Use interactive multimedia to improve your programming course
This paper reports first year students’ experiences with multimedia-based learning for programming and its influence on students obtained from two case studies at Napier and Brunel universities. Engineering students at the universities have taken programming courses from their first year and many have showed difficulties in their learning. The main reason is that it is a very abstract domain, which means that both lecturers and students can have difficulties in explaining and understanding abstract concepts verbally. Considering the strengths of Interactive Multimedia(IMM), i.e. interactivity and visualisation, we decided to use it to improve students’ learning.
An empirical study was planned and IMM materials were designed for this. A trial and two case studies were carried out from December 2000 to June 2001. The designed materials were integrated into the curriculum as a teaching aid and self-guided learning materials. The data gathered from the case studies indicated that many students felt the multimedia-based learning helped their understanding of the programming concepts, and some became very motivated in programming. Also, using the interactive multimedia materials for both teaching and learning enhanced students’ learning experience. At last, we found educating both lecturers and students on what is multimedia-based learning prior to a course can increase its effectiveness
Network architecture, salience and coordination
This paper reports the results of an experimental investigation of
monotone games with imperfect information. Players are located at
the nodes of a network and observe the actions of other players only if
they are connected by the network. These games have many sequential
equilibria; nonetheless, the behavior of subjects in the laboratory is
predictable. The network architecture makes some strategies salient
and this in turn makes the subjects’ behavior predictable and facilitates
coordination on efficient outcomes. In some cases, modal behavior
corresponds to equilibrium strategies
Factorization in graviton interactions
The study of factorization in the linearized gravity is extended to the
graviton scattering processes with a massive scalar particle, with a massless
vector boson and also with a graviton. Every transition amplitude is shown to
be completely factorized and the physical implications of their common factors
are discussed.Comment: 5 pages, Revtex 3.0, SNUTP 93-7
CP violation at one loop in the polarization-independent chargino production in e+e- collisions
Recently Osland and Vereshagin noticed, based on sample calculations of some
box diagrams, that in unpolarised e+e- collisions CP-odd effects in the
non-diagonal chargino-pair production process are generated at one-loop. Here
we perform a full one-loop analysis of these effects and point out that in some
cases the neglected vertex and self-energy contributions may play a dominant
role. We also show that CP asymmetries in chargino production are sensitive not
only to the phase of mu parameter in the chargino sector but also to the phase
of stop trilinear coupling A_t.Comment: 14 pages, 5 figure
Probing MSSM Higgs Sector with Explicit CP Violation at a Photon Linear Collider
The CP properties of Higgs bosons can be probed through their s-channel
resonance productions via photon-photon collisions by use of circularly and/or
linearly polarized backscattered laser photons at a TeV-scale linear e^+ e^-
collider. Exploiting this powerful tool, we investigate in detail the Higgs
sector of the minimal supersymmetric Standard Model with explicit CP violation.Comment: 18 pages, 5 figures. Some comments added and typos corrected. To

Controlling quasiparticle excitations in a trapped Bose-Einstein condensate
We describe an approach to quantum control of the quasiparticle excitations
in a trapped Bose-Einstein condensate based on adiabatic and diabatic changes
in the trap anisotropy. We describe our approach in the context of Landau-Zener
transition at the avoided crossings in the quasiparticle excitation spectrum.
We show that there can be population oscillation between different modes at the
specific aspect ratios of the trapping potential at which the mode energies are
almost degenerate. These effects may have implications in the expansion of an
excited condensate as well as the dynamics of a moving condensate in an atomic
wave guide with a varying width
