Question: Who has more scope of profession, E. L. Doctorow or Julia Peterkin?

Context paragraphs:
Julia Peterkin: Julia Peterkin (October 31, 1880 – August 10, 1961) was an American author from South Carolina.  In 1929 she won the Pulitzer Prize for Novel/Literature, for her novel "Scarlet Sister Mary."  She wrote several novels about the plantation South, especially the Gullah people of the Low Country.  She was one of the few white authors who wrote about the African-American experience.

National Association for Chiropractic Medicine: The National Association for Chiropractic Medicine (NACM) was a minority chiropractic association founded in 1984 that described itself as a "consumer advocacy association of chiropractors".  It openly rejected some of the more controversial aspects of chiropractic, including a basic concept of chiropractic, vertebral subluxations as the cause of all diseases.  It also sought to "reform the chiropractic profession away from a philosophical scope of practice and towards an applied science scope of practice."  It stated that it was "dedicated to bringing the scientific based practice of chiropractic into mainstream medicine" and that its members "confine their scope of practice to scientific parameters and seek to make legitimate the utilization of professional manipulative procedures in mainstream health care delivery."  "While the NACM is focused on furthering the profession, its primary focus is on the rights and safety of the consumers."  The NACM was the object of much controversy and criticism from the rest of the profession.  It quietly dropped out of sight and its demise apparently occurred sometime between May 30, 2008 and March 6, 2010.

John Rathbone Oliver: John Rathbone Oliver (January 4, 1872 – January 21, 1943) was an American psychiatrist, medical historian, author, and priest.  His novel "Victim and Victor" was a contender for the 1929 Pulitzer Prize for Fiction, but was beat out by Julia Peterkin's "Scarlet Sister Mary".

Loon Lake (novel): Loon Lake is a 1980 novel by E. L. Doctorow published in 1980.  The plot of the novel is mostly set on Loon Lake in the Adirondacks during the Depression.  The novel is one of the more experimental works of Doctorow, incorporating a great variety of different techniques, many of which are used for preventing the reader from an easy understanding of the narration: traditional narratives, stream of consciousness, poetry, mixed up chronology.

The Book of Daniel (novel): The Book of Daniel (1971) is a semi-historical novel by E. L. Doctorow, loosely based on the lives, trial and execution of Julius and Ethel Rosenberg.  Doctorow tells the story of Paul and Rochelle Isaacson (corollaries to the Rosenbergs) through the persons of their older son, Daniel, and his sister, Susan, who are college students deeply involved in 1960s politics.

Nursing: Nursing is a profession within the health care sector focused on the care of individuals, families, and communities so they may attain, maintain, or recover optimal health and quality of life.  Nurses may be differentiated from other health care providers by their approach to patient care, training, and scope of practice.  Nurses practice in many specialties with differing levels of prescription authority.  Many nurses provide care within the ordering scope of physicians, and this traditional role has shaped the public image of nurses as care providers.  However, nurses are permitted by most jurisdictions to practice independently in a variety of settings depending on training level.  In the postwar period, nurse education has undergone a process of diversification towards advanced and specialized credentials, and many of the traditional regulations and provider roles are changing.

Optometry: Optometry is a health care profession which involves examining the eyes and applicable visual systems for defects or abnormalities as well as the medical diagnosis and management of eye disease.  Traditionally, the field of optometry began with the primary focus of correcting refractive error through the use of spectacles.  Modern day optometry, however, has evolved through time so that the education curriculum additionally includes intensive medical training in the diagnosis and management of ocular disease in countries where the profession is established and regulated.  Optometrists (also known as Doctors of Optometry in the US and Canada for those holding the O.D. degree or Ophthalmic Opticians in the UK) are medical professionals who provide primary eyecare through comprehensive eye examinations to detect and treat various visual abnormalities and eye diseases.  Being a regulated profession, an optometrist's scope of practice may differ depending on the location.  Thus, disorders or diseases detected outside the treatment scope of optometry are referred out to relevant medical professionals for proper care, more commonly to ophthalmologists who are physicians that specialize in tertiary medical and surgical care of the eye.  Optometrists typically work closely together with other eye care professionals such as ophthalmologists and opticians to deliver quality and efficient eyecare to the general public.

Scarlet Sister Mary: Scarlet Sister Mary is a 1928 novel by Julia Peterkin.  It won the Pulitzer Prize for the Novel in 1929.  The book was called obscene and banned at the public library in Gaffney, South Carolina.  "The Gaffney Ledger" newspaper, however, serially published the complete book.  Dr. Richard S. Burton, the chairperson of Pulitzer's fiction-literature jury, recommended that the first prize go to the novel "Victim and Victor" by John Rathbone Oliver.  His nomination was superseded by the School of Journalism's choice of Peterkin's book.  Evidently in protest, Burton resigned from the jury.

Wakefield (film): Wakefield is a 2016 American drama film directed and written by Robin Swicord, based on the short story of same name by E. L. Doctorow.  (Doctorow's story, in turn, was based very loosely on an 1835 story of the same name by Nathaniel Hawthorne.)  The film stars Bryan Cranston and Jennifer Garner.  Principal photography began on November 30, 2015, in Pasadena, California.

E. L. Doctorow: Edgar Lawrence "E. L." Doctorow (January 6, 1931 – July 21, 2015) was an American novelist, editor, and professor, best known internationally for his works of historical fiction.  He has been described as one of the most important American novelists of the 20th century.
