AbstractThe growth and physiology of soil microorganisms, which play vital roles in biogeochemical cycling, are likely dependent on current and prior soil moisture levels. Here, we developed and applied a genome-resolved metagenomic implementation of quantitative stable isotope probing (qSIP) to an H218O labeling experiment to determine which microbial community members, and with what capacities, are growing under in situ conditions. qSIP enabled measurement of taxon-specific growth because isotopic incorporation into microbial DNA requires production of new genome copies. We studied three Mediterranean grassland soils across a rainfall gradient to evaluate the hypothesis that historic precipitation levels are an important factor controlling trait selection. We used qSIP-informed genome-resolved metagenomics to resolve an active subset of soil community members and identify the ecophysiological traits that characterize them. Higher year-round precipitation levels correlated with higher activity and growth rates of flagellar motile microorganisms. In addition to bacteria that were heavily isotopically labeled, we identified abundant isotope-labeled phages suggesting phage-induced cell lysis likely contributed to necromass production at all three sites. Further, there was a positive correlation between phage activity and the activity of putative phage hosts. Contrary to our expectations, the capabilities to decompose the diverse complex carbohydrates common in soil necromass or oxidize methanol and carbon monoxide were broadly distributed across active and inactive bacteria in all three soils, implying that these traits are not highly selected for by historical precipitation.
The impact of message framing on travellers’ behavioural intentions towards green hotels
Authors: Nimri Rawan , Patiar Anoop , Jin Xin 
Published: May 2022

Purpose
Research in consumer behaviour in the pro-environmental hospitality domain is limited. Furthermore, the efficiency of interventions using pictorial elements, with positive and negative framing, to influence travellers' intentions (INTs) to book green accommodation remains scarcely investigated. The theory of planned behaviour (TPB) offers a platform for testing interventions that could impact consumer behaviour. This study aims to introduce a TPB pictorial intervention in green accommodation and to provide a robust assessment of the intervention targeted at the TPB's factors.

Design/methodology/approach
The data were collected from Australian travellers who were exposed to convincing messages through pictorial elements. These featured either positive or negative pro-environmental effects of hotel operations. A usable sample size of 771 respondents has been achieved. A multi-group analysis using structural equation modelling was performed to investigate the intervention effect.

Findings
The results highlighted the supremacy of positive framing to influence travellers’ INTs regarding patronage of green accommodation. A knowledge-based approach to promoting green practices might encourage travellers to book green accommodations.

Originality/value
This study advances theory building in environmental communication. Subsequently, hoteliers might enhance their marketing strategies to publicise their pro-environmental programs.
Becoming top global chef: what does it take to become a highly successful entrepreneurial careerist?
Authors: Elbasha Tamim , Baruch Yehuda 
Published: May 2022

PurposeThis study aims to understand the career path to the pinnacle of professional life. What does it take for an entrepreneur to become a global celebrity in one’s profession? The authors explore the career motivation, trajectory and outcomes of a niche population who made it to the top of their careers.Design/methodology/approachA qualitative method was applied, using publicly available, prerecorded interviews of a documentary series on a unique sample of 30 top global chefs who gain Michelin-stars or equivalent. The authors used a qualitative approach to analyze the data alternating data and theory.FindingsThe authors identify a unique pattern, which the authors label as the “two-steps” trajectory, where these successful chefs went through a dual-hurdle process: first, delving into formal training and establishing themselves; then moving to a top chef status through innovation inspired by their history, chance events and treating their work as an artistic oeuvre and an experience.Practical implicationsThe authors provide an observed pattern for what is required to be a top global chef.Originality/valueThis study advances career theory and entrepreneurship studies via integrating the two perspectives. The authors offer a theoretical contribution by identifying the relevance and importance of “new careers” for entrepreneurs, recognizing critical success factors and reinstating the balance between the agency of the entrepreneur and their context.
Re-examining oil price-stock market returns nexus in Nigeria using a two-stage Markov regime switching approach
Authors: Raifu Isiaka Akande , Oshota Sebil Olalekan 
Published: May 2022

