AbstractIn Angiosperms, the male gametes are delivered to the female gametes through the maternal reproductive tissue by the pollen tube. Upon arrival, the pollen tube releases the two sperm cells, permitting double fertilization to take place. Although the critical role of the female gametophyte in pollen tube reception has been demonstrated, the underlying mechanisms remain poorly understood. Here, we describe lorelei, an Arabidopsis thaliana mutant impaired in sperm cell release, reminiscent of the feronia/sirène mutant. Pollen tubes reaching lorelei embryo sacs frequently do not rupture but continue to grow in the embryo sac. Furthermore, lorelei embryo sacs continue to attract additional pollen tubes after arrival of the initial pollen tube. The LORELEI gene is expressed in the synergid cells prior to fertilization and encodes a small plant-specific putative glucosylphosphatidylinositol-anchored protein (GAP). These results provide support for the concept of signaling mechanisms at the synergid cell membrane by which the female gametophyte recognizes the arrival of a compatible pollen tube and promotes sperm release. Although GAPs have previously been shown to play critical roles in initiation of fertilization in mammals, flowering plants appear to have independently evolved reproductive mechanisms that use the unique features of these proteins within a similar biological context.

AbstractTranscriptional reprogramming is critical for plant disease resistance responses. In potato (Solanum tuberosum), the marker gene PATHOGENESIS-RELATED-10a (PR-10a) is transcriptionally activated by pathogens, wounding, or elicitor treatment. Activation of PR-10a requires the recruitment of the activator Why1 to its promoter. In addition, PR-10a is negatively regulated by the repressor SEBF (for Silencer Element Binding Factor). Here, we show through a yeast two-hybrid screen that SEBF interacts with Pti4, which has been shown to be a transcriptional activator. SEBF recruits Pti4 via its consensus sequence–type RNA binding domain, while Pti4 is recruited to SEBF by means of its ethylene-response factor domain. In vivo plant transcription assays confirmed that SEBF interacts with Pti4 to form a repressosome, showing that Pti4 can also play a role in transcriptional repression. Chromatin immunoprecipitation revealed that both SEBF and Pti4 are recruited to the PR-10a promoter in uninduced conditions only and that the recruitment of Pti4 is dependent on the presence of SEBF, consistent with the fact that there is no Pti4 consensus binding site in PR-10a. Unexpectedly, we also demonstrated that recruitment of SEBF was dependent on the presence of Pti4, thereby explaining why SEBF, itself a repressor, requires Pti4 for its repressing function.
Recording knowledge‐related activities in practice
Authors: Roberts Stephen A. 
Published: November 2008

PurposeThe paper seeks to offer a generalized methodology for knowledge auditing. The context of information and knowledge perspectives is established and knowledge auditing is located in an evolving context of information research and practice.Design/methodology/approachA 15‐element inventory is developed which takes its design from business strategy and process and links it to the generalized cycle of information and communication activity.FindingsThe elements are systematically reviewed in terms of a general aspect, a typical interpretation and a threshold to indicate the type of practical application and data representation associated with each element.Practical implicationsThe model is widely adaptable to different settings as a tool for business enterprises, organizations in different sectors and for use in communities of practice and learning/knowledge settings.Originality/valueThis is an area of application where a more standard framework approach to information and knowledge auditing would be beneficial. The structure provides a working basis for further development.
Seeking serendipity: the paradox of control
Authors: McBirnie Abigail 
Published: November 2008

PurposeThis paper aims to present selected findings of a recent study of serendipity in information seeking, exploring the paradox of control inherent in the concept of “seeking serendipity”.Design/methodology/approachAfter providing an overview of the research study, the paper locates the research findings in the context of the literature. The discussion explores the research findings in relation to both the paradox of control and the related concept of “seeking serendipity”.FindingsThe definition/description of serendipity is examined, the concept of process‐perception duality is introduced, and links with the literature are explored. The discussion reassesses the paradox of control in light of the research findings, raising the possibility that information literacy educators have a role to play in developing the perception aspect of serendipity.Practical implicationsThe paper proposes that, despite the possibly uncomfortable challenges presented by the paradox of control, serendipity deserves more recognition in professional practice. Increased acknowledgement and understanding of serendipity may enable professional practitioners to function more effectively in the unpredictable, dynamic environment that informs the reality of information seeking.Originality/valueThe paper adds to the limited existing empirical research investigating serendipity, increasing both academic and practical understanding of the phenomenon. In particular, the introduction of the concept of process‐perception duality provides a useful grounding for future research.
The convergence of information systems and information management
Authors: Laurie Bruce A.E. , Roberts Stephen A. 
Published: November 2008

