Abstract
Purpose
The main aim of this paper is to provide a living tribute of lived expert by experience and researcher Andrew Voyce.
Design/methodology/approach
Andrew provided the author with a list of names of people he might approach to write a tribute on his behalf.
Findings
The accounts describe the influence that Andrew has had both as an educator and as a trusted colleague for the people approached.
Research limitations/implications
In many ways, the voices of people with mental health problems have been marginalised. Few mental health journals, with only some exceptions, encourage lived experience contributions.
Practical implications
The mental health agenda continues to be dominated by professional groups. The remarkable individuals who continually battle with serious mental illness are often lost in official discourses.
Social implications
Despite the fact that the topic of mental health is now much more in the public domain, research tells us that the most effective anti-stigma strategy is contact with sufferers.
Originality/value
The archivist Dr Anna Sexton co-produced one of the few mental health archives that only featured people with lived experience. Andrew was one of the four people featured in it. This account “showcases” the work of this remarkable man.

This study explores the effect of video assistant referee (VAR) sponsorship on spectator response and compares it with advertising and conventional sponsorship.
Abstract
Purpose
This study explores the effect of video assistant referee (VAR) sponsorship on spectator response and compares it with advertising and conventional sponsorship.
Design/methodology/approach
An experiment with 809 subjects is conducted by analyzing 20 one-minute video clip stimuli from a Premier League soccer game divided into four formats: two formats of VAR sponsorship, advertising, and conventional sponsorship.
Findings
The results show that the indicators of recall, credibility, and perceived congruence improve when the VAR sponsorship format is used.
Originality/value
This is the first manuscript to examine the effectiveness of a new type of sponsorship: VAR sponsorship. This manuscript provides metrics that will guide practitioners on whether to use this type of sponsorship.

Abstract
Purpose
This study comparatively examines the collaborative policy mechanisms for interlocal cooperation (ILC) utilized by municipal managers in Nebraska, USA, and Norway. The research addresses differences in ILC, factors of national setting and implications for ILC management in public service delivery.
Design/methodology/approach
Over a seven-year period, the researchers collected data from 16 communities in the two countries to observe perceptions and usages of ILC. Using a policy tools theoretical framework, the authors apply a typology of collaborative mechanisms for comparative analysis.
Findings
The findings suggest that institutional orientations in the USA and Norwegian systems of government affect managerial approaches to collaborative service delivery, namely the operationalization of local governments within federal and unitary structures may influence perceptions toward the formality and specificity of ILC policy mechanisms.
Originality/value
This study offers further understanding of ILC mechanisms for public sector management. Theoretical and practical implications of ILC in a comparative international context of governmental systems for collaboration are explored.

