Published: November 2020

AbstractIn cultivated tetraploid potato, reduction to diploidy (dihaploidy) allows hybridization to diploid germplasm, introgression breeding, and may facilitate the production of inbreds. Pollination with haploid inducers yields maternal dihaploids, as well as triploid and tetraploid hybrids. It is not known if dihaploids result from parthenogenesis, entailing development of embryos from unfertilized eggs, or genome elimination, entailing missegregation and loss of paternal chromosomes. A sign of genome elimination is the occasional persistence of haploid inducer DNA in some of the dihaploids. We characterized the genomes of 1,001 putative dihaploids and 134 hybrids produced by pollinating tetraploid clones with three haploid inducers, IVP35, IVP101, and PL4. We detected inheritance of full or partial chromosomes from the haploid inducer parent in 0.87% of the overall dihaploid progeny, irrespective of the combination of parental genotypes. Chromosomal breaks commonly affected the paternal genome in the dihaploid and tetraploid progeny, but not in the triploid progeny. Residual haploid inducer DNA is consistent with genome elimination as the mechanism of haploid induction. Further, the fact that paternal chromosome breaks are specific to dihaploids and tetraploid progeny suggests that they may be specific to 2x sperms, and supports the hypothesis that 2x sperms facilitate genome elimination.
Direct detection of coupled proton and electron transfers in human manganese superoxide dismutase

Published: November 2020

AbstractHuman manganese superoxide dismutase (MnSOD) is a critical oxidoreductase found in the mitochondrial matrix. Concerted proton and electron transfers (CPETs) are used by the enzyme to rid the mitochondria of O2•−, a precursor to other harmful reactive oxygen and nitrogen species. The mechanisms of CPET-utilizing enzymes are typically unknown due to the difficulties in detecting the protonation states of specific residues and solvent molecules involved in catalysis while controlling the redox state of the enzyme. Here, neutron diffraction of redox-controlled MnSOD crystals revealed the all-atom structures of Mn3+SOD and Mn2+SOD delivering unique data on sites that change protonation state. A novel mechanism is proposed from the direct observation of glutamine deprotonation, the involvement of Tyr and His with altered pKas, and four unusual strong-short hydrogen bonds, including a low barrier hydrogen bond, that change with the oxidation state of the metal. Quantum calculations provide insight into the electronic modulation of the observed structures and the enzymatic mechanism.
An academic digital library advancing an equitable and inclusive educational environment
Authors: La Macchia Karen 
Published: November 2020

Purpose
At an academic digital library of a graduate business school in Berlin, Germany, the librarian reflects on the “new normal” following the onset of the COVID-19 pandemic, with its increased faculty and student engagement with digital resources and heightened awareness of and activity in diversity, equity and inclusion (DEI) initiatives.

Design/methodology/approach
This paper details the concepts and practices of an academic library that is a center for information resources and services, as well as a contact point for DEI advocacy and student conflict mediation. The librarian is the only information professional at the school, and this is a reflective essay written from her perspective.

Findings
This case study suggests that a librarian cross-trained as a conflict mediator or coach can offer both information literacy and support services to further the development of an inclusive campus environment. Educators in both roles build students’ competence and confidence, focus on their achievements and progress and contribute to their sense of belonging. Combining these activities in a central institution builds on the strengths of both disciplines and is consistent with inclusion as a core principle of librarianship.

Originality/value
The findings will be useful for librarians wishing to expand their existing mandate to provide inclusive information access and services to include DEI initiatives.
The representation of homosexuals in Arabic-language news outlets
Authors: Al-Abbas Linda S. , Haider Ahmad S. 
Published: November 2020

