Molecular conflicts disrupting centromere assembly contribute to Xenopus hybrid inviability
Authors: Kitaoka Maiko , Smith Owen K. , Straight Aaron F. , Heald Rebecca 
Published: March 2022

ABSTRACTAlthough central to evolution, the causes of hybrid inviability that drive reproductive isolation are poorly understood. Embryonic lethality occurs when eggs of the frog X. tropicalis are fertilized with either X. laevis or X. borealis sperm. We observed that distinct subsets of paternal chromosomes failed to assemble functional centromeres, causing their mis-segregation during embryonic cell divisions. Core centromere DNA sequence analysis revealed little conservation among the three species, indicating that epigenetic mechanisms that normally operate to maintain centromere integrity are disrupted on specific paternal chromosomes in hybrids. In vitro reactions combining X. tropicalis egg extract with either X. laevis or X. borealis sperm chromosomes revealed that paternally matched or over-expressed centromeric histone CENP-A and its chaperone HJURP could rescue centromere assembly on affected chromosomes in interphase nuclei. However, whereas the X. laevis chromosomes maintained centromeric CENP-A in metaphase, X. borealis chromosomes did not, and also displayed ultra-thin regions containing ribosomal DNA. Both centromere assembly and morphology of X. borealis mitotic chromosomes could be rescued by inhibiting RNA Polymerase I or by preventing collapse of stalled DNA replication forks. These results indicate that specific paternal centromeres are inactivated in hybrids due to disruption of associated chromatin regions that interfere with CENP-A incorporation, at least in some cases due to conflicts between replication and transcription machineries. Thus, our findings highlight the dynamic nature of centromere maintenance and its susceptibility to disruption in vertebrate interspecies hybrids.ONE SENTENCE SUMMARYCentromere incompatibilities in inviable Xenopus hybrids are sequence-independent and result from disruption of epigenetic pathways required for centromere maintenance.
Intragenomic rearrangements in SARS-CoV-2, other betacoronaviruses, and alphacoronaviruses
Authors: Patarca Roberto , Haseltine William A. 
Published: March 2022

AbstractVariation of the betacoronavirus SARS-CoV-2 has been the bane of COVID-19 control. Documented variation includes point mutations, deletions, insertions, and recombination among closely or distantly related coronaviruses. Here, we describe yet another aspect of genome variation by beta- and alphacoronaviruses. Specifically, we report numerous genomic insertions of 5’-untranslated region sequences into coding regions of SARS-CoV-2, other betacoronaviruses, and alphacoronaviruses. To our knowledge this is the first systematic description of such insertions. In many cases, these insertions change viral protein sequences and further foster genomic flexibility and viral adaptability through insertion of transcription regulatory sequences in novel positions within the genome. Among human Embecorivus betacoronaviruses, for instance, from 65% to all of the surveyed sequences in publicly available databases contain 5’-UTR-derived inserted sequences. In limited instances, there is mounting evidence that these insertions alter the fundamental biological properties of mutant viruses. Intragenomic rearrangements add to our appreciation of how variants of SARS-CoV-2 and other beta- and alphacoronaviruses may arise.SignificanceUnderstanding mechanisms of variation in coronaviruses is vital to control of their associated diseases. Beyond point mutations, insertions, deletions and recombination, we here describe for the first time intragenomic rearrangements and their relevance to changes in transmissibility, immune escape and/or virulence documented during the SARS-CoV-2 pandemic.
Exploring factors affecting mobile-banking app adoption: a perspective from adaptive structuration theory
Authors: Ali Ahsan , Hameed Abdul , Moin Muhammad Farrukh , Khan Naseer Abbas 
Published: March 2022

