Framing hybrid exchanges in subsistence contexts
Authors: Mwiti Fredah Gakii , Onyas Winfred Ikiring 
Published: June 2018

Purpose
The purpose of this paper is to deepen the understanding of subsistence exchange practices and their contribution to international marketing theory and practice. It draws on the notion of embeddedness to examine the hybrid exchange practices unfolding within subsistence communities, and between subsistence communities and (international) firms.

Design/methodology/approach
The paper reports two ethnographic studies conducted in low-income farming and slum communities in Uganda and Kenya, respectively. Both studies involved participant observation, interviews, field note-taking and visual methods.

Findings
The findings demonstrate that hybrid exchange systems prevail in subsistence contexts, supporting both market and non-market logics simultaneously. Actors remain deeply embedded in their social worlds during exchange, making it problematic to disentangle social relations from market exchanges.

Research limitations/implications
The study suggests implications for international firms interested in forging business partnerships with subsistence actors. It calls for international marketers to surpass the traditional marketing roles and develop competences that enable firms to meaningfully embed in subsistence contexts. Further research could explore how international marketers could develop such competences.

Originality/value
The paper draws from diverse exchange literature to demonstrate how subsistence actors become actively involved in shaping hybrid exchanges that (potentially) incorporate international firms. The study calls for a broader understanding of international marketing, which accounts for the embedded marketing practices entailed in serving subsistence markets. It concludes that categorizing exchanges as either economic or social is problematic as both forms co-evolve to constitute multiple levels of intra-community, local marketplace and extensive hybrid exchanges.
Visual-inertial SLAM method based on optical flow in a GPS-denied environment
Authors: Chen Chang , Zhu Hua 
Published: June 2018

Purpose
This study aims to present a visual-inertial simultaneous localization and mapping (SLAM) method for accurate positioning and navigation of mobile robots in the event of global positioning system (GPS) signal failure in buildings, trees and other obstacles.

Design/methodology/approach
In this framework, a feature extraction method distributes features on the image under texture-less scenes. The assumption of constant luminosity is improved, and the features are tracked by the optical flow to enhance the stability of the system. The camera data and inertial measurement unit data are tightly coupled to estimate the pose by nonlinear optimization.

Findings
The method is successfully performed on the mobile robot and steadily extracts the features on low texture environments and tracks features. The end-to-end error is 1.375 m with respect to the total length of 762 m. The authors achieve better relative pose error, scale and CPU load than ORB-SLAM2 on EuRoC data sets.

Originality/value
The main contribution of this study is the theoretical derivation and experimental application of a new visual-inertial SLAM method that has excellent accuracy and stability on weak texture scenes.
Energy-optimal motion planning of a biped pole-climbing robot with kinodynamic constraints
Authors: Zhou Xuefeng , Jiang Li , Guan Yisheng , Zhu Haifei , Huang Dan , Cheng Taobo , Zhang Hong 
Published: June 2018

Purpose
Applications of robotic systems in agriculture, forestry and high-altitude work will enter a new and huge stage in the near future. For these application fields, climbing robots have attracted much attention and have become one central topic in robotic research. The purpose of this paper is to propose an energy-optimal motion planning method for climbing robots that are applied in an outdoor environment.

Design/methodology/approach
First, a self-designed climbing robot named Climbot is briefly introduced. Then, an energy-optimal motion planning method is proposed for Climbot with simultaneous consideration of kinematic constraints and dynamic constraints. To decrease computing complexity, an acceleration continuous trajectory planner and a path planner based on spatial continuous curve are designed. Simulation and experimental results indicate that this method can search an energy-optimal path effectively.

Findings
Climbot can evidently reduce energy consumption when it moves along the energy-optimal path derived by the method used in this paper.

Research limitations/implications
Only one step climbing motion planning is considered in this method.

Practical implications
With the proposed motion planning method, climbing robots applied in an outdoor environment can commit more missions with limit power supply. In addition, it is also proved that this motion planning method is effective in a complicated obstacle environment with collision-free constraint.

Originality/value
The main contribution of this paper is that it establishes a two-planner system to solve the complex motion planning problem with kinodynamic constraints.
Analysis of pipe-bursting construction risks using probability-impact model
Authors: Adamtey Simon , Onsarigo Lameck 
Published: June 2018

Purpose
Civil utility projects, both open-trench and trenchless, are subject to risk. These risks have both direct and indirect effect on project cost, schedule, quality and safety. It is therefore critical for the project management team to include risk management as an integral part of their project planning and execution. The purpose of this study is to identify the pipe-bursting construction risks and determine their probability of occurrence and cost impact and provide the appropriate responses to mitigate the identified risks.

