Business Intelligence Capabilities and Firm Performance: A Study in China     

《International Journal of Information Management》2021

The development of artificial intelligence (AI) technology expands the boundary of business practice, inducing the emergence and application of business intelligence (BI) that has promoted the transformation of information techniques to optimize business decision and operation. However, there is a lack of theoretical consensus and measurement of the technology embedded in BI at present. This study exploratively develops the Sense-Transform-Drive (STD) conceptual model of BI based on dynamic capabilities theory and organizational evolutionary theory to explain the core BI capabilities. By using factoring analysis and structural equation modeling analysis, we extract the latent constructs and empirically verify the validity of the STD model and further examine the correlation and mode of interaction of the three core BI capabilities and the impact of BI application on firm performance in the real economy with a sample contextual to Chinese business practices. The study results show that there are direct and high-intensity cumulative positive effects among the structural components of the STD conceptual model and BI-related dynamic capabilities can enhance operating efficiency and firm performance.  相似文献   

基于对应分析模型原理的户外运动安全风险研究     

欧雅怡  刘〓亚  马逢伯 《广州体育学院学报》2017,37(2):43-48

通过对我国2001年至2014年期间,258个户外运动安全事故案例的统计和分析,结合国内外相关研究,建立户外运动安全风险分析框架,将户外运动安全风险划分为4个维度,18个因素指标.根据对应分析模型原理,深入研究户外运动中季节、月份与时段风险的对应性关系,R(3.2.0)软件运行结果显示:户外运动中,凌晨和晚上的风险指数最高;春季、秋季的上午和下午时段,可能存在的伤亡风险几率较高;5月、9月、10月的上午和晚上,3月、6月、11月、12月的下午,1月和4月的凌晨时段,可能存在的伤亡风险几率更高.使用Minitab软件,根据累积贡献率80％以上为主要因素的帕累托原则得到8个主要风险因素和7个次要风险因素.  相似文献   

Kinship,Camaraderie and Contestation: Fāṭimid Relations with the Ashrāf in the Fourth/Tenth Century.     

Shainool Jiwa 《Al-Masaq: Islam & the Medieval Mediterranean》2016,28(3):242-264

The founding of the Fā?imid caliphate across the southern Mediterranean, and then in Egypt, Syria and the ?ijāz at the turn of the fourth/tenth century, necessitated its negotiation with the ashrāf, those who claimed lineal descent from the Prophet Mu?ammad, and who by this time had gained significant influence as a social class based on their charismatic descent. While other dynastic powers fostered relationships with various members of the ashrāf, the Fā?imid–ashrāf dynamics were distinctive in that the Fā?imids legitimised their rule as Ismā?īlī Shī?ī imām-caliphs, based on their claim of descent from the Prophet Mu?ammad, and as the sole successors to his authority and leadership over the Islamic world. Consequently, Fā?imid–ashrāf relations were permeated by fraternal camaraderie as well as by competing contestations based on their shared claim to Prophetic lineage.  相似文献   

父母教养方式对大学生子女体重指数和身体活动行为的影响研究          下载免费PDF全文

尚博睿 《河北体育学院学报》2019,33(4):74-79

运用问卷调查法和数理统计法，对176名大学生及其父母的饮食、身体活动及教养方式进行调查分析。结果显示，子女同父母在体重指数（BMI）上具有显著正相关关系（r=19，P＜05），而在每周平均身体活动量上无显著相关（r=08，P=17）。回归分析表明，三类教养方式对子女BMI均无直接预测作用，然而专制型父母教养方式对父母与子女BMI的相关关系起间接调节作用（P＜01）；在子女身体活动行为方面，溺爱型父母教养方式更有可能导致子女的身体活动不足（P＜01）。研究结果表明，大学生离开家庭环境后，父母教养方式仍然对子女BMI和身体活动行为产生持续影响，父母与子女BMI方面存在相关关系。为今后在青少年肥胖干预及身体活动促进研究中纳入教养方式因素提供了实证依据。  相似文献   

系统论视角下广东省广场体育文化评价指标体系研究     

韩〓晗  杜熙茹 《广州体育学院学报》2017,37(5):51-55

在阅读和梳理中外相关研究文献的基础上,初步提出广东省广场体育文化指标体系.采用特尔斐法,通过三轮专家问卷调查,吸取了专家们的意见和建议,对指标体系不断进行修改和完善,通过因子分析法进一步对其检验,最终确立广东省广场体育文化指标体系,包括广场体育物质文化、广场体育制度文化、广场体育精神文化和广场体育行为文化,4个一级指标、10个二级指标和32个三级指标.该指标已在广东省个案广场调查中应用,结果显示,这套指标设置合理,便于操作,适合我省广场体育文化建设调查和分析,对推动广场体育文化建设和促进全民健身活动开展将具有重要价值.  相似文献   

技术进步、技术效率与中国渔业增长分析   总被引：3，自引：0，他引：3  

席利卿  彭可茂 《中国科技论坛》2010,(3)

本文运用DEA的马姆奎斯特指数法,测定了我国1999—2007年29个省(市、自治区、直辖市)渔业的全要素生产率及其分解的技术效率、纯技术效率、技术进步指数、规模效率,并且对省际间渔业的经济趋同效应进行分析。结论表明:渔业全要素生产率增长显著,沿海地区和内陆地区TFP的增长模式不同,沿海地区以技术进步为主,忽视了技术效率,内陆地区技术进步和技术效率同时发展。TFP促使沿海和内陆各省渔业出现趋同趋势,而TFP的分解指数在全国、沿海和内陆省际间对趋同效应的影响各不相同。  相似文献   

Exploring Verbal,Visual and Schematic Learners' Static and Dynamic Mental Images of Scientific Species and Processes in Relation to Their Spatial Ability     

Sulaiman M. Al-Balushi 《International Journal of Science Education》2013,35(3):460-489

The current study compared different learners’ static and dynamic mental images of unseen scientific species and processes in relation to their spatial ability. Learners were classified into verbal, visual and schematic. Dynamic images were classified into: appearing/disappearing, linear-movement, and rotation. Two types of scientific entities and their related processes were investigated: astronomical and microscopic. The sample included 79 female students from Grades 9 and 10. For the purpose of the study, three instruments were used. The Mental Images by Guided Imagery instrument was designed to investigate participants' visualization of static and dynamic mental images. The Water-Level Task was adopted to estimate participants' spatial ability. The Learning Styles Inventory was used to classify participants into verbal, visual and schematic learners. The research findings suggest that schematic learners outperformed verbal and visual learners in their spatial ability. They also outperformed them in their vividness of microscopic images; both micro-static and micro-dynamic images; especially in the case of appearing/disappearing images. The differences were not significant in the case of astronomical images. The results also indicate that appearing/disappearing images received the least vividness scores for all three types of learners.  相似文献   

高校人才集聚绩效评价方法探析:集聚指数的编制与应用   总被引：1，自引：0，他引：1  

田凌晖 《教师教育研究》2007,19(2):45-49

优秀人才的集聚是高校核心竞争力提升的首要前提,而如何考量高校人才集聚的绩效成为亟待解决的难题。本研究运用统计指数相关方法编制了高校人才集聚指数作为绩效评价的一种方法,并进一步选择位于东北、西北、中部、东部和东南的5所“985”高校,对其2000年以来人才集聚指数进行测算,通过分析测算结果发现五所高校的人才流动均呈逐步优化的发展态势,且发展态势相对稳健,但高校间人才集聚绩效存在一定差异,而差异幅度在一段时间内表现得相对稳定。  相似文献
