Leading Firms As Knowledge Gatekeepers In A Networked Environment, Deogratias Harorimana Mr Nov 2008

Leading Firms As Knowledge Gatekeepers In A Networked Environment, Deogratias Harorimana Mr

Dr Deogratias Harorimana

This chapter introduces the role of the knowledge gatekeeper as a mechanism by which knowledge is created and transferred in a networked environment. Knowledge creation and transfer are essential for building a knowledge based economy. The chapter considers obstacles that inhibit this process and argues that leading firms create a shared socio-cultural context that enables the condivision of tacit meanings and codification of knowledge. Leading firms act as gatekeepers of knowledge through the creation of shared virtual platforms. There will be a leading firm that connects several networks of clients and suppliers may not interact directly with one another, but …

A Generic Design Environment For The Rural Industry Knowledge Acquisition (With Don Kerr And John Gammack), Shah Jahan Miah Jan 2008

A Generic Design Environment For The Rural Industry Knowledge Acquisition (With Don Kerr And John Gammack), Shah Jahan Miah

Dr Shah Jahan Miah

This paper describes a new knowledge acquisition method using a generic design environment where context-sensitive knowledge is used to build specific DSS for rural business. Although standard knowledge acquisition methods have been applied in rural business applications, uptake remains low and familiar weaknesses such as obsolescence and brittleness apply. We describe a decision support system (DSS) building environment where contextual factors relevant to the end users are directly taken into consideration. This ‘‘end user enabled design environment” (EUEDE) engages both domain experts in creating an expert knowledge base and business operators/end users (such as farmers) in using this knowledge for …

Validation Of Programmes Of Higher Education In Ireland - The Role Of The Higher Education And Training Awards Council, Deirdre Lillis, Tara Ryan Jan 2008

Validation Of Programmes Of Higher Education In Ireland - The Role Of The Higher Education And Training Awards Council, Deirdre Lillis, Tara Ryan

Deirdre Lillis

This paper considers the programme validation arrangements in place in one half of the Irish higher education sector. It outlines how responsibility for programme validation can be safely delegated to Institutions within a robust overarching framework for quality assurance. It compares programme validation in Institutions with self awarding status with Institutions that have their programmes validated by a national Awarding agency. The paper concludes that when programme validation in Ireland and (potentially) across Europe is examined more closely, processes that appear to be very different on the surface can be quite similar in reality. From a philosophical perspective it appears …

Evidence Contrary To The Statistical View Of Boosting, David Mease, A. Wyner Jan 2008

Evidence Contrary To The Statistical View Of Boosting, David Mease, A. Wyner

David Mease

The statistical perspective on boosting algorithms focuses on optimization, drawing parallels with maximum likelihood estimation for logistic regression. In this paper we present empirical evidence that raises questions about this view. Although the statistical perspective provides a theoretical framework within which it is possible to derive theorems and create new algorithms in general contexts, we show that there remain many unanswered important questions. Furthermore, we provide examples that reveal crucial flaws in the many practical suggestions and new methods that are derived from the statistical view. We perform carefully designed experiments using simple simulation models to illustrate some of these …
