Abstract
Nonfluorescent chlorophyll catabolites (NCCs) were described as products of chlorophyll breakdown in Arabidopsis thaliana. NCCs are formyloxobilin-type catabolites derived from chlorophyll by oxygenolytic opening of the chlorin macrocycle. These linear tetrapyrroles are generated from their fluorescent chlorophyll catabolite (FCC) precursors by a nonenzymatic isomerization inside the vacuole of senescing cells. Here, we identified a group of distinct dioxobilin-type chlorophyll catabolites (DCCs) as the major breakdown products in wild-type Arabidopsis, representing more than 90% of the chlorophyll of green leaves. The molecular constitution of the most abundant nonfluorescent DCC (NDCC), At-NDCC-1, was determined. We further identified cytochrome P450 monooxygenase CYP89A9 as being responsible for NDCC accumulation in wild-type Arabidopsis; cyp89a9 mutants that are deficient in CYP89A9 function were devoid of NDCCs but accumulated proportionally higher amounts of NCCs. CYP89A9 localized outside the chloroplasts, implying that FCCs occurring in the cytosol might be its natural substrate. Using recombinant CYP89A9, we confirm FCC specificity and show that fluorescent DCCs are the products of the CYP89A9 reaction. Fluorescent DCCs, formed by this enzyme, isomerize to the respective NDCCs in weakly acidic medium, as found in vacuoles. We conclude that CYP89A9 is involved in the formation of dioxobilin-type catabolites of chlorophyll in Arabidopsis.
The CARM2 print repository: from planning to operations
Authors: Jilovsky Cathie 
Published: May 2013

PurposeThe purpose of this paper is to present a case study of the planning and construction of a print repository for CAVAL, an Australian consortium of academic libraries. A key service is the management of the CARM (CAVAL Archival and Research Materials Centre), a purpose‐built, high‐density, environmentally controlled storage facility designed for the long‐term storage and preservation of print materials. The initial module, CARM1, began operations in 1996 and filled to capacity over a ten year period. To meet predicted demand for ongoing storage of low‐use paper‐based research materials, CAVAL has now built a second storage facility, CARM2.Design/methodology/approachThe planning for CARM2 commenced with a review that assessed options available to CAVAL member universities for the long term storage of low‐use print material. This review analysed alternative storage solutions from the perspective of university users to assess the financial and non‐financial impacts associated with each option. The results provided an indicative evaluation of the comparison of alternative storage options taking into consideration the quantitative, qualitative and risk implications of each from the perspective of a potential user. Nine options are described and analysed, and the reasons for the selection of the CARM2 option as the preferred model.FindingsThe development and implementation of the business model, the impact on the design and funding model, the lessons learned from the management of the original CARM facility and the construction and commissioning of CARM2 are described. This is followed by a discussion of ongoing issues associated with the ownership and governance of the shared facility and the trends away from the shared collection model.Originality/valueThis paper will be of interest and value to other organisations or consortia with an interest in the feasibility, possible business models, development and construction, and/or operations of a print repository.
Customer service experiences
Authors: Jüttner Uta , Schaffner Dorothea , Windler Katharina , Maklan Stan 
Published: May 2013

PurposeThe purpose of this paper is to develop and apply the sequential incident laddering technique as a novel approach for measuring customer service experiences. The proposed approach aims to correspond with the concept's theoretical foundation in the extant literature.Design/methodology/approachThe paper applies the sequential incident laddering technique to measure customer service experiences. The technique integrates two well‐established methods in service marketing: sequential incident and laddering techniques. The data collected from 41 customers in a hotel and restaurant experience context illustrate that the method corresponds with the key themes of the proposed experience concept and experience formation process.FindingsApplying the proposed technique reveals first, the customer's cognitive and emotional responses to company stimuli. Second, the salient customer cognitions and emotions across several episodes of the service interaction process are identified. Third, the personal values which drive the customer's service experience are disclosed.Research limitations/implicationsThe empirical study is a first illustration of the proposed measurement approach in only one company based on a limited sample size. The methodological contributions and development opportunities for further applications are set out for different contexts and in combination with other methods.Practical implicationsThe proposed method integrates customer and company‐related constructs. Therefore, the data collected can provide managers with guidelines for customer service experience design based on detailed customer feedback.Originality/valueThe paper proposes an innovative measurement approach to customer service experiences which can support knowledge development in an important marketing area.
The effect of teams on customer knowledge processing, esprit de corps and account performance in international key account management
Authors: Salojärvi Hanna , Saarenketo Sami 
Published: May 2013

