Abstract

Purpose

The purpose of this paper is to assess the feasibility of analytical models, specifically the radial basis function method, Akbari–Ganji method and Gaussian method, in conjunction with the finite element method. The aim is to examine the impact of processing parameters on temperature history.

Design/methodology/approach

Through analytical investigation and finite element simulation, this research examines the influence of processing parameters on temperature history. Simufact software with a thermomechanical approach was used for finite element simulation, while radial basis function, Akbari–Ganji and Gaussian methods were used for analytical modeling to solve the heat transfer differential equation.

Findings

The accuracy of both finite element and analytical methods was validated with about 90%. The findings revealed direct relationships between thermal conductivity (from 100 to 200), laser power (from 400 to 800 W), heat source depth (from 0.35 to 0.75) and power absorption coefficient (from 0.4 to 0.8). Increasing the values of these parameters led to higher temperature history. On the other hand, density (from 7,600 to 8,200), emission coefficient (from 0.5 to 0.7) and convective heat transfer (from 35 to 90) exhibited an inverse relationship with temperature history.

Originality/value

The application of analytical modeling, particularly the utilization of the Akbari–Ganji, radial basis functions and Gaussian methods, showcases an innovative approach to studying directed energy deposition. This analytical investigation offers an alternative to relying solely on experimental procedures, potentially saving time and resources in the optimization of DED processes.

Abstract

This chapter explores the approaches to digital representation of Australian Aboriginal art and visitor engagement in museum exhibition spaces from a digital design perspective. It discusses recent developments in the fields of digital representation of Aboriginal art, immersive exhibition design and visitor engagement. Through a case study of an immersive exhibition on Australian Aboriginal art in the National Museum of Australia, Canberra, this chapter identifies how Aboriginal art can be digitally represented by appropriate immersive technologies ranging from augmented realities [ARs] and virtual realities [VRs] to mixed reality [MRs] and extended reality [XRs] for enhancing visitors’ immersive digital experience. According to the analysis, the digital representation of Aboriginal artworks needs to be conducted practically, cognitively and ontologically based on understanding Australian Aboriginal history and culture. Visitors can engage with Aboriginal art stories meaningfully through immersive exhibitions through this holistic approach.

Abstract

Purpose

The objective of this study was to evaluate the technical-economic process efficiency of obtaining simultaneous lipo-soluble (LSF) and water-soluble (WSF) fractions from annatto seeds.

Design/methodology/approach

The batches of annatto seeds were submitted to the refrigerated solid-liquid extraction process in four stages: pre-extraction, aqueous extraction, separation by decantation and filtration. After that, LSF and WSF from annatto seeds were obtained. The process efficiency and the quality of LSF and WSF were analyzed in terms of average yield and bioactive compounds (bixin, norbixin, phenolics and flavonoids) and their antioxidant and antimicrobial activities. Furthermore, they were economically evaluated in terms of costs of manufacturing and profitability parameters.

Findings

The process was efficient in terms of overall average yield (LSF = 8.68% and WSF = 2.76%) (w/w) and in terms of quality, mainly with higher average yields of bixin (82.34% in LSF) and norbixin (29.59% in WSF) (w/w). The concentration of bioactive compounds in the fractions promoted an increase in inhibiting free radicals (DPPH* and ABTS*+) and in the ferric-reducing power (FRAP). LSF showed a minimum inhibitory concentration of 0.06 mg mL-1 for S. aureus and 0.13 mg mL-1 for S. Typhimurium and S. Enteritidis. The lowest manufacturing costs were obtained for the LSF due to its higher extraction yield compared to the WSF. Plants on an industrial scale of 100 and 1000 L were considered economically viable, with a return on investment of 5 and 2 years.

Originality/value

Thus, fractions (WSF and LSF) can be applied as natural additives, as sources of bioactive compounds for nutraceutical and/or pharmaceutical, and in the development of other innovative processes. These results have practical applicability for pharmaceutical and food industry.

