Implicit person theories and change in teacher evaluation: A longitudinal field study
Adopting a longitudinal field study, this paper investigates whether entity theorists (students who believe human attributes are fixed) are less likely than incremental theorists (students who believe human attributes are malleable) to change their evaluations of a teacher in accordance with his behavioral changes. An instructor exhibited some forgetful behaviors in the first half of a course, and ceased doing so in the second half. Consistent with our hypothesis, incremental theorists adjusted their perceptions of the instructor. They rated him as less forgetful accordingly at the end of the course than at the middle. Entity theorists, however, did not show this change. With improved ecological validity, this study extends previous laboratory studies to teacher evaluation. © 2010 Copyright the Authors.

Developing an interactive game platform to promote learning and teamwork on mobile devices: an experience report
In the past few Years, many new development toolkits such as the Nebula2 and/or mobile technologies including the WiFi or mobileTV have opened up exciting learning opportunities on mobile devices. On top of it, new technologies continue to fuel the rapid growth of newly merged fields of research like the edutainment for educational entertainment. In a recent teaching development project, we have developed an interactive game platform to facilitate learning and more importantly the spirit of teamwork for collaborative problem-solving on desktop and pocket PCs. With the great challenges imposed by globalization, we strongly believe that learning to collaboratively analyze and then apply the "appropriate" knowledge to solve a specific problem is always the key to success. In this paper, we discuss about an on-going work, and share our relevant experience in system development. Furthermore, evaluation strategies will be thoroughly examined. After all, our work shed light on many interesting directions for future exploration. © 2008 IEEE.published_or_final_versio
An interactive and pen-based simulator to enhance education and research in computer systems: An experience report
The active uses of simulators to facilitate and/or promote learners’ experience in many applications
has significantly reshaped the latest educational technology or training methodologies in the past
decades including the training of engineering students to understand the actual working mechanisms
of specific engineering principles, or the military officers on tactic planning in a simulated combat
environment. In many cases, it was clearly revealed that the appropriate uses of simulators not only
avoids the indispensable costs of human lives or money lost in the hostile combat or investment field,
but also effectively motivates and/or enhances the learners’ interests in the relevant fields of study,
thus fueling significant impacts on their actual performance. However, many conventional simulators
often require the users to input a formal specification file such as a script or program to specify about
the simulation settings. Besides, even in many Window based simulators, the users may need to
explicitly memorize about the meanings of various system variables and their proper settings before
running a simulation to observe the imparted changes. All these unnecessary hassles will drastically
reduce the interactivity of simulators, and also lower the users’ interests in using them. With the fast
developing tablet and ultra-mobile PCs, we have seen ample opportunities of employing sophisticated
pen-based computing technologies to improve the interactivity of simulators in order to enhance the
learners’ experience to learn, reason or visualize with simulators in more effective ways. Therefore, in
a recent pen-based simulator development project awarded by the Microsoft Research Asia (MSRA),
we proposed to use the Microsoft digital ink library to support fast symbol/character recognition and
the XML technologies to flexibly define various models of computer architectures so as to build an
innovative and pen-based simulator for mobile computing devices. With pen-based or other inputs,
our simulator allows the instructors/students to flexibly add or modify instructions that will generate
live animations to facilitate interactive discussion for teaching undergraduate to postgraduate
courses. Besides, our simulator has the full potential to support research on computer systems
through visualization of new results generated out of new computational models or
optimization strategies. A prototype of our simulator was completed and then released to all
our Year-1 students for trials in the last month in which we collected some initial and positive
feedbacks. A more vigorous evaluation was planned and would be conducted by the end of
this spring semester. All in all, there are many interesting directions for further investigation
including the integration of relevant course materials in the form of digital resources or
pointers to online databases into our simulator, and a careful study of the pedagogical
changes brought by our innovative and pen-based simulator.published_or_final_versio

Change of the emission spectra in organic light-emitting diodes by layer thickness modification
The electroluminescence (EL) and photoluminescence properties of organic light-emitting diodes (LED) were analyzed using layer thickness modification. Investigations show that the EL spectra exhibited significant variation with the increase of the viewing angle. It was found that multiple peak emission could be achieved for a certain range of thickness values. It was concluded that near white emission with CIE coordinates (0.32, 0.43) could be obtained for optimized device thickness.published_or_final_versio
Intussusception trends in Hong Kong children
OBJECTIVES: To assess trends in intussusception and to validate the coding in Hong Kong's computerised discharge information system. DESIGN: Case notes were reviewed for all children under the age of 5 years who had a discharge diagnosis indicating intussusception or a procedure indicating reduction of intussusception during the 6-year period 1 July 1997 through 30 June 2003. RESULTS: Intussusception rates for infants under 1 year of age (108/100,000) and under 5 years of age (38/100,000) were slightly higher than previous estimates (78-100/100,000 and 27-32/100,000, respectively) that used passive discharge data alone. CONCLUSIONS: Hong Kong's passive computer data systems could be used to monitor rates of intussusception after the introduction of new rotavirus vaccines, provided readmissions, inter-hospital transfers, and hospital follow-ups for the same episode are taken into account.published_or_final_versio