PurposeThis study aims to examine what the role of key account teams is in the management of international key account customers in terms of customer knowledge processing behaviours of the supplier, esprit de corps of employees and supplier's key account performance.Design/methodology/approachSurvey data from large industrial firms in Finland are used to compare the differences between supplier firms having a team and those not having a team for managing the key account customer.FindingsThe results reveal a higher perceived level of customer‐knowledge acquisition, dissemination and utilisation, and of suppliers' key account performance, in the group representing team‐based key account management compared with the non‐team group.Originality/valueThe article is one of the first studies in which the role of teams in the management of international key account customers is examined based on empirical, quantitative data.
Quality‐based excellence and product‐country image: case studies on Italy and China in the beverage sector
Authors: Rubini Lauretta , Motta Luca , Di Tommaso Marco R. 
Published: May 2013

PurposeThe aim of this paper is to emphasize the role of the place of origin in overcoming the information asymmetries that characterize in particular “experience” and “credence” goods.Design/methodology/approachAfter having summarized the role of the country‐of‐origin (COO) in facilitating producers to effectively communicate to consumers the quality of their products, the article presents two case studies: the Chianti Classico wine from Tuscany (Italy) and the tea industry in Guangdong (China).FindingsBoth wine and tea have strong links with their place of origin. The two case studies show that business excellence depends not only on firms' strategy, but also on the territory where firms are located. In the case of Chianti Classico, the territorial brand plays a strategy role for product promotion, while Guangdong seems to be less effective in allowing consumers to perceive, and therefore to appreciate, the tea quality at the international level. This makes it possible to draw from the Italian case some indications that could be applied to the Chinese case but also to other productions in the world where the link with the territory is not sufficiently valorized.Research limitations/implicationsDespite the impossibility of drawing general conclusions from case studies, the two selected ones can be considered as emblematic of two different territorial strategies that over time led to two different results. This could be the starting point for policy makers aimed at valorizing the importance of territory for increasing business excellence.Practical implicationsThe analysis suggests that connecting the products to their territory of origin can help firms communicate to consumers the quality of their items. The country of origin can be a powerful tool to reinforce a corporate brand, but of course it means admitting that the competitive advantage of a firm is also the result of collective public or private actions devoted to create and communicate a positive image of a specific locality. This implies a joint effort of firms and policy makers.Originality/valueThe paper underlines the similarities between two apparently very distant products, wine and tea. To appreciate such a similarity makes it possible to identify success factors of one sector that can be used to overcome the weaknesses of the other. The indications that arise from the analysis can also be the basis to re‐define the strategy of several other “credence” goods that require the provision to consumers of tools facilitating their process of quality appreciation of products.
Gender stereotyping effects on entrepreneurial self‐efficacy and high‐growth entrepreneurial intention
Authors: Sweida Gloria L. , Reichard Rebecca J. 
Published: May 2013

