ABSTRACTDuring cytokinesis, fission yeast coordinates actomyosin ring constriction with septum ingression, resulting in concentric furrow formation. Mechanisms coordinating septum ingression with the actomyosin ring remain unclear. We report that cells lacking the Cdc42 activator Gef1, combined with an activated allele of the formin, Cdc12, display non-concentric furrowing. Although cells that furrow non-concentrically display normal actomyosin rings, the scaffold Cdc15 is unevenly distributed along the ring. This suggests that after ring assembly, uniform Cdc15 distribution along the ring drives proper furrow formation. We find that Cdc15 levels at the ring are reduced in the activatedcdc12mutant, or upon disruption of Arp2/3 complex-dependent endocytic patches. Furthermore, Cdc15 levels in endocytic patches increase ingef1mutants. We hypothesize that assembled rings recruit Cdc15 from endocytic patches. Patches with higher Cdc15 levels and slower ring-association rate lead to uneven Cdc15 distribution. Based on this hypothesis we developed a mathematical model that captures experimentally observed Cdc15 distributions along the ring. We propose that, at the ring, Gef1 and endocytic events promote uniform Cdc15 distribution to enable proper septum ingression and concentric furrow formation.Summary StatementGef1 and endocytic events at the assembled actomyosin ring facilitate uniform Cdc15 distribution along the ring thus enabling concentric furrow formation.
Cluster analysis for fruit consumption patterns: an international study
Authors: Heng Yan , House Lisa A. 
Published: July 2018

Purpose
The purpose of this paper is to investigate the fruit consumer segmentations and compare the consumption patterns across North America, Europe and East Asia. This study aims to identify the key drivers for fruit consumption across segments and regions, in terms of socioeconomics and shopping behavior.

Design/methodology/approach
An international survey to collect information on fruit consumption, demographics and lifestyle factors was developed. Respondents from eight countries across North America, Europe and East Asia were recruited from online panels. A total usable sample of 7,793 respondents was collected.

Findings
Respondents can be clustered in three segments: low-frequency consumer, common fruit consumer and high-frequency consumer. These consumer segments are heterogeneous in socioeconomics and shopping behavior across regions. Overall, the high-frequency consumer cluster had more individuals who were older, married, not single/never married, self-reported healthy and physically active. The low-frequency consumer group had a larger number of individuals who were younger, living alone, single/never married, self-reported unhealthy and not active. Moreover, the high-frequency fruit consumers tended to focus on many fruit attributes, such as freshness, nutritional value, origin and in the season, but not focus on the price.

Originality/value
This study uses a unique data set covering eight countries and provides a comprehensive comparison of international fruit consumption patterns and identifying the important factors driving fruit purchase decisions.
Strategising stakeholder empowerment for effective co-management within fishery-based commons
Authors: Freeman Edward Robert , Civera Chiara , Cortese Damiano , Fiandrino Simona 
Published: July 2018

Purpose
The purpose of this paper is to link empowerment to the engagement of low-power stakeholders in the context of marine protected areas (MPAs) to suggest how empowerment-based engagement can be strategised to prevent and overcome management crises within a natural common good and ultimately achieve effective co-management.

Design/methodology/approach
This research employs a longitudinal case study methodology. The subject of the study is Torre Guaceto MPA, a natural common good, internationally recognised as a best practice of co-management.

Findings
The case study illustrates specific empowerment areas and actions that help move low-power stakeholders to higher levels of engagement to achieve effective co-management. It also suggests that the main strategic implication of empowerment-based engagement is the creation of empowered stakeholders who can serve as catalysts for sustaining the common through the development of entrepreneurial skills that satisfy joint interests.

Research limitations/implications
The applied methodology of a single case and the peculiar conditions intrinsic to this case can be overcome via the inclusion and comparison of other similar commons.

Practical implications
The study provides a stakeholder management model of empowerment-based engagement that offers concrete evidence of empowerment strategies that can be adopted and adapted by the management of similar natural common goods.

Originality/value
The research fills the literature gaps related to understanding the antecedents of engagement and its strategic implications within natural common pool resources.
Olive oil consumption: a preliminary study on Brazilian consumers
Authors: Antonialli Fabio , Mesquita Daniel Leite , Valadares Gustavo Clemente , de Rezende Daniel Carvalho , de Oliveira Adelson Francisco 
Published: July 2018

Purpose
The purpose of this paper is to propose an initial step for understanding the sensory perception and purchase intent of Brazilian olive oil consumers. It also investigates the sensory perception and purchase intent for a Brazilian-made olive oil.

