Published: October 2009

Abstract
While interspecific variation in the temperature response of photosynthesis is well documented, the underlying physiological mechanisms remain unknown. Moreover, mechanisms related to species-dependent differences in photosynthetic temperature acclimation are unclear. We compared photosynthetic temperature acclimation in 11 crop species differing in their cold tolerance, which were grown at 15°C or 30°C. Cold-tolerant species exhibited a large decrease in optimum temperature for the photosynthetic rate at 360 μL L™1 CO2 concentration [Opt (A 360)] when growth temperature decreased from 30°C to 15°C, whereas cold-sensitive species were less plastic in Opt (A 360). Analysis using the C3 photosynthesis model shows that the limiting step of A 360 at the optimum temperature differed between cold-tolerant and cold-sensitive species; ribulose 1,5-bisphosphate carboxylation rate was limiting in cold-tolerant species, while ribulose 1,5-bisphosphate regeneration rate was limiting in cold-sensitive species. Alterations in parameters related to photosynthetic temperature acclimation, including the limiting step of A 360, leaf nitrogen, and Rubisco contents, were more plastic to growth temperature in cold-tolerant species than in cold-sensitive species. These plastic alterations contributed to the noted growth temperature-dependent changes in Opt (A 360) in cold-tolerant species. Consequently, cold-tolerant species were able to maintain high A 360 at 15°C or 30°C, whereas cold-sensitive species were not. We conclude that differences in the plasticity of photosynthetic parameters with respect to growth temperature were responsible for the noted interspecific differences in photosynthetic temperature acclimation between cold-tolerant and cold-sensitive species.

AbstractThe viral genome-linked protein, VPg, of potyviruses is a multifunctional protein involved in viral genome translation and replication. Previous studies have shown that both eukaryotic translation initiation factor 4E (eIF4E) and eIF4G or their respective isoforms from the eIF4F complex, which modulates the initiation of protein translation, selectively interact with VPg and are required for potyvirus infection. Here, we report the identification of two DEAD-box RNA helicase-like proteins, PpDDXL and AtRH8 from peach (Prunus persica) and Arabidopsis (Arabidopsis thaliana), respectively, both interacting with VPg. We show that AtRH8 is dispensable for plant growth and development but necessary for potyvirus infection. In potyvirus-infected Nicotiana benthamiana leaf tissues, AtRH8 colocalizes with the chloroplast-bound virus accumulation vesicles, suggesting a possible role of AtRH8 in viral genome translation and replication. Deletion analyses of AtRH8 have identified the VPg-binding region. Comparison of this region and the corresponding region of PpDDXL suggests that they are highly conserved and share the same secondary structure. Moreover, overexpression of the VPg-binding region from either AtRH8 or PpDDXL suppresses potyvirus accumulation in infected N. benthamiana leaf tissues. Taken together, these data demonstrate that AtRH8, interacting with VPg, is a host factor required for the potyvirus infection process and that both AtRH8 and PpDDXL may be manipulated for the development of genetic resistance against potyvirus infections.

Published: October 2009

AbstractThe main trimeric light-harvesting complex of higher plants (LHCII) consists of three different Lhcb proteins (Lhcb1-3). We show that Arabidopsis thaliana T-DNA knockout plants lacking Lhcb3 (koLhcb3) compensate for the lack of Lhcb3 by producing increased amounts of Lhcb1 and Lhcb2. As in wild-type plants, LHCII-photosystem II (PSII) supercomplexes were present in Lhcb3 knockout plants (koLhcb3), and preservation of the LHCII trimers (M trimers) indicates that the Lhcb3 in M trimers has been replaced by Lhcb1 and/or Lhcb2. However, the rotational position of the M LHCII trimer was altered, suggesting that the Lhcb3 subunit affects the macrostructural arrangement of the LHCII antenna. The absence of Lhcb3 did not result in any significant alteration in PSII efficiency or qE type of nonphotochemical quenching, but the rate of transition from State 1 to State 2 was increased in koLhcb3, although the final extent of state transition was unchanged. The level of phosphorylation of LHCII was increased in the koLhcb3 plants compared with wild-type plants in both State 1 and State 2. The relative increase in phosphorylation upon transition from State 1 to State 2 was also significantly higher in koLhcb3. It is suggested that the main function of Lhcb3 is to modulate the rate of state transitions.

