Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
CEO/board medical background and stock returns during the COVID-19 pandemic
No full textThe study investigates the impact of the CEO/board medical background on stock return reactions to COVID-19. CEOs/boards having a medical background possess a knowledge advantage, which enables them to identify risks earlier, take faster action and better prepare for business operations in response to pandemic shocks. Using data from China between January 1st and March 31st, 2020, we find that firms with CEOs or board members having medical background experienced a less severe pandemic-related decline in stock returns. This effect is more evident for firms having a powerful CEO, with more medical directors and located in cities with fewer medical resources. Better operating performance and more investment activities are underlying mechanisms that result in the outperformance of firms with medical expertise. Overall, our findings highlight the critical role of the expertise and experiences of senior executives in shaping the responses to adverse events
Environmental Regulation and Corporate R&D Investment—Evidence from a Quasi-Natural Experiment
No full textThe question of whether environmental regulation stimulates innovation activities has long been important and controversial. This study explores an ideal setting, the low-carbon city pilot program conducted by the Chinese government as a quasi-natural experiment to address this question. We conduct a difference-in-differences approach to analyze the impact of environment regulation on R&D investment. We find that the program's adoption has led to an increase in R&D investment of 0.145% as a percentage of total assets and 0.273% as a percentage of sales, indicating a positive effect of environmental regulation on R&D expenditures. The increase in R&D expenditures is greater for firms experiencing a larger increase in government subsidies, a greater decline in corporate tax or a greater improvement in financial condition following the low-carbon pilot program. A series of robustness tests support a causal interpretation of our findings and indicate that the observed effect of the low-carbon pilot program on corporate R&D investment is unlikely driven by chance. Our results provide in-depth insights into the economic consequences of low-carbon regulation policies which could be of interest to academic researchers and policymakers

Chao Yuen Ren (1892–1982)
No full textY. R. Chao is easily the most famous linguist to have come out of China. Born before the end of the last dynasty in China, he received a traditional Confucian education, but was also one of the first Chinese people to be sent to the West for training in modern Western science (under the Boxer Indemnity Fund). The remarkable breadth and scope of his studies included physics, mathematics, linguistics, musical and literary composition, and translation, and he was a pioneer in many of these fields
Low-carbon city initiatives and firm risk: A quasi-natural experiment in China
No full textThis study contributes to the low-carbon city (LCC) related literature by providing causal evidence on the impact of carbon reduction regulation on firm risk. Using staggered adoption of LCC program shocks in China as a quasi-natural experiment, we implement a difference-in-differences (DiD) analysis to investigate the impact of the low-carbon city initiatives on firm risk. We find that low-carbon city initiatives are significantly correlated with firm total risk, systematic risk, and idiosyncratic risk. The results are more pronounced for firms with greater changes of investment in fixed assets and R&D and for firms in provinces with stronger legal enforcement. Our study provides in-depth insights into the low-carbon city initiatives and the firm-level impact of its implementation
