Upper secondary school dropout : lessons from central Java province, Indonesia : a dissertation presented in partial fulfilment of the requirement for the degree of Doctor of Philosophy in Economics at Massey University, Manawatū, New Zealand [PDF]

open access: yes, 2017
One of the biggest challenges in educational reform is dealing with the problem of school dropout. It is not merely due to poor grades or bad behaviour or human capital considerations; often it is a more complex problem.

Elephant‐Skin‐Inspired Porous Cementitious Tiles with Programmable Crack Networks for Passive Cooling

open access: yesAdvanced Materials, EarlyView.
Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Matrix Viscoelasticity Regulates Dendritic Cell Migration and Immune Priming

open access: yesAdvanced Materials, EarlyView.
Matrix viscoelasticity is a key mechanical feature of the tumor microenvironment but remains poorly understood in immune regulation. Here, we develop a tunable collagen platform to decouple viscoelasticity from stiffness and show that slow‐relaxing matrices constrain dendritic cell migration by limiting actomyosin‐driven matrix remodeling, thereby ...

Precise Microstructural and Stoichiometric Control Advances Flexible Ag2Te Thin‐Film Thermoelectrics for Wearable Energy Harvesting

open access: yesAdvanced Materials, EarlyView.
Flexible Ag2Te thin films achieving a record‐high mobility of 4756 cm2 V−1 s−1 and a peak power factor of 18.5 µW cm−1 K−2 are developed via precise structural control. The assembled flexible devices demonstrate excellent mechanical stability and ultrafast voltage response, enabling precise thermal detection when integrated into a robotic gripper for ...
