PurposeThe primary objective of this investigation is to optimize the constricted arc tungsten inert gas (CA-TIG) welding parameters specifically welding current (WC), arc constriction current (ACC), ACC frequency (ACCF) and CA traverse speed to maximize the tensile properties of thin Inconel 718 sheets (2 mm thick) using a statistical technique of response surface methodology and desirability function for gas turbine engine applications.Design/methodology/approachThe four factor – five level central composite design (4 × 5 – CCD) matrix pertaining to the minimum number of experiments was chosen in this investigation for designing the experimental matrix. The techniques of numerical and graphical optimization were used to find the optimal conditions of CA-TIG welding parameters.FindingsThe thin sheets of Inconel 718 (2 mm thick) can be welded successfully using CA-TIG welding process without any defects. The joints welded using optimized conditions of CA-TIG welding parameters showed maximum of 99.20%, 94.45% and 73.5% of base metal tensile strength, yield strength and elongation.Originality/valueThe joints made using optimized CA-TIG welding parameters disclosed 99.20% joint efficiency which is comparatively 20%–30% superior than conventional TIG welding process and comparable to costly electron beam welding and laser beam welding processes. The parametric mathematical equations were designed to predict the tensile properties of Inconel 718 joints accurately with a confidence level of 95% and less than 4.5% error. The mathematical relationships were also developed to predict the tensile properties of joints from the grain size (secondary dendritic arm spacing-SDAS) of fusion zone microstructure.

Published: January 2022

Purpose
Aeromedical training is meant to train aircrew in combating physiological problems that they might face in flight. Given the importance of the training, there are limited studies in the literature investigating the anxiety levels during aeromedical training along with training outcomes. This study aims to assess the untrained participants’ anxiety levels before and after aeromedical training, investigate the differences in anxiety levels across different physiological training devices and determine whether participants’ anxiety levels affect their G tolerances.

Design/methodology/approach
This study was carried out on 61 healthy male subjects (n = 61) who had applied for initial aeromedical training. Anxiety surveys and visual analog scales were administered before and after the practical aeromedical training. In addition, blood pressure and heart rate measurements were carried out.

Findings
Participants had significantly higher anxiety levels before human centrifuge training (pre-Glab) than before the altitude chamber training (pre-hypobaric). Participants who experienced G-induced loss of consciousness (G-LOC) had slightly more anxiety reported than the non-G-LOC group. There was a significant decrease between pre-Glab and post-Glab (after the human centrifuge training) and between pre-hypobaric and post-hypobaric (after the altitude chamber training) anxiety levels. The incidence of G-LOC was lower in participants having higher pre-G-Lab blood pressure. However, the difference in anxiety levels between the G-LOC group and the non-G-LOC group was not statistically significant.

Research limitations/implications
In this study, state anxiety inventory was not performed after human centrifuge training as centrifuge training lasted for around 5 min only, and it is not advisable to repeat state anxiety inventory in such short periods. Blood pressure was not measured after G-Lab training because human centrifuge training is hard training and has an impact on blood pressure. Hence, it would have been difficult to distinguish whether the blood pressure change was due to anxiety or hard physical activity. These limitations, especially for the G-Lab, caused us to evaluate state anxiety only with VAS. It would be worthwhile to repeat similar studies with objective measurements before and after the training.

Practical implications
This information suggests that instructors who train the applicants on aerospace medicine be ready for the possible consequences of anxiety.

Originality/value
There are only a few centers in the world that include all the physiological training devices (practical aeromedical training laboratories) together. To the best of authors’ knowledge, there are no studies in the literature investigating the differences in anxiety levels across various physiological training devices. The studies about the effect of anxiety levels on aeromedical training outcomes and anxiety levels before and after the training are scant.
Sustainability and authenticity: are they food risk relievers during the COVID-19 pandemic?
Authors: Marozzo Veronica , Meleddu Marta , Abbate Tindara 
Published: January 2022