PurposeThe study has two aims: first, it aimed to investigate the impact of contextual factors (such as information quality, service quality, system quality, trust in applications (app) and COVID-19 health anxiety) on the intention to use the Mobile Payment (MP) app, and subsequently, the actual use of the app. Second, the aim of this study is whether the COVID-19 threat has a moderating influence on the relationship between customers' intent to use MP app and the actual use of MP app.Design/methodology/approachThe data are collected through an online survey from 341 Mobile Banking (MB) app users from Pakistan to empirically analyze the relationship between service quality, system quality, information quality, trust in the app, COVID-19 health anxiety and COVID-19 threat, intentions to use MB-app and actual use of MB-app.FindingsThe empirical analysis of the data collected from MB-app users from Pakistan shows that service quality, system quality, information quality, trust in the app and COVID-19 health anxiety positively related to intentions to use MB-app, consequently affect the actual use of MB-app. Furthermore, the results demonstrate that the COVID-19 threat positively moderates the relationship between intentions to use MB-app and actual use of MB-app.Originality/valueAlthough, prior research established a positive impact of mobile apps on customer service and consumer satisfaction. Yet, it is not clear which factors influence customers to adopt MB-app. This study contributes to the research on MB-apps based on adaptive structuration theory and examines the technological factors and contextual factors that collectively explain when and how individuals decide to adopt MB-app.
Encouraging pro-environmental consumption behaviour amongst Gen-Y consumers: right messages to different consumers?
Authors: Nguyen Hung Vu , Do Long Thanh , Le Mai Thi Thu 
Published: March 2022

PurposeMedia information is often considered critical to foster pro-environmental consumption behaviours (PECB). However, empirical evidence was inconsistent about the impact of environmental information exposure on the behaviours. Thus, the study aims to clarify that impact by investigating three different types of environmental information. Moreover, the study posited that consumers who hold different environment-related values may be receptive to and influenced differently by these types of information.Design/methodology/approachSurvey data were collected from 259 Gen-Y consumers in urban areas. The data were analysed for measure reliabilities and validities before hypotheses were tested using ordinary least squares (OLS) regressions.FindingsThe results revealed that the environmental problem-, action- and effectiveness-related information exposure affects pro-environmental personal norms (PNs) which then influence the behaviours. More importantly, the influences of action-related information and effectiveness-related information on PNs were moderated differently by egoistic values held by consumers.Originality/valueThe study contributes to the literature by highlighting the importance of information-value congruence in designing effective media campaigns.
Examining the influence of customer-brand relationship constructs and bandwagon effect on brand loyalty
Authors: Anantharaman Rajesh , Prashar Sanjeev , Tata Sai Vijay 
Published: March 2022

PurposeOrganizations are being compelled to revamp their loyalty programs due to the increase in digital transactions, customer acquisition costs and competition in the loyalty market. Given the significance of consumer-brand relationships, businesses must quickly identify the relationships that best elicit brand loyalty. Thus, this study seeks to develop a comprehensive model about the consumer-brand relationship that encompasses the following constructs: brand trust, brand satisfaction, brand preference, brand affect, brand equity, brand image, commitment, variety seeking, and relationship length, and their influence on brand loyalty. The study also investigates the impact of the bandwagon effect, in tandem with the aforesaid antecedents.Design/methodology/approachA data set comprising 248 consumers in India was used to validate the measures and test the hypotheses. Structural equation modeling was employed to test the hypothesis. The data analysis was carried out on R version 4.0.2.FindingsThe study found that all the selected constructs exert influence on brand loyalty, although commitment, brand equity and brand preference exhibited the strongest impact. The bandwagon effect also demonstrated a strong effect.Originality/valueThis study advances the field's understanding of information processing through a consolidated meta-view of various consumer-brand relationship constructs along with bandwagon effects. Perhaps the most important contribution is shedding light on the influence of bandwagon effects on brand loyalty.
Decision support system for tower crane location and material supply point in construction sites using an integer linear programming model
Authors: Amiri Roya , Majrouhi Sardroud Javad , Momenaei Kermani Vahid 
Published: March 2022

PurposeThe site layout has a significant impact on the efficiency of construction operations. Planning an effective site layout partly involves identifying and positioning temporary facilities such as tower cranes and areas on the jobsite for materials storage. This study proposes an approach to optimizing the type and location of the tower crane and material supply point on construction sites.Design/methodology/approachThe problem is formulated into an integer linear programming (ILP) model considering the total cost of material transportation as the objective function and site conditions as constraints. The efficacy of the approach is demonstrated by finding the optimum site layout for a numerical example. The proposed model is validated and verified using two methods.FindingsResults indicate that the proposed model successfully identifies the type and location of the tower crane and the location of material supply point, leading to approximately 20% cost reduction compared with when such features of a site layout are decided solely based on experience and educated guesses of the construction manager.Originality/valueThe primary contribution of this study is to present a modified linear mathematical model for site layout optimization that exhibits improved performance compared with previous models. The type and location of the tower crane and the material supply point as decision variables are extracted directly from solving the proposed model. The proposed model will help enhance time and cost efficiency on construction sites.
Corona fear and e-commerce adoption in an emerging economy: paradigm shift of consumer intention
Authors: Raza Syed Ali , Khan Komal Akram 
Published: March 2022

