Low friction bio-inspired polydopamine/polytetrafluoroethylene coating performance in hydrodynamic bearings
Authors: Rutkevičius Marius , Dong Jimmy , Tremelling Darren , Viertel Julia , Beckford Samuel 
Published: December 2021

Purpose
Low friction polymer coatings able to withstand high loadings and many years of continuous operation are difficult to formulate at low cost, but could find many applications in industry. This study aims to analyze and compare friction and wear performance of novel polydopamine/polytetrafluoroethylene (PDA/PTFE) and traditional tin Babbitt coatings applied to an industrial journal bearing.

Design/methodology/approach
This paper tested PTFE based coating, co-deposited with PDA, a biopolymer allowing sea mussels to adhere to ocean rocks. This coating was deposited on flat steel substrates and on a curved cast iron hydrodynamic journal bearing surface. The flat substrates were analyzed with a tribometer and an optical microscope, while the coated bearing liners were tested in an industrial laboratory setting at different speeds and different radial loads.

Findings
PDA/PTFE coating showed 2-3 times lower friction compared to traditional tin Babbitt for flat substrates, but higher friction in the bearing liners. PDA/PTFE also showed considerable wear through coating delamination and abrasion in the bearing liners.

Research limitations/implications
Five future modifications to mitigate coating flaws are provided, which include modifications to coating thickness and its surface finish.

Originality/value
While the novel coating showed excellent results on flat substrates, coating performance in a large scale bearing was found to be poor. This study shows that coating preparation needs to be improved to avoid frictional losses and unwanted damage to bearings. We provide several routes that could improve coating performance in industrial applications.
Fractal model of thermal contact conductance of two spherical joint surfaces considering friction coefficient
Authors: Sun Xianguang , Meng Chunxiao , Duan Tiantang 
Published: December 2021

Purpose
The purpose of this study is to propose a fractal model of thermal contact conductance (TCC) of two spherical joint surfaces, considering friction coefficient based on the three-dimensional fractal theory.

Design/methodology/approach
The effects of friction coefficient, fractal parameters, radius of curvature and contact type on TCC were analyzed using numerical simulation.

Findings
The results indicate that the TCC decreases with the increase of friction coefficient and fractal roughness and increases with the increase of fractal dimension and radius of curvature; the contact type of two spherical joint surfaces has an important influence on the TCC, and the TCC of external contact is smaller than that of internal contact under the same contact load.

Originality/value
A fractal model of TCC of two spherical joint surfaces considering friction coefficient is proposed in this paper. Achievements of this work provide some theoretical basis for the research of TCC of bearings and other curved surfaces.
Macroeconomic impacts of fiscal shocks on the Moroccan economy: a disaggregated SVAR analysis
Authors: Alami Youssef , El Idrissi Issam , Bousselhami Ahmed , Raouf Radouane , Boujettou Hassane 
Published: December 2021

PurposeThe present paper aims to evaluate the structural impact of exogenously induced fiscal shocks on the Moroccan economy. This entails an analysis of the effect on the GDP of COVID-19-induced fiscal shocks manifesting in terms of budgetary revenues and expenditures. A key aspect of this analysis addresses the size of the tax and fiscal multipliers.Design/methodology/approachThe study examines the structural relationship between five variables during the period between Q1 2009 and Q2 2020 using an SVAR approach that allows for a dynamic interaction between ordinary expenditures and revenues on a quarterly basis.FindingsPositive structural shocks on public spending are likely to negatively impact economic growth. Negative economic growth, in turn, will damage price levels and interest rates, mainly over the long term. However, public-revenue-multiplier-associated shocks exceed these price- and interest-rate multiplier-associated shocks. Indeed, a structural shock to ordinary revenues can have a positive but insignificant impact on the GDP stemming from the ensuing decrease in the government budget deficit that proceeds from the increase in government revenues.Originality/valueThis is one of the first studies in the Moroccan context to assess the impact of the current worldwide pandemic on public finances. In addition, this study highlights the importance of boosting economic recovery through public spending.

