Authors: Singh Aishwarya , Sharma Swati , Sengupta Santoshi , Goel Kavita 
Published: April 2023

Purpose
Responding to the radical changes in work practices and extensive virtual forms of interaction brought by COVID-19, this study aims to investigate the role played by authentic leadership and horizontal collectivism in helping the Indian startups sail through the pandemic.

Design/methodology/approach
Data was gathered through standardized questionnaires from 300 leaders and 300 employees from Indian startups during the second phase of lockdown. Statistical analysis using AMOS 23.0 checks for the direct effect of authentic leadership on work engagement and the moderating effect of horizontal collectivism on the relationship between the two. This study also compares the results between self-ascribed and perceived authentic leadership.

Findings
Statistical analysis using AMOS 23.0 was done to check for the direct effect of authentic leadership on work engagement and the moderating effect of horizontal collectivism on the relationship between authentic leadership and work engagement. This study also compared the results between self-ascribed and perceived authentic leadership.

Originality/value
To the best of the authors’ knowledge, this is the first study that explores the role of authentic leadership in unlocking work engagement among employees serving in Indian startups during the pandemic. The lesson learned from this is when employees perceived their leaders to be authentic, the work culture to be nonhierarchical and felt collective responsibility toward work, it unlocked their high potential and made them soulfully engaged in their work.

Published: April 2023

PurposeGripped by the COVID-19 pandemic, the airline industry has faced many restrictions. Based on the determining factor of repurchase intention, this research paper addresses the roles of brand engagement (BE) and consumer trust during the pandemic.Design/methodology/approachA number of 439 out of 500 questionnaires, which were distributed among the Iranian airlines' customers, were completed and returned (an 87% response rate). SmartPLS 3 was used to carry out the confirmatory factor analysis (CFA) and exploratory factor analysis (EFA) in order to validate the research hypotheses.FindingsThe results show that during the COVID-19 pandemic, BE had a significant effect on customer purchase intention. In addition, BE boosted customer trust and thereby increased repurchase intention. Perceived risks of COVID-19 moderated these relationships. The findings also show that airline customers are highly sensitive to various perceived risks and were especially so during the COVID-19 pandemic. These perceived risks have major impacts on customers' intention to reuse the services of airline companies. High levels of perceived risk decrease customer trust, BE and repurchase intention rates, and vice versa.Practical implicationsThis paper provides authorities and decision-makers of the air transport industry with several practical recommendations based on the research findings. As the results confirmed, there is a worthwhile relationship between BE and customer trust; regarding the both direct and indirect benefits of customer trust for for-profit firms and the huge importance of trust in creating competitive advantages, different airline companies need to implement various strategies to engage customers with their brand names, and thereby institutionalize trust in their customers' minds during the pandemic. Since customer trust was also found to improve repurchase intention rates significantly, authorities of the airline industry must take actions to reduce feelings of mistrust and risk among consumers and increase customer trust during COVID-19.Originality/valueThis paper is the first to explore the effect of BE on airline customers' repurchase intentions during the COVID-19 pandemic. It has produced practical suggestions to employees and activists of the air transport industry regarding the use of BE as a tool to restore customer trust during and after the COVID-19 epidemic. This research focuses on the airline industry, which is particularly interesting given the industry's intensely competitive environment and the dramatic effect of COVID-19 on the industry.
Where economics and management connect: Courcelle-Seneuil as a pioneer of scientific management
Authors: Barbieri Fabio , Rossi Mazzoni João Fernando 
Published: April 2023

Purpose
The purpose of this paper is to discuss the pioneering work of the 19th-century French author Jean-Gustave Courcelle-Seneuil in developing a scientific perspective on management, whose origin is commonly associated with the contributions of Frederick Taylor and Henri Fayol.

Design/methodology/approach
Through a historical analytical approach and doing a parallel analysis with the origins of the economic theory, fragments of two works by Jean-Gustave Courcelle-Seneuil (1813–1892) are analyzed: The Theoretical and Practical Treatise on Industrial, Commercial and Agricultural Enterprises: A Business Manual (1855) and Ergonomics, the second part of the book Theoretical and Practical Treatise on Political Economy (1858), in which the author devotes a chapter to relevant aspects of management, such as entrepreneurship, production, human resources, finance and accounting.

