AbstractOsteoglossiformes is a basal clade of teleost, originated from late Jurassic and had seen the process of continental drift. The genomic differences amongst Osteoglossiformes species should reflect the unique evolve history of that time. Here, we presented the chromosome-level genome of Heterotis niloticus which is the only omnivore species of Osteoglossidae spreading in Africa. Together with other two Osteoglossidae species genomes of Arapaima gigas and Scleropages formosus which spread in South America and Australia respectively, we found great evolutionary differences in gene families and transposable elements. Phylogenetic analysis showed that the ancestor of H. niloticus and A. gigas diverged with S. formosus at ∼106.1Mya, consistent with the time of Afro-South American drift and A. gigas speciated from the ancestor of H. niloticus and A. gigas at ∼59.2 Mya, consistent with the separation of Eurasia and North American continents. And we proposed the evolutionary traces of Osteoglossidae species based on comparative genomics analysis and their living geographic habitats. We identified loss of LINEs and LTRs, fast evolutionary rate in parallel to fast pseudogenization rate in H. niloticus and A. gigas comparing to S. formosus during the evolutionary process. We also found notable OR genes contraction in H. niloticus, which might be related to the diet transition. Taken together, we reconstructed the evolutionary process of Osteoglossidae using three representative genomes, providing a possible clue for biogeographic and evolution study of ancient teleost clade.
Peg-in-hole assembly based on master-slave coordination for a compliant dual-arm robot
Authors: Huang Yanjiang , Zheng Yanglong , Wang Nianfeng , Ota Jun , Zhang Xianmin 
Published: January 2020

Purpose
The paper aims to propose an assembly scheme based on master–slave coordination for a compliant dual-arm robot to complete a peg-in-hole assembly task.

Design/methodology/approach
The proposed assembly scheme is inspired by the coordinated behaviors of human beings in the assembly process. The left arm and right arm of the robot are controlled to move alternately. The fixed arm and the moving arm are distinguished as the slave arm and the master arm, respectively. The position control model is used at the uncontacted stage, and the torque control model is used at the contacted stage.

Findings
The proposed assembly scheme is evaluated through peg-in-hole assembly experiments with different shapes of assembly piece. The round, triangle and square assembly piece with 0.5 mm maximum clearance between the peg and the hole can be assembled successfully based on the proposed method. Furthermore, three assembly strategies are investigated and compared in the peg-in-hole assembly experiments with different shapes of assembly piece.

Originality/value
The contribution of this study is that the authors propose an assembly scheme for a compliant dual-arm robot to overcome the low positioning accuracy and complete the peg-in-hole assembly tasks with different shapes parts.
Farmer innovations in financing smallholder maize production in Northern Ghana
Authors: Appiah-Twumasi Mark , Donkoh Samuel A. , Ansah Isaac Gershon Kodwo 
Published: January 2020

Purpose
The purpose of this paper is to explore smallholder agricultural financing in Ghana’s Northern region by identifying farmers’ preferred traditional and innovative financing methods and estimating the determinants of use of innovative financing methods.

Design/methodology/approach
This paper presented a list of documented traditional financing methods to farmers during in-depth interviews and employed descriptive statistics to summarize choice and amounts sourced from traditional methods. Two questions from the survey revealed a felt need for extra financing sources for credit-rationed farmers. Farmers with positive responses to either or both questions were classified as “users of innovative financing”. The authors then used a probit model to examine factors that influence decisions to use innovative financing method.

Findings
Farmers’ own savings, reinvesting past season’s profits and financing maize production with income from other commercial crops were the most popular traditional methods. The authors found complementary relations between formal and informal lending systems in the rural financial market. Smallholders also took farm and non-farm “by-day” jobs to raise income for farm investment and/or joined Village Savings and Loans Associations (VSLAs) specifically to take advantage of possible credit opportunities. These two latter methods were operationalized in this study as innovative agricultural financing. The results show that access to credit, social capital and market participation increased the likelihood of using innovative financing methods. Alternatively, farmer group membership, diversity in crop production and being a household head diminished the likelihood of innovative financing use.

Practical implications
The activities of VSLAs can be regulated and expanded to spread its benefits to more farmers. Also, creating avenues for dry season labour market participation in the region could enable farmers raise capital for farm investment.

