Published: July 2018

AbstractStandard evolutionary theories of aging postulate that reduced extrinsic mortality leads to evolution of longevity. Clownfishes of the genus Amphiprion live in a symbiotic relationship with sea anemones that provide protection from predation. We performed a survey and identified at least two species with lifespan of over 20 years. Given their small size and ease of captive reproduction, clownfishes lend themselves as experimental models of exceptional longevity.To identify genetic correlates of exceptional longevity, we sequenced the transcriptomes of Amphiprion percula and A. clarkii and performed a scan for positively-selected genes (PSGs). These were compared with PSGs detected in long-lived mole rats and short-lived killifishes revealing convergent evolution in processes such as mitochondrial biogenesis. Among individual genes, the Mitochondrial Transcription Termination Factor 1 (MTERF1), was positively-selected in all three clades, whereas the Glutathione S-Transferase Kappa 1 (GSTK1) was under positive selection in two independent clades. For the latter, homology modelling strongly suggested that positive selection targeted enzymatically important residues.These results indicate that specific pathways were recruited in independent lineages evolving an exceptionally extended or shortened lifespan and point to mito-nuclear balance as a key factor.
The history of accounting standards in French-speaking African countries since independence
Authors: Degos Jean-Guy , Levant Yves , Touron Philippe 
Published: July 2018

PurposeThe purpose of this paper is to focus on circumvolutions taken by the accounting standard-setting process in French-speaking African countries which have delayed convergence toward IFRS standards and to identify how different factors shape accounting standards in a context in which post-colonial hysteresis interact with globalization.Design/methodology/approachThis study uses archival data and interviews with key individual actors. Two case studies from two successive periods are contrasted: the design of the OCAM accounting standards in the 1970s, and the development of the SYSCOA/OHADA accounting standards during the 1990s before the partial adoption of IFRS.FindingsThe study shows the convergence toward international accounting standards in French-speaking African countries emerged from a complex, multimodal process mingling competition with collaboration and negotiation. They have followed a different path from most English-speaking African countries, where convergence to IAS/IFRS took place earlier and faster. The evidence indicates the significance of the interaction between the ex-colonization and the indigenous accounting standards, the importance of key actors and the level of the educational institutions.Research limitations/implicationsNo African written sources were located. Most of the sources used were French.Practical implicationsThe paper includes implications for the standards setting in developing countries. The examination of the development of accounting rules in French-speaking African countries between 1960 and 2010 shows the complexity of the accounting standards’ diffusion dynamic.Originality/valueThis study provides novel insights over a 30-year period of accounting standards in French-speaking African countries. This research explains why IFRS have not yet adopted in French-speaking African countries as it was in English-speaking African countries.
Stakeholder interactions and corporate social responsibility (CSR) practices
Authors: Phiri Obby , Mantzari Elisavet , Gleadle Pauline 
Published: July 2018

PurposeThe purpose of this paper is to critically explore the interactions of key stakeholders and their impact upon corporate social responsibility (CSR) practices in the Zambian copper mining sector. In particular, the authors examine the power dynamics that emerge in the stakeholder interactions.Design/methodology/approachThe authors analyse the stakeholder interactions based on the varying degrees of stakeholder salience and critical collaboration potential, and draw on rich evidence from 43 interviews with multiple stakeholders involved in CSR in the Zambia mining sector.FindingsThis paper finds stark power asymmetries in the relationship between the state, the civil society and mining companies which are exacerbated by a number of factors, including divisions within these key stakeholders themselves. Apart from power imbalances within and between stakeholders, the potential for critical collaboration at the local level is further challenged by the lack of commonly accepted social and environmental frameworks, transparency and accountability of the leadership of stakeholder groups. However, despite these power asymmetries some limited agency is possible, as civil society in particular co-opts previously dormant stakeholders to increase its own salience and, more importantly, that of the state.Originality/valueThis paper contributes to the literature on the key stakeholders’ interactions shaping CSR in developing countries by exploring these issues in a critical industry, the Zambian copper mining sector, on which the state economy is so heavily dependent.
The impact of order imbalance on returns, liquidity, and volatility in agricultural commodity markets
Authors: Volkenand Steffen , Filler Guenther , Odening Martin 
Published: July 2018

