Arabidopsis VASCULAR-RELATED NAC-DOMAIN6 Directly Regulates the Genes That Govern Programmed Cell Death and Secondary Wall Formation during Xylem Differentiation
Authors: Ohashi-Ito Kyoko , Oda Yoshihisa , Fukuda Hiroo 
Published: October 2010

Abstract
Xylem consists of three types of cells: tracheary elements (TEs), parenchyma cells, and fiber cells. TE differentiation includes two essential processes, programmed cell death (PCD) and secondary cell wall formation. These two processes are tightly coupled. However, little is known about the molecular mechanisms underlying these processes. Here, we show that VASCULAR-RELATED NAC-DOMAIN6 (VND6), a master regulator of TEs, regulates some of the downstream genes involved in these processes in a coordinated manner. We first identified genes that are expressed downstream of VND6 but not downstream of SECONDARY WALL-ASSOCIATED NAC DOMAIN PROTEIN1 (SND1), a master regulator of xylem fiber cells, using transformed suspension culture cells in microarray experiments. We found that VND6 and SND1 governed distinct aspects of xylem formation, whereas they regulated a number of genes in common, specifically those related to secondary cell wall formation. Genes involved in TE-specific PCD were upregulated only by VND6. Moreover, we revealed that VND6 directly regulated genes that harbor a TE-specific cis-element, TERE, in their promoters. Thus, we found that VND6 is a direct regulator of genes related to PCD as well as to secondary wall formation.

Authors: Chunrong Luo , Jingfen Wang , Zhinong Zhou 
Published: October 2010

PurposeThe purpose of this paper is to analyse the current situation and the social and economic benefits from the consortia acquisitions of electronic resources by the China Academic Library and Information System (CALIS) South China Regional Centre and to recommend improvements for consortia acquisitions.Design/methodology/approachAnalyses of price and usage made within the CALIS South China region of databases from a range of suppliers including EBSCO, LexisNexis and Springer are presented.FindingsThe electronic resource acquisitions by the CALIS South China Regional Centre have yielded remarkable social and economic benefits as the range of electronic collections has been expanded and enriched, benefits have accrued, money has been saved and it has proved to be of benefit to users; however, there is room for improvement. During the last three years, the total usage of the South China Consortia has increased but the usage of the member libraries in the consortia is unbalanced and there are big gaps among the member libraries. The single download/search cost of the e‐resources has been gradually decreasing but the cost of the e‐resources purchased by the South China region consortia is higher than that of the national consortia; hence, there is a need for further reductions.Originality/valueThe study is the first of its kind ever conducted in China. The findings of this paper will be helpful in improving electronic resource consortia acquisitions in the South China region.
An evaluation of implementing Koha in a Chinese language environment
Authors: Chang Naicheng , Tsai Yuchin , Hopkinson Alan 
Published: October 2010

PurposeThe purpose of this paper is to evaluate issues of different scripts in the same record (in MARC21 and Chinese machine‐readable cataloguing (CMARC)) and Chinese internal codes (i.e. double‐byte character set) when implementing Koha. It also discusses successful efforts in promoting the adoption of Koha in Taiwan, particularly the contributions from Koha‐Taiwan.Design/methodology/approachA Koha CMARC/MARC21 testbed was set up to discuss issues of multi‐scripts and Chinese internal codes when implementing Koha, and to determine to what extent the various features of CMARC, which are not present in MARC21, such as linking fields, can be supported in Koha and what is required to implement them if they are not available.FindingsIn contrast to western characters, Chinese internal codes cause extra work, as special programming for character conversion is required when working with Koha. This situation is commonly seen in Asian countries such as China, Japan and Korea. This paper recommends implementing CMARC, MARC21 or even any other type of MARC format in Koha with strong commercial‐level support.Practical implicationsKoha‐Taiwan serves Koha Chinese users around the world. A successful Koha‐Taiwan could be a model around the world.Originality/valueIn recent years, the concept of implementing an open‐source library management system has been coming to the fore. In Taiwan, the local‐based commercial library system covers more than one quarter of the library system market in academic libraries because the company provides better tailor‐made support, mainly in scripts and multiple internal codes, than do western‐based commercial library systems. Evaluations and conclusions from this paper will be useful to countries where multi‐scripts and double‐byte character sets are issues.

