Information Metrics (iMetrics): A Research Specialty with a Socio-Cognitive Identity?
"Bibliometrics", "scientometrics", "informetrics", and "webometrics" can all
be considered as manifestations of a single research area with similar
objectives and methods, which we call "information metrics" or iMetrics. This
study explores the cognitive and social distinctness of iMetrics with respect
to the general information science (IS), focusing on a core of researchers,
shared vocabulary and literature/knowledge base. Our analysis investigates the
similarities and differences between four document sets. The document sets are
drawn from three core journals for iMetrics research (Scientometrics, Journal
of the American Society for Information Science and Technology, and Journal of
Informetrics). We split JASIST into document sets containing iMetrics and
general IS articles. The volume of publications in this representation of the
specialty has increased rapidly during the last decade. A core of researchers
that predominantly focus on iMetrics topics can thus be identified. This core
group has developed a shared vocabulary as exhibited in high similarity of
title words and one that shares a knowledge base. The research front of this
field moves faster than the research front of information science in general,
bringing it closer to Price's dream.Comment: Accepted for publication in Scientometric
Citations: Indicators of Quality? The Impact Fallacy
We argue that citation is a composed indicator: short-term citations can be
considered as currency at the research front, whereas long-term citations can
contribute to the codification of knowledge claims into concept symbols.
Knowledge claims at the research front are more likely to be transitory and are
therefore problematic as indicators of quality. Citation impact studies focus
on short-term citation, and therefore tend to measure not epistemic quality,
but involvement in current discourses in which contributions are positioned by
referencing. We explore this argument using three case studies: (1) citations
of the journal Soziale Welt as an example of a venue that tends not to publish
papers at a research front, unlike, for example, JACS; (2) Robert Merton as a
concept symbol across theories of citation; and (3) the Multi-RPYS
("Multi-Referenced Publication Year Spectroscopy") of the journals
Scientometrics, Gene, and Soziale Welt. We show empirically that the
measurement of "quality" in terms of citations can further be qualified:
short-term citation currency at the research front can be distinguished from
longer-term processes of incorporation and codification of knowledge claims
into bodies of knowledge. The recently introduced Multi-RPYS can be used to
distinguish between short-term and long-term impacts.Comment: accepted for publication in Frontiers in Research Metrics and

Income Inequality and Social Policy in Serbia
Using 2006-2009 HBS data, we study poverty and inequality in Serbia and compare income-group impacts of different social policy programmes. Methodological innovations of the paper are: testing validity of OECD equivalence scale by HAC procedure and replacing it with per capita measurements, use of quantile regression and recursive estimation in defining income groups with specific responses, and testing group effects (partitioned coefficients) of policy programmes in the frame of panel methodology. The confirmed hypotheses are: income inequality is decreasing as a consequence of social policy measures, except for in the last observed year, but these effects vary in different income-groups.inequality, transition, social policy, Serbia, quantile regression, panel model
Energijska analiza teorijskog Braytonova desnokretnog procesa
Cilj ovog rada je energijska analiza teorijskog Braytonov desnokretnog procesa.U poÄetku rada napisan je kratki osvrt na povijest mlaznih motora.Nakon povijesti su opisani glavni dijelovi mlaznih motora i karakteristiÄne njihove podjele.

Katalogizacija i klasifikacija u Sjedinjenim AmeriÄkim Državama
In the Paper are treated the Principles and the Implementation of the Cataloguization and Classification in USA, with a special overview on modern streams. The main goal of the organization of Library Holdings is the satisfaction of different Userās needs for Information. The organization of Knowledge in the Libraries implies the organization of several different types of information and media. In the Paper are described the Anglo-American Rules for Cataloguization and MARC, as standards for the alphabetical Cataloguization. As well the influence of the cooperative cataloguization and the usage of computer technology within the development of these Standards. One can find also a brief description of Dewey Decimal Classification (DDC) and the Classification of the Congress Library in Washington D.C, as the two dominating classificational Systems. Followed by the description of the controled dictionnaries, with special overview on Subject Heading of the Congress Library. The Paper treats also the Problem of Information on the Internet, as well proliferation of the Material in electronic format, which requires the incorporation in traditional library Catalogues
Re-Conceptualization of the Idea of Neighborhood in Post-Socialist Belgrade
Understanding the concept of collective form is of particular
interest for re-conceptualization of the idea of neighborhood
in post-socialist Belgrade. After the experiences of the socialist
community, Belgrade is facing the issue of social atomization
and numerous manifestations of the culture of distrust. These
conditions in which the duties towards the others are not
recognized for the sake of oneās own sustain Thomas Hobbes
defines as an issue of the wrong reason. In the region of Serbia
the problem of wrong reason has its own history. Its fragments
are found in the modern urbanization of the cities in Serbia, at the
neighborhood level ā shaped by the tension between the power
directives and the desire of the ordinary people. According to
the principle of reciprocity, based on the criteria of functional
orientation, attractiveness and connectivity of group form
elements, considering the presence of the culture of distrust,
the intention of this article is to initiate discussion on proposed
terminology and to reveal the key points for transformation of
the dwelling community concept into neihgborhood concept
TEMPORARY MEASURES IN CRIMINAL PROCEEDINGS AGAINST JUVENILES
he specific nature of juvenile delinquency and the all-present tendency of diverse response to juvenile crime have resulted in distinguishing juvenile criminal law as a separate branch of criminal law. Juvenile criminal law entails special temporary measures which, as such, do not exist in the proceedings against adult individuals. In this paper, the author will point out their characteristics and analyse the concepts of temporary accommodation and referral of juveniles to professional institutions for further assessment. The paper also provides an explanation of the extent to which the international standards on juveniles are observed in our legislation in terms of these temporary measures. The adoption and subsequent application of the Act on Juvenile Criminal Offenders and Protection of Minors in Criminal Law (hereinafter: the Juvenile Justice Act) has proven to be a positive turning point in the regulation of temporary measures. Thus, there is no need for significant reforms except for slight changes, which will be pointed out in this paper. The new draft of the Juvenile Justice Act does not bring substantial changes in this area. This paper provides an overview of the amended provisions and analyzes their purpose and implications
Towards a more realistic citation model: The key role of research team sizes
We propose a new citation model which builds on the existing models that
explicitly or implicitly include "direct" and "indirect" (learning about a
cited paper's existence from references in another paper) citation mechanisms.
Our model departs from the usual, unrealistic assumption of uniform probability
of direct citation, in which initial differences in citation arise purely
randomly. Instead, we demonstrate that a two-mechanism model in which the
probability of direct citation is proportional to the number of authors on a
paper (team size) is able to reproduce the empirical citation distributions of
articles published in the field of astronomy remarkably well, and at different
points in time. Interpretation of our model is that the intrinsic citation
capacity, and hence the initial visibility of a paper, will be enhanced when
more people are intimately familiar with some work, favoring papers from larger
teams. While the intrinsic citation capacity cannot depend only on the team
size, our model demonstrates that it must be to some degree correlated with it,
and distributed in a similar way, i.e., having a power-law tail. Consequently,
our team-size model qualitatively explains the existence of a correlation
between the number of citations and the number of authors on a paper.Comment: Published in journal Entropy. Open access article available at
