Factors Affecting Turnover and Turnaway Intention of Journalists in South Korea

This study examined the factors affecting turnover and turnaway intention of newspaper journalists in South Korea through the lens of the push–pull–mooring framework. Survey results of 899 journalists showed that traffic boosting practices push journalists away from organizations. Particularly, senior journalists were more frustrated with the prevalence of traffic boosting practices, while juniors were more sensitive to growth potential and job security. Furthermore, ideological conflict between journalists and their organizations regarding political orientation was positively related to turnover intention. Meanwhile, regardless of the career length, journalists who enjoyed their coworkers were less likely to leave their jobs.

Collaboration enhances career progression in academic science, especially for female researchers

Collaboration and diversity are increasingly promoted in science. Yet how collaborations influence academic career progression, and whether this differs by gender, remains largely unknown. Here, we use co-authorship ego networks to quantify collaboration behaviour and career progression of a cohort of contributors to biennial International Society of Behavioral Ecology meetings (1992, 1994, 1996). Among this cohort, women were slower and less likely to become a principal investigator (PI; approximated by having at least three last-author publications) and published fewer papers over fewer years (i.e. had shorter academic careers) than men. After adjusting for publication number, women also had fewer collaborators (lower adjusted network size) and published fewer times with each co-author (lower adjusted tie strength), albeit more often with the same group of collaborators (higher adjusted clustering coefficient). Authors with stronger networks were more likely to become a PI, and those with less clustered networks did so more quickly. Women, however, showed a stronger positive relationship with adjusted network size (increased career length) and adjusted tie strength (increased likelihood to become a PI). Finally, early-career network characteristics correlated with career length. Our results suggest that large and varied collaboration networks are positively correlated with career progression, especially for women.

Performance and Return to Sport After Open Fracture in National Football League Players

Background: Open fractures are debilitating injuries for athletes. No prior studies have investigated open fractures in National Football League (NFL) players. Purpose: To compare outcomes after open fracture in NFL players in terms of (1) time to return to sport (RTS), (2) postinjury career length and games played per season, (3) postinjury performance, and (4) postinjury performance compared with matched controls. Study Design: Retrospective comparative series; Level of evidence, 3. Methods: Publicly available records were used to identify NFL players who had sustained an open fracture between 1970 and 2018. Controls were matched to injured players by age, experience, position, and preinjury performance. RTS was defined as playing in at least 1 NFL game after open fracture. Comparisons between injured and control players were made using the paired-samples Student t test. Results: Injuries in 37 players were analyzed (age, 27.2 ± 3.6 years; experience, 4.4 ± 3.6 seasons). The 3 most common locations for open fracture were the tibia/fibula (n = 16), hand/finger (n = 12), and forearm/wrist (n = 3). A total of 30 (81%) players had a mean time of RTS of 9.3 ± 8.2 months after open fracture; of these players, 4 (13.3%) who sustained hand/finger open fracture did not undergo surgical treatment. There was no difference in postinjury career length or games played per season between control and injured players. Postinjury performance was similar to preinjury performance in injured players, and postinjury performance scores were similar between injured and control players. There were significant differences between players who sustained upper extremity and lower extremity open fractures in RTS time (4.0 ± 4.8 vs 14.6 ± 7.4 months, respectively; P = .00007) and postinjury performance (6.4 ± 4.3 vs 3.3 ± 2.1, respectively; P = .03). Conclusion: RTS after open fracture among NFL players was high. Players who sustained an open fracture had similar games played per season, career length, and performance compared with matched controls. Players who sustained an upper extremity open fracture had a faster RTS time, higher RTS rate, and improved postinjury performance compared with players who sustained a lower extremity open fracture.

Using context-dependent DEA to analyze the efficiency of highly funded scientists in China

Funding inputs and research outputs have always been two central issues in the science of science. In recent decades, research funding plays an increasingly important role in scientific research. Thus, it is progressively significant for management authorities to measure the research efficiency of highly funded scientists, which can be helpful for them to make effective policies. However, few researchers use quantitative analysis to study these issues. To promote the research in this field, we begin with collecting a dataset. This dataset contains research funding and other information from 345 highly funded scientists in Mainland China. Next, we use the dataset to measure the efficiency of highly funded scientists based on the data envelopment analysis. In this way, highly funded scientists are placed into several levels according to their research inputs and outputs. We also give their attractiveness and progress scores compared to other grades. The learning path for less efficient scientists is also provided. We find that highly funded scientists have relatively high efficiency in three kinds of projects, such as the Major Research Plan. Besides, the career length and career start year are demonstrated to have a limited impact on the highly funded scientists. These patterns are beneficial for the development of the scientific community and management authorities to make policies.