Published: October 2010

PurposeThe purpose of this paper is to review the current status of collaboration in cultural heritage preservation in East Asia, including digital projects, and to suggest practical improvements based on a cultural structuralism perspective.Design/methodology/approachThrough exploratory research, the paper addresses aspects for successful collaboration in cultural heritage digitisation in East Asia.FindingsThe paper indicates the difference in collaboration of cultural heritage digitisation between regions such as Europe and the unique situation in East Asia.Social implicationsIf collaboration between the countries of East Asia was implemented then such a community could deal with the issues of cultural heritage by having a standard scheme or policy.Originality/valueThere has been little literature published on East Asian cultural heritage initiatives, particularly in the area of digitisation and digital preservation.
Creating complex repository collections, such as journals, with Manakin
Authors: Koenig Jack (Jay) , Mikeal Adam 
Published: October 2010

PurposeThe purpose of this paper is to report on a devised method of collection organisation within a DSpace repository using a Manakin theme and descriptive metadata.Design/methodology/approachUsing a Manakin theme, a user interface for a repository collection containing the contents of a serial was created to divide the collection into individual issues and serve the user a table of contents.FindingsThe Manakin theme delivered the desired result of a browse interface that allowed the user to select and view subsets of items within a collection.Practical implicationsFor complex collections that might require subdivisions, DSpace's rigid data model of communities and collections is not ideal. This new interface allows for the inclusion and proper display of such complex collections.Originality/valueThe paper should resonate with repository managers frustrated with the inflexibility of the default organisational structure of DSpace and its unsuitability for many different types of collections.

Authors: Díaz‐Fernández M.E. , González‐Nicieza C. , Álvarez‐Fernández M.I. , Álvarez‐Vigil A.E. , Argüelles Amado A. 
Published: October 2010

PurposeThis paper aims to present a computational approach which – setting off from measures obtained by using an overdrilling method – determines, automatically and accurately, stress changes undergone in terrain as a consequence of human activity.Design/methodology/approachThe method presented uses the data from three boreholes and the elasticity theory to represent a numerical system whose resolution allows determining the stress state in a particular point. Since the system obtained is over‐dimensioned, the Levenberg‐Marquardt minimization method has been used in order to minimize errors. This paper details the analysis carried out in order to develop the computational method.FindingsThis paper provides the algorithm for determining inner stresses in a particular point of a rock mass. Besides, a method to verify obtained results is presented, including its computational encoding in C#. Furthermore, the developed methods have been integrated in a computer tool which presents the results in a graphic environment.Research limitations/implicationsThe algorithms presented are applicable when using an overdrilling method to measure stresses.Practical implicationsA reliable determination of global stress state demands the use of any method that is numerically difficult to use. Thus, in practice, it is of great importance to dispose of some reliable automatic tool to calculate stress state.Originality/valueAccuracy in the results obtained with the tool, together with the simplicity of its interface, involves a certain advantage regarding the use of a general‐scope commercial tool, since it allows – without being necessary to be an expert user – quickly obtaining results within the analysed working area.
Detecting the sensitivity of structural damage based on the Hilbert‐Huang transform approach
Authors: Chiang Wei‐Ling , Chiou Dung‐Jiang , Chen Cheng‐Wu , Tang Jhy‐Pyng , Hsu Wen‐Ko , Liu Te‐Yu 
Published: October 2010

