Influence of consumer regiocentrism on perceived value of wine
Authors: Pestar Bizjak Sandra , Hristov Hristo , Košmerl Tatjana , Kuhar Ales 
Published: November 2017

Purpose
The purpose of this paper is to identify which dimensions of perceived value of wine dominate in the perception of wine consumers from two distinctive wine producing regions and to examine how their respective regional identity, consumer regiocentrism (CR) and perceived value of wine are inter-related in determining consumers’ preference of wine.

Design/methodology/approach
A sample of 221 wine consumers from two Slovenian wine regions with contrasting wine-related and social specificities responded to an online questionnaire. Besides the wine-related consumer behaviour variables, the questionnaire contained CR, regional identity and consumer perceived value measurements, based on adapted CETSCALE, regional identity and PERVAL scales. The scales were validated, and structural equation modelling was used to evaluate the relationships between the constructs.

Findings
Perceived value of wine was found to consist of three dimensions: emotional-social, quality-price and terroir, which differ from those previously observed among wine consumers from the USA. Regional identity was found to be a direct antecedent of CR, and CR directly affects all three dimensions of perceived value of wine; these findings were evident in the original model and in both studied wine regions.

Research limitations/implications
Future research should extend the model to include other possible antecedents of CR and study its effects on different consequences, especially purchasing intent. Future studies would benefit by adding more indicators into scales to measure CR and regional identity to improve the model fit.

Originality/value
This study contributes to a better understanding of perceived value of wine and extends the current knowledge of how social and psychological phenomena interact when evaluating wine. The results herein should enable marketers to develop more sophisticated positioning strategies and support their decision making for an appropriate market approach.
Investment behavior of Canada egg producers
Authors: Tamini Lota D. , Doyon Maurice , Zan Micheline M. 
Published: November 2017

Purpose
The purpose of this paper is to document the level of risk in the Québec egg sector (conventional and specialty eggs) and analyze the optimal choices of Québec egg producers that must allocate limited resources to production of different types of eggs.

Design/methodology/approach
A quadratic programming approach applied to expected mean-variance models is used to analyze the impact of risk on decision to invest when the resources must be allocated to different type of production that have different risk levels. The model is calibrated using monthly data from 2009 to 2016.

Findings
Results indicated multiple uncertainty sources (technological, cost of production, price of eggs) that vary according to the types of eggs. Given risk aversion parameters, producer would favor production modes with the lowest producers’ price variance, which correspond to free-run eggs. Results also indicated that in response to a greater intensity of risk aversion, the course of action producers may choose is to increase the relative production of free-run eggs.

Research limitations/implications
The empirical limits of this research are found in the lack of quality data on producer prices and costs for specialty eggs. Future research could explore the relationship between the growing impact of egg for processing, which price is based on the US price, and its relationship with specialty eggs.

Practical implications
The findings of the study will be useful for policy makers and managers of eggs supply chain. This is important, given the recent announcement by Canadian’s large retailers and fast food companies to increase cage free eggs offering and, in some cases, eventually only selling these types of eggs.

Originality/value
This study adds to the understanding of the role of risk and uncertainty in the investment decision of egg producers and different mode of production, as well as in the development of the growing production of specialty eggs in Canada. It fills a gap in the literature regarding the impact of risk in Canadian egg production. This gap is likely explained by the perception of a lack of risk in this supply managed sector in Canada and its small size relative to other supply managed sector.
Codezin: braving the startup storm
Authors: Pal Shounak , Gupta Gaurav , Biswas Indranil 
Published: November 2017

Subject area
Entrepreneurship, Strategic management, Management information systems.

Study level/applicability
Undergraduate and graduate capstone course in entrepreneurship, strategic management or management information systems courses.

Case overview
This case study of a young technology firm, Codezin Technology Solutions, helps to analyze the challenges faced by such firms in emerging markets. Such markets are characterized by rapid turbulence in the market characteristics. The authors seek to analyze the role of disruptive regulatory changes, resulting in the growth of new startups, in affecting the growth and expansion of such young firms. Codezin was established in 2009 as a bootstrap company, to provide low-cost IT services to Indian small and medium scale enterprises (SMEs). Despite some initial success, it began to run into losses due to poor coordination and improper planning. After a period of struggle, the company stabilized its revenue from services business and expanded to mobile solutions, digital marketing, etc. But then the government of India announced the Startup India initiative at the beginning of 2016 to boost new ventures. Codezin did not qualify as per the government rules and thus failed to use the various incentives offered. Hence, it needs to determine a new strategy to compete with the onslaught of freshly funded startups but with a relative lack of market experience.