Design/methodology/approach
This is an exploratory design using an industry-wide questionnaire survey to collect data on the probability of occurrence and impact of risks on cost of pipe-bursting projects. A probability-impact model was used to categorize the risks to determine their criticality and the appropriate risk responses.

Findings
The model revealed that majority of the analyzed risks have low impact-low probability of occurrence and high impact-low probability of occurrence. Undocumented repairs to host pipe was the only risk identified as having high probability of occurrence and high impact on cost. The risk responses suggest a combination of risk transfer, reduction and acceptance to be appropriately applied to mitigate the risks. A discussion on the good practices indicates that most pipe-bursting operations can be done safely and successfully if site and project conditions are known before bursting and the appropriate measures are taken to address those conditions.

Research limitations/implications
Although the identified risks may apply to other utility construction methods, the focus of this research is limited to risks that occur during the construction phase of a pipe-bursting construction project.

Practical implications
Risk management is very critical to the success of any construction project. Identification and assessment of risks alone will not serve the purpose of risk management unless meaningful ways to mitigate those risks in a structured way are planned. The probability-impact model for the pipe-bursting construction risks with the mitigation strategies will help owners, engineers and contractors plan for and adequately respond to these risks. Additionally, a logical assessment of the risks will aid in effective decision-making regarding the management of the project.

Originality/value
Extensive literature review indicates that there is no existing literature on the probability of occurrence and impact on cost of risks in pipe-bursting projects. This paper presents the results of a wide-ranging analysis on construction risks in pipe-bursting projects. This is the first analysis incorporating the use of the probability-impact model to determine the criticality of various pipe-bursting construction risks.

Authors: Ahmed Ishfaq , Rehman Wasim-ul , Ali Fouzia , Ali Ghulam , Anwar Farooq 
Published: June 2018

PurposeThe purpose of this paper is to value the role of organizational virtuousness in predicting employee performance through mediation of affective well-being and work engagement.Design/methodology/approachData were collected through questionnaires from 487 banking employees from 60 branches of ten banks.FindingsAnalysis through structural equation modeling proves that virtuousness positively predicts employees’ well-being and engagement, which in turn influence their performance. Furthermore, both well-being and engagement proved to be partial mediation in the relation, where well-being had stronger explanatory role.Originality/valueThis study offers novel explanatory mechanism in the relationship of employee performance and organizational virtuousness, where in past studies such mediation mechanism has not received due attention.
Leader-follower crossover: exhaustion predicts somatic complaints via StaffCare behavior
Authors: Köppe Christina , Kammerhoff Jana , Schütz Astrid 
Published: June 2018

PurposeThe purpose of this paper is to examine the direct and indirect crossover effects of leaders’ exhaustion on followers’ somatic complaints by testing leaders’ health-oriented behavior toward employees as a possible underlying mechanism.Design/methodology/approachA two-wave online study using data from different sources was conducted. In a sample of 106 leaders and followers, leaders were paired with one or two followers. Leaders rated their level of exhaustion at Time 1, and followers rated their leaders’ health-oriented leadership behavior (i.e. StaffCare behavior) and their own level of somatic complaints three months later (Time 2).FindingsResults provided evidence of an indirect crossover effect from leaders’ exhaustion to followers’ somatic complaints through StaffCare behavior. There was no direct crossover effect.Practical implicationsFindings suggest that organizations should attend to leaders’ health as a means to allow for StaffCare behavior and thus protect employee health.Originality/valueStaffCare behavior represents a new concept that focuses on health-related aspects of leadership. This is the first study to take an in-depth look at the question of how this leadership behavior is tied to crossover from leader exhaustion to follower health.
The phenomenon of collaboration in a life science network
Authors: Friberg Torbjörn 
Published: June 2018