PurposeThe study jointly investigates sustainability and authenticity concepts in the food context during the COVID-19 outbreak with a fourfold objective: (1) understanding whether sustainability and authenticity are equivalent concepts in consumers' perceptions; (2) advancing knowledge on the role played by them about food frauds' perception; (3) investigating whether these concepts are considered as “risk relievers” by consumers, (4) comparing the concepts to understand which one has a greater weight on the consumer's perception.Design/methodology/approachThe study adopts a Combination of a Uniform and a shifted Binomial distribution (CUB models) on data gathered in Spain between June and August 2020 through an online questionnaire.FindingsThe findings reveal that: (1) consumers perceive sustainability and authenticity as different concepts in the food context and (2) as two important indicators of fraud protection of a product for consumers; (3) besides, authenticity is seen as a “risk reliever” in buying a food product, as well as sustainability, (4) although results underline high uncertainty in the latter case.Originality/valueBy considering that the COVID-19 outbreak seriously threatens food safety, security and nutrition, this research elucidates the relevant role of food sustainability and authenticity concepts as “risk relievers” in terms of food frauds and negative issues related to COVID-19.
Generating, weaving and curating: disciplinary processes for reading literary text
Authors: Reynolds Todd , Rush Leslie S. , Holschuh Jodi Patrick , Lampi Jodi P. 
Published: January 2022

PurposeThe purposes of this study is to expand on previous work in English language arts (ELA) disciplinary literacy and to unpack literary text reading processes across three different participant groups.Design/methodology/approachThe authors recruited literary scholars and first-year college students to read literary texts aloud and voice their thoughts. Transcripts were collaboratively coded and analyzed usinga prioriand emergent coding.FindingsThis study presents the findings in two ways. First, this study grouped the codes into four categories, namely, background knowledge, comprehension, disciplinary knowledge and building an interpretation. This described the differences in frequencies among the participants’ strategy use. Next, to more fully describe how participants read literary texts, this study presents the data using three processes, namely, generating, weaving and curating. These findings indicate a continuum of strategies and processes used by participants.Practical implicationsThe study suggests using the ELA heuristic for instruction, which includes moving students beyond generating and weaving by asking them to do their own interpretive work of curation. This potential roadmap for instruction avoids a deficit mindset for students by recommending low-stakes opportunities that meet students where they are as they build their capacity for interpretive moves.Originality/valueThe findings help the field to gain an understanding of what novices and experts do when they read literary text, including both strategies and processes. This study also provide an ELA heuristic that has instructional implications. This study adds to the body of knowledge for disciplinary literacy in ELA in both theoretical and practical ways.
Effect of cutting parameters on tool life during end milling of AISI 4340 under MQL condition
Authors: Ahmad Ahsana Aqilah , Ghani Jaharah A. , Che Haron Che Hassan 
Published: January 2022

Purpose
The purpose of this paper is to study the cutting performance of high-speed regime end milling of AISI 4340 by investigating the tool life and wear mechanism of steel using the minimum quantity lubrication (MQL) technique to deliver the cutting fluid.

Design/methodology/approach
The experiments were designed using Taguchi L9 orthogonal array with the parameters chosen: cutting speed (between 300 and 400 m/min), feed rate (between 0.15 and 0.3 mm/tooth), axial depth of cut (between 0.5 and 0.7 mm) and radial depth of cut (between 0.3 and 0.7 mm). Toolmaker microscope, optical microscope and Hitachi SU3500 Variable Pressure Scanning Electron Microscope used to measure tool wear progression and wear mechanism.

Findings
Cutting speed 65.36%, radial depth of cut 24.06% and feed rate 6.28% are the cutting parameters that contribute the most to the rate of tool life. The study of the tool wear mechanism revealed that the oxide layer was observed during lower and high cutting speeds. The former provides a cushion of the protective layer while later reduce the surface hardness of the coated tool

Originality/value
A high-speed regime is usually carried out in dry conditions which can shorten the tool life and accelerate the tool wear. Thus, this research is important as it investigates how the use of MQL and cutting parameters can prolong the usage of tool life and at the same time to achieve a sustainable manufacturing process.

Authors: Maile Edward John , Mitra Mahima , Ovseiko Pavel , Dopson Sue 
Published: January 2022

Purpose Hospital mergers are common in the United Kingdom and internationally. However, mergers rarely achieve their intended benefits and are often damaging. This study builds on existing literature by presenting a case study evaluating a merger of two hospitals in Oxford, United Kingdom with three distinct characteristics: merger between two university hospitals, merger between a generalist and specialist hospital and merger between two hospitals of differing size. In doing so, the study draws practical lessons for other healthcare organisations.Design/methodology/approach Mixed-methods single-case evaluation. Qualitative data from 19 individual interviews and three focus groups were analysed thematically, using constant comparison to synthesise and interpret findings. Qualitative data were triangulated with quantitative clinical and financial data. To maximise research value, the study was co-created with practitioners.Findings The merger was a relative success with mixed improvement in clinical performance and strong improvement in financial and organisational performance. The merged organisation received an improved inspection rating, became debt-free and achieved Foundation Trust status. The study draws six lessons relating to the contingencies that can make mergers a success: (1) Develop a strong clinical rationale, (2) Communicate the change strategy widely and early, (3) Increase engagement and collaboration at all levels, (4) Be transparent and realistic about the costs and benefits, (5) Be sensitive to the feelings of the other organisation and (6) Integrate different organizational cultures effectively.Originality/value This case study provides empirical evidence on the outcome of merger in a university hospital setting. Despite the relatively positive outcome, there is no strong evidence that the benefits could not have been achieved without merger. Given that mergers remain prevalent worldwide, the practical lessons might be useful for other healthcare organisations considering merger.

