Abstract
Flavonoids are secondary metabolites known to modulate plant growth and development. A primary function of flavonols, a subgroup of flavonoids, is thought to be the modification of auxin fluxes in the plant. Flavonols in the cell are glycosylated, and the repressor of lrx1 (rol1) mutants of Arabidopsis thaliana, affected in rhamnose biosynthesis, have a modified flavonol glycosylation profile. A detailed analysis of the rol1-2 allele revealed hyponastic growth, aberrant pavement cell and stomatal morphology in cotyledons, and defective trichome formation. Blocking flavonoid biosynthesis suppresses the rol1-2 shoot phenotype, suggesting that it is induced by the modified flavonol profile. The hyponastic cotyledons of rol1-2 are likely to be the result of a flavonol-induced increase in auxin concentration. By contrast, the pavement cell, stomata, and trichome formation phenotypes appear not to be induced by the modified auxin distribution. Together, these results suggest that changes in the composition of flavonols can have a tremendous impact on plant development through both auxin-induced and auxin-independent processes.

AbstractGlycosyltransferases are involved in the biosynthesis of lipid-linked N-glycans. Here, we identify and characterize a mannosyltransferase gene from Arabidopsis thaliana, which is the functional homolog of the ALG3 (Dol-P-Man:Man5GlcNAc2-PP-Dol α1,3-mannosyl transferase) gene in yeast. The At ALG3 protein can complement a Δalg3 yeast mutant and is localized to the endoplasmic reticulum in yeast and in plants. A homozygous T-DNA insertion mutant, alg3-2, was identified in Arabidopsis with residual levels of wild-type ALG3, derived from incidental splicing of the 11th intron carrying the T-DNAs. N-glycan analysis of alg3-2 and alg3-2 in the complex-glycan-less mutant background, which lacks N-acetylglucosaminyl-transferase I activity, reveals that when ALG3 activity is strongly reduced, almost all N-glycans transferred to proteins are aberrant, indicating that the Arabidopsis oligosaccharide transferase complex is remarkably substrate tolerant. In alg3-2 plants, the aberrant glycans on glycoproteins are recognized by endogenous mannosidase I and N-acetylglucosaminyltransferase I and efficiently processed into complex-type glycans. Although no high-mannose-type glycoproteins are detected in alg3-2 plants, these plants do not show a growth phenotype under normal growth conditions. However, the glycosylation abnormalities result in activation of marker genes diagnostic of the unfolded protein response.
Narrative disclosure of intellectual capital
Authors: Dumay John C. 
Published: June 2008

PurposeThe purpose of this paper is to investigate the manner and impact of intellectual capital (IC) disclosure. To frame the discussion, elements of Giddens' “structuration” theory and narrative theory are used to analyse change from within an organisation.Design/methodology/approachUsing a case study approach, this paper explores the impact of the narrative disclosure of IC by an Australian public sector organisation, the New South Wales (NSW) Department of Lands (Lands), which is the first Australian government organisation to externally disclose IC.FindingsBy taking a structuralist approach to analysing the narrative disclosure of IC this paper moved beyond attempting to quantify or identify the wealth created by IC, and thus account for IC. By investigating the narrative disclosure of IC, initially in the form of the IC statement as a supplement to the annual report, it was shown how at Lands the use of narrative became routinized in the activities of management. Thus narrative was no longer used to only provide understanding of the IC measures and the reasoning behind the use of IC, but to provide a mechanism that engendered further management action and subsequent organisational change.Research limitations/implicationsThe limitation of this paper is that it provides a lone example of a particular organisation from which generalisations are not possible. But it is possible to extend this research, using the structuration framework, to other organisations that have engendered the use of narrative to disclose IC to both internal and external stakeholders. Doing so will further question the domination of “accounting” within the IC paradigm and provide additional insights that allows practitioners and academics to develop additional tools for understanding and utilising IC.Originality/valueThis paper investigates the manner and impact of IC disclosure from within an organisation by use of “structuration” and narrative theory to analyse change as a result of the implementation of IC practices.
Investigating project managers' work values by repertory grids interviews
Authors: Song Shi‐Rui , Gale Andrew 
Published: June 2008