PurposeIt has been said that oil price shocks affect stock market returns. However, empirical studies remain inconclusive regarding the nexus between oil price shocks and stock market returns. Consequently, the purpose of this study is to investigate the asymmetric impact of oil price shocks on stock returns in Nigeria.Design/methodology/approachA two-stage Markov regime-switching approach is used to examine the asymmetric effects of three different structural oil shocks on stock returns. The oil shocks, which include oil supply shock, aggregate demand shock and oil-specific demand shock, are derived using structural vector autoregressive. Monthly data that spans the period between January 1990 and December 2018 are deployed for estimation.FindingsThe linear estimation results show that only oil demand shock negatively and significantly affects the stock market returns. The Markov-switching regime results reveal that oil supply shock has a significant positive impact on the stock returns in a low-volatility state, whereas oil-specific demand shock negatively impacts the stock returns in a high-volatility state.Practical implicationsThere is a need for policymakers and investors to take cognizance of not only the positive outcomes of a relatively stable state of oil price but also the negative consequences of a high-volatility state when formulating policy and making investment decisions, respectively.Originality/valueThis study differs from other similar studies in Nigeria that have examined the asymmetric relationship between oil price shocks and stock market return by using a two-stage Markov regime-switching approach. To the best of the authors’ knowledge, this is the first attempt at using this methodology.
Transportation service level impact on aircraft availability
Authors: McLean Vincent , Reiman Adam D. 
Published: May 2022

PurposeAircraft fail to meet mission capable rate goals due to a lack of supply of aircraft parts in inventory where the aircraft breaks. This triggers an order at the repair location. To maximize mission capable rate, the time from order to delivery needs to be minimized. The purpose of this research is to examine the case of three airfields for the order to delivery time of mission critical aircraft parts for a specific aircraft type.Design/methodology/approachThis research captured data from three information systems to assess the order fulfillment process. The data were analyzed to determine the performance in fiscal year 2020. Using the model of that performance, the cost of reducing transportation times using publicly available commercial cost estimates was assessed against the impact on aircraft availability.FindingsThe results indicate that paying the costs for expedited shipping would have increased aircraft availability by 1.09 times the average annual aircraft flying hours for the three cases. The cost for the equivalent of an additional aircraft for the year was a third of the annual straight-line depreciation for that aircraft type.Research limitations/implicationsThis research assumed that the transportation time service levels publicly posted could be achieved. The weight of each mission critical part was not available, so the weight was selected from a probability distribution of mission critical part weights that was retrieved from prior research. This research provides options to enhance aircraft availability and identifies the associated costs.Practical implicationsAdjusting the contract with transportation providers to reduce the transportation times of mission critical parts could have a large impact on aircraft availability at relatively little cost.Social implicationsThis research could enhance aircraft readiness in service of the common defense.Originality/valueThis research provides an effective methodology for enhancing military readiness through contract adjustments with commercial partners. The value of this research is that it will serve to adjust the value proposition of mission critical parts inside the United States Transportation Command’s Next Generation Delivery Service contract.

Literature was interpreted based on the search of the researcher on key concepts of the topic.FindingsLiterature indicates new trends in cataloguing and how technologies could be incorporated into cataloguing.Practical implicationsThis study can inform policies on artificial intelligence adoption in cataloguing.Originality/valueThe 4IR and artificial intelligence does not often occur in cataloguing literature. Linking 4IR and advanced technologies, artificial intelligence and robotic science in cataloguing could inform policies and practice in cataloguing.
Effect of alloy particle size and stencil aperture shape on solder printing quality
Authors: Mohamed Sunar Mohamad Solehin , Abu Bakar Maria , Jalar Azman , Ramli Mohamad Riduwan , Che Ani Fakhrozi 
Published: May 2022

Purpose
Reflow solder joint quality is significantly affected by the ability of the solder to perfectly fill pad space and retain good solder joint shape. This study aims to investigate solder joint quality by quantitatively analyzing the stencil printing-deposited solder volume, solder height and solder coverage area.

Design/methodology/approach
The dispensability of different solder paste types on printed circuit board (PCB) pads using different stencil aperture shapes was evaluated. Lead-free Type 4 (20–38 µm particle size) and Type 5 (15–25 µm particle size) solder pastes were used to create solder joints according to standard reflow soldering.

Findings
The results show that the stencil aperture shape greatly affects the solder joint quality as compared with the type of solder paste. These investigations allow the development of new strategies for solving solder paste stencil printing issues and evaluating the quality of solder joints.

Originality/value
The reflow soldering process requires the appropriate selection of the stencil aperture shape according to the PCB and the solder paste according to the particle-size distribution of the solder alloy powder. However, there are scarce studies on the effects of stencil aperture shape and the solder alloy particle size on the solder paste space-filling ability.