Expected learning outcomes
With the case discussion, the students will gain rich insights on technology businesses aimed at SMEs and the impact of changes in the regulatory regime in emerging markets like India. Further, they get to step into the shoes of the co-founders and choose between diversification vs new market development strategies, spurred by market disturbances and thinning competitive advantage.

Multidimensional study of hospitality and the host-guest paradigm in China
Authors: Chen Xiaoqing 
Published: November 2017

Purpose
This paper aims to analyse the conceptual bases of the related terms of “host” and “guest” in Chinese and reveal essential, though overlooked, cultural differences that relate to “hospitality” in Western and Chinese cultural contexts.

Design/methodology/approach
A presupposition of this conceptual investigation is that culture manifests itself linguistically. The analytic approach used here is textual analysis. Confucian classical texts are the main source of evidence for examining the conceptual commitments of the Chinese characters 主 and 客 and their corresponding practical expressions.

Findings
Cross-cultural comparison reveals asymmetries between the term “hospitality” and its Chinese translations, etymologically and culturally. This study demonstrates how the Chinese 主–客 paradigm is both hierarchal in nature and centred on the role and interests of the host. It further compares this paradigm with its Western counterpart along five different dimensions.

Research limitations/implications
The specific Chinese norms for the host–guest paradigm synthesized here could prompt both academicians and operators to question the cultural attachments associated with hospitality by participants and the cultural differences in hospitality transactions and management. The cultural sensitivity modelled here is intended to facilitate harmony between a hospitality setting and the culture in which it is embedded.

Originality/value
This conceptual paper is the first in the Anglophone literature to explore the Chinese cultural roots of the concepts “host” and “guest”. The linguistic perspective used in this study allows the concept of “hospitality” to be studied cross-culturally and in an interdisciplinary way, addressing a blind spot in the extant hospitality literature.
Improving job performance through identification and psychological capital
Authors: Tüzün Ipek Kalemci , Çetin Fatih , Basim H. Nejat 
Published: November 2017

Purpose
The purpose of this paper is to increase understanding of the link between various identification foci and performance, and to test whether one’s psychological capital (PsyCap) can explain the influence of collective or relational identification on job performance.

Design/methodology/approach
The study sample comprised 235 academicians working in a foundation university from Turkey. The questionnaires were practiced in two different time intervals with using an identifier coding system for avoiding common method bias issues. The authors used structural equation modeling with using AMOS v23.0.

Findings
The results showed that PsyCap has positive effects on the job performance and work group identification flourishes employees PsyCap level; there is no evidence of any mediating effect of PsyCap on the relationships between various organizational identification foci and job performance.

Originality/value
This study extends previous research by providing evidence of that rather than the other identification target (organization, work unit, and career) identification with supervisor influenced on job performance.
The money laundering risks and vulnerabilities associated with MMM Nigeria
Authors: Esoimeme Ehi Eric 
Published: November 2017

PurposeThis paper aims to help build awareness with the regulatory, enforcement and customs authorities as well as reporting entities about money laundering risks and vulnerabilities of the Mavrodi Mondial Movement (MMM) scheme, and how to mitigate them.Design/methodology/approachThe research took the form of a desk study, which analyzed various documents and reports such as the Financial Action Task Force (FATF) typologies reports in 2006, 2008, 2010, 2013 and 2014 on new payment methods (NPMs) which focused on the potential for NPM to be misused by criminals; the identification of risk factors which can significantly differ from one new payment product or service to another, depending on functionality; and risk mitigants which can be tailored to a particular new payment product or service to address its specific risk profile.FindingsThis paper presents the following findings and recommendations: high-risk customers such as politically exposed persons (PEPs) could exploit the non-face-to-face feature of MMM by using the identity of low-risk customers (e.g. pensioners) to open MMM accounts. The Bitcoin funding option may present a higher money laundering risk than Bank wire, MasterCard, Visa Debit and Interac. The electronic nature of Bitcoins provides in principle a good foundation for effective record keeping and the monitoring of transactions. The money laundering risks associated with Goldmoney are very minimal when compared to Bitcoin. MMM Nigeria is therefore recommended to adopt Goldmoney as its preferred method of online payment for MMM transactions.Originality/valueWhile most publications on MMM are focused on fraud, this paper focuses on the money laundering risks and vulnerabilities associated with the MMM scheme.
Detection mechanisms under Kenya’s anti-money laundering regime: omissions and loopholes
Authors: Gikonyo Constance 
Published: November 2017

Purpose
This paper aims to detect the methods that facilitate the identification of potential money laundering activities in Kenya. Kenya is a transit point for international drug traffickers and trade-based money laundering. Hence, it is vulnerable to money laundering and consequently, it is necessary to examine the potency of its first lines of defence and its weaknesses.

