“…Otherwise, when required, a monochromator is employed to select the beam energy, with particular attention to the stability of the focal point position while scanning the energy. The sample is typically mounted on a piezostage for high-precision positioning, while an optical microscope coupled to a camera, or to an electron microscope (Yin et al, 2016), is often employed to visualize or locate the ROI (or the sample itself).…”

“…The specification of Motel mirrors 20 and the detail design of this nanoprobe can be found in the report of Yin et al . 21 . The main functions of this beamline include XEOL, TR-XEOL, XRF, XAS, CL, XRD and Bragg ptychography 22 with high spatial and temporal resolution so that in a single probe one can simultaneously obtain the optical, compositional and structural information.…”

The multifunctional hard X-ray nanoprobe at Taiwan Photon Source (TPS) exhibits the excellent ability to simultaneously characterize the X-ray absorption, X-ray excited optical luminescence (XEOL) as well as the dynamics of XEOL of materials. Combining the scanning electron microscope (SEM) into the TPS 23A end-station, we can easily and quickly measure the optical properties to map out the morphology of a ZnO microrod. A special phenomenon has been observed that the oscillations in the XEOL associated with the confinement of the optical photons in the single ZnO microrod shows dramatical increase while the X-ray excitation energy is set across the Zn K-edge. Besides having the nano-scale spatial resolution, the synchrotron source also gives a good temporal domain measurement to investigate the luminescence dynamic process. The decay lifetimes of different emission wavelengths and can be simultaneously obtained from the streak image. Besides, SEM can provide the cathodoluminescence (CL) to be a complementary method to analyze the emission properties of materials, we anticipate that the X-ray nanoprobe will open new avenues with great characterization ability for developing nano/microsized optoelectronic devices.

“…In order to encourage employers to hire locals, the Malaysian government took steps such as freezing the recruitment of migrants and increasing levies for migrant labour (Devadason and Meng, 2014;Yin, 2016). Both steps usually failed as repeated freezing and unfreezing of migrant recruitment happened due to pressures by the public and employers (Devadason and Meng, 2014;Yin, 2016;Chin and Mokhtar, 2017). The increase in the levies increased undocumented migrant labour recruitment by employers directly and indirectly, as the cost of hiring documented migrant labour is more expensive than hiring undocumented migrant labour Yin, 2016).…”

Levy increases also caused repeated amnesty programmes by the government, which in itself gives the wrong message towards undocumented migrants and employersthat they can wait till the next amnesty programme (Devadason and Meng, 2014).…”

International Migration

Labour migration into Malaysia has increased rapidly in recent decades and this has affected Malaysia's government policy in managing migrants’ movement. Interestingly, Malaysia has attracted a high degree of unskilled labour, accompanied by unabated rise of undocumented migrant workers. Mitigating undocumented migration is the main aim of Malaysia's labour migration policy and therefore the focus of Malaysian government. This has impacted on how enforcement agencies work out strategies. These agencies are the forefront of Malaysia's labour migration policy but they faced a number of challenges, such as documentation, finance and manpower capability, and political intervention, which impede their ability to optimize their capabilities in enforcing the Malaysian government labour migration policy. Resolving these challenges and moving towards a long‐term labour migration policy will benefit the Malaysian state, its citizens and the labour migrants.
