Innovation from sport's entrepreneurship and intrapreneurship: opportunities from a systematic review
Authors: Lara-Bocanegra Alejandro , Bohórquez M. Rocío , García-Fernández Jerónimo 
Published: May 2021

PurposeThe main aim of this study was to analyze and establish the state of the question about entrepreneurship and intrapreneurship in sport, identify the role of innovation in both of them, as well as to determine the latest study trends and detect possible research niches.Design/methodology/approachA systematic review of the Web of Science, Scopus, PsycINFO, ERIC, SPORTDiscus and Dialnet databases was performed. The analysis of the selected texts allowed categorizing the entrepreneurship articles into subthemes: precursors of entrepreneurship, intention/orientation of entrepreneurship, different perspectives of entrepreneurship in sport and social entrepreneurship in sport. Of the 49 texts included in the review, only seven articles dealt with intrapreneurship, and they could not be classified into subtopics because the studies are scarce, diverse and with disparate themes.FindingsThe main findings show deficiencies in research on precursors/antecedents of entrepreneurial and intrapreneurial behavior, especially in relation to innovation, the importance of the political perspective on entrepreneurship in sport and formulation of behavior training programs for intrapreneurs.Originality/valueThis paper provides valuable and global information about entrepreneurship and intrapreneurship in sport, of which there were scattered or grouped data in some reviews.
Stakeholder views on sustainability in an urban destination context: an inclusive path to destination competitiveness
Authors: Panse Gaurav , Fyall Alan , Alvarez Sergio 
Published: May 2021

Purpose
Mass tourism in urban settings has proven to be economically significant in many parts of the world. To date, however, the academic debate on sustainable tourism has focused primarily on the ecological and socio-cultural sustainability of tourism in rural and coastal, rather than urban, settings. This paper aims to review the emerging debate on sustainable urban tourism, its complexities and challenges, and questions how urban destinations that are striving to become sustainable cities, can leverage benefit from the implementation of sustainable policies and practices to achieve tourism ‘destination’ competitiveness.

Design/methodology/approach
The paper uses a qualitative, exploratory research approach using in-depth interviews to seek responses from key stakeholders on their views and experiences of sustainability in the context of an urban destination. Thematic analysis is used to analyze and present the findings.

Findings
This study concludes that destinations need to be viewed in their broader regional context. Rather than be viewed solely as destinations that are ‘kind to the environment,’ sustainable urban destinations need to demonstrate a deeper commitment to all stakeholder groups, and especially local residents, to provide a fair and desirable ecosystem for achievement of the UN Sustainable Development Goals.

Originality/value
This paper reflects on the potential relationship between ‘urban sustainability’ and the ‘destination competitiveness’ of an urban tourism destination. This then will provide the platform for sustainability to truly contribute to future destination competitiveness.
Cultural learning process: lesson from microhistory
Authors: Yu Tianyuan , Mills Albert J. 
Published: May 2021

PurposeThe purpose of this paper is to examine the cultural learning process (namely, the development, practice and enhancement of cultural intelligence (CQ)) of a successful entrepreneur – Harold Bixby, a Pan American Airways expatriate, as reflected in the memoir of his experiences in China during 1933–1938.Design/methodology/approachThis study adopts a microhistory approach as a methodology for studying history and the past while ultimately requiring evaluations informed by the present. This paper first identifies the literature gap on CQ development and the need to study historical accounts of the past in assessing the CQ development process. This study then outlines the four key foci of microhistory as a heuristic for making sense of on-going and past accounts of selected phenomena.FindingsThis paper finds that specific personality traits (namely, openness to experience and self-efficacy), knowledge accumulation through deep cultural immersion (namely, extensive reading/study, visiting/observation and interacting/conversation), critical incident and metacognition all contributed to Bixby’s CQ development, which was a time-consuming process.Originality/valueThe study contributes to debates around cultural learning and historical organization studies by providing a rich, qualitative study of CQ assessment and CQ development through microhistory. This study highlights the importance of cognitive CQ and the function of extensive reading/studying in the process of knowledge accumulation. This paper draws attention to critical incidents as an underexplored way of learning tacit knowledge. Moreover, this study suggests metacognitive CQ can be enhanced through meditative and reflexive teaching and research practices. These findings have significant implications for cross-cultural training programs.
Epistemological considerations about mathematical concepts
Authors: Usó Doménech José Luis , Nescolarde-Selva Josué Antonio , Gash Hugh 
Published: May 2021

Purpose
Categories (particular (P) and general (V)) constitute a bipole with epistemological implications. The mutual categorical implication of this bipole is embodied in ordinary notions. It follows that a concept because it forms an element of concrete, sensible-rational, practical-theoretical activity has to unite the two inseparable poles, the general and the particular. If the concept of a physical quantity is abstract in relation to the physical object, it is concrete in comparison with mathematical quantity. This product of a secondary abstraction covers the background of physical qualities to extract the pure number, legitimately named abstract number. Both kinds of numbers are mutually exclusive: either the numbers are attached to a unit name and the number is concrete or nothing is attached and the number is abstract. However, in addition to their coordination in extension, they involve each other in comprehension: in fact, the pure number is the general pole V and concrete numbers form the particular pole of the dialectical concept of number K. The purpose of this paper is to provide a model for epistemological issues that arise in the context of meaning, concepts and use of words.