Published: May 2022

Purpose
Identifying and analyzing aspects related to sustainable human resources (HRs) in an emerging, Iberoamerican location (Monterrey, Mexico). Documenting employee experiences regarding sustainable practices of HR in their companies to understand the enacted meaning of sustainable HR management (HRM). This study aims to seek answers to understand the ways environmental sustainability is present in HR subprocesses and the ways companies regard HRs from a sustainability perspective.

Design/methodology/approach
This exploratory research has a qualitative approach. The authors collected and summarized semi-structured interviews with 31 key informants that work fully or partially in HRs in a large, industrialized city in an Iberoamerican, emerging economy (Monterrey, Mexico).

Findings
The main findings based on responses from HR professionals are as follows: HR activities may contribute to the sustainability of the business and its physical environment; HR can create a culture of care for the resources, but training and development activities are not currently used optimally; and in addition to the economic sustainability of the employers, social and environmental sustainability are also within HR’s influence sphere.

Originality/value
This study contributes to the emerging literature on sustainability in HRM, due the dearth of information related to “green” or environmental practices in HRM. This study reports specifically on the ways this perspective adds value within Mexican enterprises, but the authors are confident that these findings also generalize across industries, enterprises and regions.
Financial innovation and the stability of money demand in Nigeria
Authors: Ujunwa Augustine , Onah Emmanuel , Ujunwa Angela Ifeanyi , Okoyeuzu Chinwe R , Kalu Ebere Ume 
Published: May 2022

AbstractStudies that explore the relationship between financial innovation and the stability of money demand in Africa use the indirect measure of financial innovation. Previous studies on Nigeria also ignored total monetary aggregates (M3), despite its importance to monetary policy formulation and liquidity management. This paper contributes to the existing literature in two ways; first, we expand the generic money demand function to include the direct measure of financial innovation. Second, we test the model on Nigeria using a broader definition of money demand—narrow money (M1), broad money (M2) and total monetary aggregates (M3). We employ the Pesaran et al. (2001) autoregressive distributed lag (ARDL) bounds test approach to cointegration in estimating the respective equations and find evidence of a long‐run relationship between money demand and financial innovation. The CUSUM and CUSUM‐of‐Squares tests reveal stable money demand across the three measures of money demand, which indicates that the inclusion of financial innovation has not altered the long‐run stability of money demand in Nigeria.
Refugees are a Valuable but Overlooked Economic Resource, and it is Time to Update Our Approach to Migration
Authors: Baker Sally , Cousins Stephanie , Higgins Claire , Tani Massimiliano 
Published: May 2022

AbstractThe view that welcoming refugees represents a cost to a country's welfare services has become anachronistic; nowadays refugees are increasingly recognised for their high levels of education and skills, and their ability to make an economic contribution to a host country. Yet, most states' approach to migration management prevents displaced people from migrating based on the human capital that they can supply. Australia is trialling a new approach that enables refugees to access skilled migration through employer sponsorship. This article describes the pilot project and suggests ways to encourage employers to view refugees as a valuable solution to workforce shortages.
Absence in technicolour: protesting enforced disappearances in northern Sri Lanka
Authors: Buthpitiya Vindhya 
Published: May 2022

AbstractThis essay examines the political uses of photography in the protests of the Tamil families of the disappeared in northern Sri Lanka. Enforced disappearances have long featured as an instrument of state terror. Their lingering effects have been noted as a significant challenge to transitional justice processes in the aftermath of the island's civil war. By examining how protesters make their political demands and grievances known through photography, I explore the tensions between visibility and surveillance. The competing photographies of the protests subvert conceptual understandings of the medium as an ideological tool, but also complicate claims of its capacities for enabling emancipation. Against a backdrop of ethno‐nationalist conflict, this mobilization of and through photography serves as a defiant articulation of post‐war ‘irreconciliation’. It is further tethered to a global visual vernacular of civilian resistance challenging state atrocity, as well as irreconcilable assertions of nation and state.
Evaluation of a national database of completed investigations into radiology service complaints in New Zealand: What can the radiologist, and radiology service providers, learn?
Authors: Ruppeldt Philip , Baker Mike , Wheeler Luke D 
Published: May 2022