PurposeThis paper aims to provide a reflection on the issue of convergence of information systems and information management using a historical perspective and the experiences of two practitioners from different disciplines working together to deliver first degree and Master's teaching in this area.Design/methodology/approachThe paper situates the teaching of business strategy and information strategy in a historical context and combines this with a reflection on teaching the subject in practice.FindingsThe paper finds that there is a need for exchange of perspectives and skills between information science and information management students which can be mutually beneficial and add value to their skill set.Practical implicationsIn terms of curriculum design for information professional education, information systems students need a strong background in the business and user environment to leverage the technologies for business value.Originality/valueThe paper presents a case study of practice with a commentary on the dynamics of teaching the theme.
Developing small and medium enterprises using knowledge management frameworks
Authors: Radzevičienė Daiva 
Published: November 2008

PurposeThe purpose of this paper is to analyse the role of knowledge management (KM) in small and medium‐sized enterprises (SMEs) in Lithuania by looking at information and knowledge resources, the development of information technology (IT) which supports the business process and the main processes of KM inside companies.Design/methodology/approachQuestionnaires and some interviews within Lithuanian SMEs helped reveal what the present situation is in terms of KM processes and the use of IT.FindingsThere appears to be a strong awareness of KM already. However, the development of adequate methods to make information management (IM) and KM fully effective appears to be lacking or only partially realized. There is some evidence to suggest that Lithuanian SME managers are becoming more psychologically prepared to work within KM but there is much less evidence to show that this is leading to effective innovation in practice at present.Originality/valueThere is great interest in the smaller emergent European economies in particular, and in SMEs in general. Lithuania inherited a stronger asset base than some ex‐Soviet republics and is positioning itself amongst the Baltic economies. With few natural resources, “knowledge” is a key area for growth, but SMEs and other sectors still need to engage strongly in development. SMEs have yet to drive the economy forward.
The small enterprise as the authentic learning environment opportunity (SEALEO)
Authors: Munro Janette , Cook Roger 
Published: November 2008

PurposeThe aim of this study is to address the question of how to provide the appropriate learning environment and experience to foster an entrepreneurial attitude and capture the enthusiasm to shape the future change‐makers in enterprise, entrepreneurship and small business within the cost, resource and timing constraints of higher education in a changing, global and ethnically diverse world.Design/methodology/approachThe methodology for this research on the learning environment is longitudinal action research over more that ten years in the form of a case study. Sources used include student feedback over a number of years at various stages of the learning cycle as well as curriculum and module developments, first destination information with external examiner's and tutor's reports.FindingsOne of the key criticisms of the Honey and Mumford approach is that thinking is treated as concluding not starting. In this model, which revises the Kolb and Honey and Mumford Models, it is suggested that the environment of the learner is integral to the development of the learner. This has formed the basis for a model, which outlines the three dimensions of enterprise in the forms of envisioning, energising, and expediting.Research limitations/implicationsThere is further scope for research by widening the parameters of the research. This could be implemented at other institutions of higher education and gives a solution to one of the cost and resource problems currently besetting higher education globally.Practical implicationsThe key elements of students initially working in teams widens the immediate networks on which they can draw and with the mix in the team they can gain a synergy of vision, energy and expediting. This revision of Kolb's learning cycle is challenging and engaging and makes the participants more fitted for the small and general business environment on graduation.Originality/valueReporting a longitudinal case study with a substantial reflective element, it provides a basis for sharing experience and practice.
Voluntary sector responses to increased resourcing challenges
Authors: Parry Emma , Kelliher Clare 
Published: November 2008

PurposeDrug treatment services in the UK have recently undergone significant expansion, alongside the introduction of a set of quality standards, which included the management of people. Consequently, voluntary organisations in this sector have been faced with the dual challenges of meeting these standards and simultaneously attracting and retaining additional staff in an already tight labour market. This paper aims to examine the response of voluntary sector organisations to these pressures within the wider context of the so‐called “contract culture”, whereby, in order to remain competitive, organisations have experienced continuous pressure on labour costs.Design/methodology/approachThis paper reports findings from a large‐scale nation‐wide survey and interviews with HR Managers.FindingsThe results showed that these organisations had a range of “good practice” HR policies in place and had made some progress in achieving the quality standards, although many struggled to recruit and retain suitable staff. The consequences of these findings are discussed in relation to the literature on both recruitment and retention and HRM in the voluntary sector.Practical implicationsThe paper has practical implications for resourcing practice within the wider voluntary sector.Originality/valueThe authors have provided a contribution to an under researched field through the examination of the challenges facing voluntary sector drug treatment providers in recent years.
Ideals and practices in CSR identity making: the case of equal opportunities
Authors: Lauring Jakob , Thomsen Christa 
Published: November 2008

