The great importance of titles being highly informative is almost unanimously accepted in literature, assuming that the more
informative titles are, the more effectively they serve their functions. The most common measure of title “informativeness”
has been the number of “significant” (i.e., non-trivial) words included in it, and one of the factors which might be associated
with it is the length of the paper, measured by its number of pages. The present study attempted to test, in a large group
of journals from different areas and over six decades, the hypothesis that a paper with more pages will have more “significant”
words in its title. Large samples of original research papers were drawn from each decade year of twenty-four leading journals
selected from the sciences, the social sciences and the humanities. For each paper, the number of “significant” words in the
title was correlated with the number of pages. Findings indicate a difference between the scientific journals on the one hand,
and the social sciences and humanities journals on the other. A moderate positive correlation was found in most scientific
journals for many periods. In the social sciences journals, and to a greater extent, in the humanities journals, a significant
positive correlation was limited to only a few periods, while the rest showed a very low correlation, or even a negative one.
The different findings for the sciences are perhaps attributable to their unique inherent features.

The main purpose of this study was to evaluate the global progress and quantitative assessment of current research trends
on family therapy, using a bibliometric approach and exploring related literature in the Social Science Citation Index (SSCI)
database from 1992 to 2009. This study used the bibliometric arrropach to learn about the subject categories, core journals,
top countries and leading research institutes in publication, most frequently used author keywords, and most frequently used
KeyWords Plus. Also, this study used a “word cluster analysis” method to locate research hot topics. A majority of the subject
categories were located in clinical psychology and family studies. The core journals for family therapy located in Journal of Marital and Family Therapy, Contemporary Family Therapy, and Journal of Family Therapy. The US ranked as the top country of world articles with the highest h-index, followed distantly by the UK and Germany. The
leading research institutes were Purdue University, University of Miami, and Brigham Young University. “Adolescents” and “adolescent”
were highly used words in article titles. Next, the top three most frequently used author keywords were “anorexia nervosa”,
“adolescents”, and “psychotherapy”. Finally, the top three most frequently used KeyWords Plus were “psychotherapy”, “children”,
and “intervention”. Based on “word cluster analysis” to determine the research hotspots, the research hot topics of family
therapy fall into three categories: treated subjects, treated matters, and treatment issues. The research trend in family
therapy seems to involve the therapist often treating adolescents or children for eating disorders, substance abuse, depression,
or schizophrenia. During treatment or therapy, therapists and researchers must pay attention to the issues of gender, training,
and therapeutic alliance. 相似文献

The relative occurrence of the words “surprising” and “unexpected” in the titles of scientific papers was 11 times more common
in 2001–2005 than in 1900–1955. However, papers which had titles containing one of these words did not receive enhanced numbers
of citations. Both words (and also adjectives “unusual” and “unfortunately”) are used significantly more frequently in science
than in social sciences and humanities. The distribution of the statements of surprise is not random in scientific literature
(chemistry journals ranked highest in the number of papers claiming “surprising” or “unexpected” results) and may reflect
the level of maturity of a discipline. 相似文献

The great importance of titles being highly informative is almost unanimously accepted in literature, assuming that the more informative titles are, the more effectively they serve their functions. The most common measure of title informativeness has been the number of substantive words included in it, and one of the factors which might be associated with it is the number of authors. The present study attempted to test, in a large group of journals fromdifferent areas, and over six decades, the hypothesis that a paper signed by a larger number of authors will have more substantive words in its title. Large samples of original research papers were drawn from each decade year of fourteen leading journals. For each paper, the number of substantive words in the title was correlated with the number of authors. Findings indicate a difference between the scientific journals on the one hand, and the social sciences and humanities journals on the other. A moderate positive correlation was found in most scientific journals (excluding mathematics) for many periods. In the social sciences journals, and to a greater extent, in the humanities journals, a significant positive correlation was limited to only a few periods, while the rest showed a very low correlation, or even a negative correlation. The different findings for the sciences may be somehow associated with their higher rate of multiple authorship.Paper presented at the Fourth International Conference on Bibliometrics, Informetrics and Scientometrics in Berlin (Germany), September 11–15, 1993. 相似文献

This paper presents a detailed chronological survey of papers published in the journal titled Water Research which started publication since 1967. This current investigation reviews publication patterns between 1967 and 2008. An analysis
of the research performance according to publication output, distribution of words in article title, author keywords, and
keywords plus. Performances of countries, institutes, and authors, including total, single, collaborative, first author, and
corresponding author publications were analyzed. The most-frequently cited articles each year and the articles of the highest
impact in 2008 were also reported. Results showed that “activated sludge” was the most frequently used author keyword, followed
by “adsorption,” and “drinking water.” Authors from 114 different countries/territories published in the journal, with the
most articles submitted by authors from the USA. 相似文献

