This paper investigates the relationship between employees＇ perception of work-family balance practices and work-family conflicts. It examines the role of challenge stress and hindrance stress as moderators. Based on survey data collected from 841 civil servants in Beijing, we found that perceived work-family balance practices may reduce work-family conflict, while challenge and hindrance work stresses were positively related to work-family conflict. In addition, challenge and hindrance stresses differentially moderated the relationship between perceived work-family practices and work-family conflict. When challenge stress is high then workffamily balance practices will reduce work-family conflict. However, under high hindrance stress, work-family balance practices will serve to reduce work-family conflict less. More detailed analysis of the configurational dimensions of work-family balance practices （work flexibility, and employee and family wellness care） are also tested. This study provides additional insight into the management of work-family interfaces and offers ideas for future research.

In recent years,under the stimulation of the national policy and the land circulation policy,the villages and towns have begun to guide the farmers to carry on the land circulation in an orderly way,combine the targeted poverty alleviation with the development of modern agriculture,and drive the registered households to participate in the modern agricultural industry and achieve the goal of getting rid of poverty and getting rich while realizing the transformation and upgrading of agriculture. The transfer of land management right can drive the local employment and the poverty reduction through industrial development is implemented. Taking Mopi Village in Xinping County as an example,this paper analyzes the main methods and effects of the transfer of land management right in this village in promoting poverty reduction through industrial development,and puts forward the existing problems and suggestions.

Whereas biochemical markers are available for most types of cell death, current studies on non-autonomous cell death by entosis rely strictly on the identification of cell-in-cell structures (CICs), a unique morphological readout that can only be quantified manually at present. Moreover, the manual CIC quantification is generally over-simplified as CIC counts, which represents a major hurdle against profound mechanistic investigations. In this study, we take advantage of artificial intelligence technology to develop an automatic identification method for CICs (AIM-CICs), which performs comprehensive CIC analysis in an automated and efficient way. The AIM-CICs, developed on the algorithm of convolutional neural network, can not only differentiate between CICs and non-CICs (the area under the receiver operating characteristic curve (AUC) > 0.99), but also accurately categorize CICs into five subclasses based on CIC stages and cell number involved (AUC > 0.97 for all subclasses). The application of AIM-CICs would systemically fuel research on CIC-mediated cell death, such as high-throughput screening.

Dear Editor,According to the World Health Organization(WHO),as of March 8,2021,the pandemic caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)had infected more than 116 million patients with coronavirus disease 2019(COVID-19)(https://***).The high infectivity of SARS-CoV-2 is largely attributable to the unique sequence composition of its spike(S)glycoprotein.

Dear Editor,By the end of June 2020,the pandemic of coronavirus diseases 2019(COVID-19)had resulted in more than 10 million individuals,all over the world,being infected with the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).1 The high contagiousness of SARS-CoV-2 virus was largely attributed to the relatively unique sequence composition in its spike(S)glycoprotein,which is in charge of the host entry by interacting with its cellular receptor angiotensin-converting enzyme 2(ACE2).2,3 The S glycoprotein can be processed into an N terminal S1 fragment that is responsible for receptor binding,and a C terminal S2 fragment that functions to promote membrane fusion.4 SARS-CoV-2 is a type of single-stranded positive-sense ribonucleic acid(RNA)virus,and an increasing number of mutations were identified across the SARS-CoV-2 genome,including the region encoding S ***,the functional implications of these mutations remain largely unknown,we here reported the mutation analysis of S gene and a functional exploration of the dominant D614G mutation.
