A number of databases around the world currently host a wealth of genomic data that is invaluable to researchers conducting a variety of genomic studies. However, patients who volunteer their genomic data run the risk of privacy invasion. In this work, we give a cryptographic solution to this problem: to maintain patient privacy, we propose encrypting all genomic data in the database. To allow ...

This paper provides an alternative behavioral foundation for an investor’s use of power utility in the objective function and its particular risk aversion parameter. The foundation is grounded in an investor’s desire to minimize the objective probability that the growth rate of invested wealth will not exceed an investor-selected target growth rate. Large deviations theory is used to show that ...

It is well known that if costlessly enforceable contracts regulate all of the actions of economic actors that a ect the well being of others, competitive equilibria are Pareto e cient regardless of the distribution of wealth. However where actions such as risk taking and hard work are not subject to such contracts, the assignment of residual claimancy over income streams and control over assets...

purpose: this paper addresses whether and how the sarbanes-oxley act of 2002(sox) affects shareholder wealth (firm value) by focusing on the trade-off between improved corporate governance leading to a lower cost of capital and increased managerial compliance costs of regulations. design/methodology: we use an analytical model of solving the management utility maximization function and the chan...

Kuznar’s (CA 42:432–40) proposed relationship between social status (wealth), risk preference, and utility bears further scrutiny. The author proposes “that there will be a general curvilinear relationship between wealth and risk sensitivity in which the poor and the wealthy will prefer risky prospects whereas those with more moderate wealth will be risk-averse” (p. 437). He attempts to clarify...

Profit maximization (PM) is to select a subset of users as seeds for viral marketing in online social networks, which balances between the cost and profit from influence spread. We extend PM that under general strategy, form continuous (CPM-MS) problem, whose domain on integer lattices. The objective function our CPM-MS dr-submodular, but non-monotone. It typical case unconstrained dr-submodula...