Published: December 2021

Purpose
This study aims to illustrate an overarching picture of the knowledge base on change management, including contributing authors, institutions and countries. The study also aims to elicit the intellectual structure of the knowledge base using science mapping.

Design/methodology/approach
The authors engaged 1,457 published documents, generated from a SCOPUS search, to analyse research conducted in the area of change management. Bibliometric indicators such as authors, institutions and countries were used in the analysis. Additionally, science mapping analyses such as keyword co-occurrence and co-citation were also performed using VOSviewer.

Findings
The findings indicated that scholarly work in the field of change management is on the rise. Furthermore, while the contribution from different regions of the world was observed, the most impactful scholarly works came from the West and Asia. Finally, it was found that research on change management could be classified into four schools of thought; engineering and information and communication technology (ICT) industry, organisational aspects of change, leadership aspects of change and human aspects of change.

Originality/value
This study contributes to the knowledge base on change management by creating an intellectual landscape of the existing research. The results demonstrated that the existing literature on the topic forms four broad clusters of knowledge and that the ICT industry is the current epicentre of research in this area. These findings could benefit researchers, as well as practitioners in streamlining their actions towards the most relevant and critical areas on the topic of change management.
Impact of effective governance structure on succession process in the family business: exploring the mediating role of management succession planning
Authors: Renuka V.V. , Marath Bhasi 
Published: December 2021

PurposeThe aim of this research is to analyze empirical evidence of the effect of governance structure (GS) on perceived success of the succession process. It is also reported that in India, family firms have a more informal organization structure and governance and have an informal and unplanned approach to bringing the successors into family business. Previous studies have reported that GS is an important factor for a successful succession process. This study examines the role of management succession planning as an intervening variable to achieve perceived success of the succession process.Design/methodology/approachData have been collected using a questionnaire schedule with 113 respondents who are successors from family business firms in Kerala, India. The study uses snowball sampling technique. Partial least square-structural equation modeling has been used to do data analysis.FindingsThe results of the study showed that GS has a significant positive effect on the success of the succession process. GS has a significant positive effect on management succession planning. Management succession planning partially mediates the relationship between GS and perceived success of the succession process.Research limitations/implicationsThe results of the study indicate the effect of GS on the relationship between, perceived success of the succession process and management succession planning. The mediating role of management succession planning in the above relationship is also confirmed. Therefore, before starting the succession process a good GS should be put in place for ensuring the success of the succession process. Family firms must implement the succession plan well to make the succession process successful.Originality/valueThe main contribution of the study is to empirically investigate the effect of GS and management succession planning to enhance the success of the succession process.

Published: December 2021

PurposeThis research focuses on the implementation of Just-in-Time (JIT) inventory management, drawing on a case study of a commercial livestock farm located in a swampy area of southern Nigeria.Design/methodology/approachThe research adopts a qualitative approach. Interviews and workshops were used for data collection.FindingsFindings from the study reveal that the commitment on the internal organisational members and skilful collaboration with supply chain partners are required for effective use of JIT, especially in an odd contextual situation such as the case in this study. This also justifies the embraced of additional cost of securing JIT inventory management practices such as the situation in the case study organisation that could not allow conventional inventory management.Originality/valueIt is suggested for further research to consider the topic from a mixed method approach as well as extend the focus on the possibility of legal regulations and government support to exceptional operational practices among organisations, especially those in the context of the food production sector, where this research was based.
Measuring tourism success: how European National Tourism Organisations are shifting the paradigm
Authors: Araújo Luís 
Published: December 2021

