Abstract
The Chlamydomonas reinhardtii proton gradient regulation5 (Crpgr5) mutant shows phenotypic and functional traits similar to mutants in the Arabidopsis (Arabidopsis thaliana) ortholog, Atpgr5, providing strong evidence for conservation of PGR5-mediated cyclic electron flow (CEF). Comparing the Crpgr5 mutant with the wild type, we discriminate two pathways for CEF and determine their maximum electron flow rates. The PGR5/proton gradient regulation-like1 (PGRL1) ferredoxin (Fd) pathway, involved in recycling excess reductant to increase ATP synthesis, may be controlled by extreme photosystem I acceptor side limitation or ATP depletion. Here, we show that PGR5/PGRL1-Fd CEF functions in accordance with an ATP/redox control model. In the absence of Rubisco and PGR5, a sustained electron flow is maintained with molecular oxygen instead of carbon dioxide serving as the terminal electron acceptor. When photosynthetic control is decreased, compensatory alternative pathways can take the full load of linear electron flow. In the case of the ATP synthase pgr5 double mutant, a decrease in photosensitivity is observed compared with the single ATPase-less mutant that we assign to a decreased proton motive force. Altogether, our results suggest that PGR5/PGRL1-Fd CEF is most required under conditions when Fd becomes overreduced and photosystem I is subjected to photoinhibition. CEF is not a valve; it only recycles electrons, but in doing so, it generates a proton motive force that controls the rate of photosynthesis. The conditions where the PGR5 pathway is most required may vary in photosynthetic organisms like C. reinhardtii from anoxia to high light to limitations imposed at the level of carbon dioxide fixation.
The mediating role of LMX between abusive supervision and work behaviors
Authors: Decoster Stijn , Camps Jeroen , Stouten Jeroen 
Published: March 2014

Purpose
– In a replication of a multi-source study by Xu et al., the authors examined whether leader-member exchange (LMX) mediates the relationship between abusive supervision and employee work behaviors, more specifically task performance, organizational citizenship behaviors toward the organization (OCBO), and toward other individuals (OCBI). Moreover, the authors also examined whether LMX mediates this relationship when the authors focus on the two dimensions of abusive supervision, that is active-aggressive and passive-aggressive abusive supervision.

Design/methodology/approach
– The authors collected multi-source data in order to minimize common method bias. The authors conducted regression analyses, Sobel tests, and bootstrapping techniques.

Findings
– The authors found support that LMX mediates the negative relationship between abusive supervision and OCBO and OCBI. However, the authors could not replicate the mediating role of LMX in the association between abusive supervision and employees' performance. Similar results were obtained when the data were analyzed with the active-aggressive and passive-aggressive abusive supervision subscales.

Research limitations/implications
– Due to the cross-sectional nature of the study, this study does not allow the authors to draw causal conclusions regarding the proposed relationships.

Originality/value
– The authors replicated Xu et al.'s findings in a European context with a different sample and different measures for LMX, performance, and OCBI. The authors conducted bootstrapping analyses in order to control for the skewed distribution of abusive supervision. The authors explore whether the proposed relations still stand with regard to active-aggressive and passive-aggressive abusive supervision.
Procurement and consumption of local and organic food in the catering of a rural town
Authors: Tikkanen Irma 
Published: March 2014

Purpose
– This paper aims to describe the transformation towards consuming local and organic food (LOF) in the catering of a rural town. Product development cooperation, procurement, consumption, and prices are illustrated. Achieved local, social and environmental benefits are depicted.

Design/methodology/approach
– Theoretical framework includes the EU's strategy for corporate social responsibility concerning public procurement. Recent research on LOF and its procurement are summarized. The sources for empirical data included web pages depicting the case town and an interviewee, namely the food service manager.