Abstract
Purpose
Studies on this topic have shown the remarkable lubricating properties, viz. friction-reducing and anti-wear, of certain nanoparticles. This makes them potential candidates for replacing the lubrication additives currently used in automobile lubricants, especially because the latter is known to be pollutants and less efficient in some specific conditions. This has not gone unnoticed to professionals in the sector, including those commercializing these additives, the oil companies and the car industry, all of whom are following this burgeoning research area with keen interest. All of them are faced with the problem of providing lubricants that meet the needs of the technological evolution of engines while respecting ever-stricter environmental norms.
Design/methodology/approach
The impact of copper oxide (CuO) and zinc oxide (ZnO) nanoparticles on the tribological properties of the SAE-40 pure diesel oil is studied in this paper. The two nanoparticles are not oxide or deteriorate with the base oil. The average size of CuO and ZnO nanoparticles is 40 and 20 nm, respectively. Nanoparticle concentrations of 0.1 Wt.%, 0.2 Wt.%, 0.3 Wt.%, 0.4 Wt.% and 0.5 Wt.% are tested using a pin-on-disk tribometer to evaluate their impact on friction and wear. The test is carried out at different loads and rotating speeds of 58.86 N and 300 rpm, 39.24 N and 500 rpm and 78.48 N and 900 rpm at room temperature, respectively.
Findings
The obtained results of the nanolubricants are compared with those of pure diesel oil in terms of % improvement in tribological properties. However, it is observed that an increase in the nanoparticle concentrations does not guarantee to enhance the tribological properties. Similarly, increasing the applied load and the rotating speed does not lead to improving the anti-friction and anti-wear properties. The results obtained revealed that the optimal improvements in the anti-friction and anti-wear properties of the pure oil are 69% and 77% when CuO nanoparticle concentrations of 0.3 Wt.% and the ZnO nanoparticle concentrations of 0.1 Wt.% are used, where the applied load and rotating speed are 39.24 N and 500 rpm, respectively. It has also been noticed that the CuO nanolubricants have a significant impact on the anti-friction property compared with ZnO nanolubricants.
Originality/value
All these nanoparticles have been the subject of detailed investigation in this research and many key issues have been tackled, such as the conditions leading to these properties, the lubrication mechanisms coming into play, the influence of parameters such as size, structure and morphology of the nanoparticles on their tribological properties/lubrication mechanisms and the interactions between the particles and the lubricant co-additives. To answer such questions, state-of-the-art characterization techniques are required, often in situ, and sometimes an extremely complex set up. Some of these can even visualize the behavior of a nanoparticle in real time during a tribological test. The research on this topic has given a good understanding of the way these nanoparticles behave, and we can now identify the key parameters to be adjusted when optimizing their lubrication properties.

Abstract
Purpose
Dynamic governance practices are key in the administration of 21st-century airlines. Knowledge transfer via the fourth industrial revolution (4IR) is germane in governance practices. Studies have proven that the 4IR technologies could enhance airline governance and improve safety measures and productivity. The 4IR role in improving airline governance is yet to receive in-depth studies in South Africa. Thus, this study aims to investigate the governance challenges facing South African airlines in the era of 4IR.
Design/methodology/approach
This research used a qualitative research method. The main data were collected via 56 face-to-face semi-structured interviews with key stakeholders. The research achieved saturation. A thematic technique was used to analyse the collected data.
Findings
Findings reveal 12 challenges and are grouped into six governance barriers facing South African airlines in the era of 4IR. Also, findings suggest measures to mitigate governance barriers and promote 4IR technologies usage in the airline sector.
Originality/value
The study assesses critical governance challenges facing South African airlines in the era of 4IR. Understanding the importance of vital governance challenges can assist critical stakeholders in promoting innovative policies and regulations tailored towards digitalised aerospace. Thus, the study contributes strategies to improve digital innovation and reduce airline risks in South Africa. Also, it contributes to the paucity of academic literature on developing countries’ airline governance in the 4IR era and the South African aviation sector.

Abstract
Purpose
The purpose of this case study was to complement existing weeding and retention criteria beyond the most used methods in academic libraries and to consider citation counts in the identification of important scholarly works.
Design/methodology/approach
Using a small sample of items chosen for withdrawal from a small liberal arts college library, this case study looks at the use of Google Scholar citation counts as a metric for identification of notable monographs in the social sciences and mathematics.
Findings
Google Scholar citation counts are a quick indicator of classic, foundational or discursive monographs in a particular field and should be given more consideration in weeding and retention analysis decisions that impact scholarly collections. Higher citation counts can be an indicator of higher circulation counts.
Originality/value
The authors found little indication in the literature that Google Scholar citation counts are being used as a metric for identification of notable works or for retention of monographs in academic libraries.

