Now，Young researchers face increasing pressure to secure tenure and Bet365 lotto review funding，Although relevant departments are working hard to solve the problem，But no solution found。A new study finds a key factor causing this condition，That is, as the size of the Bet365 lotto review team continues to expand，The innovativeness of young researchers at the bottom of the team is declining。Future，This will hinder the career development of young researchers。

Researchers said，The current Bet365 lotto review team is getting larger and larger，Average 1 per paper since 1970.8 authors increased to 3 in 2004.6 digits，The growth rate has reached 1 times。A study published in the journal Nature Biotechnology shows，The average team size in a certain Bet365 lotto review field increases by 1 person，Young PhDs in this discipline are 24% less likely to be tenured，29% less likely to get tenure，11% more likely to leave academia，The largest number of female young researchers and foreign-born young researchers are among those leaving。

　University of Kansas Science、Professor Donna Ginther, Director of the Center for Technology and Economic Policy, is the leader of the study，She said，Many scholars have studied the benefits of teamwork in the past，But these studies ignore the costs of teamwork。Actually，Small scientific Bet365 lotto review teams are more innovative，Large scientific Bet365 lotto review teams may have a negative impact on young researchers at the bottom of the team，Such as damaging their innovation and career development prospects。

In the new study, Ginser tested a theoretical model developed by Catherine de Fontenay, associate professor of economics at the University of Melbourne, and Kwanghui Lim, associate professor in the business school，That is, when the scale of the scientific Bet365 lotto review team continues to expand，The early careers of their team members will be affected。Ginser also combined data from the National Science Foundation’s survey of PhD recipients with the average number of authors on journal papers in seven major scientific fields，She found that the expansion of team size between 1973 and 2013 was a key reason for the decline in the chances of new PhDs receiving tenure (the National Science Foundation did not conduct survey data on PhD recipients after 2013)。Although other scholars speculate that there are other reasons also fueling this trend，For example, the end of the mandatory retirement system in American academia in 1994，But Kinser thinks，All this is due to the expansion of the scientific Bet365 lotto review team，The dynamic development of the team will affect the career trajectories of team members。

Kinser thinks，The expansion of Bet365 lotto review size is not only detrimental to young researchers，And it is also detrimental to self-correction of its scientific abilities。Current funding policies can be a powerful lever to address these issues。Although some believe that expanding scientific funding will alleviate the problem of attrition of young researchers，But that’s not the case。National Institutes of Health (U.S. When the National Institutes of Health doubled its funding between 1998 and 2003，The influx of funds did not increase the number of laboratories，Instead, we expanded the size of the laboratory Bet365 lotto review，The proportion of PhDs receiving tenure in the life sciences dropped the most during this period。

Kinser thinks，Compared with increasing the amount of funding，It may be more appropriate to provide financial support to researchers who plan to establish laboratories。This can provide young researchers with start-up capital for better scientific Bet365 lotto review，This is also more beneficial to their future career development。

The academic community needs to conduct more in-depth Bet365 lotto review in the future，Investigating why young scholars, especially those from specific groups, leave academia。Current Bet365 lotto review mainly focuses on team size in a certain field，Did not explore the mechanism behind the dynamic transformation of its team members。There is still a lot of work to be done in the future，such as tracking the career trajectories of individual scientists，And study the reasons。