PurposeThe purpose of this study is to examine the most frequent countries and prevalent discourses in the context of homosexuality in the headlines of Arabic-language media outlets.Design/methodology/approachThis study combined both corpus linguistic (CL) quantitative and critical discourse analysis (CDA) qualitative approaches to analyse five thousand two hundred news headlines that were retrieved from the Factiva news database from 2010 to 2019.FindingsThere were six main categories of subjects covered by the media in the context of homosexuality, namely crime, extremist groups, legislation, authority figures and scandals, culture and countries. The analysis showed that the countries whose laws criminalize homosexuals were more frequent than those seen to be supportive of homosexuals. The findings revealed that homosexuals are under-covered in the Arab media, and whenever they are present in the news reports, they are depicted negatively.Research limitations/implicationsThis study examined the representation of homosexuals in Arabic headlines from 2010 to 2019. Future researchers may investigate their construction in the body of the articles in different periods and languages.Practical implicationsThe present research has implications regarding the necessity of objectivity in covering news about minority groups without being influenced by the stock of ideas circulating in the culture where media outlets report.Social implicationsThe social implications include enhancing the principles and values of solidarity and respecting all groups in society.Originality/valueAlthough there is considerable literature on the representation of homosexuals in media outlets, the number of articles that investigated the same concept in the Arab region is relatively limited to the best knowledge of the researchers. Therefore, this study can add great significance to existing knowledge as it tackles a limitedly investigated topic in the Arab world.
Geographical aggregation and incubator graduation performance: the role of incubator assistance
Authors: Hou Bojun , Hong Jin , Yang Yang 
Published: November 2020

PurposeThis paper attempts to use agglomeration theory and ecological theory to explore how geographic agglomeration affects the graduation performance of incubator community. The authors argue that increasing the incubator community density can improve the opportunities for mutualism and learning among incubators. However, as the competition intensifies, the above positive relationship will weaken when the incubator density exceeds a certain level.Design/methodology/approachThe authors use a unique panel dataset of 438 National Technology Business Incubators (NTBIs) in China spanning from 2008 to 2012. Since each NTBIs contains multiple observations for different years, these observations that belong to a cross-section are not completely independent of each other; therefore, the regression using ordinary least squares method underestimates the standard deviations of the variables. To solve this problem, the authors regress this cluster panel data using the Newey–West robust variance estimator.FindingsThe empirical results show that incubator community density is conducive to promoting incubation performance, while the positive relationship between the incubator community density and incubation performance gradually weakens as the population density of incubators surpasses a certain level. Further, the authors examine how incubator assistance (technical assistance and business assistance) moderates the relationship between incubator density and incubation performance. The results indicate that this positive relationship is stronger when more business assistance is provided by incubator managers, while the moderating role of technical assistance is not supported.Originality/valueThis paper enriches the research on the relationship between incubator community density and graduation performance from the perspective of incubator assistance which helps start-ups to understand, absorb and transform external knowledge and resources, thereby promoting their growth.
Campaign participation, spreading electronic word of mouth, purchase: how to optimise corporate social responsibility, CSR, effectiveness via social media?
Authors: Bialkova Svetlana , Te Paske Stephanie 
Published: November 2020

PurposeThe purpose of this paper is to investigate how to optimise corporate social responsibility (CSR) when communicating via social media. In particular, the communication type, cause proximity and CSR motives are addressed facing the increased demand for transparency and the grown consumers' expectations towards socially responsible brands.Design/methodology/approachOnline survey was developed, based on a profound literature review and a field research we did on the actual social media behaviour of socially responsible brands. Consumers attitudes and behavioural reactions in terms of willingness to participate in a campaign, to spread e-WOM and to purchase were investigated, as a function of CSR motives (value vs performance vs value and performance) and cause proximity (national vs international), respectively, with monologue (study 1) and dialogue communication type (study 2).FindingsCause proximity enhanced the campaign participation, and this effect was pronounced for both, monologue and dialogue type of communication. CSR motives modulated the willingness to spread electronic word-of-mouth, and this holds for both, monologue and dialogue communication. Attitudes and purchase intention were highest when value- and performance-driven motives were communicated, but these effects appeared only when the message was in a dialogue form of communication. Message credibility and CSR motives credibility perception further modulated consumers response.Practical implicationsThe outcomes could be used in developing marketing (communication) strategies leading to values and revenues optimisation.Originality/valueThe results are discussed in a framework of how CSR resonates via social media.
A qualitative study of soft skills development opportunities: perceptions of university information professionals
Authors: Ahmad Sajjad , Ahmad Shehzad , Ameen Kanwal 
Published: November 2020

Purpose
The purpose of this paper is to study the self-perceptions of university information professionals about continuous professional development (CPD) opportunities regarding their soft skills.

