Countries’ governance and competitiveness: business environment mediating effect
Authors: Bontempo Paulo Cesar 
Published: September 2021

Purpose
The purpose of this study is to analyze how institutional governance and business environment affect countries’ competitiveness and their relative importance.

Design/methodology/approach
In this paper, the authors analyze how institutional governance and business environment affect countries’ competitiveness, their relative importance and what are the implications for Brazil. The authors have collected data from 131 countries related to the institutional governance, business environment and competitiveness of these countries. For the analysis of the mentioned influences, the technique of partial least squares structural equations modeling is used.

Findings
Results indicate that the main role in countries’ competitiveness is played by the quality of institutional governance. The quality of the business environment reinforces the positive effect of the quality of institutional governance on countries’ competitiveness (mediation effect). Brazil has poor governance quality indicators when compared to high-middle income countries, especially regarding government effectiveness, political stability and control of corruption.

Research limitations/implications
The study provides a better understanding of the relative importance of governance quality and business environment quality for countries’ competitiveness. One limitation of this study is that the research was restricted to data related to the year 2019.

Practical implications
For strategists and decision-makers, understanding these effects on countries’ competitiveness and their relative importance is fundamental to understanding what makes their companies internationally competitive.

Social implications
The presence and appreciation of institutional governance quality need to be cultivated in society.

Originality/value
Instead of using the original diamond model, which presents circular relationships, the authors have used the business environment construct, composed of elements of the diamond model to test the relationships between the quality of institutional governance, competitiveness and the business environment.
Recreational scuba diving as a special form of tourism: lessons from Taiwan
Authors: Dai You-De , Huang Fei-Hsin , Chen Kuan-Yang , Chen Wei-Jen , Huan Tzung-Cheng 
Published: September 2021

Purpose
Recreational scuba diving is one of the fastest growing tourism industries around the world and has become a popular activity in Taiwan. Few studies focus on enduring involvement with a high risk or difficult activity specialization, so this study aims to explore the causal relationship between enduring involvement and specialization and seeks to explain sustained involvement in scuba diving activity as a recreation specialization.

Design/methodology/approach
This research selects four diving sites in Taiwan as survey locations, specifically Yeliou, Longdong, Kenting and Green Island. The questionnaire consists of three sections, including demographic information, enduring involvement and specialization. By analyzing the data collected from 810 scuba divers in Taiwan, structural equation modeling is used to examine the causal relationships among the variables.

Findings
The primary findings of this study are as follows: attraction positively affects divers’ commitment and lifestyle through joy, relaxation and sharing diving experiences; the results indicate that self-expression is associated with past experience of participating in scuba diving activity; and centrality indicates that participants’ daily life and recreation are related to each other and become central to their life. Results show that most theoretical hypotheses are supported, but there is no significant evidence of attraction impacting past experience or self-expression influencing commitment and lifestyle.

Originality/value
To the best of the authors’ knowledge, this study is the first to examine the causal influence of enduring involvement and specialization in the scuba diving context. The findings provide a solid theoretical basis for the study of sustained involvement motivation and behavior on specialization. Implications and recommendations for future research are discussed.

Authors: Farooq Rayees 
Published: September 2021

Purpose
The purpose of this study is to offer the bibliometric analysis of the Journal of Knowledge Management (JKM) to understand how the literature has developed over time.

Design/methodology/approach
This study used bibliometric approaches to analyze a sample of 669 studies from 1997 to 2021. This study focused on performance analysis and scientific mapping of articles using the R package.

Findings
The results indicate that the number of publications during the period has significantly increased which shows a growing interest of researchers in the JKM. This study highlights new emerging themes such as change management, change readiness, product innovation and digital libraries which uncover exciting avenues for new research opportunities. USA and UK were the most productive countries in terms of the number of citations followed by few European countries including Spain, Finland, Germany and Sweden. However, it is worth noting that India was the most productive country in the emerging economies.

Practical implications
This study will act as a guide for researchers of various fields to evaluate the development of scientific publications in a particular theme over time, especially for those who are in the field of knowledge management (KM).

Originality/value
This study aims to accomplish the systematic bibliometric analysis of the JKM for more than two decades, providing useful insights into the key developments in the field of KM. This study is more rigorous and comprehensive in terms of the analytical techniques used.
Patterns of pollination interactions at the community level are related to the type and quantity of floral resources
Authors: Fantinato Edy , Sonkoly Judit , Török Péter , Buffa Gabriella 
Published: September 2021

Abstract

A fundamental question in community ecology is how the quantity of floral resources affects pollinator activity and how this relates to the structure and robustness of pollination networks. The issue has been mainly addressed at the species level, while at the community level several questions are still open.

