What is not available online is not worth reading?
Get PDFThis short article discusses an emerging trend in the information-seeking behaviour of scientists, i.e. mere reliance on online information. Based on a study of physicists and astronomers, this article shows that more scientists now assume that if articles are of enough quality and significance, they must be available online and vice versa. Though still in a low minority, a number of scientists believe that what is not available online is not worth the effort to obtain it
Shifts in Search Engine Development: A Review of Past, Present and Future Trends in Research on Search Engines
Get PDFThe World Wide Web has developed fast and many people use search engines to capture information from the Web. This article reviews past, present and future of search engines. Papers published in four major Web and information management conferences were surveyed to track research interests in the last five years. Web search and information retrieval topics such as ranking, filtering and query formulation are still hot topics among researchers. The most important shifts and issues of the future of search engines are mentioned too. Search engine companies are trying to capture the Deep Web and extract structured data to offer high quality results. Using Web page structure, shared search engines, expert recommendations and different mobile search facilities seem to be features of the next generation of search engines
E-print depositing behavior of physicists and astronomers: an intradisciplinary study
Get PDFThis article investigates the e-print depositing behavior of physicists and astronomers. Fifty-six PhD students and staff at the Department of Physics and Astronomy at the University College London were interviewed. A survey was also carried out (47.1% response rate). The study investigates the relation between variables such as research area, type of research (theoretical, experimental and so on), and the amount of reading on the patterns of e-print depositing. The findings showed that clear intradisciplinary differences exist among different subfields of physics and astronomy
Communication and information-seeking behavior of PhD students in physicists and astronomy
Get PDFAs a part of a wider doctoral research, this paper deals with the communication and information-seeking behavior of research (PhD) students in physics and astronomy. Based on a qualitative case study of PhD students in the Department of Physics and Astronomy at University College London, this study seeks to derive behavioral patterns in information-seeking activities of PhD students. The study aims to investigate the intradisciplinary differences in information-seeking activities of physicists and astronomers. The findings show the high reliance of PhD students in physics and astronomy on electronic journals and their low use of libraries. The findings reveal differences in the information-seeking patterns of students who conduct theoretical research and those of whom are involved in experimental research. The research highlights the need for the study of small subject communities within academic disciplines instead of studying users in a broad subject area such as physics as one single domain
Information-seeking behaviour of physicists and astronomers
Get PDFPurpose – The study examines two aspects of information seeking behaviour of physicists and astronomers including methods applied for keeping up-to-date and methods used for finding articles. The relationship between academic status and research field of users with their information seeking behaviour was investigated.
Methodology/approach – Data were gathered using a questionnaire survey of PhD students and staff of the Department of Physics and Astronomy at University College London; 114 people (47.1 per cent response rate) participated in the survey.
Findings – The study reveals differences among subfields of physics and astronomy in terms of information-seeking behaviour, highlights the need for and the value of looking at narrower subject communities within disciplines for a deeper understanding of the information behaviour of scientists.
Originality/value – The study is the first study to deeply investigate intradisciplinary dissimilarities of information-seeking behaviour of scientists in a discipline. It is also an up-to-date account of information seeking behaviour of physicists and astronomers
Pt–M (M = Au and Tl) Dative Bonds Using Bis(cyclometalated)platinum(II) Complexes
Get PDFSymmetrical and unsymmetrical
biscyclometalated platinum(II) complexes
[Pt(ptpy)2], 1, and [Pt(ptpy)(bppy)], 2, in which ptpy = deprotonated 2-(p-tolyl)pyridine
and bppy = deprotonated 2-(3-bromophenyl)pyridine, have been prepared
from the reaction between tris(pentafluorophenyl)borane, B(C6F5)3 and 1 equiv of monocyclometalated complexes
[PtMe(ptpy)(ptpyH)], B, and [PtMe(ptpy)(bppyH)], C, respectively. The solid-state structures of 1 and 2 have been determined by X-ray crystallography.
