Using a sample of about 90,000 observations from 38 countries over the 2001-2012 period, we find evidence that following say on pay (SoP) laws, CEO pay growth rates decline and the sensitivity of CEO pay to firm performance improves. Further, the portion of total top management pay captured by CEOs is lower in the post-SoP period, which is associated with(More)
Schistosomiasis mansoni is the third most prevalent endemic parasitic disease in the world. It is estimated that over 200 million people are infected with parasites belonging to one of the Schistosoma species. Of those, 270,000 people (4.6%) suffer from pulmonary arterial hypertension, which is associated with the hepatosplenic form of the disease. This(More)
This paper presents the design and implementation of declarative policy-based adaptive MANET routing protocols. Our work builds upon declarative networking, a recent innovation for building extensible network architectures using declarative languages. We make the following contributions. First, we demonstrate that traditional MANET protocols can be(More)
We explore the joint effect of expected government support to banks and changes in sovereign credit ratings on bank stock returns using data for banks in 37 countries between 1995 and 2011. We find that sovereign credit rating downgrades have a large negative effect on bank stock returns for those banks that are expected to receive stronger support from(More)
This paper presents the design and implementation of PUMA, a declarative constraint-solving platform for policy-based routing and channel selection in multiradio wireless mesh networks. In PUMA, users formulate channel selection policies as optimization goals and constraints that are concisely declared using the Colog declarative language. To efficiently(More)

Employing plasma samples rather than serum samples for serological paratuberculosis diagnosis is practical, especially when bovine TB is assessed in the same cattle herd with the gamma interferon bovine avian (IFN-γ BA) test. We demonstrate that antibody titers in serum and plasma samples, utilizing the PARACHECK(®) ELISA kit, are highly comparable (Cohen's(More)
We present the <i>RapidMesh</i> toolkit for rapid protocol simulation, implementation and experimentation of wireless mesh networks. <i>RapidMesh</i> utilizes <i>declarative networking,</i> a declarative, database-inspired extensible infrastructure that uses query languages to specify behavior. <i>RapidMesh</i> integrates a declarative networking engine(More)
This paper presents a new direction in security awareness tools for system administration-the Host-Network (HoNe) Visualizer. Our requirements for the HoNe Visualizer come from needs system administrators expressed in interviews, from reviewing the literature, and from conducting usability studies with prototypes. We present a tool taxonomy that serves as a(More)
This paper presents DAWN, a declarative platform that creates highly adaptive policy-based mobile ad hoc network (MANET) protocols. DAWN leverages declarative networking techniques to achieve extensible routing and forwarding using declarative languages. We make the following contributions. First, we demonstrate that traditional MANET protocols can be(More)