Authors: Hussain Khalil , Abbasi Amir Zaib , Rasoolimanesh S. Mostafa , Schultz Carsten D. , Ting Ding Hooi , Ali Faizan 
Published: January 2022

PurposeThe local food tourism in Pakistan is increasing rapidly, and it attracts scholars to determine the factors affecting local food tourists' buying choices. Particularly, the authors aim to investigate the role of food consumption values on predicting domestic tourists' attitude toward local food and its effect on the intention to try local food with the moderating effect of personality traits (neophobia and neophilia).Design/methodology/approachThe authors tested the study model on 250 completed responses from local food tourists. They collected the data from three tourism locations (Islamabad, Rawalpindi and Peshawar) in Pakistan. Their study utilizes the consumption value theory within the limits of Pakistan's local food tourism.FindingsThe empirical findings show that consumption values, such as price, emotion, interaction, epistemic value, location value and variety value, effectively explain the domestic tourists' attitude toward local food. The authors further report that food neophilia strengthens the local tourists' positive reception toward the local food. However, food neophobia weakens the direction between local tourists' attitude toward local food and the intention to try local food.Practical implicationsThis study provides insights pertaining to tourists' local food consumption values (LFCVs) to a local destination owner and marketing manager to strategically work on LFCVs that are crucial for domestic tourists to derive their intention to try local food. Practitioners should work on domestic tourists who possess food neophobia trait and enquire them for their rejection or avoidance of a particular local destination. This will enable practitioners to bring innovation and development in the local destination, which ultimately promote local food tourism.Originality/valueThis study is the first to incorporate the variety and local value in tourists' LFCVs to predict local tourists' attitude toward local food. Additionally, the authors contribute to local food tourism by empirically studying the moderating role of personality traits (food neophilia and food neophobia) to examine the direction between local tourists' attitude and intention to local food.
The centrality of organisational factors in the growth of new technology-based firms
Authors: Tarillon Caroline 
Published: January 2022

PurposeNew technology-based firms (NTBFs) are a great potential source of job creation and economic growth. In France, strong heterogeneity of their growth trajectories is observed yet many of them remain small. A better understanding of these trajectories is thus necessary. The purpose of this paper is to explore the influence of individual and organisational factors on 253 growth trajectories of NTBFs.Design/methodology/approachThe authors use a Heckman ordered probit model to study explanatory factors of growth trajectories in NTBFs created between 1999 and 2012. This method allows them to study the determinants of the presence of a growth dynamics at the same time as the determinants of growth intensity.FindingsThe model shows that entrepreneurs play a weak role in understanding the growth trajectories of their company. Rather, it is organisational factors – such as the level of innovation and the governance structure – that explain initiation of a growth trajectory and the intensity of the growth.Originality/valueBy using an original methodology, the authors highlight the importance of organisational factors and encourage entrepreneurs to develop a governance structure focused on internal stakeholders to support growth.
Digital preservation of information sources at academic libraries in Jordan: an employee’s perspective
Authors: Awamleh Manal Ahmad , Hamad Faten 
Published: January 2022

Purpose Digital preservation requires new skills and collaboration among library staff to maintain long-term access to information resources. Digital content and digital technologies pose a serious challenge to information institutions to continue to select, preserve and access information resources. However, there is an urgent need to increase awareness of the new trends in the partnership between research communities and academic libraries; there is also a need for new digital preservation-related skills among librarians. Therefore, this research aims to investigate the benefits, importance, requirements and challenges of digital preservation in academic libraries in Jordan.Design/methodology/approach A questionnaire was disseminated to 150 library staff working at the 10 public universities in Jordan, with 133 questionnaires suitable to analyze with a response rate of (88.6%).Findings The results indicate a moderate perception of the benefits and importance of digital preservation, as well as the requirements and challenges in academic libraries in Jordan to carry out the digital preservation process. This indicated the importance of increasing the academic libraries' – specifically academic libraries in Jordan – awareness of the vast and important benefits of digital preservation to maintain long-term access to information. It was noted that factors such as sex, experience, educational level and specialization did not affect the results.Practical implications The findings will provide insights for other academic libraries on how to plan and develop preservation policies to maintain access to information.Social implications Access to information is a human right that contributes to the advocacy of sustainable development, and hence, digital preservation can facilitate long-term availability and accessibility to information.Originality/value This paper provides insights and practical solutions for academic libraries in response to technological development and the change requirements. It will help academic libraries handle and cope with the challenges of providing distance library services over digital channels.
Recordkeeping culture in Switzerland: the impact of language and communication on the success of recordkeeping initiatives
Authors: Frings-Hessami Viviane , Oliver Gillian 
Published: January 2022

