Abstract

Purpose

The purpose and current research objective is to determine sustainable hotel performance through hotel environmental management initiatives (HEMI) with the mediating influence of employee’s’ eco-friendly behaviour (EEB), and to determine the moderating role of environmental strategies (ES) in the relationship between HEMI and EEB.

Design/methodology/approach

A total of 95 five-star hotels were contacted, with data collected from only 30 of them. The study used only 433 questionnaires for the final analysis with SPSS 25.0 and SmartPLS 3.2.8.

Findings

The results revealed that HEMI is positively associated with sustainable hotel performance and with EEB. EEB is positively associated with sustainable hotel performance. ES significantly influence EEB, and significantly strengthen the relationship between HMEI and EEB. EEB significantly mediates the relationship between HEMI and sustainable hotel performance.

Practical implications

The current research highlights a significant issue: how the management of the hotel industry uses HEMI, ES and EEB to improve sustainable performance. The study fills the gap in the literature and enables hotel management to concentrate on studying exogenous variables to increase sustainable performance.

Originality/value

The current research contributes to the body of knowledge by concentrating on factors that influence sustainable hotel performance. It examines HEMI influence on sustainable performance with moderating (ES) and mediating (EEB) effects, from the leans of natural resource-based view (RBV) theory.

Abstract

Purpose

The purpose of this paper is to examine the impact of corporate social responsibility (CSR) on customer relationship quality (RQ) based on three main aspects of RQ, namely, satisfaction, trust and commitment.

Design/methodology/approach

A quantitative meta-analysis of 80 unique effect sizes reported in 60 articles (n = 27,805) was conducted to determine effect sizes of the relationship between CSR and the aspects of RQ of the customer. Furthermore, the economic development has been examined as potential moderators between CSR and RQ.

Findings

Meta-analysis suggests that a positive relationship between CSR and the three studied aspects of RQ is well established; however, the strength of studied relationships has revealed variations in magnitude. Customer commitment was affected by CSR (r = 56) the most, closely followed by customer trust (r = 0.52), while customer satisfaction (r = 0.44) was affected the least. Moreover, the result of meta-regression shows that the economic development moderates only one relationship, CSR and trust.

Originality/value

Presenting a summary of the direction of primary research on the relationship between CSR and RQ, as no prior meta-analysis on the primary relationship has been conducted till date (to the best of the authors’ knowledge).

Abstract

Purpose

The impact of the coronavirus disease 2019 (COVID-19) pandemic on architectural education (AE) was investigated, and a framework was proposed to reduce the impacts' negative consequences.

Design/methodology/approach

Systematic literature review, bibliometric and content analyses were combined to gain an in-depth understanding of the effects of the pandemic on AE and projections for its future. Relevant documents were extracted from the Web of Science (WoS) database. Bibliometric connections in the context of AE and COVID-19 pandemic were explored using text-mining and content analysis was performed.

Findings

The challenges, development tendencies and collaboration networks in AE during the pandemic were quantitatively and qualitatively analyzed. The most influential articles, journals, authors and countries/regions were highlighted using a bibliometric analysis. The analysis of keyword tendencies and clusters indicates that new concepts have emerged in AE research during the pandemic involving online, in-person and hybrid education. Using content analysis of 57 subtopics, 39 (18) were categorized as having negative (positive) effects. A comprehensive mitigation framework was designed to reduce the impact of the pandemic on AE.

Research limitations/implications

The study findings can enable practitioners to construct effective solutions to COVID-19- and other disaster-related problems regarding AE. The implications, obstacles and mitigation framework presented can help identify gaps in the literature and guide further research.

Originality/value

This paper presents the first bibliometric and content analysis of AE and COVID-19 pandemic-related studies published from January 2020 to June 2022 to highlight several research directions and academic development within the field.

Abstract

Purpose

This study aims to explore the perceptions of accountancy students on the use of technology, blended learning and flipped classroom in two emerging UK higher education institutions (HEIs).

Design/methodology/approach

The primary data for the study were collected using a questionnaire survey and descriptively analysed.

Findings

The findings revealed that there is some use of technology in terms of the Blackboard and PowerPoint presentations but blogs and wikis have very limited use. An aspect that does not seem to be integrated fully yet is the use of blended technology and a flipped classroom.

Practical implications

The study findings offer a picture of how technology, blended learning and the flipped classroom technique were utilised with accountancy students prior to the coronavirus disease 2019 (COVID-19) pandemic. This information is valuable for accounting educators and by extension to other aspects of business studies disciplines in providing a comparison between the pre-COVID-19 scenario and the current one and thus enabling an evaluation of advancement in the application of these teaching strategies as a result of the pressure imposed by social distancing. Such intelligence will facilitate the identification of areas where enhancing learning outcomes has been possible and point to opportunities for improved student experience.