Design/methodology/approach
The research is secondary in nature. It is based on reviewing relevant literature and analyzing the Proceeds of Crime and Anti-Money Laundering Act (POCAMLA) and the Proceeds of Crime and Anti-Money Laundering Regulations (POCAMLR). Both form the core of Kenya’s anti-money laundering regime.

Findings
Generally, the identified methods can facilitate identification of proceeds of crime and possible laundering activity. However, there are challenges in the provisions that could reduce effectiveness. These include intrinsic loopholes and implementation challenges, in the provisions relating to accountants, precious stone and metal dealers and the hawala system. Additionally, there is the key omission of car dealers and legal professionals from the mechanisms for detecting money laundering.

Originality/value
Given Kenya’s money laundering susceptibility, it is necessary and prudent to critically examine its mechanisms for detecting money laundering. The paper seeks to make a practical and scholarly contribution in filling this extant gap. This paper can trigger further discussions as well as the necessary legislative and policy changes. This would positively enhance the success of Kenya’s anti-money laundering regime in detecting money laundering activities.
The terrorist resourcing model applied to Canada
Authors: O’Halloran Patrick J. , Leuprecht Christian , Dizboni Ali Ghanbar Pour , Green Alexandra , Adelstein David 
Published: November 2017

Purpose
This paper aims to examine whether the money laundering/terrorist financing (ML/TF) model excludes important aspects of terrorist resourcing and whether the terrorist resourcing model (TRM) provides a more comprehensive framework for analysis.

Design/methodology/approach
Research consisted of case studies of resourcing activities of four listed terrorist organizations between 2001 and 2015: the Liberation Tigers of Tamil Eelam (LTTE), Hamas, a grouping of Al Qaeda-inspired individuals and entities under the heading “Al Qaeda inspired” and Hezbollah.

Findings
The most prevalent resourcing actors observed were non-profit organizations/associations, and the most prevalent form of resourcing was fundraising that targeted individual cash donations of small amounts. Funds were pooled, often passed through layers of charitable organizations and transmitted through chartered banks. The TRM is indeed found to provide a more comprehensive framework for identifying sources of resourcing and points of intervention. However, it does not in itself recommend effective means of response but it has implications for counter-resourcing strategies because it identifies resourcing actors and nodes where counter-resourcing could occur.

Originality/value
This paper advances the state of knowledge of terrorist resourcing activities in Canada and about the value of doing so through the analytical lens of the TRM as opposed to the predominant ML/TF model.
Diverse effect of phosphatidylcholine biosynthetic genes on phospholipid homeostasis, cell autophagy and fungal developments in Metarhizium robertsii
Authors: Chen Yixiong , Li Bing , Cen Kai , Lu Yuzhen , Zhang Siwei , Wang Chengshu 
Published: November 2017

SummaryPhosphatidylcholine (PC) plays an important role in maintaining membrane integrity and functionality. In this study, two key genes (Mrpct and Mrpem) putatively involved in the cytidine diphosphate (CDP)‐choline and phosphatidylethanolamine N‐methyltransferase (PEMT) pathways for PC biosynthesis were characterized in the insect pathogenic fungus Metarhizium robertsii. The results indicated that disruption of Mrpct did not lead to any reduction of total PC content but impaired fungal virulence and increased cellular accumulation of triacylglycerol. Deletion of Mrpem reduced PC content and impaired fungal conidiation and infection structure differentiation but did not result in virulence defects. Lipidomic analysis revealed that deletion of Mrpct and Mrpem resulted in dissimilar effects on increase and decrease of PC moieties and other phospholipid species accumulations. Interestingly, we found that these two genes played opposite roles in activation of cell autophagy when the fungi were grown in a nutrient‐rich medium. The connection between PC metabolism and autophagy was confirmed because PC content was drastically reduced in Mratg8Δ and that the addition of PC could rescue null mutant sporulation defect. The results of this study facilitate the understanding of PC metabolism on fungal physiology.