The modern scientific and ordinary language contains several specific terms which refer to the words “vegetative”or “vegetate”
as in “persistent vegetative state” or “human vegetable”.There is a long tradition from ancient times until today to compare specific functions and situations concerning human beings
with the state of plants, e.g. in natural philosophy, medicine or ethics. A specific “vegetative terminology” has been established
in medicine around 1800 in anatomical, physiological and clinical considerations (e.g. on the autonomous nervous system since
Reil).The following paper presents firstly the historical background and some stations in the use of this vegetative terminology
within the history of ideas and medicine especially around 1800. The second part presents a bioethical approach to problems
of a human vegetative state or “human vegetable” by Hans Jonas.

Based on the citation data of journals covered by the China Scientific and Technical Papers and Citations Database (CSTPCD), we obtained aggregated journal-journal citation environments by applying routines developed specifically for this
purpose. Local citation impact of journals is defined as the share of the total citations in a local citation environment,
which is expressed as a ratio and can be visualized by the size of the nodes. The vertical size of the nodes varies proportionally
to a journal’s total citation share, while the horizontal size of the nodes is used to provide citation information after
correction for the within-journal (self-) citations. In the “citing” environment, the equivalent of the local citation performance
can also be considered as a citation activity index. Using the “citing” patterns as variables one is able to map how the relevant
journal environments are perceived by the collective of authors of a journal, while the “cited” environment reflects the impact
of journals in a local environment. In this study, we analyze citation impacts of three Chinese journals in mathematics and
compare local citation impacts with impact factors. Local citation impacts reflect a journal’s status and function better
than (global) impact factors. We also found that authors in Chinese journals prefer international instead of domestic ones
as sources for their citations. 相似文献

We consider the “Matthew effect” in the citation process which leads to reallocation (or misallocation) of the citations received
by scientific papers within the same journals. The case when such reallocation correlates with a country where an author works
is investigated. Russian papers in chemistry and physics published abroad were examined. We found that in both disciplines
in about 60% of journals Russian papers are cited less than average ones. However, if we consider each discipline as a whole,
citedness of a Russian paper in physics will be on the average level, while chemistry publications receive about 16% citations
less than one may expect from the citedness of the journals where they appear. Moreover, Russian chemistry papers mostly become
undercited in the leading journals of the field. Characteristics of a “Matthew index” indicator and its significance for scientometric
studies are also discussed. 相似文献

It has already been pointed out that the foreign language barrier is probably the greatest impediment to the free flow and
transfer of information. This barrier is even growing as scientists of more and more countries publish in their own languages.
Almost all studies addressing the language barrier problem were conducted from an Anglo-Saxon perspective, limiting their
scope to English-language sources or English speakers. Little research has been devoted to studying and measuring language
preference among non-English-speaking scholars.
This article reviews measures proposed in former studies such as the “relative own-language preference” indicator, and the
“straight odds ratio”, pointing out their advantages and drawbacks. Two new refined measures (in both “raw” and normalised
versions) are offered, claiming to be free of these drawbacks, and thus enabling a better and more reliable comparison between
journals of different languages. Practical use of the proposed measures is illustrated by applying them to findings of a former
language-citation study done on nine sociology journals. 相似文献

Titles constitute the most concise statement of a document's content, and are heavily used by information retrieval systems.
Consequently, the great importance of titles being highly informative is indisputable. The most common measure of title ‘informativity’
has been the number of ‘substantive’ words it includes. Previous studies found significant differences between journals of
different subject fields, in the sciences and the social sciences, regarding the number of substantive words in article titles.
However, unlike the sciences and the social sciences, very little research has been done onhumanities journals. Examining title informativity in a group of eighteen leading English-language journals, covering various humanities
disciplines, from 1940 to 1990, the present study searched for possible differences between the humanities journal and the
scientific and social sciences ones, concerning patterns of title informativity. Generally, considerable differences were
found in the number of substantive words in article titles between the various humanities journals checked. On the other hand,
a comparison of thegroup-average means and medians of the humanities journals to group figures of journals from the sciences and the social sciences indicates
significant differences for almost all decade years studied. However, titles of papers in humanities journals did follow the
general trend of increase in informativity, although in a slower pace. Possible explanations of these differences are discussed
and areas for further study are suggested.