PurposeThe purpose of this paper is to outline the operative meaning of collaboration in a life science network.Design/methodology/approachData were collected through participatory observations and interviews between 2014 and 2015. The data presented were derived from field notes from participant observations, interviews and documents within a life science network in the Öresund region (southern part of Sweden and the Copenhagen area).FindingsThe findings suggest that collaboration within the life science network should be viewed as a lively, organizational assembly in the process of becoming, in contrast to the idea that it is operating on the basis of organic principles. Collaboration thus could be viewed as consisting of self-subsistent parts (participants and organizations) that are detached and plugged into different collaborative networks.Originality/valueIn the context of the emerging idea of re-building the state welfare system with the economic support of producing and selling knowledge, there seems to be a growing interest, especially from the point of view of policymakers, in the phenomenon of collaboration. This paper offers exclusive ethnographic illustrations into the heterogeneity of collaboration.
Insider or outsider? Exploring the fluidity of the roles through social identity theory
Authors: Bruskin Signe 
Published: June 2018

Purpose
The purpose of this paper is to explore the fluidity of the fieldwork roles “insider” and “outsider.” The paper aims to move the discussion of insiders from an a priori categorized status and contribute to the literary insider–outsider debate by unfolding the micro process of how the role of an insider is shaped in situ. Grounded in empirical examples, the paper illustrates how the researcher’s role is shaped through interactions with organizational members and by context.

Design/methodology/approach
The paper is based on an ethnographic study in an IT department of a Nordic bank and draws on empirical material generated through a combination of data: shadowing, interviews, observations and documents. Excerpts from fieldnotes are included to invite the reader into “the scenes” played out in the field and are analyzed in order to illustrate the shaping of roles in situ.

Findings
The study finds that, independent of the researcher’s role as sponsored by the organization, the interactions with organizational members and context determine whether the researcher is assigned a role as insider or outsider, or even both within the same context.

Originality/value
The paper contributes with a new discussion of how the roles of insiders and outsiders are fluid by discussing the shaping of the roles in situ. By drawing on relational identity theories, the paper illustrates how interactions and context influence the researcher’s role, grounded in empirical examples. In addition, the paper discusses what the assigned roles enable and constrain for the ethnographer in that particular situation.
Equity and public finance issues in the state subsidy of public transit
Authors: Hudspeth Nancy , Wellman Gerard 
Published: June 2018

PurposePublic transit is an essential service for people without access to an automobile, particularly those who are low income, elderly, or with disabilities. Previous research has found that large urban transit agencies receive less state funding per ride provided than suburban agencies. The paper aims to discuss this issue.Design/methodology/approachUsing data from the National Transit Database for 37 of the largest US transit agencies, the authors create a panel data set of services provided and sources of operating funds for the period 1991-2009. The authors develop an equity index that represents the difference between the share of state funding that an agency receives and the share of the total transit rides in the state that it provides. The authors use fixed-effects regression modeling to examine the determinants of fiscal balance and the equity index.FindingsThe authors find that the share of an agency’s operating funds that come from dedicated taxes is a significant predictor of fiscal health as measured by its fiscal balance; reliance on passenger fares and provision of bus service are significant predictors of operating deficits. The equity index finds that large agencies receive less than their fair share of state transit funding based on ridership.Practical implicationsDedicated tax revenues are a key ingredient to transit agencies’ fiscal stability. Transit agencies’ fiscal condition in states and localities that do not have a dedicated tax could benefit from such a tax.Social implicationsTransit is an essential service for people who are unable to drive or own an automobile; funding inequities maintain old patterns of segregation and isolation for “transit dependents.”Originality/valueThis study supports earlier research finding that large agencies receive less than their fair share of state funding based on ridership. It contributes to the literature on transportation equity and transit finance.
Is transparency a double-edged sword in citizen satisfaction with public service? Evidence from China’s public healthcare
Authors: Yang Yongheng 
Published: June 2018

PurposeThe purpose of this paper is to explain the direct and moderating effects of perceived transparency on citizen satisfaction with public healthcare services.Design/methodology/approachThis paper extends the classic framework of service quality, value and satisfaction by adding perceived transparency as an essential component, applies service-dominant logic to develop hypotheses regarding the effects of transparency and empirically tests the extended framework with secondary household survey data on China’s public healthcare.FindingsThe classic framework of service quality, value and satisfaction that originated from the private sector is robust in public service. Perceived transparency has a positive impact on perceived value and citizen satisfaction, but the positive effects of service quality and perceived value on citizen satisfaction were weakened with the increasing level of perceived transparency.Research limitations/implicationsPerceived transparency is a double-edged sword regarding citizen satisfaction: although transparency increases perceived value and satisfaction by enhancing citizens’ service co-creation and inspiring citizen confidence, increased transparency raises citizens’ expectations for service products, which subsequently dampens the positive effects of service quality and perceived value on citizen satisfaction.Practical implicationsIn a context with higher transparency, local authorities must learn to manage citizen expectations that influence satisfaction, and increase the probability of satisfaction by avoiding too high citizen expectations.Originality/valueThis paper highlights the importance of transparency in enhancing public service co-creation, and contributes a novel perspective on the effects of transparency in the formation of citizen satisfaction, which may serve as the starting point for studying the role of transparency in public affairs.
Situational leadership theory: a test from a leader-follower congruence approach
Authors: Thompson Geir , Glasø Lars 
Published: June 2018

