Negative relation between unemployment and inflation is known as the Philips model, which states, when inflation is high, unemployment gently decries and when unemployment is low, salaries will increase rapidly. While economic planners of the country tend to impart this situation highly, it would fall down, because frequent increase of inflation with the hope of keeping unemployment low permanently, ultimately will cause rise in expected inflation of organizations and lead to change in their recruitment decisions. In a section of this model, it has also analyzed, relation between income, investment, and consumption. Regular Philips model with derivative deals with first and second level of calculations, however this model has faced many weaknesses and deficiencies in economic cycle of Iran. Regarding its implementation in the economy of Iran, in this research, through substitution of Caputo fractional-order derivatives, we reach out “Philips model of Fractional-order”. Moreover, by numerical calculation of resulted equations and using Maple software, we over reach to Philips curve of Fractional-order in multiple various orders. According to achieved results, this model highly depends on derivation orders and different outcomes will be acquired through various derivation orders. Acquired model in the economy of Iran (situational format in Sugar and Sugar cube Industries) has been studied through phasic technic which proves meaningfulness of relations between variables of the model.

After briefly recounting a strange, quasi-mystical experience I had while first reading Immanuel Kant’s Critique of Pure Reason , I devote most of this article to exploring various similarities between theories Kant developed and ideas more commonly associated with Paul Tillich. Hints are drawn from Chris Firestone’s book, Kant and Theology at the Boundaries of Reason , which argues that my interpretation of Kant echoes themes in Tillich’s ontology. Among the themes whose Kantian roots I explore are Tillich’s theories of: God as the Ground of Being; faith as ultimate concern; courage as the proper life-choice in the face of the anxiety that naturally arises out of an honest response to the human situation, given our fundamental alienation from the divine; the crucial role of cultural symbols in bringing faith into historically realistic expressions; political forms as ideally self-negating; and love as a gift that we must express with power and justice in order to be efficacious. After considering whether Kant influenced Tillich more than Tillich ever admitted, I conclude by wondering if my own effort to develop an “affirmative” interpretation of Kant’s theory of religion may have itself had a hidden influence from my prior reading of Tillich.