Design/methodology/approach
A dialectical theory of the binomial comprehension-extension of mathematical magnitudes.

Findings
The findings provide an objection to the traditional deductive order being also true in mathematics, and also that the reverse order cannot be considered as characteristic of mathematics, but show dialectic as universal. This opens the way to the special scientific deduction (mathematical, physical, biological, etc). going from the general to individual.

Originality/value
The structure of the mathematical concepts is elaborated.
Halochromic optical nose for assessment of spoilage of packed seer fish (II): leaching resistance, correlation between halochromism and volatile amines
Authors: Devarayan Kesavan , P. Padmavathi , Sivakami Nagaraju Kopperundevi 
Published: May 2021

PurposeDevelopment of thin film sensors with pH function for noninvasive real-time monitoring of spoilage of packed seafood such as fish, crab and shrimp are described in this study. It is also the purpose of this study to enhance the leaching resistance of the sensors by using a suitable strategy and to quantitatively correlate the sensor’s halochromism with the total volatile amine.Design/methodology/approachTo prepare halochromic sensors with better leaching resistance, biocompatible materials such as starch, agar, polyvinyl alcohol and cellulose acetate along with a halochromic dye were used to prepare the thin film sensors. These thin films were evaluated for monitoring the spoilage of packed seafood at room temperature, 4°C and −2°C up to 30 days. The halochromic sensors were characterized using UV-visible and FT-IR spectroscopy.FindingsCIELab analyses of the halochromism of the thin film sensors revealed that the color changes exhibited by the sensors in response to the spoilage of seafood are visually distinguishable. Further, the halochromic response of the thin films was directly proportional to the amount of total volatile base nitrogen that evolved from the packed seafood. Excellent leaching resistance was observed for the developed thin film sensors. The halochromic property of the sensors is reversible and thus the sensors are recyclable. Besides, the thin film sensors exhibited significant biodegradability.Originality/valueThis study provides insights for use of different biocompatible polymers for obtaining enhanced leaching resistance in halochromic sensors. Further, the color changes exhibited by the sensors are in line with the total volatile amines evolved from the packed seafood. These results highlight the importance of the developed halochromic thin film sensors for real-time monitoring of the spoilage of packed seafood.
Mapping the evolution of research themes in business ethics: a co-word network analysis
Authors: Kumar Vivek , Srivastava Arpita 
Published: May 2021

PurposeThis paper aims to map the evolution of research in business ethics from 1991 to 2018. It aims to identify the major themes and how they have evolved. It also aims to identify gaps in the literature for recommending future research agenda.Design/methodology/approachThis study uses co-word network analysis. Co-word network analysis is a bibliometric technique used to objectively identify research themes via article keywords. The study examines articles from 1991 to 2018, which is a span encompassing a greater number of articles than previous bibliometric studies in business ethics. This time span was split into four periods and major research themes were identified for each period to map the changes in research agendas in the business ethics discipline over time.FindingsThe findings point to increasing maturation of the discipline, a slight decline in ethical decision-making research, a rise in research at the intersection of leadership and ethics and exponential growth in studies on corporate social responsibility. Ethical issues in business-to-business contexts are understudied. Research in environmental disclosures and leadership is expected to grow in the future.Originality/valueThis is the first study in business ethics to use keywords for analyzing the evolution of a discipline. This study encompasses more articles than any other study in business ethics. Finally, this is the only study to use co-word network analysis to study business ethics literature.
Who to find to endorse? Evaluation of online influencers among young consumers and its implications for effective influencer marketing
Authors: Tsen Wai Sing , Cheng Benjamin Ka Lun 
Published: May 2021

Purpose
This study aims to identify the dimensions used by young consumers to evaluate effective online influencers; determine the impact of demographic segmentation – that is, gender, behavioral segmentation and whether young consumers often follow the advice of online influencers to make a purchase – on the evaluative dimensions. The results will inform advertisers regarding the types of online influencers that they should feature to endorse their products to create desirable promotion effects.

Design/methodology/approach
This study adopted a multistage method. This study first conducted eight focus groups with 48 participants between 18 and 24 years of age to explore their evaluation of online influencers. This study then conducted a survey with a questionnaire developed from the focus group results. This study used convenience sampling and administered the questionnaire to 475 participants (mean age, 19.5 years).

