The purpose of this paper is to numerically model convective drying of a two‐dimensional iron ore pellet subjected to turbulent flow.

Abstract

Purpose

The purpose of this paper is to numerically model convective drying of a two‐dimensional iron ore pellet subjected to turbulent flow.

Design/methodology/approach

Simulations of the iron ore pellet drying process are carried out with commercial computational fluid dynamics software. The moisture distribution inside the pellet is calculated from a diffusion equation and drying due to evaporation at the surface is taken into account.

Findings

The results show an initial warm up phase with a succeeding constant rate drying period. Constant drying rate will only be achieved if the surface temperature is constant. The falling rate period will subsequently start at the forward stagnation point when the minimum moisture content is reached, while other parts of the surface still provide enough moisture to allow surface evaporation. The phases will thus coexist for a period of time.

Research limitations/implications

Owing to the complex physical processes involved in iron ore pellet drying, some parameters in the model are based on estimations. The effective diffusivity should, for example, in the future be investigated more thoroughly. It is also important to extend the model so that the falling rate drying period is also included. The model is at present undergoing further validation.

Practical implications

The simulations can provide detailed information on some key fluid dynamics and physical processes that an iron ore pellet undergoes during drying.

Originality/value

The simulations enhance the understanding of iron ore pellet drying and the model provides a complement to experimental investigations when optimizing the drying process.

The purpose of this paper is to develop a performance measurement model for the entire supply chain that includes balanced set of performance measures.

Abstract

Purpose

The purpose of this paper is to develop a performance measurement model for the entire supply chain that includes balanced set of performance measures.

Design/methodology/approach

The conceptual model was validated empirically in case companies through semi-structured interviews and content analysis of documents.

Findings

Performance measures are important to companies in the natural gas (NG) supply chain to assess performance against set objectives in order to identify loopholes in performance. This is important in order to remain competitive. The research found that both financial and non-financial performance measures are employed by companies to measure performance. The results also indicate that six performance criteria of the conceptual model are vital to the NG supply chain. In addition, all identified measures under each of criteria impact on performance of the supply chain with customer service and financial criteria considered as most important.

Research limitations/implications

The empirical data collected from the NG supply chain in Ghana were relatively small; however, additional information was obtained from company data and relevant magazines. Also, getting through to specific target participant was a challenge due to busy work schedule but, in case companies where it proved impossible, other staff who were also involved in supply chain were interviewed instead.

Practical implications

This research provides a useful source of information on performance measures for practitioners in the NG industry who wish to measure performance of their supply chain. It also provides areas from which further and additional research can be carried out.

Originality/value

This research provides performance measures for the NG supply chain of Ghana. Typically, performance measures have been evaluated in discrete manufacturing supply chain, petroleum industry supply chain and oil industry supply chain. This research expanded on ideas from these studies and applied them in the NG industry.

This study aims to explore gender equality in school textbooks in Georgia.

Abstract

Purpose

This study aims to explore gender equality in school textbooks in Georgia.

Design/methodology/approach

The research had the following questions: To what extent are women and men visible and represented equally in school textbooks? How do school textbooks promote gender socialization of boys and girls to be treated equally in terms of power and privileges, superiority and inferiority? Do school textbooks promote critical thinking and analysis of gender issues and problems? The content analysis of the qualitative research method was used to answer the research questions.

Findings

The research revealed that males remain more visible in school textbooks; however, the authors mainly attempt to balance the gender representation in textbooks quantitatively. The textbooks do not socialize girls and boys as equals in power, privileges, superiority and inferiority. The textbooks do not provide room for discussing gender and social justice issues.

Originality/value

The study is an original work. The study contributes to the development of the field of multicultural education, as it develops the three levels model of gender socialization based on the empirical research data. The first, detection level, implies the visibility of both boys and girls equally in school textbooks. The second, the recognition level of gender socialization, acknowledges gender equality in occupations, activities and power and privileges. The third, the affirmation level, develops a critical understanding of gender issues and gender equality in society.

