In this work we only identify the differences between Turkish

Background and aims
The ratio of the second and fourth fingers (2D:4D ratio) is a sexually dimorphic trait, with men tending to have lower values than women. This ratio has been related to prenatal testosterone concentrations and addictive behaviors including problematic video-gaming. We aimed to investigate the possible association between 2D:4D ratios and Internet addiction and whether such a relationship would be independent of impulsivity.
A total of 652 university students (369 women, 283 men), aged 17–27 years, were enrolled in the study. Problematic and pathological Internet use (PPIU) was assessed using the Internet Addiction Test (IAT). The participants also completed the Barratt Impulsiveness Scale (version 11; BIS-11) and had their 2D:4D ratios measured.
2D:4D ratios were not significantly different in women with PPIU and in those with adaptive Internet use (AIU). Men with PPIU exhibited lower 2D:4D ratios on both hands when compared with those with AIU. Correlation analysis revealed that 2D:4D ratios on both hands were negatively correlated with IAT scores among men, but not among women. The multiple linear regression analysis revealed that age, duration of weekly Internet use, impulsiveness, and 2D:4D ratios on the right hand were independently associated with IAT scores among men, and impulsivity did not mediate the relationship between 2D:4D ratios and PPIU.
For men, 2D:4D ratios on the right hand were inversely correlated with Internet addiction severity even after controlling for individual differences in impulsivity. These findings suggest that high prenatal testosterone levels may contribute to the occurrence of PPIU among men.

test were suitable for Turkishuniversity students. The study was conducted in two sequent phases. In the first phase an EFA was applied to figure out the factor structure of the Turkish version of the IAT. The EFA revealed four factors, which explained
The scientific publications of 231 chemistry professors employed at Turkish Universities are studied for a period of 10 years.
The quantitative as well as the qualitative aspects of the trends in the scientific information output of this group are analyzed
in order to evaluate the underlying facts of the recent increase in the number of publications coming from Turkey. The selected
group is a fairly good representative of the Turkish scientific community and our observations could be generalized to describe
the development of basic sciences in Turkey. We conclude that even though there exists a serious increase in the scientific
output from Turkey, a rather small portion of the studied group is responsible both for high number of publications and for
This paper tests the validity of Urquhart’s Law (“the inter-library loan demand for a periodical is as a rule a measure of
its total use”). It compares the use of print journals at the Turkish Academic Network and Information Center (ULAKBIM) with
the consortial use of the same journals in their electronic form by the individual libraries making up the Consortium of Turkish
University Libraries (ANKOS). It also compares the on-site use of electronic journals at ULAKBIM with their consortial use
at ANKOS. About 700 thousand document delivery, in-house and on-site use data and close to 28 million consortial use data
representing seven years’ worth of downloads of full-text journal articles were used. Findings validate Urquhart’s Law in
that a positive correlation was observed between the use of print journals at ULAKBIM and the consortial use of their electronic
copies at ANKOS. The on-site and consortial use of electronic journals was also highly correlated. Both print and electronic
journals that were used most often at ULAKBIM tend to get used heavily by the member libraries of ANKOS consortium, too. Findings
can be used in developing consortial collection management policies and negotiate better consortial licence agreements.
