Published: December 2020

AbstractVoltage-gated sodium (NaV) channels initiate action potentials in excitable cells, and their function is altered by potent gating-modifier toxins. The α-toxin LqhIII from the deathstalker scorpion inhibits fast inactivation of cardiac NaV1.5 channels with IC50=11.4 nM. Here we reveal the structure of LqhIII bound to NaV1.5 at 3.3 Å resolution by cryo-EM. LqhIII anchors on top of voltage-sensing domain IV, wedged between the S1-S2 and S3-S4 linkers, which traps the gating charges of the S4 segment in a unique intermediate-activated state stabilized by four ion-pairs. This conformational change is propagated inward to weaken binding of the fast inactivation gate and favor opening the activation gate. However, these changes do not permit Na+permeation, revealing why LqhIII slows inactivation of NaV channels but does not open them. Our results provide important insights into the structural basis for gating-modifier toxin binding, voltage-sensor trapping, and fast inactivation of NaV channels.
Public value and the planet: accounting in ecological reconstitution
Authors: Vollmer Hendrik 
Published: December 2020

PurposeThis paper explores the role of accounting in ecological reconstitution and draws attention to the public value as a topic of strategic interest for developing it.Design/methodology/approachThe process of ecological reconstitution described by Latour in the “Politics of Nature” is traced towards a distinct set of accounting practices. These accounting practices, designated here as full-tax accounting, offer indications of the changing shape and role of accounting in ecological renewal.FindingsFull-tax accounting extends the planetary public towards the inclusion of nonhuman planetarians. It establishes matters of care in multimodal accounts and haunts constitutional processes with the spectre of exclusion. Starting with full-tax accounting, public-value accountants emerge as curators of matters of care.Research limitations/implicationsThe association of accounting in ecological reconstitution with matters of care highlights the mediating and immersive effects of accounting practice, inviting accounting scholars to explore these effects more systematically.Practical implicationsAccountants need to reconsider their stewardship role in relation to the fundamental uncertainties implied in planetary public-value accounting, support the process of ecological reconstitution by associating themselves with matters of care and develop ethics of exclusion.Social implicationsBroad alliances among planetary accountants are needed to extend the terms of ecological reconstitution, to gain and preserve attunement to matters of care and defend these attunements, in the atmospheric politics of ecological renewal, against regressive tendencies.Originality/valueIn problematising public value, the paper draws attention to a convergence of interests among scholars in accounting, public sector research and the environmental humanities. It presents a case for planetary accounting in ecological reconstitution that calls for participation from across disciplines, professions, arts and environmental activism.
The impact of COVID-19 on student motivation, community of inquiry and learning performance
Authors: Tan Consilz 
Published: December 2020

PurposeThis paper aims to investigate the impact of COVID-19 on the students studying in higher education institutions pre and during Movement Control Order (MCO). MCO was introduced in March 2020, and the learning process must switch from face-to-face to online learning in schools and universities. This study particularly focuses on university students by analyzing the students' motivation, the community of inquiry and learning performance. In total, three factors are examined in the construct of the community of inquiry, namely social presence, cognitive presence and teaching presence.Design/methodology/approachThis paper provides quantitative analysis and paired sample t-tests on the students' learning motivation, the community of inquiry and learning performance. This paper presents the analysis of the online learning preference of 282 university students and examines whether there is significant difference in preference before and during MCO.FindingsThe findings indicated that the students lost motivation and learning performance using online learning methods during the MCO period. There is a lack of infrastructure to support the learning and social support from the lecturers and peers.Research limitations/implicationsThis research helps to explore improvements that are needed to manage such a pandemic to support teaching staff and students.Practical implicationsThe COVID-19 is a pandemic that has affected the learning process of the students, and it should not be neglected even when it is over. Policymakers shall consider providing more training and better infrastructures to cater to smooth Internet connection and platform for online learning. Students are not able to focus on learning using online learning methods and, they lack motivation during the pandemic. The teaching faculty also need to be well-trained in delivering online courses and to be more tech-savvy.Social implicationsWith the detailed analysis of the students' learning motivation, the community of inquiry and learning performance, it helps to promote a better education environment.Originality/valueThis is the first study to examine the learning motivation and performance model as well as the community of inquiry during the pandemic. It is evident that university students initially have a high level of motivation and community of inquiry before the pandemic but yield a significant drop during the MCO. The paper presented how COVID-19 seriously impacted on the learning experience.
Influence of CEOs’ religious affiliations on firms’ advertising spending and shareholder value
Authors: Oh Hannah , Bae John , Currim Imran S. , Lim Jooseop , Zhang Yu 
Published: December 2020

Purpose
This study aims to answer two unique related questions on the overarching relationship between a CEO’s personal religious affiliation, the firm’s advertising spending decision and its shareholder value. First, does the CEO’s religious affiliation, a proxy for risk taking, influence the firm’s advertising spending decision? Second, does the advertising spending decision mediate the relationship between the CEO’s religious affiliation and the firm’s shareholder value?

