This newspaper comprehensively reports from foreign media In recent years，The low proportion of women in the scientific research community has received widespread attention from society。Historically，The vast majority of members of the National Academy of bet365 joining bonus code and the American Academy of Arts and bet365 joining bonus code are men。To study whether female researchers receive equal recognition as their male colleagues，University of California, Berkeley, economist David Card and others measured trends in the gender gap among members of the National Academy of bet365 joining bonus code and the American Academy of Arts and bet365 joining bonus code over the past 60 years。

Card and others first chose psychology、Economics and mathematics are three academic fields with large gender differences，Built a list of active scholars based on relevant top journal publications。Afterwards，Researchers developed a series of models，Compare changes in the probability of female researchers being elected as members of two academies of bet365 joining bonus code over the past 60 years。Researchers found，Compared to men with similar academic publication and citation records，Women were less likely to be members of the Academy of bet365 joining bonus code 60 years ago。1990s，The process of selecting members of both academies is more or less gender neutral。However，In the past 20 years，Psychology、Economics and mathematics are all three fields that actively favor women。Women are 3-15 times more likely to be members of the Academy of bet365 joining bonus code than men with similar publication and citation records。Card said，Even so，The representation of female researchers in the fields of mathematics and economics still does not reach 50%。

Currently，The procedures for electing members of the two academies are not yet transparent，Researchers are unable to systematically analyze the mechanism by which female researchers are selected in American academia。Nagore Iriberri, professor of economic analysis at the University of the Basque Country in Spain, speculated，Considering the discrimination suffered by women in the history of scientific development、The barriers to publishing in top journals，As well as difficulties in academic career development such as low social recognition of scientific research work，American academia decides to give priority to women becoming members of the Academy of bet365 joining bonus code，Thus increasing the proportion and presence of female scientific researchers。

Card pointed out，Prioritizing women does not mean that female researchers join the institution with lower academic standards，Rather, there has been a paradigm shift in the selection itself: there is a certain will to increase the representation of women in academia。National Academy of bet365 joining bonus code、In the 2007 report "Beyond Bias and Barriers" published by the National Academy of Engineering and the National Academy of Medicine，Ask honor societies to review their nomination and election procedures，To address the underrepresentation of women among its members。