PurposeThe purpose of the research is to investigate project managers' work values and their relationship with project managers' competence.Design/methodology/approachIn this research, the authors conducted semi‐structured interviews using repertory grid techniques on 18 Chinese project managers. Three different approaches are utilised to analyse data obtained from the interviews.FindingsThe authors categorised work values with different perspectives. Project managers' core work values are identified.Research limitations/implicationsThe authors recommend that work values are an important dimension in relation to project manager's competence. The understanding of a project manager's work values has a potential application in human resources development and competence‐based management development.Originality/valueThis paper presents an innovative approach to the investigation of a project manager's competence.
Development and evaluation of SPAT: a web page assessment tool
Authors: LaRue Elizabeth M. 
Published: June 2008

PurposeThe purpose of this research is to measure the validity and the adoption of a new web page assessment tool called SPAT (Site, Publisher, Audience, Timeliness).Design/methodology/approachA convenience sample of 37 Certified Diabetes Educators (CDEs) participated in an evaluation of the web page assessment tool SPAT. Four web pages with diabetes content were selected for a pre‐ and post‐test evaluation. A follow‐up questionnaire measured adoption of the SPAT tool.FindingsThere was a significant difference when using the mnemonic SPAT to evaluate the site, publisher and timeliness of a web page. Using SPAT to evaluate the audience of a web page also showed an improvement. While there was an increase in reviewing the text of a web page for biases after the SPAT intervention, it was not significant. The CDEs easily utilized SPAT with the diabetes content web pages and their successful manipulation of the SPAT tool demonstrated face validity. After learning of SPAT, responses to the follow‐up questionnaire revealed adoption of the tool by CDEs.Practical implicationsUse of SPAT may enable health care providers to systematically evaluate health‐related web page content.Originality/valueSPAT is a novel tool that reinforces a user to practice basic literacy concepts. The value of SPAT is that it is a people centered tool that may easily be used by anyone to evaluate web pages.
Copyright in the networked world: gray copyright
Authors: Seadle Michael 
Published: June 2008

PurposeThis paper uses an inductive approach to define “gray copyright.” It is needed to describe those situations in which the practical degree of copyright protection can best be measured in shades of risk rather than in simple terms of black and white.Design/methodology/approachTwo methods are used. One is an inductive definition builds up the term's meaning example by example and layer by layer. The second is a behavioral experiment in the spirit of the prisoner's dilemma game.FindingsIn the examples of gray copyrights the deciding factor in the grayness is not its legal status, but the economic value of enforcing the usage rights. In the experiment the students have an opportunity to acquire a personal sense of the risks and choices involved in copyright infringements.Originality/valueThis analysis shifts the emphasis from the question of legal right and wrong to the economic issue of what risks are potential infringers and rights holders prepared to take.
Interpretive structural modeling (ISM) of IT‐enablers for Indian manufacturing SMEs
Authors: Thakkar Jitesh , Kanda Arun , Deshmukh S.G. 
Published: June 2008

PurposeThis paper aims to investigate the issue of information technology (IT) adoption and implementation in Indian manufacturing small‐ and medium‐scale enterprise (SMEs) towards enhancing the capabilities of their supply chain.Design/methodology/approachExtracts of recently completed case‐based research for ten SME units are utilized for the identification of IT‐enablers. To support the logical deduction of the factors, diagnostic techniques like force‐field analysis, situation‐actor‐process and learning‐action‐performance are used. Further, key managerial insights were obtained by developing an interpretive structural modeling (ISM) model for the set of factors, specific to Indian context.FindingsISM delivers interrelationships among the factors which were utilized for deriving managerial insights. Further, these factors are classified into four categories, namely, autonomous, driver, dependent, and linkage to understand their relative impact on the implementation of IT in Indian SMEs.Practical implicationsThe advancement in IT presents opportunities for SMEs to harness the benefits of information and communication technologies in an affordable, simple way and to reach new customers and suppliers in global competition and at large to improve their supply chain competencies without a need for any major changes in business practices, manufacturing operations or production facilities. The findings of the present research will help Indian SME managers to enable IT implementation with a strategic orientation.Originality/valueKey issues related to IT implementation in SMEs are discussed and interconnectedness of critical factors for the case of Indian SMEs is understood.
Remaining consistent with method? An analysis of grounded theory research in accounting
Authors: Gurd Bruce 
Published: June 2008