Design/methodology/approach
This study uses data on the religious affiliations of CEOs of publicly listed US firms, 1992–2014, from Marquis Who’s Who; advertising spending and shareholder value from Compustat, and panel data-based regression models including CEO characteristics from ExecuComp, and firm-, industry- and time-based controls.

Findings
We find higher advertising spending levels for Protestant over Catholic-led firms, and advertising spending mediates the relationship between a CEO’s religious affiliation and the firm’s shareholder value.

Research limitations/implications
Marketing theory needs to incorporate the missing but fundamental effect of the CEO’s religious affiliation-based values on decisions and outcomes.

Practical implications
Boards of Directors may need to align the CEO’s and their firm’s spending goals.

Originality/value
While previous studies focused on the influence of religious affiliation on consumers’ attitudes and behavior, and executives’ financial and R&D spending decisions, this study, to the best of the authors’ knowledge, is the first to investigate the effect of a CEO’s religious affiliation on the firm’s advertising spending decision and its shareholder value.
Diabetes self-management: what role does the family play?
Authors: Ligita Titan , Harvey Nichole , Wicking Kristin , Francis Karen , Nurjannah Intansari 
Published: December 2020

PurposeThis paper aims to explicate one of the major findings of a research study seeking to understand how Indonesian people with diabetes learn about their disease. The one key finding discussed in this paper is how families influence the learning and self-management processes adopted by Indonesian people with diabetes.Design/methodology/approachA grounded theory methodology was adopted to investigate how Indonesian people with diabetes learn about their disease. Twenty-eight semi-structured interviews were undertaken with Indonesian people living with diabetes, families of people living with diabetes, healthcare professionals and other healthcare providers. Data was analysed by using constant comparative analysis during three coding stages.FindingsThe study explicated the basic social process of how people with diabetes in Indonesia learn about their disease through a generated theory “Learning, choosing, and acting: self-management of diabetes in Indonesia”. This study found family engagement was integral to Indonesian people living with diabetes who were self-managing their disease. Families assisted with seeking information, providing recommendations, selecting and implementing actions, appraising implemented actions, and informing others about their experiences. By acknowledging that family is involved in this process, the healthcare professional can adequately provide health education to both the person with diabetes and their families. Involving families in health education is crucial as family can influence decision making made by people with diabetes in a proper or improper way. Thus, clinicians need to also skilfully recognise difficulties these people encounter by monitoring their self-management progress and by working closely with them and their family members.Originality/valueThis is the first study conducted in Indonesia that specifically investigates the process of how people with diabetes learn about their disease. The involvement of families in this process is a central finding of the study. Families can enhance the overall health and well-being of the person with diabetes, aid in early recognition of aberration to health status and trigger the initiation of interventions to re-establish homeostasis if they are actively engaged and supported by health professionals.

Published: December 2020

Purpose
The purpose of this paper is to know the influence of heat generation/absorption and slip effects on heat and mass transfer flow of carbon nanotubes – water-based nanofluid over a rotating disk. Two types of carbon nanotubes, single and multi-walled, are considered in this analysis.

Design/methodology/approach
The non-dimensional system of governing equations is constructed using compatible transformations. These equations together with boundary conditions are solved numerically by using the most prominent Finite element method. The influence of various pertinent parameters such as magnetic parameter (0.4 – 1.0), nanoparticle volume fraction parameter (0.1 – 0.6), porosity parameter (0.3 – 0.6), radiation parameter (0.1 – 0.4), Prandtl number (2.2 – 11.2), space-dependent (−3.0 – 3.0), temperature-dependent (−3.0 – 1.5), velocity slip parameter (0.1 – 1.0), thermal slip parameter (0.1 – 0.4) and chemical reaction parameter (0.3 – 0.6) on nanofluids velocity, temperature and concentration distributions, as well as rates of velocity, temperature and concentration is calculated and the results are plotted through graphs and tables. Also, a comparative analysis is carried out to verify the validation of the present numerical code and found good agreement.