PurposeThe number of women choosing entrepreneurship as an occupation continues to grow. However, there are very few start‐up high‐growth ventures in traditionally non‐feminine industries, such as manufacturing or technology. The purpose of this paper is to draw attention to the potential impact of implicit and explicit gender stereotypes on women's high‐growth entrepreneurial intention, and to examine the role of entrepreneurial self‐efficacy in this process. The authors aim to argue that there is a dual stereotype associated with high‐growth entrepreneurship (HGE), which negatively impacts on women's intention and self‐efficacy, thereby limiting their behavior in this arena.Design/methodology/approachThis is a conceptual paper. Through the lens of stereotype activation theory the authors call for researchers to begin examining these phenomena and to utilize more generalizable samples of entrepreneurial students in future research.FindingsThe paper finds that by decreasing the masculine stereotype‐related barriers associated with HGE and increasing women's HGE self‐efficacy it should be possible to increase women's intention to engage in high‐growth venture creation.Research limitations/implicationsThe paper has valuable implications for entrepreneurship educators and trainers.Practical implicationsThe paper offers specific and practical suggestions on how entrepreneurship educators and trainers can build women's entrepreneurial self‐efficacy.Originality/valueIn this paper, the authors bring together prior theory and research on entrepreneurship, gender stereotyping and social cognitive theory to provide a research agenda on the relationship between stereotype threat, entrepreneurial self‐efficacy and high‐growth entrepreneurial intention.
Financial availability and government support for women entrepreneurs in transitional economies
Authors: Iakovleva Tatiana , Solesvik Marina , Trifilova Anna 
Published: May 2013

PurposeThis paper studies female entrepreneurship in two post‐Soviet countries – Russia and Ukraine. Employing institutional theory, the research aims to investigate the entrepreneurial environment, particularly government support programmes and the availability of financial resources, with a focus on women entrepreneurs.Design/methodology/approachThis research is a qualitative investigation that comprises 60 interviews with Russian and Ukrainian entrepreneurs, bank officers and representatives of government organisations supporting the development of entrepreneurship.FindingsThe investigation provides evidence that these countries have overcome the transition from a command to a market economy and local people are gradually adjusting to the new environment. Concentrating on macro/meso and money elements from the 5M model suggested by Brushet al., the authors suggest an additional construct – “motherland” – to embed a context in a new model.Research limitations/implicationsOnly two factors of Brushet al.'s 5M model were considered – i.e. macro/meso environment and money (availability of financial resources). Discussion of management, marketing and motherhood is beyond the scope of the present paper.Practical implicationsThe study reveals a broad range of managerial information and empirical data on the development of female entrepreneurship in contemporary Russia and Ukraine. The findings are helpful for policymakers engaged with these two countries.Originality/valueThe study is an attempt to capture the context dependency of research on female entrepreneurs, and suggests a new dimension for inclusion in Brushet al.’s 5M model – “motherland”.
The socio‐political, economic, and cultural determinants of social entrepreneurship activity
Authors: Griffiths Mark D. , Gundry Lisa K. , Kickul Jill R. 
Published: May 2013

PurposeThe purpose of this paper is to incorporate the demand and supply‐side theories of entrepreneurship development in a series of stage‐based models that analyze how macro‐level and contextual variables influence social entrepreneurship activity. The paper investigates the macro‐level influences, including the socio‐political, cultural and economic factors that can stimulate or impede the emergence of social entrepreneurship. Although little research on these determinants has been conducted, this study seeks to reveal that several variables that are crucial in traditional entrepreneurial studies do not appear to significantly affect social entrepreneurship.Design/methodology/approachTo measure social entrepreneurial activity, the authors used the Global Entrepreneurship Monitor (GEM) findings from the 2009 study. Hierarchical multiple regression was used to test three multi‐level stages of the socio‐political, economic, and cultural determinants of social entrepreneurship activity. The series of three stages for all of the variables were entered in the following order: first, socio‐political variables; second, cultural variables; third, economic variables. This approach allows the authors to explore and thus extend the previous research reviewed here, on how the economic context beyond socio‐political and cultural factors affects social enterprise activity.FindingsA three‐stage analysis revealed that socio‐political variables accounted for 76 percent of the variance in social entrepreneurial activity. It was found that the single greatest determinant of social entrepreneurial activity is the degree of female participation in the labor force. Additional findings and implications for understanding the role of macro‐level factors on social entrepreneurship are discussed.Originality/valueSocial entrepreneurship has the potential to confront and address some of society's most challenging and complex problems arising from market and government inadequacies or failures. Social entrepreneurial firms exist within environments that are often severely resource‐constrained. Therefore, social entrepreneurs may rely on a unique set of strategies to mobilize resources available to them, such as collaboration with others and accessing social capital to generate value solutions for their communities. The growth of women's participation in the labor force is a powerful influence on social entrepreneurship activity, and with the increase in training programs and local networks to support women's business ownership, it is likely that this trend will continue and positively impact communities around the world.
Teaching children with disabilities: ICTs in Bangkok and Addis Ababa
Authors: Schiemer Margarita , Proyer Michelle 
Published: May 2013