PurposeThe purpose of the paper is to report on a qualitative research illustrating how equal opportunity ideals as part of a corporate CSR identity project are practiced on the local level.Design/methodology/approachInvestigating the practice of CSR identity making, an ethnographic fieldwork methodology relying on longitudinal participant observations and semi‐structured interviews has been applied.FindingsThe authors argue that the practice of equal opportunities should be understood as a process of local interpretation of generally formulated ideals. By viewing the content of CSR identity as a socially negotiated process, it is suggested that a dynamic approach to the concept is required. The practice of equal opportunity is a continuously negotiated process of identity making and of locally relating ideals to practice in the negotiation between different stakeholders.Research limitations/implicationsThe article is based on a single case study with a limited number of informants.Practical implicationsThis paper has implications for managers who work with CSR initiatives and corporate identity. The authors suggest that policies should be developed in close interaction with the different organizational members. This is necessary in order to manage the mutual expectations. To reach the best results in terms of managing corporate identity, it is necessary to consider CSR as a participative process.Originality/valueEarlier studies on CSR have described corporate identity in static terms, independent of the local practices and interpretations. By applying a process‐oriented theoretical perspective combined with an iterative data collection, new insights into the actual practice of CSR initiatives are provided.
A test of hypotheses derived from self‐determination theory among public sector employees
Authors: Kuvaas Bård 
Published: November 2008

PurposeThe purpose of this study was to test the relationship between intrinsic motivation and work performance among individuals from a broad cross‐section of job types among public employees with the objectives of contributing to self‐determination theory and assisting public management practice and research.Design/methodology/approachRespondents were drawn from three municipalities located in Norway. A questionnaire was distributed to 2,015 employees through a web‐based tool (Questback), which resulted in complete data from 779 workers, representing a response rate of approximately 39 per cent.FindingsThe findings suggest that the relationships between job autonomy and work performance and task interdependence and work performance are partly mediated by intrinsic motivation, while the relationship between supervisor support for autonomy, competence, and development and work performance is fully mediated by intrinsic motivation.Research limitations/implicationsThe two most important limitations, which are discussed in more detail at the end of the paper, are the cross‐sectional nature of the study and the reliance on self‐reported questionnaire data.Practical implicationsThe results support self‐determination theory and suggest that public and private sector managers should pay more attention to autonomy‐supportive work environments.Originality/valueFirst, a recent review of self‐determination theory casts doubt on the performance implications of intrinsic motivation for less complex or interesting tasks. Thus, in order to increase our knowledge of the quality of self‐determination theory as a work motivation theory, empirical research that spans a broad cross‐section of jobs and functions in organisations is needed. Second, and despite the importance of motivation among public employees in an era of transformation to a more business‐oriented approach, there is little empirical research on public sector employee motivation.
Attitudes, attributes and institutions
Authors: Lange Thomas 
Published: November 2008

PurposeThis paper aims to contribute to the growing body of empirical evaluations of workers' subjective well being by assessing the impact of values, beliefs, important job attributes and autonomous institution building on employees' job satisfaction across ten countries in Central and Eastern Europe.Design/methodology/approachData derived from the European Values Study 1999/2000 is being utilised, which provides detailed information not only on job satisfaction and socio‐demographic characteristics, but also on individuals' subjective views, beliefs and important job attributes. Following a descriptive narrative on the transformation in emerging market economies, ordered probit regressions are performed to determine the significance of these characteristics, values and beliefs on workers' job satisfaction.FindingsThe empirical findings suggest that reported attitudes, values and beliefs and their impact on job satisfaction evince traits of a legacy of communist industrial relations as well as subsequent experiences with economic and social transition. What is more, the study also uncovers the positive influence of trust and confidence in autonomous institution building on workers' job satisfaction, specifically in the context of reformed trade unions, education and social security.Originality/valueIn previous studies, job satisfaction has been examined primarily in Western Europe and the USA. In contrast, empirical examinations to identify the determinants of job satisfaction for employees in Central and Eastern Europe have not figured prominently in this literature. This paper adds value by providing robust empirical results for this region.
A metadata manager's role in collaborative projects
Authors: Sun Li 
Published: November 2008