Purpose
The lockdown in the spring of 2020 significantly disrupted businesses. Unquestionably, countless dealers who had to shut their shops for weeks were hit hardest by the crisis. Similarly, consumers also face many difficulties, especially in emerging economies. At this time, e-commerce is the only available option that people can use to fulfill their needs. In developing states, people prefer to buy things from shops. Hence, it raises a concern about whether people will adopt e-commerce in the COVID-19 pandemic. The study aims to examine the consumers’ intention to adopt e-commerce by incorporating corona fear as a moderator.

Design/methodology/approach
The statistical techniques applied to the data set were confirmatory factor analysis and partial least square structural equation modeling.

Findings
The findings depict that perceived usefulness, perceived ease of use, subjective norms, perceived lack of alternatives are positively and significantly connected with the intention to adopt e-commerce. However, perceived risk, perceived behavioral control and attitude have a positive but insignificant effect. Additionally, moderating analysis results depict that corona fear moderates the associations between perceived risk, perceived usefulness, subjective norms and attitude. However, no moderating effect is found in perceived ease of use and perceived behavioral control.

Originality/value
The present research is the initial attempt that analyzes consumers’ intention to accept e-commerce during the corona pandemic in a country like Pakistan, where the trend of physical shopping is more favorable among consumers. Also, it includes the moderating role of corona fear to understand how this fear has shaped the consumers’ intention to shop online? Additionally, the technology acceptance model framework is expanded by including perceived risk and perceived lack of alternatives in the research model.

Economic policy uncertainty and other determinants of corporate cash holdings of Australian energy companies
Authors: Trinh Nga Thu , Nguyen Thanh Pham Thien , Nghiem Son Hong 
Published: March 2022

Purpose
This study aims to investigate a new determinant of corporate cash holdings of Australian energy firms: economic policy uncertainty (EPU). Based on two motives for holding cash: precautionary and speculative motives, the authors argue that EPU increases financing constraints or induces firms to postpone investment projects, thereby increasing their cash holdings. The authors examine whether the Australian policy-related economic uncertainty affects cash holdings of Australian energy companies.

Design/methodology/approach
This research uses a data set of Australian energy firms from 2010 to 2020 and the Australian EPU index, which measures the uncertainty in economic policy, using news coverage of eight major Australian newspapers. To address the potential endogeneity bias and ensure the robustness of the results, three models are used: ordinary least squares, fixed-effects and dynamic generalized method of moments.

Findings
The authors find that the EPU index has a significant and positive effect on cash holdings, after controlling for firm-specific factors. While firm size and dividend payments have mixed and insignificant effects, other determinants are significant, such as growth opportunities, net working capital, cash flow, cash flow risk, leverage and capital expenditure. The authors also find that the positive effect of EPU on cash holdings is not the manifestation of EPU affecting corporate investments but rather explained by financing constraints.

Practical implications
The findings have implications for policymakers and regulators in Australia as the uncertainty of their economic policies plays an important role when Australian energy companies determine their cash holding level to manage liquidity risks.

Originality/value
This study is the first to document EPU index as the new determinant of corporate cash holdings of Australian energy companies. Firms in this sector have a great need of funding and liquidity for their operations and capital-intensive projects. High EPU index induces them to hold more cash to avoid liquidity shocks.
The market for energy advice in Germany: a progress review
Authors: Ringel Marc , Mjekic Saranda , Knodt Michèle 
Published: March 2022

Purpose
This study aims to update a 2017 review of trends, barriers and outlooks for the future of the energy advice services market in Germany, as perceived by market actors. With growing national and European ambitions for comprehensive energy renovations, lessons for a functioning energy sector management can be drawn that are valid at European and international level.

Design/methodology/approach
This review combines quantitative and qualitative research approaches, using a survey covering over 500 energy advisors and follow-up qualitative stakeholder interviews. Based on the present market, this study seeks to identify feedback on regulatory measures to promote market development; remaining barriers against further market development; and business and cooperation models for energy services in the building sector.

