This final rule modernizes the Medicaid managed care regulations to reflect changes in the usage of managed care delivery systems. The final rule aligns, where feasible, many of the rules governing Medicaid managed care with those of other major sources of coverage, including coverage through Qualified Health Plans and Medicare Advantage plans; implements statutory provisions; strengthens actua...

This paper proposes a novel method for watermarking C source code by exploiting the programming language features.The key idea of our watermarking scheme is a semantics-preserving program transformation, based on a hidden permutation of local identifiers, followed by another hidden permutation of the functions defined in the source code. This last permutation allows to encrypt the prove of owne...

This paper presents Composer, an authoring tool to help creating interactive TV programs for the Brazilian Terrestrial Digital TV System. In Composer, several abstractions are defined creating different document views (structural, temporal, layout and textual). One of these views, the temporal view, preserves as much as possible the timeline paradigm, so popular in TV program editing. Using thi...

This paper describes Purify, a software testing and quality assurance tool that detects memory leaks and access errors. Purify inserts additional checking instructions directly into the object code produced by existing compilers. These instructions check every memory read and write performed by the program-undertest and detect several types of access errors, such as reading uninitialized memory...

This paper addresses the question of whether incumbents can buy political support through targeted public spending. Using a regression discontinuity approach which takes advantage of the quasi-experimental design of a recent Romanian government program that distributed coupons worth 200 Euros to poor families towards the purchase of a computer, we find that program beneficiaries were significan...

In 1990, in an attempt to deal with the devastating impact the collapse of the Soviet bloc inflicted on the Cuban economy, Cuban authorities announced the start of “the special period in time of peace,” an economic adjustment program. The following year the Fourth Communist Party Congress ratified the program and spelled out its main components: (a) a food (Plan Alimentario) and energy import s...

Party membership seems to lose relevance for political careers in many established democracies. Increasing numbers of parties are recruiting non-members as candidates. Yet, what the implications a lack long-term party cohesion? In this paper, I argue that pre-parliamentary is fact crucial cohesion. Using data from Comparative Candidate Survey and voting behavior ca. 2,000 MPs German Bundestag o...
