We construct a generic, simple, and efficient scheduling policy for stochastic processing networks, and provide a general framework to establish its stability. Our policy is randomized and prioritized: with high probability it prioritizes jobs which have been least routed through the network. We show that the network is globally stable under this policy if there exists an appropriate quadratic ...

Our world is a complex socio-technical system-of-systems (Chappin &Dijkema, 2007; Nikolic, 2009). Embedded within the geological, chemical and biological planetary context, the physical infrastructures, such as power grids or transport networks span the globe with energy and material flows. Social networks in the form of global commerce and the Internet blanket the planet in information flows. ...

Drawing on an in-depth analysis of eight global health networks, a recent essay in this journal argued that global health networks face four challenges to their effectiveness: problem definition, positioning, coalition-building, and governance. While sharing the argument of the essay concerned, in this commentary, we argue that these analytical concepts can be used to explicate a concept that h...

this article contends that legitimacy in the exercise of power comes from the consent of those subject to it. in global health, this implies that the participation of poor country citizens is required for the legitimacy of major actors and institutions. but a review of institutions and processes suggests that this participation is limited or absent. particularly because of the complex political...

In large networks, maintaining precise global network state information is almost impossible. Many factors, including non-negligible propagation delay, infrequent link state update due to overhead concerns, link state update policy, resource reservation, and hierarchical topology aggregation, have impacts on the precision of the global network state information. To achieve efficient Quality of ...

The global health agenda has been dominating the current global health policy debate. Furthermore, it has compelled countries to embrace strategies for tackling health inequalities in a wide range of public health areas. The article by Robert and colleagues highlights that although globalization has increased opportunities to share and spread ideas, there is still great asymmetry of power accor...

The formulation of global health policy is political; and all institutions operating in the global health landscape are political. This is because policies and institutions inevitably represent certain values, reflect particular ideologies, and preferentially serve some interests over others. This may be expressed explicitly and consciously; or implicitly and unconsciously. But it’s important t...

Regulatory competition between the US and EU influences the development of the standards that define global ICT networks. Traditional standard-setting organizations that once developed those standards have been marginalized by the rapid pace of innovation in ICT, and informal standard-setting organizations have rushed into the breach. US policy favors informal standard-setting processes and oft...

According to structure feature of satellite network management, the global policy servers and the local policy servers have been established. Function modules of satellite networks were designed on the base of system architecture, such as policy management tools, policy library, policy decision point and policy execution point, etc. The policy description method based on XML has been implemente...

Gorik Ooms recently made a strong case for considering the centrality of normative premises to analyzing and understanding the underappreciated importance of the nexus of politics, power and process in global health. This critical commentary raises serious questions for the practice and study of global health and global health governance. First and foremost, this commentary underlines the impor...
