Introduction: This study presents a global research scenario in the broad domain of osteoarthritis (OA) research, using quantitative and qualitative publication and citation indicators. Methods: The study is based on 45,368 global publications, sourced from the Scopus bibliographical database, covering three decades (1994–2023). We studied the performance of the top 12 developed and top 12 developing countries. The key countries, organizations and authors at national and international levels were identified. The broad subject areas and key journals contributing to global OA research were delineated, besides identifying the broad characteristics of highly cited papers in the field. Results: The United States and China were the most productive countries, while the Netherlands and Canada made the largest citation impact. Harvard Medical School and the University of Sydney made the most contribution, while Boston University and Pfizer Inc., USA registered the highest citation impact. Hunter DJ and Guermazi A were the most productive authors, while Lohmander LS, and Hochberg MC registered the highest citation impact. Osteoarthritis and Cartilage (n = 4879) and Annals of the Rheumatic Diseases (n = 786) published the maximum papers, while Arthritis and Rheumatism and Nature Reviews Rheumatology registered the largest citation impact. The highly cited papers with 100 or more citations constituted 6.25% of the total publications. Conclusions: There has been a systematic growth of publications on OA. The research on OA was mainly done in developed countries, with the maximum publications coming from the United States of America, China and Canada. The most impactful publications on OA were from the Netherlands, Canada and the United States of America. [ABSTRACT FROM AUTHOR]

We examine the real convergence hypothesis for 14 OECD countries looking at the fractional order of integration of the differences of real GDP per capita in these countries with respect to the United States. Using parametric procedures, the results vary depending on how we specify the I(0) disturbances. If they are white noise, convergence is achieved for Canada and Australia, and with autocorrelated disturbances, this hypothesis is satisfied for France and the Netherlands. However, allowing for a break at World War 11, evidence of convergence is obtained for all countries. [ABSTRACT FROM AUTHOR]

Our aim is to enhance the knowledge regarding how the public assess and rate volunteerism. We begin by first developing the model for understanding the potential use of the net-cost concept in eliciting the public's subjective perceptions on the extent to which certain activities are perceived as volunteerism. Four hypotheses relevant to the use of the net-cost concept are developed. We developed a questionnaire consisting of 50 case scenarios and applied it in Canada, India, Italy, Netherlands, and Georgia and Philadelphia in the United States, each with a sample of 450 adults or more. With one exception, our net-cost hypotheses are supported, suggesting that the public perception of volunteering is strongly linked with the costs and benefits that accrue to the individual from the volunteering activity, and that this result holds true across different cultures. Finally, we suggest directions for future research that can shed further light on the relationship between net cost and public good. [ABSTRACT FROM AUTHOR]
