Reducing semantic complexity in distributed digital libraries
Authors: Mayr Philipp , Mutschke Peter , Petras Vivien 
Published: May 2008

PurposeThe general science portal “vascoda” merges structured, high‐quality information collections from more than 40 providers on the basis of search engine technology (FAST) and a concept which treats semantic heterogeneity between different controlled vocabularies. First experiences with the portal show some weaknesses of this approach which come out in most metadata‐driven Digital Libraries (DLs) or subject specific portals. The purpose of the paper is to propose models to reduce the semantic complexity in heterogeneous DLs. The aim is to introduce value‐added services (treatment of term vagueness and document re‐ranking) that gain a certain quality in DLs if they are combined with heterogeneity components established in the project “Competence Center Modeling and Treatment of Semantic Heterogeneity”.Design/methodology/approachTwo methods, which are derived from scientometrics and network analysis, will be implemented with the objective to re‐rank result sets by the following structural properties: the ranking of the results by core journals (so‐called Bradfordizing) and ranking by centrality of authors in co‐authorship networks.FindingsThe methods, which will be implemented, focus on the query and on the result side of a search and are designed to positively influence each other. Conceptually, they will improve the search quality and guarantee that the most relevant documents in result sets will be ranked higher.Originality/valueThe central impact of the paper focuses on the integration of three structural value‐adding methods, which aim at reducing the semantic complexity represented in distributed DLs at several stages in the information retrieval process: query construction, search and ranking and re‐ranking.
The information‐seeking problems of English high schoolers responding to academic information need
Authors: Shenton Andrew K. 
Published: May 2008

PurposeThe problems experienced by young people when looking for information are significantly under‐researched and this paper aims to attempt to expand the fragmented knowledge base. It concentrates on action taken by English high schoolers to meet academic information needs.Design/methodology/approachThe work draws on qualitative data elicited via an online questionnaire administered in October and November 2006. Thirty‐five participants contributed data on the problems they had encountered.FindingsInductive coding of the data revealed that over 20 individual problems were apparent. The most frequently mentioned was an inability to locate the desired information. Some of the other issues related to information use, rather than information‐seeking.Research limitations/implicationsThe project was small scale, with data collected from pupils in only one school. It relied solely on self‐reported data and insight into information‐seeking problems was gained purely in terms of behaviour to satisfy academic information needs. A future project may consider issues that develop when youngsters are intent on meeting leisure‐oriented needs.Practical implicationsThe findings have implications for the improvement of Web filters and the teaching of information skills, especially with respect to the effective use of search engines and the training of learners in information‐seeking methods beyond the use of the Internet.Originality/valueThe paper is unusual in exploring information‐seeking problems entirely from the perspective of information users. It is envisaged that the research will be of use to academics interested in information behaviour, teachers in secondary schools and information professionals who work with young people.
Friction coefficient and surface roughness of TiN‐coated HSS deposited using cathodic arc evaporation PVD technique
Authors: Ali Mubarak , Hamzah Esah , Radzi Toff Mohammad 
Published: May 2008

PurposeThe purpose of this paper is to examine the effect of substrate temperature on friction coefficient and surface roughness of titanium nitride (TiN) coatings deposited on high‐speed steel (HSS) using commercially available cathodic arc evaporation physical vapour deposition system.Design/methodology/approachThe goal of this work is to determine the usefulness of TiN coatings in order to improve the friction coefficient and surface roughness of HSS verses substrate temperature, as vastly used in cutting tool industry and many others. A Pin‐on‐Disc test was carried out to study the coefficient of friction verses sliding distance. Surface roughness of deposited coatings was studied via surface roughness tester and atomic force microscope (AFM).FindingsFriction coefficient increased at higher temperature as compared to the coating deposited at lower substrate temperature. Surface roughness measured via both instruments showed similar trend in recorded data and, i.e. increased by increasing substrate temperature. AFM study showed that bearing ratio (per cent) decreased, whereas, fractal dimension increased with an increase in substrate temperature.Research limitations/implicationsIt is implied that choosing a substrate temperature above 450°C in the existing coating system could damage some machine parts.Practical implicationsThis scenario develops an approach to optimize the coating properties verses substrate temperature for specific application, such as cutting tools for automobiles and aircrafts.Originality/valueThe coating deposited at lower temperature showed better friction coefficient and surface roughness than the coating deposited at higher temperature and vice versa.
Entrepreneurship education: towards an industry sector approach
Authors: Richardson Ita , Hynes Briga 
Published: May 2008