Using a species‐rich semi‐natural grassland as model ecosystem, we explored the relationship between community‐level quantity of floral resources, the number of flower visits at community level and descriptors of the structure and robustness of pollination networks. To assess whether patterns of pollination interactions were consistent when using different types of floral resources, we measured three types of floral resources, namely the volume of nectar, the number of pollen grains and the number of flowers.

Community‐level pollinator visitation rate showed a hump‐shaped relationship with the quantity of floral resources. Results were consistent among models employing different measures of floral resources as independent variables. The relationship between the quantity of floral resources and the structure and robustness of the network was not consistent among different types of floral resources; only intermediate levels of nectar volume were associated with high levels of network robustness.

The pattern we found is in contrast with some former studies which reported positive linear relationships between the community‐level visitation rate of pollinators and the quantity of floral resources. Rather, the observed hump‐shaped pattern resembles the relationship previously found between the quantity of floral resources of a given plant species and its visitation rate per flower. Our results highlighted that, by using specific types of floral resources (e.g. the volume of nectar and the number of pollen grains), it is possible to reveal ecological processes that would be masked by using the number of flowers as the sole measure of floral resource.

Social participation in occupational therapy: Is it possible to establish a consensus?
Authors: da Silva Ana Cristina Cardoso , Oliver Fátima Corrêa 
Published: September 2021

AbstractBackgroundSocial participation has been incorporated by occupational therapists in Brazil, and worldwide, as a professional concept to guide practice. The concept has been studied, defined, and constructed from multiple fields of knowledge and can be defined as the social and political involvement of people in social groups and /or public and community spaces. There are different understandings of social participation in occupational therapy and the objective of this study was to explore how Brazilian occupational therapists define social participation in their fields of knowledge.MethodThrough application of the Delphi technique, Brazilian occupational therapy academics and professionals who have worked in the state of São Paulo, Brazil, collaboratively responded to an online questionnaire. In the consultation phase, occupational therapists wrote their conceptions about social participation and, in the consensus phase, expressed their opinions and judgements, in order to, in a collective construction, establish a consensus on the definition of social participation.ResultsIn the first round of the consensus phase, 38 academics and 27 professionals participated and in the second round, 20 and 14, respectively. Results were analysed quantitatively, through the establishment of degrees of agreement for conceptions arranged in statements. Then, six categories of analysis were built, which identified the multiple ways of understanding social participation: social participation and social interactions, social participation and freedom of movement, social participation as an experience in public and political life, social participation and human activities, social participation and the process of social inclusion, and social participation in the fields of knowledge and practice in occupational therapy.ConclusionThere are theoretical‐conceptual differences in the understandings and uses of social participation in occupational therapy that delimit specificity and design the identities of the profession in society. The need to discuss knowledge production, accumulation, and dissemination and practices is debated.
Airbnb and micro‐entrepreneurship in regional economies: Lessons from Australia
Authors: Mahmuda Sirat , Sigler Thomas , Corcoran Jonathan , Knight Eric 
Published: September 2021

AbstractHaving begun as a short‐term rental platform in major cities, Airbnb has now extended to many remote and regional areas of Australia. One effect of this spread has been disruption to the conventional rental industry, which stimulates micro‐entrepreneurship in local communities directly through short‐term accommodation and indirectly through related industries. Given Australia’s core–periphery settlement structure, resulting from the country’s historical development, disruption through entrepreneurship has relatively more potential in remote and regional areas. This article uses the Porter diamond model to explain how Airbnb‐led micro‐entrepreneurship interacts with territorially embedded socioeconomic characteristics across regional and remote Australia. Drawing on Airbnb data for Australia between 2014 and 2018 at the scale of regional labour markets, we use a quantile regression model to explain the association between Airbnb‐led micro‐entrepreneurship and four distinct structural dimensions between metropolitan and non‐metropolitan regions. The analysis provides evidence that non‐metropolitan regions have certain stronger competitive advantages for attracting Airbnb‐led micro‐entrepreneurship compared with metropolitan regions, particularly across regional cities and in areas associated with mining, agriculture, and tourism. We conclude that policymakers should weigh concerns relating to peer‐to‐peer accommodation in major metropolitan regions against the purported benefits to peripheral regions.