Findings
Since the last review in 2017/2018, market development has tended to stagnate, despite a strong government commitment to boost energy services markets. Significant barriers persist, many of which are related to government regulation. These barriers discourage homeowners to engage in energy renovations. To support innovative business models, regulatory complexity needs to be reduced. European Union lawmakers and German Government need to take action to facilitate access to advice services.

Originality/value
This paper provides the latest, updated sectoral overview of Europe’s biggest energy service market as perceived by the market actors. It focuses on the analysis of barriers, business models and cooperation models to derive governance options for further triggering market dynamics.
The impact of corporate governance on forward-looking CSR disclosure
Authors: Ananzeh Husam , Alshurafat Hashem , Bugshan Abdullah , Hussainey Khaled 
Published: March 2022

Purpose
This paper aims to examine the impact of corporate governance mechanisms on forward-looking corporate social responsibility (CSR) disclosure (FCSRD).

Design/methodology/approach
The authors use the manual content analysis to measure FCSRD for a sample of 94 companies listed on the Amman Stock Exchange from 2010 to 2016. Data on companies' FCSRD are manually collected from annual reports. The authors also use regression analyses to test the research hypotheses.

Findings
The authors find that board size positively affects FCSRD, while CEO duality and family ownership negatively impact FCSRD.

Originality/value
To the best of the authors’ knowledge, this is the first evidence of how governance mechanisms affect FCSR information in corporate annual reports in a developing country.
Challenges resulting from hawala banking for anti-money laundering and anti-terrorist financing policies of Swiss banks
Authors: Teichmann Fabian Maximilian Johannes , Wittmann Chiara 
Published: March 2022

Purpose
The purpose of this paper is to illustrate threefold how hawala banking poses a problem for Swiss banks implementing anti-money laundering (AML) and anti-terrorist financing (ATF) policies as a fulfilment of Switzerland’s UN commitment.

Design/methodology/approach
The first author interviewed compliance officers and suspected criminals on hawala banking mechanisms. The authors formally recorded interviews with compliance officers, but interviews with suspected criminals were not recorded to maximize their potential forthrightness. In total, the authors conducted 70 formal interviews and developed a questionnaire based on this, which was sent to 200 compliance officers. The authors subjected the interviews to qualitative analysis and developed a system of categories that the authors assessed by means of triangulation. By substantiating proposed theoretical challenges with empirical findings, future recommendations for regulatory procedures are based on analytical evidence.

Findings
This study finds that hawala presents significant challenges for AML and ATF policies. Whilst it is possible to mediate the first two challenges laid out herein, it is the third hurdle that proves insurmountable. Ultimately, tolerating hawala banking passively counteracts any active effort made by implementing AML and ATF policies.

Originality/value
Whilst the existing literature sufficiently connects hawala banking to terrorist financing, this study details how existing compliance measures are circumvented and the implications on the perceived commitment of Switzerland against financial crime.
Third-party and creditor rights: provisional attachment under §5 of the Indian PMLA, 2002
Authors: Sethi Sarthak , Davis Kevin 
Published: March 2022

Purpose
The purpose of this paper is to consider the effect of the Prevention of Money Laundering Act (PMLA), 2002 on the property rights of third parties, by evaluating whether the interpretation of the scheme of the PMLA, 2002 results in a deprivation of rights, by virtue of the provision for the provisional attachment of property.[AQ3] In doing so, this paper attempts to consider two sub-categories of third parties that stand affected by §5 of the PMLA, 2002.

Design/methodology/approach
Primarily the authors analyse diverging judgements and case law across various high courts to evaluate the position of law with regards to attachment of property. To reach a precise legal conclusion, the authors consider the composite scheme of the PMLA, 2002 in their analysis.

Findings
It has been concluded that there is a clear lack of judicial cohesion in the interpretation of the PMLA, 2002, and in the absence of a judgement by the Supreme Court of India, enforcement authorities have failed to correctly identify the boundaries of the offence of money laundering, resulting in a dangerous deprivation of rights.

Originality/value
This paper fills a vacuum of detailed scholarship on anti-money laundering provisions in India, while also being contemporaneously relevant, as it considers the effects of the PMLA, 2002 on bona fide economic transactions and secured creditors.