PurposeThe purpose of this paper is to consider the requirements for an industry sector approach to entrepreneurship education – the information and communications technology (ICT) sector. A modified Process Framework for Entrepreneurship Education is presented focusing specifically on ICT. The primary components of the Process Framework are described (inputs, process and content, assessment and outputs) to assist in the design of relevant and targeted entrepreneurship education courses to create an entrepreneurial mindset for graduates in this sector. This Framework can be modified to suit courses focusing on other industry sectors.Design/methodology/approachBased on experiential learning and industry sector knowledge, an existing Process Framework for Entrepreneurship Education is modified.FindingsThe Process Framework for Entrepreneurship Education can be modified for a specific sector. Inputs to the process include the personal profiles and personality characteristics of the students. The recognition that particular skills may be required within a sector should be catered for when developing the content focus of the process. Furthermore, the teaching focus should include action learning, problem based learning and discovery teaching. Consideration of all of these elements will help ensure that the entrepreneurship teaching process will develop entrepreneurial‐focused students within the sector. Entrepreneurship education is a flexible learning mode easily modified to accommodate changing workplace and employee needs. The use of the process framework provides for a set of useful and relevant guidelines on the key aspects which should be addressed and used as a checklist in attempting to modify and design suitable and relevant entrepreneurship education programmes for specific industry sectors.Originality/valueThis paper demonstrates that educators need to consider entrepreneurship for industry sectors, thus presenting the requirement for an inter‐disciplinary approach to entrepreneurship. It does so through the refinement of an existing Process Framework for Entrepreneurship Education, taking the specific example of Information and Communications Technology. While the framework can be modified for use in other sectors, this paper presents the integration of and highlights the synergy that exists in the linking of entrepreneurship with the technical disciplines.

Retention and intentions to quit among Australian male apprentices
Authors: Gow Kathryn , Warren Chantelle , Anthony David , Hinschen Connie 
Published: May 2008

PurposeIn response to both the increasing concern of the declining rates of apprentices and the limited research in this area, the purpose of this paper is to investigate the individual processes involved in apprentices' decisions to remain in their apprenticeship.Design/methodology/approachSpecifically, five individual domains were investigated: motivation style (intrinsic and extrinsic motivation); coping style (emotion‐focused and problem‐focused); apprentice experiences (satisfaction, work conditions, expectations, formal training and recognition); financial responsibility; and demographic factors (age, geographic location, education/training and organisational tenure). Three measures were used to assess these five domains: the work preference inventory, the brief cope and the apprentice experience questionnaire. A total of 326 male participants were recruited from Victoria and Queensland.FindingsLogistic regression was performed to determine if motivation style, coping style, apprentice experiences and demographic factors could predict thoughts towards remaining in an apprenticeship. A Chi‐square test was conducted to determine if financial responsibility had an impact on thoughts towards remaining in a trade. Overall results suggested that intrinsic motivation, satisfaction, working conditions and geographic location could predict apprentices' thoughts towards staying in an apprenticeship.Research limitations/implicationsThe results can only be generalised to those who were currently undertaking an apprenticeship and not those who had already left. Furthermore, the outcome variable in this study was “thoughts towards quitting” and not actual quitting per se; however, social desirability effects may have influenced the responses somewhat.Originality/valueBy utilising this data, educators and employers alike could now be one step closer to retaining the much‐needed apprentices of Australia and it may be that other countries such as Germany, India, France, Turkey, the USA, and the UK may pool informational research resources to counter the global downturn in apprentices' availability.

Published: May 2008

PurposeThe project Climbing Robot Cell for Fast and Flexible Manufacture of Large Scale Structures seeks to modernise and take into the future the technology of the manufacture of large fixed welded structures. It creates a transportable manufacturing cell consisting of a team of cooperating climbing robot work tools whose activities are coordinated and integrated through a central intelligence. The purpose of this paper is to present a wheeled robot, called NDT robot, designed for the real time inspection of long weld lines simultaneously with the welding process.Design/methodology/approachNeodymium permanent magnets are used for adhesion, which are capable of producing a maximum adhesion pressure of 4 × 104 Nm−2at a 20 mm air gap. The strong neodymium magnets give the robot a high payload carrying capability. The arrangement of the magnet array increases its performance at large air gaps so that the robot has excellent capability to overcome obstacles, such as weld caps. The design of the wheeled robot with two sections jointed by a hinge joint has the advantage of high speed and good manoeuvrability, as well as working on curved surfaces and transferring between angled adjoining surfaces.FindingsThe NDT robot has been developed with the capability of climbing on steel walls carrying the specified payload and the ability to overcome the obstacles. The robot is also able to climb on curved surfaces with excellent manoeuvrability, and transfer between angled adjoining surfaces.Originality/valueThe arrangement of the magnet array enables the robot to retain a strong holding force at big air gap, so that the ability of the robot to overcome obstacles and work on curvatures is strengthened. The two‐section design improves the robot's performance on curvatures and enables it to transfer between angled adjoining surfaces.

