An analysis of the output of the literature scanned in Engineering Index during 1970–84 on solar power research indicates that the growth of the literature had been vigorous after the energy crisis in 1973 till 1982. The number of papers at conferences are quite close to the number of references in journals. The area of solar collectors and solar cells has received maximum attention. Publication output of literature by different countries follows the trend in basic sciences with USA being the major producer. The research activity became global after the energy crisis. Performance of the developed countries is low in some fields of solar power.
Summary This study examines the bibliometrics of the controversial scientific literature of Polywater research, focusing on publication types (books, journal publications, conference proceedings, and technical reports). Publication (P) frequency is used to measure publication “shape' or pattern and output, citations per publication (CPP) for impact, author self-citations (SC) and uncited publications (UP) for their effect on P and CPP. Findings show an epidemic publication pattern, journal publications with the highest P, books with the highest CPP, and insignificant SC and UP. Comparisons to several non-controversial scientific literatures suggest that these findings may be common to other controversial scientific literatures.
The Author is sceptical about the feasibility of region's comparative literature for three reasons: 1. The impossibility of
defining the region (Central or Eastern Europe); 2. The lack of literary community of (any) region; 3. The lack of experts.
Studies the relation between growth rates and obsolescence rates and half-life of theoretical population genetics literature.
Explores the application of lognormal distribution in age distribution of citations over a period of time.
Compulsive sexual behavior (CSB) is a common disorder featuring repetitive, intrusive and distressing sexual thoughts, urges and behaviors that negatively affect many aspects of an individual’s life. This article reviews the clinical characteristics of CSB, cognitive aspects of the behaviors, and treatment options.
We reviewed the literature regarding the clinical aspects of CSB and treatment approaches.
The literature review of the clinical aspects of CSB demonstrates that there is likely a substantial heterogeneity within the disorder. In addition, the treatment literature lacks sufficient evidence-based approaches to develop a clear treatment algorithm.
Although discussed in the psychological literature for years, CSB continues to defy easy categorization within mental health. Further research needs to be completed to understand where CSB falls within the psychiatric nosology.

A bibliometric analysis of agricultural literature published in Malaysia between 1981–1990 was undertaken. The analysis shed light on the key journals that published agricultural literature; on the forms of publications which are resorted to in the communication of research results; on the subject areas which are well written on and those that have been neglected; on the nature of contributions made by Malaysian authors; on the publishing practice of corporate bodies and on the number of publications produced each year.
“Eastern Europe,” as a geopolitical term coined in the Cold War, not only refers to a regional demarcation, but also carries
specific political, historical and cultural connotations, especially in a Chinese context. The political situation, historical
experience and cultural character of East-European countries were shared and could easily be understood by the Chinese, who
have gained their national consciousness and independence as well as aspired for modernity by fighting the oppression and
invasion of the foreign powers, and through learning from and resisting the Western empires at the same time. East-European
literature has, therefore, exerted particular influence on modern Chinese literature at the time of its transition from the
traditional. This article attempts to reveal the political, geographical, historical and cultural similarities shared by East-European
countries and their significance to modern China. Then it makes a survey of the introduction, reception and influence of East-European
literature in China, taking Petőfi Sándor, Bertolt Brecht and Milan Kundera as examples to show the significance of East-European
literature to modern Chinese literature.
Using the subjects desalination and educational psychology, the scatter of periodical articles over periodical titles was compared at two levels, the second level being a random sample of periodical articles cited by the first level. Several measures were used to compare the extent of scatter at the two levels. Some methods commonly used in bibliometrics produced conflicting evidence on whether the citing literature (first-level) or the cited (second-level) was more scattered. A computer-intensive sampling procedure, known as the Bootstrap method, was then used to estimate the scatter of the total cited population from the scatter of the empirical sample. Cumulative distributions were prepared to show what percentage of periodicals accounted for various percentages of articles at each level of scatter. Only at the 90th percentile of articles did the percentage of periodical titles in the cited literature significantly exceed that of the citing literature. At the tail-end of the Bradford-type distribution, the cited literature appears to be more scattered than the literature citing it.
The present study explores the characteristics of hydrogen energy literature from 1965 to 2005 based on the database of Science
Citation Index Expanded (SCIE) and its implication using the bibliometric techniques. The results of this work reveal that
the literature on hydrogen energy grows exponentially with an annual growth rate of about 18% for the last decade. Most of
document type is in the form of journal articles or meeting abstracts, constituting 90.17% of the total literature and English
is the predominant language (94.66%). USA, Japan and China are the three biggest contributing countries on hydrogen energy
literature publishing, 25.8%, 14.9%, 7.7%, respectively. The Chinese Academy of Sciences in China is the largest contributor
publishing 308 papers. The journal literature on hydrogen energy does not confirm the typical S-shape for the Bradford-Zipf
plot, but five core journals, i.e. International Journal of Hydrogen Energy, Journal of Power Source, Journal of the Electrochemical Society, Solid State Ionics,
and Electrochimica Act, contributing about 41% can be identified. Journals with highly cited articles and most highly cited articles are also identified,
in which the most highly cited article receives more than 1,000 citations.