Findings
The results of factor analysis revealed seven dimensions used by young consumers to evaluate online influencers. The most salient dimensions were credibility, appearance and content production techniques. The results of t-testing also show that gender and behavioral segmentation variables had an impact on these evaluative dimensions in the four tested product categories.

Practical implications
This study provides advertisers with a set of criteria to select appropriate online influencers in various advertising settings, such as the promotion of gender-specific products, and in various product categories that target young consumer markets.

Originality/value
To the best of the authors’ knowledge, this is the first study to examine the dimensions used by young consumers to evaluative online influencers in relation to product endorsement.

ObjectiveEvaluate 1‐year outcomes of cervical cancer screening and treatment using primary high‐risk human papillomavirus (HPV) testing in women living with human immunodeficiency virus (HIV).DesignProspective cohort study.SettingHIV treatment centre in Botswana.PopulationWomen living with HIV.MethodsParticipants underwent cervical cancer screening with high‐risk HPV testing and triage evaluation at baseline and 1‐year follow up. Excisional treatment was offered as indicated. Histopathology was the reference standard.Main outcome measuresPersistence, clearance and incidence of high‐risk HPV infection; and persistence, progression, regression, cure and incidence of cervical dysplasia.ResultsAmong 300 women screened at baseline, 237 attended follow up (79%). High‐risk HPV positivity significantly decreased from 28% at baseline to 20% at 1 year (P = 0.02). High‐risk HPV persistence was 46% and clearance was 54%; incidence was high at 9%. Prevalence of cervical intraepithelial neoplasia Grade 2 (CIN2) or higher was most common in participants with incident high‐risk HPV (53%). CIN2 or higher was also common in those with persistent high‐risk HPV (32%) and even in those who cleared high‐risk HPV (30%). Of the high‐risk HPV‐positive participants at baseline with <CIN2, 40% progressed to CIN2 or higher at follow up.ConclusionThe high incidence of high‐risk HPV and high‐grade cervical dysplasia in women living with HIV after one round of high‐risk HPV‐based screening and treatment raises concern about the rate of progression of high‐risk HPV infection to dysplasia. Persistent disease is common. Caution in spacing cervical cancer screening intervals using high‐risk HPV testing in women living with HIV is warranted.Tweetable abstractHigh incidence and persistence of HPV and CIN2+ in women living with HIV 1 year after screening and treatment.
Medicaid healthy behavior incentives and use of dental services
Authors: Elani Hawazin W. , Kawachi Ichiro , Sommers Benjamin D. 
Published: May 2021

AbstractObjectiveTo examine changes in access to dental care in states using Section 1115 waivers to implement healthy behavior incentive (HBI) programs in their Medicaid expansion under the ACA, compared to traditional expansion states and nonexpansion states.Data sourcesBehavioral Risk Factor Surveillance System from 2008 to 2018.Study designWe used difference‐in‐differences analysis to compare changes in three Medicaid expansion states with HBI (Iowa, Indiana, Michigan) to traditional expansion (Minnesota, North Dakota, Ohio) and nonexpansion states (Nebraska, South Dakota, Wyoming) in the same mid‐Western region of the country. The sample included 32 556 low‐income adults.Data collection/extraction methodsNA.Principal findingsWe found no significant changes in dental visits associated with HBI or traditional expansion relative to nonexpansion states. HBI expansion was associated with an increase of 2.2 percentage points in reporting a dental visit in the past year for adults in urban areas (P < 0.05) while the traditional expansion was associated with a reduction of 8.5 percentage points (P < 0.01) in utilization in rural areas relative to nonexpansion states. However, after adjustment for preexisting trends, the coefficients were no longer significant, suggesting that these differences are likely due to preexisting trends.ConclusionsWe did not find evidence of increased utilization of routine dental care associated with HBI programs.

AbstractPortobello variety of Agaricus bisporus mushrooms, appreciated for its taste, makes it desirable to be eaten fresh and also as flour in soups and gravies. Gamma and electron‐beam radiation at four doses (1, 2, 5, and 10 kGy) were used to analyze its preservation effect on Portobello mushroom flour. A proximate analysis, as well as the impact on fatty acids, tocopherols, soluble sugars, organic acids, and ergosterol profiles, were performed every 3 months, during a storage period of 1 year. Gamma rays preserved mannitol (most abundant soluble sugar) over the 12 months, while electron beam radiation preserved organic acids. No significant changes were sought for any radiation type, and the slight changes extracted from the estimated marginal means reveal a tendency for irradiation as having preserving effects of nutrients and other important molecules. Thus, both irradiation types, up to 10 kGy are suitable for preservation of A. bisporus Portobello flour.
Chimeric Phi29 DNA polymerase with helix–hairpin–helix motifs shows enhanced salt tolerance and replication performance