PurposeThe paper analyses the dramatic global slowdown of tourism caused by the pandemic and how it has provided an exceptional opportunity for the tourism sector to reassess both its priorities and practices, especially in relation to our planet and society.Design/methodology/approachThis paper provides an analysis of the European Travel Commission's position regarding the development of a sustainable tourism ecosystem and the definition of new metrics to measure this transition, thus allowing European National Tourism Organisations (NTOs) to share knowledge and learn from each other.FindingsNTOs across Europe are at different stages in their journey towards a sustainable tourism development model. Some destinations are still focussing on attracting more travellers from international markets while others at a more mature stage, are switching their work towards the management of tourism flows. These latter examples support the approach that developing a tourism strategy should start with the needs of the destination, and the local people should be directly and fully involved in the tourism strategy. Initiatives such as this can support tourism decision-making based on data and firm evidence and help to address doubts and common misunderstandings around how residents feel.Originality/valueThis paper highlights how the European Travel Commission, together with its members, are working towards a new world benchmark for responsible, sustainable and innovative tourism in response to exponential growth of demand, the reality of the ecological transition and the emergence of a new digital era.
Destination management in a post-covid environment
Authors: Guerreiro Sérgio 
Published: December 2021

PurposeThis paper seeks to reflect on the impacts of the pandemic on the management of tourist destinations, discussing the role of destination-management organizations in the tourism development model, as well as the challenges that these organizations must address to ensure an effective construction of a more sustainable and competitive tourism.Design/methodology/approachThe methodology is based on a literature review linking destination management with pandemic and post-pandemic responses.FindingsThe COVID-19 pandemic represents an unprecedent shock to the tourism industry's growth model since World War II, challenging tourism stakeholders (destinations and companies) with several threats and opportunities to their future competitiveness. In addition to the massive impacts in terms of business development, the abrupt reduction of tourism demand and the significative loss of jobs, the pandemic also caused significant disruption in terms of destination-management models. In less than four months, the focus of Governments and Destination Management Organizations shifted from defining development models compatible with improving the quality of life of residents due to the emergence of the so-called overtourism phenomenon, to the urgent need to support the industry's survival, to preserve jobs and ensure conditions of safety for tourists and workers.Originality/valueDemonstrates the need for a profound change in the paradigm of destination management so that the sector is prepared to face future shocks. It also proposes further discussion on the role of destination management in the recovery process of the tourism sector in global terms, given the challenges that these organizations face. The article also considers the ways in which destination management can be a fundamental tool in the process of building a more inclusive, sustainable and competitive future.

AbstractA line blotting assay (LB) is currently used to detect myositis‐specific autoantibodies (MSAs) in patients with idiopathic inflammatory myopathies (IIMs), because of its simplicity; however, the sensitivity and specificity of this assay is low. The aim of this study is to evaluate the accuracy of the commercial LB in detection of antinuclear matrix protein 2 (NXP2) antibody. Seventy‐seven serum samples from patients with IIMs, in which anti‐NXP2 antibodies were detected through immunoprecipitation and western blotting (IP‐WB) using K562 cell lysate, were enrolled. All samples were assessed by LB and IP‐WB using recombinant human NXP2 whole protein (rNXP2) produced by insect cells, and the positive rates of each assay were compared. Thirty‐two samples (41.6%) showed false‐negativity by LB, which includes 11 samples with negative results by IP‐WB using rNXP2. Relative intensities of IP‐WB using cell lysate were significantly higher in the samples with positive results by both LB and IP‐WB using rNXP2, compared to samples with positive by IP‐WB using rNXP2 but negative by LB. Three of 11 samples with negative results by both LB and IP‐WB using rNXP2 revealed high antibody titers. Further, differences in post‐transcriptional SUMOylation were observed between recombinant and natural NXP2 proteins. In conclusion, the LB showed low sensitivity for detection of anti‐NXP2 antibody, an effect exacerbated at low titers of anti‐NXP2 antibodies. Moreover, there appears to be differences in the reactivities of antibodies to recombinant and natural NXP2 proteins with different post‐transcriptional modifications.

