Articulation of medium of instruction politics in the Malaysian Chinese press

In postcolonial multilingual societies, matters of education are deeply rooted in the discourse of ethnicity. In Malaysia, the interface between ethnicity and education is reflected in recent debates on the choice of medium of instruction (MOI). In 2002, the Malaysian government introduced English as MOI by replacing Malay, the national language, for teaching mathematics and science, at the school level. However, in 2009, the policy was reversed to Malay. This policy initiative has been actively contested in the Malaysian media. Through an analysis of news reports on the controversy published by the Malaysian Chinese newspaper, Nanyang Siang Pao, this paper aims to illustrate how a sizeable ethnic minority is able to position itself vis-à-vis a national policy. To explain the ethno-political construction of MOI debates in the newspaper, we use two concepts, namely, ‘plurality of struggles’ (Laclau, 2006a, 2006b; Laclau & Mouffe, 1985) and ‘transmission of the speech of others’ (Bakhtin, 1981). These notions are contextualized in the macro-context of a multi-ethnic polity in which Chinese society, Chinese press and Chinese education are seen to co-construct community interests.  相似文献   

MitraClip: a novel percutaneous approach to mitral valve repair     

Jilaihawi H  Hussaini A  Kar S 《Journal of Zhejiang University. Science. B》2011,12(8):633-637

As life expectancy increases, valvular heart disease is becoming more common. Management of heart disease and primarily valvular heart disease is expected to represent a significant proportion of healthcare provided to the elderly population. Recent years have brought a progression of surgical treatments toward less invasive strategies. This has given rise to percutaneous approaches for the correction of valvular heart disease. Percutaneous mitral valve repair using the MitraClip system (Abbott Vascular, Santa Clara, CA, USA) creates a double orifice and has been successfully used in selected patients with mitral regurgitation. We review the rationale, procedural aspects, and clinical data thus far available for the MitraClip approach to mitral regurgitation.  相似文献

Kinematic and EMG activities during front and back squat variations in maximum loads     

Hasan Ulas Yavuz  Deniz Erdağ  Arif Mithat Amca  Serdar Aritan 《Journal of sports sciences》2015,33(10):1058-1066

The aim of this study was to compare the musculature activity and kinematics of knee and hip joints during front and back squat with maximal loading. Two-dimensional kinematical data were collected and electromyographic activities of vastus lateralis, vastus medialis, rectus femoris, semitendinosus, biceps femoris, gluteus maximus and erector spinae were measured while participants (n = 12, 21.2 ± 1.9 years old) were completing front and back squat exercises with maximum loading. Paired sample t-test was used for comparisons between two techniques. Results showed that the electromyographic activity of vastus medialis was found to be greater in the front squat compared to the back squat during the ascending phase (P < 0.05, d = 0.62; 95% CI, ?15.0/?4.17) and the whole manoeuvre (P < 0.05, d = 0.41; 95% CI, ?12.8/?0.43), while semitendinosus (P < 0.05, d = ?0.79; 95% CI, 0.62/20.59) electromyographic activity was greater in the back squat during the ascending phase. Compared to the front squat version, back squat exhibited significantly greater trunk lean, with no differences occurring in the knee joint kinematics throughout the movement. Results may suggest that the front squat may be preferred to the back squat for knee extensor development and for preventing possible lumbar injuries during maximum loading.  相似文献

HILS setup of dynamic flight path planning in 3D environment with flexible mission planning using Ground Station     

M.A. Al-Jarrah  M.M. Hasan 《Journal of The Franklin Institute》2011,348(1):45-65

This paper reports the creation of the HILS setup to simulate the performance of the AUS-UAV system and the Ground Station. The paper will give an overview of the integration of the Ground Station created using a guide, the Avionics Unit created using an embedded system, integrated with various sensors, and the simulator created using simulink/flight simulator combination. The simulation will show the Ground Station and the embedded system working cooperatively to guide the UAV through several mission waypoints in three dimensions (3D). The paper focuses on the algorithm used to create paths in 3D, and also the organization of waypoints to achieve a specific goal. The paper also details the testing of the HILS.  相似文献   

Elementary teachers’ perceptions about the effective features of explicit-reflective nature of science instruction     

Elif Adibelli-Sahin  Hasan Deniz 《International Journal of Science Education》2013,35(6):761-790

ABSTRACT

This qualitative study explored elementary teachers’ perceptions about the effective features of explicit-reflective nature of science (NOS) instruction. Our participants were four elementary teachers from a public charter school located in the Southwestern U.S.A. The four elementary teachers participated in an academic year-long professional development about NOS which consisted of NOS training and NOS teaching phases. After each phase of the professional development, we specifically asked our participants which features of the explicit-reflective NOS instruction they found effective in improving their NOS conceptions by presenting pre- and post-profiles of their NOS conceptions. We identified nine features perceived by the participants as effective components of explicit-reflective NOS instruction: (1) specific focus on NOS content, (2) participation in hands-on NOS activities, (3) introductory NOS readings, (4) multiple types/forms of reflection, (5) multiple exposure to NOS content, (6) structural consistency in the presentation of NOS content, (7) the evaluation of secondary NOS data from elementary students, (8) the analysis of national and state science standards in terms of NOS content, and (9) NOS teaching experience.  相似文献   

Effects of pelvis-shoulders torsional separation style on kinematic sequence in golf driving     

Ki Hoon Han  Christopher Como  Jemin Kim  Cheng-Ju Hung  Mohammad Hasan 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(6):663-685

The golfer’s body (trunk/arms/club) can be modeled as an inclined axle-chain system and the rotations of its parts observed on the functional swing plane (FSP) can represent the actual angular motions closely. The purpose of this study was to investigate the effects of pelvis-shoulders torsional separation style on the kinematic sequences employed by the axle-chain system in golf driving. Seventy-four male skilled golfers (handicap ≤ 3) were assigned to five groups based on their shoulder girdle motion and X-factor stretch characteristics: Late Shoulder Acceleration, Large Downswing Stretch, Large Backswing Stretch, Medium Total Stretch, and Small Total Stretch. Swing trials were captured by an optical system and the hip-line, thorax, shoulder-line, upper-lever, club, and wrist angular positions/velocities were calculated on the FSP. Kinematic sequences were established based on the timings of the peak angular velocities (backswing and downswing sequences) and the backswing-to-downswing transition time points (transition sequence). The backswing and transition sequences were somewhat consistent across the groups, showing full or partial proximal-to-distal sequences with minor variations. The downswing sequence was inconsistent across the groups and the angular velocity peaks of the body segments were not significantly separated. Various swing characteristics associated with the separation styles influenced the motion sequences.  相似文献

Vocational Schools in Turkey: An Administrative and Organizational Analysis     

Hasan Simsek  Ali Yildirim 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2000,31(4):327-342

The data used in this paper were derived from a larger project which had the aim of critically evaluating the Turkish vocational education system on a number of different levels. This article examines the administrative and organisational practices in a selected group of secondary vocational schools in Turkey from the point of view of school administrators, teachers and industrial managers. The results indicate that the Turkish vocational education system is characterised by a centralised, top-down bureaucracy, which inhibits innovative capacity. The authors argue that a degree of decentralisation is necessary at various levels of the system.  相似文献