Findings
In addition to noting the pioneering character of these contributions, particularly the emphasis on entrepreneurship, Courcelle-Seneuil’s argument favors in the 19th century a scientific approach to management, contradicting the belief of businesspeople of the time, according to whom management was something practical, impossible to be studied analytically.

Research limitations/implications
This study indicates that looking to the past is essential to know what has already been produced in a particular field of knowledge. This return to the origins is fundamental to understanding how science evolves. Although management as a systematized field of expertise is usually dated to the beginning of the 20th century, there are reasons to expand on the influences that gave rise to this science, particularly regarding lesser-known but equally important contributions.

Originality/value
This study explores a lesser-known contribution to the origin of management theory and seeks to contribute to the study of the origin of the division of the fields of management science, its roots and its intersection with the economic science practiced in the half of the 19th century.
Beyond sharing knowledge: knowledge brokers’ strategies to build capacity in education systems
Authors: Caduff Anita , Lockton Marie , Daly Alan J. , Rehm Martin 
Published: April 2023

PurposeThe study analyzes how equity-focused knowledge brokers, working at different levels of the US education system, understand and discuss capacity building in education systems, such as schools, districts, state and local education agencies, to answer this research question: How do equity-focused knowledge brokers support capacity building in education systems?Design/methodology/approachSemi-structured interviews were conducted with five well-known equity-focused organizations that broker evidence-based knowledge and resources to educational systems, practitioners and policymakers. The research team members qualitatively analyzed 18 h of recordings, using their co-developed codebook based on the research questions and prior research on knowledge mobilization.FindingsFour strategies to build capacity within the educational systems were identified. Pursuing sustainable educational change, brokering organizations built capacity with context-specific strategies: (1) engaging various roles within educational systems, (2) fostering communities and partnerships, (3) supporting educators and policymakers’ agency and efficacy and (4) creating a wider culture of external support beyond the systems themselves.Originality/valueThis study shows how knowledge brokers employed context-specific strategies targeting whole systems instead of individuals to ensure that the organization and individuals within had the mindsets, capability, and conditions to engage with and adapt the brokered knowledge and resources. Findings build on existing literature showing how knowledge brokers build capacity through well-known approaches, such as workshops/training, online tutorials and other online resources.
Twitter and the circular economy: examining the public discourse
Authors: Mastroeni Loretta , Naldi Maurizio , Vellucci Pierluigi 
Published: April 2023

PurposeThough the circular economy (CE) is a current buzzword, this still lacks a precise definition. In the absence of a clear notion of what that term includes, actions taken by the government and companies may not be well informed. In particular, those actions need to consider what people mean when people talk about the CE, either to refocus people's decisions or to undertake a more effective communications strategy.Design/methodology/approachSince people voice people's opinions mainly through social media nowadays, special attention has to be paid to discussions on those media. In this paper, the authors focus on Twitter as a popular social platform to deliver one's thoughts quickly and fast. The authors' research aim is to get the perceptions of people about the CE. After collecting more than 100,000 tweets over 16 weeks, the authors analyse those tweets to understand the public discussion about the CE. The authors conduct a frequency analysis of the most recurring words, including the words' association with other words in the same context and categorise them into a set of topics.FindingsThe authors show that the discussion focuses on the usage of resources and materials that heavily endanger sustainability, i.e. carbon and plastic and the harmful habit of wasting. On the other hand, the two most common good practices associated with the CE and sustainability emerge as recycling and reuse (the latter being mentioned far less). Also, the business side of the CE appears to be relevant.Research limitations/implicationsThe outcome of this analysis can drive suitable communication strategies by which companies and governments interested in the development of the CE can understand what is actually discussed on social media and call for the attention.Originality/valueThis paper addresses the lack of a standard definition the authors highlighted in the Introduction. The results confirm that people understand CE by looking both at CE's constituent activities and CE's expected consequences, namely the reduction of waste, the transition to a green economy free of plastic and other pollutants and the improvement of the world climate.
A tiny cuckoo: Risk‐dependent interspecific brood parasitism in a predatory mite
Authors: Choh Yasuyuki , Janssen Arne 
Published: April 2023

Abstract

Many animal species protect their eggs against predators, and other species may profit from this by adding their eggs to those of the protecting species.