Findings
– The results indicated that in 2011 local food products amounted to 46 per cent, whereas organic food products accounted for 14 per cent of the food procurement in the case town school's catering. The percentage of local food products in the whole town's catering amounted to 13. Benefits for the local community included money supporting the local economy, which thus facilitated the producers developing their businesses. However, higher prices were paid. Social benefits entailed that LOF contains the least amount of additives possible and LOF also advocates local food culture. Environmental benefits included, e.g. the following aspects: protecting the natural environment; decreasing packaging and bio waste; and diminished consuming water and energy.

Practical implications
– Increasing consumption of LOF required the following actions: integrating LOF into the town's strategy; allocating extra resources; training catering personnel; developing products with producers; and organising local procurement procedures.

Originality/value
– The results offer ideas for small municipalities how to increase the consumption of LOF gradually, and thus achieve benefits for the local community. The results may interest also those selling-in to that market sector.
Consumers' behaviors when eating out
Authors: Choi Jinkyung , Zhao Jinlin 
Published: March 2014

Purpose
– The present study aimed to discover whether there are any differences among people in healthy eating and nutrition consciousness when they eat out at restaurants. Also, the study aimed to determine what relationship exists between consumers' lifestyle and their behavioral intention to eat healthily when dining out. In addition, the study investigated the relationships between restaurant attributes and consumers' intention to eat healthily when dining out.

Design/methodology/approach
– This study posits that restaurant attributes have an impact on consumers' intention to order healthy meals at a restaurant. Questionnaires were distributed and collected over a two-month period in south Florida. Respondents were asked to indicate on a five-point scale their considerations when selecting a restaurant and particular ingredients in the food when dining out. The study analyzed the data using one-way ANOVA and Games-Howell test in order to find that considerations about nutritional components when choosing a meal at a restaurant. Also, multiple regression was run to determine the relationship between lifestyle and restaurant attributes and intention to order healthy food at a restaurant.

Findings
– Most of the respondents (76.5 percent) were concerned about their weight; however, only 26.7 percent of the respondents were actually on a diet. Of the respondents 33 percent knew about MyPyramid (USDA), which is an updated version of the Food Pyramid (USDA). Based on the results of one-way ANOVA and Games-Howell test, the study found that considerations about nutritional components when choosing a meal at a restaurant differed according to consumers' knowledge of health issues, weight concerns, gender, age, and marital status. Also, the results of multiple regression suggested that lifestyle, offering variety of healthy food, and services were significant predictors of consumers' intention to order healthy food at a restaurant, whereas other attributes of restaurants were not significant predictors for the ordering of healthy food.

Originality/value
– This study has contributed unique and extended conclusions from previous studies and has given consumers a better understanding about particular nutritional components in order for them to take advantage of the recent trend in more healthy foods being available at restaurants. The results of this study revealed that restaurants' marketing strategies for healthy food need to target consumers whose lifestyle promotes a healthy life in terms of regular exercise, dietary plans, or eating food considering the FoodPyramid, rather than target consumers whose lifestyle is less healthy. However, the results of this study also suggest that the offering of healthy food and good services do have effect on consumers' consideration to order healthy food.
Expected and experienced quality as predictors of intention to purchase four new processed beef products
Authors: Saeed Faiza , G. Grunert Klaus 
Published: March 2014

Purpose
– This paper aims to explore consumers' perception of quality of new processed beef products and the role of expected and experienced quality in the formation of consumer's purchase intentions. Based on the Total Food Quality Model, a conceptual framework is developed that relates cue evaluation, expected quality, experienced quality, purchase motive fulfilment and purchase intention.

Design/methodology/approach
– Structural equation modeling is used to test the framework with data from a sample of 201 respondents, involving three steps. First, principal component analyses were applied to explore underlying factor structures within each construct. Based on the exploratory factor analyses, measurement models were estimated, with the measured variables as indicators of latent constructs for all the four products. Finally, structural models were estimated for the relationships among the latent constructs.

Findings
– Results show that cue evaluations, expected/experienced quality and purchase motive fulfilment are all predictors of purchase intention, but that their weight and causal structure differ between purchase intentions before and after trial.

Practical implications
– Implications for the introduction of new beef products are discussed.