Published: May 2021

SummaryPhi29 DNA polymerase (Phi29 Pol) has been successfully applied in DNA nanoball‐based sequencing, real‐time DNA sequencing from single polymerase molecules and nanopore sequencing employing the sequencing by synthesis (SBS) method. Among these, polymerase‐assisted nanopore sequencing technology analyses nucleotide sequences as a function of changes in electrical current. This ionic, current‐based sequencing technology requires polymerases to perform replication at high salt concentrations, for example 0.3 M KCl. Nonetheless, the salt tolerance of wild‐type Phi29 Pol is relatively low. Here, we fused helix–hairpin–helix (HhH)2 domains E‐L (eight repeats in total) of topoisomerase V (Topo V) from the hyperthermophile Methanopyrus kandleri to the Phi29 Pol COOH terminus, designated Phi29EL DNA polymerase (Phi29EL Pol). Domain fusion increased the overall enzyme replication efficiency by fourfold. Phi29EL Pol catalysed rolling circle replication in a broader range of salt concentrations than did Phi29 Pol, extending the KCl concentration range for activity up to 0.3 M. In addition, the mutation of Glu375 to Ser or Gln increased Phi29EL Pol activity in the presence of KCl. In this work, we produced a salt‐tolerant Phi29 Pol derivative by means of (HhH)2 domain insertion. The multiple advantages of this insertion make it a good substitute for Phi29 Pol, especially for use in nanopore sequencing or other circumstances that require high salt concentrations.
Genotyping single nucleotide polymorphisms and inferring ploidy by amplicon sequencing for polyploid, ploidy‐variable organisms

Published: May 2021

AbstractWhole genome duplication is hypothesized to have played a critical role in the evolution of several major taxa, including vertebrates, and while many lineages have rediploidized, some retain polyploid genomes. Additionally, variation in ploidy can occur naturally or be artificially induced within select plant and animal species. Modern genetic techniques have not been widely applied to polyploid or ploidy‐variable species, in part due to the difficulty of obtaining genotype data from polyploids. In this study, we demonstrate a strategy for developing an amplicon sequencing panel of single nucleotide polymorphisms for high‐throughput genotyping of polyploid organisms. We then develop a method to infer ploidy of individuals from amplicon sequencing data that is generalized to apply to any ploidy and does not require prior identification of heterozygous genotypes. Combining these two techniques will allow researchers to both infer ploidy and generate ploidy‐aware genotypes with the same amplicon sequencing panel. We demonstrate this approach with white sturgeon Acipenser transmontanus, a ploidy‐variable (octoploid, decaploid and dodecaploid) imperiled species under conservation management in the Pacific Northwest and obtained a panel of 325 loci. These loci were validated by examining inheritance in known‐cross families, and the ploidy inference method was validated with known ploidy samples. We provide scripts that adapt existing pipelines to genotype polyploids and an R package for application of the ploidy inference method. We expect that these techniques will empower studies of genetic variation and inheritance in polyploid organisms that vary in ploidy level, either naturally or as a result of artificial propagation practices.

AbstractObjectiveThe purpose of this study was to investigate the effects of osteoarthritis (OA) peripheral blood mononuclear cell (PBMC) ‐stimulating proteoglycan aggrecan peptides on T cells present in infrapatellar fat pads (IPFPs) and synovial tissues, and to correlate these findings with mediators present in synovial fluid of OA patients.MethodsWe tested for interleukin‐6 (IL‐6) ‐producing T cells in IPFPs of patients with knee OA using ELISPOT. Cytokine and cytotoxic mediator production from OA PBMCs, IPFPs, synovial tissues, and synovial fluids in response to proteoglycan aggrecan peptides were quantified by cytometric bead array. Patterns of cytokine and cytotoxic mediator production were analyzed and compared.ResultsT cells from IPFPs elicited strong responses towards the p263‐280 peptide by secreting IL‐6. In addition, there was a trend that the p263‐280 peptide stimulated higher production of cytokines/cytotoxic mediators than other proteoglycan aggrecan peptides, although this was not statistically significant. In patients with knee OA, a group of cytotoxic mediators (sFas, perforin, granzyme A, and granulysin) and IL‐6 were detectable at high levels from the synovial fluid. In addition, inflammation in patients with knee OA was more pronounced in joint‐surrounding tissues than levels in circulating peripheral blood.ConclusionOur data suggest that T cells responding to the p263‐280 peptide contribute to the secretion of various soluble mediators that are found within the synovial fluid. We also identified potential new candidates that may serve as biomarkers of knee OA.
