This study aims to systematically review the literature on happiness at work (HAW) by analysing existing studies, identifying relevant themes in HAW research and evaluating the methodologies used in the literature.

The study used a systematic review process, following the guidelines and principles outlined in the updated Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement 2020 and checklist. Articles were collected from six databases: Emerald insight, Taylor & Francis Online, Science Direct, Wiley Online Library, Springer and MDPI. Subsequently, systematic review was performed on 41 HAW articles published in 29 different journals between 2010 and 2022. The authors only considered articles that were either indexed by Scopus or in the Academic Journal Guide (AJG) list.

The study identified six major themes, assessed the operationalisation of HAW and analysed the research methodologies and statistical tools used in the sample studies. Majority of the articles discussed the antecedents of HAW followed by the HAW as a mediator. There is a high heterogeneity in the operationalisation of HAW in the reviewed articles. Moreover, majority of the studies have prioritised service sectors over the industrial sectors.

This study represents the first comprehensive review of the existing literature on HAW by using a systematic review methodology.

The purpose of this paper is to examine the direct and indirect effects of demographic factors on employee compensation, job satisfaction and organizational commitment in private higher educational institutes in Bangladesh. Specifically, how do compensation structure and job satisfaction mediate in the link between demographic factors and organizational commitment? To answer this question, a theoretical framework using the theory of employee retention provided by Martin and Kaufman, as its basis was established.

Data (n = 515) were collected from faculty members of the private universities in Bangladesh. Structural equation modeling was used to analyze the data.

Findings indicate that though demographic factors have no direct impact on organizational commitment, they have indirect impacts on organizational commitment through the mediation of compensation structure and faculty job satisfaction. Besides, compensation structure also has a significant mediating role in the link between demographic structure and faculty job satisfaction.

One possible drawback is the number of private universities from which the data were collected. In the sample used here, only 20 private universities were selected to conduct the survey. Besides, the study could not include public universities that are also a significant part and parcel of higher education in the country. So, if more private and public universities were taken into consideration to collect the data, the results might be improved. Thus, the usual cautions about overgeneralizing findings from this sample, to populations for which it is not strictly representative, apply.

From a practical perspective, as a cumulative body of work on organizational commitment, we will be better able to advise policymakers and educators on the elements they need to address to increase the longer engagement of the faculty members in their institutes. In this study, the one area of findings that may help policymakers and educators the most concerns compensation package that affects job satisfaction and organizational commitment. We found that demographic factors and compensation packages are the most important factors for the faculty members to impact on organizational commitment in this study.

The social implication is that policymakers of the private universities can focus on fair justice in terms of demographic factors and compensation package for job satisfaction, motivation and organizational commitment of the faculty members in their universities.

The findings of the study are important for the policymakers of the higher education institutes.

This research aims to use meta-analytical structural equation modeling to look into how hospitality employees use technology at work. It further investigates if the relationship between the constructs of the technology acceptance model (TAM) is moderated by job level (supervisory versus non-supervisory) and different cultures (eastern versus western).

In total, 140 relationships from 30 empirical studies (N = 6,728) were used in this study’s data analysis in accordance with the preferred reporting items for systematic reviews and meta-analysis.

The findings demonstrated that perceived usefulness had a greater influence on “user attitudes” and “acceptance intention” than perceived ease of use. This study also identified that the effect sizes of relationships among TAM constructs appeared to be greater for supervisory employees or in eastern cultures than for those in non-supervisory roles or western cultures.

The findings provide valuable information for practitioners to increase the adoption of employee technology. Practitioners need to focus on the identification of hospitality employee attitudes, social norms and perceived ease of use. Moreover, hospitality practitioners should be cautious when promoting the adoption of new technologies to employees, as those at different levels may respond differently.

This is the very first empirical investigation to meta-analyze the predictive power of the TAM in the context of hospitality staff technology adoption at the workplace. The findings also demonstrated differences in the predictive power of TAM constructs according to job level and cultural differences.

The purpose of this paper is to investigate the awareness of non-Muslims coming from a non-Muslim-majority country regarding Islamic financial services, in particular, the takaful products.

This paper uses structured questionnaires to acquire and understand South Korean citizens’ perceptions of Islamic financial services (primarily takaful) to reinforce the scant previous literature in this area of research. The questionnaires are developed and adapted based on a previous study by Htay and Salman (2013). The sample consisted of 121 Korean people who were living in Ampang, a popular suburb for South Koreans in Kuala Lumpur.