PurposeThis paper seeks to discuss the roles and responsibilities of a metadata manager in collaborative digital projects.Design/methodology/approachThe paper describes the general requirements for metadata management, and introduces some scenarios in the practices of digital projects by the Rutgers University Libraries to support the generalized definition. A workflow of metadata management is illustrated.Practical implicationsWith an explicit definition of the roles and responsibilities of the metadata manager, many other digital libraries that need to develop a new or optimize the existing workflow may find the Rutgers experience useful as a reference.Originality/valueVery few papers have explored this topic, although the functions of metadata in the development of digital projects have been talked about extensively.
Twenty‐three steps to learning Web 2.0 technologies in an academic library
Authors: Gross Julia , Leslie Lyn 
Published: November 2008

PurposeThis paper aims to report on the adoption and evaluation of a Learning 2.0 program in a pilot program at the Edith Cowan University Library during 2007.Design/methodology/approachThe paper examines the suitability of Learning 2.0 for training eight “early adopters” among library staff in the new and emerging Web 2.0 technologies. The program was set up and deployed via a blog, which recorded staff progress through the nine‐week implementation phase of the program. At the conclusion, a focus group was held and the pilot group members responded to questions about the relevance of the program, and the effectiveness of their learning.FindingsIt was found that library staff responded positively to this program, not least because it adhered to adult learning principles. For the authors' purpose, Learning 2.0 was an eminently suitable training package.Originality/valueThe paper is unique in that Edith Cowan University Library was the first Australian university library to adopt Learning 2.0.
Collaborative design: a learner‐centered library planning approach
Authors: Somerville Mary M. , Collins Lydia 
Published: November 2008

PurposeInformation commons were introduced into libraries in the early 1990s. Now universities are building library learning commons and campus learning spaces. This paper sets out to present a participatory library (re)design approach for collaborative planning “for and with” faculty teachers, student learners, and campus stakeholders.Design/methodology/approachCollaborative design (co‐design) employs user‐centric investigations to produce products, applications, and environments aimed at advancing learning, sustaining communication, and building relationships. Examples from California Polytechnic State University and San José State University in California, USA, suggest the efficacy of this inclusive, learner‐centered (re)design approach for library facilities, services, and systems.FindingsInviting and enabling user input from the start offers a fruitful planning approach in which campus librarians, stakeholders, and beneficiaries “learn their way” to appropriate library (re)design decisions. Also, user involvement in information gathering and interpretation activities initiates the interactive relationships necessary for continuous improvement.Practical implicationsCollaborative design (co‐design) yields sustained interaction with user beneficiaries and campus stakeholders. It changes how library staff members think and what they think about, concurrent with enhancing libraries' appeal and value.Originality/valueIn development since 2002, the highly participatory design approach reflects theoretical and applied insights from researchers in Europe, Australia, and North America who have worked with US library practitioners to develop user‐centric processes for advancing organizational learning and enhancing user efficacy. Its practical application to planning for library learning commons and learning spaces contributes to the small but important literature on user‐centered library (re)design.
Digital libraries in the mirror of the literature: issues and considerations
Authors: Isfandyari‐Moghaddam Alireza , Bayat Behrooz 
Published: November 2008

PurposeThe purpose of this paper is to review the literature of digital libraries (DLs), explore some issues and indicate some considerations. The paper also demonstrates the current situation and orientation of research topics and priorities in DLs.Design/methodology/approachKeywords such as “DL research”, “DL evaluation”, “DL management”, “DLs”, “DL studies” and so on were searched for on the web as well as in some leading databases, including Emerald, Proquest, SagePub, ScienceDirect and Springer. The search focused on three main categories in relation to DL literature: evaluation or performance appraisal, management, and education.FindingsThe review demonstrates that a lot has been learned in a short time via DL studies. However, a number of issues are yet to be resolved. In other words, research in the arena of DLs is still growing and it is predicted that new horizons will emerge, along with a variety of issues.Research limitations/implicationsThe review does not claim to be comprehensive.Practical implicationsIt is hoped that matters such as legal issues, social issues, standards, metadata, management of intellectual and digital rights and interoperability, not included here, will be discussed in future works.Originality/valueThe paper can serve as a road‐map of digital library research for researchers, designers and users.