Design/methodology/approach
The sample, consisting of 115 surveyed consumers, is described demographically. The aspects related to sensory analysis and purchase intent associated with the key attributes indicated by the consumers are then discussed. Finally, consumer segmentation is carried out to characterize the consumers in more detail, in terms of both demographic and predictive variables for olive oil consumption.

Findings
Consumers displayed a sensory perception that is coherent with olive oil characteristics, thus being able to distinguish three different olive oils from a compound oil sample. Regarding purchase intent and preference, consumers showed mixed behaviors, which was not entirely convergent with the identified sensory aspects. Therefore, it was possible to segment them into three distinct groups: utilitarian, naïve, and expert consumers.

Originality/value
Brazil is an emergent olive oil market, which can create both research and business opportunities for the country. This preliminary study contributes to the advancement of this research subject in the non-traditional markets for olive oil.
Exploring farmers markets as a temporary cluster to improve local food economy
Authors: Kassai Mahsa , Kaspar Jacob , Deif Ahmed , Smith Heather 
Published: July 2018

PurposeThe purpose of this paper is to explore how to improve the contribution of farmers markets (FMs) to the local food economy and improve their management through a new temporary clustering management approach.Design/methodology/approachThe research encompasses 78 structured interviews with farmers’ market vendors in the central coast region of California. A descriptive statistical and exploratory analysis to capture and evaluate the extent of various clustering activities currently existing in FMs is presented.FindingsAnalysis suggested an existing clustering behavior in FMs with different degrees that would enhance the role of these markets in local food economy. The improved social capital and financial performance of these markets shown in this study outperformed other cluster metrics monitored. Furthermore, there were some positive relationships between knowledge sharing (as a cluster activity) and both integration and financial activities among FMs vendors, highlighting interesting dynamics generated by the temporary nature of these clusters.Research limitations/implicationsThe study was based on an exploratory research design, investigating a selected number of vendors in the central coast region of California. The research does not claim to provide a comprehensive survey of all FMs.Practical implicationsThe analysis resulted in recommendations to improve efficiency of FMs’ practices at both the management level and the strategic level. These recommendations will enhance the contribution of these markets to the local food economy. The results also expand the practical knowledge bodies of regional and local food business development. Finally, the study highlights the social role of FMs through showing social capital as one of the main clustering drivers.Originality/valueThis study contributes to theoretical knowledge concerning the impact of clusters on operation performance by exploring a new temporary proximity that can be added to the existing geographical and digital proximity enriching the clustering approaches debate. Furthermore, the analysis provides specific novel insights into potential operational improvements for current farmers’ market management to enhance their economic and social roles.
Market power in food supply chain: evidence from Italian pasta chain
Authors: Cacchiarelli Luca , Sorrentino Alessandro 
Published: July 2018

Purpose
During the last years, the Italian pasta chain has been strongly affected by some events such as CAP reforms in the durum wheat sector that have progressively reduced government intervention in the market and a case of anti-competitive practices against pasta makers was identified and sanctioned by the Italian Antitrust Authority. The purpose of this paper is to detect the presence of market power in the different phases of the Italian pasta supply chain.

Design/methodology/approach
The authors applied the “first-pass” test proposed by Lloyd et al. (2009) on a set of monthly price indexes series from 2000 to 2013 in order to estimate if market power exists along Italian pasta chain.

Findings
Estimated results suggest that market power exists in the Italian pasta supply chain. Precisely, the presence of market power is detected for semolina producers in 2000–2004, for pasta makers in 2005–2008 as already identified by Italian antitrust and, finally, for retailers in 2008–2013.

Research limitations/implications
The method is a “first pass” test that only allows researchers to identify the presence of market power, but it is unable to estimate the intensity of this power.

Originality/value
The paper gives a contribute on estimation of market power in a food supply chain affected by CAP reform and antitrust intervention.
Vulnerability to food insecurity in rural Punjab, Pakistan
Authors: Bashir Muhammad Khalid , Schilizzi Steven , Sadler Rohan , Ali Ghaffar 
Published: July 2018

Purpose
The purpose of this paper is to measure the vulnerability to food insecurity in rural Punjab, Pakistan.

Design/methodology/approach
Primary data of 1,152 households were collected. The extent of food deficiency was measured using dietary intake assessment method (seven days). Value at Risk (VaR) and conditional Value at Risk (cVaR), a method widely used for risk analysis in financial institutes, were applied to assess the vulnerability to food insecurity.