AbstractIntroductionThe Health and Disability Commissioner (HDC) is responsible for dealing with most complaints from service users resulting from their interactions with a healthcare service provider in New Zealand. We analysed all published reports involving a radiologist or radiology service in order to gain insights that might promote safer working across the radiology community.MethodsWe searched the entire HDC online report database choosing a limit of ‘radiologist’ as occupation.ResultsTwenty‐seven investigations were included, published between 1999 and 2021. Seventeen (63%) involved private radiology providers and 10 (37%) involved public providers. Ultrasound featured in 12 cases (44%), x‐ray 6 (22%), CT 5 (19%), mammography 2 (7%), MRI 1 (4%) and interventional 1 (4%). Obstetric ultrasound accounted for 9 (75%) of the ultrasound cases. In 24 (89%) cases, the HDC felt an error had been made. Of the 34 radiologists investigated, 21 (62%) were found in breach of the HDC code, with adverse comment made regarding 4 (12%). A total of 46 incidences of different error types were identified including: communication 14 (30%), perceptual 11 (24%), technical 8 (17%) and interpretative 7 (15%). Forty‐five incidences of contributing factors were identified, including organizational 9 (20%) and clinical information provided 7 (16%).ConclusionErrors in radiology practice, leading to complaints, are often multifactorial and systemic. Reflection on the myriad of error types and contributing factors (including ‘human factors’) is imperative to reduce errors. Multifaceted strategies are likely required for radiologists to enhance their systems and practice.

AbstractIntroductionImmune checkpoint inhibitor (ICI) therapy is an established treatment for advanced non‐small‐cell lung cancer (NSCLC) and programmed death ligand‐1 (PD‐L1) expression is a recognized biomarker to determine response to therapy. We retrospectively analyzed NSCLC patients in the Malaysia Lung Cancer Registry (MLCR) and report on the clinical characteristics associated with PD‐L1 expression and ICI use in Malaysia, a low‐ to middle‐income country.MethodsAll 901 NSCLC patients in the MLCR who were diagnosed from January 1, 2017 to December 31, 2020 from 14 hospitals across the country were analyzed.ResultsOut of 901 patients, 505 had PDL‐1 testing done with complete data available only in 489 patients. The most common histology was adenocarcinoma (84.7%) followed by squamous cell carcinoma (10.2%). The majority (95%) presented with stage 3 or 4. The number and percentage of patients with PDL‐1 tumor proportion scores of ≥50%, 1–49%, and <1% were 138 (28.2%), 158 (32.3%), and 193 (39.5%), respectively. In multivariate analysis, the presence of genomic mutation is the only independent characteristic associated with negative PD‐L1 expression (crude odds ratio 0.579, 95% confidence interval 0.399–0.840, p = 0.004). Of 292 patients eligible for ICI therapy, only 100 patients (34.2%) received ICIs. Seventy‐eight patients received ICI therapy as first‐line treatment, 15 patients as second‐line treatment, and 7 patients as third‐line treatment.ConclusionsThis is the first analysis on PD‐L1 expression and ICI use in Malaysia. Despite the proven efficacy of ICI therapy, only 56% of our patients had PD‐L1 tests performed and only 34.2% of eligible patients received ICIs.
Root and canal morphology of the maxillary second premolars as indicated by cone beam computed tomography
Authors: Olczak Katarzyna , Pawlicka Halina , Szymański Witold 
Published: May 2022

AbstractThe aim was to evaluate the morphology of maxillary second premolars. The root canal configurations were classified according to Vertucci and a new system by Ahmed et al. based on CBCT images. In addition, the number of roots and the level where they bifurcated were identified, and morphological measurements were performed based on anatomical landmarks. Single‐rooted forms were most common. Bifurcation occurred most often in the middle part of the root. The most common canal configuration was type I according to Vertucci and code 1SP1 according to the new classification. The measurements showing the results were as follows (mm): palatal cusp/buccal cusp/the lowest point of the occlusal surface to pulp chamber ceiling 6.18/6.54/4.77; the ceiling of the pulp chamber was found at the CEJ in 92.28% of the specimens. The maxillary second premolars tended to be single‐rooted and with one root canal.

Published: May 2022

AbstractThis study used secondary data from the My Teaching Partner‐Math/Science 2013–2016 randomized control trial to explore whether equitable sociocultural classroom interactions (see Curenton et al., 2019) were associated with the skills of 105 four‐ and five‐year‐olds (52% boys; drawn from 20 unique video recordings of preschool teachers/classrooms; 43% were Black, Latine, Asian, or other racially marginalized learners). Equitable interactions predicted children's skills with effect sizes ranging from small (0.01–0.44) to large (1.00). Moderation analyses revealed that when classrooms had more racially marginalized learners, teachers’ use of equitable disciplinary and personalized learning practices were associated with higher executive functioning gains across prekindergarten. Findings illustrate how classroom composition can be a key indicator between equitable classroom interactions and young children's early skills.
