Abstract
Purpose
This paper aims to address the performance of different subgrid-scale models (SGS) for hydro- (HD) and magnetohydrodynamic (MHD) channel flows within a collocated finite-volume scheme.
Design/methodology/approach
First, the SGS energy transfer is analyzed by a priori tests using fully resolved DNS data. Here, the focus lies on the influence of the magnetic field on the SGS energy transport. Second, the authors performed a series of 18 a posteriori model tests, using different grid resolutions and SGS models for HD and MHD channel flows.
Findings
From the a priori analysis, the authors observe a quantitative reduction of the SGS energy transport because of the action of the magnetic field depending on its orientation. The a posteriori model tests show a clear improvement because of the use of mixed-models within the numerical scheme.
Originality/value
This study demonstrates the necessity of improved SGS modeling strategies for magnetohydrodynamic channel flows within a collocated finite-volume scheme.

Abstract
Purpose
Salespeople are at the forefront of the external environment where they act as the first responders to critical events and their resulting business turbulence. How the salesforce responds to turbulence is, therefore, of great interest both theoretically and in practice. The paper aims to rekindle interest in agility selling, which is the most adequate behavioral sales model to exploit environmental uncertainty.
Design/methodology/approach
An organizational autoethnography complemented with data from in-depth interviews with key salespeople involved in turbulence resulted in the development of eight case studies.
Findings
Salespeople use agility selling through four possible responsive roles. They amplify, innovate, cooperate or mitigate turbulence to exploit its ensuing opportunity or minimize its negative effect for both the supplier and the customer. The article enhances the agility selling model by putting three core abilities in the forefront: (1) forecasting turbulence from critical events, (2) responding to changes quickly and adequately and (3) exploiting changes as opportunities.
Research limitations/implications
The article argues that critical events are the cause of the turbulence that the salesforce must deal with before it hits the dyad. Agility selling represents an untapped research opportunity in business-to-business sales, and sales management, as well as within the overall agile organization.
Practical implications
Sales organizations would greatly benefit in implementing training of agility selling’s core abilities because responsiveness is a valuable tool for salespeople in times of turbulence.
Originality/value
The study is the first to empirically demonstrate the existence of agility selling.

Abstract
Current TM literature shows a lack of empirical research on the actual implementation of TM as a mediating step in the TM process, and on the role of the line managers in that stage. Bos, Thunnissen and Pardoen look into this ‘black box’ of TM and focus in their study on the role of line managers in the actual implementation of TM. In particular, the impact of the line manager’s leadership style on employee reactions to TM is investigated, as well as the constraints in the line manager’s role in executing TM. Their exploratory, quantitative study on the role of the line manager demonstrates that the line manager can support employees in deploying and developing their talents, and when they do so employees feel more empowered and committed to the job. Most line managers are willing to support their employees in developing and utilizing their talents, and that they think they have the capability of doing. However, the study shows that in many cases the line manager overestimates his/her actions regarding the mobilization of employee’s talents, and employees often have different perceptions of the line manager’s behaviour to TM than the line manager him/herself. The bigger the gap in perceptions, the more it has a negative effect on employees’ cognitive and affective reactions to TM. The authors call for more research on the role of the line manager in TM, and in particular on this gap in perceptions.

Abstract
Purpose
The purpose of this paper is to describe the relationship between project work and stress. It examines how the conditions of project work negatively impact on an individual’s mental and physical state of well-being, consequentially reducing organisational performance.
Design/methodology/approach
The authors systematically review the project management literature for sources of stress or stressors as it relates to Cooper and Marshall’s (1976) model of stress at work. The authors perform a thematic analysis on these stressors to reveal the “sub-stressor” conditions of project work.
Findings
A “model of projects as a source of stress at work” is developed. It shows the relationship between the sub-stressors of project work and the ill effects they have on mental and physical well-being of the project workforce.
Research limitations/implications
The findings of this study are constrained by the limits of a literature review process. This study has implications for research on stress in project work, as studies can benefit from the “model of projects as a source of stress at work”, which can be continually advanced to gain insights on the minimisation of physical and mental distress.
Practical implications
Many sectors including health, education, policing, aviation and military provide scenario-based training. In project management, a greater understanding of stressful scenarios and counter measures would improve health outcomes for project staff, human relations and project outcomes.
Originality/value
The study presents a comprehensive model of projects as a source of stress at work. It draws attention to the burden and cost of anxiety and stress placed on the project workforce. It makes the case for organisations and employees to take responsibility for the well-being of project staff.