Published: October 2009

AbstractLocal efflux-dependent auxin gradients and maxima mediate organ and tissue development in plants. Auxin efflux is regulated by dynamic expression and subcellular localization of the PIN auxin-efflux proteins, which appears to be established not only through a self-organizing auxin-mediated polarization mechanism, but also through other means, such as cell fate determination and auxin-independent mechanisms. Here, we show that the Arabidopsis thaliana NO VEIN (NOV) gene, encoding a novel, plant-specific nuclear factor, is required for leaf vascular development, cellular patterning and stem cell maintenance in the root meristem, as well as for cotyledon outgrowth and separation. nov mutations affect many aspects of auxin-dependent development without directly affecting auxin perception. NOV is required for provascular PIN1 expression and region-specific expression of PIN7 in leaf primordia, cell type–specific expression of PIN3, PIN4, and PIN7 in the root, and PIN2 polarity in the root cortex. NOV is specifically expressed in developing embryos, leaf primordia, and shoot and root apical meristems. Our data suggest that NOV function underlies cell fate decisions associated with auxin gradients and maxima, thus establishing cell type–specific PIN expression and polarity. We propose that NOV mediates the acquisition of competence to undergo auxin-dependent coordinated cell specification and patterning, thereby eliciting context-dependent auxin-mediated developmental responses.

Published: October 2009

PurposeThe purpose of this paper to standardize the technique for the development of potato flour and to incorporate it in development of the products along with defatted soy flour and maize flour. Also, effect of processing techniques like frying and fermentation on anti‐nutritional content of the products was studied.Design/methodology/approachThe ingredients as well as developed products were analyzed for the macronutrients, viz protein, ash and fat. Also anti‐nutrients like phytic acid, saponin, polyphenols and trypsin inhibitors were estimated by employing standard techniques. Data thus obtained were subjected to analysis of variance according to standard method of statistical analysis.FindingsPotato flour being a versatile ingredient can be easily incorporated in development of various products. Frying and fermentation resulted in decrease of anti‐nutritional factors.Originality/valueThese developed products could be instrumental in alleviating malnutrition as they have high nutritional value and are low in anti‐nutrients.
Market creation: the epitome of entrepreneurial marketing practices
Authors: Gaddefors Johan , Anderson Alistair R. 
Published: October 2009

PurposeThe purpose of this paper is to examine theories of marketing and entrepreneurship and compare these with entrepreneurial marketing practices.Design/methodology/approachThe paper uses a case study to explore the social constructions of narratives.FindingsThe paper reveals how interactions based around meanings, purpose and identities work to create products, customers, entrepreneurs and even the market. Here the emphasis on signs, symbols and images redirects attention to create space for expectations to grow.Research limitations/implicationsThe paper develops its argument that merely modifying existing theory is conceptually inadequate; a new framework is introduced which enables the understanding of how entrepreneurship and marketing combine. The paper shows how this fertile dynamic produces not only new products, but also may actually create new markets.Originality/valueThis case study demonstrates how entrepreneurship and marketing become inseparable in the co‐production of identity and future.
Mecca‐Cola: message in a bottle
Authors: Justo Rachida , Cruz Cristina 
Published: October 2009

