Leadership and stewardship in public procurement: roles and responsibilities, skills and abilities
Authors: Steinfeld Joshua M. 
Published: February 2022

Purpose
The purpose of this paper is to identify the roles and responsibilities most important to public procurement practitioners to learn about procurement’s influence in the public management setting. Also, the skills and abilities associated with these roles and responsibilities are identified and discussed to implicate the strategic orientations of practitioner work and the skills and abilities that support these endeavors.

Design/methodology/approach
The 2020 National Institute of Governmental Purchasing (NIGP) survey is used as a method of primary data collection and analysis. Factor analyses are run to yield relationships between the roles and responsibilities in public procurement to determine what it is that public practitioners value the most in their work, as well as to control for skills and abilities, to implicate the ways in which these roles and responsibilities are approached from a strategic perspective.

Findings
The results demonstrate that public procurement roles and responsibilities do not easily fit into any one category of public management, and that qualitative factors in public procurement are rated to be more important than quantitative factors. Additionally, the skills and abilities deemed to be most important in completing these roles and responsibilities implicate qualitative traits such as building trust and credibility, effective communications and relationship management.

Social implications
The study demonstrates that although public procurement practitioners view the socio-economic roles and responsibilities to be most important, such as in creating a culture of continuous improvement, developing a thriving workplace, supporting an ethical workplace and providing professional development opportunities, that public procurement falls short because the actual implementation of social and environmentally sustainable policies and fostering of an ethical professional culture are not viewed to be important by practitioners. The study offers leadership and stewardship as an approach to combat this lack of follow-through by public procurement departments.

Originality/value
This study provides exclusive access to the 2020 NIGP study and, to the best of the author’s knowledge, is the first research of its kind to highlight the roles and responsibilities, skills and abilities viewed to be most important by public procurement practitioners. Additionally, the link between skills and abilities, and roles and responsibilities is discussed to implicate leadership and stewardship in the strategic orientations of public procurement.
Human enhancement technologies and the future of consumer well-being
Authors: Lima Vitor , Belk Russell 
Published: February 2022

Purpose
The purpose of this paper is to propose a conceptual framework that highlights transhumanism’s ideals of achieving superintelligence, super longevity and super well-being through human enhancement technologies (HET) and their relations with services marketing principles.

Design/methodology/approach
Framed by the transformative service research (TSR), this conceptual work articulates the 7Ps of the marketing mix with four macro-factors that create tensions at both the marketplace and consumer levels.

Findings
HET has potential for doing good but also tremendous bad; greater attention is needed from services marketing researchers especially in one proprietary research area: bioethics.

Research limitations/implications
The authors contribute to the growing work on TSR investigating how the interplay between service providers and consumers affects the well-being of both. Additionally, the authors call for novel interdisciplinary work in transhuman services research.

Originality/value
To the best of the authors’ knowledge, this is one of the first papers in services marketing research to explore the promises and perils of transhumanism ideals and human enhancement technologies.
Students' perceptions of augmented reality integrated into a mobile learning environment
Authors: Li Mingchao , Liu Liping 
Published: February 2022

PurposeThis study was based on situated learning, by combining mobile learning and augmented reality, so that students could not only access information content in a real environment but also obtain such information via augmented reality, to support mobile learning.Design/methodology/approachThe research included development of an augmented reality system combined with situational learning, used by students to learn about campus plants as part of the college life technology curriculum. Students took part in mobile learning, and an investigation was conducted into the computer learning behaviour of notebook users. College students were used as the experimental subjects. Data were collected using questionnaire surveys and were evaluated in order to identify the behavioural intentions of learners in outdoor learning activities.FindingsThe questionnaire survey covered environmental interactivity, system quality and textbook content. It was found that learners who used mobile learning augmented reality (MLAR) generally managed to browse all the contents of the textbook at each learning location, without spending too much time looking for information, and learners could quickly integrate this into the learning situation. Learners who used MLAR had a strong motivation to study plants at the learning site because they wanted to use the augmented reality technology to observe virtual plant models. Learners who used MLAR in their field learning liked using augmented reality for further learning, for example, using a magic wand to interact with the technology.Originality/valueThis study adopted a new approach to deliver elements of the life technology curriculum, integrating augmented reality into mobile learning. All participating students gave positive reviews of six aspects of the proposed system: their behavioural intentions, cognitive usefulness, cognitive ease of use, environmental interactivity, system quality and textbook content.