Originality/value
This study explores existing practices and farmer innovations to agricultural financing and, by so doing, deviates from the vast literature focussing mainly on microcredit provisioning as the main model of smallholder agricultural financing in Africa.
What motivates Indian consumers’ to buy organic food in an emerging market?
Authors: Jose Heerah , Kuriakose Vijay , Koshy Moli P. 
Published: January 2020

PurposeIndian consumers are showing an increased demand for organic food products; however, little is known about their intention to buy organic foods. The purpose of this paper is to understand how fear towards conventional food products motivates an individual to buy organic food products and whether trust and perceived price as contextual factors are able to enhance the buying intention.Design/methodology/approachA total of 275 valid responses were collected using a self-administrated structured questionnaire, representative of Indian consumers. An ordinary least square regression analysis was used to analyse the effect of trust and perceived price in influencing the relationship between consumers’ fear and intention to buy organic food products.FindingsThe moderating role of trust and perceived price in enhancing the direct relation between fear and intention was established. In addition, cluster analysis results revealed that married women with children are showing a greater interest in buying organic food products.Practical implicationsThe findings of the study are of high importance to all stakeholders in organic food products, as selecting marketing practices which target consumers’ concern is an indispensable part of finding a niche for organic food products.Originality/valueThe findings suggest that even though consumers are fearful towards conventional food products, they displayed negative intention to buy organic food products when their trust towards the third party is low, thus confirming the importance of trust as a buffering agent.
Towards a responsible talent management model
Authors: Anlesinya Alex , Amponsah-Tawiah Kwesi 
Published: January 2020

PurposeThis study aims to critically examine talent management practices and strategies from ethical and responsible management perspectives.Design/methodology/approachIt achieves its aim through conceptual analysis by theorising through the lenses of talent philosophies, the organisational justice theory, the stakeholder theory and extant literature.FindingsA responsible talent management construct and mode to guide the practice of talent management in a socially responsible way is developed. It argues that inclusivity; corporate responsibility; and equity and equal employment opportunity are the key underlying principles of a responsible talent management system. This study further argues that responsible talent management practices promote achievement of multilevel sustainable outcomes such as decent work, employee well-being and organisational well-being.Practical implicationsEmphasising responsible management and ethical concerns in organisational talent strategies and practices is non-negotiable, given the current level of interest in sustainable work and employment and in the quest to achieve sustainable human and organisational outcomes through management and organisational practices.Originality/valueThe development of a responsible talent management construct and model is original and novel and is expected to shape thinking and drive new research directions in the field of talent management. It further contributes directly to knowledge and practice by demonstrating how organisations can manage their talents in a responsible way.
Exploring fear of appearing incompetent, competency pressure, tactics and perceptions in negotiations
Authors: Parlamis Jennifer , Badawy Rebecca , Haber Julita , Brouer Robyn 
Published: January 2020

PurposeThis study aims to examine how the fear of appearing incompetent (FAI) and competency pressure relates to negotiation tactics and subjective perceptions in a negotiation.Design/methodology/approachUsing a dyadic buyer/seller negotiation simulation and pre- and post-negotiation questionnaires, we assessed FAI, competency pressure, tactics and subjective perceptions of the negotiation. Mediation models were tested using path analysis adapted from Hayes (2013) PROCESS procedures. MPlus “complex” multi-level function was used to account for non-independence of observations.FindingsResults indicated that those with a higher FAI perceive more competency pressure, which is associated with greater use of competitive tactics (e.g. misrepresenting own interest, holding back information, making unreasonable offers) and lesser use of cooperative tactics (e.g. sharing helpful information, making reasonable offers, compromising). Tactics used in the negotiation mediated the relationship between competency pressure and subjective perception of the negotiation, such that competitive tactics were negatively related, and cooperative tactics were significantly positively related to subjective perception of the negotiation.Research limitations/implicationsReliability on the cooperative tactics measure was only minimally acceptable and all measures were self-report and collected during a single lab simulation session.Practical implicationsThe findings suggest that relieving competency pressure in negotiation settings could open avenues for cooperation. Gaining expertise through formal negotiation training may be one way to accomplish this.Originality/valueThis is the first known study to investigate FAI and competency pressure in a negotiation setting. We draw on an emotion–cognition–behavior framework to show that FAI is associated with competency pressure thoughts, which predict negotiation behaviors. Further, this research lends support to the notion that competitive tactics are fundamental to the mental model of a negotiation.
Work design and task conflict in interdisciplinary groups
Authors: Todorova Gergana , Brake Matthew R.W. , Weingart Laurie R. 
Published: January 2020

