Evidence and benefits of postgraduate international students-staff members partnership in extra-curricular activities: a Malaysian perspective

ABSTRACT

The student engagement concept has been revolutionised so that students play an active role alongside staff members in determining their student learning experiences. Although the development of student–staff partnerships enhances student engagement and experience, empirical research on partnerships in Malaysia is scant. This paper contributes to the growing scholarly literature on such partnerships – in particular, exploring postgraduate international students and staff members’ partnership dimensions in extra-curricular activities at a research university in Malaysia. This qualitative study interviewed 33 postgraduate international students, 10 academic staff and 12 professional staff members. Based on the findings, the student–staff partnership model is well integrated into the extra-curricular activities: international students are invited to co-design and implement adjustment programmes for newly arrived international students. This paper also explores the multi-layered benefits of partnerships for postgraduate international students and for staff members. The implications of such partnerships for the university, international students and staff members are discussed.     

Incidental learning in mentally retarded children

Incidental learning of film content was investigated in institutionalized retarded children. In the first of two studies, 40 retardates at six IQ levels, three MA levels, and five CA levels were tested. In the second study, 21 Down's Syndrome, organic, and familial retardates were tested. The stimuli consisted of an 8‐minute film which was shown individually. All subjects were questioned on twenty incidental aspects of the film. In Experiment 1, a curvilinear relationship was found between incidental learning and IQ. Incidental learning improved with MA. A retest, taken 120 hours later, revealed a 10.9 percent loss of incidental learning. Higher IQ children showed the greatest loss. Experiment 2 reported no difference in incidental learning as a function of etiology of retardation. A retest showed a short term memory deficit in organic retardates and a significant loss of incidental learning in Down's Syndrome and familial retardates. Implications of these results were discussed in terms of structured teaching techniques.     

Critical Literacy Strategies for Environmental Educators

This paper seeks to extend the range of critical literacy strategies that environmental educators might use in their engagement with curriculum policies. The paper focuses on a recent curriculum and professional development project from Australia as the context to illuminate and explicate particular critical reading strategies. Specifically, the paper introduces several critical reading strategies by applying them to an evaluation of the Global Education Project's review of global perspectives in curriculum policies from around Australia.     

Evaluation of Oxidative Stress and Antioxidant Status in Pregnant Anemic Women

The present study was conducted to investigate the oxidant–antioxidant status in iron deficient pregnant anemic women. One hundred thirty pregnant women with iron deficiency anemia (IDA) were divided into three groups, namely mild (50), moderate (50) and severe (30) anemic along with pregnant healthy women as controls (50). The complete blood count, plasma lipid peroxidation products, enzymatic and non-enzymatic antioxidants were measured according to respective protocols. The levels of complete blood count, iron, ferritin along with antioxidant enzymes namely catalase, superoxide dismutase, glutathione peroxidase, glutathione reductase and reduced glutathione were significantly reduced in all IDA groups. However, the level of oxidized glutathione, lipid peroxides, protein carbonyls, conjugated dienes were found significantly increased in all anemic patients. Antioxidant vitamins, namely C, E and A were also found significantly decreased in IDA patients. On the basis of our results, it may be concluded that IDA tends to increase the pro-oxidant components, which may result in various complications including peroxidation of vital body molecules resulting in increased risk for pregnant women as well as fetus.     

An inexpensive microfluidic device for three-dimensional hydrodynamic focusing in imaging flow cytometry

We present design, characterization, and testing of an inexpensive, sheath-flow based microfluidic device for three-dimensional (3D) hydrodynamic focusing of cells in imaging flow cytometry. In contrast to other 3D sheathing devices, our device hydrodynamically focuses the cells in a single-file near the bottom wall of the microchannel that allows imaging cells with high magnification and low working distance objectives, without the need for small device dimensions. The relatively large dimensions of the microchannels enable easy fabrication using less-precise fabrication techniques, and the simplicity of the device design avoids the need for tedious alignment of various layers. We have characterized the performance of the device with 3D numerical simulations and validated these simulations with experiments of hydrodynamic focusing of a fluorescently dyed sample fluid. The simulations show that the width and the height of the 3D focused sample stream can be controlled independently by varying the heights of main and side channels of the device, and the flow rates of sample and sheath fluids. Based on simulations, we also provide useful guidelines for choosing the device dimensions and flow rates for focusing cells of a particular size. Thereafter, we demonstrate the applicability of our device for imaging a large number of RBCs using brightfield microscopy. We also discuss the choice of the region of interest and camera frame rate so as to image each cell individually in our device. The design of our microfluidic device makes it equally applicable for imaging cells of different sizes using various other imaging techniques such as phase-contrast and fluorescence microscopy.