Published: February 2022

Purpose
This paper aims to investigation of processes for Pb2+ elimination from water/wastewater as a significant public health issue in many parts of world. The removal of Pb2+ ions by various nanocomposites has been explained from water/wastewaters. ZnO-based nanocomposites, as eco-friendly nanoparticles with unique physicochemical properties, have received increased attention to remove Pb2+ ions from water/wastewaters.

Design/methodology/approach
In this review, different ZnO-based nanocomposites were reviewed for their application in the removal of Pb2+ ions from the aqueous solution, typically for wastewater treatment using methodology, such as adsorption. This review focused on the ZnO-based nanocomposites for removing Pb2+ ions from water and wastewaters systems.

Findings
The ZnO-based nanocomposite was prepared by different methods, such as electrospinning, hydrothermal/alkali hydrothermal, direct precipitation and polymerization. Depending on the preparation method, various types of ZnO-based nanocomposites like ZnO-metal (Cu/ZnO, ZnO/ZnS, ZnO/Fe), ZnO-nonmetal (PVA/ZnO, Talc/ZnO) and ZnO-metal/nonmetal (ZnO/Na-Y zeolite) were obtained with different morphologies. The effects of operational parameters and adsorption mechanisms were discussed in the review.

Research limitations/implications
The findings may be greatly useful in the application of the ZnO-based nanocomposite in the fields of organic and inorganic pollutants adsorption.

Practical implications
The present study is novel, because it investigated the morphological and structural properties of the synthesized ZnO-based nanocomposite using different methods and studied the capability of green-synthesized ZnO-based nanocomposite to remove Pb2+ ions as water contaminants.

Social implications
The current review can be used for the development of environmental pollution control measures.

Originality/value
This paper reviews the rapidly developing field of nanocomposite technology.
CSR crises from the consumers’ perspective: a multidimensional typology and future research agenda
Authors: Grunwald Guido 
Published: February 2022

PurposeThe purpose of this paper is to develop a multidimensional corporate social responsibility (CSR) crisis typology from the consumers’ perspective and to provide an agenda for future research.Design/methodology/approachBasic content-related dimensions for characterizing CSR crises from the consumers’ perspective are derived from a review of relevant static crisis typologies. Different types of consumer responses to negative CSR information are derived from various theoretical approaches. Dynamic process models of corporate crises are reviewed to assign various types of consumer responses to different crisis phases. Linking both static and dynamic approaches leads to a comprehensive consumer-oriented typology of CSR crises that is illustrated with examples.FindingsA CSR crises typology is developed based on three consumer-related dimensions: the extent to which the company is attributed blame by consumers; the amount of perceived damage potential; and the perceived CSR relevance of the crisis situation. The combination of these dimensions results in eight different crisis types. For each of these crisis types, different forms of consumer responses are assigned that prevail in the so-called potential, latent and manifest crisis phase.Research limitations/implicationsFuture research could address the empirical review of the crisis typology presented, its refinement by considering various consumer and stakeholder segmentation approaches and the advanced dynamic analysis of CSR crises by including stakeholder characteristics that impact the diffusion of CSR-related negative publicity.Practical implicationsThe results of this paper support early crisis detection and effective crisis management by identifying relevant target variables for crisis communication.Originality/valueThe typology developed enables a broad spectrum of CSR crises to be classified, including those that have been neglected in previous systematization approaches, such as CSR-related tensions, general sustainability crises and product-harm crises. Due to its theoretical foundation, this paper also contributes to a clearer demarcation of existing CSR crisis constructs.
Multilevel boundary crossing and dialogical learning mechanisms in interdisciplinary research teams
Authors: Ryymin Essi , Lamberg Laura 
Published: February 2022

Purpose
This paper aims to reveal learning potential in crossing disciplinary boundaries in facilitated workshops by exploring the research goal definition process of interdisciplinary research teams. It uses multilevel boundary crossing as a theoretical framework to illustrate the multilevel nature of team learning mechanisms in interdisciplinary research.

Design/methodology/approach
This study uses a qualitative case study approach. The data was collected from semi-structured interviews and collaborative workshops of interdisciplinary researchers. The data analysis is based on pre-existing theory and the process of analysis is both data and theory driven.

Findings
The results indicate that although defining interdisciplinary research goals is a complex and demanding task, collaborative and facilitated workshops may support boundary crossing on intrapersonal, interpersonal and institutional levels. The team members efforts in defining their shared research interest revealed dialogical learning mechanisms of identification, coordination, reflection and the first phases of transformation, particularly at the interpersonal level. However, the transformative actions seemed to require intentional team facilitation.

