Future of Cultural Heritage

ABSTRACT

Everything we do, create, and produce, such as intellectual and artistic works, performances, and so forth, can be defined as culture. We own a very rich cultural heritage of the past. Yet, the common cultural heritage that belongs to the humanity continues to be looted and destroyed due to negligence, armed conflicts, and wars. In this article, the causes of the destruction of cultural heritage and the question of to whom the neglected cultural heritage belongs are discussed and the economic and social values of cultural heritage are examined by means of the game theory.     

Does Urquhart’s Law hold for consortial use of electronic journals?

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.

Cost-effective synthesis of polyricinoleate: Investigation of coating characteristics,in vitro degradation,and antibacterial activity

Ricinoleic acid (RA) is a component of various bio-based copolymers. However, high-molecular weight polyricinoleate homopolymers are not widely investigated due to high cost of commercial monomer and catalysts. In this work, we present low-cost approach for the synthesis of high-molecular-weight polyricinoleate by preparing large amount of pure monomer and use of lipozyme TL IM as catalyst. First, polymerization conditions were optimized and comparative studies of medium-molecular-weight polyricinoleate (PRA-M) of M_w = 30 000 gmol⁻¹ and high-molecular-weight polyricinoleate (PRA-H) of M_w = 72 000 gmol⁻¹ were conducted. Polyricinoleates were characterized by common spectroscopic, chromatographic, and thermal methods. Solvent casting of polyricinoleates resulted in thin and continuous coating with perfectly smooth surface under SEM observation. AFM analysis of PRA films showed that surface roughness decreased with increasing molecular weight of polyricinoleate (roughness PRA-M = 68.39 nm and PRA-H = 57.36 nm). Degradation studies under in vitro conditions showed that both PRA-M and PRA-H showed good stability with only ~2% of mass loss after 6 months, possibly due to its hydrophobic nature and relatively high-molecular weight. In contrast to RA, PRA-M and PRA-H do not have significant antibacterial effect on Staphylococcus aureus and Escherichia coli. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

Related records retrieval and pennant retrieval: an exploratory case study

The Related Records feature in the Web of Science retrieves records that share at least one item in their reference lists with the references of a seed record. This search method, known as bibliographic coupling, does not always yield topically relevant results. Our exploratory case study asks: How do retrievals of the type used in pennant diagrams compare with retrievals through Related Records? Pennants are two-dimensional visualizations of documents co-cited with a seed paper. In them, the well-known tf*idf (term frequency*inverse document frequency) formula is used to weight the co-citation counts. The weights have psychological interpretations from relevance theory; given the seed, tf predicts a co-cited document’s cognitive effects on the user, and idf predicts the user’s relative ease in relating its title to the seed’s title. We chose two seed papers from information science, one with only two references and the other with 20, and used them to retrieve 50 documents per method in WoS for each of our two seeds. We illustrate with pennant diagrams. Pennant retrieval indeed produced more relevant documents, especially for the paper with only two references, and it produced mostly different ones. Related Records performed almost as well on the paper with the longer reference list, improving remarkably as the coupling units between the seed and other papers increased. We argue that relevance rankings based on co-citation, with pennant-style weighting as an option, would be a desirable addition to WoS and similar databases.

     

Contribution of Turkish Researchers to the World's Biomedical Literature (1988–1997)

The contribution of Turkish researchers to positive sciences is increasing. Turkish scientists published more than 5100 articles in 1998 in scientific journals indexed by the Institute for Scientific Information's Science Citation Index, which elevated Turkey to the 25^th place in the world rankings in terms of total contribution to science. In this paper, we report the preliminary findings of the bibliometric characteristics (authors and affiliations, medical journals and their impact factors, among others) of a total of 8442 articles published between 1988 and 1997 by scientists affiliated with Turkish institutions and indexed in the MEDLINE database.     

Contribution of Hacettepe University Faculty of Medicine to the world's biomedical literature (1988-1997)

The contribution of Turkish researchers to sciences is increasing. Turkish scientists published more than 6.000 articles in 1999 in scientific journals indexed by the Institute for Scientific Information"s Science Citation Index, which puts Turkey to the 25^th place in the world rankings in terms of total contribution to science. The number of biomedical publications authored by Turkish scientists is increasing faster than that of engineering and other non-medical sciences, which might be one of the main causes of the steep rise in Turkey"s rankings that we have been witnessing in recent years. More specifically, researchers affiliated with Hacettepe University produce almost a quarter of all the biomedical publications of Turkey that appear in international biomedical literature. In this paper, we report the findings of the bibliometric characteristics (authors and affiliations, medical journals and their impact factors, among others) of a total of 1.434 articles published between 1988 and 1997 by scientists affiliated with Hacettepe University Faculty of Medicine and indexed in MEDLINE, a well-known biomedical bibliographic database. This revised version was published online in June 2006 with corrections to the Cover Date.     

Tetrodotoxin-sensitive action potentials in smooth muscle of mouse vas deferens

Action potentials were recorded during impalements of some but not all smooth muscle cells of mouse vas deferens in response to both nerve stimulation and intracellular current injection. They were resistant to blockade by nifedipine (0.1-1.0 microM) but were blocked by tetrodotoxin (TTX, 0.2-1.0 microM) when this was added in the presence of nifedipine. It is suggested that voltage-dependent sodium (Na+) channels are present in mouse vas deferens that function to amplify calcium (Ca2+) influx through voltage-dependent Ca2+ channels.
