The Relationship

AbstractUnderstanding the nature and value of scientific collaboration is essential for sound management and proactive research policies. One component of collaboration is the composition and diversity of contributing authors. This study explores how ethnic diversity in scientific collaboration affects scientific impact, by presenting a conceptual model to connect ethnic diversity, based on author names, with scientific impact, assuming novelty and audience diversity as mediators. The model also controls for affiliated country diversity and affiliated country size. Using path modeling, we apply the model to the Web of Science subject categories Nanoscience & Nanotechnology, Ecology and Information Science & Library. For all three subject categories, and regardless of if control variables are considered or not, we find a weak positive relationship between ethnic diversity and scientific impact. The relationship is weaker, however, when control variables are included. For all three fields, the mediated effect through audience diversity is substantially stronger than the mediated effect through novelty in the relationship, and the former effect is much stronger than the direct effect between the ethnic diversity and scientific impact. Our findings further suggest that ethnic diversity is more associated with short-term scientific impact compared to long-term scientific impact.

The paper analyzed the global growth and development of flipped classroom research productivity in terms of publication output as reflected in SCI/SSCI for the period 2000-2015. Publication types and languages, characteristics of articles outputs, countries, subject categories and journals, and the frequency of keywords were analyzed using bibliometric methods. There are 149 articles in 78 journals listed in 41 SCI/SSCI subject categories. A sharp growth trend of publication output was observed during 2011-2015. USA played a predominant role in flipped classroom research. Education educational research, chemistry and medical were the top 3 categories and “active learning” and “blended learning” recent major topics of flipped classroom research during the past 16 years. The results could help researchers understand the characteristics of research output and search hot spots of flipped education field.

A bibliometric survey of the Himalaya-Karakoram-Hindukush-Tibet (HKHT) region, the largest mountain system on Earth, for research publications recorded in the Web of Science (WOS) during 1901-2018 revealed 46,746 citable documents (articles, reviews, letters and notes) showing exponential growth mainly after 1980s. The HKHT publications that cover 244 WOS subject categories (SCs) have been used to determine the relative shares by HKHT units, countries, research organizations and publication sources. Nine WOS SCs related to “earth, environmental and agricultural sciences” exhibit highest shares (22.6% to 3.2% of the total) by the whole counting method. Further analysis of the 1994-2018 subset related to 4 broader disciplinary classes (Geosciences, Environmental Sciences & Technologies, Agricultural Sciences, and Ecological Sciences) attributed to “field sciences” with particular emphasis on the high impact (TOP10% globally by citation) documents enables to capture the most prolific, representative (both in space and time) and impactful research. This study identifies the prolific countries, institutions, journals, etc. characterizing the cross-disciplinary research transcending national boundaries and involving international teams. Science mapping of high impact publications (4,561 documents) using the co-occurrence of keywords restricted to noun phrases reveals six prominent clusters that reflect the prolific and high impact research themes in field science for the whole HKHT region: five of them related to earth and environmental sciences (climate change including monsoon regime, tectonic evolution of the Himalaya-Tibet orogen, India-Asia collision and associated crustal phenomena, activities on major thrusts, channel flows and inverted metamorphism), and one contrasting theme concerning the genetic diversity of plants mainly of medicinal values.