Published: September 2021

AbstractPerilla seed oil (PSO) has a special aromatic odor, which is unpleasant to the personal preferences of some consumers. To this end, this article evaluated the differences in volatile organic compounds (VOCs), physicochemical characteristics, and fatty acid composition of PSO treated with ethanol (PSO‐EA), activated carbon (PSO‐AC), and activated kaolin (PSO‐AK). The results showed that in the PSO, PSO‐EA, PSO‐AC, and PSO‐AK samples, the content of linolenic acid, oleic acid, and linoleic acid hardly changed. Among the physicochemical characteristics of the four samples, the color difference between PSO and PSO‐EA was greater than the color difference between PSO and PSO‐AC, PSO‐AK. The three treatment methods had the greatest impact on the PSO peroxide value but had little effect on other indicators. Gas chromatography–ion mobility spectrum results identified 28 known volatiles, of which aldehydes, alkenals, alcohols, ketones, and esters were the main groups. Fingerprint analysis found that PSO had an aromatic odor, which includes 1‐hexanol, hexanal, and 2‐pentylfuran; the removal effect of ethanol on VOCs in PSO was better than that of activated carbon and activated kaolin. The difference between the four oil samples was found from the strength of the VOCs’ signals in a two‐dimensional map. From the principal components analysis and the “nearest neighbor” fingerprint analysis, it was found that PSO is generally quite different from PSO‐EA, PSO‐AC, and PSO‐AK, while in the “nearest neighbor” fingerprint analysis, PSO‐AC and PSO‐AK are similar in general. In short, PSO will have better applications in the food field.Practical ApplicationTreatment of PSO with ethanol, activated carbon, and activated kaolin is conducive to the comprehensive utilization of edible resources. In this work, ethanol, activated carbon, and activated kaolin were used to remove VOCs in PSO, and PSO‐EA, PSO‐AC, and PSO‐AK were obtained. The perilla seed oil after these three treatment methods was tested for VOCs, physicochemical characteristics, and fatty acid composition. They can meet the needs of more consumers without affecting the fatty acid composition in the PSO, and have broad development prospects.
Should farmers farm more? Comparing marginal products within Malawian households
Authors: Brummund Peter , Merfeld Joshua D. 
Published: September 2021

AbstractAccording to standard economic theory, households should equate the marginal revenue product of an input across activities within the household. However, this prediction may not hold in the presence of risk. Using data on farm plots and non‐farm enterprises in Malawi, we examine the impact of risk on the allocation decisions of agricultural households as they allocate labor across farm and non‐farm production. We control for many household and production characteristics, including household fixed effects, and find farm marginal revenue product of labor (MRPL) to be consistently higher than non‐farm MRPL. These results are consistent with farm production being riskier than non‐farm production for most households in Malawi. These findings suggest that improved access to insurance of farming activities and wage employment opportunities could increase total household income.

AbstractObjectiveTo evaluate the utility and outcomes for Indigenous and non‐Indigenous patients requiring domiciliary oxygen therapy.DesignRetrospective study.SettingPatients residing in the regional and rural Top End Health Service region of the Northern Territory of Australia.ParticipantsIndigenous and non‐Indigenous patients prescribed domiciliary oxygen therapy between 2018 and 2020.InterventionsDemographics and clinical indication for domiciliary oxygen therapy and mortality were analysed.Main outcome measuresDifferences between Indigenous patients requiring domiciliary oxygen therapy in comparison with their non‐Indigenous counterparts.ResultsOf the 199 study participants, the majority were male (51%), non‐Indigenous (77%) and urban residents (72%). Overall chronic obstructive pulmonary disease was the most common indication for domiciliary oxygen therapy (51%) followed by palliative intent (22%). Indigenous patients were significantly younger (61 vs 73 years), with a higher proportion of males (62% vs 45%, P = .039) and remote residents (62% vs 8%, P < .001). Among Indigenous patients, a significantly greater proportion of domiciliary oxygen therapy was indicated for chronic obstructive pulmonary disease and bronchiectasis (16% vs 1%, P < .001). Among non‐Indigenous patients, malignancies were a more common indication for domiciliary oxygen therapy. A similar proportion of Indigenous and non‐Indigenous patients were prescribed domiciliary oxygen therapy for palliative intent (31% and 20%, P = .108); however, the underlying diagnosis differed significantly, with a greater proportion of chronic obstructive pulmonary disease among Indigenous patients (43% vs 13%, P = .030) and malignancy among the non‐Indigenous patients (73% vs 43%, P = .050). Mortality and length of survival were not significantly different by Indigenous status. Linear regression showed longer survival with domiciliary oxygen therapy for chronic obstructive pulmonary disease.ConclusionIndigenous Australian patients living in remote communities will likely derive the same benefits and outcomes of domiciliary oxygen therapy as non‐Indigenous peers.