PurposeThis paper aims to describe how Taoufik Mathlouthi created Mecca‐Cola, a beverage designed as an alternative to major American colas. It is intended to raise student's consciousness about the fact that good opportunities can be driven by political and social changes. Second, it aims to bring them the opportunity to reflect about their own definition of a social entrepreneur and understand the challenges behind pursuing multiple objectives that is, trying to blend and integrate non‐profit goals with rigorous venture development practices.Design/methodology/approachTo write this case, two complementary methodologies were relied on: interviews with founder and employees and use of secondary information such as press articles.FindingsThe case describes how what began as a venture for French Muslims, garnered international appeal, with markets opening up in 54 countries in less than two years. However, despite this success, the following stage of transforming Mecca‐Cola into a sustainable business while maintaining its “essence” was proving difficult for the company.Originality/valueThe case is intended for an undergraduate or MBA course in entrepreneurship. The innovative aspect is that the entrepreneur discovered a business opportunity that arose in the wake of the Iraq war in the form of discontent with US foreign policy among some sectors of the population. As courses on social entrepreneurship begin to emerge in academic institutions this case also offers an interesting example of the challenges brought about initiating this kind of business and achieving a double bottom line.
The Myers‐Briggs type indicator and transformational leadership
Authors: Brown F. William , Reilly Michael D. 
Published: October 2009

PurposeThis paper aims to study the possible relationship between elements of personality as measured by the Myers‐Briggs type indicator (MBTI) and transformational leadership (TL) as measured by the Multifactor Leadership Questionnaire (MLQ).Design/methodology/approachThe study was done at the North American manufacturing facility of an international technology company. Utilizing the Multifactor Leadership Questionnaire to measure transformational leadership, over 2,000 followers provided assessments of transformational leadership for 148 managers who had done self‐assessments and had completed Form K of the MBTI.FindingsNo relationship was found between follower assessments of transformational leadership and leader personality as measured by the MBTI. Leaders did, however, perceive themselves to be significantly more transformational than did those who reported to them. Leader preference for extraversion over introversion and intuition over perception were both significantly associated with self‐reports of transformational leadership.Research limitations/implicationsStudies utilizing large samples across a variety of organizational settings are needed to confirm the results of this study.Practical implicationsThis study calls into question the existence of a relationship between the MBTI and transformational leadership. The study does not provide any support for the possible utility of the MBTI for the prediction or explanation of transformational leadership behaviors. Assuming that followers' perceptions of TL are the more valid, the findings suggest that previous results linking MBTI and TL may be measurement artifacts.Originality/valueUtilizing a large sample, the MLQ and continuous measures of MBTI preferences the results of this study contradict previous reports of a relationship between personality as measured by the MBTI and transformational leadership.

This methodology is then tested in a case environment.FindingsThe findings suggest that the methodology and the experience sheet provide a usable and interesting way of assessing user experience in the workplace environment.Practical implicationsThis article offers an illustrative way to understand user experience in workplace environments, and through that helps in improving existing working environments and in creating new ones.Originality/valueThis article combines theoretical understanding in a cross‐disciplinary manner in a novel way, and through that introduces a usable method for workplace improvement for practitioners.
Customer acquisition costs: the costs of growing business in public libraries
Authors: Nash White Larry 
Published: October 2009

PurposeThe purpose of this paper is to examine the associated customer acquisition costs of public libraries. The intention of the paper is to develop awareness of the hidden costs associated with customer acquisition, and develop assessment tools or models to effectively manage the resources associated with customer acquisition to aid library administrators in strategic budgeting and planning.Design/methodology/approachThe paper is prepared through review of the library and business literature associated with customer acquisitions. No definitive data on customer turnover rates or models of assessing customer acquisitions cost are identified in the review of the literature.FindingsWhile not identified or managed systematically, the calculation of customer acquisition costs, customer turnover rates, and the effective management of associated customer acquisition cost is strategically imperative for public libraries. Public libraries generally do not track customer turnover or the associated costs of acquiring new or replacement customers that come about due to this turnover. There is not a definitive estimate of customer turnover in public libraries, so exact costs determination will vary by public library system. Public libraries can reduce their customer acquisition costs through the retention of current customers with high quality service and in effectively managing the customer acquisition process in the strategic budgeting and planning processes of the library.Originality/valueLibraries that can effectively acquire new or replacement customers and manage the costs of this process will more effectively utilize resources and maximize customer value for the library. This paper proposes several cost assessment calculations to help guide library administrators in making strategic decisions.