Findings
The results indicate that the temperature of the fluid elevates with rising values of nanoparticle volume fraction parameter. Furthermore, the rates of heat transfer rise from 4.8% to 14.6% when carbon nanotubes of 0.05 volume fraction are suspended into the base fluid.

Originality/value
The work carried out in this analysis is original and no part is copied from other sources.

Authors: Schröder Katharina , Tiberius Victor , Bouncken Ricarda B. , Kraus Sascha 
Published: December 2020

PurposeStrategic entrepreneurship (SE) depicts the nexus of strategic management and entrepreneurship, suggesting that firms can create superior wealth when simultaneously pursuing advantage-seeking and opportunity-seeking behavior. As the rapid growth in SE research led to a multidisciplinary, scattered and fragmented literature landscape, the authors aim to structure this research field.Design/methodology/approachThe authors employ a bibliographic coupling and literature review of the strategic entrepreneurship research field.FindingsThe authors identify and describe five major research streams with 15 sub-themes in recent SE research. Based on our findings, the authors propose an integrated research framework and research gaps for future research.Originality/valueTo the authors’ knowledge, this is the first review on SE based on a bibliographic coupling.
Training and development climate and administrative employees' productivity in higher education
Authors: Balwant Paul Tristen , Mohammed Rebecca , Singh Riann 
Published: December 2020

PurposeThe purpose of the present study is to investigate mediating mechanisms in the relationship between the training and development climate at higher education institutions and administrative employees' productivity. Organizational identification theory and the job demands-resources model are used to investigate supervisor support, employees' motivation to learn and employee engagement as mediators.Design/methodology/approachSurvey research was used to collect data from 289 administrative staff members employed at five higher education institutions in Trinidad and Tobago.FindingsThe findings supported the hypothesized mediating role of supervisor support, employees' motivation to learn and employee engagement in the relationship between organizations' training and development climate and employee productivity.Social implicationsProductivity is a major problem in Trinidad and Tobago. In Trinidad and Tobago's higher education sector, productivity deficiencies are particularly problematic because of the gradual reduction in government subsidies. Therefore, higher education institutions must improve productivity, particularly administrative employees' productivity, in order to compete with local and international tertiary education institutions. This study contributes to Trinidad and Tobago's society by showing the importance of both a positive training and development climate and supervisor support to influence administrative employees' affective states and productivity in tertiary education institutions.Originality/valueThis study adds to existing research on training and development and employee productivity by introducing novel and theoretically sound mediators to clarify how the relationship between a higher education institution's training and development climate and its administrative employees' productivity unfolds.
Influence of category attitudes on the relationship between SERVQUAL and satisfaction in Islamic banks; the role of disruptive societal-level events
Authors: Farrag Dalia Abdel Rahman , Murphy William H. , Hassan Mohammed 
Published: December 2020

Purpose
The purpose of this study is to modify the service quality scale (SERVQUAL) for measuring the performance of Islamic banks after modifying and validating it to fit the Islamic banking context. Furthermore, it provides insights for the limitations good service delivery has on maintaining favorable provider’s satisfaction in Islamic banks under conditions when category attitudes have been disrupted and made salient by major disruptive events.

Design/methodology/approach
Focus groups (managers of Islamic banks) were conducted to develop context-specific service quality measures. Exploratory factor analysis and CFA have been conducted to test the validity of scales developed and questionnaires were then sent to Islamic banking customers of major Islamic banks in Egypt for testing the relationships between the research variables and hypotheses developed.

Findings
The findings of this study are two-fold; identifying a service quality dimension not previously identified in extant service quality measures (SERVQUAL, CARTER), devotion to customers and alerts brand managers that harm to category attitudes caused by societal-level disruptive events can make it difficult to gain high satisfaction even with superior customer service. In this disruptive event context, although high service quality is associated with brand satisfaction, brand satisfaction seems unexpectedly dampened by category attitudes, perhaps, due to the general malaise felt toward the category following the disruptive events.