Highlights

 

  1. Green processing of annatto seeds obtains fractions rich in antioxidant compounds.

  2. Efficiently presents a high yield of bixin and other bioactive compounds.

  3. Effective in concentrating compounds that inhibit microbial growth.

  4. Fractions are more accessible sources of bioactive compounds for isolation.

  5. Cost of manufacturing (COM) and profitability are studied.

Abstract

Purpose

The aim of this paper is to investigate the potential impact of Industry 4.0 (I4.0) digital technologies on promoting sustainability in small and medium-sized enterprises (SMEs) within developing economies such as Brazil. Additionally, we present a comprehensive framework that consolidates this correlation.

Design/methodology/approach

Qualitative research was conducted through semi-structured interviews with leaders of SMEs to identify the specific challenges in achieving sustainability. Additionally, interviews were conducted with technology provider firms to evaluate the existing solutions available to SMEs. The interview results were analyzed, and technological solutions were proposed through a focus group session involving four experts in I4.0. These proposed solutions were then compared with the offerings provided by the technology providers. Based on this, a second round of meetings was conducted to gather feedback from the SMEs.

Findings

The findings of this study confirm the feasibility of implementing I4.0 and sustainable practices in SMEs. However, it is crucial to tailor the technologies to the specific circumstances of SMEs. The study presents propositions on how specific applications of technology can address the economic, environmental and social demands of SMEs. Furthermore, a framework is proposed, emphasizing the integration of smart technologies as essential components across sustainability dimensions.

Abstract

Ecotourism is a sustainability approach that has emerged as an alternative to the negative environmental impacts of tourism, where natural, cultural and historical values are used as sources. Ecotourism is a nature-based tourism activity that ensures the sustainability of natural resources and promotes the economic development of local populations. It also preserves sociocultural values and protects the ecological system for future generations. However, if ecotourism is well-controlled, it can positively affect nature, natural life, local people and the local and national economy. This study highlights the importance of ecotourism for sustainability in the tourism industry. It examines ways to deal with the ecotourism phenomenon. In this direction, the study defines the concepts of ecological tourism and sustainability. It describes the general characteristics of ecotourism and sustainable tourism and the developing and potential environmental impacts associated with them. The study highlights that any tourist activity that does not have a sustainable quality cannot be long-term and will increase awareness on this topic.

The purpose of this research is to identify and test selected economic and organisational factors influencing the sustainability of participatory budgeting (PB) in Slovakia.

Abstract

Purpose

The purpose of this research is to identify and test selected economic and organisational factors influencing the sustainability of participatory budgeting (PB) in Slovakia.

Design/methodology/approach

The data were collected from websites and publicly available documents from all local governments with urban municipality status in Slovakia, for a total of 155 municipalities, 59 of which have established a participatory budget. The main method applied was correlation analysis.

Findings

The findings indicate: (1) a weak inverse correlation between debt level and the continuous existence of PB in municipalities; (2) a moderate direct correlation between the duration of PB in a municipality and integration of PB in its programme budgeting; (3) a moderate direct correlation between the duration of PB in a municipality and the political experience of the mayor.

Research limitations/implications

The findings are derived from a quantitative analysis of cases localised in a single country, and therefore interpretation requires an awareness of the context of local democracy in Slovakia. In this regard, any generalisation beyond the context under study needs to be considered with caution.

Originality/value

This research fills a gap in the role of PB in the context of sustainability, especially in the context of a post-communist country like Slovakia. It applies a quantitative approach to the analysis of PB, which is relatively rare in this field of study (qualitative case studies are predominant in PB research).

Abstract

Purpose

In this study, the researchers explored the roles played by digital technologies and digital innovation (DI) in Pakistan's Information, Communication and Technology (ICT) companies' firm performance (FP).

