cured, sometimes after repeated treatments. CONCLUSIONS: Clinical presentation of Katayama fever is non-specific and involves respiratory and abdominal symptoms. Recurrence of fever is not unusual despite anti-helminthic treatment. Optimal therapeutic strategy remains to be defined to prevent recurrence
Quasi-isometric embeddings from mapping class groups of nonorientable surfaces (Women in Mathematics)
No full textClassifying finitely generated groups by quasi-isometries is a key issue in geometric group theory: two groups are quasi-isometric if, roughly speaking, their word metrics are the same up to linear functions. It is known that the mapping group Mod(N) of a nonorientable surface N is a subgroup of the mapping group Mod(S) of its double covering orientable surface S. We show that the injective homomorphism is a quasi-isometric embedding. This is a joint work with Takuya Katayama
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
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)