PurposeThe purpose of this paper is to examine the role of enriched group work design and objective and perceived expertise diversity in interdisciplinary research groups with a focus on two critical group processes: task conflict and idea sharing.Design/methodology/approachSurvey data were collected from 148 researchers and their advisors in 29 research labs at two doctorate-granting universities. The study tested the hypothesized model using hierarchical ordinary least squares regression and hierarchical linear modeling.FindingsResults showed that objective and perceived (salient) expertise diversity jointly influenced task conflict. In addition, whether task conflict had a positive or negative impact on idea sharing depended on group work design enrichment and expertise diversity salience. Idea sharing improved group outcomes over and above the effects of task conflict.Research limitations/implicationsAlthough this study could not test the causal relationships owing to a cross-sectional nature of data, it provides theoretical implications for the group work design, diversity and conflict literature.Practical implicationsGroup work design represents an important tool for stimulating idea sharing in research groups. The findings suggest that managers should consider and manage the level of expertise diversity salience and the level of task conflict to increase the effectiveness of group work design.Originality/valueThe study provides insights on when task conflict may help creative groups. Work design and diversity salience represent important contextual features. The paper also examines both the objective and perceived diversity and disentangles task conflict and idea sharing.
Normal accidents in interior firefighting operations – a study on the German system
Authors: Schmidt Kai Wilhelm 
Published: January 2020

PurposeThe purpose of this paper is to explore the reasons behind the occurrence of serious accidents during interior firefighting operations of the German fire services despite numerous and significant safety improvements.Design/methodology/approachThe paper is a case study relying on accident investigation reports from four accidents that happened in Germany between 2005 and 2016.FindingsThe study finds that the system of interior attack firefighting in Germany is a tightly coupled and complex system, as described by the normal accident theory, and that all four cases were caused by unanticipated interactions between components of the system and were therefore system accidents as described by the normal accident theory. This means that these accidents were ultimately caused by the properties of the system that make it susceptible to system accidents.Research limitations/implicationsTo prevent these accidents, there is a need to change the properties of the system that make it susceptible to system accidents.Practical implicationsThe study identifies factors that make the system inherently dangerous. Hence, practical measures can be undertaken to counter these factors and make the system safer.Originality/valueThis study is the first application of the normal accident theory to the operations of the fire services in general, and it is the first theory-guided inquiry into accidents of the German fire services. The findings of this paper provide new explanations for accidents and new approaches to improve safety during interior attack firefighting operations.
Collective action in SCM: a call for activist research
Authors: Touboulic Anne , McCarthy Lucy 
Published: January 2020

PurposeThe purpose of this paper is to explore the current focus of supply chain management (SCM) research; it considers field level and societal constraints and consequently the potential for change. It details the underlying assumptions in the field, considering the dominant paradigms and stakeholders, and how this has shaped the research we have engaged in as a community of scholars.Design/methodology/approachThis is a reflective inquiry that seeks to deconstruct the dominant discourses and paradigms in SCM. It offers alternative avenues of inquiry to “traditional” research, considering how different questions, perspectives and approaches might yield different learning for the field. offering alternative avenues to traditional research.FindingsThis is a call for collective action, for solidarity, for a re-imagining of what research in SCM could look like. Research activism is challenging and potentially risky but necessary for the research community to engage in, particularly in light of the global societal grand challenges. Change can take place in the SCM field through collective action and solidarity. Three levels of activism are explored here – acting to solve the grand challenges, acting to change the field and acting as individuals.Originality/valueThis is a “speak-out” piece, which embraces and encourages reflexivity, new methods of doing and writing research as well as different perspectives, and especially a consideration for context and multiple players in the supply chain. The authors contend that it is urgent to re-appropriate our own agency as SCM researchers.
Feasibility of smart wearables for driver drowsiness detection and its potential among different age groups
Authors: Kundinger Thomas , Yalavarthi Phani Krishna , Riener Andreas , Wintersberger Philipp , Schartmüller Clemens 
Published: January 2020

