Published: February 2020

A new organic–inorganic hybrid salt [L]2[MnCl4] (I) where L
+ is the 2-methyl-3-(pyridin-2-yl)imidazo[1,5-a]pyridinium cation, is built of discrete organic cations and tetrachloridomanganate(II) anions. The L
+ cation was formed in situ in the oxidative cyclocondensation of 2-pyridinecarbaldehyde and CH3NH2·HCl in methanol. The structure was refined as a two-component twin using PLATON (Spek, 2020) to de-twin the data. The twin law (−1 0 0 0 − 1 0 0.5 0 1) was applied in the refinement where the twin component fraction refined to 0.155 (1). The compound crystallizes in the space group P21/c with two crystallographically non-equivalent cations in the asymmetric unit, which possess similar structural conformations. The fused pyridinium and imidazolium rings of the cations are virtually coplanar [dihedral angles are 0.89 (18) and 0.78 (17)°]; the pendant pyridyl rings are twisted by 36.83 (14) and 36.14 (13)° with respect to the planes of the remaining atoms of the cations. The tetrahedral MnCl4
2– anion is slightly distorted with the Mn—Cl distances falling in the range 2.3469 (10)–2.3941 (9) Å. The distortion value of 0.044 relative to the ideal tetrahedron was obtained by continuous shape measurement (CShM) analysis. In the crystal, the cations and anions form separate stacks propagating along the a-axis direction. The organic cations display weak π–π stacking. The anions, which are stacked identically one above the other, demonstrate loose packing; the minimum Mn...Mn separation in the cation stack is approximately 7.49 Å. The investigation of the fluorescent properties of a powdered sample of (I) showed no emission. X-band EPR data for (I) at 293 and 77 K revealed broad fine structure signals, indicating moderate zero-field splitting.
Corporate governance and stock liquidity: evidence from a speculative market
Authors: Biswas Pallab Kumar 
Published: February 2020

Purpose
Grounded in lemon market theory, this paper aims to examine the influence of corporate governance (CG) on stock market liquidity in Bangladesh, where stock market manipulation because of speculative trading is a common concern.

Design/methodology/approach
This study is based on a sample of 2,420 firm-year observations covering all non-financial firms in Bangladesh from 1996 to 2011.

Findings
This study’s results show a significant relationship between governance and liquidity within firms over time. In particular, within firms, when governance quality increases, liquidity significantly improves. For instance, a rise in the governance quality by one standard deviation decreases the illiquidity ratio by 55.97%. The results are unlikely to be confounded by endogeneity.

Practical implications
The results have important policy implications for security regulators, investors, traders and managers. The results support the current regulatory trend of strengthening CG practices in the listed firms in Bangladesh.

Originality/value
This study contributes to the understanding of the role of effective firm-level CG on stock liquidity in the context of an emerging country. Consistent with prior research mostly conducted in the advanced economies, it provides further empirical support that higher CG quality reduces the information asymmetry problem and enhances stock liquidity even in a speculative market.
Facing failure
Authors: Beatson Nicola , Berg David , Smith Jeffrey K. 
Published: February 2020

Purpose
The purpose of this study is to investigate failure in an introductory accounting course. Failure rates are often hard to explain and have a cost to both the individual and to the university. This paper offers insight into this complex matter.

Design/methodology/approach
This paper uses data gathered from a survey instrument on self-efficacy beliefs and personal written reflections from students who had previously failed the introductory accounting course to diagnose why students may have failed.

Findings
The key finding in this paper is that students are individuals and there can be multiple reasons for failure.

Research limitations/implications
One limitation in this paper is the sample size of six-student reflections. This in itself speaks to the difficultly in researching this area, as students are often not willing to face failure and discuss it.

Practical implications
The main contribution from this paper is an awareness for educators, as failure can occur for multiple reasons. This paper both adds to the literature on failure in accounting courses and helps inform educators of why their students may fail.

Originality/value
It is very challenging to research failure and therefore there is very little work on this area. At this time, the authors have no knowledge of any papers, which address the failure rates in introductory accounting courses from the individual perspective. Therefore, this paper has a unique contribution to the field of accounting education.
Voluntary assurance of sustainability reporting: evidence from an emerging economy
Authors: Hassan Abeer , Elamer Ahmed A. , Fletcher Mary , Sobhan Nawreen 
Published: February 2020