To assess the probability of success of an analgesic drug we have proposed a bibliometric indicator, the Top Journals Selectivity
Index (TJSI) (Kissin 2011). It represents the ratio (as %) between the number of all types of articles on a particular drug in the top 20 biomedical
journals and the number of articles on that drug in all (>5,000) journals covered by Medline over the first 5 years after
that drug’s introduction. The aim of this study was to demonstrate that TJSI may be used for the assessment of follow-on drugs
(those that follow a first-in-class drug). The study tested two hypotheses. First, TJSI can detect the difference (in the
same class) between drugs with distinguishing features and drugs without them (“me-too” drugs) better than other publication
indices, i.e., the number of all types of articles on a drug in journals presented by Medline (AJI), and the number of articles
covering only randomized controlled trials (RCT). Second, there is a relationship between the TJSI of “me-too” drugs and the
order (sequential number) in which those drugs reached the market. The study was based on drug classes approved for marketing
between the 1960’s and the early 2000’s. The eight classes that had 4 or more drugs were included for analysis. Five specific
indicators were used to determine drug’s distinguishing pharmacological properties. It was found that TJSI can detect the
difference between follow-on drugs with distinguishing features and those without them better than the other publication indices
(AJI or RCT). Our analysis also demonstrated a negative correlation (r = −0.372, p = 0.014) between the TJSI of drugs without distinguishing features (“me-too” drugs) and the order of the drug’s market entry.
This implies that TJSI could be useful for the assessment of situations with multiple market entrants in the same class when
a new addition has a questionable value. 相似文献

The output of female researchers in Iceland, relative to that of males, can be investigated because typically their “surnames”
end in“dottir” whereas the names of males end in “son”. Over the 21 years from 1980 to 2000, there has been a rise in female:
male output from 8% to about 30%. It is higher in the life sciences (biomedical research, biology and clinical medicine) but
lower where there is also foreign co-authorship, suggesting that females are less able to make overseas contacts through travel.
There appears to be no difference in the quality of female and male research output, as measured either by journal impact
categories or by citations.

Summary We present a new approach to study the structure of the impact factor of academic journals. This new method is based on calculation
of the fraction of citations that contribute to the impact factor of a given journal that come from citing documents in which
at least one of the authors is a member of the cited journal's editorial board. We studied the structure of three annual impact
factors of 54 journals included in the groups “Education and Educational Research” and “Psychology, Educational” of the Social
Sciences Citation Index. The percentage of citations from papers authored by editorial board members ranged from 0% to 61%.
In 12 journals, for at least one of the years analysed, 50% or more of the citations that contributed to the impact factor
were from documents published in the journal itself. Given that editorial board members are considered to be among the most
prestigious scientists, we suggest that citations from papers authored by editorial board members should be given particular
consideration. 相似文献

There are few comprehensive studies and categorization schemes to discuss the characteristics for both data mining and customer
relationship management (CRM) although they have already become more important recently. Using a bibliometric approach, this
paper analyzes data mining and CRM research trends from 1989 to 2009 by locating headings “data mining” and “customer relationship
management” or “CRM” in topics in the SSCI database. The bibliometric analytical technique was used to examine these two topics
in SSCI journals from 1989 to 2009, we found 1181 articles with data mining and 1145 articles with CRM. This paper implemented
and classified data mining and CRM articles using the following eight categories—publication year, citation, country/territory,
document type, institute name, language, source title and subject area—for different distribution status in order to explore
the differences and how data mining and CRM technologies have developed in this period and to analyze data mining and CRM
technology tendencies under the above result. Also, the paper performs the K–S test to check whether the analysis follows
Lotka’s law. The research findings can be extended to investigate author productivity by analyzing variables such as chronological
and academic age, number and frequency of previous publications, access to research grants, job status, etc. In such a way
characteristics of high, medium and low publishing activity of authors can be identified. Besides, these findings will also
help to judge scientific research trends and understand the scale of development of research in data mining and CRM through
comparing the increases of the article author. Based on the above information, governments and enterprises may infer collective
tendencies and demands for scientific researcher in data mining and CRM to formulate appropriate training strategies and policies
in the future. This analysis provides a roadmap for future research, abstracts technology trends and facilitates knowledge
accumulations so that data mining and CRM researchers can save some time since core knowledge will be concentrated in core
categories. This implies that the phenomenon “success breeds success” is more common in higher quality publications. 相似文献

