The growth in ageing population globally has led to the increase in demand for retirement or aged care homes. Adopting public–private partnership (PPP) in the global retirement village market has become the new approach to address some of the emerging challenges. This paper aims to explore and analyse the critical success factors (CSFs) for the adoption of PPP in the global retirement village market.

An empirical questionnaire survey was conducted with experienced practitioners in the global PPP and retirement village markets. Mean score analysis, normalization range method, Kendall’s coefficient of concordance and factor analysis were used for analysis.

Results show that out of the 27 CSFs identified, the most significant ones in developing PPP retirement village projects are “the age-friendly design of villages”, “appropriate location of PPP retirement village”, “reliable and accessible health and physical facilities” and “effective social inclusion and integration in villages”. Further analysis shows that the 27 CSFs can be grouped into 7 major factor groupings, namely, “effective project monitoring”, “financial support”, “social integration”, “effective contractual arrangement between parties”, “government commitment and support”, “sustainable design of village” and “effective payment structure”.

The outputs of this study will adequately inform retirement village developers, retirement village stakeholders and local government authorities of the best practices they should put in place to ensure the sustainable growth of the global retirement village market.

The purpose of this paper is to present a transition detector (TD)-based radiation hardened flip-flop (TDRH-FF) for single event upset (SEU).

With SEU recovery and single event transient (SET) detector mechanism, the TDRH-FF can tolerate SEU during hold mode and generate a warning signal for architecture-level recovery during transport mode when input signal contains SET. Evaluation results show that the TDRH-FF outperforms comparable comprehensive performance.

Simulation results show that 1) the mean pulse width of the correction glitches (at full width half maximum) of TDRH-FF is less than 10 ps; 2) the area overhead of TDRH-FF is similar to the EVFERST-FF, BISER-FF and DNURHL-FF; 3) TDRH-FF has the same average power consumption as SETTOF, and moderate PDP and Ps values among these compared FFs.

In this paper, a TD-based TDRH-FF is proposed to solve the problems in the previous design. And the main contributions of the proposed TDRH-FF are summarized: Minimum size transistors are used in the proposed TD which leads to a considerable decrease in area overheads and propagation delay (resulting in an ignorable correction glitch); and compared with other radiation hardened flip-flop, TDRH-FF outperforms comparable comprehensive performance.
