Authors: Liu Xu‐Xun , Cao Yang , Chen Xiao‐Wei 
Published: May 2009

PurposeThe purpose of this paper is to search an energy balance routing in the wireless sensor networks (WSN) and lengthen the life of the networks.Design/methodology/approachTo save energy in the WSN, some routing protocols search routing with the minimum total energy consumption of the network, and others reduce data redundancy by data aggregation. But if the distribution of energy consumption was not even, the energy of some nodes would be exhausted rapidly and thus the whole network would break down. Thus, an energy balance routing notion, including communication energy cost of the routing, remaining energy of communication sensors and sensor load have been involved. Then a new algorithm, mouse colony optimization and simulated annealing (SA), is advanced to solve the problem of energy balance routing in the network.FindingsThe energy balance routing, based on mouse colony optimization and SA, performs well and yields better performance than other congener algorithms.Research limitations/implicationsThe appointed times of the algorithm is the main limitation which increase the complexity of the algorithm.Practical implicationsA very useful routing in wireless sensor networks.Originality/valueThe new approach of energy balance routing notion, including communication energy cost of the routing, remaining energy of communication sensors and sensor load. The new algorithm, mouse colony optimization algorithm, simulated mice action, was proposed to solve the energy balance routing of the network.
Short‐term forecast of the gas dissolved in power transformer using the hybrid grey model
Authors: Song Bin , Zheng‐hong Peng 
Published: May 2009

PurposeThe purpose of this paper is to define new method (grey model (GM)) for predicting the value of gases in oil‐immersed power equipment, as well as change the traditional GM which requires equal interval data.Design/methodology/approachTrend forecasting is an important aspect in fault diagnosis and work state supervision, however, in practice, it is not practical that a number of data is necessary to build the forecast model. In transformer, the concentration of the gases dissolved in transformer oil is associated with gas type, oil quality, oil temperature, transformer load, etc. which some are known, others are unknown. So it can consider that transformer is grey system and the theory of grey system is chosen as a mathematical framework to solve the problem of forecasting the change of gases.FindingsIf possible, the results should be accompanied by significance.Research limitations/implicationsAccessibility and availability of data are the main limitations which model will be applied.Practical implicationsA very useful advice for power transformer fault diagnosis method based on dissolved gas analysis data.Originality/valueThe paper presents a new approach of forecasting the value of gases in oil‐immersed power equipment and is aimed at unequal interval gases data which is used to GM.

Authors: Johannessen Jon‐Arild , Olsen Bjørn 
Published: May 2009

PurposeTurbulence and complexity in the business environment is growing along with the need for external information in creating innovation, as innovation is seen as the primary source of sustainable competitive advantages in the knowledge economy. Consequently, the underlying information processes were external information are gathered and put into use, are crucial for companies in their development of innovation, and ultimately their capacity to limit imitation and create sustainable competitive advantages.Design/methodology/approachThe research question in this paper is, how can systemic knowledge processes create innovation and promote competitive advantages? Through a conceptual model it is argued that a prerequisite for the acquisition, development, integration and application of knowledge, is the existence of systemic knowledge processes, percolation processes and networking.FindingsIt is through these processes that organizations can develop innovations, which ultimately will lead to sustainable competitive advantages.Originality/valueProvides an insight into, and an understanding of knowledge processes, innovation and sustainable competitive advantages in the business environment.
Toward a holistical perception of the content of business ethics
Authors: Potocan Vojko , Mulej Matjaz 
Published: May 2009

PurposeThe purpose of this paper is to offer a new requisitely holistic definition of business ethics (BE) as a crucial component of business cybernetics and practice. The present contribution considers a basic problem: how humans use BE to influence their business processes. Therefore, business is/should be investigated from the viewpoint of ethics. Requisite holism of understanding and consideration of BE in business reality is unavoidable; it can (and must) result from findings and considerations of the interdependence between business practice, ethics, and BE.Design/methodology/approachIn this paper, qualitative analysis is applied on the basis of the cybernetics (e.g. especially business cybernetics), dialectical systems theory, and ethics theory.FindingsEthics is a crucial emotional part of human attributes. They can be viewed as the subjective part of the starting points of any human acting/behavior process, including business. Thus, ethics (may) have/has a crucial role in business cybernetics and practice as BE. To clarify and beneficially use BE, one must understand relations between business cybernetics and BE, between business practice and BE, and understand the diversity of content of BE in literature, etc. On this base offered here is an understanding of BE, a definition of the content of BE as a specific type/part of ethics, and a view at source of BE content.Research limitations/implicationsContent of BE. Research is limited to hypothesis and qualitative analysis in desk research. Practical experience is considered implicitly.Practical implicationsThis is a step toward development of business cybernetics with a requisitely holistic approach founded on requisite wholeness of insight. A more specifically created and target‐oriented approach to cybernetic understanding and research of BE of business systems is encouraged.Originality/valueThis paper presents a very new approach, rarely found in main‐stream literature; a new perception and definition of content of BE.

