Total Cross Sections and Event Properties from Real to Virtual Photons

A model for total cross sections with virtual photons is presented. In particular gamma*-p and gamma*-gamma* cross sections are considered. Our approach extends on a model for photoproduction, where the total cross section is subdivided into three distinct event classes: direct, VMD and anomalous. With increasing photon virtuality, the latter two decrease in importance. Instead Deep Inelastic Scattering dominates, with the direct class being the O(alpha_s) correction thereof. Hence, the model provides a smooth transition between the two regions. By the breakdown into different event classes, one may aim for a complete picture of all event properties.Comment: 1+34 pages, LaTeX2e, 24 eps figures, submitted to J. High Energy Phy

Two frameworks for preparing teachers for the shift from local to global educational environments

The research outlined in this paper is based on the convergence of two conceptual frameworks that guide the transfer of knowledge and skills from traditional teacher education, which focused on teaching in single classrooms, to open networked learning environments that include both inter-institutional teaching and learning and local and global community engagement. Through these frameworks, schools can be extended in terms of time, space, organisation, and capacity. This will be demonstrated on the basis of New Zealand research in inner-city urban environments and Canadian research in rural Newfoundland and Labrador. There are implications for the professional education of teachers from schools that have the capacity to engage with global learning environments including new ways of relating to learners, learners’ parents, networks and communities. Several of these implications will be analysed in the conclusion of the paper and should generate discussion that will inform current and future research

Competitively neutral universal service obligations

Universal service obligations impose specific costs on the universal service provider. The measure of these costs and their financing have been studied along two complementary lines of reasoning: is the universal service obligation sustainable? Who should bear its costs? Most often, a two-step procedure is put forward. In a first step the cost of USO must be assessed; in a second step the USP must be compensated for this cost. In this paper we argue that this procedure is most often problematic because the implementation of the compensation scheme directly affects the effective cost of USO. We therefore put forward an alternative approach to this problem which does not rely on this two-step procedure and fully acknowledges the distortions that result from the compensation mechanism.universal service obligations, cost-sharing mechanism, competitive neutrality

A Comprehensive Workflow for General-Purpose Neural Modeling with Highly Configurable Neuromorphic Hardware Systems

In this paper we present a methodological framework that meets novel requirements emerging from upcoming types of accelerated and highly configurable neuromorphic hardware systems. We describe in detail a device with 45 million programmable and dynamic synapses that is currently under development, and we sketch the conceptual challenges that arise from taking this platform into operation. More specifically, we aim at the establishment of this neuromorphic system as a flexible and neuroscientifically valuable modeling tool that can be used by non-hardware-experts. We consider various functional aspects to be crucial for this purpose, and we introduce a consistent workflow with detailed descriptions of all involved modules that implement the suggested steps: The integration of the hardware interface into the simulator-independent model description language PyNN; a fully automated translation between the PyNN domain and appropriate hardware configurations; an executable specification of the future neuromorphic system that can be seamlessly integrated into this biology-to-hardware mapping process as a test bench for all software layers and possible hardware design modifications; an evaluation scheme that deploys models from a dedicated benchmark library, compares the results generated by virtual or prototype hardware devices with reference software simulations and analyzes the differences. The integration of these components into one hardware-software workflow provides an ecosystem for ongoing preparative studies that support the hardware design process and represents the basis for the maturity of the model-to-hardware mapping software. The functionality and flexibility of the latter is proven with a variety of experimental results

Directing the technology intelligence activity: An ‘information needs’ template for initiating the search

In technology-intensive sectors, strategic planning requires relevant and timely information about new/emerging technologies – this is a critical input. Therefore, technology intelligence activities should be directed to capture and deliver pertinent technological information. However, there is a distinct lack of tools for helping organizations to determine what constitutes useful/appropriate information for their needs. To address this issue, an ‘information needs’ template has been developed to support the process of eliciting and articulating meaningful search queries to guide those who will conduct and provide the necessary intelligence. The use of the template also acts as a means of priming the technology intelligence as it identifies and points to potentially useful sources of knowledge. It covers the spectrum of sources from leveraging internal information, through spanning organizational boundaries to access external sources across the specific industry and neighboring industries, to more distant fields of knowledge. Additionally, the template has sections for distinguishing ‘who to watch’ versus ‘who to talk to’. The deployment of the template can be integrated with roadmapping, using the roadmap landscape to feed hotspots/themes/gaps/white spaces into the template, which are then unpacked to determine the information needs of the organization.Non
