The present study aims to determine the prevailing trend of self-citations across 27 major subject disciplines at global level. The study also examines the aspects like percentage of self-citations in each individual subject discipline and the average number of self-citations per publication across different subject disciplines. The study also investigates self-citation percentage of research articles published from the 20 leading research countries of the world and across the continents.

The study is supported by empirical findings undertaken on secondary data retrieved from SCImago Journal and Country Ranking, which is entirely based on the SCOPUS data source (SCImago, 2014).

In all, 76,634,557 citations were received by as many as 14,946,975 research articles published from 2008-2012 at an average of 5.12 citations per article. Of the total citations received, 26,404,609 (34.45 per cent) were self-citations, which means that of the total citations received by each research article, 1.76 are self-citations. Compared to subject disciplines falling under social and humanistic sciences, pure and applied sciences have shown a greater trend of self-citation. On average, 4.18 self-citations were observed in each research article published in multidisciplinary subject disciplines. Of the total citations received by research articles published in the discipline of Psychology, 43.69 per cent are self-citations, the highest among all the subject disciplines under study. Of the total self-citations received by all the subject disciplines under study, 18.43 per cent were received alone in medicine, highest among all, whereas Social and Humanistic sciences received less than 1.00 per cent self-citations, the lowest among all the subject disciplines.

This study is original and first of its kind covering each individual subject discipline having global scope.

This study aims to find out the average journal packing density (JPD) of Library and Information Science (LIS) research journals published across the world. The concept, JPD, means the average number of research articles published by a research journal in one volume. Accordingly, the undergoing study evaluates the average number of research articles published in each volume of each research journal published in the field of LIS at the global level. Some other key aspects evaluated include the number of LIS research journal publishing countries, average JPD of LIS research journals at the continental level, etc.

This study is purely based on secondary data retrieved from SCImago, which is SCOPUS data. Keeping in view the objectives of this study, the data about research articles published in all LIS research journals during the period 2015 through 2019 were retrieved to undertake the study.

From the data analysis, it emerged that 256 research journals duly indexed by SCOPUS are published in the field of LIS across 36 countries. In all 48,596 research articles were published from 2015 to 2019 in these research journals at an average of 44.71 research articles per journal per volume. More than 75% of LIS research journals are published from Germany, Spain, Netherlands, the USA and the UK. Research journals published from the USA have higher JPD of 53.09 research articles per journal per volume, which is 18.74% higher than the average global JPD of LIS research journals. 50% of LIS research journal publishing countries are from Europe and the majority 52.55% LIS research articles were published in European LIS research journals. The average JPD of LIS research journals published from North America is 51.73 research articles per journal per volume, which is the highest across continents.

Standardization of JPD of research journals irrespective of the subject discipline they are published in is important for many reasons and the foremost being, such standardization helps in keeping at bay the predatory research journals, which normally float such packing density norms, with the sole aim to earn money in the shape of manuscript handling charges, thereby publishing a far greater number of research article in each issue of a journal than the average research articles published by a research journal.

Very few studies have been conducted around the concept JPD, especially by the authors of this particular study. This study has however been particularized to the LIS subject discipline, while the findings add to existing lot of study already undertaken, hence outcome can be generalized.

The purpose of this paper is to investigate the effect of the replacement of natural coarse aggregate (NCA) with different percentages of recycled coarse aggregate (RCA) on properties of low calcium fly ash (FA)-based geopolymer concrete (GPC) cured at oven temperature. Further, this paper aims to study the effect of partial replacement of FA by ground granulated blast slag (GGBS) in GPC made with both NCA and RCA cured under ambient temperature curing.

M25 grade of ordinary Portland cement (OPC) concrete was designed according to IS: 10262-2019 with 100% NCA as control concrete. Since no standard guidelines are available in the literature for GPC, the same mix proportion was adopted for the GPC by replacing the OPC with 100% FA and W/C ratio by alkalinity/binder ratio. All FA-based GPC mixes were prepared with 12 M of sodium hydroxide (NaOH) and an alkalinity ratio, i.e. sodium hydroxide to sodium silicate (NaOH:Na₂SiO₃) of 1:1.5, subjected to 90^°C temperature for 48 h of curing. The NCA were replaced with 50% and 100% RCA in both OPC and GPC mixes. Further, FA was partially replaced with 15% GGBS in GPC made with the above percentages of NCA and RCA, and they were given ambient temperature curing with the same molarity of NaOH and alkalinity ratio.