PurposeDrowsiness is a common cause of severe road accidents. Therefore, numerous drowsiness detection methods were developed and explored in recent years, especially concepts using physiological measurements achieved promising results. Nevertheless, existing systems have some limitations that hinder their use in vehicles. To overcome these limitations, this paper aims to investigate the development of a low-cost, non-invasive drowsiness detection system, using physiological signals obtained from conventional wearable devices.Design/methodology/approachTwo simulator studies, the first study in a low-level driving simulator (N= 10) to check feasibility and efficiency, and the second study in a high-fidelity driving simulator (N= 30) including two age groups, were conducted. An algorithm was developed to extract features from the heart rate signals and a data set was created by labelling these features according to the identified driver state in the simulator study. Using this data set, binary classifiers were trained and tested using various machine learning algorithms.FindingsThe trained classifiers reached a classification accuracy of 99.9%, which is similar to the results obtained by the studies which used intrusive electrodes to detect ECG. The results revealed that heart rate patterns are sensitive to the drivers’ age, i.e. models trained with data from one age group are not efficient in detecting drowsiness for another age group, suggesting to develop universal driver models with data from different age groups combined with individual driver models.Originality/valueThis work investigated the feasibility of driver drowsiness detection by solely using physiological data from wrist-worn wearable devices, such as smartwatches or fitness trackers that are readily available in the consumer market. It was found that such devices are reliable in drowsiness detection.
Hybrid on-demand greedy routing protocol with backtracking for mobile ad-hoc networks
Authors: Mahmood Baban A. , Manivanann Dakshnamoorthy 
Published: January 2020

Purpose
The purpose of this paper is to design an efficient on-demand routing protocol for mobile ad hoc networks (MANETs) which combines greedy forwarding and backtracking.

Design/methodology/approach
It uses a hybrid approach. It uses greedy approach to determine a route from source to the destination. If the greedy approach fails, then it uses a backtracking approach. Combining greedy and backtracking approaches results in a more efficient protocol.

Findings
A new routing algorithm for MANETs which performs better than some of the existing algorithms.

Research limitations/implications
A major limitation of this work is that the authors did not implement the protocol on a test bed and evaluated the performance. They neither had the infrastructure nor the resources to actually implement the protocol. Instead, like most of the researchers, they evaluated the performance of their protocol based on extensive simulation. The mobility model, the area of deployment and the density of nodes chosen to simulate the protocol are consistent with what many of the other researchers have done. Intuitively, the authors’ protocol, as the performance evaluation indicates, is likely to perform well in small networks.

Practical implications
The authors did not implement the protocol on a test bed to evaluate the performance of the protocol. The authors used simulation to study the performance of their protocol. Their simulation model is similar to many of the research works published in the literature.

Originality/value
To the authors’ knowledge, no other paper has combined the greedy and backtracking approach to design a routing protocols for MANETs.

Authors: Arayssi Sabine Imad , Bahous Rima , Diab Rula , Nabhani Mona 
Published: January 2020

Purpose
The purpose of this paper is to examine language teachers’ perceptions of practitioner research to establish an understanding whether research comprises a fundamental component in their career.

Design/methodology/approach
A qualitative study was conducted with language teachers and coordinators from various schools in Lebanon. Questionnaires were distributed to 50 language teachers, followed by semi-structured interviews conducted with language coordinators, and in-depth interviews with language teachers who are practitioner researchers.

Findings
Results indicated that research is a minority activity for language teachers due to lack of time, overwhelming working conditions and lack of flexibility in the workplace.

Research limitations/implications
There was a lack of cooperation between teachers and coordinators.

Originality/value
This study provides teachers in Lebanon with the opportunity of transforming their voice through participating in and being agents of research rather than solely observing the process which attempts to bridge theory to practice.
An analysis of the religious, social factors and income’s influence on the decision making in Islamic microfinance schemes
Authors: Mansori Shaheen , Safari Meysam , Mohd Ismail Zarina Mizam 
Published: January 2020

Purpose
Islamic microfinance schemes are designed and developed with the primary intention of poverty alleviation and fulfillment of the Islamic law requirements. The purpose of this study is to investigate the effects of religiosity, religious leader’s endorsement, social influence and income on the intention to apply for Islamic microfinance among Muslims in Malaysia.

Design/methodology/approach
This study is based on a public survey to collect primary data from various states in Malaysia. Then, structural equation modelling (SEM) was used to analyse the data set.

Findings
The results of SEM indicate significant roles for religiosity and religious leader’s endorsement as religion-based factors on intention to apply for microfinance products. Moreover, social influence (peer-pressure) is influential on the financial decision-making process. The authors also examined the moderation effect of gender on these relations and found that females, in comparison to males, tend to be more influenced by religious leader’s endorsement and social influence. On the other hand, male with higher religiosity tend to favour Islamic microfinance products more than females.

Originality/value
Findings of this study are new in many aspects, most importantly as it sheds light into the role of religiosity and religious leader’s endorsement on the decision-making process in microfinancing services.