We studied two tiny species of predatory mites that share a food source, are engaged in intraguild predation, and which eggs are attacked by the same egg predator.

One of these predatory mites (Neoseiulus californicus) adds its eggs to those of the other species (Gynaeseius liturivorus) which guards its eggs from egg predators, resulting in reduced predation of the eggs of the nonguarding species. The guarding species experiences costs in the form of intraguild predation of her offspring, and the addition of eggs to the guarding species therefore qualifies as brood parasitism.

In the presence of egg predators, the brood parasite preferentially adds its eggs to those of the guarding host species, not to those of another, nonguarding mite species.

This cuckoo behaviour comes with a cost for the parasite when egg predators are absent, and therefore only occurs when egg predators are present.

Our findings emphasize the importance of the risk of egg predation as a factor driving facultative brood parasitism.

Published: April 2023

Policy PointsSocial indicators of young peoples’ conditions and circumstances, such as high school graduation, food insecurity, and smoking, are improving even as subjective indicators of mental health and well‐being have been worsening. This divergence suggests policies targeting the social indicators may not have improved overall mental health and well‐being.There are several plausible reasons for this seeming contradiction. Available data suggest the culpability of one or several common exposures poorly captured by existing social indicators.Resolving this disconnect requires significant investments in population‐level data systems to support a more holistic, child‐centric, and up‐to‐date understanding of young people's lives.
Measuring emergency physician productivity and work patterns
Authors: Freeman Peter 
Published: April 2023

AbstractI propose a methodology to compare individual emergency physician (EP) work patterns. This is intended to generate discussion within the specialty. A work pattern graph shows individual EP productivity and, assuming the EPs case selection is similar, can be used to compare group activity. Using a simple mathematical model, an averaged calculation can be made of the number of patients needed to be seen by each treating clinician during a standard shift.

Published: April 2023

AbstractIn terrestrial ecosystems, the activities of semi‐fossorial animals such as Cape porcupines have important landscape effects that may manifest in the dry season when the availability of above‐ground forage becomes limiting. We investigated the effects of foraging activities of Cape porcupines on savanna landscapes. We measured the size (surface area and depth) of foraging holes of porcupines located at the base of trees in the dry season in two mesic savanna sites at Roodeplaat Farm and Bisley Valley Nature Reserve in South Africa. We also recorded plant and animal activities inside the foraging holes for 3 months. The depth of foraging holes beneath small trees (Vachellia nilotica) was greater than depths beneath old trees (V. robustaandD. rotundifolia). This resulted in the subsequent death of most (>50%) small impacted trees in the dry season at Bisley. The surface area of foraging holes for older trees was greater than that for small trees and even greater for old holes. This study showed that porcupines kill trees or expose them to secondary attacks. The physical impacts of semi‐fossorial herbivores in savannas can be significant, with contributions to direct and indirect landscape transformation and restoration.

AbstractObjectivesTo estimate the prevalence of, and risk factors associated with electrode migration (EM) in cochlear implant (CI) recipients.DesignHistorical cohort study of all CIs performed between 1 January 2018 and 1 August 2021 in a single tertiary adult and paediatric CI centre in the UK.Main Outcome MeasuresThe primary aim is to determine the prevalence of electrode migration, comparing intraoperative surgeon report and examination of a routine plain radiograph performed 2 weeks after surgery. EM is defined as the detection of movement of two or more electrodes out of the cochlea from the time of surgery. Multivariate analysis was performed to investigate preoperative and intraoperative risk factors that might predispose to migration.ResultsFour hundred and sixty‐five patients, having 516 distinct surgeries, with 628 implants were analysed. EM occurred following 11.5% of implant operations. Pre‐existing cochlear abnormality was an independent associated risk factor for EM (OR: 3.40 ⟨1.20–9.62⟩ p = .021). Demographics, surgical technique, usage of a precurved electrode, CSF leak, surgeon seniority and intraoperative telemetry did not influence risk of migration. There were 5 implants (0.8%) which migrated later than 2 weeks, with a median date of imaging diagnosis (x‐ray or CT scan) of 263 days ⟨IQR:198⟩, for which head injury was a common precipitating factor. There were differences in the risk of migration between different lateral wall electrodes.ConclusionEM in the early postoperative period is a common occurrence and is more likely in implant recipients with obstructed or malformed cochleae.