Originality/value
– This paper is an attempt to quantitatively estimate the relationships between quality cues, expected and experienced quality, and purchase motives as determinants of purchase intention for new products using structural equation modeling.
Enhancing the impact of online simulations through blended learning
Authors: Lean Jonathan , Moizer Jonathan , Newbery Robert 
Published: March 2014

Purpose– The purpose of this paper is to describe an approach for utilising a critical incident method within the context of an online business simulation game in order to provide an effective framework for reflective learning.Design/methodology/approach– The paper presents a review of pertinent literature to place the critical incident technique within the novel context of simulation gaming. Through presenting a case study of practice, it goes on to describe a blended learning approach that combines online simulation with post-simulation reflection based on the critical incident method. An action research approach is adopted as a framework for reflection on practice.Findings– From a conceptual perspective, there are a number of potential benefits to employing a critical incident approach combined with simulation gaming. The ability of educators to compress time frames and manage the introduction of critical incidents allows students to learn in a way that would not be possible in the real world. Furthermore, carefully designed post-simulation debriefing, structured around a critical incident framework, has the potential to enhance the learning impact of online simulation.Research limitations/implications– The research is limited in that a single case study context is described. Further evaluation research is required to fully assess the benefits of the approach adopted.Originality/value– The study explores the use of the critical incident approach within the novel context of online simulation gaming. It provides educators with a blended learning method that can be employed to enhance the impact of e-learning through structured reflection.
Borrower attitudes, lender attitudes and agricultural lending in rural China
Authors: Kong Rong , Turvey Calum , Xu Xiaolan , Liu Fei 
Published: March 2014

Purpose
– The purpose of this paper is to investigate the lender-borrower relationship as it relates to Sannong loans for agricultural and rural financial markets by Rural Credit Cooperatives (RCCs) and other rural lenders. This paper is motivated by recent reforms to the rural credit market designed to encourage increased lending, particularly to farmers. Little is understood about the lender-borrower relationship in rural China. This paper fills that gap.

Design/methodology/approach
– The paper investigates relational attitudes between 120 loan officers at RCCs in China's costal Shandong province, paired with a field survey using matched questions to 394 farm households in the same region. Pairing lenders’ perception toward borrowers regarding RCC microcredit lending mechanism, against borrowers’ perception toward lenders and how themselves were perceived by lenders in the same regards, the paper investigates the degree of disconnect between lenders and with distinct cluster groupings based on their perceptions, the paper analyzes the influence of demographics on the borrower and lender cluster memberships.

Findings
– The paper identifies four borrower clusters and two lender clusters. Borrower clusters are segmented on credit access and satisfaction with their rural lender. The paper also identifies two lender clusters, segmented principally on financial incentives and lending activities. While all lenders view farming with higher regard than farmers believe they do, one cluster is clearly pro-farmer while the second is somewhat indifferent. Indifference is more related to current portfolio activities. The paper draws conclusions that policy initiatives should be put in place at RCCs that close the gap between lender and borrower in their credit relationship. Rural lenders should concentrate on advocating RCCs’ care and trust toward agriculture and farm households. At the institutional level, effort should be extended to train a dedicated team of loan officers that specialize in servicing farm households with standardized lending practices. This research provides financial institutions with outreach mechanisms to borrowers, while also training lenders to borrowers’ sensitivities.

Originality/value
– Management studies of RCCs are few. This is the first paper that the authors are aware of that studies farmer and lender attitudes on the same scale.
Assessing risk response maturity
Authors: Hashim Motaleb Omayma , Kishk Mohammed 
Published: March 2014

Purpose
– The aim of the research work that underpins this paper is, therefore, to examine the effectiveness of project management maturity in mitigation measures for risk response within construction companies to influence project success.

Design/methodology/approach
– Ninety-three questionnaires were collected from respondents in different construction companies in the UAE, in order to assess project maturity in construction projects. Fifteen key success factors emerged from the literature and the questionnaire survey as being susceptible to improvement with increasing the project success.

