Analysis of Radio Spectrum Market Evolution Possibilities

A tremendous growth in wireless traffic volumes and a shortage of feasible radio spectrum has led to a situation where the old and rigid spectrum regime is not a viable option for spectrum management and a shift towards a more market driven approach has begun. Great uncertainty still exists over how such a radio spectrum market will come about and what kind of shape it would take. This paper studies some long term macro level evolution possibilities for how this radio spectrum market could emerge and what would be the corresponding value chain configurations. The scenario planning and system dynamics methods are utilized to build four alternative future spectrum market scenarios.Spectrum Markets, Spectrum Policy, Flexible Spectrum Usage, Cognitive Radio, Value Networks, Scenario Planning, System Dynamics.

Mobile Communications Industry Scenarios and Strategic Implications for Network Equipment Vendors

Mobile infrastructure markets have changed dramatically during the past years. The industry is experiencing a shift from traditional large-scale, hardware-driven system roll-outs to software and services -driven business models. Also, the telecommunications and internet worlds are colliding in both mobile infrastructure and services domains requiring established network equipment vendors and mobile operators to transform and adapt to the new business environment. This paper utilizes Schoemaker's scenario planning process to reveal critical uncertain elements shaping the future of the industry. Four possible scenarios representing different value systems between industry's key stakeholders are created. After this, five strategic options with differing risk and cost factors for established network equipment vendors are discussed in order to aid firm's strategic planning process. --

Philadelphia's Councilmanic Prerogative: How It Works and Why It Matters

This report examines the Philadelphia legislative practice known as "councilmanic prerogative," through which individual City Council members make nearly all of the land use decisions in their jurisdictions. This report on councilmanic prerogative is grounded in extensive analysis of city records and interviews with dozens of government officials, developers, political figures, academics, and community advocates. It is the first independent examination of the practice in the city

Dihadron Fragmentation Functions in the NJL-jet model

The NJL-jet model provides a framework for calculating fragmentation functions without introducing ad hoc parameters. Here the NJL-jet model is extended to investigate dihadron fragmentation functions.Comment: 4 pages, 5 figures, Proceedings of 8th Circum-Pan-Pacific Symposium on High Energy Spin Physic

A Browser-based IDE for the MUzECS Platform

We report on a scalable, portable, and secure visual development environment for programming embedded Arduino platforms with Chromebooks in a successful secondary school computer science curriculum. Our web-based environment is part of the larger MUzECS project, an inexpensive replacement module for the Exploring Computer Science (ECS) course being widely deployed in United States high schools. Students use MUzECS to gain a deeper understanding of computing, through a set of blocks which provide appropriate abstractions for working with low-level hardware. MUzECS improves upon the existing curriculum module by reducing the hardware cost by an order of magnitude, while still preserving the key ECS pillars of computer science content, student inquiry and classroom equity. Programming with visual blocks provides a more attractive tool for introductory courses than traditional approaches, and yet enables high-impact exploration activities such as building a series of embedded musical instruments. The current work combines and modifies several existing tools to eliminate technical barriers on low-cost platforms like Chromebooks, such as the reliance on special block-based toolchains, remote compilation servers, or multi-stage transfers for student code

Reintegrating the Social Sciences: The Dahlem Group

Social science disciplines see themselves as distinct, with their own territory, their own methods, and their own framework. Within such an environment multidisciplinary work involves enormous conflict and translation problems. This situation is no longer acceptable. Dealing with modern problems requires researchers with broad transdisciplinary knowledge and with the ability to communicate with other social science researchers in a way that will allow them to arrive at transdisciplinary recommendations. Complex issues such as healthcare, income distributions, crime prevention, industrial policy, agriculture require not only insights from multiple social disciplines, but the integration of those insights. This document offers a proposal for training social science researchers. Specifically, it proposes reintegrating the social sciences by modifying the current system of training—which provides completely separate training for researchers in each sub-discipline—to incorporate a common first year “core"of training for all social science researchers. If implemented, the proposal will reduce the babble that currently characterizes much of the interdisciplinary conversations.