Abstract

Social entrepreneurship has played a significant role in reducing unemployment and poverty, fixing other social issues and environmental concerns. Although there is an increasing concern on social entrepreneurship by the public sector, practitioner and scholars, there are still limited studies on predicting the intention to become a social entrepreneur. Thus, investigating social entrepreneurship intention using a systematic literature review (SLR) approach is crucial due to the lack of systematisation and categorisation in this field. Therefore, this study aims to conduct a SLR to identify the antecedents of social entrepreneurial intention (SEI) used by the previous research. In this sense, this chapter carries out a systematic review of the literature on social entrepreneurship intentions. The review is guided by the PRISMA Statement (Preferred Reporting Items for Systematic reviews and Meta-Analyses). After the identification and screening process, only 56 articles were qualified for further analysis. This SLR focused on articles that are using quantitative research and in the English language published in Scopus. Although there is no limitation in the timeline, the search string results found that the related articles were published between 2010 and 2020. From the thematic analysis, nine main themes were found. The themes are categorised based on the antecedents of SEI used by previous research. There are nine antecedents found: (1) perceived desirability and feasibility, (2) attitude, subjective norms and perceived behavioural control, (3) prior experience, (4) emotional factors, (5) self-efficacy, (6) personality, (7) support systems, (8) skills and competencies and (9) motivational factors. Further analysis of the themes has resulted in ten sub-themes. This chapter's contribution includes offering a clearer picture of the antecedents of social entrepreneurial intention that is still at its infancy stage. Additionally, this chapter managed to identify the research gaps and proposed future research agenda.

Abstract

Purpose

The purpose of this paper is to present an explanatory model of the factors that determine parental support for possible entrepreneurial initiatives of the parents' children. This is one of the most important challenges to promote the next generation of entrepreneurs.

Design/methodology/approach

A perspective based on the theory of planned behavior (TPB) is adopted, and the model is extended to integrate the antecedents of personal attitude toward children's entrepreneurship. The model is tested on a sample of 400 parents.

Findings

Perceived behavioral control (PBC), namely the perception that parents have about the readiness of the children to be entrepreneurs plays the greatest effect on the intention of supporting children's entrepreneurial behavior. In addition, parents' perceptions of how people from the immediate surroundings value the children's possible entrepreneurial behavior are the second most influential variable in the parents' intention to support such behavior. Finally, a parent's personal attitude toward the parent's children's entrepreneurship is the third most relevant variable to explain intention to support, practically with the same weight as subjective norms (SNs).

Practical implications

The results seem to confirm the importance of entrepreneurship development policies that focus on family characteristics and mindsets rather than on more traditional formal institutional support, such as business advice or financial resources. Family emerges as a key mediator to transfer the rules of normative and cultural-cognitive dimensions. Moreover, the results indicate the important role of entrepreneurship education in enhancing entrepreneurship not only due to the positive direct impact on students' entrepreneurial intentions, but also by changing parents' perceptions regarding the children's capabilities and, therefore, influencing the support for entrepreneurial behavior.

Originality/value

Previous studies have analyzed the influence of support from the immediate environment, especially the family, on young people's entrepreneurial behavior and have defined the types of support the family environment can provide. However, there is a missing link in the literature regarding the determinants of family support, despite the determinants' importance in configuring the normative and cultural-cognitive dimensions and the determinants' impact on society, promoting entrepreneurship.

Abstract

Purpose

This study focuses on historic buildings and site preservation (HBSP), which forms part of cultural heritage amidst rampant demolishing and seeming neglect of such heritage in Ghana. The purpose of this study is to assess public awareness of the importance of HBSP in Kumasi.

Design/methodology/approach

The study combines qualitative and quantitative research methods. Primary data were collected through questionnaires and interviews based on a purposive sampling technique. Respondents were residents of Kumasi.

Findings

The study revealed that awareness of the importance of HBSP is dependent on the demographic variables. The young generation below 30 years seems more aware of the importance of HBSP.

Research limitations/implications

The study is limited by the fact that respondents were not willing to reveal income levels. Laws governing cultural heritage, including HBSP at the MMDAs, was not studied in detail and could be an area for further research.

Practical implications

This study brings out the need to be aware of the importance of HBSP and train staff to enforce laws governing HBSP in six metropolitan, municipal and district assemblies (MMDAs) as part of Ghana's urban regeneration. This study further raises awareness among residents for sustainable architectural heritage preservation in Ghana.

Originality/value

The concept of HBSP is not popular in Ghana. This academic paper apparently assesses the level of awareness of the importance of HBSP among residents in Kumasi with an aim to identify and train staff of MMDAs on laws governing HBSP.

