No full textAbstract Purpose: The purpose of this study was to access the performance of 117 Greek National Health System (NHS) hospitals for the year 2011, to compare the findings with the results from similar studies of the previous years (2009 and 2010) and to investigate the changes during the last three years of financial crisis. Method: An input-oriented Data Envelopment Analysis was used to measure three indicators, technical, pure technical and scale efficiency indicators. Data was collected from the reports of the web-based facility (ESY.net) which was developed by the General Secretary of Ministry of Health and Social Solidarity. The input variables were the number of physicians, the number of nurses and other personnel, the number of beds and expenditures of every hospital. The output variables were the number of inpatient and outpatient visits. Hospitals were categorized into three size groups. Results: Between the years 2009-2011, all hospitals, especially middle-sized hospitals showed performance improvement on all three indicators. Specific problems were noticed mainly in large-sized hospitals. The technical efficiency of Large-sized hospitals was estimated at 80%, of Middle-sized hospitals at 82% and of Small hospitals-Health Care Centres at 89%. Pure technical and scale efficiency varied between satisfactory levels throughout the study period. Conclusion: Comparing the 2009-2011 data, an improvement of technical efficiency in NHS hospitals has been achieved up to 100%, mainly in the middle-sized hospitals. Specifically, an increase of best practice hospitals has been noted, especially in the middle and small-sized hospitals, when certain units were added the technical efficiency reached over 80%. The consequences of the spending-cuts and the constant reforms appear to have a positive effect on hospitals' efficiency. Hippokratia 2012, 16, 4: 350-35
Exploiting Satellite Broadcast Despite HTTPS
No full textHTTPS enhances end-user privacy and is often preferred or enforced by over-the-top content providers, but renders inoperable all intermediate network functions operating above the transport layer, including caching, content/protocol optimization, and security filtering tools. These functions are crucial for the optimization of integrated satellite-terrestrial networks. Additionally, due to the use of end-to-end and per- session encryption keys, the advantages of a satellite's wide- area broadcasting capabilities are limited or even negated completely. This paper investigates two solutions for authorized TLS interception that involve TLS splitting. We present how these solutions can be incorporated into integrated satellite- terrestrial networks and we discuss their trade-offs in terms of deployment, performance, and privacy. Furthermore, we design a solution that leverages satellite broadcast transmission even in the presence of TLS (i.e. with the use of HTTPS) by exploiting application layer encryption in the path between the satellite terminal and the TLS server. Our findings indicate that even if no other operation than TLS splitting is performed, TLS handshake time, which involves roundtrips through possibly a Geosynchronous satellite, can be reduced by up to 94%. Moreover, by combining an application layer encryption solution with TLS splitting, broadcast transmissions can be exploited as well as proactive caching, content pushing, request aggregation, and other optimizations

No full textA 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
