Recent events have renewed attention to how organizations rely on digital resources in response to exogenous shock. Though the literature on organizational resilience indicates that this is best understood as a process through which organizational actors respond to a specific shock, most IS research attends to resilience as an outcome. Against that backdrop, we present a case study of how a university shifted to virtual teaching in response to a government-imposed lockdown during the COVID-19 pandemic. Adopting a digital resourcing perspective allowed us to reveal the organizational resilience process and the way digital resources shaped it. We found that the resilience process unfolded in stages as educators, assisted by students, managers, and IT personnel pivoted, adapted, and normalized into teaching virtually. Across these stages, digital resources took on specific roles as the resilience process progressed from the organization’s pre-shock accumulation of digital resources into its continued digitalization efforts. Based on these findings, we contribute to existing literature by advancing and empirically substantiating a process view of the role of digital resources in organizational resilience.  相似文献

《南通方言疏证》为孙锦标著述四种之一,计四卷五十类,大致以“人事”、“自然”、“生物”为序;释义主要针对《光绪通州志·方言》辨正、溯源、订补;注音包括直音、读若、反切三类;引证广泛,例证丰富;在中国语言学史上有史料价值,在南通方言史研究方面有语料价值,在语词归类、本字考订、音理分析方面有一定的瑕疵。  相似文献

We report that a 63-year-old Chinese female had acute myeloblastic leukemia (AML) in which trisomy 21 (+21) was found as the sole acquired karyotypic abnormality. The blasts were positive for myeloperoxidase, and the immunophenotype was positive for cluster of differentiation 19 (CDI9), CD33, CD34, and human leukocyte antigens (HLA)-DR. The chromosomal analysis of bone marrow showed 47,XX,+21 [2]/46,XX[18]. Fluorescent in situ hybridization (FISH) showed that three copies of AML1 were situated in separate chromosomes, and that t(8;21) was negative. The patient did not have any features of Down syndrome. A diagnosis of CD19-positive AML-M5 was established with trisomy 21 as a sole acquired karyotypic abnormality. The patient did not respond well to chemotherapy and died three months after the diagnosis. This is the first reported case of CD19-positive AM L with trisomy 21 as the sole cytogenetic abnormality. The possible prognostic significance of the finding in AML with +21 as the sole acquired karyotypic abnormality was discussed.  相似文献

男性气概危机是19世纪末历险传奇的复兴与繁荣极为重要的现实原因。历险文本由男性作家创作,以男性为中心,回避女性的影响与干扰,维护男权中心地位,是一种阳刚之气的文学想象。它宣杨一种积极的行动哲学,突出身体的力量,强调男性同盟在男性身份建构中的重要作用。某种意义上,历险传奇的复兴可以视作对19世纪晚期男性身份焦虑做出的文学回应,是讨论、质疑、重建与宣扬男性气概的重要场所。  相似文献

19世纪,我国的语言学研究虽有短暂的辉煌,但研究内容仍没有脱离语文学的范围,属语言学的早期发展阶段。西方各国的学术研究此时已出现现代社会特征:历史比较语言学的理论和方法得到发展和完善,普通语言学出现,新语法学派的理论形成。中外19世纪的语言学研究有同有异,总的说来,异大于同。这个比较给了我们一些关于我国现代语言学如何发展的启示。  相似文献

The COVID-19 pandemic has posed a significant challenge to higher education and forced academic institutions across the globe to abruptly shift to remote teaching. Because of the emergent transition, higher education institutions continuously face difficulties in creating satisfactory online learning experiences that adhere to the new norms. This study investigates the transition to online learning during Covid-19 to identify factors that influenced students' satisfaction with the online learning environment. Adopting a mixed-method design, we find that students' experience with online learning can be negatively affected by information overload, and perceived technical skill requirements, and describe qualitative evidence that suggest a lack of social interactions, class format, and ambiguous communication also affected perceived learning. This study suggests that to digitalize higher education successfully, institutions need to redesign students' learning experience systematically and re-evaluate traditional pedagogical approaches in the online context.

Practitioner notes

What is already known about this topic
  • University transitions to online learning during the Covid-19 pandemic were undertaken by faculty and students who had little online learning experience.
  • The transition to online learning was often described as having a negative influence on students' learning experience and mental health.
  • Varieties of cognitive load are known predictors of effective online learning experiences and satisfaction.
What this paper adds
  • Information overload and perceptions of technical abilities are demonstrated to predict students' difficulty and satisfaction with online learning.
  • Students express negative attitudes towards factors that influence information overload, technical factors, and asynchronous course formats.
  • Communication quantity was not found to be a significant factor in predicting either perceived difficulty or negative attitudes.
Implications for practice and/or policy
  • We identify ways that educators in higher education can improve their online offerings and implementations during future disruptions.
  • We offer insights into student experience concerning online learning environments during an abrupt transition.
  • We identify design factors that contribute to effective online delivery, educators in higher education can improve students' learning experiences during difficult periods and abrupt transitions to online learning.

19世纪的西方步入了一个竞相革新的年代,研究此时期的历史,对深入了解世界民主化历程有着巨大帮助。19世纪初的英国,贵族主导的议会政治体制已不能适应工业革命带来的经济大发展的需要,受到了各阶层的不断挑战。面对可能出现的革命,妥协文化使改革成为解决政治问题的主要手段。1832年议会改革主要对选区的分布和选民的财产资格限制进行了调整,它是一系列民主改革的开端,也是英国迈向大众民主的第一步。  相似文献