PurposeThe paper revisits the intellectual roots of grounded theory and aims to analyze the consistency of the method used in grounded theory research in accounting. About 23 papers are identified and analysed.Design/methodology/approachThe paper is an analytical review of the research literature. It uses four fundamental canons of grounded theory to analyze accounting research.FindingsSome accounting researchers who have used the label “grounded theory” for their research have misunderstood or not applied the core canons of grounded theory established by Glaser and Strauss and developed with diversity in other disciplines. Most claim to follow the specific approach of Strauss and Corbin, but the published research shows limited explication of method.Originality/valueSince Parker and Roffey in 1997, there has been no analysis and re‐evaluation of the burgeoning academic accounting literature using grounded theory. While celebrating the growth of this research, the paper does raise concerns about the lack of consistency of grounded theory research in accounting with the central canons of grounded theory, and it provides some directions for future grounded theory research by encouraging accounting researchers who wish to use grounded theory to engage more strongly in understanding the method and providing transparent explanations of their data collection and analysis methods.
Leadership team performance management: the case of BELRON
Authors: Houldsworth Elizabeth , Machin Simon 
Published: June 2008

PurposeThe purpose of this paper is to present a case study around an approach to team performance management being deployed within the BELRON group of companies. The device being deployed is the climate measure (OCSII), which is being used within the organisation as an indicator of leadership capability. Although the results of climate surveys may be reported at both team and individual levels, this paper seeks to focus on team climate and how this may be linked to changes in business performance.Design/methodology/approachThe performance management approach has been aligned to a strategic intent, as championed by the CEO, to focus on leadership development as a key enabler of BELRON's future success. The paper considers the deployment of the climate tool within the Top Teams of three different business units and this is linked to available information relating to performance.FindingsThe paper finds that, within BELRON, there is a belief that the emphasis on climate has been a major contributor to its enhanced business performance over recent years. The paper presents information from three BELRON contexts where changes in climate would appear to precede improvements in business performance. However, despite these examples, i.e. where “high performing climates” appear to be linked with profitability, or other measures of business performance, this is not seen to be universal within the company.Research limitations/implicationsThe work reported has limitations in that it focuses on only three positive examples of a possible climate/performance link at BELRON.Practical implicationsThe paper makes a key contribution for practitioners, particularly HR, OD professionals and consultants as well as any senior manager concerned with managing performance. The climate survey being deployed in this context (the OCSII) is a tool which has been in use since the 1960s, with many claims made about its links to performance. However, the vast majority of the work has been conducted in a consultancy setting without much coverage in academic literatures.Originality/valueThe paper describes for the reader how the OSCII tool may be deployed to support team performance management. It then describes how the instrument has been deployed within the Top Teams of three business units within BELRON.
Enhancing organisational learning in teams: has the middle manager got a role?
Authors: Costanzo Laura A. , Tzoumpa Vicky 
Published: June 2008

PurposeThe purpose of this paper is to provide a deeper understanding of the managerial processes that middle managers can employ to facilitate knowledge integration and transfer within project teams and across organizational boundaries.Design/methodology/approachThe paper has a conceptual framework, which draws on the theory of organizational learning and knowledge management. A resource‐based view of the firm and middle management is developed around the theme of enhancing organizational learning within teams.FindingsThe paper finds that there is a gap in the research as to how knowledge integration and transfer occur within teams. The paper also provides a re‐valuation of middle managers, whose role has been undermined in the wake of organizational downsizing. Furthermore, the paper provides an understanding of how Janczak's three specific managerial processes are relevant in that middle managers can employ them to facilitate knowledge integration and transfer.Practical implicationsThe paper is relevant to practitioners with regard to the practices and processes that middle managers can adopt to facilitate knowledge transfer. It is relevant in that it helps to identify mechanisms to reuse knowledge from project to project.Originality/valueThe paper fills a gap in the theory with regard to the managerial practices and processes that are available to middle management in order to enhance organizational learning within the team and from the team to the rest of the organization.
Seasonality in rural tourism – the case of North Portugal
Authors: Kastenholz Elisabeth , Lopes de Almeida António 
Published: June 2008

PurposeIn this paper, the aim is to discuss and analyze seasonality of demand within the rural tourist market of North Portugal and corresponding destination marketing implications.Design/methodology/approachThe data (n=2280) were collected through a large‐scale survey in the context of a study of the rural tourist market in North Portugal, from 1998 to 1999.FindingsResults reveal statistically significant differences between those coming in the high versus low season, concerning tourist profile, travel behavior, motivations and perceptions of the destination.Research limitations/ implicationsThe study results may only be valid for the specific rural region studied, which would make replication studies in other rural destinations desirable to take more generalizable conclusions.Practical implicationsUnderstanding seasonal market differences and confronting them with the destination's resources may contribute to the development of more attractive products and correspondingly to the destination's ability to attract and satisfy different types of tourists in different seasons of the year. The capacity to thereby improve the destination experience in the eyes of its tourists and to also manage demand, avoiding excessive crowding in the high season and eventually sub‐optimal use of resources in the low, may be an important step for maintaining a sustainable tourism business in rural areas.Originality/valueThe paper aims at contributing to the discussion of how to cope with seasonality of tourist demand, considering particularly the specificity of rural destinations and the global aim of sustainable destination development.
Destination networks and induced tourism image
Authors: Camprubí Raquel , Guia Jaume , Comas Jordi 
Published: June 2008