Abstract
Purpose
Premium subsidy rates were increased in 2019 and 2020 for livestock risk protection (LRP) insurance, which is price insurance for cattle producers. The authors examined if the LRP subsidy rate changes affected the LRP coverage levels purchased by feeder and fed cattle producers.
Design/methodology/approach
The authors collected the United States Department of Agriculture Risk Management Agency summary of business sales data for daily LRP purchases from 2015 to 2023. The authors estimated a multinomial logit model to determine if subsidy rate changes were associated with the likelihood of LRP policies being purchased at different coverage levels.
Findings
After the 2019 and 2020 subsidy rate changes, the likelihood of producers buying LRP-feeder cattle policies with coverage over 95% increased relative to the policies with coverage less than 89.99% but did not influence the likelihood of producers buying LRP-feeder cattle policies with coverage between 90 and 94.99% relative to policies with coverage less than 89.99%. Marginal effects show these subsidy rate changes increased the likelihood of buyers purchasing LRP-feeder cattle policies with greater than 95% coverage. The subsidy change did not affect the purchase of LRP-fed cattle policies.
Originality/value
The results demonstrate the influence of the recent LRP policy adjustments on insurance purchases, which could be important for agency officials and policy makers. This is the first study to explore the LRP policy purchases which provides the United States cattle industry insight into the LRP price insurance take-up, which can guide producer extension education on managing price risk.

Abstract
Purpose
Powder bed fusion processes are common due to their ability to build complex components without the need for complex tooling. While additive manufacturing has gained increased interest in industry, academia and government, flaws are often still generated during the deposition process. Many flaws can be avoided through careful processing parameter selections including laser power, hatch spacing, spot size and shielding gas flow rate. The purpose of this paper is to study the effect of shielding gas flow on vapor plume behavior and on final deposition quality. The goal is to understand more fully how each parameter affects the plume and deposition process.
Design/methodology/approach
A filtered-photodiode based sensor was mounted onto a commercial EOS M280 machine to observed plume emissions. Three sets of single tracks were printed, each with one of three gas flow rates (nominal, 75% nominal and 50% nominal). Each set contained single-track beads deposited atop printed pedestals to ensure a steady-state, representative build environment. Each track had a set power and speed combination which covered the typical range of processing parameters. After deposition, coupons were cross-sectioned and bead width and depth were measured. Finally, bead geometry was compared to optical emissions originating in the plume.
Findings
The results show that decreasing gas flow rate, increasing laser power or increasing scan speed led to increased optical emissions. Furthermore, decreasing the gas cross-flow speed led to wider and shallower melt pools.
Originality/value
To the best of the authors’ knowledge, this paper is among the first to present a relationship among laser parameters (laser power, scan speed), gas flow speed, plume emissions and bead geometry using high-speed in situ data in a commercial machine. This study proposes that scattering and attenuation from the plume are responsible for deviations in physical geometry.

Abstract
Purpose
Drawing on theories of organisational identity, social exchange and stakeholder engagement, this study aims to investigate the processes and practices involved in the formation and shaping of identities of social enterprises (SEs) that operate in the Malawian hospitality and tourism industry.
Design/methodology/approach
Drawing on an interpretive research paradigm, data collected from 22 semi-structured interviews with four founders of case SEs and stakeholders, and SEs’ reports and other publicly available documents were generated and analysed following a grounded theory approach.
Findings
The authors show that the trajectory SEs followed and the exchanges that occurred with the external stakeholders allowed three out of four case SEs to swiftly re-evaluate their pre-existing identities and work towards the formation of their new identities.
Practical implications
This study provides an opportunity for policymakers and other actors in developing countries to frame and place SEs in line with the wider societal realities in such contexts. This may in turn call for policymakers to increase actors’ engagement with SEs and provide the necessary support that can allow SEs to be an effective force for the public good.
Originality/value
This paper highlights the role of exchanges with external stakeholders in identity formation and shaping within SEs in the hospitality and tourism sector in the context of institutional voids. By adopting the social exchange theory, this paper introduces a dynamic lens to identity formation and shaping and helps to explain how, across different tourism ventures, stakeholder engagement and different modes of exchange unfold in the inter-organisational and community domains. It further shows how the ventures’ value orientations on the one hand, and stakeholder engagement practices and the ensuing exchanges, on the other hand, are closely interwoven.