The findings indicate that even South Korean citizens who have dwelled in Malaysia for a significant amount of time had little awareness of Islamic financial services. Upon personal explanation about the product, however, they showed a significant interest to get to know about takaful and a willingness to subscribe to it in the near future.

Respondents are limited to only South Koreans who are residing in Malaysia.

Understanding the level of awareness about Islamic financial services among non-Muslims residing in Muslim-majority country.

There is ample scope to penetrate the non-Muslim market for Islamic financial products.

There is a growing concern over the lack of research in the area of perceptions of Islamic financial services among non-Muslims from non-Muslim-majority countries. The lack of study in this area of research has often been overshadowed by research studies on perceptions of Islamic financial services among non-Muslim residents in Muslim-majority countries, which may have led to a dearth of proper strategies in the Islamic financial industry to penetrate non-Muslim-majority markets.

The COVID-19 pandemic emphasises the need for antiviral materials that can reduce airborne and surface-based virus transmission. This study aims to propose the use of additive manufacturing (AM) and surrogate modelling for the rapid development and deployment of novel copper-tungsten-silver (Cu-W-Ag) microporous architecture that shows strong antiviral behaviour against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

The research combines selective laser melting (SLM), in-situ alloying and surrogate modelling to conceive the antiviral Cu-W-Ag architecture. The approach is shown to be suitable for redistributed manufacturing by representing the pore morphology through a surrogate model that parametrically manipulates the SLM process parameters: hatch distance (h_d), scan speed (S_s) and laser power (L_p). The method drastically simplifies the three-dimensional (3D) printing of microporous materials by requiring only global geometrical dimensions solving current bottlenecks associated with high computed aided design data transfer required for the AM of porous materials.

The surrogate model developed in this study achieved an optimum parametric combination that resulted in microporous Cu-W-Ag with average pore sizes of 80 µm. Subsequent antiviral evaluation of the optimum architecture showed 100% viral inactivation within 5 h against a biosafe enveloped ribonucleic acid viral model of SARS-CoV-2.

The Cu-W-Ag architecture is suitable for redistributed manufacturing and can help reduce surface contamination of SARS-CoV-2. Nevertheless, further optimisation may improve the virus inactivation time.

The study was extended to demonstrate an open-source 3D printed Cu-W-Ag antiviral mask filter prototype.

The evolving nature of the COVID-19 pandemic brings new and unpredictable challenges where redistributed manufacturing of 3D printed antiviral materials can achieve rapid solutions.

The papers present for the first time a methodology to digitally conceive and print-on-demand a novel Cu-W-Ag alloy that shows high antiviral behaviour against SARS-CoV-2.

The purpose of this paper is to evaluate the antioxidant activity and toxicity of Clinacanthus nutans leaves from three conventional extraction methods, i.e. maceration, Soxhlet and magnetic stirring.

Total flavonoid content (TFC) and phenolic content (TPC) were determined using colorimetric method of aluminum chloride and Folin-Ciocalteu (FC) assay, respectively. Antioxidant property of C. nutans was evaluated using 2,2'-diphenyl-1-pierylhydrazyl (DPPH) free radical scavenging assay. Cytotoxic activity of C. nutans against brine shrimp was evaluated based on LC50 (lethality concentration) after 24 h exposure to the plant extract.

The highest TPC of C. nutans was observed with Soxhlet extraction method (98.87 ± 10.43 mg of gallic acid equivalents (GAE/g) followed by maceration (68.77 ± 2.45 mg of GAE/g) and magnetic stirring (46.75 ± 2.45 mg of GAE/g). Interestingly, remarkable highest TFC was observed with magnetic stirring (568.90 ± 4.85 mg of rutin equivalent (RE)/g) followed by maceration (249.60 ± 2.79 mg of RE/g) and Soxhlet (174.8 ± 1.74 mg of RE/g). On the other hands, the extract obtained using maceration method showed the highest antioxidant activity (IC50: 14.18 mg/mL compared to ascorbic acid 144.36 µg/mL). Cytotoxicity of C. nutans from all extraction methods showed similar LC50 values with maceration (3.81 mg/mL), Soxhlet (2.61 mg/mL) and magnetic stirring (4.56 mg/mL), respectively.

Both phenolic and flavonoids are responsible for the antioxidant activity, of C. nutans extracts. Based on Meyer's toxicity index, all extracts were nontoxic (LC50>1 mg/mL).

The purpose of this study is to examine the factors that influence capital structure, profitability and stock returns and the relationship between capital structure, profitability and stock returns. The endogenous variables in this study are capital structure, profitability and stock returns, whereas the exogenous variables are firm size, growth opportunity, tangibility, liquidity, volatility and uniqueness.