AbstractAimsInsulin action in the brain influences cognitive processes, peripheral metabolism and eating behaviour. However, the influence of age and peripheral insulin sensitivity on brain insulin action remains unclear.Materials and MethodsWe used intranasal administration of insulin and functional magnetic resonance imaging in a randomized, placebo‐controlled within‐subject design in 110 participants (54 women, body mass index 18‐49 kg/m2, age 21‐74 years). Cerebral blood flow was measured before and after nasal spray application to assess brain insulin action. Peripheral insulin sensitivity was assessed by a five‐point oral glucose tolerance test. Linear regressions were used to investigate associations between age and peripheral insulin sensitivity with brain insulin action in predefined region of interests (i.e. insulin‐sensitive brain regions).ResultsWe found significant negative associations between age and insulin action in the hippocampus (β = –0.215; p = .017) and caudate nucleus (β = –0.184; p = .047); and between peripheral insulin sensitivity and insulin action in the amygdala (β = –0.190, p = .023). Insulin action in the insular cortex showed an interaction effect between age and peripheral insulin sensitivity (β = –0.219 p = .005). Furthermore, women showed the strongest negative association between age and hippocampal insulin action, while men showed the strongest associations with peripheral insulin sensitivity and age in reward‐related brain regions.ConclusionWe could show a region‐specific relationship between brain insulin responsiveness, age and peripheral insulin sensitivity. Our findings underline the need to study brain insulin action in both men and women and further substantiate that brain insulin sensitivity is a possible link between systemic metabolism and neurocognitive functions.
Rural market imperfections in India: Revisiting old debates with new evidence
Authors: Sekhar C. S. C. , Thapa Namrata 
Published: April 2023

SummaryMotivationEnsuring viability of farming and increasing farmers' incomes are key policy concerns in India at present. To realize these aims, markets need to function well: market imperfections can increase production and transaction costs for farmers and thereby reduce incomes. A longstanding and repeated observation in India is that land productivity is inversely related to farm size, an inverse relation (IR) which may well indicate imperfectly functioning land, labour, and credit markets.PurposeThe study revisits the inverse relation, to examine whether market imperfections still prevail in India, particularly in output, input, factor, and credit markets.Methods and approachBased on multi‐stage sampling, 1,800 households spread over 45 villages and 21 districts were surveyed across Bihar, Gujarat, Madhya Pradesh, and Punjab. Micro‐econometric methods were applied to the household‐level data to test for relations between farm size and land and labour productivity, and implied evidence of market imperfections.FindingsA strong IR between land productivity and farm size on the output side, and farm size and family labour use on the input side can be seen. However, intensive use of family labour on small farms is not the only determinant of farm size‐productivity relations. It is found that smaller farmers are relatively more constrained in obtaining credit. The results suggest that Sen's labour dualism theory, together with imperfections in land and credit markets, offers important insights. Also, drawing from the recent literature, measurement errors in plot size and production and “edge effect” could be some of the contributing factors.Policy implicationsOur findings point to the prevalence of surplus family labour on small farms, even a decade after the enactment of a major employment guarantee programme (MGNREGS), exacerbated by small farmers having limited access to institutional credit.Thus, particularly for marginal and small farmers, reforming land lease markets to enable easier access to land, providing better access to institutional credit, and improving literacy to enable farmers to deploy abundant household labour in other occupations, are needed to address some of the observed imperfections.

Published: April 2023

SummaryWhole wheat bread is poor in quality, and it is necessary to use certain methods to improve bread texture and glycaemic index, such as adding exogenous protein. This study evaluated the effects of adding different proportions of gluten (focus on exogenous protein enrichment) on dough structure, bread quality, and starch digestibility, focusing on mixing properties, rheological properties, pasting properties, microstructure, basic quality, and starch digestibility. Dough microstructure results showed that gluten addition helped to form a more complete gluten network. The bread quality results showed that gluten‐enriched bread had larger specific volume, lower baking loss, and better textural quality. Starch digestibility results showed that gluten addition slowed down starch digestion to some extent. The experimental results indicated that 40% added gluten could produce bread samples with optimal quality. The subject systematically studied the effect of gluten enrichment on the quality of whole wheat bread, which is a guide to the application.