Originality/value

Where COVID-19 brought about significant structural change in teaching and learning in the HE environment, this study represents a pre-COVID-19 consideration of student perceptions on blended learning and flipped classroom. This study thus has the potential to anchor future relevant studies that consider the post-COVID-19 environment.

Abstract

Purpose

Probiotic fermented foods are fast being recognized as health foods. Most of such foods are based on dairy products but little research work is available on coarse cereals and millets, which constitute the staple foods in developing countries. This paper aims to determine the effect of germination and fementation on nutrient composition of pearl millet based food blends.

Design/methodology/approach

Indigenously developed pearl millet based food blends containing raw and germinated pearl millet flour, whey powder and tomato pulp (2:1:1w/w) were autoclaved, cooled and fermented with 5 percent Lactobacillus acidophilus curd which supplied 106cells/ml to the slurry at 37°C for 12 h. The unfermented blends, after autoclaving, served as controls. The developed food blends were subjected to nutritional evaluation by using the standard methods of analysis. The data were statistically analysed.

Findings

Pearl millet based, germinated, autoclaved and fermented, food blend maintained adequate cell viability (8.64 cfu g‐1) as compared to non‐germinated food blend. Germination and probiotic fermentation caused significant improvement in the contents of thiamine, niacin, total lysine, protein fractions, sugars, soluble dietary fibre and in vitro availability of Ca, Fe and Zn of food blends.

Practical implications

Research is currently aimed at developing probiotic millet based food mixture, which had enhanced nutrient profile. Hence, it can be considered for commercialization after establishing its health/therapeutic implications among the population.

Originality/value

Dairy foods have preferentially been used as the carrier medium for probiotics. This paper explores the possibility of using staple foods as the carrier medium. The consumption of such food mixtures containing viable probiotic bacteria should be enhanced among consumers in term of their role in health maintenance and disease prevention.

Abstract

Purpose

Traditionally prepared enset-based products like bulla are characterised by low protein and vitamin contents and are highly viscous; this causes protein-energy malnutrition especially in infants and young children. This paper aims to improve the nutritional and sensory qualities of enset-based food with pumpkin and amaranth.

Design/methodology/approach

Sixteen formulations of composite flour were generated using a D-optimal constrained mixture design with a range of 50-80 per cent bulla, 10-25 per cent pumpkin and 10-40 per cent amaranth flour. Nutritional and sensory qualities of the formulations were investigated using standard methods.

Findings

Ash, fat and protein contents increased from 1.1-2.8 g/100 g (p < 0.001), 1.7-3.9 g/100 g (p < 0.001) and 6.1-9.0 g/100 g (p < 0.001) respectively with the increased amaranth flour. Crude fibre content increased with increasing percentage of the amaranth and pumpkin flours. On the other hand, carbohydrate content increased from 78.2 to 84.3 per cent (p < 0.001) with an increase of bulla flour. A significant increase in Fe, Zn and Ca from 6.8-10.5 (p < 0.01), 1.5-3.0 (p = 0.022) and 1.8-148.5 mg/g (p < 0.001) respectively was achieved with an increase in amaranth ratio in flour. The total carotenoid content increased with increase in the percentage of pumpkin flour. The best sensory attributes of the developed product were around the centre point of the three ingredients.

Originality/value

The study showed that a product with good nutritional value and sensory acceptability could be prepared from enset-based ingredients and the optimal product was obtained by blending 57.8 per cent bulla, 18.9 per cent pumpkin and 23.3 per cent amaranth flour. The enriched flour can have application for snack food preparation.

Abstract

Purpose

The present work reviews the impacts of the Covid-19 pandemic on architecture education (AE), with the aim of discussing the interaction and integration of technology-based models.

Design/methodology/approach

Different research methods were used to achieve the research purposes including an online survey, semistructured interviews, observations and reviewing recent literature. The study proposes a theoretical framework to investigate blended learning (BL) approaches in AE, based on the blended teaching–learning continuum, the growth of online delivery mode and technology integration and the gradual responsibility adopted for the current Covid-19 pandemic.

Findings

The study proposes a vision to reimagine post-Covid-19 education and the required BL strategy to provide a theoretical framework that integrates the instructional models required to be investigated by instructors.

Research limitations/implications

The research findings are based on a theoretical approach not tested practically. A further detailed investigation is required. Thus, the road to reimagining the post-Covid-19 AE is still evolving.

Social implications

As faculty members, one should take steps toward preparing BL strategies. These strategies present other alternatives to continue teaching and learning while keeping safe in any other emergency in education. In this work, an overview of BL approaches, continuum and related technological and instructional models has been shaped to propose a new vision to post-Covid-19 AE.

Originality/value

This paper responds directly to the initiated call on the pandemic's effect on traditional education by taking a pedagogical perspective. The study presents a holistic BL strategy and proposes a new theoretical and instructional model to design a suitable and balanced BL environment in AE.