SummaryArsenic, a highly cytotoxic and cancerogenic metalloid, is brought into the biosphere through geochemical sources and anthropogenic activities. A global biogeochemical arsenic biotransformation cycle exists in which inorganic arsenic species are transformed into organoarsenicals, which are subsequently mineralized again into inorganic arsenic compounds. Microorganisms contribute to this biotransformation process greatly and one of the organoarsenicals synthesized and degraded in this cycle is arsenobetaine. Its nitrogen‐containing homologue glycine betaine is probably the most frequently used compatible solute on Earth. Arsenobetaine is found in marine and terrestrial habitats and even in deep‐sea hydrothermal vent ecosystems. Despite its ubiquitous occurrence, the biological function of arsenobetaine has not been comprehensively addressed. Using Bacillus subtilis as a well‐understood platform for the study of microbial osmostress adjustment systems, we ascribe here to arsenobetaine both a protective function against high osmolarity and a cytoprotective role against extremes in low and high growth temperatures. We define a biosynthetic route for arsenobetaine from the precursor arsenocholine that relies on enzymes and genetic regulatory circuits for glycine betaine formation from choline, identify the uptake systems for arsenobetaine and arsenocholine, and describe crystal structures of ligand‐binding proteins from the OpuA and OpuB ABC transporters complexed with either arsenobetaine or arsenocholine.
Deep ocean prokaryotic communities are remarkably malleable when facing long‐term starvation

Published: November 2017

SummaryThe bathypelagic ocean is one of the largest ecosystems on Earth and sustains half of the ocean's microbial activity. This microbial activity strongly relies on surface‐derived particles, but there is growing evidence that the carbon released through solubilization of these particles may not be sufficient to meet the energy demands of deep ocean prokaryotes. To explore how bathypelagic prokaryotes respond to the absence of external inputs of carbon, we followed the long‐term (1 year) dynamics of an enclosed community. Despite the lack of external energy supply, we observed a continuous succession of active prokaryotic phylotypes, which was driven by recruitment of taxa from the seed bank (i.e., initially rare operational taxonomic units [OTUs]). A single OTU belonging to Marine Group I of Thaumarchaeota, which was originally rare, dominated the microbial community for ∼ 4 months and played a fundamental role in this succession likely by introducing new organic carbon through chemolithoautotrophy. This carbon presumably produced a priming effect, because after the decline of Thaumarchaeota, the diversity and metabolic potential of the community increased back to the levels present at the start of the experiment. Our study demonstrates the profound versatility of deep microbial communities when facing organic carbon deprivation.
Spatial Practices and the Institutionalization of Water Sanitation Services in Southern Metropolises: The case of Jakarta and its Kampung Kojan
Authors: Putri Prathiwi W. , Moulaert Frank 
Published: November 2017

AbstractThis article examines the spatial practices and forms of institutionalization in the water and water sanitation sector in Jakarta, capital of Indonesia, and especially in Kampung Kojan in the Kalideres subdistrict of Jakarta. To this end, it develops a three‐layered analytical framework viewing the city as a multi‐scalar socio‐ecological system in which different forms of human–water relations and their institutionalization are found. Particular attention is given to informality in this system and how it interacts with ‘regular’ state and corporate market sector practices. Within these interactive dynamics, informality is not only understood as a survival strategy but also as a creative practice connecting various social‐ecological opportunities, traditional and contemporary technologies and modes of institutionalization to each other. Ongoing institutionalization processes in the formal and informal economy, as well as between them, are analysed. Opportunities to integrate and regularize the diverse water sanitation services into community‐led closed water–wastewater cycles capable of ensuring public health and sustaining a bio‐hydrological balance at the local level are explored.
Spray Drying of Spinach Juice: Characterization, Chemical Composition, and Storage
Authors: Çalışkan Koç Gülşah , Nur Dirim Safiye 
Published: November 2017

AbstractThe 1st aim of this study is to determine the influence of inlet and outlet air temperatures on the physical and chemical properties of obtained powders from spinach juice (SJ) with 3.2 ± 0.2 °Brix (°Bx). Second, the effect of 3 different drying agents (maltodextrin, whey powder, and gum Arabic) on the same properties was investigated for the selected inlet/outlet temperatures (160/100 °C) which gives the minimum moisture content and water activity values. For this purpose, the total soluble solid content of SJ was adjusted to 5.0 ± 0.2 °Bx with different drying agents. Finally, the effects of different storage conditions (4, 20, and 30 °C) on the physical and chemical properties of spinach powders (SPs) produced at selected conditions were examined. A pilot scale spray dryer was used at 3 different inlet/outlet air temperatures (160 to 200 °C/80 to 100 °C) where the outlet air temperature was controlled by regulating the feed flow rate. Results showed that the moisture content, water activity, browning index, total chlorophyll, and total phenolic contents of the SP significantly decreased and pH and total color change of the SP significantly increased by the addition of different drying agents (P < 0.05). In addition, the changes in the above‐mentioned properties were determined during the storage period, at 3 different temperatures. It was also observed that the vitamin C, β‐carotene, chlorophyll, and phenolic compounds retention showed first‐order degradation kinetic with activation energy of 32.6840, 10.2736, 27.7031, and 28.2634 kJ/K.mol, respectively.