Abstract

Purpose

The purpose of this study is to evaluate eTourism technology acceptance literature to illustrate current gaps in the field and suggest two alternative perspectives that could be adopted.

Design/methodology/approach

A review of academic literature in the field of eTourism technology acceptance was undertaken combining a systematic keyword-based search and snowballing techniques leading to the identification of relevant academic journal articles published since the year 2000.

Findings

While the field of eTourism technology acceptance research has grown substantially over the past few decades, this study highlights that the majority of this research seems to have been conducted within a narrow theoretical scope. The study suggests that this has led to contemporary theoretical and philosophical advancements in understanding the psychological, sociological and neuroscientific aspects of consumer behaviour not yet being mirrored in the eTourism technology acceptance research.

Research limitations/implications

This study invites researchers to adapt alternative theoretical perspectives to create a more in-depth understanding of aspects of technology acceptance behaviour that have yet to be understood. Two distinct alternative perspectives, NeuroIS and interpretivism, are suggested.

Practical implications

This study assists researchers in developing alternative research agendas and diversifying the theoretical foundations of eTourism technology acceptance research.

Originality/value

eTourism technology acceptance research risks being left behind if it does not begin to think beyond current theoretical conceptions of consumer behaviour research. This study contributes to the wider literature by highlighting how eTourism literature is falling behind and by suggesting two innovative alternatives that allow eTourism research an exciting way forward.

Abstract

Purpose

AI-based chatbots are revamping employee communication in organizations. This paper examines the adoption of AI-based employee experience chatbots by employees.

Design/methodology/approach

The proposed model is developed using behavioral reasoning theory and empirically validated by surveying 1,130 employees and data was analyzed with PLS-SEM.

Findings

This research presents the “reasons for” and “reasons against” for the acceptance of AI-based employee experience chatbots. The “reasons for” are – personalization, interactivity, perceived intelligence and perceived anthropomorphism and the “reasons against” are perceived risk, language barrier and technological anxiety. It is found that “reasons for” have a positive association with attitude and adoption intention and “reasons against” have a negative association. Employees' values for openness to change are positively associated with “reasons for” and do not affect attitude and “reasons against”.

Originality/value

This is the first study exploring employees' attitude and adoption intention toward AI-based EEX chatbots using behavioral reasoning theory.

Abstract

Purpose

This study aims to investigate the different attributes of electronic commerce (e-commerce) that determine perceived value and electronic loyalty (e-loyalty) among consumers of online food delivery applications (OFDAs). In this globalized world and competitive environment, e-commerce demands have increased and organizations are giving special attention to web development, website design and functions to hold the current consumers with sustainable performance in the globalized and competitive environment. Almost every industry has been affected by the coronavirus disease 2019 (COVID-19) and changed the way of operational work in many industries. Similarly, the food industry is facing serious challenges and now restaurants started heavily depending on OFDAs.

Design/methodology/approach

The study was quantitative and data were collected from 509 consumers of the district of Rawalpindi, Punjab Pakistan by using a convenience sampling technique who was the users of OFDAs to evaluate the proposed research model. Confirmatory factor analysis was applied to evaluate the validity of the constructs, and structural equation modeling was employed to test the model through Smart-PLS.

Findings

Our findings revealed that perceived value has a substantial positive impact on electronic loyalty (e-loyalty). Moreover, results confirmed that perceived value mediates the relationship of electronic privacy (e-privacy), electronic security (e-security), electronic payment (e-payment), usability and electronic innovativeness (e-innovativeness) with e-loyalty.

Research limitations/implications

This study added to the unified theory of acceptance and use of technology (UTAUT) and technology acceptance model (TAM) by exploring consumers’ intentions for using OFDAs in the framework of e-commerce attributes, perceived value and e-loyalty. Similarly, the study enabled the author to learn more about how people would use the information system after successfully applying the UTAUT.

Practical implications

This study has significant implications for web developers, application designers, food delivery companies, restaurants and other businesses. Subsequently, it indicates the importance of the incredible attractiveness of OFDAs in boosting users’ intentions to keep using the application.

Originality/value

This research contributes substantially to OFDAs efforts to continuously increase its meal service platform and improve client satisfaction which resulted in repurchase intent. In addition, the research facilitates OFDA firms to enhance the features of their applications according to clients.
