Mechanisms for coordination

The lawn-mowing analogy is also interesting in that up to a certain point there will be a linear speedup as mowers are added. This speedup occurs because the mowers do not interfere with each other s work and have efficient mechanisms for coordinating their efforts. The lawn-mowing problem exhibits very good data paraHeHsm. 

COST has developed into one of the largest frameworks for research cooperation in Europe and is a valuable mechanism for coordinating national research activities in Europe. Today it has almost 200 actions and involves nearly 30,000 scientists from 32 European member countries and more than 50 participating institutions from 11 nonniember countries.

ESF 8—Public Health and Medical Services Provides the mechanism for coordinated federal assistance in response to public health and medical care needs for potential or actual Incidents of National Significance or during a developing potential health and medical situation. HHS is the ESF 8 coordinator. 

ESF 13—Public Safety and Security Presents a mechanism for coordinating and providing federal noninvestigative/noncriminal law-enforcement, public-safety, and security capabilities and resources during potential or actual Incidents of National Significance. DHS and the Department of Justice are joint ESF 13 Coordinators.

Continued mitochondrial oxidation of NADH and the reduction of O2 are dependent on sufficient ADP being present. This phenomenon, termed respiratory control, is an Important mechanism for coordinating oxidation and ATP synthesis in mitochondria. 

The research community has responded to the E-Business challenge. Despite the infamous dot-com bust in the early 2000 s, scores of research initiatives, workshops, technical papers, and special journal issues have been devoted to the subject. E-Business remains a critical subject not only in the research community, but also in corporate boardrooms. Instead of the revolution that would replace every facet of business, the rise of E-Business might be viewed as the emergence of new economic intermediaries that offer opportunities for innovation. These new intermediaries offer different means to respond to market demands (e.g., Internet vs. traditional channels), to facilitate sourcing, procurement, and price discovery (e.g., electronic auctions), and to develop new mechanisms for coordination and execution (e.g., dynamic pricing, revenue management, and collaborative forecasting).

One of the main differences between the polymerization kinetics with coordination catalysts and free-radical initiators is that the former depends on the characteristics of the active site as well as on monomer type, while the latter is almost exclusively regulated by monomer type. As we will see, even though this may not constitute a problem for establishing an operative mechanism for coordination polymerization, it creates a significant challenge for model parameter estimation. 

Several metallocene, late transition metal, and homogeneous Ziegler-Natta catalysts behave as single-site catalysts, while all heterogeneous Ziegler-Natta and Phillips catalysts have more than one site type. The mechanism for coordination... 

Several mechanisms for coordination polymerization were proposed and an early one was represented by the Natta s bimetalhc mechanism, which is reported in Fig. 1.8. 

Open source software development operates quite differently than traditional software development. Developers do not meet face to face. There are few schedules. In all but the most prominent projects, there is no plan. Developers choose what they work on and how much time they spend working on it. In almost all cases, developers do not get paid for their work. Traditional mechanisms for coordinating work (e.g., schedules, plans, face to face meetings) are absent [2], yet smdies show that distributed development needs coordination more than collocated development [3]. We are just starting to learn what drives these communities.
