Aim The International Endodontic Journal (IEJ) has served as a platform for research and clinical practice in Endodontics since 1967. This study provides a bibliographic analysis and overview of the publications that have appeared in the IEJ from 1967 to 2020. Methodology A literature search was performed in Elsevier's Scopus database to locate all the publications of the International Endodontic Journal. Various bibliometric software packages including the open‐source visualization software Gephi and Biblioshiny (version 2.0) were employed for data visualization and analysis. Results A total of 3739 records with citation and bibliographic details were selected and retrieved to allow a bibliometric analysis to be performed. The bibliometric analysis indicates that the IEJ has grown both in terms of productivity and influence. Over time, the journal has been associated with an increase in the number of manuscripts published and the citations they have attracted, but with minor downward fluctuations in citations in the last few years. Bibliographic coupling of the IEJ articles revealed that the major research themes published in the journal include ‘endodontics’, ‘root canal treatment’, ‘calcium hydroxide’, ‘apical periodontitis’, ‘mineral trioxide aggregate’, ‘microbiology’, ‘cyclic fatigue’, ‘cone‐beam computed tomography’ and ‘micro‐computed tomography’. Authors affiliated to institutions in the UK were the major contributors to the journal and were linked with other countries such as Brazil, USA and Malaysia. The largest number of publications were from the University of São Paulo, Brazil. Conclusion The IEJ is one of the leading journals in Endodontology and has been providing a platform for innovative research and clinical reports for more than 50 years. Publications have been associated with a wide range of authors, institutions and countries around the world.

Water deficit stress negatively affects wheat growth, physiology, and yield. In lab and hydroponic experiments, osmotic stress levels (control, −2, −4, −6 and −8 Bars) created by PEG-6000, caused a significant decline in germination, mean germination time, root, shoot, and coleoptile length in both wheat genotypes examined. Germination was inhibited more in Wafaq-2001 than in Chakwal-50. Wafaq-2001 showed a higher susceptibility index based on root and shoot dry weight than did Chakwal-50. Wheat plants exhibited osmotic adjustment through the accumulation of proline, soluble sugars, soluble proteins, and free amino acids, and increased antioxidation activities of superoxide dismutase, peroxidase, catalase, and malondialdehyde. Increasing water deficit stress caused a linear decline in chlorophyll contents, leaf membrane stability, and relative water content in all wheat plants, with Wafaq-2001 showing a more severe negative impact on these parameters with increasing stress levels. The results suggest the possibility of utilizing some of these parameters as quantitative indicators of water stress tolerance in plants. Gas exchange measurements (photosynthesis, transpiration, stomatal conductance), leaf osmotic potential, water potential, and yield attributes decreased more abruptly with increasing water deficit, whereas leaf cuticular wax content increased in both genotypes, with more severe impacts on Wagaq-2001. More reduction in biochemical, physiological, and yield attributes was observed in Wafaq-2001 than was observed in Chakwal-50. Based on these results, we can conclude that Chakwal-50 is a more drought-tolerant genotype, and has excellent potential for future use in breeding programs to improve wheat drought tolerance.

Self-disclosure on social networking sites (SNSs) leads to social capital development, connectedness, and relationship building. Due to several benefits associated with this behavior, self-disclosure has become a subject of research over the last few years. The current study investigates the antecedents of self-disclosure under the lens of the technology acceptance model (TAM). The research is quantitative, and the data were collected from 400 Pakistani Facebook users with a variety of demographic characteristics. The partial least squares-structural equation model (PLS-SEM) analysis technique was employed to analyze the data. The study′s findings confirmed that perceived usefulness is a strong predictor of personal information sharing, and it along with other variables causes a 31% variation in self-disclosure behavior. However, trust (medium and social) mediates the relationshipof perceived usefulness, privacy concerns, and self-disclosure behavior.

Research discovers new knowledge, ideas, and technologies essential in driving the future of society and humanity. Without research, a relevant and modern country cannot exist. Similarly, the research output of universities and degree-awarding institutes (DAIs) plays a significant role in higher education and development of any country. Research fosters professional excellence in faculty, important for delivering outstanding student education and training. Therefore, this research is an evaluation of the research output of higher education DAIs in the capital of Pakistan. This research was conducted in four steps: (a) data collection: where the data were extracted from Scopus for the years 2008–2017; (b) data cleansing and labeling: which included removal of nonrequired contents and labeling of nonnumeric data to meaningful classes; (c) feature selection: useful features according to proposed research questions were selected; and (d) data analysis: data were analyzed according to research questions and results obtained from experiments with the help of statistical tools. It is concluded that with only 1% of country’s population and around 11% of Higher Education Commission’s (HEC) recognized universities geographically located at Islamabad Capital Territory, Islamabad-based universities and DAIs contributed 34% of the total publications of Pakistan produced during the study time period. This shows Islamabad-based universities and DAIs standing at the national level. The public sector universities shared the major portion of total publications of the studied universities. Private sector universities and DAIs shared 8% of the total publications.

Bibliometric methods are used to access various elements in any data set. Similarly, this study uses a bibliometric method to evaluate the research performance of the University of the Punjab (PU), the oldest university of Pakistan. A peer university from a neighboring country, India, has been selected in this study along with three state-owned universities of Pakistan. The research yield of selected universities was analyzed since their establishment until 2019. The data were retrieved from the Scopus database in February 2020. The guidelines of the Carnegie Classification of Institutions of Higher Education were used to select the peer universities. It has been analyzed that steady progress in research productivity was observed during the 20th century and in the last few years of the 19th century. A focus shift was observed with the onset of the 21st century and a rapid increase in research publications was observed in Pakistani universities. Around 92% of research studies of the University of the Punjab were carried out during the first 20 years of the 21st century and it leads the compared peer universities in terms of the number of research publications and the citations. It is also analyzed that there is a tendency among the authors of studied universities to publish their research articles in subscription-based journals. The authors affiliated with the University of the Punjab are more inclined to publish their research in open access journals as compared to the researchers of other studied universities. It is also observed that publications with single authors received a low average of citations per document while the publications with six or more authors had the highest average citations. The study recommends collaborative efforts for carrying out research and publication in open access journals is encouraged because of greater visibility, access, and impact.