The workability, compressive strength, split tensile strength, flexural strength, water absorption, density, volume of voids and rebound hammer value of all the mixes were studied. Further, the relationship between compressive strength and other mechanical properties of GPC mixes were established and compared with the well-established relationships available for conventional concrete. From the experimental results, it is found that the compressive strength of GPC under ambient curing condition at 28 days with 100% NCA, 50% RCA and 100% RCA were, respectively, 14.8%, 12.85% and 17.76% higher than those of OPC concrete. Further, it is found that 85% FA and 15% GGBS-based GPC with RCA under ambient curing shown superior performance than OPC concrete and FA-based GPC cured under oven curing.

The scope of the present paper is limited to replace the FA by 15% GGBS. Further, only 50% and 100% RCA are used in place of natural aggregate. However, in future study, the replacement of FA by different amounts of GGBS (20%, 25%, 30% and 35%) may be tried to decide the optimum utilisation of GGBS so that the applications of GPC can be widely used in cast in situ applications, i.e. under ambient curing condition. Further, in the present study, the natural aggregate is replaced with only 50% and 100% RCA in GPC. However, further investigations may be carried out by considering different percentages between 50 and 100 with the optimum compositions of FA and GGBS to enhance the use of RCA in GPC applications. The present study is further limited to only the mechanical properties and a few other properties of GPC. For wider use of GPC under ambient curing conditions, the structural performance of GPC needs to be understood. Therefore, the structural performance of GPC subjected to different loadings under ambient curing with RCA to be investigated in future study.

The replacement percentage of natural aggregate by RCA may be further enhanced to 50% in GPC under ambient curing condition without compromising on the mechanical properties of concrete. This may be a good alternative for OPC and natural aggregate to reduce pollution and leads sustainability in the construction.

This study aims to seek the causative relationship between the library budget and research output with the ranking of 20 leading medial institutes in India. More so, the study also attempts to find out whether the libraries associated with academic and research institutes in general and medical institutes in particular have turned redundant or irrelevant, or have become more relevant in the changing times by embracing technology in its every new form.

The study is based on the secondary data retrieved from the official website of the Ministry of Education, Government of India and research output against each institution under study has been retrieved from Scopus. The study is limited to Indian medical institutions that participated in the 2019 National Institutional Ranking Framework (NIRF), conducted by the Ministry of Education, India each year. The findings of the study can be generalized to all the medical institutions of the country.

On average, INR 160.90m were spent by each medical institute on the procurement of library resources at an average of INR 0.104m on procurement of resources against each individual published research article. Of the total research articles published by medical institutes under study, 26.39% of research articles were published by researchers from AIIMS, New Delhi, alone.

Financial aid or funding is very vital for the survival, sustenance and excellence of research institutions, and this funding becomes more important when the investigation is aimed toward the furtherance of medical advances. Any medical advancement is hell-bent to influence the overall welfare and betterment of society at large, whereby the benefit of any investment made in medical science is bound to be reaped by one and all alike.

In India, a good number of studies have been undertaken on the NIRF data to dive deeper to assess the role and importance of libraries in the overall ranking of institutions like universities, management institutes, engineering and technology institutes, but no major study has been so far conducted covering leading medical institutes in India. The study is the original and first of its kind undertaken in India.

This study aims to assess the enrolment scenario of Library and Information Science (LIS) education in India offered through distance mode.

The scope of the study is limited to India, reflecting the trend of distance education in LIS in India. The study is based on the secondary data collected by the Ministry of Human Resource and Development, Government of India (GOI) under All India Survey on Higher Education (AISHE). It is to mention that Ministry of Human Resource and Development, GOI, is regularly collecting data from higher education institutions all across the country under AISHE project. The data in the study have been analysed for the period 2011 to 2018.

The findings of the study reveal that, of the total enrolments made in LIS education in India during the period 2011 to 2018, nearly one-fourth of students were enrolled through regular mode and three-fourth were enrolled through distance mode, signifying distance mode of education as the largest medium of LIS education in India. The enrolment figures through distance mode showed slight inconsistency with the result, a negative (−0.49%) average annual corresponding growth was recorded in the enrolment of LIS students through distance mode. Of the total students enrolled in different LIS programmes through distance mode during the period of study, the majority (67.78%) of students were enrolled in the Under Graduate programme (B.Lib.I.Sc.). Similarly, of the total students enrolled in LIS through distance mode during the period of study, 51.36% were female students and 48.63% male students. In terms of caste category, of the total students enrolled during the period of study, 10.12% belonged to the Scheduled Caste category, 4.7% to Scheduled Tribes category, 28.77% Other Backward Class and 56.08% to others, which include general category students as well.

