Pengaruh kecerdasan emosi terhadap kesediaan pelajar Sarjana Pendidikan Teknik dan Vokasional bagi menceburi profesion perguruan

Kesediaan bakal pendidik bagi menceburi profesion perguruan adalah amat penting bagi menjamin kualiti sistem pendidikan. Kesediaan ini adalah berkait rapat dengan kecerdasan emosi. Maka, kajian perlu dilakukan untuk melihat pengaruh kecerdasan emosi terhadap kesediaan bakal pendidik. Faktor yang dikaji adalah lima domain kecerdasan emosi Goleman (1998) iaitu kesedaran kendiri, kawalan kendiri, motivasi, empati dan kemahiran sosial, manakala kesediaan dilihat dari aspek sikap dan penguasaan kemahiran. Responden dalam kajian ini adalah 108 pelajar semester akhir, Sarjana Pendidikan Teknik dan Vokasional, Fakulti Pendidikan Teknikal dan Vokasional, Universiti Tun Hussein Onn Malaysia (UTHM). Instrumen yang digunakan adalah soal selidik kecerdasan emosi dan kesediaan guru. Data kajian ini dianalisis menggunakan perisian Statistical Package for Social Sciences (SPSS) versi 16.0 melibatkan statistik deskriptif dan analisis inferensi. Dapatan kajian menunjukkan bahawa tahap penguasaan kecerdasan emosi dan kesediaan di kalangan bakal pendidik adalah tinggi. Terdapat hubungan sederhana kuat antara kecerdasan emosi dan kesediaan bakal pendidik. Ujian regresi pelbagai menunjukkan hanya dua domain kecerdasan emosi iaitu kemahiran sosial dan motivasi yang mempengaruhi kesediaan bakal pendidik dari aspek sikap. Manakala, domain kecerdasan emosi yang mempengaruhi kesediaan penguasaan kemahiran ialah kemahiran sosial, motivasi dan empati. Kajian ini diharapkan dapat memberi sumbangan dalam penambahbaikan kursus latihan perguruan di Fakulti Pendidikan Teknikal dan Vokasional, Universiti Tun Hussein Onn Malaysia (UTHM) khususnya, dan institusi pendidikan lain amnya

A spin dynamics approach to solitonics

It is spatial dispersion which is exclusively responsible for the emergence of exchange interaction and magnetic ordering. In contrast, magneto-crystalline anisotropy present in any realistic material brings in a certain non-linearity to the equation of motion. Unlike homogeneous ferromagnetic ordering a variety of non-collinear ground state configurations emerge as a result of competition among exchange, anisotropy, and dipole-dipole interaction. These particle-like states, e.g. magnetic soliton, skyrmion, domain wall, form a spatially localised clot of magnetic energy. In this paper we explore topologically protected magnetic solitons that might potentially be applied for logical operations and/or information storage in the rapidly advancing filed of solitonics (and skyrmionics). An ability to easily create, address, and manipulate such structures is among the prerequisite forming a basis of -onics technology, and is investigated in detail here using numerical and analytical tools

Electronic transport through domain walls in ferromagnetic nanowires: Co-existence of adiabatic and non-adiabatic spin dynamics

We study the effect of a domain wall on the electronic transport in ferromagnetic quantum wires. Due to the transverse confinement, conduction channels arise. In the presence of a domain wall, spin up and spin down electrons in these channels become coupled. For very short domain walls or at high longitudinal kinetic energy, this coupling is weak, leads to very few spin flips, and a perturbative treatment is possible. For very long domain wall structures, the spin follows adiabatically the local magnetization orientation, suppressing the effect of the domain wall on the total transmission, but reversing the spin of the electrons. In the intermediate regime, we numerically investigate the spin-dependent transport behavior for different shapes of the domain wall. We find that the knowledge of the precise shape of the domain wall is not crucial for determining the qualitative behavior. For parameters appropriate for experiments, electrons with low longitudinal energy are transmitted adiabatically while the electrons at high longitudinal energy are essentially unaffected by the domain wall. Taking this co-existence of different regimes into account is important for the understanding of recent experiments.Comment: 10 pages, 6 figure

The Epidemics of Injecting Drug Use and Blood-Borne Disease: A Public Health Perspective

In this article, the author first examines the mechanism by which blood-borne disease is transmitted through sharing of injection equipment. Thereafter, he presents a public health strategy for reducing multi-person use of contaminated injection equipment. This strategy includes: repealing or modifying current laws and regulations making possession and distribution of sterile injection equipment a criminal offense; implementing syringe exchange programs to expand access to new syringes for users of injection drugs; and counseling, education, and treatment targeted to injecting drug users (IDUs), including those in the prison and health care system. The objective of a public health approach is not to encourage or enable IDUs to obtain and use drugs; public health strategies actively seek to reduce drug use due to its profound adverse effects on physical and mental health. Rather, the public health approach seeks to substantially improve health outcomes for IDUs who cannot or will not stop using drugs

New views of the solar wind with the Lambert W function

This paper presents closed-form analytic solutions to two illustrative problems in solar physics that have been considered not solvable in this way previously. Both the outflow speed and the mass loss rate of the solar wind of plasma particles ejected by the Sun are derived analytically for certain illustrative approximations. The calculated radial dependence of the flow speed applies to both Parker's isothermal solar wind equation and Bondi's equation of spherical accretion. These problems involve the solution of transcendental equations containing products of variables and their logarithms. Such equations appear in many fields of physics and are solvable by use of the Lambert W function, which is briefly described. This paper is an example of how new functions can be applied to existing problems.Comment: 16 pages (revtex4), 3 figures, American J. Phys., in press (2004

Energy Conservative Limit Cycle Oscillations

This paper shows how globally attractive limit cycle oscillations can be induced in a system with a nonlinear feedback element. Based on the same principle as the Van der Pol oscillator, the feedback behaves as a negative damping for low velocities but as an ordinary damper for high velocities. This nonlinear damper can be physically implemented with a continuous variable transmission and a spring, storing energy in the spring when the damping is positive and reusing it when the damping is negative. The resulting mechanism has a natural limit cycle oscillation that is energy conservative and can be used for the development of robust, dynamic walking robots