Findings
In total, 23 percent of the sample households were measured as food deficient. The VaR and cVaR results identified that the lowest 3 percentiles (up to 30 percent) were at risk to become food deficient without any seasonal shortages. In case of shocks, up till sixth percentiles (60 percent) will be as at risk of food deficiency. This study suggests that multi-period data, at least quarterly, are required to predict vulnerability. It is suggested that a blanket policy is not a good approach. Once the most vulnerable households are identified, a targeted approach must be opted.

Originality/value
Generalizing the results of one week’s calorie calculations may produce biased results that may mislead the policy process. A multi-period data collection is costly and cumbersome. The application of VaR and cVaR helps overcome this issue. Furthermore, this is one of the initial studies to apply these methods to food security analysis.
Prioritization of drivers, enablers and resistors of agri-logistics in an emerging economy using fuzzy AHP
Authors: Jakhar Meenakshi , Srivastava Manoj Kumar 
Published: July 2018

Purpose
The purpose of this paper is to identify and prioritize the drivers, enablers and resistors of agri-logistics improvements in an emerging economy like India. The field of agri-logistics lies at the critical intersection of the agricultural and logistics sectors and is capable of ameliorating the state of food distribution in the country. The inefficiencies inherent in the food distribution system in India lead to massive post-harvest wastage that is estimated at around 13bn dollars per annum. This paper examines the improvement drivers, enablers and resistors of agri-logistics that can significantly contribute toward the enhancement of the agricultural supply chain.

Design/methodology/approach
The synthesis and prioritization of drivers, enablers and resistors was based on an extensive literature review and consultation with experts. With the help of semi-structured interviews and a fuzzy analytic hierarchy process approach, the research develops a drivers-enablers-resitors framework.

Findings
The outcome is a hierarchy-based framework that prioritizes the drivers, enablers and resistors of agri-logistics. The research reveals the critical areas where decision makers should channelize their resources and efforts to gain maximum benefits.

Originality/value
The segmentation of the factors impacting agri-logistics into drivers, enablers and resistors provides a fresh perspective on the issue and helps improve understanding of the problem. Prioritization of the factors represents a unique contribution to the field of agri-logistics.
Comparing German and Italian food banks
Authors: Rombach Meike , Bitsch Vera , Kang Eunkyung , Ricchieri Francesco 
Published: July 2018

Purpose
The purpose of this paper is to investigate food bank actors’ knowledge of food insecurity in Germany and in Italy, as well as interactions between food bank actors and food bank users. The study builds on a knowledge framework from an educational context and applies it to food banks.

Design/methodology/approach
The study uses a qualitative research approach. In all, 22 in-depth interviews were recorded, transcribed and analyzed through inductive qualitative content analysis.

Findings
German and Italian food bank actors interviewed had at least situational knowledge on food insecurity. Some actors of the Italian food bank also showed procedural knowledge. Interactions between food bank personnel and users were affected by feelings of gratitude, shame, anger and disappointment.

Originality/value
The study explores food bank personnel’s knowledge on food insecurity, which appears to be a knowledge gap, even though many prior studies were dedicated to food banks and food insecurity. The study contributes to knowledge systematization to provide best practice recommendations for volunteer-user interaction, and suggests how food bank managers and volunteers’ knowledge can be improved.
Economic sustainability of buildings
Authors: Ribas Domingos António , Cachim Paulo 
Published: July 2018

Purpose
The purpose of this paper is to present an innovative approach for the development of a methodology to systematically assess the economic performance and for the assessment of the economic sustainability of a building, through the calculation of an economic sustainability index, within the sustainability framework according to the rules defined in EN 16627.

Design/methodology/approach
The methodology follows the principle of modularity, where aspects and impacts that influence the economic performance of the building during the phases of its life cycle are assigned to levels. It presents a model based on the construction costs of the building. The methodology in centered in the before use phase and restricted to residential buildings.

Findings
Definition of a model for assessing the economic performance and calculation of an economic sustainability index.

Research limitations/implications
The methodology is focused only in the before use phase of the buildings, assuming they have the same functional equivalent. It can be expanded to include the other phases of the building life cycle.

Practical implications
The developed methodology will allow the selection of construction procedures, based on economic sustainability, contributing to more rational and support decisions.

Social implications
Contributing to a more sustainable society.