The population used is a company that is listed on the compass index 100 period of August 2016. A total of 64 companies are sampled in this study. The unit of analysis is 448 data. The data analysis technique used is path analysis with the help of AMOS.

The results obtained show only profitability variables that affect stock returns. Variable capital structure, firm size, growth opportunity, tangibility and liquidity have no significant effect. Variables that influence capital structure are only influenced by growth opportunity, whereas other variables are not significant and variables that affect profitability are firm size, growth opportunity, uniqueness and volatility.

Path analysis is a model similar to the multiple regression analysis, factor analysis, canonical correlation analysis, discriminant analysis and more general multivariate analysis groups. This research discusses that capital structure is useful for increasing the value of the company in the sense that the more debt that is used, a tax deduction will be obtained because of interest costs. So that the company’s profits will increase and eventually will increase the value of the company. This opinion remains a controversy among financial experts. Until now, there is no agreement that can explain the capital structure in all conditions of the company. There are two important theories concerning capital structure, trade-off theory and pecking order theory.

Increased evidence for the health benefits of probiotics for health restoration coupled with the consumer's inclination towards a safe, natural and cost-effective substitute for drugs have led application of probiotics as a pharmaceutical agent and are rapidly moving in clinical usage. In this context, this article attempts to highlight the potential of probiotics as a pharmaceutical agent.

Endeavor has been made to explore the significance of probiotics for the modulation of gut ecology and their action. Potentiality of probiotics for their exploitation as a pharmaceutical agent has also been justified. Limitations of probiotic therapy and the various considerations for probiotic therapy have also been delineated.

Probiotic organisms influence the physiological and pathological process of the host by modifying the intestinal microbiota, thereby affecting human health. Beneficial effects of probiotics as a pharmaceutical agent seem to be strain and dose dependent and more efficacious with their early introduction. Combination of various probiotics proved to be more efficacious than single strain for exhibiting prophylactic activities.

Reviewed literature indicated that it is difficult to generalize for the beneficial effect of all probiotics for all types of diseases as efficacy of probiotics is strain-dependent and dose-dependent and its clinical application needs long-term investigations.

Clinical trials have displayed that probiotics may alleviate certain disorders or diseases in humans especially those related to gastro-intestinal tract.

Ingestion of fermented dairy products containing probiotic cultures may provide health benefits in certain clinical conditions such as antibiotic-associated diarrhoea, rotavirus-associated diarrhoea, inflammatory bowel disease, inflammatory bowel syndrome, allergenic diseases, cancer, Helicobacter pylori infection and lactose-intolerance. Application of probiotics as a pharmaceutical agent is recommended.

This paper explores the strategies adopted by purchasing firms to streamline relationships with suppliers amid the COVID-19 outbreak.

This study employed a multiple case study method and conducted 42 semi-structured interviews with procurement managers from six firms in the United Arab Emirates.

This study reveals six helpful strategies that purchasing firms can undertake to streamline supplier relationship management (SRM) in the wake of COVID-19. Precisely, purchasing firms are revising supply chain costs, planning orders in advance, sharing critical information with suppliers, planning major contingencies, developing a robust relationship with suppliers (e.g. partnership) and finally, improving the supplier's visibility.

This study comes with certain limitations. First, the results are based on a limited number of 42 interviewees. Hence, the study’s results cannot be generalized to a broader population. Second, the data were collected based on the cause and effect relationship.

The findings of this study can help purchasing firms learn and use new appropriate strategies to manage the relationship with their suppliers in the midst of the COVID-19 outbreak.

This study contributes to SRM literature by unveiling six distinct strategies (such as revising supply chain costs, planning orders in advance, sharing critical information, etc.) that purchasing firms have employed to develop a robust and healthy working relationship with the suppliers in the midst of the COVID-19 outbreak.

This research explores the mediating role of a firm's innovativeness and customer orientation on the relationship between commercial success and total quality management (TQM) in the Indian SaaS (Software-as-a-Service) sector.

The hypotheses suggested for this study were validated using partial least squares-based structural equation modeling on data collected from 189 executives working in SaaS companies in India.

The findings of this study revealed that a SaaS company's innovativeness fully mediates the relationship between TQM and corporate performance, whereas the customer orientation of SaaS companies partially mediates the relationship between TQM and corporate performance.

Findings of this paper indicate that, in addition to TQM deployment, SaaS companies' innovativeness and customer-focused strategy will improve their corporate performance. With minimal research focusing on India, this study may be considered a pioneer work. It can serve as a basis for SaaS company promoters to improve their corporate performance by implementing TQM processes.