Authors: Grawe Scott J. 
Published: October 2009

PurposeThe purpose of this paper is to develop a model of logistics innovation based on previous studies in the logistics literature and recommend opportunities for further research.Design/methodology/approachA review of the following logistics journals is conducted: International Journal of Logistics Management, International Journal of Physical Distribution & Logistics Management, Journal of Business Logistics, Transportation Journal, and Transportation Research: Part E. Articles for the review are selected based on their explicit relevance to logistics innovation.FindingsThere has been a limited amount of theory‐based research conducted on the topic of logistics innovation. While antecedents and outcomes of logistics innovation have been identified within the leading logistics journals, very little empirical testing has been done. The diffusion of logistics innovations has also received attention in the logistics literature.Research limitations/implicationsThe scope of this paper is limited to top logistics journals. Further, theoretical development in the study of logistics innovation is warranted.Originality/valueFew studies have specifically addressed logistics innovation. The paper offers a model of logistics innovation based on a review of the existing literature.

A comparison of inter‐ and intra‐organizational relationships
Authors: Mena Carlos , Humphries Andrew , Wilding Richard 
Published: October 2009

PurposeTheoretical models of collaboration assume that intra‐organizational relationships are more collaborative that inter‐organizational ones. This paper seeks to question the validity of this assumption by comparing the levels of collaboration in two cases that comprise both types of relationship.Design/methodology/approachTwo case studies in the UK food industry were conducted, in each two relationships were analyzed: one inter‐ and one intra‐organizational. Data were collected through a questionnaire followed by semi‐structured interviews.FindingsThis exploratory research indicates that in both case studies intra‐organizational relationships have lower levels of collaboration than inter‐organizational ones. This appears to contradict the commonly held assumption that intra‐organizational relationships involve closer collaborations than inter‐organizational ones.Research limitations/implicationsCase study approaches have reliability and generalisability limitations, however, the paper was given in‐depth access to four relationships (two per case), which provide a basis for further research. The use of multiple informants and two methods of data collection helped to increase reliability and efforts were made to reduce bias in responses by ensuring confidentiality and engaging with participating companies in an impartial way.Practical implicationsA better appreciation of collaboration in inter‐ and intra‐ organizational relationships will result in managers making better decisions about how their organization relates internally and externally. This could have implications for decisions on make‐buy, alliances, and acquisitions.Originality/valueThe paper shows that it is possible to have relationships with customers and suppliers that are more collaborative than those between departments within a single organization. This finding appears to challenge traditional assumptions and provides a new perspective of the management of supply chain relationships.
Perspectives on organisational change
Authors: Silver Lars 
Published: October 2009

PurposeThe purpose of the paper is to investigate identity change in savings banks. The savings bank movement is gradually shifting from a residual culture of using the bank to promote savings, into a dominant culture closely resembling commercial banks.Design/methodology/approachTheory draws on key research in the field of organisational change and corporate identity. A qualitative methodology is used to investigate a large portion of the savings banks movement in Sweden.FindingsThe shift in culture is a result of decreasing values of original visions, a process of commercialising the savings bank idea and increasing chief executive officer (CEO) influence and professionalisation.Research limitations/implicationsThe results are primarily applicable for savings banks.Practical implicationsThe paper shows the ongoing changes in the savings bank community and the effects of these changes on critical stakeholders. In particular, the important role of CEOs in non‐profit organisations is illustrated and discussed.Originality/valueFew studies focus on change in culture and the consequences for stakeholder relations. There is no prior study on savings banks and organisational change.