Learning through distance education is a welcome step as long as the idea is to improve the society and to reach out to those who hitherto remained unreached. Sustainable means of enrolment and employability has to be the order of the day, mostly based on demand and supply principle.

This study is original and first of its kind covering enrolment of the students in LIS courses.

The study aims to assess the journal packing density (JPD) of the research journals published across different subject discipline at the global level. The concept of JPD is aimed to compute the average number of research articles published per volume or per issue of a research journal in any given subject discipline. The study also discusses about the leading research journals publishing countries and continents across the world and their average JPD. An attempt has also been made to identify the leading research counties having maximum JPD in any given subject discipline.

The study covers 27 major research subject disciplines widely popular all across the globe. To undertake the present study, data were retrieved from SCImago Journal and Country Ranking.

In all, 36,081 research journals were indexed by Scopus across 27 major subject disciplines at the global level till 2015. During the period 2013-2015, 11,023,122 research articles were published in 36,081 research journals across 27 major subject disciplines at the global level at an average of 101.84 research articles per journal per volume. This means the average JPD of the research journals at the global level is 101.84 research articles per journal per volume. Chemistry, physics and astronomy and multidisciplinary journals are the three leading subject disciplines to have the maximum JPD, namely, 266.66, 253.92 and 242.53 research articles per journal per volume. JPD of research journals published in the sciences is higher than the JPD of research journals published in the social sciences and humanities. Business, management and accounting, social sciences and arts and humanities are three subject disciplines having lowest JPD, namely, 44.26, 35.68 and 32.66 research articles per journal per volume, respectively. China, Ireland and The Netherlands recorded the highest average JPD in the research journals published from these counties, namely, 213.39, 178.44 and 135.31 research articles per journal per volume, respectively.

Countries from where a lesser number of research journals are indexed by the popular indexes, such as Scopus, Web of Science, etc., face greater pressure of publishing. To ooze out this pressure, there is need to index more and more research journals from these countries and that can be done only by improving and maintaining the research standard over a period.

The study is original and the first of its kind undertaken at the global level across all the major subject disciplines.

This study aims to find out the India’s research contribution to world Library and Information Science (LIS) literature from 2011 to 2020. Attempt has been made to reflect both the number of research articles published by the Indian LIS researchers during the past decade and the percentage share of Indian LIS researchers to the world LIS literature. Attempt has also been made to reflect the 20 leading LIS researchers from India, 20 leading LIS journals in which Indian LIS researchers mostly prefer to publish their research results and leading LIS research institutions and more.

The scope of the study is limited to library and information research undertaken across the world in general and India in particular during the past decade, viz., 2011–20. To undertake the present study, data were retrieved from SCOPUS data source. The data were retrieved keeping in view the objectives of the study; accordingly, key words were framed and used to search the relevant data.

Overall 77,659 research articles were published in the subject discipline of LIS across the world during the past decade, viz., 2011 through 2020. During the period of study, LIS researchers from India contributed 3,562 research articles constituting 4.59% of the total global LIS research output. The USA emerged the leading LIS research country with 33.03% research contribution, while India emerged as the fifth largest LIS research country in the world. A total of 12.85% research articles from India were contributed by 20 leading researchers. Only two LIS research journals from India were found indexed in the SCOPUS, in which 18.10% research articles were published by Indian LIS researchers during the period of study. More than 80% research results produced by Indian LIS researchers were published in foreign LIS research journals, mostly published from the USA and the UK. A good lot of Indian LIS researchers prefer to publish their research results in open access research journals. Library professionals, teachers and scholars from University of Delhi and University of Kashmir were found more active in LIS research in India.

India is one of the world’s popular LIS academic, research and practicing country and has more responsibility toward world LIS research, whereby India, apart from fulfilling its own LIS research requirements, has to meet out the global LIS research demand. Thereon, if it lacks on research front, which otherwise acts as a backbone in the survival of a subject discipline, the survival of subject discipline may become difficult.

India is one of the most progressive LIS research countries in the world and is about to play a far greater role in propagating newer and modern library practices and services in the years to come.

