In February 2020, Macau became one of the first regions where the pandemic of coronavirus or Covid-19 affected the totality of social and economic life leading to increased anxieties over movement and distance. Although Macau has had very few actual cases of the virus – 46 in total –and no deaths from it, the Macau government rapidly instituted a lock­ down. The aim of this article is to reflect on how the social experience of being in lockdown can provide insights into understanding the type of experience or condition that we provisionally term ‘anxious immobility.’ Such a condition is characterized by a total disruption of everyday rhythms and specifically anxious waiting for the normalization of activity while being the subject of biosocial narratives of quarantine and socially responsible. The paper is based upon 3 months of ethnographic research conducted by two researchers based in Macau. We also reflect upon some aspects of the politics of mobilities in the light of disruptions and friction points between Hong Kong, Macau, mainland China, and the rest of the world.

Seafloor massive sulfide (SMS) deposits are important deep-sea mineral resources expected to occur predominantly on slow- and ultraslow-spreading mid-ocean ridges. Resource estimates are already available for some of the largest SMS deposits on slow-spreading ridges but not on ultraslow-spreading ridges. Based on geological mapping and sampling, this study investigates the distribution and content of sulfide-rich deposits in the Yuhuang-1 hydrothermal field (YHF), located on the ultraslow-spreading Southwest Indian Ridge. The sulfide-rich deposits in the YHF are composed of two areas ∼500 m apart: the southwest sulfide area (SWS) and the northeast sulfide area (NES). We calculated the volume of sulfide-rich mounds in the YHF and arrived at a total accumulation of ∼10.6 × 106 tons, including at least ∼7.5 × 105 tons of copper and zinc and ∼18 tons of gold. Furthermore, considering the coverage of layered hydrothermal sediment mixed with sulfide-rich breccias, which may have underlying massive sulfide deposits, the maximum total mass was estimated at ∼45.1 × 106 tons. This suggests that the YHF is one of the largest SMS deposits worldwide and confirm that ultraslow-spreading ridges have the greatest potential to form large-scale SMS deposits.

With the fifth generation (5G) communication technology, the mobile multiuser networks have developed rapidly. In this paper, the performance analysis of mobile multiuser networks which utilize decode-and-forward (DF) relaying is considered. We derive novel outage probability (OP) expressions. To improve the OP performance, we study the power allocation optimization problem. To solve the optimization problem, we propose an intelligent power allocation optimization algorithm based on grey wolf optimization (GWO). We compare the proposed GWO approach with three existing algorithms. The experimental results reveal that the proposed GWO algorithm can achieve a smaller OP, thus improving system efficiency. Also, compared with other channel models, the OP values of the 2-Rayleigh model are increased by 81.2% and 66.6%, respectively.

The purpose of this paper is to study compatibility variations in buyer-seller relationships between Mainland Chinese firms and Hong Kong Chinese buyer firms that act as intermediaries to markets in the West. Data are drawn from 19 multiple in-depth case study interviews with Mainland and Hong Kong Chinese firms and buyer firms from the West. Compatibility dimensions that provide further evidence of factors that underpin the nature of classical-type exchange arrangements, vis-à-vis relational relationships, within Chinese buyer-seller interactions are identified. Compatibility variations based on political and legal factors are driven by interpretation and application of Chinese state laws at the business and provincial levels rather than at the national level. Mainland Chinese tend to exhibit authoritative vis-à-vis Confucian-based practices and a short-term orientation within interactions. There is a need to expand the psychic distance composite to elucidate compatibility variations within the distinct provincial business regions of China. Quantitative studies to test for compatibility variability in China business practices across China are needed next. A better understanding of the nature of classical inclinations used by the Chinese is crucial, as is an understanding of how firms, both domestic and foreign, are able to leverage classical and relational relationships within Mainland China. Uncertainty associated with the entrepreneurial behaviours of Chinese businesspersons and a varying emphasis on traditional Confucian values in business result in a hybridisation of interactions across classical and relational types. Guanxi may be evolving beyond traditional social and personal trust as Mainland Chinese business relationships have advanced from the smaller scale CFB stage to the state-owned enterprise stage, and now to the larger and increasingly important world trade stage. The paper challenges shortcomings in research that has centred exclusively on the relational nature of Chinese business interactions, and it builds on previous research to study compatibility variations underpinning these Chinese interactions. It predicts a hybridisation of interactions amongst Chinese actors and provides a foundation for future quantitative research to study compatibility variations, and also classical-type business practices across China. Increased international market awareness may also be leading to the inclusion of an economic trust factor, driving classical-type Chinese buyer-seller relationships, as is more characteristic of arrangements found in Western exchanges.

In Macao, the government has initiated a debate regarding revisions in the Decree Law in order to promote a more inclusive schooling system. In this Special Administrative Region of China, inclusive education is one of three possible types of special education that are likely be legislated in the future. The way the teachers perceive the different aspects related to inclusive education, namely the principles, concepts and law, is essential for its full implementation. The aim of this study is to understand teachers’ perceptions about the proposed amendments in the consultation document for changes in the special education regime. In particular, we focus on teachers’ acceptance of the recommended role of parents, the proposed placement models and expectations for teacher training. A mixed-methods approach with a survey of a sample of 500 teachers in private schools and interviews to a sub-sample of 20 provide the data. While agreeing in principle with the majority of the proposed changes in the Decree Law, there were several reservations made by the teachers, especially regarding the extent of parental choice, placement decisions and teacher training. Recommendations to continue the pathway for a more inclusive education system in Macao and for further research are made.
