Abstract

Purpose

The purpose of this paper is to describe a generic method and tool for assessing the reliability and robustness of the product development process.

Design/methodology/approach

By extending the integrated definition for function modelling (IDEF0)‐based modelling approach, the paper demonstrates how to calculate the effectiveness of the process and the quality of the process output based on the quality of inputs, the controls and the tools used within the process. To illustrate and validate the proposed approach, it is applied to a case study of a product development process incorporating incomplete, fuzzy and uncertain inputs and resources.

Findings

Demonstrates the effectiveness of the tool in providing a quantified assessment of the process as well as its ability to identify those critical areas which will yield a significant improvement in the outcome of the product development process.

Originality/value

The technique is a valuable tool to assess the robustness and sensitivity of the process to changes in the quality of inputs, controls and tools, and can be integrated into businesses processes and management systems, and used as a tool to support continuous business and manufacturing decisions at any point of time.

Abstract

Purpose

The purpose of this paper is to examine outcome of activation energy in rotating flow of an Oldroyd-B nano liquid.

Design/methodology/approach

Flow is generated due to stretched surface. Binary chemical reaction is studied. Brownian and thermophoresis effects are considered. The system of nonlinear ordinary differential equations is derived. Convergent series solutions are obtained by homotopy analysis method. The resulting expressions for velocities, temperature and concentration are computed for different embedded parameters.

Findings

It is found that velocities f′ and g  have decreasing effect when rotation parameter is enhanced. Brownian and thermophoresis are increasing functions of temperature and concentration. The physical quantities are sketched and discussed numerically. Concentration and temperature fields show decreasing behavior via Brownian and thermophoresis parameters.

Originality/value

Authors investigate the Rotating flow of Oldroyd-B nano fluid with chemical reactions. This work is not done yet in literature.

Abstract

Purpose

Intelligent tutoring systems (ITS) are a supplemental educational tool that offers great benefits to students and teachers. The systems are designed to focus on an individual’s characteristics, needs and preferences in an effort to improve student outcomes. Despite the potential benefits of such systems, little work has been done to investigate the impact of ITS on users. To provide a more nuanced understanding of the effectiveness of ITS, the purpose of this paper is to explore the role of several ITS parameters (i.e. knowledge, system, service quality and task–technology fit (TTF)) in motivating, satisfying and helping students to improve their learning performance.

Design/methodology/approach

Data were obtained from students who used ITS, and a structural equation modeling was deployed to analyze the data.

Findings

Data analysis revealed that the quality of knowledge, system and service directly impacted satisfaction and improved TTF for ITS. It was found that TTF and student satisfaction with ITS did not generate higher learning performance. However, student satisfaction with ITS did improve learning motivation and resulted in superior learning performance. Data suggest this is due to students receiving constant and constructive feedback while simultaneously collaborating with their peers and teachers.

Originality/value

This study verifies that there was a need to assess the benefits of ITS. Based on the study’s findings, theoretical and practical implications are proposed.

Abstract

The unique characteristic of Islamic bank leads in governance and disclosure. Using stakeholder, signaling, and market discipline theory, governance and adequate disclosure may increase bank soundness. This study aims to investigate the relationship of sharia disclosure and Sharia Supervisory Board in influencing Islamic bank soundness in the different regulatory framework of the country. Using purposive sampling, the research covered 84 Islamic banks in 16 countries during the period 2013–2015 with lag data of Islamic bank soundness. The result shows sharia disclosure influences on Islamic bank soundness for management efficiency, capital adequacy ratio, asset quality, and liquidity. The results also show that sharia disclosure mediates the indirect effect of SSB on Islamic bank soundness. The regulatory framework (sharia accounting standard and SSB regulation) shows moderating effect of regulation framework proved on the association of sharia disclosure with management efficiency, capital, and liquidity. The effect is indirectly depending on the regulatory framework for proxy management efficiency, capital, and liquidity. The implication of the research suggests that sharia disclosure could increase the market discipline mechanism of Islamic bank stream. The Islamic bank can increase the transparency using sharia disclosure as a branding for increasing public trust, even though in the deficient Islamic bank regulation countries.