PurposeThis paper aims to investigate the supply and demand side of sustainability assurance in Bangladesh.Design/methodology/approachDrawing on signalling theory, a logistic regression model is used for a sample of 100 of the largest Bangladeshi companies to study the relationships between assurance, sustainability disclosure, industry membership and reporting format.FindingsAuthors’ results show that companies which produce more sustainability information are more likely to get their sustainability assured, to be from non-carbon intensive industries, and are more likely to integrate their sustainability information with the financial annual reports. Authors’ results support the argument that organisations based in weaker legal environments are more likely to secure assurance as this adds to the credibility and reliability of sustainability reports.Research limitations/implicationsThis paper has limitations which raise some issues for future research. First, the authors have covered only large companies; therefore, future research could examine the differences between small and large companies in relation to assurance. Secondly, the authors’ data consist of company sustainability disclosure information in the fiscal year 2015. Longitudinal studies are recommended to extend this research. Finally, future research could examine the moderating effects of geographical location on the relationship between assurance (and its providers) and other variables.Practical implicationsThe findings of this paper will prove valuable to practitioners and researchers. Practitioners, including assurance providers and sustainability reporting managers will benefit from authors’ study as it covers both the demand and supply side characteristics of assurance. Researchers will benefit from the study as it investigates assurance practices in the developing country of Bangladesh.Originality/valueTo the best of the authors’ knowledge, this is the first study to examine both the supply and demand sides of sustainability assurance in Bangladesh. Authors also introduce reporting format when measuring the relationship between assurance and its determinant factors at micro level. The study also links assurance to signalling theory.

Authors: Unuigbe Maria , Zulu Sambo Lyson , Johnston David 
Published: February 2020

PurposeThe purpose of this paper is to explore the perceptions and experiences of building practitioners in the adoption of renewable energy (RE) in commercial buildings in Nigeria.Design/methodology/approachA qualitative methodology was used guided by the principles of the Grounded Theory Method (GTM). Data were collected using in-depth semi-structured interviews with a purposive sample of five industry practitioners.FindingsFive distinct factors emerged, namely, being compliant, change in mindset, normalising, being autonomous and identity. The research revealed the significance of contextual (cultural) peculiarities and the role identity plays in informing RE adoption. The findings substantiate the significance of RE adoption in the future practice of building practitioners and in ensuring environmental stability within the Sub-Saharan Africa (SSA) context.Research limitations/implicationsThe study focuses on commercial office buildings and attempts to provide contextual grounding to inform theory generation as part of a wider study.Originality/valueThis research contributes methodologically and empirically by providing grounded insight into the adoption of RE in commercial buildings. Thereby, enabling a much greater understanding of the issues associated with enhanced promotion and adoption by professionals and stakeholders, which can inform policy interventions. Furthermore, it will benefit further research within the SSA context and provide valuable lessons associated with adopting GTM in construction research.
Extending the experience construct: an examination of online grocery shopping
Authors: Singh Reema , Söderlund Magnus 
Published: February 2020

Purpose
This study aims to assess factors influencing customers’ online grocery shopping experiences, and it evaluates the central role of customer service and consumers’ responses to satisfying grocery shopping.

Design/methodology/approach
A mixed-methods approach was used; linguistic inquiry and the word count (LIWC) method captured qualitative aspects of consumers’ grocery shopping experience, whereas partial least square-structure equation modeling tested hypotheses regarding antecedents to consumers’ overall online grocery shopping experience.

Findings
The PLS-based analysis confirmed the qualitative insights, establishing the significance of customer service, which accounted for 68% variance in the overall experience and 42% variance in customer satisfaction, along with other experience antecedents such as website, product and delivery.

Research limitations/implications
Future researchers could further analyze experience as a dynamic process focusing on consumer and retailer brand-focused constructs, specifically focusing on creating a holistic understanding of customer service that establishes coherence between retailers’ marketing values and their customer service.

Practical implications
Managers should acknowledge the importance of customer service in creating a satisfying customer experience, and they should respond to consumer concerns, resulting in enhanced brand-related experience.

Originality/value
Responding to the call for a better understanding of customer service, this study brings out the challenges online grocery shoppers are facing in terms of customer service and empirically establishes customer service as a key driver of customer experience, thereby extending the earlier work on customer service and online customer experience.
A classification model for prediction of clinical severity level using qSOFA medical score
Authors: Olivia Diana , Nayak Ashalatha , Balachandra Mamatha , John Jaison 
Published: February 2020

Purpose
The purpose of this study is to develop an efficient prediction model using vital signs and standard medical score systems, which predicts the clinical severity level of the patient in advance based on the quick sequential organ failure assessment (qSOFA) medical score method.