Adaptive neuro‐fuzzy current control for multilevel inverter fed induction motor
Authors: Tuncer Servet , Dandil Beşir 
Published: May 2008

PurposeThe paper aims to propose an adaptive and robust on‐line trained neuro‐fuzzy current controller based on indirect field oriented control (IFOC) for the current control of multilevel inverter fed induction motor (IM).Design/methodology/approachTorque current of IM is controlled with Sugeno type neuro‐fuzzy controller (NFC) which has the ability of self tuning against parameter variations and load disturbance. Input variables of the neuro‐fuzzy current controller are chosen error and integral of error in order to eliminate steady state error. The consequent parameters of neuro‐fuzzy current controller are trained on‐line through backpropagation learning algorithm.FindingsThe validity of proposed current control algorithm is shown with experimental results carried out under different speed commands, parameter variations and load disturbances. The experimental results show that control performance of NFC in the current control of IMs is satisfactory because of its adaptive and robust structure.Originality/valueThis paper presents the design of an on‐line trained neuro‐fuzzy current control to improve the current control performance. The performance of the current controller largely depends on using converter systems. In this study, a multilevel inverter is used to obtain less harmonic distortion and near sinusoidal form of output voltage and current waveforms of the converter.

Pore network modelling using image processing techniques
Authors: Dimassi M. , Koehl L. , Zeng X. , Peruwelz A. 
Published: May 2008

PurposeThe knowledge of structural parameters of nonwovens media is poorly understood. The pores size distribution (PSD) function is one of those parameters. The difficulty is not only the understanding of the distribution of pores but also the identification of pores geometry distribution (PGD) and their behaviour concerning the dynamic fluid transportation. The purpose of this paper is to present an efficient and reliable method based on image analysis which on one hand, performs the estimation of the PSD function and takes into account the geometric aspect of pores, and on the other hand, analyses liquid wicking in very thin filter media.Design/methodology/approachThe proposed methods, in this paper, are applied on thin filter media made of polyester. The samples have not sudden any treatment. The authors set up an optical test bed in order to observe the dynamic properties of the samples. Dynamic raw data about the liquid wicking are extracted directly from video sequences using the appropriate test bed. The structural parameters are extracted from the non‐wetted samples.FindingsObtained results allow a better understanding of the liquid wicking in very thin filter media. In addition to the PSD function, the PGD function adds informations about the shape of pores. The dynamic data of the liquid wicking explains that pores have different behaviour when liquid reached them. It can be deduced from this study that the fluid transport in the pore network is defined by three main parameters: geometric parameter (size, shape), capillary action and pores connection in the network.Research limitations/implicationsThe led back‐lighting system is not sufficient to observe precisely the liquid wicking. An additional front‐lighting will be added in further studies.Originality/valueThe extraction of dynamic properties from video sequences, by performing image analysis is an original method to characterise the porosity in thin media filter.
Marketing destination Niagara effectively through the tourism life cycle
Authors: Brooker Edward , Burgess Jason 
Published: May 2008

PurposeThe purpose of this paper is to address reasons why destinations stagnate and lose visitor numbers and to offer a series of methods, which stakeholders can employ to assist with rejuvenation efforts.Design/methodology/approachThe paper is based on a limited literature review of Butler's Tourism Area Life Cycle (1980). The academic theory is applied to the on‐going situation that is occurring in the Niagara region of Canada, although the insights are applicable to other tourism destinations that are facing stagnation and decline.FindingsWhile Niagara tourism is currently experiencing a decline in visitor numbers brought about by a series of factors, the destination has the opportunity to rejuvenate its offering. Key components of the rejuvenation include collaboration, strategizing, developing a destination brand that resonates with existing and future visitors and incremental and revolutionary innovation. Once these key elements are in play, the destination should see visitor numbers rebound if not surpass previous high water marks.Originality/valueThis paper is of value to destination marketing officials and entrepreneurs who may believe visitation numbers are lower as a result of a variety of external factors including rising fuel prices, global warming, terrorism threats, changing passport regulations, SARS, hurricanes, tsunamis, and other concerns. By understanding the signals associated with stagnation, destination stakeholders will be in a position to take proactive actions designed to rejuvenate the destination.
Strategic planning in emergent market organizations: empirical investigation
Authors: Al‐Shammari Hussam A. , Hussein Raef T. 
Published: May 2008

PurposeThis study is designed to examine strategic planning practices in Jordanian manufacturing organizations (JMOs). Two issues are of primary concern here. The first is related to the extent of using strategic planning in JMOs, while the second issue is concerned with the infrastructure necessary to implement successful strategic planning.Design/methodology/approachData were collected via a questionnaire that was administered to the CEOs of the 37 manufacturing firms included in this study. Out of the 37 questionnaires distributed, 28 were returned representing a response rate of 76 percent.FindingsResults reveal that 39 percent of JMOs are implementing strategic planning, whereas 61 percent are not. Results also indicate that while JMOs managers possess strong and positive attitudes toward strategic planning; these attitudes have not been translated into real commitment. A low to moderate level of commitment, low level of participation, and moderate strength of information system are found in this study.Originality/valueSo far, only limited empirical research has been conducted to explore strategic planning practices in Jordanian business organizations (JBOs). Our current study is among the few pioneering studies that have contributed to the enhancement of our understanding of strategic planning practices in JBOs.