PurposeThe purpose of this paper is to investigate and compare the impact of order imbalance on returns, liquidity and price volatility in agricultural futures markets on an intraday basis. The authors examine whether order imbalance is more powerful to explain variations in asset prices compared to other indicators of trading activity, particularly trading volume.Design/methodology/approachUsing Chicago Mercantile Exchange best bid best offer data, the impact of order imbalance is analyzed via regression analyses. The analyses are carried out for corn, wheat, soy, live cattle and lean hogs in March 2008 and March 2016.FindingsResults confirm the positive relation between order imbalance and returns as well as between order imbalance and price volatility as suggested by market microstructure models. Order imbalance, however, does not generally outperform trading volume as an explanatory variable.Practical implicationsFor some contracts, returns can be predicted using lagged order imbalance. This offers the opportunity to derive profitable trading strategies.Originality/valueThis paper is one of the first attempts to explore the relationship between order imbalance and returns, liquidity and volatility for agricultural commodity futures on an intraday basis, accounting for the increased trading volume and for the high speed at which new information enters the market in an electronic trading environment.
The impact of social security policies on farmland reallocation in rural China
Authors: Huang Li , Tan Rong 
Published: July 2018

Purpose
The purpose of this paper is to explore the causality between social security policies and farmland reallocation in rural China.

Design/methodology/approach
It quantitatively analyzes the impact of each ongoing social security policy on farmland reallocation based on a data set from the 2011 China Health and Retirement Longitudinal Study (CHARLS, 2011).

Findings
The study finds that the inclination of a village farmers’ collective to reallocate farmland due to changes in the village population increased if social security policies do not effectively cover the village because farmers rely primarily on income from farmland to cover their basic living expenses. However, if social security policies provide adequate coverage, then farmers do not rely entirely on on-farm income and the likelihood of farmland reallocation decreases. Furthermore, the effectiveness of social security policies includes not only coverage but also the sufficiency of the security policies provided.

Research limitations/implications
First, the authors use only cross-sectional data in this study, which may result in biased estimation and also limit temporal examination of the impact of social security systems, farmland reallocation and related policy variables. This limitation may be especially important in China because the country is undergoing a rapid socioeconomic transition. However, the research is constrained by the available data. Furthermore, there could be endogeneity problems that are difficult to address, given the current data set. These problems could involve the impacts of village-level economic, natural and social variables, the implementation of related public policies (land development and consolidation, land expropriation, etc.) and other economic variables.

Practical implications
These findings may provide implications for related policy reform in the near future.

Originality/value
These findings may facilitate a recognition and understanding of the causality between social security policies and farmland reallocation in rural China.
A process model of how interpersonal interaction leads to effectiveness of the expatriate-host country national relationship
Authors: Wang Chun-Hsiao , Varma Arup 
Published: July 2018

PurposeThe purpose of this paper is to develop and present a conceptual model of expatriate–host country national (HCN) interaction that explains how organizations can help increase cooperation between expatriates and HCNs by facilitating interaction between expatriates and HCNs.Design/methodology/approachThe authors draw upon intergroup contact theory to develop a process model which describes the processes critical to “the effectiveness of the expatriate–HCN relationship,” from both the expatriate and HCN perspectives.FindingsHCN–expatriate interactions are critical to the success of both expatriates and HCNs, but such interactions should not be left to chance – instead, organizations should intervene and facilitate conditions that foster such interactions, which can lead to better understanding and appreciation of each other. This would ensure that both expatriates and HCNs have a better understanding of the critical role played by the other party, and thus be willing to offer relevant and necessary support at the right time.Practical implicationsPrior research reveals that most expatriate–HCN interactions are left to the individuals themselves and are thus subject to stereotypes, misperceptions and even unfulfilled expectations. By intervening in this process, and providing relevant information about each other to both parties, organizations can facilitate higher quality interactions, help reduce or remove stereotypes and increase the chances that both parties receive required and relevant information on a timely basis from each other.Originality/valueThe authors specifically discuss how interpersonal expatriate–HCN interactions allow the two parties to become acquainted with each other, when the effects of such interactions can be strengthened, and what the resultant effects are in terms of expatriate–HCN relationships.
Employee voice and silence in multinational corporations in the mobile telecommunications industry in Nigeria
Authors: Emelifeonwu Jude Chukwuemeka , Valk Reimara 
Published: July 2018

