Knowledge creation processes as critical enablers for innovation     

D. Esterhuizen  C.S.L. Schutte  A.S.A. du Toit 《International Journal of Information Management》2012

Knowledge conversion is a prominent theme within the knowledge management field and the question arises how knowledge creation processes can grow innovation capability maturity. This notion provides the platform for aligning knowledge creation processes to the requirements for innovation capability growth from one maturity level to the next. In order to achieve this alignment, the authors identified a knowledge creation path as a key enabler for maturity growth in each innovation capability area. Knowledge management tools and organisational facilitating conditions that support the specific knowledge processes highlighted in the identified path were identified through a literature study and subsequently synthesised to form a framework. This framework provides guidelines for the use of knowledge creation processes as a vehicle to improve innovation. The amount of time needed to practically test the framework does not allow for the practical implementation of the framework and the impact of the framework was demonstrated by discussing a practical organisational scenario.  相似文献

Perspectives on academic staff involvement in the acquisition and implementation of educational technologies     

Laurence Habib  Monica Johannesen 《Teaching in Higher Education》2013,18(5):484-496

This article presents the results of a study using both quantitative and qualitative data to uncover the extent and nature of the involvement of academic staff in the processes of acquisition and implementation of educational technologies. Actor-network theory (ANT) is used to inform the design of the study and the analysis of the data. Three main areas of investigation are (1) issues of institutional policy and overall purpose of technology, (2) issues of staff involvement in various activities related to acquisition and use of technology and (3) issues related to the existence of arenas for dialogue and discussions of technological needs and requirements across organisational boundaries. The analysis focuses on the diffuseness of the role of academic staff in processes of development of institutional policies and technology acquisition. The article concludes with suggestions for organisational policy in higher education contexts, and possible directions for new research.  相似文献

A study on forecasting electricity production and consumption in smart cities and factories     

《International Journal of Information Management》2019

The electrical power sector must undergo a thorough metamorphosis to achieve the ambitious targets in greenhouse gas reduction set forth in the Paris Agreement of 2015. Reducing uncertainty about demand and, in case of renewable electricity generation, supply is important for the determination of spot electricity prices. In this work we propose and evaluate a context-based technique to anticipate the electricity production and consumption in buildings. We focus on a household with photovoltaics and energy storage system. We analyze the efficiency of Markov chains, stride predictors and also their combination into a hybrid predictor in modelling the evolution of electricity production and consumption. All these methods anticipate electric power based on previous values. The main goal is to determine the best method and its optimal configuration which can be integrated into a (possibly hardware-based) intelligent energy management system. The role of such a system is to adjust and synchronize through prediction the electricity consumption and production in order to increase self-consumption, reducing thus the pressure over the power grid. The experiments performed on datasets collected from a real system show that the best evaluated predictor is the Markov chain configured with an electric power history of 100 values, a context of one electric power value and the interval size of 1.  相似文献