Purpose
Records management has been heavily influenced by practice in English-speaking countries but is often seen as a foreign import in non-Anglophone countries. This study aims to investigate how using English terminology or translating records management terminology into French in a Francophone environment impacts on the success of recordkeeping strategies.

Design/methodology/approach
Semi-structured interviews were conducted with Francophone archivists and records managers in Switzerland to assess their communication strategies and the language used to communicate recordkeeping objectives.

Findings
The research findings indicate that in a Francophone environment, archivists and records managers who use French terminology are more successful in promoting recordkeeping objectives than those who use English terminology. Given that research was limited to one Swiss canton, more research is needed to test these findings in other Francophone cantons, provinces and countries.

Originality/value
This study is important for the success of recordkeeping initiatives in non-Anglophone countries. It highlights the need to take into account the local information culture and use terminology with which people are most familiar.
On the build orientation effect in as-printed and as-sintered bending properties of 17-4PH alloy fabricated by metal fused filament fabrication
Authors: Suwanpreecha Chanun , Manonukul Anchalee 
Published: January 2022

Purpose
The purpose of this paper is to systematically investigate the influence of build orientation on the anisotropic as-printed and as-sintered bending properties of 17-4PH stainless steel fabricated by metal fused filament fabrication (MFFF).

Design/methodology/approach
The bending properties of 17-4PH alloy fabricated by low-cost additive manufacturing (MFFF) using three build orientations (the Flat, On-edge and Upright orientations) are examined at both as-printed and as-sintered states.

Findings
Unlike tensile testing where the Flat and On-edge orientations provide similar as-sintered tensile properties, the On-edge orientation produces a significantly higher bending strain with a lower bending strength than the Flat orientation. This arises from the printed layer sliding due to the Poisson's effect, which is only observed in the On-edge orientation together with the alternated layers of highly deformed and shifted voids. The bending properties show that the Upright orientation exhibits the lowest bending properties and limited plasticity due to the layer delamination.

Originality/value
This study is the first work to study the effect of build orientation on the flexural properties for MFFF. This work gives insight information into anisotropy in flexural mode for MFFF part design.
Structural process model of absorptive capacity for stakeholder’s integration in decision-making: dynamic capability perspective
Authors: Bhupendra Kumar Verma , Sangle Shirish 
Published: January 2022

PurposeThis paper aims to present empirical test to analyse a structural process model based on the constructs of absorptive capacity considering sustainability aspects. It integrates dynamic capability perspective to strengthen the existing literature. Findings of the study may help organisations to renovate business processes related to absorptive capacity and improve decision-making considering sustainability attributes.Design/methodology/approachSample for data analysis covers 389 managers of firms demonstrating some traits of sustainability orientation and operating in a developing economy like India. Structural equation modelling is applied to test a casual model.FindingsResult of this study reveals that a formal system that drives knowledge sharing, storing and exploitation of knowledge, a structured way to appropriate and reward intellectual property rights can be fundamental to development of absorptive capacity. Such a system conducive to knowledge exploration and acquisition must lead to exploration of new knowledge sources and new knowledge. A firm’s knowledge acquisition system shall be able to deliver to acquire external as well as internal knowledge spread across departments.Research limitations/implicationsThis study considers commercial output as an aspect of innovative capability, so this attribute is not included in absorptive capacity.Practical implicationsThe study may help organisations to develop a systemic approach to evolve decision-making and develop suitable processes linked to absorptive capacity considering sustainability challenges and uncertain market conditions.Social implicationsThe study presents a comprehensive view of absorptive capacity considering societal stakeholder’s knowledge in addition to technological and market knowledge.Originality/valueThere are hardly any research articles which link absorptive capacity, dynamic capability and sustainability strategies.