Originality/value
This case study enriches the existing literature and allows better understanding of how team facilitation can promote agenda setting, transformative learning mechanisms and the definition of joint research goals in interdisciplinary settings.
Occupational therapy service provision in adult intensive care units in Australia: A survey of workload practices, interventions and barriers
Authors: Rapolthy‐Beck Andrea , Fleming Jennifer , Turpin Merrill 
Published: February 2022

AbstractIntroductionOccupational therapy practice within intensive care units (ICUs) is limited with respect to published research evidence and guidelines regarding scope of practice. An understanding of the current level of service provision, feasibility of services in ICUs and training and development needs of occupational therapists is required to enable consistent best practice and promote the occupational therapy profile. This study aimed to explore occupational therapy practice within ICUs in Australia including the barriers and enablers to practice perceived by occupational therapists.MethodsIn this cross‐sectional study, a national customised online survey was completed by registered occupational therapists who provide services in intensive care settings in Australia. Recruitment was from July to September 2019 through Occupational Therapy Australia and other professional networks and interest groups.ResultsThe survey was completed by 43 respondents. The majority were experienced therapists from Queensland with greater than 10‐years post‐qualification and working in a tertiary hospital setting. The most common length of time spent working in the ICU was 0–2 h per week. Formal and informal self‐care measures, cognitive screens and physical outcome measures were commonly used. Bed‐based grooming retraining, pressure care management, functional upper limb retraining and passive ranging were the most frequent interventions provided on a daily basis. Perceived barriers to occupational therapy service provision in ICU included lack of funding for staffing, competing workload demands, lack of occupational therapy role delineation and scope of practice and lack of published evidence and training.ConclusionOccupational therapy services in intensive care settings in Australia are limited. Published practice guidelines, further research, applications for service funding and ongoing education of the ICU multidisciplinary team regarding the scope of occupational therapy practice are recommended to promote the development of occupational therapy services in ICU.

Published: February 2022

AbstractAligning with Sustainable Development Goal 5, which aims to ‘achieve gender equality and empower all women and girls’, this study examines the impact of board heterogeneity on the sustainability of 794 microfinance institutions in 22 Sub‐Saharan African countries from 2010 to 2018. Using the panel–spatial correlation consistent estimation technique to correct for incidences of cross‐sectional dependence, heteroscedasticity and serial correlation, the findings reveal that gender heterogeneity in the boardroom exerts a positive and significant influence on the sustainability of microfinance institutions in Sub‐Saharan Africa. In addition, factors such as the portfolio quality and the level of corruption in the domiciled countries threaten microfinance sustainability while its total asset base and leverage enhance it. In part, the study suggests that policy discussions on microfinance sustainability should emphasise ensuring increasing participation of women in the boardroom.
Review article: E‐learning in emergency medicine: A systematic review
Authors: Savage Alexander J , McNamara Patrick W , Moncrieff Thomas W , O'Reilly Gerard M 
Published: February 2022

AbstractE‐learning (EL) has been developing as a medical education resource since the arrival of the internet. The COVID‐19 pandemic has minimised clinical exposure for medical trainees and forced educators to use EL to replace traditional learning (TL) resources. The aim of this review was to determine the impact of EL versus TL on emergency medicine (EM) learning outcomes of medical trainees. A systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta‐analysis statement using articles sourced from CINAHL, Embase, OVID Medline and PubMed. Articles were independently reviewed by two reviewers following strict inclusion and exclusion criteria. Bias was assessed using the Cochrane Risk of Bias tool. The search yielded a total of 1586 non‐duplicate studies. A total of 19 studies were included for data extraction. Fifteen of the included studies assessed knowledge gain of participants using multiple‐choice questions as an outcome measure. Eleven of the 15 demonstrated no statistically significant difference while two studies favoured EL with statistical significance and two favoured TL with statistical significance. Six of the included studies assessed practical skill gain of participants. Five of the six demonstrated no statistical significance while one study favoured EL with statistical significance. This systematic review suggests that EL may be comparable to TL for the teaching of EM. The authors encourage the integration of EL as an adjunct to face‐to‐face teaching where possible in EM curricula; however, the overall low quality of evidence precludes definitive conclusions from being drawn.
A transposon‐introduced G‐quadruplex motif is selectively retained and constrained to downregulate CYP321A1