PurposeThis study aims to investigate the relationship between structural damage and sensitivity indices using the Hilbert‐Huang transform (HHT) method.Design/methodology/approachThe relationship between structural damage and the sensitivity indices is obtained by using the HHT method. Three sensitivity indices are proposed: the ratio of rotation (RR), the ratio of shifting value (SV) and the ratio of bandwidth (RB). The nonlinear single degree of freedom and multiple degree of freedom models with various predominant frequencies are constructed using the SAP2000 program. Adjusted PGA El Centro and Chi‐Chi (TCU068) earthquake data are used as the excitations. Next, the sensitivity indices obtained using the HHT and the fast Fourier transform (FFT) methods are evaluated separately based on the acceleration responses of the roof structures to earthquakes.FindingsSimulation results indicate that, when RR < 1, the structural response is in the elastic region, and neither the RB nor SV in the HHT and FFT spectra change. When the structural response is nonlinear, i.e. RR1, a positive trend of change occurs in RB and RR, while in the HHT spectra, SV increases with an increasing RR. Moreover, the FFT spectra reveal that SV changes only when the RR is sufficiently large. No steady relationship between the RB and the RR can be found.Originality/valueThe paper demonstrates the effectiveness of the HHT method.
Neurocomputing strategies for solving reliability‐robust design optimization problems
Authors: Lagaros Nikos D. , Plevris Vagelis , Papadrakakis Manolis 
Published: October 2010

PurposeThis paper, by taking randomness and uncertainty of structural systems into account aims to implement a combined reliability‐based robust design optimization (RRDO) formulation. The random variables to be considered include the cross section dimensions, modulus of elasticity, yield stress, and applied loading. The RRDO problem is to be formulated as a multi‐objective optimization problem where the construction cost and the standard deviation of the structural response are the objectives to be minimized.Design/methodology/approachThe solution of the optimization problem is performed with the non‐dominant cascade evolutionary algorithm with the weighted Tchebycheff metric, while the probabilistic analysis required is carried out with the Monte Carlo simulation method. Despite the computational advances, the solution of a RRDO problem for real‐world structures is extremely computationally demanding and for this reason neurocomputing estimations are implemented.FindingsThe obtained estimates with the neural network predictions are shown to be very satisfactory in terms of accuracy for performing this type of computation. Furthermore, the present numerical results manage to achieve a reduction in computational time up to four orders of magnitude, for low probabilities of violation, compared to the conventional procedure making thus feasible the reliability‐robust design optimization of realistic structures under probabilistic constraints.Originality/valueThe novel parts of the present work include the implementation of neurocomputing strategies in RRDO problems for reducing the computational cost and the comparison of the results given by RRDO and robust design optimization formulations, where the significance of taking into account probabilistic constraints is emphasized.
Stochastic sensitivity analysis using preconditioning approach
Authors: Chowdhury R. , Adhikari S. 
Published: October 2010

PurposeHigh‐dimensional model representation (HDMR) is a general set of quantitative model assessment and analysis tools for capturing the high‐dimensional relationships between sets of input and output model variables. It is an efficient formulation of the system response, if higher‐order cooperative effects are weak, allowing the physical model to be captured by the lower‐order terms. The paper's aim is to develop a new computational tool for estimating probabilistic sensitivity of structural/mechanical systems subject to random loads, material properties and geometry.Design/methodology/approachWhen first‐order HDMR approximation of the original high‐dimensional limit state is not adequate to provide the desired accuracy to the sensitivity analysis, this paper presents an enhanced HDMR (eHDMR) method to represent the higher‐order terms of HDMR expansion by expressions similar to the lower‐order ones with monomial multipliers. The accuracy of the HDMR expansion can be significantly improved using preconditioning with a minimal number of additional input‐output samples without directly invoking the determination of second‐ and higher‐order terms. As a part of this effort, the efficacy of HDMR, which is recently applied to uncertainty analysis, is also demonstrated. The method is based on computing eHDMR approximation of system responses and score functions associated with probability distribution of a random input. Surrogate model is constructed using moving least squares interpolation formula. Once the surrogate model form is defined, both the probabilistic response and its sensitivities can be estimated from a single probabilistic analysis, without requiring the gradients of performance functions.FindingsThe results of two numerical examples involving mathematical function and structural/solid‐mechanics problems indicate that the sensitivities obtained using eHDMR approximation provide significant accuracy when compared with the conventional Monte Carlo method, while requiring fewer original model simulations.Originality/valueThis is the first time where application of eHDMR concepts is explored in the stochastic sensitivity analysis. The present computational approach is valuable to the practical modelling and design community.
A new approach for prediction of the stability of soil and rock slopes
Authors: Ahangar‐Asr Alireza , Faramarzi Asaad , Javadi Akbar A. 
Published: October 2010

