Statistical analysis reveals that urban residents＇ preferred occupations are mainly those in which they themselves are relatively concentrated, such as government officials, teachers, and scientific researchers. Their least preferred occupations are mainly those in which migrant workers are relatively concentrated, such as the construction industry and the hospitality industry. The category of social distance between the two groups is mostly medium or remote. There is a certain level of asymmetry in their evaluations of social distance. social distance is greatly influenced by differences in social status, cultural differences, spatial segregation, and informal institutions. social distance between urban residents and migrant workers has been diminishing continuously, and a degree of social integration between them has occurred.

social distancing during COVID-19 has become one of the most important measures in reducing the risks of the spread of the virus. Implementing thesemeasures at universities is crucial and directly related to the physical attendance ofthe populations of students, professors, employees, and other members on campus. This research proposes an automated scheduling approach that can help universities and schools comply with the social distancing regulations by providingassistance in avoiding huge assemblages of people. Furthermore, this paper proposes a novel course timetable-scheduling scheme based on four main ***, a distance of two meters must be maintained between each student inside theclassroom. Second, no classrooms should contain more than 20% of their regularcapacity. Third, there would be no back-to-back classes. Lastly, no lectures shouldbe held simultaneously in adjacent classrooms. The proposed approach wasimplemented using a variable neighborhood search (VNS) approach with an adaptive neighborhood structure (AD-NS) to resolve the problem of scheduling coursetimetables at Al-Ahlyyia Amman University. However, the experimental resultsshow that the proposed techniques outperformed the standard VNS tested on university course timetabling benchmark dataset ITC2007-Track3. Meanwhile, theapproach was tested using datasets collected from the faculty of information technology at Al-Ahlyyia Amman University (Jordan). Where the results showed that,the proposed technique could help educational institutes to resume their regularoperations while complying with the social distancing guidelines.

为了探究不同调节定向类型的消费者对不同社会距离他人评价的反应，采用2(调节定向：促进VS预防)×2(社会距离：社会远距离VS社会近距离)×2(评价属性：积极VS消极)实验设计的方法，结果发现，促进定向的消费者更愿意接受社会远距离他人的评价，预防定向的消费者更愿意接受社会近距离他人的评价。促进定向的消费者受社会远距离他人的积极评价影响更显著，预防定向的消费者受社会近距离他人的消极评价影响更显著。

基于2007年末对南京市民的问卷资料，从社会距离的角度分析市民对流动儿童的态度及影响因素，研究发现，与市民对流动农民的态度相比，市民对流动儿童的态度分化相对较大；市民对流动农民的态度会再生产或复制到流动儿童群体，不仅产生对流动儿童的歧视和排斥，而且还会映射到流动儿童的认知上，使流动儿童产生自我和社会认知的游离，导致这一群体的边缘性再生产，使其感受着作为“外来人”的身份尴尬和充当边缘人的迷茫心态。

利用囚徒困境范式，考察了合作指数CI(.1～.9)与社会距离(亲密、陌生)对个体合作行为的影响。结果发现，社会距离和合作指数均会对合作行为产生影响，两者的交互效应不显著；合作率会受到合作指数的促进作用，但不会随合作指数的增高立即增长；在CI=.1～.9这9个水平下，亲密被试间的合作率均显著高于陌生被试间的合作率。这一结果说明，合作指数对合作行为的促进作用存在阈值；社会距离缩小可促进个体的合作倾向，并更快地达到合作水平；合作指数与社会距离相互独立地影响合作行为。