Design/methodology/approach

The researchers used a quantitative study to gather cross-sectional data from employees working in Pakistan's ICT companies. The authors based this study's findings on 396 valid samples.

Findings

The structural equation modeling (SEM) findings underline that digital capability (DC), digital orientation (DO) and digital transformation (DT) have positive and significant effects on DI and FP. Moreover, there is a positive and significant relationship between DI and FP. Finally, DI mediates DC's, DO's and DT's associations with FP.

Practical implications

By committing to embracing new digital technologies and updating existing DCs to become innovation leaders and to improve FP, the findings will help sectors to take advantage of developing digital technologies and the trend toward digitalization. The results are also valuable for policymakers when considering if SMEs should be provided with more money for the digital up-skilling of their employees. Finally, this study's findings enrich the depth of literature about companies' use of digital technologies.

Originality/value

This study's empirical findings confirm the roles played by DC, DO and DT in improving DI and FP in a developing country such as Pakistan.

Abstract

Purpose

This research aims to investigate the relationship between employer branding and its antecedent organisational culture within the context of the private banking sector. The study also investigates the relationship between employer branding and employee brand equity as a consequential construct. Additionally, the mediating role of trust and the moderating role of gender in the relationship between employer branding and employee brand equity has been examined.

Design/methodology/approach

The present study’s findings result from data analysis collected from a sample of 454 employees working in private banks in India. The data analysis was conducted utilising the structural equation modelling technique with the assistance of analysis of moment structures (AMOS) software.

Findings

The study’s findings indicate that supportive and bureaucratic (formal) culture in private banks exhibit a significant relationship with employer branding. However, the relationship between innovative culture and employer branding was found to be insignificant. The research also reveals a significant positive association between employer branding and employee brand equity variables: brand consistent behaviour, brand endorsement and brand allegiance. Further, the study highlights the mediating role of employee trust in management in the relationship between employer branding and employee brand equity. Examining demographic variables suggests that gender moderates the relationship between employer branding and employee brand equity.

Originality/value

The originality of this study lies in its exploration of the critical role of organisational culture variables in shaping employer branding within the context of private banks. The findings highlight that cultivating supportive and bureaucratic cultures can effectively enhance the employer branding of private banks. The study emphasises the outcomes of employer branding initiatives, signifying that they contribute to developing brand equity among employees. This leads to long-term employee commitment and advocacy towards the organisation, as employees become brand advocates for the bank with which they are affiliated. The study contributes to a better understanding of the relationship between organisational culture, employer branding and employee brand equity, providing valuable implications for the private banking sector aiming to reinforce their employer brand and increase employee engagement.

Abstract

Purpose

This study aims to assess service quality in sport child camps among both participants and parents and its effects on satisfaction and behavioural intentions.

Design/methodology/approach

Data were collected from participants (n = 258) and parents (n = 226) of a sport child camp. A confirmatory factor analysis analysed the psychometric properties of the constructs, and a subsequent structural equation model examined the effects of service quality on satisfaction and behavioural intentions.

Findings

The results indicate a multi-dimensional construct of service quality that influences satisfaction and behavioural intentions differently among parents and participants. For participants, Service Failures and Recovery, Safety and Food influenced satisfaction, while Service Failures and Recovery and Fun influenced Behavioural Intentions. For parents, Management Commitment to Service Quality, Staff, Food and Contact with Physical Environmental influenced satisfaction, while Management Commitment to Service Quality and Staff influenced Behavioural intentions.

Research limitations/implications

Both parents and participants' perceptions of service quality in sport child camps were captured and its effects on satisfaction and behavioural intentions. The study provides sport child camp managers with critical information about service delivery and its outcomes among the two key consumers (participants and parents).

Originality/value

This study offers new ideas to advance knowledge on sport child camps by capturing the perceptions of two key stakeholders and providing useful insights into how different attributes of service quality influence the levels of satisfaction and behavioural intentions among parents and participants.
