Platform-based customer agility: An integrated framework of information management structure,capability, and culture     

《International Journal of Information Management》2021

Platform-based customer agility is the ability to leverage the voice of the customer on a platform to achieve market intelligence and to explore competitive action opportunities. Prior studies have indicated the critical role of customer agility in enabling the survival and prosperity of contemporary organizations in a turbulent business environment, although how to develop this capability is not answered. The current research attempts to fill this theoretical gap. Drawing on the information management literature, we propose an integrative information management framework to investigate the process of developing customer agility. By conducting a case study of a leading e-commerce platform in China, we identify three types of platform-based customer agility (i.e. reactive customer agility, proactive customer agility, and coactive customer agility) in different phases of the growth of the platform. Furthermore, a process model is developed from the case study. It shows that platform-based customer agility is achieved by establishing information management structure, developing information management capability, and instilling information management culture. This study contributes to the knowledge on customer agility and information management. Detailed recommendations are also provided for potential practitioners.  相似文献   

Dietary restriction (DR) and its advantages     

M. N. Astagimath  Shrinivas B. Rao 《Indian journal of clinical biochemistry : IJCB》2004,19(1):1-5

Dietary restriction (DR) also called dietary control or calorie restriction is reported to have many advantages with regard to human health. It leads to suppression of obesity, mitigates free radicals and increases available antioxidants which are accounted for extending the life span of individuals. DR is also reported to induce synthesis of heat shock proteins in animals as a control mechanism against stress. Further, it is known to play a significant role in decreasing toxicity and lethality due to a variety of toxic chemicals and drugs by stimulating tissue repair damaged by the toxicants leading to restoration of intact organ and its functions. Moreover, extensive work done on animals indicate DR has an important role in suppressing certain types of cancer. In this review an effort is made to highlight the various advantages of DR from the point of human health perspective.  相似文献

Do teams need both hands? An analysis of team process ambidexterity and the enabling role of information technology     

《International Journal of Information Management》2020

As a core organizational resource, business processes are vital for organizational teams. To deal with today’s volatile business environment, organizations need to be ambidextrous in terms of process capabilities. However, little is known about how process ambidexterity, process standardization, and process agility, are enabled by information technology (IT) and related to team-level activities. To fill this gap in the literature, we conducted a field study based on 160 teams of 1081 individuals from seven companies in South Korea. Our results show that IT enables both process standardization and agility, and that a team’s process ambidexterity has a positive effect on inter-team coordination and team innovation, which in turn have a direct impact on team performance. Our findings highlight the importance of process ambidexterity by investigating the enabling role of IT and its outcomes in a team. Our results offer theoretical and practical implications from the perspective of team process ambidexterity.  相似文献

定向运动员反应认知方式特征的研究   总被引：1，自引：0，他引：1  

王翔 《浙江体育科学》2011,33(4)

通过对57名中国定向运动员（男30名,女27名）反应认知方式的测试与分析,发现定向运动员的反应认知方式主要为慢而准确型、快而不准确型和快而准确型,以慢而准确型为主。优秀与一般定向运动员反应认知方式特征的差异主要体现在准确性上,优秀运动员的准确性明显高于一般运动员。优秀定向运动员的反应认知方式主要为慢而准确型和快而准确型。定向运动可能具有要求运动员反应认知方式以准确为主要目标的特征。反应认知方式测试与评价可用于定向运动员的选材、个性化教学与训练。  相似文献   

环境领导力对企业生态创新的影响机制研究     

杨静  仲为国于毅 《科研管理》2021,42(7):108-115

    管理者的环境领导力和环保认知对企业生态创新决策起到决定性作用。然而,关于管理者的环境领导力能否对生态创新产生影响,究竟产生怎样的影响以及其影响机理至今尚未深入探讨。本文基于自然资源基础理论和领导力理论,从高层管理者认知的角度出发,构建了“环境领导力→高管感知→生态创新行为”的心理决策框架,以更好地解释高管的环境领导力对于不同战略姿态的生态创新（被动式生态创新和主动式生态创新）的影响,以及影响的不同路径。通过对248家制造业企业问卷调查,研究结果表明：环境领导力对主动式生态创新存在显著影响;而对被动式生态创新影响没有通过检验。高管的机会感知在环境领导力与主动式生态创新之间存在部分中介效应;而威胁感知在环境领导力与被动式生态创新行为之间存在完全中介效应。  相似文献

Circadian rhythm effect on physical tennis performance in trained male players     

Álvaro López-Samanes  Diego Moreno-Pérez  José L. Maté-Muñoz  Raúl Domínguez  Jesús G. Pallarés  Ricardo Mora-Rodriguez 《Journal of sports sciences》2017,35(21):2121-2128

To determine the effect of circadian rhythm on neuromuscular responses and kinematics related to physical tennis performance, after a standardised warm-up, 13 highly competitive male tennis players were tested twice for serve velocity/accuracy (SVA), countermovement vertical jump (CMJ), isometric handgrip strength (IS), agility T-test (AGIL) and a 10-m sprint (10-m RUN). In a randomised, counter-balance order, tennis players underwent the test battery twice, either in the morning (i.e., AM; 9:00 h) and in the afternoon (i.e., PM; 16:30 h). Paired t-tests were used to analyse differences due to time-of-day in performance variables. Comparison of morning versus afternoon testing revealed that SVA (168.5 ± 6.5 vs. 175.2 ± 6.1 km · h^?1; P = 0.003; effect size [ES] = 1.07), CMJ (32.2 ± 0.9 vs. 33.7 ± 1.1 cm; P = 0.018; ES = 1.46), AGIL (10.14 ± 0.1 vs. 9.91 ± 0.2 s; P = 0.007; ES = 1.23) and 10-m RUN time (1.74 ± 0.1 vs. 1.69 ± 0.1 s; P = 0.021; ES = 0.67) were significantly blunted during the morning testing. However, IS was not affected by time-of-day (P = 0.891). Thus, tennis performance may be reduced when competing in the morning in comparison to early evening. Therefore, coaches and tennis players should focus on schedule the SVA, power, speed and agility training sessions in the afternoon.  相似文献
