Abstract
The inverse heat conduction problem with many internal responses is considered. After discretization with respect to time, the problem is described by a system of the Helmholtz equations in a recurrent form. An approximate solution of a heat conduction problem in an integral form is shown. Then, an approximate solution of an inverse heat conduction problem in a flat slab is presented for many internal temperature responses. Stability of the solution with respect to the internal response errors is investigated for two cases: when the integrals are calculated with the use of the average value theorem and when they are calculated numerically. Analysis of the norm of a matrix that is essential for the solution stability shows that in the case of three sensors the norm slightly changes with change of the middle sensor location. If more than three sensors are taken into consideration, the results practically will not change comparing to the case of three sensors. The internal temperature response errors are suppressed if the time step is greater than a certain critical value.

Abstract
Purpose
This study aims to better understand the Islamic consumption incentives because the spectacular flourishing of the halal market in different places around the world has grown the interest in understanding and deciphering the mechanisms behind its development.
Design/methodology/approach
Through an exploratory study of some Tunisia-based Islamic groups’ purchasing behavior, this paper investigates factors leading to the purchasing of halal goods (Islamic consumption).
Findings
Findings show that the Islamic consumer is more of an Islamist than simply a Muslim. In addition, findings show that halal consumption is not merely related to religious affiliations but also the product of numerous cultural, social and psychological factors.
Originality/value
In addition to Islamism and Islamic activism, this paper puts in evidence the role of some post-structural factors such as identity, nostalgia and hedonism in relation to the buying intention of halal products and services.

Abstract
Purpose
The purpose of this research paper was the study of an affluent Islamic market, going through a rapid economic and social transformation, from an ethical consumption perspective. More specifically, impact of environmentalism, consumption ethics, fair trade attitude and materialism was investigated on the ethical consumption behaviour of Muslim consumers.
Design/methodology/approach
A research framework was put together after consulting relevant literature, Islamic scholars and Islamic marketers. The developed research framework was tested in the Islamic State of Qatar. As an outcome of an online questionnaire-based survey targeting Muslim (Qatari) consumers in a public university, 243 usable questionnaires were collected. After reliability and validity checks, AMOS SPSS 20 was used to conduct structural equation modelling analysis on the collected data.
Findings
The results showed consumption ethics, environmentalism and fair trade attitude as significant determinants of ethical consumption behaviour. There was an insignificant association between materialism and ethical consumption behaviour. The findings suggested that most Muslim consumers within this affluent market showed an interest in ethical consumption. However, an insignificant association between materialism and ethical consumption behaviour implied that even though Muslim consumers demonstrated ethical consumption behaviour, they were not anti-materialism. The outcome suggests that due to the high levels of affluence among Muslim consumers, it is possible that they may be practising ethical and materialistic consumption simultaneously.
Practical implications
This research should assist marketers in understanding the ethical consumption behaviour of Muslim consumers who are faced with ethical and materialistic consumption options within an affluent Islamic market.
Originality/value
The research should add to the body of consumer behaviour knowledge, as it provides an insight into the consumption behaviour of Muslims who are facing social and religious ideology conflicts which makes their ethical consumption behaviours more sophisticated.

Abstract
Purpose
This paper aims to investigate the motivations behind Muslim consumers’ boycotting of foreign products. The act of boycotting foreign products has become increasingly common among Muslim consumers. Products from different countries-of-origin are their boycott targets.
Design/methodology/approach
The study adopted semi-structured in-depth interviews and focus-group discussions for data collection. A total of 36 Indonesian subjects participated in the study, representing the “university student” and “non-university student” samples. Leximancer, a qualitative analytical tool, was used to identify important motivations for boycotting behaviour among Muslim consumers.
Findings
Contrary to previous findings, this study found that Muslim consumers do not boycott solely for religious reasons. For example, most participants reported they boycotted Chinese products because they would like to protect their local products, along with the religious-based motivation of rejecting uncertainty about the halal certification of the products. Thus, the motivations identified from this study were not related exclusively to religion.
Practical implications
The present study offers new insights into the religious and secular motivations of Muslim consumers’ boycotts. Foreign products should adopt localised strategies such as repeatedly reminding consumers of the true halal nature of their products and their contribution to the local people.
Originality/value
This study contributes to the recognition of new insights into Muslim motivation to boycott product. The results develop important concepts surrounding the issue of boycotting foreign products. A concept map has been produced to offer a more comprehensive picture of Muslim’s boycotting behaviour.