PurposeThe aim of the paper is to develop a conceptual model of the process by means of which the induced tourism image of a destination is created. The model focuses on the role tourism agents' relational networks play in this process and particularly on the effects of the links with external actors – i.e. tour‐operators – on the destination's induced image.Design/methodology/approachBased on Gartner's definition of image formation agents, it is assumed that there are tourism agents that use the tourism image as a pull factor to influence the buying behaviour of potential visitors. Basically, these agents are: internal actors, located within a particular tourism destination, and external agents – i.e. tour‐operators – which are not normally associated with any particular destination, but have stakes in the travel decision process of potential visitors. In parallel, it is assumed that the tourism destination is a web of relational networks where the agents are connected by means of collaborative links that facilitate the supply of a tourist product or experience to the visitors.FindingsIn this paper two potential gaps in the induced tourism destination image formation process are found, and that the position of relevant actors in the network and the structure of the network are two determinant factors of the emergence – or inhibition – of these gaps. It is also suggested that these gaps and the lack of collaborative links among internal and external actors would affect the coherence of the supplied tourist products and the satisfaction with the tourist experience.Originality/valueThe relevance of the paper lies in a new approach to the induced tourism image formation process focusing on the destination's relational network and, in particular, the network of relations with external agents (i.e. tour‐operators).
Young compulsive buyers and the emotional roller‐coaster in shopping
Authors: Saraneva Anna , Sääksjärvi Maria 
Published: June 2008

PurposeThe purpose of this paper is to examine the emotions young compulsive buyers experience while shopping.Design/methodology/approachThe authors conducted a digital ethnography study by communicating with 22 young compulsive buyers for two weeks using their cell phones while they were engaged in the shopping activity.FindingsThe results show that the emotions experienced by compulsive buyers are much more complex than previously thought. The emotions young consumers go through during the shopping process are not predominantly negative or positive. Instead, young consumers move up and down on an emotional continuum during shopping. The trigger involved with the emotions is linked to finding a bargain. A bargain is defined as a good deal, or a situation in which the consumers perceive they get mental satisfaction from their purchase. If young compulsive shoppers find a bargain, they feel pride, happiness, and goal achievement. However, if they do not manage to find a bargain, they feel disappointed, sad, and unsuccessful.Research limitations/implicationsThis study was focused on adolescent consumers. Although this age group is considered suitable for conducting a study of compulsive buying, the results cannot be generalized to other age groups.Originality/valueCompared to previous studies, the paper uncovers emotions and emotional shifts in much greater detail, providing new insights to the phenomenon of compulsive buying, considering the range of emotions that consumers experience, and the triggers involved with their emotional shifts.
Teenagers, blogs and socialization: a case study of young French bloggers
Authors: Muratore Isabelle 
Published: June 2008

PurposeThe aim of this paper is to better understand the world of blogs and youngsters by describing and trying to understand the young blogger. It is a first step towards questioning not only the importance of blogs for youngsters, but also the fact that blogs might constitute a virtual form of peer socialization.Design/methodology/approachThe first part of the paper deals with an account of blogs, and with peer socialization. The second part shows the results of a case study (Miss34) and of a qualitative study that allows us to better understand teenagers, blogs and socialization. Based on these pieces of information, the third part presents a discussion of the results as well as their managerial implications.FindingsThe blog is a very different mode of expression compared with others that teenagers may have access to. Blogs are not all different but, have similarities. Finally, with regard to socialization, the blog is not a substitute for the forum. Strictly speaking, teenagers essentially do not use blogs to give their opinion on products or services, but sometimes speak about products and services they buy. On the other hand, a more “passive” kind of socialization is going on through blogs.Research limitations/implicationsThis paper is exploratory. The aim is not to generalize from these results. A suggestion for a future research will be to use a quantitative approach in order to be able to measure this phenomenon.Practical implicationsFrom a managerial point‐of‐view, the aim is to target the youngsters better through a better understanding of their world.Originality/valueThis paper is the first work on virtual socialization by peers.