PurposeThis paper intends to explore the levels of availability and restrictions in relation to the use of ICTs (information and communication technologies) for educating children with disabilities in Thailand's and Ethiopia's capitals.Design/methodology/approachIn the course of an international research project, parents and teachers of children with different disabilities, the children themselves and further experts were interviewed about barriers and facilitators in the children's educational environment. For this paper only selected interviews focusing on sensory disabilities were analysed regarding the above mentioned areas of using ICTs.FindingsICTs are available in the respective cities. The levels of restrictions related to the socio‐economic situation in the two cities vary accordingly but show the same overall limitations. The intensity and kind of use of ICTs is strongly related to resources, the educational actors' awareness and knowledge.Originality/valueApproaching the topic of ICTs in relation to disability might not be new, neither is the contextualisation with the Majority World. However, the combination of the three aspects against the background of current global developments (e.g. the growing gap between the poor and the rich) reveals the importance of taking a closer look at special needs education and ICTs in the Majority World. This opens the floor for discussion on how inclusion of the most marginalised groups in education affects development in general.
Multiple cultures of doing geography facilitate Global Studies
Authors: Ahamer Gilbert 
Published: May 2013

PurposeThis article aims to explain why geography is a prime discipline for analysing globalisation and a multicultural view of Global Studies. The generic approach of human geography to first select an appropriate methodology is taken as a key approach.Design/methodology/approachConcepts from aggregate disciplines such as history, economics, and geography are scanned through during a short description of the historical genesis of these sciences and the paradigmatic shifts they have encountered.FindingsThere are four main theses: (1) values are created by appreciation; (2) development is growing jointly with responsibility; (3) accumulation of material value is seen as expenditure to achieve non‐material values; and (4) spatial relations are interrelated with social relations.Research limitations/implicationsConceptual considerations have to be further corroborated by quantitative analyses using suitable metrics of “development”.Practical implications“Social and cultural geography” should contribute to any curriculum of “Global Studies”.Social implicationsDialogue and discourse between world views is the essential, ideology‐free approach for understanding globalisation.Originality/valueUnlike other scientific articles focusing on “facts”, this article focuses on perspectives. Thus, it explains “multi‐perspectivity” and a multi‐paradigmatic approach.
Aligning strategies and processes in knowledge management: a framework
Authors: Bosua Rachelle , Venkitachalam Krishna 
Published: May 2013

PurposeKnowledge management (KM) has become a key driver of organisational performance. The existing literature suggests that many organisations fail in their attempts to align their KM strategies with knowledge processes within their organisation. Based on the management literature on alignment, there is a gap in the understanding of how an organisation's KM strategy and KM processes in workgroups can be aligned. The purpose of this paper is to illustrate that alignment in terms of KM is important and underpins the improvement of KM processes in organisations.Design/methodology/approachA qualitative case study research approach was used to examine alignment between strategy and processes of knowledge in organisations. In total, three case organisations representing different industry sectors were chosen to examine how organisations align their KM strategies with workgroup knowledge processes.FindingsThis study proposes a Strategic‐Workgroup Alignment Framework that explains the key alignment enablers and different alignment approaches required to align KM strategy with workgroup KM processes in organisations.Research limitations/implicationsThe authors acknowledge the limitations of this paper. Although the proposed framework provides valuable insights with respect to different alignment approaches, it does not specify how each alignment approach can be assessed in terms of effectiveness and efficiency. As part of the alignment approaches, this study's focus was between strategy and processes of knowledge: further research could bring to light new alignment options of knowledge and the associated implications.Originality/valueThis study illustrates that organisations can improve the management of knowledge through alignment between KM strategies and KM processes. Such an improvement is also possible in the absence of a KM strategy emphasis, where alignment would require a deeper examination of workgroup knowledge processes. This study also identifies specific alignment enablers to align KM strategy and KM processes.