PurposeEmpirical tests of Hersey and Blanchard’s situational leadership theory (SLT) have demonstrated that the assessment of follower competence and commitment, critical contextual features dictating optimal leadership style, poses several problems in testing the validity of this theory. As well, most previous studies have used leader rating as the only information source in making these assessments. The purpose of this paper is to use the degree of agreement between leader rating and follower self-rating to determine follower competence and commitment, and consequently an optimal leadership style.Design/methodology/approachSurvey data collected from both supervisors and employees in business organizations in Norway were analyzed to test the predictions put forward in SLT.FindingsThe results show that SLT principles are supported when leader rating and follower self-rating are congruent. However, no support was obtained for Blanchard’s suggestion to apply followers’ self-ratings of competence and commitment in the case of discrepant ratings of follower development level. But data do support the contention that leader assessment would be a better basis for providing followers with appropriate direction and support.Originality/valueSo far SLT has been a very popular but as yet under-researched theory. An important contribution of the present study is by making SLT an evidence-based theory, as opposed to just being intuitively sound. As such, the authors think SLT in an updated “convergent” version should be applied in organizations and taught in leadership development programs.
How does subsidiary autonomy influence performance? The moderating role of uncertainty
Authors: Chen Zhijun , Zheng Li 
Published: June 2018

Purpose
The purpose of this paper is to explore the influence of subsidiary autonomy on subsidiary performance under uncertainty. Based on previous studies, the authors classify subsidiary autonomy into two categories, namely, strategic autonomy and operational autonomy, and investigate the relationships between these two categories of subsidiary autonomy and subsidiary performance under uncertainty.

Design/methodology/approach
The sample includes the subsidiaries listed on the Shanghai and Shenzhen Stock Exchanges in China from 2012 to 2015. Ordinary least squares are used to examine the hypotheses.

Findings
The results indicate that strategic autonomy is negatively related to subsidiary performance, whereas operational autonomy is positively associated with subsidiary performance. Moreover, uncertainty weakens the negative strategic autonomy-subsidiary performance linkage.

Originality/value
The findings of this study indicate that two categories of subsidiary autonomy (strategic autonomy, operational autonomy) have different effects on subsidiary performance. Moreover, uncertainty moderates the above relationships. This study explores the relationship between subsidiary autonomy and subsidiary performance and provides a useful guidance for the selection of subsidiaries’ management modes.
A contingent perspective on the synergistic effect of governance mechanisms on sustainable supply chain
Authors: Ni Wenbin , Sun Hongyi 
Published: June 2018

PurposeLiterature proposes that implementing supplier assessment and supplier collaboration simultaneously may lead to better sustainable performance. The purpose of this paper is to empirically examine the proposition by considering the contingent effects of two contextual factors, the environmental dynamism and the stakeholder pressure on sustainability.Design/methodology/approachFour configurations of governance mechanisms are identified according to the different levels of implementing supplier assessment and supplier collaboration. The performances of the four configurations are compared against the levels of environmental dynamism and stakeholder pressure. The empirical data from the sixth round of International Manufacturing Strategy Survey (IMSS) are used.FindingsThis paper found that the governance configuration with the highest level of implementing both governance mechanisms leads to the best performance. The synergistic effect that supplier assessment and collaboration complement each other to achieve better performance is verified. However, the synergistic effect holds robust only when the environmental dynamism and stakeholder pressure are high. The synergistic effect vanishes in the social and environmental performance when the environmental dynamism is low. The effect also vanishes in the environmental performance when the stakeholder pressure is low. No synergistic effect was found in business performance.Originality/valueThis paper reveals the complementarity between supplier assessment and supplier collaboration when they are implemented at a reasonably high level. It also reveals the importance of the fit of governance mechanisms under different external contexts. The results contribute to reconciling the disputes about the effectiveness of governing supplier relationship to achieve the sustainability along a supply chain.