PurposeThe purpose of this paper is to explore employee voice and silence in the mobile telecommunication industry in Nigeria.Design/methodology/approachAn exploratory qualitative case study methodology was employed in this study. Participant selection was done through a purposeful intensity sampling technique, which resulted in 30 employees from two different multinational organizations and an indigenous organization taking part in in-depth interviews.FindingsFindings show the presence of fear of victimization in the Nigerian workplace embellished by the Sub-Saharan culture and the state of the labor market, which resulted in employee silence. The study revealed that the implementation of culturally adapted employee voice mechanisms within organizations in the mobile telecommunication industry in Nigeria promotes employee voice and organizational performance, whereas a lack thereof results in organizational failure.Research limitations/implicationsA limitation is that the purposive sample of employees from three organizations in the mobile telecommunications industry only permits theoretical and analytic generalization.Practical implicationsA focus on the co-creation of a high-performance work environment and the development of a powerful employee value proposition would foster employee voice.Social implicationsIt will enable multinationals operating in Nigeria understand better how to operate employee voice in order to obtain optimal performance from workers in Sub-Sahara Africa.Originality/valueThis paper contributes to the literature on employee/industrial relations by showing that a high-power-distance national culture and a high unemployment rate affect employee voice and silence, which brings to the fore the importance of adequate employee voice mechanisms through which employees express their voice in order to arrive at beneficial individual and organizational outcomes.
Unconscious bias: thinking without thinking
Authors: Oberai Himani , Anand Ila Mehrotra 
Published: July 2018

Purpose
Unconscious biases are often ignored in organizations; thus, it becomes more important to identify them so that we can build strong and competent organizations. In present dynamic and competitive business situations, you need to be well aware about those concerns of the organizations where these biases exist.

Design/methodology/approach
This paper identifies various types of unconscious biases prevailing at workplace. It also identifies different strategies which can be used to avoid them so that we can gain a competitive edge over others in market.

Findings
Unconscious biases are a fact of life; no one can deny them. Thus, it is important to identify them so that they can be eliminated, and our businesses can avoid their detrimental effects.

Research limitations/implications
Unconscious biases narrow down the pool of people in an organization and ultimately destabilize an organization’s base.

Practical implications
Unconscious biases narrow down the pool of people in the organization and ultimately destabilize an organization’s base.

Originality/value
This paper can help managers and executives to highlight the areas where these biases lie so that they can be removed easily.
Customers’ emotions in real time: measuring affective responses to service and relationship quality at the reception desk
Authors: Nordhorn Christian , Scuttari Anna , Pechlaner Harald 
Published: July 2018

PurposeThe purpose of this paper is to explore customers’ emotions during a host–guest interaction at the reception desk of a hotel. Guests’ emotional responses are analyzed in real time to understand their link to behavior and levels of service and relationship quality.Design/methodology/approachTo achieve this aim, 225 random customers experience six different types of interactions (scenarios) at a staged reception desk, representing a high/low service or relationship quality. The emotions provoked within guests are (video) recorded and analyzed with the help of SHORETM, a facial recognition software that processes four basic emotions derived from human muscular activity and calculates average emotional scores per scenario.FindingsResults reveal that customers respond more positively to service than to relationship quality. Informal approaches to interacting with guests are mixed; they can both excite or irritate customers. As with existing evidence in service marketing research, the results found out through this study demonstrate that a good service recovery process seems to immediately generate more satisfied customers than do constant high-quality standards.Research limitations/ImplicationsThe main limitations are related to the semi-staged nature of social interactions, which might cause distortions in measuring emotions and limitations in the comparability of cases.Practical ImplicationsPractical implications are directed to service designers and managers in hospitality to improve service design and ensure effective service recoveries.Originality/valueThis paper introduces a novel approach for assessing host–guest interactions in tourism based on a real-time emotional assessment of service and relationship quality in hospitality. Technologically advanced observation techniques enable in-depth analyses of actions and emotional responses between hosts and guests across time. New insights concerning service design and service recovery management are gained for practitioners and for future research.
ICT-based system for Malaysian residential maintenance projects – literature review
Authors: Ismail Zul-Atfi 
Published: July 2018