The reaction of 1 with 1 equiv of TlPF6 or
[Au(PPh3)]OTF resulted in the production of heteronuclear
complexes [Pt(ptpy)2Tl]PF6, 3 and
{Pt(ptpy)2[Au(PPh3)]}OTF, 4, respectively.
X-ray diffraction data showed that in solid state, complex 4 exists as a mixture of supported and unsupported PtII–AuI-bonded structures, whereas complex 3 consists of an infinite helical chain structure built up by unsupported
Pt–Tl dative bonds. Absorption, emission, and NMR spectroscopy
data showed that both Pt–Tl and Pt–Au bonds in 3 and 4 have dynamic behavior. The low-temperature 1H, 31P{1H}, and exchange spectroscopy
NMR of 4 revealed two dynamic behaviors involving the
rupture of the Au–Cipso bond as
well as the dissociation–association of the [Au(PPh3)]+ and Pt(ptpy)2 fragments. All complexes
displayed bright emission in the solid state, and their absorption
and emission properties have been investigated both experimentally
and by time-dependent density functional theory calculations

Peranan Letnan Jenderal TNI Purn Syarwan Hamid Dalam Reformasi 1998 – 1999
Get PDFThe background of this thesis is to know the role of Lieutenant General TNI Purn Syarwan Hamid in supporting the demands of the students behind the shift of the New Order to the Reform, whereby he served as Vice Chairman of the House of Representatives / Representative representatives of the Armed Forces (FABRI). The aims of this research are: (1) Knowing the life history of Lieutenant General TNI Purn Syarwan Hamid (2) Knowing the role of Lieutenant General TNI Purn Syarwan Hamid in the reform of 1998 - 1999 (3) To find out what ever in the struggle of Lieutenant General TNI Purn Syarwan Hamid for Riau Province when he served as Minister of Home Affairs RI 1998 - 1999 Development Reform Cabinet. The method used in this research is the method of historical research, because this research takes the object of events that occurred in the past. In addition to historical research methods (history), the author also uses biographical analysis techniques, this technique is a method of analyzing one's life history. The results obtained that the role of Syarwan Hamid in reform can be seen in two dimensions. The first dimension concerns Syarwan's political role and choice as the reform movement begins to roll. Second, the role of Syarwan in the position of Minister of Home Affairs Mr. Syarwan Hamid who is the Vice Chairman of the House of Representatives Faction as a person who finalizes the reform movement to achieve political success. Mr. Syarwan also gave the students the opportunity to keep occupying the DPR / MPR building while taking action to discuss accepting student demands In the lead up to the reformation, Pak Syarwan also received the nods of action from various universities in Jakarta to agree on the strategy of occupying the parliament building safely and effectivel
Blended Library and Multimedia Model in Geography Teaching
Get PDFLibraries have been established and always utilized in old fashion and modern school and academic environments in order to support educational programs. However, new instructional technologies have changed traditional library-based teaching models. Multimedia approach has shown successful in teaching different courses to different learners. However, there is little known how a combination of library and multimedia approach can be implemented and measured in teaching. This paper focuses on an innovative approach in which a blended library and multimedia model has been developed to teach geography concepts. It was implemented in teaching geography in a first grade class in an Iranian secondary school. The empirical results revealed the effectiveness of the blended model in learning and retention of geography
Article title type and its relation with the number of downloads and citations
Get PDFTitle of an article can be descriptive, declarative or a question. It plays important role in both marketing and findability of article. We investigate the impact of the type of article titles on the number of citations and downloads articles receive. Number of downloads and citations for all articles published in six of PLoS (Public Library of Science) journals (2172 articles) were obtained from PLoS and type of each article's title (including descriptive, indicative and question) was determined as well as the number of substantive words in title (title length). Statistical difference and correlation tests were carried out. The findings showed that differences exist between articles with different types of titles in terms of downloads and citations, especially articles with question titles tended to be downloaded more but cited less than the others. Articles with longer titles were downloaded slightly less than the articles with shorter titles. Titles with colon tended to be longer and receive fewer downloads and citations. As expected, number of downloads and citations were positively correlated