Design/methodology/approach
A qualitative design using in-depth interviews was used. The population was all the information professionals working in the public sector universities of Pakistan, but the geographic range of the population, to reduce travelling expenses and to complete the study in time, the interviews were restricted to the universities of the capital city Islamabad and provincial capital Peshawar. A total of 21 interviews were conducted using a snowball sampling technique to select information professionals.

Findings
The findings revealed that only three information professionals attended CPD opportunities in soft skills. More than half of the information professionals stated that CPD programmes have an overall “good” impact on the development of their soft skills. Similarly, more than half of the participants stated that CPD training opportunities on soft skills are very limited. The majority of the participants held professional associations responsible for the development of information professionals’ soft skills. It was also found that communication and persuasion skills, self-management skills and interpersonal skills were the top three soft skill categories for which they urged CPD programmes.

Research limitations/implications
During interviews, most of the Assistant Librarians were not expressive and comfortable. This might be because of a lack of their soft skills knowledge, poor communication skills and interview anxiety.

Originality/value
According to the authors’ knowledge, this study is the first of its kind in Pakistan that dealt with the CPD opportunities regarding soft skills of university information professionals using a qualitative research design.
Intrinsic irreversibility of Al2O3–H2O nanofluid Poiseuille flow with variable viscosity and convective cooling
Authors: Almeida Felicita , Gireesha B.J. , Venkatesh P. , Ramesh G.K. 
Published: November 2020

Purpose
This study aims to investigate the flow behavior of aluminum oxide–water nanofluid with variable viscosity flowing through the microchannel parallel with the ground, with low aspect ratio. The study focuses on the first and second law analyses of Poiseuille flow using water as the base fluid with alumina nanoparticles suspended in it. Combined effects of thermal radiation, viscous dissipation, variable viscosity, nanoparticle shape factor and volume fraction on the thermal performance are studied and the in-built irreversibility in the process is examined.

Design/methodology/approach
The governing equations with dimensions are reduced to non-dimensional equations by using dimensionless quantities. Then, the Runge–Kutta–Fehlberg shooting scheme tackles the present non-linear equations.

Findings
The outcomes of the present analysis reveal that the activation energy parameter with its increase, depletes the exergetic effectiveness of the system, thus defending the fact to keep the activation energy parameter the lowest as possible for the system efficiency. In addition, thermal radiation and Biot number enhance the release of heat energy, thereby cooling the system. Bejan number graph exhibits the decreasing behavior for the increased nanoparticle shape factor, whereas the temperature enhances with the rise in nanoparticle shape factor.

Originality/value
The effects of nanoparticle shape factor in Poiseuille flow for alumina–water nanoliquid in low aspect ratio microchannel is inspected at the earliest. Exergetic effectiveness of the system is studied and heat transfer characteristics are explored for thermal radiation effect and activation energy parameter. Besides,

Authors: Hu Shi 
Published: November 2020

Purpose
By drawing on leader–member exchange theory, this study aims to understand the relationship between job autonomy, transformational leadership and psychological well-being mediated by job satisfaction among front-line employees in Chinese commercial banks.

Design/methodology/approach
A cross-sectional study which consists of 96 respondents from 5 Chinese commercial banks is conducted.

Findings
Through data analysis, the results reveal that transformational leadership and job autonomy are significantly positively related to job satisfaction and directly related to the psychological well-being of front-line employees in Chinese commercial banks. Another interesting finding is that there is a mean difference between male and female front-line employees in Chinese commercial banks on the preference of job autonomy and transformational leadership.

