Discipline Impact Factor: Some of Its History, Some of the Author’s Experience of Its Application, the Continuing Reasons for Its Use and… Next Beyond
Purpose: This work aims to consider the role and some of the 42-year history of the discipline impact factor (DIF) in evaluation of serial publications. Also, the original “symmetric” indicator called the “discipline susceptibility factor” is to be presented. Design/methodology/approach: In accordance with the purpose of the work, the methods are analytical interpretation of the scientific literature related to this problem as well as
speculative explanations. The information base of the research is bibliometric publications dealing with impact, impact factor, discipline impact factor, and discipline susceptibility factor.
Findings: Examples of the DIF application and modification of the indicator are given. It is shown why research and university libraries need to use the DIF to evaluate serials in conditions of scarce funding for subscription to serial publications, even if open access is available. The role of the DIF for evaluating journals by authors of scientific papers when choosing a good and right journal for submitting a paper is also briefly discussed. An original indicator “symmetrical” to the DIF (the “discipline susceptibility factor”) and its differences from the DIF in terms of content and purpose of evaluation are also briefly presented.
Research limitations: The selection of publications for the information base of the research did not include those in which the DIF was only mentioned, used partially or not for its original purpose. Restrictions on the length of the article to be submitted in this special issue
of the JDIS also caused exclusion even a number of completely relevant publications. Consideration of the DIF is not placed in the context of describing other derivatives from the Garfield impact factor.
Practical implications: An underrated bibliometric indicator, viz. the discipline impact factor is being promoted for the practical application. An original indicator “symmetrical” to DIF has been proposed in order of searching serial publications representing the external research
fields that might fit for potential applications of the results of scientific activities obtained within the framework of the specific research field represented by the cited specialized journals. Both can be useful in research and university libraries in their endeavors to improve
scientific information services. Also, both can be used for evaluating journals by authors of scientific papers when choosing a journal to submit a paper.
Originality/value: The article substantiates the need to evaluate scientific serial publications in library activities—even in conditions of access to huge and convenient databases (subscription packages) and open access to a large number of serial publications. It gives a mini-survey of the history of one of the methods of such evaluation, and offers an original method for evaluating scientific serial publications
On One of the Possible Formation Mechanisms of Narrow Sporadic Ionosphere Layers
Electron density, and sounding rocket investigation of narrow sporadic ionosphere layer
Automatic processing system for shadowgraph and interference patterns
The design and operation of an automatic system for the processing of shadowgraph and interference images are described. The system includes a two-coordinate processing table with an optical system for the projection of transparent images onto the photodetector, an image filter in the photodetector field, and a device for controlling the movement of the table and transmitting information to the minicomputer
Formation of non-state pension system in the Russian Federation on an example of the activities of non-state pension fund "Sberbank"
The article is devoted to a problem, which is important relevant for the Russian Federation.it is studying the factors of formation of non-state system in provision of pensions.
In this article, the authors have described the russian specifics of formation in the system of non-state pension provision in the Russian Federation. As the main methods, the system and structural and analytical analysis are chosen. Data and materials of the non-state pension fund of Sberbank became material of a research.
The main documents regulating formations and functioning of the non-state pension funds are submitted. It is shown that one of the most perspective is activity of the non-state pension fund of Sberbank.
The sources of formation of revenues of the non-state pension fund of Sberbank are described. Both individual and corporate programs of the non-state pension fund of Sberbank are submitted.
The conducted research allows making conclusions that despite the undertaken reforms of provision of pensions by the citizens.peer-reviewe
Coherent lidars based on intracavity heterodyning of echo signals
The development and technical realization of the method of laser sounding of the atmosphere based on the effects of mixing of reference and external fields of scattering inside a laser cavity are presented. An approximate theory of the method was developed on the basis of the investigations using the model of a three-mirror laser. The nonlinear effect of a wideband laser on frequency-dependent external influences of the atmosphere was investigated. The field measurements of gaseous composition of the atmosphere were performed on the basis of a given method of coherent reception using a tunable CO2 laser
Combinatorics and formal geometry of the master equation
We give a general treatment of the master equation in homotopy algebras and
describe the operads and formal differential geometric objects governing the
corresponding algebraic structures. We show that the notion of Maurer-Cartan
twisting is encoded in certain automorphisms of these universal objects
