Greater Bay Area mainland residents’ evaluation of COVID-19 prevention and city impression of Hong Kong and Macau

Co-founded by Lingnan University and South China University of Technology, “Joint Research Centre for Greater Bay Area - Social Policy & Governance” released a recent survey entitled “Greater Bay Area mainland residents’ evaluation of COVID-19 prevention and city impression of Hong Kong and Macau” on April 16 2020. The result found that mainland residents in Great Bay Area (GBA) believed that their local governments’ epidemic prevention was done better than the Hong Kong and Macau governments

Resident Evaluation and Expectation of Social Services in Guangzhou

China’s welfare system is a typical “residual welfare regime”, which did not manifest too many flaws in the planned economy era. However, economic reform and market-oriented transformations in recent decades have shaken the original well-balanced “residual” and “needs” pattern. The decline of the “work unit system” has led to two consequences: First, it radically transformed the social and economic structures, which gave rise to increased and diversified needs of social welfare. Second, the government is being pressed to shoulder more responsibility for social welfare provisions. This article adopts a case study approach to examine changing social welfare needs and expectations in Guangzhou, a relatively developed city in southern China. With particular focus on the major strategies adopted by the Guangzhou government in addressing people’s welfare needs, this article critically examines how far the new measures have met the changing welfare expectations of citizens in mainland China

Perceptions on the COVID-19 epidemic of the elderly in Hong Kong

The suspension of most of the non-emergency services at public hospitals during the COVID-19 outbreak is a source of worries to senior citizens with chronic illnesses, as they have not been able to attend scheduled medical appointments. A recent survey by Lingnan University (LU) reveals that over 60 per cent of senior citizens are willing or very willing to try online medical consultations when the relevant technology is fully developed

Influence of Range Gate Width on Detection Probability and Ranging Accuracy of Single Photon Laser Altimetry Satellite

The influence of the single photon laser altimeter range-gate width on the detection probability and ranging accuracy is discussed and analyzed, according to the LiDAR equation, single photon detection equation and the Monte Carlo method to simulate the experiment. The simulated results show that the probability of detection is not affected by the range gate, while the probability of false alarm is relative to the gate width. When the gate width is 100 ns, the ranging accuracy can accord with the requirements of satellite laser altimeter. But when the range gate width exceeds 400 ns, ranging accuracy will decline sharply. The noise ratio will be more as long as the range gate to get larger, so the refined filtering algorithm during the data processing is important to extract the useful photons effectively. In order to ensure repeated observation of the same point for 25 times, according to the parameters of ICESat-2, we deduce the quantitative relation between the footprint size, footprint, and the frequency repetition. The related conclusions can provide some reference for the design and the development of the domestic single photon laser altimetry satellite
