Information technology for knowledge management in Malaysia: The effects of organisational factors
This study attempts to identify organisational
factors that could influence the adoption of IT to support KM in a Malaysian setting. In addition to the two major constructs of the technology acceptance model (TAM), a research model was developed by incorporating six variables of organisational factors. Analysis of data collected from a survey of 830 Malaysian listed organisations showed that all variables of organisational factors have significant contribution to the adoption of IT for KM, except management support and commitment, and reward and incentive.
This research outlines some management
implications and extends the applicability of TAM in Malaysian KM context
Knowledge Nodes: the reification of organizational communities. A case study
In our work a new approach, the Distributed Knowledge Management (DKM) approach, is used and organizations are seen as constellations of communities, which \own" local knowledge and exchange it through meaning negotiation coordination processes. In order to reify communities within a DKM system, the concept of Knowledge Node (KN) is used and then applied in a case study: a complex Italian national firm, the Impresa Pizzarotti & C. S.p.A. All communities of practices are un-veiled and rei ed as KNs within a high level architecture of a DKM system. In this paper it is argued that, even if knowledge has to be organized and made useful to the whole organization, there are types of knowledge that must be managed in an autonomous way, and the DKM approach is a good system which to deal with coordination/negotiation processes
A literature review of knowledge management, facilities management and link between those two disciplines
This paper tries to scrutinize the nature of knowledge management and facilities management within their variety of definitions, through a literature review. It concentrates on identifying
different broad views and definitions of each subject area. At the same time the paper concentrates on ascertaining the core features of each discipline during the literature review. By evaluating these core features of each discipline, the paper then discusses the importance of managing the knowledge within the facilities management domain. Finally, by evaluating potential interrelationships between knowledge
management and facilities management, it describes how and where the concepts of knowledge
management can be used to manage facilities for organisational success, followed by a discussion about how and where facilities management concepts can effectively be used for successful implementation of knowledge management exercises
Study on thermal model for calculating transformer hot Spot temperature
A power transformer is a static piece of apparatus with two or more windings which, by
electromagnetic induction, transforms a system of alternating voltage and current into another
system of voltage and current usually of different values and at same frequency for the purpose
of transmitting electrical power.
The hot spot temperature depends on instantaneous load and ambient temperature,
winding design and also cooling model. There are two possible methods for hotspot temperature
determination. The first method is to measure the hot spot temperature using a fiber optic, and
other is to calculation the hotspot temperature using transformer thermal models. It was noticed
that the hot spot temperature rise over top oil temperature due to load changes is a function
depending on time as well as the transformer loading (overshoot time dependent function). It has
also been noticed that the top oil temperature time constant is shorter than the time constant
suggested by the present IEC loading guide, especially in cases where the oil is guided through
the windings in a zigzag pattern for the ONAN and ONAF cooling modes. This results in winding
hottest spot temperatures higher than those predicted by the loading guides during transient states
after the load current increases, before the corresponding steady states have been reached.
This thesis presents more accurate temperature calculation methods taking into account
the findings mentioned above. The models are based on heat transfer theory, application of the
lumped capacitance method, the thermal-electrical analogy and definition of nonlinear thermal
resistances at different locations within a power transformer. The methods presented in this
thesis take into account all oil physical parameters change and loss variation with temperature.
In addition, the proposed equations are used to estimate the equivalent thermal capacitances of
the transformer oil for different transformer designs and winding-oil circulations. The models are
validated using experimental results, which have been obtained from the normal heat run test
performed by the transformer manufacturer at varying load current on a 250-MVA-ONAFcooled
unit, a 400-MVA-ONAF-cooled
unit and a 2500-KVA-ONAN-cooled
unit. The results
are also compared with the IEC 60076-7:2005 loading guide method.

Investigating knowledge management factors affecting Chinese ICT firms performance: An integrated KM framework
This is an Author's Accepted Manuscript of an article published in the Journal of Information Systems Management, 28(1), 19 - 29, 2011, copyright Taylor & Francis, available online at: http://www.tandfonline.com/10.1080/10580530.2011.536107.This article sets out to investigate the critical factors of Knowledge Management (KM) which are considered to have an impact on the performance of Chinese information and communication technology (ICT) firms. This study confirms that the cultural environment of an enterprise is central to its success in the context of China. It shows that a collaborated, trusted, and learning environment within ICT firms will have a positive impact on their KM performance
Specification of vertical semantic consistency rules of UML class diagram refinement using logical approach
Unified Modelling Language (UML) is the most popular modelling language use for
software design in software development industries with a class diagram being the
most frequently use diagram. Despite the popularity of UML, it is being affected by
inconsistency problems of its diagrams at the same or different abstraction levels.
Inconsistency in UML is mostly caused by existence of various views on the same
system and sometimes leads to potentially conflicting system specifications. In
general, syntactic consistency can be automatically checked and therefore is
supported by current UML Computer-aided Software Engineering (CASE) tools.
Semantic consistency problems, unlike syntactic consistency problems, there exists
no specific method for specifying semantic consistency rules and constraints.
Therefore, this research has specified twenty-four abstraction rules of class‟s relation
semantic among any three related classes of a refined class diagram to semantically
equivalent relations of two of the classes using a logical approach. This research has
also formalized three vertical semantic consistency rules of a class diagram
refinement identified by previous researchers using a logical approach and a set of
formalized abstraction rules. The results were successfully evaluated using hotel
management system and passenger list system case studies and were found to be
reliable and efficient
Preparing for GDPR:helping EU SMEs to manage data breaches
Over the last decade, the number of small and medium (SME) businesses suffering data breaches has risen at an alarming rate. Knowing how to respond to inevitable data breaches is critically important. A number of guidelines exist to advise organisations on the steps necessary to ensure an effective incident response. These guidelines tend to be unsuitable for SMEs, who generally have limited resources to expend on security and incident responses. Qualitative interviews were conducted with SMEs to probe current data breach response practice and to gather best-practice advice from SMEs themselves. The interviews revealed no widespread de facto approach, with a variety of practices being reported. A number of prevalent unhelpful-practice themes emerged from the responses, which we propose specific mitigation techniques to address. We therefore propose a SME-specific incident response framework that is simple yet powerful enough to inform and guide SME responses to data breach incidents
