Forms of capital and agency as mediations in negotiating employability of international graduate migrants

This study deployed a qualitative approach to explore an alternative perspective regarding graduate migrants’ employability. Twenty graduate migrants in Australia participated in in-depth interviews. Findings revealed graduate migrants faced various challenges in the target labour market, and to successfully secure employment it was important for them to develop key forms of capital – i.e., excellent technical knowledge, relationships with ‘significant others’, strong career identity and psychological resilience, and exercise agency in interlinking these capitals so that they could make use of their strengths and coat weaknesses. Results from the study imply that managing, teaching, and professional staff members should collaborate closely to develop well-rounded programmes to sufficiently equip international students with multidimensional resources.     

A numerical study on the dynamics of droplet formation in a microfluidic double T-junction

In this study, droplet formations in microfluidic double T-junctions (MFDTD) are investigated based on a two-dimensional numerical model with volume of fluid method. Parametric ranges for generating alternating droplet formation (ADF) are identified. A physical background responsible for the ADF is suggested by analyzing the dynamical stability of flow system. Since the phase discrepancy between dispersed flows is mainly caused by non-symmetrical breaking of merging droplet, merging regime becomes the alternating regime at appropriate conditions. In addition, the effects of channel geometries on droplet formation are studied in terms of relative channel width. The predicted results show that the ADF region is shifted toward lower capillary numbers when channel width ratio is less than unity. The alternating droplet size increases with the increase of channel width ratio. When this ratio reaches unity, alternating droplets can be formed at very high water fraction (wf = 0.8). The droplet formation in MFDTD depends significantly on the viscosity ratio, and the droplet size in ADF decreases with the increase of the viscosity ratio. The understanding of underlying physics of the ADF phenomenon is useful for many applications, including nanoparticle synthesis with different concentrations, hydrogel bead generation, and cell transplantation in biomedical therapy.