Originality/value
The current study offers further evidence for which strategies Chinese commercial banks should adopt to enhance and protect the rights of front-line employees’ psychological well-being. As front-line employees in commercial banks play a vital role in contributing to bank profits and operational efficiency. They are not only the employees for making profits but also have the right to experience the psychological well-being as a human. Employees with a high level of job satisfaction and psychological well-being benefit both their own health and organizational performance in the long run.
Developing a fair currency system
Authors: Hanif Muhammad 
Published: November 2020

PurposeThis study aims to evaluate the role of the prevailing currency systems in achieving (or departing from) the socio-economic objectives of a progressive and just society; i.e. featuring stability and equitable distribution of wealth.Design/methodology/approachAfter documenting historical developments in currency systems, the study reviews the Islamic perspective on the matter. Features of an ideal currency system are listed and then a critical evaluation of existing currency systems – fiat, banking and cryptocurrency – is undertaken.FindingsIt is found that existing currency systems – fiat, banking and cryptocurrency – are not compatible with the socio-economic objectives of a forward-looking, progressive society, which upholds transparency and justice as its core values. The study documents that Sharīʿah norms have no preference or dislike for any of the existing currency systems. Any prudent currency system compatible with the objectives of the Islamic financial system (i.e. stability and equitable distribution of wealth) is acceptable. A single international reserve currency (with country-specific legal tendering) is subject to the risk of destabilisation across global markets.Practical implicationsThis paper recommends autonomy of central banking, the spending of seigniorage for the welfare of community members, development of asset-backed currencies (followingṣukūkstructures), as well as multiple international reserve currencies and joining of hands by professionals and Sharīʿah scholars to design a currency system compatible with the Islamic financial system. This paper’s recommendation is against the adoption of cryptocurrency that lacks the backing of real assets.Originality/valueThe study contributes to the literature by evaluating the compatibility of existing currency systems in the achievement of socio-economic objectives of a welfare state which seeks to uphold justice and equitable resource distribution as core values in the financial system.
Population growth and human resource utilization nexus in Nigeria
Authors: Adeosun Oluyemi Theophilus , Popogbe Oluwaseyi Omowunmi 
Published: November 2020

PurposePopulation growth has remained a key issue facing developing economies in the world. While developed countries are experiencing diminished or negative population growth, many countries in sub-Saharan Africa including Nigeria are having population growth above the economic growth rate. With the deadline for the sustainable development goals approaching, attention is increasingly being focused on population growth and human capital development. Extant literature focused on population growth, human resource utilization and economic growth but this study aims to examine the effect of population growth on human resource utilization.Design/methodology/approachUsing secondary data for the period 1990-2018, the study conducted unit root test and co-integration analyses to determine the stationarity and correlation in the long-run in the variables. The study used the error correction model to ascertain the speed at which shocks can be corrected in the long-run. Granger causality test was also carried out to ascertain the direction of causality among the variables.FindingsThe empirical results revealed that population growth has a negative and significant effect on human resource utilization. The study also revealed that unidirectional causality runs from employment rate to population growth rate and a unidirectional causality runs from employment growth rate to expected years of schooling. The Nigerian Government needs to not only control population growth but also focus on the quality of education.Originality/valueThe paper provides insights into the relationship between population growth and human capital utilization in Nigeria focusing on the 1986-2018 period.

Determinants of recovery satisfaction and service loyalty: the differing effects of service recovery system and service recovery performance
Authors: Kamath Pallavi R. , Pai Yogesh P. , Prabhu Nandan K.P. 
Published: November 2020

PurposeThis study aims to explore whether frontline employees' service recovery performance as well as customers' recovery satisfaction (RS) act as mediating mechanisms that simultaneously transmit the positive influence of an integrated service recovery system (SRS) on customers' service loyalty (SL).Design/methodology/approachA total of 134 useable retail banking branch cases (including responses from 134 branch heads, 439 frontline employees and 941 customers) were used to test our model using the partial least squares structural equation modeling (PLS-SEM) approach.FindingsService recovery system, measured as a higher-order multidimensional construct, has a strong and positive influence on customers' SL. Besides, service recovery performance partially mediates, along with RS, the relationship between SRS and SL. Finally, customers' recovery satisfaction has the strongest influence on service loyalty.Practical implicationsThis study strongly suggests that practitioners not only focus on implementing an effective SRS but also on leveraging service recovery performance and RS to build sustained customers' loyalty. Practitioners must provide more attention to training their frontline employees, reward and recognize employees and continually evaluate their employees' recovery efforts.Originality/valueThe role of frontline employees' service recovery performance and customers' RS as mediating mechanisms in transmitting the positive effect of SRS on customers' SL is investigated using the combined perspectives of social-technical system theory and interdependence theory.
