economic development plans normally contain some policy objectives, especially for the most important macroeconomic variables. governments are expected to take best policies to achieve these objectives, although due to some structural or other impediments they may fail to touch the objectives. we have attempted to uncover the determinants of private consumption and investment as the objectives ...

With the increase in information accessibility, security and privacy of data is a key concern, underscoring the need for managing security of system resources and objects in an enterprise. One of the most popular access control management approaches is to abstract security administration tasks by employing system and security policies [1]. While policy based security management approach offers ...

BACKGROUND Since the passage of Proposition 99, California's comprehensive tobacco control programme has benefited from a localised policy adoption process that allows for the innovation and diffusion of strong local tobacco control policies throughout the state. METHODS The policy adoption continuum is described in the context of California's smoke-free workplace movement, and the influence ...

Wang, Qihua. Ph.D., Purdue University, May 2009. Access Control Policy Management. Major Professor: Ninghui Li. Access control is the traditional center of gravity of computer security [1]. People specify access control policies to control accesses to resources in computer systems. The management of access control policies include policy specification and policy analysis. In this dissertation, ...

Every autonomous agent operating in realistic settings must deal with incomplete state information. Sensory limitations, due to hardware constraints and/or limited interpretation algorithms, introduce hidden states which can prevent the acquisition of optimal control policies for a given task. This paper addresses this problem within the dynamical systems framework. The idea is to treat the age...

This paper investigates emission and stock abatement policy decisions by the use of a stochastic optimal control model with a continuous-time setting. Environmental policies are typically referred as emission flow abatement (reduction) activities and thus, can be formulated as classical optimal control problems. However, because of recent shifts in the focus of policy measures, it is getting re...

In this paper meta-policies for access control policies are presented. There has been a lot of research into the various ways of specifying policy for a single domain. Such domains are autonomous and can be managed by the users or by a specific system administrator. It is often helpful to have a more general policy description in order to restrict the ways in which policy can be modified. Meta-...

iran’s significant success in implementing family planning (fp) during the past 25 years, has made it a role model in the world. the total fertility rate (tfr) in iran has dropped from 6.5 in 1960 to 1.6 in 2012, which is well below the targeted value of 2.2 for the country. iran’s success story, however, did not merely root in the implementation of fp programs. in other words, families’ strong...