Findings
– The results reveal that maturity can be improved by developing mitigation measures which positively influence risk response for project success. Based on these results, a framework is proposed to improve the practical functioning of risk response.

Research limitations/implications
– This study, however, reflects the general view but for greater confirmation, in-depth investigation is required, and the suggestion is that more primary data should be gathered by the survey method in other project organisations that have adopted risk management maturity, in order to validate the preliminary findings in this paper. This research is being carried out and will be reported in a future paper.

Originality/value
– This framework provides a better risk response to achieve a higher level of maturity. One of the unique features of the study is the creation of new knowledge by focusing on the UAE. At the same time, the use of maturity modelling to handle construction delays risks provides new knowledge for a wider audience.
An empirically verified project risk maturity model
Authors: Hartono Budi , F.N. Wijaya Deo , M. Arini Hilya 
Published: March 2014

Purpose
– The purpose of this paper is to develop and to empirically verify a model of project risk management maturity (PRMM).

Design/methodology/approach
– Theoretical work to develop the initial model of risk maturity. Empirical study by a cross-sectional survey to the Indonesian construction industry.

Findings
– A new model of PRMM is developed and empirically tested. The model is valid (face validity, content validity, discriminant validity, convergent validity, and criterion validity) and reliable.

Research limitations/implications
– A more comprehensive, follow-up study is required to gain more insights on the actual maturity level of Indonesian construction industry.

Practical implications
– The model is applicable to assess the organizational maturity level which in turn could be used for improving organization performance.

Originality/value
– The work demonstrates a novel approach in developing models by emphasizing on the empirical verification.
If maturity is the answer, then exactly what was the question?
Authors: Mullaly Mark 
Published: March 2014

Purpose
– Maturity models have been widely adopted as a popular framework for improvement project management practices. Despite their prevalence, there is still minimal evidence that improvements in maturity correspond to improvements in performance or value. This paper aims to explore the challenges faced in applying project management maturity models and offers suggestions for their revision.

Design/methodology/approach
– The paper highlights the presumptions in their development and use that are inhibiting relevance of maturity models. Case studies from a major research project explore the relationship between maturity and value. Insights are generated on how project management maturity models need to change in order to become relevant.

Findings
– Project management maturity models presume that project management is universal, control oriented and consistent, and that maturity is a linear process. Empirical evidence demonstrates that the practice of project management varies, that different practices result in different value. The paper suggests that a contingent and contextual approach to assessment is required, which maturity models as currently defined may not be able to support.

Research limitations/implications
– This is a largely conceptual paper and draws on a limited number of case studies that derived maturity from a comprehensive understanding of project management practices. It is not tied to one specific model, and a model that would address the criticisms discussed here has not been conceived or developed.

Practical implications
– This paper will have particular relevance for organizations, who may place excess faith in the rhetoric surrounding maturity models without questioning their underlying relevance or value. It is also of importance to those who develop maturity models and suggests strategies for their significant revision.

Originality/value
– This paper takes an important look at whether maturity models actually deliver on their promise and argues that by both design and structure, they are unlikely to do so in their current form.
Emotional intelligence and leadership
Authors: McCleskey Jim 
Published: March 2014

Purpose
– In 1990, Salovey and Mayer presented a framework for emotional intelligence (EI). This marked the beginning of 20 years of academic research, development, and debate on the subject of EI. A significant amount of previous research has attempted to draw out the relationship between EI and leadership performance. EI has been a uniquely controversial area of the social sciences. EI is based on three simple yet fundamental premises. This manuscript reviews the definitions and models in the field of EI with special emphasis on the Mayer ability model and the connection between EI and leadership. The paper aims to discuss these issues.

Design/methodology/approach
– This paper takes the form of a literature review.

Findings
– EI appears to have a foothold in both our popular vernacular and our academic lexicon. However, it is not entirely clear what future form it will take.

Originality/value
– This manuscript explores the current relationship between EI and leadership, discusses the various instruments and scales used to measure the construct, and examines the controversy and criticism surrounding EI. Finally, it illuminates some areas for additional research.
