Burgess Shale–type fossil Lagerstätten provide the best evidence for deciphering the biotic patterns and magnitude of the Cambrian explosion. Here, we report a Lagerstätte from South China, the Qingjiang biota (~518 million years old), which is dominated by soft-bodied taxa from a distal shelf setting. The Qingjiang biota is distinguished by pristine carbonaceous preservation of labile organic features, a very high proportion of new taxa (~53%), and preliminary taxonomic diversity that suggests it could rival the Chengjiang and Burgess Shale biotas. Defining aspects of the Qingjiang biota include a high abundance of cnidarians, including both medusoid and polypoid forms; new taxa resembling extant kinorhynchs; and abundant larval or juvenile forms. This distinctive composition holds promise for providing insights into the evolution of Cambrian ecosystems across environmental gradients.

Agent interaction protocols are usually specified in terms of permissible sequences of messages. This representation is, unfortunately, brittle and does not allow for flexibility and robustness. The commitment machines framework of Yolum and Singh aims to provide more flexibility and robustness by defining interactions in terms of the commitments of agents. In this paper we identify a number of areas where the commitment machines framework needs improvement and propose an improved version. In particular we improve the way in which commitments are discharged and the way in which pre-conditions are specified.

China has undergone massive socio-economic change over the past 30 years. In parallel, there have been huge changes in social and sexual mores. Until the end of the Mao era strict norms prevailed, with sex outside marriage widely regarded as immoral and unacceptable. Detraditionalisation theory describes the abandonment or reconfiguration of the socio-cultural traditions and has been explored widely in Western settings. This study aimed to explore its relevance for China through exploring attitudes towards premarital sex, extramarital sex, same-sex relations and sex work. We conducted semi-structured interviews with 212 men and women aged 18 to 39 in urban and rural areas of three provinces: Zhejiang, Guizhou and Yunnan. Analysis identified emerging themes. Results show varying degrees of acceptance of the four sexual behaviours, with premarital sex seen as common, homosexuality still regarded as unacceptable by the majority but considerable acceptance of commercial sex work as part of male business transactions and social life. China appears to be on a pathway of detraditionalisation with specific Chinese features. This study suggests that the concept of detraditionalisation applies well to non-Western contexts, but the path it takes is culture-specific and relatively unpredictable.

In an effort to mitigate ecological environments and improve human well-being, the Chinese government's largest-ever relocation and settlement programme is underway. Measuring livelihood resilience and further assessing its impact hold the key to strengthening adaptive capacity and well-being in poverty resettlements. Using a household survey of contiguous poor areas in Southern Shaanxi, China, this research proposes a framework to examine livelihood resilience and its impact on livelihood strategies in the context of poverty alleviation resettlement. To provide more comprehensive empirical evidence, we drew on three dimensions of the previously proposed livelihood resilience framework: buffer capacity, self-organizing capacity, and learning capacity. The results show that capital endowments, social cooperation networks, transportation convenience, and skills acquired from education and rural-urban migration can significantly affect the construction of livelihood resilience. The resilience of households that were relocated because of ecological restoration is the highest, followed by households relocated because of disasters; households relocated because of poverty reduction attempts have the lowest resilience. As for indicators of livelihood resilience, physical capital assets and previous work experience play a major role in household livelihood strategies for pursuing non-farming activities, while household size, stable income, social capital, and information sharing result in diversified livelihood strategies. These findings provide policy implications for enhancing livelihood resilience capacities and improving the scope of available livelihood strategies to emerge from the poverty trap and to adapt to the new environment.

Poverty alleviation resettlement (PAR) is China's largest-ever resettlement program and one of China's flagship poverty alleviation initiatives. Resorting to this state-led conversation and development program, the central and provincial governments aim to lift the poor out of the poverty trap and into sustainable livelihoods, by delivering improvements in housing conditions, infrastructure services, public amenities, and living standards. Taking Ankang as an example, this study examines the PAR from the perspective of vulnerability through a household survey conducted in Ankang prefecture of Shaanxi province, China. A total of six townships in Ankang are covered, with 657 valid questionnaires collected. This study shows that there is a difference in exposure, sensitivity, and the adaptive capacity of rural households with different relocation characteristics, hence generating different livelihood vulnerabilities. The PAR generally achieves the target of livelihood vulnerability reduction. Specifically, the project-induced relocation has a significant positive effect on vulnerability, but there is a significant negative correlation between livelihood vulnerability and relocation region, relocation time, and relocation subsidy. Challenges and problems remain to be addressed for the next phases of the PAR, including diminishing the financial burden on those relocated and providing free public transportation services, carrying out community-building programs and updating the household registration institution, balancing the redistribution and sharing of farmland, furnishing assistance measures for employment searches and training in specific skills, and creating an impartial project to safeguard the non-movers from the significant negative impacts on their physical and spiritual dimensions.