PurposeAnalysis of stability of slopes has been the subject of many research works in the past decades. Prediction of stability of slopes is of great importance in many civil engineering structures including earth dams, retaining walls and trenches. There are several parameters that contribute to the stability of slopes. This paper aims to present a new approach, based on evolutionary polynomial regression (EPR), for analysis of stability of soil and rock slopes.Design/methodology/approachEPR is a data‐driven method based on evolutionary computing, aimed to search for polynomial structures representing a system. In this technique, a combination of the genetic algorithm and the least square method is used to find feasible structures and the appropriate constants for those structures.FindingsEPR models are developed and validated using results from sets of field data on the stability status of soil and rock slopes. The developed models are used to predict the factor of safety of slopes against failure for conditions not used in the model building process. The results show that the proposed approach is very effective and robust in modelling the behaviour of slopes and provides a unified approach to analysis of slope stability problems. It is also shown that the models can predict various aspects of behaviour of slopes correctly.Originality/valueIn this paper a new evolutionary data mining approach is presented for the analysis of stability of soil and rock slopes. The new approach overcomes the shortcomings of the traditional and artificial neural network‐based methods presented in the literature for the analysis of slopes. EPR provides a viable tool to find a structured representation of the system, which allows the user to gain additional information on how the system performs.
Corporate social responsibility activity reportage on bank websites in Ghana
Authors: Hinson Robert , Boateng Richard , Madichie Nnamdi 
Published: October 2010

PurposeThe concept of corporate social responsibility (CSR) has witnessed a resurgence in the management literature in recent years. This might be due to a renewed focus on corporate governance and ethical practices of companies the world over. This current study seeks to focus on how banks operating in Ghana communicate their CSR programmes and intentions via their corporate websites.Design/methodology/approachA conceptual framework was adapted from the extant literature and was used as the basis of a content analysis of 16 banks in Ghana. This paper adopts a qualitative research approach drawing upon available information from the websites of these 16 banks.FindingsOne of the banks that had won the most CSR awards at the Ghana banking awards had the poorest CSR communication content on its corporate website. It was also noted that banks that had never won a CSR award previously seemed to have a better organised structure in respect of their CSR activities on their websites. These findings clearly demonstrate the challenges that sometimes exist in transferring bricks‐and‐mortar organisational capabilities to online environments.Originality/valueStudies focussing on online CSR communications in emerging market contexts are almost non‐existent and this study makes an important contribution in not only addressing this imbalance, but more importantly in improving bank marketing practices in Ghana.
Customer switching behaviour in the Chinese retail banking industry
Authors: Clemes Michael D. , Gan Christopher , Zhang Dongmei 
Published: October 2010

PurposeThere is intense competition and increasing globalisation in financial markets. Bank management must develop customer‐oriented strategies in order to compete successfully in the competitive retail banking environment. The longer a bank can retain a customer, the greater revenue and cost savings from that customer. China's accession to the World Trade Organisation (WTO) has resulted in the liberalisation and deregulation of China's financial services market. Chinese customers now have greater choices between domestic and foreign banks. This study aims to identify and analyse the factors that influence bank customers' switching behaviour in the Chinese retail banking industry.Design/methodology/approachThe data for this analysis was obtained using a convenience sample of 421 bank customers in Jiaozuo City, Henan Province, China. The decision to switch banks is hypothesised to be a function of price, reputation, service quality, effective advertising competition, involuntary switching, distance, switching costs, distance, and demographic characteristics. Factor analysis and logistic regression are used to analyse the data and identify and rank the factors that impact on the bank switching behaviour of customers.FindingsThe research findings reveal that price, reputation, service quality, effective advertising, involuntary switching, distance, and switching costs impact on customers' bank switching behaviour. The findings also reveal that the young and high‐income groups are more likely to switch banks.Practical implicationsThe results of this research allow service marketers and practitioners to develop and implement service marketing strategies to decrease customer defection rates, and in turn, increase bank profits. Furthermore, this research provides useful information for future researchers investigating customer switching behaviour in the retail banking industry.Originality/valueThis paper provides an empirical analysis of Chinese bank switching behaviour and provides a framework for future studies on the behaviour of bank customers.
