Question:
Jonas Edward Salk (; October 28, 1914 - June 23, 1995) was an American medical researcher and virologist. He discovered and developed one of the first successful polio vaccines. Born in New York City, he attended New York University School of Medicine, later choosing to do medical research instead of becoming a practicing physician. In 1939, after earning his medical degree, Salk began an internship as a physician scientist at Mount Sinai Hospital.
In 1947, Salk became ambitious for his own lab and was granted one at the University of Pittsburgh, but the lab was smaller than he had hoped and he found the rules imposed by the university restrictive. In 1948, Harry Weaver, the director of research at the National Foundation for Infantile Paralysis, contacted Salk. He asked Salk to find out if there were more types of polio than the three then known, offering additional space, equipment and researchers. For the first year he gathered supplies and researchers including Julius Youngner, Byron Bennett, L. James Lewis, and secretary Lorraine Friedman joined Salk's team, as well. As time went on, Salk began securing grants from the Mellon family and was able to build a working virology laboratory. He later joined the National Foundation for Infantile Paralysis's polio project established by President Franklin D. Roosevelt.  Extensive publicity and fear of polio led to much increased funding, $67 million by 1955, but research continued on dangerous live vaccines. Salk decided to use the safer 'killed' virus, instead of weakened forms of strains of polio viruses like the ones used contemporarily by Albert Sabin, who was developing an oral vaccine. After successful tests on laboratory animals, on July 2, 1952, assisted by the staff at the D.T. Watson Home for Crippled Children, Salk injected 43 children with his killed-virus vaccine. A few weeks later, Salk injected children at the Polk State School for the retarded and feeble-minded. In 1954 he tested the vaccine on about one million children, known as the polio pioneers. The vaccine was announced as safe on April 12, 1955.  The project became large, involving 100 million contributors to the March of Dimes, and 7 million volunteers. The foundation allowed itself to go into debt to finance the final research required to develop the Salk vaccine. Salk worked incessantly for two and a half years.  Salk's inactivated polio vaccine was the first vaccine for the disease; it came into use in 1955. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.

Women in Syria constitute 49.4% of Syria's population, and are active participants not only in everyday life, but also in the socio-political fields. Notable examples are president Assad's chief political and media adviser, Bouthaina Shaaban, who also held office as Minister of Expatriates from 2002 and 2008, and Hadiya Khalaf Abbas, the officially elected speaker of the People's Council of Syria and the first woman to have held that position. Whatsoever, the Syrian Civil War put a new obstacle on Syrian women, forcing them to face increasing levels of violence, including war rape, and traditional abusive practices such as honor killings which occur in rural areas and areas held by extremist terrorists.
In the 20th century a movement for women's rights developed in Syria, made up largely of upper-class, educated women. In 1919, Naziq al-Abid founded Noor al-Fayha (Light of Damascus), the city's first women's organization, alongside an affiliated publication of the same name. She was made an honorary general of the Syrian Army after fighting in the Battle of Maysaloun, and in 1922 she founded the Syrian Red Crescent. In 1928 Lebanese-Syrian feminist Nazira Zain al-Din, one of the first people to critically reinterpret the Quran from a feminist perspective, published a book condemning the practice of veiling or hijab, arguing that Islam requires women to be treated equally with men.  In 1963 the Ba'th Party took power in Syria, and pledged full equality between women and men as well as full workforce participation for women.  In 1967 Syrian women formed a quasi-governmental organization called the General Union of Syrian Women (GUSW), a coalition of women's welfare societies, educational associations, and voluntary councils intended to achieve equal opportunity for women in Syria.  Women in Syria have also been integral in acts of nonviolence in response to the Syrian dictator, Bashar Al-Assad. In 2011, conflict was emerging throughout Syria due to the long reign of the Assad family. Throughout the 40 year reign, outbreaks of both nonviolent and violent acts emerged. Assad reacted to these actions by increasing arrests and the killings of Syrian men and women. In response to Assad's increasing arrests and killings, Syrian women and children gathered together. The women and children rallied together and marched to the main highway where they blocked the roadway. This act of nonviolence lead to civilians and military not being able to get where they were going to. This did not make the military very happy. The military came in with tanks and were making various threats towards the protesters but that did not scare them off. Later that day over one hundred Syrian prisoners were released. This was significant because the power women and children had through their nonviolent protest. Their issue of wanting their husbands and sons released from prison was understood by Syrian officials and they knew in order to get the women and children to leave would need to fulfill their demands.

What does that organization do?
a coalition of women's welfare societies, educational associations, and voluntary councils intended to achieve equal opportunity for women in Syria.