Abstract

Purpose

In this work, the blends of poly(methyl methacrylate), PMMA and poly(methyl vinyl ether-alt-maleic acid monoethyl ester), PMVEMA-ES are studied as organic coatings to evaluate the impact of intermolecular hydrogen bonding on the physical and thermal characteristics of the prepared coatings.

Design/methodology/approach

PMMA (Mw = 120,000 g mol-1) was chosen as our binder material. Due to the low adhesion property of PMMA on polar substrates, it was blended with PMVEMA-ES, which contains polar –COOH groups, to improve the adhesion and thermal properties of the coatings by forming intermolecular hydrogen bonds. A cross-hatch adhesion test was carried out to evaluate the adhesion strength of different ratios of PMMA/PMVEMA-ES blends as coatings. In addition, changes in the glass-transition temperature, Tg as the composition varies were studied using Differential Scanning Calorimetry, DSC. Then, glossiness and hiding power tests were also conducted to evaluate the physical properties of the prepared coatings.

Findings

Upon a closer look at the DSC results, it was found that blends consisting of 12.5, 25.0 and 87.5 wt. % PMMA were completely compatible due to the presence of only a single Tg in their thermograms. Other blend compositions showed two distinct Tgs, indicating partial compatibility. Furthermore, the addition of PMVEMA-ES caused the Tg of PMMA to shift to lower temperatures, a strong indication of intermolecular hydrogen bonding interactions between the two components. From the cross-hatch adhesion results, the addition of PMVEMA-ES improved the adhesion properties of PMMA coating, except for blends consisting of 62.5 and 75.0 wt. % PMMA possibly due to the partial incompatibility between the two components. These findings were further corroborated with the results of glossiness and hiding power measurements. The superior result was seen for the blend consisting of 12.5 wt. % PMMA with strong adhesion property, high glossiness, compatibility and high translucency.

Practical implications

PMVEMA-ES can potentially be used as an adhesion promoter in PMMA-based coating formulations.

Originality/value

This is the first report on the properties of PMMA/PMVEMA-ES blends as coatings.

Abstract

Purpose

This study aims to investigate the effects of quality blended learning systems (QBLS) on the improvement of undergraduate students’ skills through the use of the Technology Acceptance Model (TAM) and the Theory of Planned Behaviour (TPB) model.

Design/methodology/approach

The study sample includes 1,200 subjects of which 126 and 1,074 are lecturers and students, respectively. The subjects were selected from seven post-secondary institutions in Nigeria. A stratified sampling technique was used in data collection. Collected data were analysed using exploratory and confirmatory factor analyses.

Findings

The results reveal that QBLS influences the perceived ease of use, perceived usefulness, attitude, subjective norms and perceived behavioural control towards intentions that culminate in the usage of blended learning tools (BLTs).

Originality/value

The study supports the belief that QBLS enhances users’ behaviour towards system usage with the TAM and the TPB predicting real usage of BLTs via users’ intentions. Practically, teachers should adjust the existing BLTs not only to create new ones but also to suit personalized teaching and learning activities.

Abstract

Purpose

Vast areas have been studied toward combustion and emission analysis in vegetable oil methyl esters and quite a few in algal oil biodiesel. To analyze the better alternate source for diesel engine, this study aims to investigate the combustion behavior and emission characteristics between cottonseed biodiesel and algal oil biodiesel on comparison with mineral diesel in a compression ignition engine.

Design/methodology/approach

The fuel properties like density, kinematic viscosity, calorific value and Cetane number have met the biodiesel standards for both algal and cottonseed biodiesel. At rated power, engine was operated on all three test fuels, where combustion analysis describing in-cylinder pressure, peak pressure, rate of pressure rise and rate of heat release and emission characteristics including hydrocarbon (HC), carbon monoxide (CO), oxides of nitrogen (NOx) and smoke for both biodiesel comparing mineral diesel.

Findings

Algal and cottonseed biodiesel showed up to 2-3°CA delayed start of combustion comparing mineral diesel curve. The in-cylinder pressure of algal biodiesel was found to be 68 bar, whereas cottonseed biodiesel exhibited 65 bar at full load condition. Similarly, the rate of pressure rise and rate of heat release of algal biodiesel depicted 7.9 and 10.7 per cent rise than cottonseed biodiesel, respectively. As the load increased, ignition delay showed decreasing trend, while combustion duration showed an increasing trend. HC, CO and smoke emissions were seen to be lower than mineral diesel with noticeable increase in NOx emission.

Originality/value

In this present investigation, biodiesel from Stoechospermum Marginatum, a marine marco algae, was used to fuel the compression ignition engine. Its combustion behavior and emission characteristics are compared with cottonseed biodiesel, a vegetable oil-based biodiesel having similar physio-chemical characteristics to understand the suitability of algal biodiesel in compression ignition engine. This study involves the assessment of straight biodiesel from macro algae and cottonseed oil on standard operating conditions.
