This paper is concerned with heterogeneity and the notion of boundaries within systems design. It uses case study material to identify sources of heterogeneity and to understand how these are oriented to within the practicalities of design work. A key concept for analysing work practices is the notion of place. The paper analyses the qualities of the places in which design work takes place (reg...

Hahn and Wallsten (Econ. Voice 3(6):1–7, 2006) wrote that network neutrality “usually means that broadband service providers charge consumers only once for Internet access, do not favor one content provider over another, and do not charge content providers for sending information over broadband lines to end users.” In this paper we study the implications of non-neutral behaviors under a simple ...

Two clichés sum up the telecommunications policy world for the past half dozen years. First, the only constant is change. Second, the more things change, the more they stay the same. The main topics of debate have turned, in just three years, from unbundled network elements and “open access” to video franchising reform and “net neutrality.” But the deep structure of the debate remains eerily fa...

We propose two generalizations of the Banzhaf value for partition function form games. In both cases our approach is based on probability distributions over the set of coalition structures that may arise for any given set of players. First, we introduce a family of values, one for each collection of these latter probability distributions, defined as the Banzhaf value of a coalitional game obtai...

Much of the policy debate and scholarly literature on network neutrality has addressed whether the Federal Communications Commission (“FCC”) has statutory authority to require Internet Service Providers (“ISPs”) to operate in a nondiscriminatory manner. Such analysis largely focuses on questions about jurisdiction, the scope of lawful regulation, and the balance of power between stakeholders—ge...

The r−n interaction energy, 1 ≤ n < 3, for a infinitely periodic system with explicit charges and a neutralizing, uniform background charge density is derived. An Ewald based expression for this energy has an extra term proportional to the square of the total explicit charges of the system. This expression may be useful for simulations in which explicit charge neutrality does not hold or for wh...
