    Type-two constructions abound in cryptography: adversaries for encryption and authentication schemes, if active, are modeled as algorithms having access to oracles, i.e. as second-order algorithms. But how about making cryptographic schemes themselves higher-order? This paper gives an answer to this question, by first describing why higher-order cryptography is interesting as an object of study, then showing how the concept of probabilistic polynomial time algorithm can be generalized so as to encompass algorithms of order strictly higher than two, and finally proving some positive and negative results about the existence of higher-order cryptographic primitives, namely authentication schemes and pseudorandom functions

    This volume consists of papers presented at First Coonference in Economics co-organized by Izmir Univeristy of Economics and the State University of New York at Cortland on May 24-25, 2006 in Izmir, Turkey. The theme of the conference is "Human and Economic Resources".Human and Economic Resources are high on the economic agenda of most leading economies. No doubt, this is due to the strong relationship between Human and Economic Resources and growth and welfare. Papers presented cover issues such as quality of basic education, improvement of labor market information and analysis, enhancing skills in key sectors including small and medium sized enterprises (SMEs), mobility of skilled persons, enhancing quality, productivity, efficiency of the labor force and the workplace, strengthening cooperation to support trade and investment liberalization.Globalization, international trade, developing countries
