bet365 Play online games Private charity donation has always been an important source of funds for American researchers，Especially when government funding fails to keep up with the growth rate of scientific research costs。Although some large private donations are gradually being well known for the public，But most people know very little about the huge charity ecosystem that supports scientific research supporting American universities and scientific research institutions。Recent，The Journal of the Science Report published the papers of Alex Gates and its teams of data science assistants at the University of Virginia in the United States，Try to clarify the elements of the American scientific research field that is well known but crucial。

Gates realized，In order to comprehensively describe and analyze the situation of charitable funding and support American scientific research，Detailed and reliable data must be obtained。In recent years，In order to facilitate the public to obtain information，More effectively supervise and evaluate the financial health status and operating efficiency of non -profit organizations，The Federal Taxation Agency optimized the tax declaration form that non -profit organizations must submit，so that its financial data can be read and processed directly by the computer program。

Gates and others use machine learning and network science methods，Revealing a variety of related factors supported by charitable groups to support US scientific research。First，They analyzed more than 3.6 million tax records submitted by about 685,000 universities and research institutions bet365 Play online games from 2010 to 2019，Evaluation of the investment scale of charitable funds in US scientific research。Research Discovery，During the investigation，A total of 69,675 non -profit organizations participated in the Give and Receiving of 926124 gifts，The total amount is as high as 208 billion US dollars。In recent years，The annual charitable funds used in scientific research have been close to $ 30 billion，Almost the scientific research support funds provided by the National Institute of Health。

Next，Gates and others clarified the public's common misunderstanding of American scientific research charitable donations。People generally think，Scientific research charitable expenditures are mainly driven by huge donations of millions of dollars。But in fact，Large donation is really rare，Small donations are much more。other，Society usually believes that the scientific community follows eliteism，Think of the best scientific bet365 Play online games concept should get the most funding support。Gates and others found，Geographical location and other factors affect the donation decision of charitable groups，Some European and American charityists have clearly stated that research institutions to donate to local communities。

again，Research results show，The number of charity funds obtained by different research institutions is highly correlated with the degree of fund support they obtained from the National Science Foundation。This high correlation implies a deeper problem，That is, there may be inequality in the distribution of public research funds。If an institution has obtained more support through public funding channels，Its rich resources and high reputation are more likely to attract donations from charitable groups。This will cause the distribution of resources between different research institutions to be even more uneven。For a long Bet365 lotto review time，Institutions with rich resources may continue to get more funds，and institutions with less resources are difficult to get full support，This will affect the improvement and development of its research ability。

Research also found，Private donors and non -profit organization prefer long -term fund -funded institutions。If the donor has funded the same institution for two consecutive years，So the probability of renewal in the third year is 80%。If the donor and the institution have a funding relationship for 7 years，The probability of continuing donations is as high as 90%。For this，Gates and others said，Stable acquisition of charity funds is conducive to the release of innovative potential for scientific research institutions、overcome complex problems。But this phenomenon may also originate from inertia，As a result, institutions that scientific research funds are cut by the government Bet365 app download are facing financial difficulties。At the same time，Gates and others also found，Donors with the same focus tend to support the same institution，This may limit the opportunity to obtain funds from other scientific research institutions，Affected the balanced allocation of scientific research funds。