Practical implications
Islamic institutions are alerted to the heightened need for providing superior service, as even superior service may no longer assure high satisfaction. Extrapolating to an even bigger societal disruptor, in the soon-to-come post-COVID-19 world, category attitudes toward walk-in banking services will be in turmoil and highly salient. So, brand managers will need to develop creative ways to strengthen not just brand attitudes but also to re-stabilize category attitudes if the category is to recover.

Originality/value
This is considered a pioneer study in using mixed methods to re-think the famous SERVQUAL scale in a unique context and relating findings to impacts of disruptive events on attitude toward Islamic banking.
Brand bravery: conceptualization, scale development and validation
Authors: Jain Kokil , Jajodia Isha , Sharma Piyush , Singh Gurinder 
Published: December 2020

Purpose
Brands today operate in a dynamic business environment, which often requires them to take courageous actions, from taking a stand on controversial issues to responding to changing market needs. However, these actions are not merely strategic but also represent a unique aspect of the brands’ identity, which includes holding up to their core values and being resilient to social pressure. To better understand this positive virtue, the current study introduces the concept of brand bravery – a novel brand archetype that emulates the brand’s distinct identity. This study aims to conceptualize brand bravery and develop a psychometrically sound scale to measure it and investigate its relationship with positive brand relationship outcomes.

Design/methodology/approach
Two qualitative studies were conducted to identify the dimensions of perceived brand bravery. Three empirical studies develop and validate the proposed measurement scale and confirm the construct’s nomological validity by proposing a framework that explains the outcomes of perceived brand bravery.

Findings
Results from multiple studies support a seven-factor second-order reflective scale of perceived brand bravery, with dimensions altruism, bold, courageous, determined, enduring, fearless and gritty. The construct of brand bravery is found discriminant from other conceptually distinct but related brand attributes. Nomological validity tests further suggest that perceived brand bravery leads to positive consumer-related outcomes such as brand advocacy behaviors, positive attitude and consumer brand identification.

Practical implications
Brand bravery provides a vital roadmap to marketers who have sought to create a leading brand that can stay relevant in times of disruption. The multi-factor scale can help managers track, which dimension of the brand bravery scale is more relevant for shaping overall bravery perception.

Originality/value
The study introduces a novel brand attribute that has not been previously discussed beyond social and moral psychology literature. It conceptualizes brand bravery that will strengthen the understanding of this specific brand characteristic and provides a practical scale to measure brand bravery.
Information asymmetry and REITs’ excess dividends: US and European market comparison
Authors: Morri Giacomo , Palmieri Federico , Sironi Emiliano 
Published: December 2020

PurposeThe purpose of this study is to analyze the determinants that lead REITs to pay out more dividends than the required level to retain their tax-favored status. In particular, the focus is on the effect that information asymmetry has on REITs’ excess dividends distribution.Design/methodology/approachA sample of 341 REITs from the USA, France, the UK, Spain, Belgium, Germany, the Netherlands and Italy has been analyzed for the period 2000–2016. Employing multiple linear regression models, the effects of information asymmetry, cash flow, size, ROA, leverage and treasury shares on excess dividends have been explored.FindingsResults indicate that REITs with greater information asymmetry distribute significantly more excess dividends, with superior evidence in Europe than in the USA. Regarding other determinants, cash flow influences excess dividends the most, whereas ROA and common shares repurchase have an inverse relationship with excess dividends.Practical implicationsThe paper explores the effects of excess dividends distribution on the most relevant REITs features. The joint analysis of the European and the US samples allows this study to make a comparison between the two markets and to identify affinities and differences.Originality/valueThe paper tests whether a proxy of asymmetry information plays a role in affecting the excess dividends distribution. In contrast to previous researches, it expands the analysis by comparing the US and European markets to underline any difference in the effect of asymmetry information on excess dividends. The topic has never been investigated before in relation to the European market.

Authors: Yu Chunxia , Leng Yi , Li Jing , Yu Jiacheng 
Published: December 2020

Purpose
This paper aims to propose a novel blockchain crowdfunding projects evaluation approach using extended techniques for order preferences by similarity to ideal solution (TOPSIS) under fuzzy environment.

Design/methodology/approach
By analyzing the characteristics and operation process of blockchain crowdfunding model, this paper formulates the evaluation index system from three dimensions of human resources, capital and publicity. In addition, the entropy method is used to calculate the weight of each indicator to avoid subjective judgments; different alternatives are evaluated using the grey correlation analysis (GRA) and TOPSIS-integrated method which considers the distance and similarity between alternatives simultaneously.