Originality/value
The European framework of EN 15643 and EN 16627 for the assessment of building sustainability is new and, as such, not implemented in most practical tools. Also, economic sustainability is not usually considered in detail in existing models. This paper presents a methodology following the framework and, simultaneously, possible to integrate in existing approaches.
Revisiting storey enclosure method for early estimation of structural building construction cost
Authors: Dang Chau Ngoc , Le-Hoai Long 
Published: July 2018

Purpose
The purpose of this paper is to develop several predictive models for estimating the structural construction cost and establish range estimation for the structural construction cost using design information available in early stages of residential building projects.

Design/methodology/approach
Information about residential building projects is collected based on project documents from construction companies with regard to the design parameters and the actual structural construction costs at completion. Storey enclosure method (SEM) is fundamental for determining the building design parameters, forming the potential variables and developing the cost estimation models using regression analysis. Nonparametric bootstrap method is used to establish range estimation for the structural construction cost.

Findings
A model which is developed from an integration of advanced SEM, principle component analysis and regression analysis is robust in terms of predictability. In terms of range estimation, cumulative probability-based range estimates and confidence intervals are established. While cumulative probability-based range estimates provide information about the level of uncertainty included in the estimate, confidence intervals provide information about the variability of the estimate. Such information could be very crucial for management decisions in early stages of residential building projects.

Originality/value
This study could provide practitioners with a better understanding of the uncertainty and variability included in the cost estimate. Hence, they could make effective improvements on cost-related management approaches to enhance project cost performance.
The role of formal and informal mechanisms in implementing lean principles in construction projects
Authors: Bygballe Lena Elisabeth , Endresen Maria , Fålun Silje 
Published: July 2018

Purpose
Previous research shows that implementing lean construction is not a straightforward task. The purpose of this paper is to examine the role of formal and informal mechanisms in implementing lean principles in construction projects.

Design/methodology/approach
The paper draws on a single case study of the implementation of innovative lean principles in a public construction project in Norway. The study is based on qualitative data, including 17 semi-structured interviews with 21 individuals, document analysis, and observations in meetings and seminars, in addition to informal conversations.

Findings
Formal mechanisms, including contractual arrangements, have the potential to both facilitate and hamper the implementation of innovative lean principles in a construction project. They might create coherence, but at the same time they might limit the scope of the concept in such a way that others do not accept it. Informal mechanisms, including social and lateral relationships and trust aid implementation, both directly by creating commitment and by modifying the challenges that the formal mechanisms potentially incur. Formal mechanisms may, in turn, nurture the informal ones.

Research limitations/implications
The research is based on a single case study within the Norwegian public sector, which is dependent on specific public procurement regulations and subject to strong contractual traditions.

Originality/value
The research extends the existing knowledge of implementation of lean construction in the construction industry. It helps refining the understanding of the role played by formal and informal mechanisms, and the interplay between them in the implementation process. This knowledge is also relevant for process innovations in construction in general.
International comparisons of nominal and real construction labour productivity
Authors: Chia Fah Choy , Skitmore Martin , Gray Jason , Bridge Adrian 
Published: July 2018

PurposeA comparison of international construction labour productivity (CLP) is carried out by the conventional use of exchange rates to convert national construction output to a common base currency. Such measurement is always distorted by price-level differences between countries and therefore the purpose of this paper is to adopt a purchasing power parities (PPPs) approach, which eliminates price-level differences, as an alternative means of comparing CLP.Design/methodology/approachPPP construction expenditure data from the World Bank’s International Comparison Programme 2011 and employment statistics maintained by the International Labour Organization are used to generate the CLP of 93 matching economies. A one-way analysis of variance is conducted to evaluate the relationship between the development status and the CLPs.FindingsThe CLPs of developed economies are higher than developing economies in both PPPs (real) and exchange rate (nominal) measurements. The real CLPs are always higher than nominal CLP in high-income, upper-middle-income, lower-middle-income and low-income economies. Both real and nominal CLPs converge along with the economic growth.Research limitations/implicationsThe average figures used in the study may not always be the most representative statistics. The CLPs determined provide an initial approximation for comparison between different economies to gain further insights into the best practices and policies for the more successful economies. Future research is recommended to uncover the underlying factors of CLPs congruence.Originality/valueThe convergence of real and nominal CLPs when economies transit from a developing to developed status indicates that the construction product has transformed from a commonly understood non-internationally traded product to an internationally traded product.
