Classroom research as teacher-researcher

In the field of education, research projects that involve both the researcher and teacher being the same person are common today, as attested by the significant number of teacher-researcher studies. One issue confronting the dual role of teacher-researcher is the nature of interaction between the underlying goals that come with each of these roles. There are some researchers who express concern that the combination of these goals within the teacher-researcher may compromise either or both of the work of teaching and research in an unproductive way. This paper is an account of my adventure in attempting to fulfil both teaching and research goals in my work as teacher-researcher in a year 7 (Secondary One) geometry class in Singapore. My experience is then re-interpreted in the context of the ongoing conflicting-versus-complementary talk on the interaction between teacher/researcher &lsquo;selves&rsquo;. A model is proposed to account for the seemingly opposite sides of the camp as reported in the literature on this issue.<br /

Repeat-Until-Success Quantum Computing

We demonstrate the possibility to perform distributed quantum computing using only single photon sources (atom-cavity-like systems), linear optics and photon detectors. The qubits are encoded in stable ground states of the sources. To implement a universal two-qubit gate, two photons should be generated simultaneously and pass through a linear optics network, where a measurement is performed on them. Gate operations can be repeated until a success is heralded without destroying the qubits at any stage of the operation. In contrast to other schemes, this does not require explicit qubit-qubit interactions, a priori entangled ancillas nor the feeding of photons into photon sources.Comment: 5 pages, 2 figures, v3: substantially revised, v4: typos correcte

Malmquist Indices of Pre and Post-Deregulation Productivity, Efficiency and Technological Change in the Singaporean Banking Sector

By the end of the 1990s, the Singaporean government had recognised the need to open up its banking sector so as to remain competitive in the global economy. The Monetary Authority of Singapore thus began deregulation of the banking sector in 1999 to strengthening the competitiveness of local banks relative to their foreign competition through mergers. This paper employs a nonparametric Malmquist productivity index to provide measure of productivity, technological change and efficiency gains over the period 1995-2005. The findings reveal some total factor productivity growth associated with deregulation and scale efficiency improvement largely from mergers amongst the local banks.Efficiency, productivity; deregulation; Malmquist indices; banking

Continuing professional development for RMIT International University Vietnam library staff: Adding value through an international partnership: A case study

The aim of this study was to explore the effectiveness of blended learning - the fusion of face-to-face and online learning experiences - to implement an effective and culturally sensitive program of professional development in an Australian university working in a developing country. It sought insight into pertinent pedagogical approaches for staff development across multiple locations including across national boundaries. The project demonstrated how learners can develop new capabilities and approaches by building on existing skills and knowledge as they interact in communities of practice. The immediate purpose was to design and deliver a continuing professional education program to meet the needs of librarians working at RMIT International University Vietnam in the context of the demands of the academic community and in the light of the challenge library staff experienced in seeking to meet explicit and tacit expectations. The project ran from late January to mid December 2010. The research questions were: &#039;Is blended learning effective as an approach to continuing professional development when working across cultures in a multinational organization?&#039; and &#039;What contribution do face-to-face and online components make to learning outcomes?&#039; The methodology used was an action learning approach. A 2009 consultant&#039;s report into the RMIT Vietnam Library established professional developmental needs which were further detailed in February 2010 by the project leader from RMIT University, Melbourne using a skills audit. Workshops in Vietnam, visits to Melbourne by several Vietnam staff members, and an online forum were then delivered

Protozoan Free Colonies of Lepidoptera

A method for the establishment and maintenance of colonies of Lepidoptera which are free of contamination with protozoa is provided. The colonies consists of individuals capable of breeding and producing viable, noncontaminated butterflies

Haze in the Klang Valley of Malaysia

Continuous measurements of dry aerosol light scattering (Bsp) were made at two sites in the Klang Valley of Malaysia between December 1998 and December 2000. In addition 24-h PM2.5 samples were collected on a one-day-in-six cycle and the chemical composition of the aerosol was determined. Periods of excessive haze were defined as 24-h average Bsp values greater than 150 Mm-1 and these occurred on a number of occasions, between May and September 1999, during May 2000, and between July and September 2000. The evidence for smoke being a significant contributor to aerosol during periods of excessive haze is discussed and includes features of the aerosol chemistry, the diurnal cycle of Bsp, and the coincidence of forest fires on Sumatra during the southwest (SW) monsoon period, as well as transport modelling for one week of the southwest Monsoon of 2000. The study highlights that whilst transboundary smoke is a major contributor to poor visibility in the Klang Valley, smoke from fires on Peninsular Malaysia is also a contributor, and at all times, the domestic source of secondary particle production is present

Biomarkers in acute myocardial infarction

Myocardial infarction causes significant mortality and morbidity. Timely diagnosis allows clinicians to risk stratify their patients and select appropriate treatment. Biomarkers have been used to assist with timely diagnosis, while an increasing number of novel markers have been identified to predict outcome following an acute myocardial infarction or acute coronary syndrome. This may facilitate tailoring of appropriate therapy to high-risk patients. This review focuses on a variety of promising biomarkers which provide diagnostic and prognostic information