Abstract

Purpose

The purpose of this paper is to explore the impact of COVID-19 lockdown on micro-businesses owned by women borrowers of microfinance institutions and to provide policy suggestions to assist women entrepreneurs in managing such an unexpected crisis from a qualitative perspective within developing countries such as Pakistan.

Design/methodology/approach

The study adopts a qualitative research design to explore the impact of COVID-19 on women’s entrepreneurial activities. Seven women entrepreneurs were selected and semi-structured interviews with focused group discussion under case study research design are used. Thereby providing a contemporary view of the issues faced by women entrepreneurs in the period of huge social and economic upheaval.

Findings

The results provide valuable insights about how the COVID-19 crisis affected women entrepreneurs by particularly considering household income, business sales, lifestyle and mental health. The liquidation of women-led businesses indicated the necessity to reconsider creativity and digitalization for business survival. Moreover, the results also revealed that the impact of the COVID-19 pandemic on the physical, mental and economic well-being of women highlights the need for considering gender gap issues in forming response policies for COVID-19 in developing countries.

Originality/value

As the COVID-19 crisis is a recent and existing phenomenon, this study is among the first to explore particularly the impact of the COVID-19 outbreak on micro-enterprises mainly owned and managed by women. Thereby claiming that COVID-19 not only physically but also psychologically affected women entrepreneurs. Moreover, the study highlights a need of skill focused training programs for women entrepreneurs to make sure that they can protect their businesses during such difficult times.

Abstract

Purpose

The purpose of this study is to study flow caused by rotating frame. Effects of Darcy–Forchheimer and porous medium are considered to study velocity field. Concentration field is discussed in presence of activation energy. Darcy–Forchheimer in a rotating frame is examined. Flow because of stretched sheet fills the porous space. Binary chemical reaction is entertained. Resulting system is numerically solved. The plots are arranged for rotational parameter, porosity parameter, coefficients of inertia, Prandtl number and Schmidt number. It is revealed that rotation on velocity has opposite effects when compared with temperature and concentration distributions. Skin friction coefficients and local Nusselt and Sherwood numbers are numerically discussed.

Design/methodology/approach

Darcy–Forchheimer in a rotating frame is examined. Flow because of stretched sheet fills the porous space. Binary chemical reaction is entertained. Resulting system is numerically solved. The plots are arranged for rotational parameter, porosity parameter, coefficients of inertia, Prandtl number and Schmidt number. It is revealed that rotation on velocity has opposite effects when compared with temperature and concentration distributions. Skin friction coefficients and local Nusselt and Sherwood numbers are numerically discussed.

Findings

The major findings here are as follows: an addition in porosity λ causes decay in velocity f′(η) while there is opposite behavior for temperature θ(η) and concentration ϕ(η) fields. θ and ϕ via β have similar results qualitatively. There is an opposite behavior of Pr on temperature and concentration. Inverse behavior of λ on ϕ and wall mass flux is noted. Concentration ϕ is decreasing function of reaction rate constant σ. Skin friction coefficient has similar qualitative results for λ and β. Temperature gradient −θ(0) is decreased by λ and β.

Originality/value

Here, the authors are interested to investigate rotating flow in a porous space. Dissipation and radiation effects are neglected. Effects of activation energy are studied. This work is not done yet in literature.

Abstract

Purpose

The purpose of this study was to evaluate food handling practices and food safety knowledge among undergraduate students in the Republic of Serbia. It was also to determine whether the university curriculum influences the food safety outcome among participating students.

