AbstractThis article provides an overview of critical qualitative considerations for Black Liberation Research. The methodological considerations focus on: (a) resistance research as paradigm, (b) researcher positionality, (c) naming Black deprivation as the problem of study, (d) situating Black Liberation as the aim of analysis, and (e) centering emotions as humanizing methods. Taken together, the articles in this special issue provide an example of how Black Liberation Research can support the #BLM movement and simultaneously seek to disrupt Black deprivation in the academy. 相似文献

2020 was an unprecedented year, with rapid and drastic changes in human mobility due to the COVID-19 pandemic. To understand the variation in commuting patterns among the Chinese population across stable and unstable periods, we used nationwide mobility data from 318 million mobile phone users in China to examine the extreme fluctuations of population movements in 2020, ranging from the Lunar New Year travel season (chunyun), to the exceptional calm of COVID-19 lockdown, and then to the recovery period. We observed that cross-city movements, which increased substantially in chunyun and then dropped sharply during the lockdown, are primarily dependent on travel distance and the socio-economic development of cities. Following the Lunar New Year holiday, national mobility remained low until mid-February, and COVID-19 interventions delayed more than 72.89 million people returning to large cities. Mobility network analysis revealed clusters of highly connected cities, conforming to the social-economic division of urban agglomerations in China. While the mass migration back to large cities was delayed, smaller cities connected more densely to form new clusters. During the recovery period after travel restrictions were lifted, the netflows of over 55% city pairs reversed in direction compared to before the lockdown. These findings offer the most comprehensive picture of Chinese mobility at fine resolution across various scenarios in China and are of critical importance for decision making regarding future public-health-emergency response, transportation planning and regional economic development, among others. 相似文献

目的:本实验研究全血白细胞线粒体DNA复制数量(mtDNACN)和血浆炎性细胞因子在膝骨关节炎患者中的变化和其相关性。创新点:探讨了老年(50~80岁)膝骨关节炎患者白细胞mtDNACN和血浆炎性细胞因子水平及二者的关系。方法:分别收集膝骨关节炎组和对照组血液样本并对膝关节评分(Kellgren-Lawren grading)。使用实时定量聚合酶链反应(qRT-PCR)检测相对mtDNACN;使用多重免疫分析(multiplex immunoassay)测定血浆中10种炎性细胞因子水平;应用线性相关、Logistic回归和主成分分析(PCA)揭示骨关节炎白细胞mtDNACN和血浆炎性细胞因子的相关性。结论:血浆中白介素4(IL-4)、IL-6和全血白细胞mtDNACN可能是膝骨关节炎有效的生物标志物;IL-5则对mtDNACN减少具有潜在的影响。 相似文献

Blood samples from 39 patients with acute myocardial infarction and 15 healthy controls were analysed for serum and platelet sialic acid. Serum sialic acid levels in patients with acute myocardial infarction were significantly higher than controls (mean 2.7±0.46 μmol/ml Vs. 1.91±0.17 μmol/ml respectively). Levels of serum orosomucoid, an acute phase reactant, containing sialic acid, were also higher in these patients, suggesting a possible non-specific mechanism of increase in serum sialic acid concentration. In contrast, platelets contained significantly less sialic acid in patients with acute myocardial infarction than control (26.73±1.57 nmol/mg protein and 31.97±2.68 nmol/mg protein respectively). 相似文献

A dialogue-program is described which handles crossreferences within a given set of keywords, author names, journal names and specified reference numbers. It uses the set of basic statements available in a WANG 2200T version which is connected to a floppy-diskette. The program has rather convenient features for editing and processing of literature data. 相似文献

This study examines the experiences of Latina faculty during their doctoral education. Twelve semi-structured interviews were conducted with tenure-track Latina faculty (who primarily self-identified as Chicanas, Latinas, and Mexican Americans) across the west and southwest United States. Resiliency theory was used to help structure and understand the findings. Findings show the nature and experiences of Latinas' resiliency during their doctoral programs in the areas of social competence, problem-solving, autonomy, and sense of purpose. The study concludes with a discussion on how academic leaders and institutional change agents can begin to address the education roadblocks experienced by academic Latinas. 相似文献
