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
Hisse Senedi Fiyatları ve Türk Para Talebi Fonksiyonu İlişkili midir?
No full textUsing the Autoregressive Distributed Lag (ARDL) and Granger causality test, this study demonstrates that M1 and M2 money demand cointegrates with real income, deposit interest rate, real exchange rates, and real stock prices. Real income, deposit interest, and exchange rates are significant determinants of the Turkish economy's long-run M1 and M2 money demand. Furthermore, our findings reveal that the wealth effect of real stock prices outweighs the substitution effect within the Turkish economy. The impact of real stock prices on M1 and M2 money demand is positive and statistically significant in the long run. While M2 is more responsive to changes in real stock prices, M1 exhibits greater stability than M2. Therefore, policymakers must recognise the significant role of the stock market in the longrun money demand function within the Turkish economy and its impact on the effective implementation of monetary policy.Bu çalışma, Otoregresif Dağıtılmış Gecikme (ARDL) ve Granger nedensellik testi kullanarak hem M1 hem de M2 para talebinin reel gelir, mevduat faiz oranı, reel döviz kurları ve reel hisse senedi fiyatları ile eşbütünleşme ilişkisi sergilediğini göstermektedir. Reel gelir, mevduat faiz oranı ve reel döviz kuru, Türkiye ekonomisinde uzun dönemli M1 ve M2 para talebinin önemli belirleyicileridir. Ayrıca, bulgularımız Türkiye ekonomisinde reel hisse senedi fiyatlarının servet etkisinin ikame etkisinden daha ağır bastığını ortaya koymaktadır. Reel hisse senedi fiyatlarının M1 ve M2 para talebi üzerindeki etkisi uzun dönemde pozitif ve istatistiksel olarak anlamlıdır. M2 reel hisse senedi fiyatlarındaki değişimlere daha duyarlı iken, M1 daha istikrarlı bir görünüm sergilemektedir. Bu nedenle politika yapıcıların, hisse senedi piyasasının Türkiye ekonomisindeki uzun dönem para talebi fonksiyonundaki önemli rolünü ve para politikasının etkin bir şekilde uygulanması üzerindeki etkisini kabul etmeleri zorunludur

In-vitro application of pentoxifylline preserved ultrastructure of spermatozoa after vitrification in asthenozoospermic patients
No full textAbstract
PURPOSE:
To evaluate the effect of in vitro application of pentoxifylline (PX) on sperm parameters and ultrastructure after vitrification in asthenozoospermic patients.
MATERIALS AND METHODS:
A total of 30 asthenozoospermic semen samples (aged 25-45 years) were divided into four groups before vitrification, after vitrification, control (without PX) and experimental (with PX). In experimental group, each sample was exposed for 30 min to 3.6mmol/l PX and the control group without any treatment apposing in 370C for 30 min. After incubation, the samples were washed and analyzed again. Vitrification was done according to straw method. Eosin-nigrosin and Papanicolaou staining were applied for assessment of sperm viability and morphology, respectively. The samples without PX and post treatment with PX were assessed by transmission electron microscopy (TEM).
RESULTS:
A significant decrease in sperm motility (P ≤ .001), morphology (11.47 ± 2.9 versus 6.73 ± 2.01) and viability (73.37 ± 6.26 versus 54.67 ± 6.73) was observed post vitrification, but sperm motility (19.85 ± 4.75 versus 32.07 ± 5.58, P ≤ .001) was increased significantly following application of PX. This drug had no significant (P >.05) detrimental neither negative effect on ultrastructure acrosome, plasma membrane and coiled tail statues of spermatozoa.
CONCLUSION:
Vitrification had detrimental effects on sperm parameters, but PX reversed detrimental effects on sperm motility. However, PX had no alteration on ultrastructure morphology of human spermatozoa after vitrification
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