Quantification of research output at regional level or country level is very common among LIS professionals; accordingly, the existing study adds to existing world LIS literature about the India’s contribution to world LIS research during the past decade.

The purpose of this study is to reflect a growing trend toward the introduction of new research journals in India. The study focuses on the number of journals introduced in India during the past decade, namely, for the period 2005-2014. Some of the key aspects analyzed include year-wise distribution of journals introduced, cumulative and annual corresponding growth of newly introduced journals, publishing form of journals, namely, online, print and hybrid. Some other aspects studied include distribution of journals on the basis of language, periodicity, state, etc. for both online and print journals.

To undertake the present study, data were retrieved from the official website of the National Science Library, New Delhi, and the analysis is based on the number of ISSN numbers issued by the National Science Library New Delhi during the period of study.

A total of 15,631 research journals were introduced in India from 2005 through 2014. Compared to 4,954 (31.69 per cent) online journals, 10,614 (67.90 per cent) print journals were introduced in India during the past decade, depicting print as the larger medium of journal publishing in India. During the period of study, research journals in India grew annually at 31.44 per cent. New Delhi, Maharashtra and Uttar Pradesh emerged as the three leading research journal publishing states of the country, while 82.86 per cent journals are published in English language and a maximum 32.52 per cent journals are published on a quarterly basis.

The study is first of its kind undertaken in India.

The purpose of this paper is to examine the impact and role of libraries of the Institutes of Management in India in their research output. The study is based on the seven point performance evaluation parameter, whereby each individual library has been ranked on the basis of aggregate performance against each individual parameter. Some of the key parameters evaluated, include, preference of resource procurement namely, electronic or print, utilisation of library budget towards the procurement of print and electronic resources, average fund utilisation on resource procurement against each published research article and average fund utilisation on resource procurement against each faculty member. Research output against each faculty member and various other similar aspects have been evaluated.

The study is limited to the management institutes of India, but the findings can be generalised to assess omit it the overall trend across the management institutes in general and India in particular. The study is based on 2016 ranking list of Institutes of Management in India, compiled and released by the Ministry of Human Resource and Development, Govt. of India for the period 2012-2013, 2013-2014 and 2014-2015.

From the data analysis, it emerged that almost three-fourth of the library budget in the leading Management Institutes across India is being spent on the procurement of e-documents, mostly in the form of subscription of online journals. On average 1.18 research articles have been published by each faculty member during the period of study from each institute under study, with an average annual institutional research output of 19.63 research articles. In terms of resource allocation, on average Indian Rupees (INR) 0.986/million has been spent by each institutional library on the resource procurement against each published research article, and INR1.166/million has been spent on the resource procurement against each faculty member.

The study is an attempt to seek correlation between the money spend on the procurement of resources and its direct impact on the research output of that particular institution.

The study is original and first of its kind, undertaken in India.

The present study aims to assess the resource procurement preferences among the leading academic libraries of the institutes of higher learning across India. The study analyses the amount and percentage of budget spent by the institutions under study during the period 2012-2013, 2013-2014 and 2014-2015 on the procurement of print and electronic resources in their libraries. The study also discusses about concerns with regard to the subscription of e-resources and the reasons for weaning interest among the Indian academicians towards the print resources.

By and large, the scope of the study is limited to institutes of higher learning across India, but reflects a great deal of relevance to the global higher education practices. The study has been undertaken on the 20 leading institutes each from Universities, Institutes of Management and Institutes of Technology in India, based on the ranking list released by the Ministry of Human Resource Development, Government of India, on 4 April 2016.

The electronic documents are the dominant forms of present day library procurements in India, with the print struggling to retain its readership. The Institutes of Engineering and Technology and Management have almost similar procurement preferences, spending almost three-fourth of their library budgets on the procurement of e-documents. On average, the University libraries in India have spent 43.54 per cent of their budget on the procurement of print resources and 56.46 per cent of their budget on the procurement of electronic resources during the period of study. Similarly, on average, each Institute of Engineering and Technology has spent 24.04 per cent of their library budget on the procurement of print documents and 75.96 per cent towards the procurement of electronic resources, whereas 27.51 per cent of the library budget by the Institutes of Management in India is being spent on the procurement of print resources and 72.49 per cent towards the procurement of electronic resources.

The study is original and is first of its kind, undertaken on three different category of institutions, based on the national ranking of the country.