A bibliometric analysis was performed in this work to determine research trends of oxidative stress publications published
between 1991 and 2010 in journals of all the subject categories of the Science citation index. Publication trends were analyzed
by the retrieved results in publication type and language, characteristics of articles outputs, country, subject categories
and journals, and the frequency of title-words and keywords used. Over the years, there was a significant growth in article
outputs, with more countries participating and collaborating. The seven major industrialized countries (G7) published the
majority of the world articles while the USA contributed about one-third of the total. Chinese and Indian outputs grew much
faster than those of other countries in the past 5 years. Oxidative stress research in food and environmental related fields
gradually became the mainstream of the research. An analysis of the title-words, author keywords and keywords plus showed
that antioxidants in human or rat cells were the hot topic in the field. In addition, “reaction oxygen species”, “apoptosis”,
and “nitric-oxide” were major topics of oxidative stress research recently. More articles dealt with diseases that had a strong
relationship with oxidative stress, such as inflammation, Alzheimer’s disease, diabetes, and atherosclerosis. 相似文献

The paper deals with a scientometric analysis of publications from the journals “Ecology” and “Ecologia” (Russia) based on
the frequencies of individual and cojoint encountering of ecological and mathematical keywords in these publications. Two
main research approaches are revealed: population ecology and system ecology. The first one is used primarily in studies of
plant communities, while the other in terrestrial animals and birds. Water communities are the subject of both approaches.
The most spread mathematical methods are the methods of mathematical statistics which can be clustered into four groups: standard
ones, multivariate methods, in particular multiple regression and multivariate analysis of variance, nonparametric or allowing
deviations from normality, and methods of analysis of categorical data. Differential equations and stochastic process are
used much lesser. The intensities of using mathematical methods are notably different in two journals.
This paper (originally published in Russian in The Journal of General Biology) was inspired, like many others, by Professor
V. V. Nalimov, and he contributed much in fruitful discussion and advices. 相似文献

This article proposed a new index, so-called “Article-Count Impact Factor” (ACIF) for evaluating journal quality in light
of citation behaviour in comparison with the ISI journal impact factors. The ACIF index was the ratio of the number of articles
that were cited in the current year to the source items published in that journal during the previous two years. In this work,
we used 171 journal titles in materials categories published in the years of 2001–2004 in international journals indexed in
the Science Citation Index Expanded (SCI) database as data source. It was found that ACIF index could be used as an alternative
tool in assessing the journal quality, particularly in the case where the assessed journals had the same (equal or similar)
JIF values. The experimental results suggested that the higher the ACIF value, the more the number of articles being cited.
The changes in ACIF values were more dependent on the JIF values rather than the total number of articles. Polymer Science
had the greatest ACIF values, suggesting that the articles in Polymer Science had greater “citation per article” than those in Metallurgical Engineering and Ceramics. It was also suggested that in order to increase a JIF value of 1.000,
Ceramics category required more articles to be cited as compared to Metallurgical Engineering and Polymer Science categories. 相似文献

A comparative study of research performance in computer science 总被引:4,自引:5,他引:4
The paper compares the research performance in computer science of four major Western countries, India and China, based on
the data abstracted from INSPEC database during the period 1993–2002. A total of 9,632 computer science papers recorded in
INSPEC database were used for the comparison. The findings indicate that, on the one hand, the number of papers produced in
China has considerably increased in the past few years. Particularly, in recent years, China occupies a remarkable high position
in terms of counts of papers indexed by the INSPEC database. On the other hand, Chinese scientists preferred to publish in
domestic journals and proceedings and shares of SCI-papers to the total journal papers for China have still remained the lowest.
This indicates that the research activities of Chinese scientists in computer science are still rather “local” and suffer
from a low international visibility. Various scientometric indicators, such as Normalized Impact Factor, ratio of papers in
high quality journals are further adopted to analyze research performance and diverse finding are obtained. Nevertheless,
for these surrogate indicators, China has optimistically achieved great progress, characterized with “low level of beginning
and high speed of developing”. The policy implication of the findings lies in that China, as well as other less developed
countries in science, can earn relative competitive advantages in some new emerging or younger disciplines such as computer
science by properly using catch-up strategy.

A correlation between the peculiarities of the electric permittivity (EP) ɛ(q, ω) of a homogenous and isotropic Coulomb system (CS) in the limit of ω → 0, q → 0 and q → 0, ω → 0 is established on the basis of exact limiting relations; general expression for static EP ɛ(q, 0) of a CS is obtained in the region of small wave vectors q. The concepts of a “true” dielectric and “ideal” conductor are introduced. The definition of a “true” screening radius is
considered. A critical point of two-component CS is shown to correspond to either the “true” dielectric state or the “ideal”
conductor one. 相似文献