Authors: Folorunso Olusegun , Akinwale Adio T. 
Published: May 2009

PurposeThe purpose of this paper is to suggest a conceptual analysis and design of knowledge management (KM) system for “Ifa” divination. In previous research, a randomized expert system for “Ifa” was proposed. In the system, the signatures of the divine‐chain are simulated through randomization process from 1 to 16, triggering the inference engine and knowledge base. This system has been experimented and it works.Design/methodology/approachThe paper proposes a conceptual analysis and design of KM system for “Ifa.” In this system, applying KM to “Ifa” oracle consultation plays the core role. Moreover, the formal explanation of the whole process is given.Findings“Ifa” knowledge visualization was designed with Visual Basic 6.0 and MS‐Access for storing “Ifa” data. The paper presents an application tagged “Ifagraph” – an oracle browser version 1.0.0 that displays the signatures when executed.Originality/valueThis is a novel approach that promotes indigenous technology from an African perspective.
Co‐operation and collaboration: the case of the de‐regulated New Zealand electricity industry
Authors: Hooks Jill , Palakshappa Nitha 
Published: May 2009

PurposeThe purpose of this paper is to use the New Zealand electricity industry as a case study to describe and understand the importance of collaborative relationships in coping with the changes faced by sectors of the industry over the last two decades.Design/methodology/approachA multi‐method qualitative approach is used to investigate the nature of industry relationships. Data were collected through two‐phase in‐depth interviews with key electricity employees. Secondary documents and archival records were used to support participant contributions.FindingsThe research finds that the majority of the collaborative relationships in the New Zealand electricity industry are “forced”. Nevertheless, and despite the preclusions of competition, relationships continue to support the strategic imperatives of firms and form an important component of firm‐level operation.Originality/valueThe study provides an understanding of collaboration within a new contextual setting – the New Zealand electricity industry. To the best of one's knowledge, no other study has attempted to assess the importance of collaboration on these industry players. The qualitative analysis undertaken made it possible to discover insights that would not have emerged from more commonly used quantitative methodologies.
Implementation, communication and benefits of public sector codes of ethics
Authors: Svensson Göran , Wood Greg 
Published: May 2009

PurposeThe purpose of this paper is to examine the implementation, communication and benefits of codes of ethics in the public sector of Sweden.Design/methodology/approachThe research is based on a longitudinal approach. It examines the ethos of codes of ethics in the largest public sector organizations of Sweden in 2001‐2002 and 2005‐2006.FindingsOnly a few of the largest public sector organizations in Sweden have indicated that they possess codes of ethics. This finding may be explained by the current judicial legislation that governs Swedish society. The public codes of ethics have been established both recently and, in part, years ago.Research limitations/implicationsA suggestion for further research would be to examine the implementation, communication and perceived benefits of public sector codes of ethics in other countries. Another area of further research would be to replicate the reported surveys in the future to examine the existence of potential trends.Practical implicationsWhen it comes to the perceived benefits of public sector codes of ethics there appears to be only minor acknowledgement of the code being used to resolve ethical problems in society. However, there is a strong conviction that the code of ethics positively influences the operations of public sector organizations.Originality/valueThe paper examines the ethical implementation, communication and benefits put in place by private companies to embed codes of ethics into their organizations.
Moving hospitals toward e‐learning adoption: an empirical investigation
Authors: Hung Shin‐Yuan , Chen Charlie C. , Lee Wan‐Ju 
Published: May 2009

PurposeMedical errors cause a significant number of deaths. Providing training to medical staff can improve the quality of medical care. Hospitals have traditionally used face‐to‐face modality to train staff but they are beginning to adopt e‐learning systems that can easily deliver training at work or to other convenient locations. The purpose of this paper is to investigate factors leading to e‐learning adoption in hospitals.Design/methodology/approachA framework of factors leading to the adoption decision of e‐learning systems is first proposed. Survey data are collected to empirically test the proposed framework. The samples consist of senior executives and managers in hospitals.FindingsIt is found that three factors including managerial, organizational, and technological exhibit significant influences on the adoption decision. One novel result is that the organizational variable of hospital specialization significantly influences the decision to adopt e‐learning systems.Research limitations/implicationsThis study is one of the first to propose a model of adoption of e‐learning specifically in the context of hospitals. Limitations and strengths of the study and possible future research direction are also discussed.Practical implicationsFrom a practitioner's standpoint, the results of this study can help hospital administrators to accelerate the adoption of e‐learning systems.Originality/valueThis study is one of the first to propose a model of adoption of e‐learning specifically in the context of hospitals. It is expected that the model developed can assist to further understand the e‐learning adoption in hospitals.
Resisting change from within and without the organization
Authors: Cutcher Leanne 
Published: May 2009