Design/methodology/approach
To predict the clinical severity level of the patient in advance, the authors have formulated a training dataset that is constructed based on the qSOFA medical score method. Further, along with the multiple vital signs, different standard medical scores and their correlation features are used to build and improve the accuracy of the prediction model. It is made sure that the constructed training set is suitable for the severity level prediction because the formulated dataset has different clusters each corresponding to different severity levels according to qSOFA score.

Findings
From the experimental result, it is found that the inclusion of the standard medical scores and their correlation along with multiple vital signs improves the accuracy of the clinical severity level prediction model. In addition, the authors showed that the training dataset formulated from the temporal data (which includes vital signs and medical scores) based on the qSOFA medical scoring system has the clusters which correspond to each severity level in qSOFA score. Finally, it is found that RAndom k-labELsets multi-label classification performs better prediction of severity level compared to neural network-based multi-label classification.

Originality/value
This paper helps in identifying patient' clinical status.

Published: February 2020

PurposeThis research aims to develop an index for measuring Indonesian quality label awareness among motorcycle helmet users. The index measures quality label awareness and its antecedent variables, which are the variables that represent marketing effort on promoting the quality label.Design/methodology/approachThe indicators of the index were derived from a literature review. A survey was performed. The respondents are 487 motorcycle drivers and passengers helmet users in Jakarta. The authors conducted some statistical analyses, namely, exploratory factor analysis, Cronbach’sαanalysis, and multiple regression analysis.FindingsA quality label awareness index was developed and tested. The index consists of quality label awareness and its determinants. The determinants are label marketing clarity and label marketing credibility. The research result showed that the index is valid and reliable.Research limitations/implicationsThe authors performed the survey only at Jakarta using convenience sampling technique. Thus, the findings may not be generalized to other contexts. Given this, replication research is important to be performed in the future in order to test the stability of the findings in other contexts.Practical implicationsThe index can be used to evaluate the effectiveness of quality label and quality label marketing programs.Originality/valueThis study is believed to be the first to develop and test consumers' quality label awareness index.
Determinants of capital structure; a sector-level analysis for Indian manufacturing firms
Authors: Panda Ajaya Kumar , Nanda Swagatika 
Published: February 2020

PurposeThe purpose of this paper is to empirically analyze the determinants of capital structure and their long-run equilibrium relationships with firm-specific and macroeconomic indicators for Indian manufacturing firms.Design/methodology/approachThe study is conducted using the panel semi-parametric and non-parametric regression models to identify the key determinants of capital structure. Panel cointegration models are also employed for analyzing the long-run equilibrium association of capital structure with its determinants.FindingsThe study finds that each manufacturing sector has unique determinants of capital structure. The debt level is significantly affected by asset tangibility, growth opportunity, effective tax rate, non-debt tax shield, cash flow, profitability, firm size, foreign investment, government borrowing, economic growth, and interest rate. All these firm-specific and macroeconomic variables have strong long-run equilibrium relationship with capital structure as a whole.Practical Implication of the StudyThe study analyzes the determinants of capital structure for eight manufacturing sectors of India, which helps firm managers and policy-makers to identify appropriate factors that maximize firm value. The sector-specific features of firms may lead to a new path with regard to corporate governance and ownership structure to enhance stakeholder's satisfaction.Originality/valueThe use of semi-parametric and non-parametric panel regression models to analyze the determinants of capital structure, and the use of panel cointegration approach to explore the long-run equilibrium relationship between the determinants and its factors are the unique contributions of the present research.
The impact of climate change on firm adaptation: the case of the wine industry
Authors: Galbreath Jeremy , Tisch Daniel , Quaddus Mohammed , Rabbanee Fazlul 
Published: February 2020

Purpose
The purpose of this study was to test the effects of climate change, as manifested in both temperature and rainfall changes, on adaptive practices in a sample of wine firms operating in South Australia. Given that firms’ adaptation to the external environment can be advanced through effective internal learning systems, a further purpose was to explore the moderating effect of absorptive capacity.

Design/methodology/approach
The authors used a survey as well as secondary sources to collect data. Regression analysis was used to test the hypotheses. To test the robustness of the results, alternative measures of temperature and rainfall changes were used.

Findings
By studying 207 wine firms, the analysis suggests that climate change is significantly and positively associated with adaptive practices. Further, as hypothesized, absorptive capacity positively moderates both relationships.

Research limitations/implications
The use of a single industry in a specific location limits the generalizability of the results. Implications suggest that when the effects of climate change are considered the natural environment might be accorded salient stakeholder status. Further, when absorptive capacity is high, firms appear to adapt to climate change at a greater rate, suggesting that internal learning systems are important.