Published: December 2021

SummaryAnuran amphibians are susceptible to infection by intestinal nematodes, but the damage and response mechanisms that occur in their intestines after infection are only partially understood. In this study, the intestinal disruption and response mechanisms in Amolops wuyiensis frogs infected with Cosmocercoides wuyiensis n. sp. were revealed through analysis of the intestinal histopathology, digestive enzyme activity, transcriptome and intestinal microbiota. Tissue section analysis showed histological damage and inflammation in the infected intestine, and the digestive enzyme activity indicated a decrease in digestion and absorption of some nutrients. We found that infection led to differences in the intestinal microbiota composition, including lower diversity and symbiotic relationships. The greater relative abundance of the genera Burkholderia and Rhodococcus may enhance intestinal immunity to resist pathogenic infections. A comparison of the transcriptomes of infected and uninfected intestines revealed 1055 differentially expressed genes. GO enrichment and KEGG pathways analyses suggested that the guts of infected C. wuyiensis n. sp. show enhanced complement activation, cell adhesion molecule function, NOD‐like receptor signalling pathway activity and other innate immunity responses. Among the adaptive immune responses, the intestinal immune network for IgA production was significantly enriched, and the expression of IL‐17D and transforming growth factor beta‐1 genes were upregulated in the infected intestine. These results imply that C. wuyiensis n. sp. infection of A. wuyiensis intestine may trigger innate and adaptive immune responses, which reduce the post‐infection burden. Furthermore, the intestine of A. wuyiensis may also respond to C. wuyiensis n. sp. infection by increasing metallocarboxypeptidase activity and accelerating smooth muscle contraction.
The ‘Obstacle of Sex’. Christina of Sweden and Her Aspirations to the Polish–Lithuanian Throne
Authors: Gregorowicz Dorota 
Published: December 2021

ABSTRACTAn important field of research related to early modern sovereignty is the topic of female political authority. This article aims to utilise the category of gender to analyse potential obstacles that Queen Christina of Sweden had to overcome in order to obtain royal dignity in an elective monarchy, the early modern Polish–Lithuanian Commonwealth. Could the election of a female monarch constitute an acceptable and functional alternative for the Catholic and conservative noble society of this vast composite state? Former examples of Jadwiga of Anjou (1384) and Anna Jagiellon (1576) elected and crowned Kings of Poland seemed to suggest as much. The case of Christina's aspirations is all the more interesting, as her prominent supporter during the royal election of 1669 was the head of the Catholic Church, Pope Clement IX. It is, in fact, the diplomatic correspondence created by the papal Secretariat of State that constitutes the historical basis for the research presented here.
Light‐emitting diodes (below 700 nm): Improving the preservation of fresh foods during postharvest handling, storage, and transportation

Published: December 2021

AbstractIn order to maintain the original taste, flavors, and appearance, fresh foods usually do not go through complex processing prior to sale; this makes them prone to deterioration due to external factors. Light‐emitting diodes (LEDs) have many unique advantages over traditional preservation technologies leading to their increasing application in the food industry. This paper reviews the luminescence principles of LED, the advantages of LED compared with traditional lighting equipment, and its possible preservation mechanism, and then critically summarizes the beneficial effects of LED irradiation on the ripening and aging process of various fruits and vegetables (climacteric and non‐climacteric). The activity changes of many enzymes closely related to crop development and quality maintenance, and the variation of flavor components caused by LED irradiation are discussed. LED illumination with a specific spectrum also has the important effect of maintaining the original color and flavor of meat, seafood, and dairy products. For microorganisms attached to the surface of animal‐derived food, both 400–460 nm LED irradiation based on photodynamic inactivation principle and UV–LED irradiation based on ultraviolet sterilization principle have high bactericidal efficacy. Although there is still a lack of useful standards for matching optimal LED irradiation dose with wavelength, perhaps in the near future, the improved LED irradiation system will be applied extensively in the food industry.