PurposeThe purpose of this paper is to contribute further to the understanding of why and how employees resist workplace change. Building on previous studies exploring the link between worker subjectivity and workplace change, the paper highlights both the spatial and temporal dimensions of tactics of resistance.Design/methodology/approachThe paper draws on case study evidence from an Australian credit union that had implemented significant changes to its service strategy, and identifies employee responses to these changes.FindingsThe case study identifies the way in which tradition and place can be discursive resources with which employees resist changes to work practices and roles which threaten to disrupt workplace and gender identities.Originality/valueTo date, the literature has focused on tactics of resistance that draw on temporal and spatial narratives from inside the organization. This paper extends the understanding by showing how individuals also draw on narratives from outside the organization to resist workplace change.
Organizational slack: is more or less better?
Authors: Chiu Yi‐Chia , Liaw Yi‐Ching 
Published: May 2009

PurposeThe purpose of this paper is to attempt to reconcile previous views of the relationship between organizational slack and performance by examining the influences of heterogeneous corporate strategy and different slack resources. Differences in performance resulting from variations in slack can also be moderated by strategy.Design/methodology/approachThe proposed model was tested by examining operating and financial information from 529 Taiwan high‐tech companies during the period 1997‐2005. Owing to the study, data were both cross‐sectional (across firms) and time series (over years), a panel data approach were applied for hypothesis testing.FindingsThe results broadly demonstrate that relationships differ based on strategy and organizational slack. Additionally, this study is the first to empirically identify a U‐shaped relationship between slack and performance, indicating that, in certain circumstances, either more or less slack is better for performance.Originality/valueThe results support a dynamic perspective regarding the slack‐performance relationship was proposed for different strategy and different types of slack resources. Moreover, the authors argue that not only resource heterogeneity, but also firm strategic orientation, should be considered when performing change activities. Restated, the authors believe the best interest for a firm aspiring to conduct organizational change behaviors is to maintain the “fitness” among the environment, strategy orientation, and slack resources will induce higher performance. This study, thus demonstrates how organizational change behaviors are influenced by slack resources and strategy heterogeneity.
Recycled wool‐based nonwoven material for decolorisation of dyehouse effluents
Authors: Radetic Maja , Radojevic Darinka , Ilic Vesna , Mihailovic Darka , Jovancic Petar 
Published: May 2009

PurposeThe purpose of this paper is to investigate the possible application of recycled wool‐based nonwoven material (RWNM) for removal of different dyes that are used in textile dye houses.Design/methodology/approachThe sorption kinetics, the influence of initial dye concentration, pH and temperature are analyzed. Basic, reactive, direct and metal complex dyes are studied.FindingsThe sorption properties are highly influenced by the type of the dye owing to differences in their chemical structure and thus, the mechanism of binding to wool. Modification of material with chitosan and hydrogen peroxide improves the sorption capacities and sorption rates but no general trend can be established. Consequently, the sorption behaviour is analyzed separately for each type of the dye.Originality/valueThe results indicate that RWNM can be used as an efficient, low‐cost sorbent for decolorisation of effluents.

Authors: Kilic Bengi , Cireli Aksit Aysun , Mutlu Mehmet 
Published: May 2009

PurposePlasma polymerization is a very promising technique to produce functional textile materials for any textile end uses as well as for high performance clothing. It can be possible to obtain highly cross‐linked, pinhole free and very thin polymer films up to 1 μm thickness with unique physical and chemical properties. These films can be used as very effective barriers. The purpose of this paper is to investigate the influences of plasma polymerization of hexamethyldisilane (HMDS) and hexamethyldisiloxane (HMDSO) on the surface properties of cotton and polyamide fabrics.Design/methodology/approachThe methodology is based on the surface modification of the cotton and polyamide fabrics by plasma polymerization of HMDS and HMDSO. The fabrics are modified by low pressure low temperature RF (radio frequency −13.56 MHz) plasma polymerization system under different power and time conditions. The changes in surface structure and morphology of the fabrics are investigated by Fourier transform infrared spectroscopy‐attenuated total reflectance (FTIR‐ATR) analysis and atomic force microscopy (AFM).FindingsWater repellency of polyamide fabrics is strongly enhanced after plasma polymerization of both HMDS and HMDSO monomers. In addition to this, the treatments are found to slow down the vertical flame spread in cotton fabrics.Originality/valueIncreased water repellency and decreased vertical flame spread are achieved using plasma polymerization technique in a very short time with very little amount of chemical and without water and auxiliary agent.