Originality/value
This is one the few studies in the business literature that considers the effects of actual physical changes in the natural environment on firm behaviour. Further, the paper is one of the few to incorporate natural stakeholder-based theory as a means of exploring climate change. The research paves the way for future studies of responses to such changes.
Energetic coefficient of friction applied to cylinder liners lab tests
Authors: do Vale Joao Luiz , da Silva Carlos Henrique , Pintaude Giuseppe 
Published: February 2020

Purpose
This paper aims to present a proposal for evaluating the coefficient of friction (COF), under a reciprocating test that considers the energy dissipated by the friction force. In addition, this new parameter is compared to average COF, which is often used to evaluate COF in reciprocating tests.

Design/methodology/approach
Samples of compacted graphite iron were extracted directly from an internal combustion engine block. The piston ring used was a nitrided martensitic stainless steel with an asymmetrical profile, and the lubricant oil was the SAE 30 CF, controlled at 40°C. Different testing conditions were carried out in a CETR-UMT-Bruker tribometer, varying loads between 25-125 N, frequencies between 1-12.5 Hz and track length between 3-10 mm. Three maps comparing the average COF and the energetic definition were built, allowing to discuss their similarities.

Findings
In general, both parameters had similarities especially for low frequencies and small tracks. However, for test conditions that imposed higher accelerations (i.e. longer track lengths and higher frequencies), the energetic COF (COFe) was lower than the average COF (COFa) and presented better agreement in Stribeck-like curves – independent on the experienced lubrication regime along the stroke. As the COFe can be interpreted as a weighted average of instantaneous COF in relation to in-track displacements, an immediate consequence is that instantaneous COF closest to mid-stroke is considered more significant. Furthermore, perturbations associated with the intrinsic accelerations of the movement test are minimized in the COFe formulation.

Originality/value
The energetic COF parameter (COFe) is presented and compared to the average COF. The new parameter presented less data dispersion and is attractive to evaluate the COF behavior in reciprocating tests, as its formulation minimizes perturbations associated with the intrinsic accelerations of the movement (mainly in the initial and final part of the track where the acceleration has its greatest magnitude).

The potential of using wild edible animals as alternative food sources among food-insecure areas in Indonesia
Authors: Adi Annis Catur , Andrias Dini Ririn , Rachmah Qonita 
Published: February 2020

PurposeThis study aims to assess the household food security status and explore the potency of wild edible animals as a food source in the food insecurity–prone area of Bangkalan district, Madura, Indonesia.Approach/methodology/designThis cross-sectional quantitative study used a mixed-method approach. A total of 66 participants were purposively recruited. Household food security was assessed using the short version of the U.S. Household Food Security Survey Module (US-HFSSM). A list of available wild edible animals was obtained from each interview using a structured questionnaire. For the qualitative study, an in-depth interview was conducted among key informants at subvillage level.FindingsWe found that 33.4 percent of households were food insecure. At least 18 kinds of wild edible animal protein consumed by the respondents were identified in the study area, which consisted of five kinds of insects, five kinds of fish, three types of birds, and two mammals. Most of the wild edible animals were rich in protein.Originality/valueWild edible animals can be promoted to support household food security. Villagers did not usually consider consuming wild edible animals as a normal practice as there were concerns about the taste and safety of eating wild animal foods. Methods of processing and cooking foods to improve the taste and safety aspects need to be explored. The information obtained from this study adds more evidence related to the potential of edible wild animals as a food alternative for households in food-insecure areas.

Published: February 2020

Purpose
This paper aims to attempt to investigate and test the factors related to social media advertisement that could forecast the intention to subscribe to Islamic banking products in Malaysia.

Design/methodology/approach
The research framework used in this study is guided by the Unified Theory of Acceptance and Use of Technology (UTAUT). The questionnaire method was used to collect data from 360 social media users and partial least square (PLS) analysis was carried out for the model’s validation.

Findings
The analytical results showed that perceived relevance, informativeness and perceived expectancy were found to have a statistical relationship with the purchase intention of Islamic banking products via a social media platform.

Practical implications
The study offers a practical implication in which the findings prove as helpful means for Islamic financial institutions to discover paramount techniques to retain existing customers and at the same time encourage potential new customers to subscribe to their products.

Originality/value
Deficiency of research focusing on social media marketing, especially the incorporation of the UTAUT model was observed in the literature. Thus, this paper offers additional literature on social media marketing and elucidates their role in Islamic banking industry, particularly from the Malaysian context. This research is considered to be among the primary attempts to examine the drivers of social media marketing and customers’ intention to subscribe to Islamic banking products in Malaysia.
