Bank holding companies : a better structure for conducting universal banking?
No full textBanking systems in many countries have become increasingly unstable in recent years. At the same time, market forces have pushed banks to expand into a variety of universal banking activities without impairing the stability of the banking system. The basic bank holding company proposal contains three major elements : first, any bank that wants to operate as a universal bank must first form a holding company and then conduct all riskier activities in holding company units rather than directly in the bank. The bank would continue to engage in traditional banking activities that involve the usual level of risk; second, the government would develop laws and regulations designed as safeguards to insulate the bank from any financial problems that might occur in holding company affiliates of the bank; and lastly bank regulatory authorities would impose little or no supervision on holding company units. The use of the bank holding company device to conduct universal banking activities can promise important public benefits including : 1) a sounder commercial banking system; 2) less banking regulation; and 3) greater competitive equality between banking and nonbanking units.Microfinance,Banks&Banking Reform,Financial Intermediation,Private Participation in Infrastructure,Small Scale Enterprise
Approximate Majority With Catalytic Inputs
No full textPopulation protocols are a class of algorithms for modeling distributed
computation in networks of finite-state agents communicating through pairwise
interactions. Their suitability for analyzing numerous chemical processes has
motivated the adaptation of the original population protocol framework to
better model these chemical systems. In this paper, we further the study of two
such adaptations in the context of solving approximate majority:
persistent-state agents (or catalysts) and spontaneous state changes (or
leaks).
Based on models considered in recent protocols for populations with
persistent-state agents, we assume a population with catalytic input agents
and worker agents, and the goal of the worker agents is to compute some
predicate over the states of the catalytic inputs. We call this model the
Catalytic Input (CI) model. For , we show that computing the
exact majority of the input population with high probability requires at least
total interactions, demonstrating a strong separation between the
CI model and the standard population protocol model. On the other hand, we show
that the simple third-state dynamics of Angluin et al. for approximate majority
in the standard model can be naturally adapted to the CI model: we present such
a constant-state protocol for the CI model that solves approximate majority in
total steps w.h.p. when the input margin is .
We then show the robustness of third-state dynamics protocols to the
transient leaks events introduced by Alistarh et al. In both the original and
CI models, these protocols successfully compute approximate majority with high
probability in the presence of leaks occurring at each step with probability
, exhibiting a resilience to leaks
similar to that of Byzantine agents in previous works.Comment: Updated an incorrectly-cited related wor
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
Symptom evaluation in reflux disease: workshop background, processes, terminology, recommendations, and discussion outputs
No full textThere has been no published indepth systematic evaluation of the best approaches to symptom evaluation in gastro-oesophageal reflux disease (GORD). A two day international multidisciplinary workshop was therefore held in Marrakech, Morocco, in September 2002 to address these issues. The aim of the workshop was to critically review the data regarding the reliability, processes, and priorities for symptom evaluation in GORD patients. The workshop was designed to give outputs that could be readily reported and to arrive at specific recommendations on best practice in symptom evaluation in reflux disease.J Dent, D Armstrong, B Delaney, P Moayyedi, N J Talley and N Vaki
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
