Designs on the Web: A case study of online learning for design students

The De Montfort University Electronic Campus initiative started in September 1999. Web‐based learning resources and support have been provided for over 3,000 students via a portfolio of thirty projects ranging across all levels of the university and within every faculty. This paper focuses on one aspect of this initiative: the development of online teaching and learning materials to support first‐year IT modules for students of art and design. An undergraduate module has been converted from traditional, face‐to‐face, delivery to a hybrid combination of Web‐based and studio‐based work in accordance with Laurillard's conversational framework. In the first year of use all the new material has been made available on a pilot basis to a group of 440 students in parallel with conventional lectures and seminars. All the students have had access to the online resources; some students have used them, but some have not. Data on student expectations collected prior to starting on the module are compared with student feedback gathered at the end of the module and student performance data across the two mode's of presentation are compared to establish the relative effectiveness of each approach. In addition the paper reviews the resource implications of developing, delivering and supporting online learning and discusses some of the barriers to implementation that were encountered and overcome

Simulation of an automatically-controlled STOL aircraft in a microwave landing system multipath environment

The simulated response is described of a STOL aircraft to Microwave Landing System (MLS) multipath errors during final approach and touchdown. The MLS azimuth, elevation, and DME multipath errors were computed for a relatively severe multipath environment at Crissy Field California, utilizing an MLS multipath simulation at MIT Lincoln Laboratory. A NASA/Ames six-degree-of-freedom simulation of an automatically-controlled deHavilland C-8A STOL aircraft was used to determine the response to these errors. The results show that the aircraft response to all of the Crissy Field MLS multipath errors was small. The small MLS azimuth and elevation multipath errors did not result in any discernible aircraft motion, and the aircraft response to the relatively large (200-ft (61-m) peak) DME multipath was noticeable but small

Discovering the Higgs Bosons of Minimal Supersymmetry with Muons and a Bottom Quark

We investigate the prospects for the discovery at the CERN Large Hadron Collider of a neutral Higgs boson produced with one bottom quark followed by Higgs decay into a muon pair. We work within the framework of the minimal supersymmetric model. The dominant physics background from the production of $b \mu^+\mu^-$, $j\mu^+\mu^-$, j=g,u,d,s,c, and $b {\bar b} W^+W^-$ is calculated with realistic acceptance cuts. Promising results are found for the CP-odd pseudoscalar ($A^0$) and the heavier CP-even scalar ($H^0$) Higgs bosons with masses up to 600 GeV. This discovery channel with one energetic bottom quark greatly improves the discovery potential of the LHC beyond the inclusive channel $pp\to \phi^0\to \mu^+\mu^- +X$.Comment: Version to appear in Phys.

Joint evolution of multiple social traits: a kin selection analysis

General models of the evolution of cooperation, altruism and other social behaviours have focused almost entirely on single traits, whereas it is clear that social traits commonly interact. We develop a general kin-selection framework for the evolution of social behaviours in multiple dimensions. We show that whenever there are interactions among social traits new behaviours can emerge that are not predicted by one-dimensional analyses. For example, a prohibitively costly cooperative trait can ultimately be favoured owing to initial evolution in other (cheaper) social traits that in turn change the cost-benefit ratio of the original trait. To understand these behaviours, we use a two-dimensional stability criterion that can be viewed as an extension of Hamilton's rule. Our principal example is the social dilemma posed by, first, the construction and, second, the exploitation of a shared public good. We find that, contrary to the separate one-dimensional analyses, evolutionary feedback between the two traits can cause an increase in the equilibrium level of selfish exploitation with increasing relatedness, while both social (production plus exploitation) and asocial (neither) strategies can be locally stable. Our results demonstrate the importance of emergent stability properties of multidimensional social dilemmas, as one-dimensional stability in all component dimensions can conceal multidimensional instability
