argued that professions created a stable society by providing structure separate from the state and the military that was less inclined to create authoritarianism or anomie and could create altruism and encourage social responsibility and altruism. This functionalist perspective was extended by Parsons who considered how the function of a profession could change in responses to changes in society. Esther Lucile Brown, an anthropologist, studied various professions starting the 1930s while working with Ralph Hurlin at the Russell Sage Foundation. She published Social Work as a Profession in 1935, and following this publications studying the work of engineers, nurses, medical physicians and lawyers. In 1944, the Department of Studies in the Professions was created at the Russell Sage Foundation with Brown as its head. Theories based on conflict theories following Marx and Weber consider how professions can act in the interest of their own group to secure social and financial benefits were espoused by Johnson (Professions and Powers, 1972) and Larson (The Rise of Professionalism, 1977). One way that a profession can derive financial benefits is limiting the supply of services. Theories based on discourse, following Mead and applying ideas of Sartre and Heidegger look at how the individual's understanding of reality influence the role of professions. These viewpoints were espoused by Berger and Luckmann (The Social Construction of Reality, 1966). System of professions Andrew Abbott constructed a sociological model of professions in his book The System of Professions. Abbott views professions as having jurisdiction over the right to carry out tasks with different possession vying for control of jurisdiction over tasks. A profession often possesses an expert knowledge system which is distinct from the profession itself. This abstract system is often not of direct practical use but is rather optimized for logical consistency and rationality, and to some degree acts to increase the status of the entire profession. One profession may seek control of another profession's jurisdiction by challenging it at this academic level. Abbott argues that in the 1920s the psychiatric profession tried to challenge the legal profession for control over society's response to criminal behavior. Abbott argues the formalization of a profession often serves to make a jurisdiction easier or harder to protect from other jurisdictions: general principles making it harder for other professions to gain jurisdiction over one area, clear boundaries preventing encroachment, fuzzy boundaries making it easier for one profession to take jurisdiction over other
