Information resource orchestration during the COVID-19 pandemic: A study of community lockdowns in China     

《International Journal of Information Management》2020

The outbreak of the COVID-19 pandemic has created significant challenges for people worldwide. To combat the virus, one of the most dramatic measures was the lockdown of 4 billion people in what is believed to be the largest quasi-quarantine in human history. As a response to the call to study information behavior during a global health crisis, we adopted a resource orchestration perspective to investigate six Chinese families who survived the lockdown. We explored how elderly, young and middle-aged individuals and children resourced information and how they adapted their information behavior to emerging online technologies. Two information resource orchestration practices (information resourcing activities and information behavior adaptation activities) and three mechanisms (online emergence and convergence in community resilience, the overcoming of information flow impediments, and the application of absorptive capacity) were identified in the study.  相似文献

深化开放中产业技术依赖与锁定效应——基于我国葡萄酒产业的实证          下载免费PDF全文

陈强强  窦学诚 《科研管理》2018,39(7):26-33

本文梳理了技术变迁路径依赖或“锁定”的发生过程与形成机制；以中国葡萄酒产业1998-2014年相关数据为样本，运用数据包络分析法测度葡萄酒产业技术进步状况；通过构建计量模型，讨论深化开放中中国葡萄酒产业技术锁定效应及要素资源传导机制。研究表明：（1）中国葡萄酒产业全要素生产率平均增长速度为12.40%，整体技术水平是提升的，生产率增长是技术进步与技术效率变化共同作用的结果；（2）进口贸易对要素资源（物质资本、人力资本）导向作用十分明显。葡萄酒进口每增加1%，物质资本和人力资本的使用分别增加0.35%和0.143%，出口贸易对要素资源配置的弱化作用明显，中国葡萄酒产业国际竞争力低下。（3）葡萄酒产业发展中存在明显的技术锁定效应，且人力资本是技术效率和全要素生产率锁定的主要影响途径。要素资源的提高将有利于中国葡萄酒产业摆脱开放中锁定效应的影响。  相似文献

A case of IgA multiple myeloma: Nutritional perspective in diagnostic testing     

J. I. Anetor  F I Ajose  T. S Akingbola 《Indian journal of clinical biochemistry : IJCB》2005,20(1):193-197

A 64-year-old security guard and longstanding known hypertensive presented with hypertensive heart disease (HHD), weight loss, an enlarged prostate, and a spontaneously fractured rib. Malignancy of the prostate with possible metastases to the ribs was strongly suspected. Biochemical profiling revealed a paraprotein. Other biochemical and hematological correlates that were on hand before serum protein electrophoresis were rather atypical. Paraprotein studies by immunofixation revealed IgA myelomatosis. Unlike previous reports from Caucasians there was normocalcaemia, normal protein level, microcytic hypochromia, low MCHC, cholesterol level at the lower limit of the reference range and normal urea level (in the face of markedly raised creatinine level). Nutritional modulation of the classical laboratory features of this disease may account for the fairly atypical laboratory picture. The need to appreciate the influence of nutritional status on the laboratory (especially biochemical) features of a disease and thus interpretation of diagnostic tests appears of exceptional current importance, given the widening gap in socioeconomic status and the level of poverty between the resource poor and developed countries from which the classical, clinical and laboratory features of most diseases were first described. This case report reminds of the need not only to recognize theoretically the impact of nutritional status on the laboratory characteristics of a disease but of the practical application of the nutritional perspective in the interpretation of diagnostic investigations, especially in nutritionally disadvantaged communities.  相似文献

Dependency structure language model for topic detection and tracking     

Changki Lee  Gary Geunbae Lee  Myunggil Jang 《Information processing & management》2007

In this paper, we propose a new language model, namely, a dependency structure language model, for topic detection and tracking (TDT) to compensate for weakness of unigram and bigram language models. The dependency structure language model is based on the Chow expansion theory and the dependency parse tree generated by a linguistic parser. So, long-distance dependencies can be naturally captured by the dependency structure language model. We carried out extensive experiments to verify the proposed model on topic tracking and link detection in TDT. In both cases, the dependency structure language models perform better than strong baseline approaches.  相似文献   

资源信息学的发展与展望   总被引：2，自引：0，他引：2  

孙九林 《资源科学》2005,27(3):2-8

本文提出了资源信息是资源客体本质、特征和运动规律的属性的基本概念;阐述了系统论和信息论是资源信息学的理论基础,系统工程和信息方法是资源信息学研究的重要方法,计算机等信息技术是它的重要工具的观点;资源信息是资源信息学的研究对象;介绍了资源信息流从产生、传递、控制到应用等的每一个环节的理论、方法、技术等问题;提出了信息综合分析法、资源系统黑箱方法、系统整体优化法、描述方法和推断方法、定性和定量分析法、多维信息环境法等是资源信息学的研究方法;初步确定了资源信息学的学科体系为资源信息学的理论基础、资源信息学的方法论、资源信息学的技术体系、资源信息学的应用和资源信息学的工程体系;文章最后指出了资源信息产生的机理、信息融合、信息挖掘、专家系统、数据仓库、可视化、信息集成技术研究、资源环境模型研究以及资源环境虚拟科研环境构建等问题是当前资源信息学研究的热点问题等.由于资源信息学是一门尚未成熟的学科,有待进一步去探索,故文章中的观点仅供同等们研究时参考,不妥之处,欢迎批评指正.  相似文献