Published: February 2022

AbstractInsects utilize xenobiotic compounds to up‐ and downregulate cytochrome P450 monooxygenases (P450s) involved in detoxification of toxic xenobiotics including phytochemicals and pesticides. G‐quadruplexes (G4)‐forming DNA motifs are enriched in the promoter regions of transcription factors and function as cis‐acting elements to regulate these genes. Whether and how P450s gain and keep G4 DNA motifs to regulate their expression still remain unexplored. Here, we show that CYP321A1, a xenobiotic‐metabolizing P450 from Helicoverpa zea, a polyphagous insect of economic importance, has acquired and preserved a G4 DNA motif by selectively retaining a transposon known as HzIS1‐3 that carries this G4 DNA motif in its promoter region. The HzIS1‐3 G4 DNA motif acts as a silencer to suppress the constitutive and induced expression of CYP321A1 by plant allelochemicals flavone and xanthotoxin through folding into an intramolecular parallel or hybrid‐1 conformation in the absence or presence of K+. The G4 ligand N‐methylmesoporphyrin IX (NMM) strengthens the silencing effect of HzIS1‐3 G4 DNA motif by switching its structure from hybrid‐1 to hybrid‐2. The enrichment of transposons in P450s and other environment‐adaptation genes implies that selective retention of G4 DNA motif‐carrying transposons may be the main evolutionary route for these genes to obtain G4 DNA motifs.
Traumatic irreducible anterior dislocation of the radio‐capitellar joint due to entrapment of the brachialis tendon lateral to the radial head: A case report
Authors: Dimmick Simon , Lin Jiun‐Lih , Linklater James , Sher Doron 
Published: February 2022

AbstractElbow dislocation is the second most common type of joint dislocation in adults and the most common joint dislocation in children. These dislocations are commonly associated with significant soft tissue injury and/or fractures. Anterior dislocation of the radio‐capitellar articulation is uncommon. Failure of relocation of the radial head due to soft tissue imposition requiring open reduction is rare, however, is extremely important to recognise clinically and radiologically. This case report describes a case of anterior dislocation of the radio‐capitellar joint due to entrapment of the brachialis tendon lateral to the radial head and discusses the radiological assessment and the spectrum of causes of a clinically irreducible radio‐capitellar joint. Misdiagnosis of a dislocation or failed reduction may result in long‐term functional sequelae for the patient.
An experimental test of the Coase conjecture: Fairness in dynamic bargaining
Authors: Fanning Jack , Kloosterman Andrew 
Published: February 2022

AbstractWe conduct a novel experimental test of the Coase conjecture based on subjects' privately known preferences for fairness. In an infinite horizon bargaining game, a proposer proposes a division of chips, until a responder accepts. When players are patient, the Coase conjecture predicts almost immediate agreement on equal monetary payoffs given any possibility a responder will not accept anything less. Behavior closely matches theory. In particular, when chips are worth more to proposers than responders, initial offers, minimum acceptable offers, responder payoffs, and efficiency are significantly larger in infinite horizon games than ultimatum games, and proposer payoffs are significantly smaller.

AbstractSpecies occur in sympatric assemblages, bound together by ecological relationships and interspecific interactions. Borneo and Sumatra host some of the richest assemblages of biota worldwide. The region, however, faces the highest global deforestation rates, which seriously threaten its unique biodiversity. We used a large camera trap dataset that recorded data for 70 terrestrial species of mammals and birds, to explore the drivers of regional species richness patterns. Using a multi‐scale, multivariate modelling framework which quantified the main environmental factors associated with patterns of biodiversity, while simultaneously assessing individual relationships of each species, we determined the ecological drivers of sampled biodiversity, and their contributions to community assemblages. We then mapped predicted species richness, evaluated the effectiveness of protected areas in securing biodiversity hotspots, performed gap analysis to highlight biodiverse areas lacking protection and compared our predictions with species richness maps produced by using IUCN range layers. Finally, we investigated the performance of each species as an indicator of sampled biodiversity. We demonstrate that biodiversity in Borneo and Sumatra is primarily affected by gradients of ecological and anthropogenic factors, and only marginally by topographic and spatial factors. In both islands, species are primarily associated with elevational gradients in vegetation and climate, leading to altitudinal zonation in niche separation as a major factor characterizing the islands' biodiversity. Species richness was highest in north‐eastern Borneo and in western Sumatra. We found that most predicted biodiversity hotspots are not formally protected in either island; only 9.2 and 18.2% of the modelled species richness occurred within protected areas in Borneo and Sumatra, respectively. We highlighted that our prediction for Borneo performed better than, and differed drastically from, the IUCN species richness layer, while for Sumatra our modelled species richness layer and the IUCN one were similar, and both showed low predictive power. Our analysis suggests that common and generalist carnivores are the most effective indicators of sampled biodiversity and have high potential as focal, umbrella or indicator species to assist multi‐species vertebrate conservation planning. Understanding existing drivers and patterns of biodiversity is critical to support the development of effective community conservation strategies in this rapidly changing region.