Abstract
Purpose
Food safety management systems (FSMSs) are implemented in food supply chains primarily to adhere to regulations as well as meet customer requirements. The literature contains examples of successful and failed implementation of FSMSs, including the influencing factors. This paper aims to explore the literature on the effectiveness factors of FSMSs to identify the literature findings, the emerging themes and suggestions for future research.
Design/methodology/approach
A systematic literature review (SLR) is used to synthesise research on the factors influencing the effectiveness of FSMSs. The methodology consists of formulating the research questions, identifying, selecting and evaluating relevant studies, analysing, synthesising and presenting findings.
Findings
The effectiveness factors of FSMSs identified from the literature are clustered into five categories, namely (1) FSMS culture; (2) FSMS inspection, verification and audit; (3) FSMS knowledge; (4) Legal regulations; and (5) Prerequisite programmes. Moreover, it was determined that the effectiveness factors featured in a variety of contexts.
Research limitations/implications
SLR is an objective, rigorous and reliable approach to exploring the effectiveness factors of FSMSs. However, the results are contingent on research studies selected for review, which depends on the research criteria used, available and accessible research studies and the criteria for inclusion and exclusion of studies. This dependency introduces bias, an intrinsic limitation of the SLR approach.
Originality/value
In this study, the effectiveness factors of FSMSs are identified utilising an SLR approach, integrating findings from previously reported research. The factors and resulting emerging themes identified in this study are beneficial, including in improving food safety management practices.

Abstract
Purpose
Emergency humanitarian medical cold chains (HMCCs) depend heavily on their supporting energy services due to end-to-end temperature requirements in volatile disaster situations. Most energy sources powering emergency HMCCs are fossil-based due to well established processes, regardless of their environmental impact. In response to the recent energy crisis and climate change, a solution to tackle this issue relies on renewable energy sources (RES), whose use has increased to promote climate resilient development. Nevertheless, RESs’ capacity to replace conventional energy services in emergency HMCCs remains poorly understood. This study aims to investigate opportunities for, and barriers to, increasing the use of RESs in emergency HMCCs, thereby enhancing their environmental sustainability.
Design/methodology/approach
Based on a review of academic and practice literature, interviews with expert practitioners on emergency HMCCs and sustainable energy, and case study examples, this research aimed to analytically generalise the phenomenon by investigating opportunities for, and barriers to, increasing the use of RESs in emergency HMCCs. The phenomenon is illustrated in a novel framework of typical HMCC, that forms a contextual basis for future research.
Findings
A conceptual framework of typical emergency HMCC shows energy-consuming sections where RES can best be increased. This research is put forth in four propositions to manage the opportunities and barriers of the transition.
Originality/value
This research is, to the best of the author’s knowledge, the first attempt to operationalise sustainability by linking energy with HMCCs’ logistical activities in complex emergency settings. The cross-findings from literature, example cases and interviews together demonstrate the need to increase the use of RES in HMCCs, and how to do it.

Abstract
This chapter examines the research practices, procedures and problems involved in a study investigating the digital lifeworlds of rural and urban youth aged 13–18 years in Nigeria. First, the chapter maps the key aspects of the ethical guidelines that were followed before and during the course of the study. The key aspects of the guidelines covered issues linked to information disclosure, assent/consent, confidentiality, potential harms to participants, and institutions, and financial compensation and other inducements. In addition, the chapter unpacks some of the ethical complexities and dilemmas that emerged during the research. Drawing on perspectives from the new sociology of childhood and youth-centred research approaches, the chapter examines both the opportunities and challenges involved in doing research with young people on digital technology within the African context. In line with a youth-centred approach, the study privileges young people’s views and voices to facilitate their full autonomy and rights to participate in research. The chapter draws attention to the important contextual influences and dynamics that can affect all aspects of the research process and shape the emergent ethical considerations. These include ethical conundrums such as adult–child power relationship, gendered relations and group dynamics, problems of language and cognition, ‘techno-shame’, shy and assertive participants, the drawbacks of conducting fieldwork in school settings and absent participants.

Abstract
Facial expression recognition by human observers is affected by subjective components. Indeed there is no ground truth. We have developed Discrete Choice Models (DCM) to capture the human perception of facial expressions. In a first step, the static case is treated, that is modelling perception of facial images. Image information is extracted using a computer vision tool called Active Appearance Model (AAM). DCMs attributes are based on the Facial Action Coding System (FACS), Expression Descriptive Units (EDUs) and outputs of AAM. Some behavioural data have been collected using an Internet survey, where respondents are asked to label facial images from the Cohn–Kanade database with expressions. Different models were estimated by likelihood maximization using the obtained data. In a second step, the proposed static discrete choice framework is extended to the dynamic case, which considers facial video instead of images. The model theory is described and another Internet survey is currently conducted in order to obtain expressions labels on videos. In this second Internet survey, videos come from the Cohn–Kanade database and the Facial Expressions and Emotions Database (FEED).

Abstract
The annual report has two parts, financial statements and narrative sections. Commentators have raised doubts about the harmony of the two parts. The financial statements are audited, therefore submitted to a form of control. The narrative sections are free style, open to confusion and manipulation. Users are potentially exposed to contradictory messages producing an effect of dissonance. We do not test the presence of dissonance for the users, but the presence of contradictory information prone to produce dissonant effect. We conduct a content analysis of the president letter and we build an index of the level of optimism contained in it. Then, we compare this index with the change in key numbers or ratios from the financial statements. Our results indicate a moderate level of divergence between the narrative sections and the accounting data. However, this level is sufficient to raise questions about the necessity to regulate the discourse accompanying the financial statements.