Design/methodology/approach

A structured, self-administrative questionnaire was designed and used to assess the level of food handling practices and food safety knowledge among undergraduate students in the Republic of Serbia. In total, 240 students were involved in this study. For each participating student, the food handling practice score (FHPS) and food safety knowledge score (FSKS) was calculated by dividing the sum of correct answers by the total number of correct responses. Additionally, knowledge gaps among students of food/health related and non-food/health related faculties were identified.

Findings

The average FHPS for all students was 46%, while the average FSKS was 56%. Both FHPS and FSKS scores were significantly associated with the education, and students of food/health related faculties (Food Technology, Veterinary Medicine and Medicine) obtained better scores compared to students of non-food/health related faculties (Faculty of Agriculture, Economics and Faculty of Philology). Only 12.5% of all students and only 3.3% of non-food/health related students knew that food contaminated with food poisoning bacteria cannot be recognized by visual, olfactory or taste checks. The results indicated that 95% of students apply good practice of hand hygiene before preparing food, while only 52.5% of all students declared that they wash their hands for at least 20 s.

Originality/value

This is the first research aimed to investigate the food handling practices and food safety knowledge among undergraduate students in this part of Europe. Identifying knowledge gaps can help identifying at-risk populations and knowledge-based interventions. Also, novelty of this research was the connection between students' knowledge and curriculum of different food/health related faculties.

Abstract

The study examines the effects of governance quality and religiosity on tax evasion (TE) in the OECD (Organisation for Economic Co-operation and Development) countries. Further, the study investigates which government qualities and religiosities affect TE significantly. Ordinary least squares has been used to analyze the data gathered from 36 OECD countries covering the period of 2002–2015 based on the latest data of TE. The results show the negative impact of governance quality and religiosity on TE; it implies the higher level of governance quality and religiosity, and the lower level of TE across the countries. Among the governance qualities, the higher the government effectiveness (GE), the rule of law (RL), and regulatory quality (RQ), the lower the level of TE as they have a negatively significant impact on TE. On the contrary, the positive impact of the voice of accountability (VA) and political stability (PS) on TE implies that with increasing the VA and PS, TE also increases. Moreover, during the investigation of religiosities on TE, the study found that Catholics (CATH) have a significant and negative effect on TE, while Muslim (MUSL) is found to be positively significant. Overall findings of the study suggest the government of the OECD countries to emphasize enhancing the governance quality and practicing of peoples' religious activities freely, which demotivates people to evade tax.

Abstract

Purpose

The purpose of this paper is to evaluate the levels of food safety knowledge, attitudes and practices (KAP) of food technical assistants (FTAs) working in dairy processing plants (DPPs) with different grades of prerequisite programs (PRPs) checklist.

Design/methodology/approach

An observational cross-sectional study was carried out by using a self-administered questionnaire and interviewing 76 FTAs occupied in DPPs in the city of Isfahan, Iran.

Findings

Out of a total score of 100, the participants received scores for knowledge (79.5 ± 14.9), attitudes (75.2 ± 9.9) and practices (86 ± 11.6) referred to the principles of Hazard analysis Critical Control Point (HACCP). It was found correlations between food safety knowledge and attitudes of FTAs (r = 0.38, p ≤ 0), knowledge and practices (r = 0.21, p = 0.03) and between attitudes and practices (r = 0.36, p ≤ 0). Moreover, there were also significant correlations between KAP scores and age (knowledge: r = 0.18, p = 0.06; attitude: r = 0.25, p = 0.01; practice: r = 0.22, p = 0.02) and KAP scores and job satisfaction level (knowledge: r = 0.27, p = 0. 01; attitude: r = 0.22, p = 0.02; practice: r = 0.27, p = 0). There was no significant correlation between educational background and KAP scores. Furthermore, no significant correlation was found in terms of gender.

Originality/value

Education of FTAs about food safety issues seems necessary. Such training should not only focus on theoretical aspects of knowledge but also be practical to foster positive attitudes toward food safety and promote practices among FTAs. Consideration to all principles of PRPs is recommended to implement food safety management system (FSMS) in food processing plants (FPPs).