PurposeThis paper aims to identify the different system approach that is equipped with decision making processes. Presently, most maintenance organisations are still implementing conventional methods rather than fully integrated information and communication technology (ICT) to manage the information database on maintenance of residential building. The significant factor to select an ICT is much more advantageous than just a way to improve interfirm communication and cooperation on maintenance management processes and be able to perform the task needed without stressing the budget. ICT could be a pillar of fundamental importance for the implementation of an effective and efficient maintenance management on residential building and facility.Design/methodology/approachThis paper presents a review of recent publications on the topic regarding residential maintenance systems, which also takes into consideration the heritage structures, due to their same maintenance requirements and processes.FindingsThe findings reveal the need for ICT tools and techniques specific to the needs of reducing poor service delivery, inadequate financial support, poor maintenance plan and maintenance backlogs.Originality/valueThe paper concludes with a comprehensive research framework of ICT-based system as the basis for further progress in the development of the residential maintenance schemes of system.
Obese models’ effect on fashion brand attractiveness
Authors: Aagerup Ulf , Scharf Edson Roberto 
Published: July 2018

Purpose
The purpose of this paper is to investigate the effect of obese models vs normal weight models on fashion brands’ attractiveness.

Design/methodology/approach
An experiment was carried out in which 1,225 university students in Sweden and Brazil rated the attractiveness of a fashion brand worn by a normal weight model and an obese model.

Findings
The overall effect of obese models’ effect on fashion brand attractiveness was insignificant. Furthermore, neither culture nor the consumer’s own weight had a significant effect. There was, however, a significant effect of the participant’s own gender; women rate fashion brands worn by obese models significantly higher on attractiveness than they did fashion brands worn by normal weight models. Men displayed the inverse response.

Research limitations/implications
The effect of the model’s ethnicity was beyond the scope of the experiment, and the brand attractiveness scale captured only one aspect of brand character, leaving other potential brand effects for future studies.

Practical implications
Companies can use obese models with no overall brand attractiveness penalty across markets and for marketing to women of all sizes. Given men’s negative reactions, such models might however be unsuitable for the male-to-female gift market.

Social implications
The results support the use of obese models, which can lead to greater representation of larger women in the media, and consequently, reduced fat stigma.

Originality/value
The study validates the theory of user imagery, and it extends the theory by examining how different target consumers react to user imagery traits and thus provides evidence for gender bias toward obese models.
Developing a knowledge management strategy for data analytics and intellectual capital
Authors: Harlow Harold D. 
Published: July 2018

Purpose
This paper aims to build on current analytics and Big Data definitions and strategies from the literature to develop an overall strategic model connecting knowledge management strategy (KMS) for intellectual capital (IC) acquisition and business use. It also extends the IC research stages to a fifth stage of IC research including IC strategic intent.

Design/methodology/approach
A literature review highlights the connections among strategic intent, firm strategy, KMS and a data analytics strategy aligned with firm and KMS strategic intent. An extended model of the interrelationships is developed from the prior research.

Findings
A model framework was developed from the literature that connects Big Data to achieve the goals of a firm KMS and demonstrates how Big Data analytics (BDA) needs to shift from being a tactical tool to a strategic knowledge management tool directed by the overall strategy and strategic intent of the firm.

Research limitations/implications
The model presented needs to be empirically tested over a sample of companies and periods to determine if performance improves using this model.

Practical implications
Use of this model proposes that strategic intent will be enhanced and improve the capture of intellectual property derived from advanced analytics and increase sustainable advantages at firm.

Social implications
The social implications of lack of strong privacy laws coupled with the possible elimination of millions of knowledge worker jobs creates a pressing need for more research into and identification of firm’s and government’s Big Data strategic use for both good and perhaps evil.

Originality/value
The research in this paper extends current models of IC development and adds strategic intent and collective intelligence as the fifth stage of IC research and presents an overall KMS/BDA model.
