bet365 live casino games In recent years，The problem of low proportion of women in scientific research groups has received widespread attention from society。From the historical perspective，Most members of the National Academy of Sciences and the Academy of Arts and Sciences of the United States are men。In order to study whether female scientific researchers have obtained the same recognition as male colleagues，David Card, an economist at the University of California Berkeley, has measured the trend of gender gap between the National Academy of Sciences and the Academy of Arts and Sciences of the National Academy of Sciences and the Sciences of the American Academy of Arts and Sciences in the past 60 years。

Cade and others first chose psychology、Economics and Mathematics, the three gender differences with large gender differences，The list of active scholars was established according to the topic publications of related top journals。Subsequent，Researchers have developed a series of models，Compared with the probability change of female scientific researchers selected as members of the two sciences in the past 60 years。Researchers discovered，Compared with men with similar academic works and citation records，The possibility of a woman becoming a member of the Academy of Sciences 60 years ago。The 1990s，The bet365 live casino games election process of members of the two sciences has more or less gender neutrality。But，In the past 20 years，Psychology、Economics and mathematics are actively prefer women。The possibility of a woman becoming a member of the Academy of Sciences is 3-15 times that of men with similar publishing and reference records。Cade said，Even so，The representativeness of female scientific researchers in the field of mathematics and economics has not yet reached 50%。

Current，The procedure of the election members of the two sciences is still opaque，Researchers cannot systematically analyze the mechanism of female scientific researchers in the United States。Professor Nagore Iriberri at the Department of Economics Analysis, Basque University of Spain，Considering the discrimination that women suffer in the history bet365 Play online games of scientific development、Published an article in the top journal facing many obstacles，Social recognition with low scientific research work and other academic career development difficulties，The American academic community decides to give priority to women who become members of the Academy of Sciences，to increase the proportion and existence of female scientific researchers。

Cade pointed out，Priority to consider women does not mean that female scientific researchers join the agency with lower academic standards，Instead, a paradigm change has occurred in the filtering itself: the academic world has certain willingness to increase the representativeness of women in the academic world。National Academy of Sciences、The report published by bet365 best casino games the National Academy of Engineering and the National Medical College in 2007 in "Beyond prejudice and obstacles"，Requires the Honorary Association to review its nomination and election procedures，To solve the problem of insignificant representatives of women in their members。