Published: September 2021

AbstractBackgroundPancreatic ductal adenocarcinoma (PDAC) patients with diabetes mellitus (DM) have poor overall survival. Underlying mechanisms have not been fully clarified. This presents an opportunity for precision‐oncology for which we systematically analysed publicly‐available PDAC transcriptome data.MethodsPDAC TCGA RNASeq data were used. Analyses were restricted to only ‘high purity’ and ‘head’ as anatomical site. Patients were characterised by: (1) Gene expression classification, and (2) Weighted gene correlation network analysis (WGCNA) to identify co‐expression patterns of genes. Newly identified gene signature subclasses of pancreatic head PDAC were associated with clinical and functional characteristics of patients.ResultsConsensus clustering identified two patient subclasses within PDAC involving pancreatic head. WGCNA identified 11 distinct networks of gene expression patterns across two sub‐classes. Class 1 patients demonstrated a significant upregulation of Module 5 and Module 6 gene expression compared to Class 2. Class 1 predominantly expressed the acinar, ductal and islet cell gene signatures. There were significantly less patients with DM in Class 1 subclass compared to Class 2 (p < 0.037). Patients with DM had significant downregulation of pathways involved in cellular metabolism, hormone secretion and paucity of islet cell markers with no reduced survival compared with non‐diabetics.ConclusionsA significant proportion of patients with PDAC of pancreatic head and DM exhibit downregulation of pathways involved in cellular metabolism, hormone secretion and signalling accompanied by a paucity of islet expression. Investigating the relationship between DM and gene expression profiles in patients with PDAC presents opportunities to improve overall survival in diabetics with PDAC.
Video feedback combined with coordination meetings in school to reduce early disruptive behaviour problems (DBP)—A 1‐year follow‐up randomised controlled trial

Published: September 2021

AbstractAimTo compare long‐term effects of a systemic school‐based intervention, Marte Meo and Coordination Meetings (MAC), targeting 3‐ to 12‐year‐old children displaying disruptive behaviour problems (DBP) in preschool or school, and service as usual (SAU). In addition, to examine whether social status (SS) affected the outcomes.MethodsIn a randomised controlled design, teachers' and parents' ratings of 99 children's DBPs and mental health were collected before intervention and 1 year after post‐test.ResultsA significant time effect in school was found in both interventions, notably larger than at post‐test in an earlier study. There was no difference between groups, SAU catching up with MAC. From teachers' reports, 53–70% of the children showed a positive change. SS did not affect the outcomes.ConclusionSchool provides an already established setting to detect and intervene when young children begin to display DBP. Even if a long‐term positive change in MAC did show more rapidly than in SAU, both interventions were equivalent for children from diverse social backgrounds.

AbstractIntroductionRobot‐assisted radical prostatectomy (RARP) is nowadays being performed worldwide, and inguinal hernia (IH) continues to be a common complication of radical prostatectomy. Laparoscopic repair of IH is often difficult via internal dissection because of adhesion of the preperitoneal cavity. This study aimed to categorize the intraoperative condition of, and devise a strategy for, IH after RARP.MethodsOf 577 patients who underwent RARP, 18 developed IH. These 18 patients then underwent laparoscopic IH repair using the transabdominal preperitoneal approach (TAPP) or modified intraperitoneal onlay mesh repair (mIPOM). Internal dissection was categorized into two groups according to the appearance of Cooper's ligament (exposed or not exposed).ResultsAfter RARP, four patients had exposure of Cooper's ligament while 14 patients showed no exposure. Both patients in the exposed group underwent TAPP and all patients in the not‐exposed group underwent mIPOM. There was no significant difference between normal TAPP and RARP regarding operative factors, and IH recurrence was not observed.ConclusionLaparoscopic repair of IH after RARP is rendered safe and efficient by using our categorization based on the exposure of Cooper's ligament and extension of preperitoneal space.
