Narrative approaches to the transfer of organisational knowledge     

N A D?ConnellEmail author  Jonathan H?Klein  Edgar?Meyer 《知识管理研究与实践》2004,2(3):184-193

Narratives, or stories, have been identified as one of the ways in which knowledge might be transferred, shared or exchanged in organisational settings. Beyond their identification, little consideration has been given to the ways in which narrative approaches can increase our understanding of the creation and dissemination of knowledge in organisations. This paper reflects upon some of the ways in which narrative approaches might contribute towards a better understanding of organisational knowledge management. It contributes to the debate on the nature and significance of the contextual features of organisational knowledge, particularly the role of tacit knowledge, and identifies some of the distinctions between formal and informal knowledge transfer mechanisms, which operate (with or without effective management) within organisations.  相似文献   

Discrete-time recurrent high order neural networks for nonlinear identification     

Alma Y. Alanis  Edgar N. Sanchez  Esteban A. Hernandez 《Journal of The Franklin Institute》2010,347(7):1253-1265

This paper focuses on the problem of discrete-time nonlinear system identification via recurrent high order neural networks. It includes the respective stability analysis on the basis of the Lyapunov approach for the NN training algorithm. Applicability of the proposed scheme is illustrated via simulation for a discrete-time nonlinear model of an electric induction motor.  相似文献

Teachers' ratings vs standardized tests: An empirical investigation of agreement between two indices of achievement     

Christopher F. Sharpley  Elizabeth Edgar 《Psychology in the schools》1986,23(1):106-111

The degree of correlation between teachers' ratings of vocabulary, comprehension, mathematics, and verbal intelligence with scores from the Progressive Achievement Tests (PAT) plus the Peabody Picture Vocabulary Test-Revised (PPVT-R) was assessed with 120 boys and 110 girls aged 8.6 to 10.5 years in three southeastern suburban state schools in Melbourne. Teachers' ratings of students' general attitude also were collected. While results indicated that significant correlations did exist between data from the two sets of measures, these accounted for only small amounts of the total variance, suggesting that two almost discrete domains of information were being tapped. The need for reconciliation between these two domains is discussed and the presence of sex bias in teachers' ratings is raised for further study.  相似文献   

Intermingling and bumpiness: Exploring meaning making in the discourse of a science classroom     

Maria Varelas  Edgar Pineda 《Research in Science Education》1999,29(1):25-49

In this study we capture and analyse in qualitative terms the conversational rhythm—the ebb and the flow of meaning making—in a Year 5 class in order to understand when and how teacher and students succeed in developing shared understandings, and when and how they encounter difficulties. We use the two contrasting concepts of intermingling and bumpiness to catch the phenomenological aspect of time in the science class, which is constituted by the voices of the teacher and the students as they come together to construct disciplinary knowledge. It is a collaborative action research that sheds light on the struggles and possibilities that arise in a science class as a teacher enacts a socio-cultural perspective and engages his students in collecting and analysing experimental data and reasoning through a particular model.  相似文献

An IT-based teaching model for a new generation of students     

Serna M.  Edgar  Serna A.  Alexei 《Journal of Educational Change》2021,22(4):457-474

To demonstrate whether individuals of the new generation have developed a unique and different learning model, research was conducted on children aged 10–11 in England, the United States, Australia and Germany. The qualities and the characteristics those children seek in the activities with which they spend more time were recognized. Using this knowledge, an innovative IT-based teaching model was structured and applied to an experimental group during the 2016–2017 school year. The results show that children indeed have developed their own learning model to extract the information they need from everything that catches their attention, challenges them and offers them rewards. In addition, they easily lose attention and interest when they are subjected to the traditional teaching model, as evidenced in the control group.

Inverse optimal neural control of blood glucose level for type 1 diabetes mellitus patients     

Blanca S. Leon  Alma Y. Alanis  Edgar N. Sanchez  Fernando Ornelas-Tellez  Eduardo Ruiz-Velazquez 《Journal of The Franklin Institute》2012,349(5):1851-1870

In this paper, inverse optimal neural control for trajectory tracking is applied to glycemic control of type 1 diabetes mellitus (T1DM) patients. The proposed control law calculates the adequate insulin delivery rate in order to prevent hyperglycemia and hypoglycemia levels in T1DM patients. Two models are used: (1) a nonlinear compartmental model in order to obtain type 1 diabetes mellitus virtual patient behavior, and (2) a neural model obtained from an on-line neural identifier, which uses a recurrent neural network, trained with the extended Kalman filter (EKF); the last one allows the applicability of an inverse optimal neural controller. The proposed algorithm is tuned to track a desired trajectory; this trajectory reproduces the glucose absorption of a healthy person. The applicability of the proposed control scheme is illustrated via simulations.  相似文献
