Abstract

Purpose

The primary objective of this study is to examine how trust and religiosity, in relation to halal products, impact Turkish consumers' intention to purchase such goods. Furthermore, the study aims to identify whether attitudes towards halal products play a mediating role in these effects.

Design/methodology/approach

Data were collected from 847 people living in Turkey using an online survey. The authors empirically tested the proposed conceptual model via structural equation modeling.

Findings

The study’s results show that trust in halal products has a positive impact on both the intention to buy halal products and the attitude towards them. Moreover, one’s attitude towards halal products affects the intention to purchase them. Additionally, one’s religiosity-belief level influences the intention to purchase halal products, while religiosity-practice level influences the attitude towards halal products. Furthermore, through indirect effect analyses, it was found that trust in halal products and religious practices has an indirect impact on intention through attitude.

Research limitations/implications

These outcomes significantly contribute to understanding the complex interactions between trust in halal products, levels of religiosity, and attitudes in shaping consumers' purchase intentions and approaches towards halal products. These implications offer valuable insights into how consumers' religious beliefs, trust perceptions, and attitudes influence their purchase of halal-certified products. Validating these conclusions on a larger scale and exploring them in different contexts would be beneficial.

Practical implications

The practice dimension of religiosity pertains to performing actions prescribed by the religion, embodying the practical applications of religious teachings. According to the research findings, the belief dimension of religiosity significantly and positively affects the intention to purchase halal products. This finding aligns with several prior studies.

Social implications

Sharing information on websites, social media platforms, or product packaging can be effective. If businesses genuinely adhere to halal standards and address the genuine needs of consumers who value halal products, they can enhance consumers' interest in such products.

Originality/value

This research was conducted in Turkey, where most people follow the Muslim faith. The main objective of the study was to examine the trust levels of consumers who have strong religious beliefs and are sensitive to consuming halal products. The study looked at trust on three levels: trust in the halal product, trust in the company that produces halal products, and trust in institutions that provide halal certification. The study also looked at the religiosity levels of the consumers using a two-dimensional approach, which included their beliefs and practices.

Abstract

Purpose

The current investigation aims at observing the influence of the cooling channel on the thermal and residual stress behavior of the selective laser melting (SLM)316L uni-layer thermo-mechanical model.

Design/methodology/approach

On a thermo-mechanical model with a cooling channel, the effect of scanning direction, parallel and perpendicular and scan spacing was simulated. The effect of underlying solid and powder bases was evaluated on residual stress profile and thermal variables at various locations.

Findings

The high heat dissipation of solid base due to high cooling rates and steep thermal gradients can reciprocate with smaller melt pool temperature and melt pool size. Given the same scan spacing, residual stresses were found lower when laser scanning was perpendicular to the cooling channel. Moreover, large scan spacing was found to increase residual stresses.

Originality/value

Cooling channels are increasingly being used in additive manufacturing; however, their effect on the residual stress behavior of the SLM component is not extensively studied. This research can serve as a foundation for further inquiries into the impact of base material design such as cooling channels on manufactured components using SLM.

Abstract

Purpose

The purpose of this paper is to evaluate the effect of post process combinations, e.g. hot isostatic pressing (HIP) only, HIP + T6 heat treatments, and T6 only, with different aging time, on surface properties, microstructure and mechanical properties of stress-relieved AlSi10Mg parts produced by direct laser metal sintering.

Design/methodology/approach

HIP process and HIP + T6 heat treatments were applied to as stress-relieved direct laser metal sintered (DMLS) AlSi10Mg parts. Aging times of 4 and 12 h are selected to examine the optimum duration. To analyze the advantages of HIP process, a T6 heat treatment with 4 h of aging was also applied. Densities, open porosities and roughness values of as stress-relieved, HIPed, HIP + T6, and T6-only samples were measured. The samples were characterized by OM and SEM together with EDX analysis. An image analysis study was made to evaluate the inner pore structure, thereby to understand the mechanical behavior.

Findings

HIP process does not cause a significant change in surface porosity; yet it has a positive influence on inner porosity. HIP process results in a microstructure of the aluminum matrix surrounded by a network of micron and nano size Si particles. Additional heat treatment results in larger particles and precipitation. After HIPing, ductility increases but strength decreases. Samples aged 4 h present improved yield and tensile strength but decreased elongation, yet samples aged for 12 h reach a combination of optimum strength and ductility. The lower level of tensile strength and ductility in T6-only condition indicates that HIP process plays a crucial role in elimination of the porosity thus improves the effectiveness of subsequent heat treatment.

Originality/value

The study investigates the effect of post-process conditions and optimizes the aging time of the T6 heat treatment after HIP process in order to obtain improved mechanical properties. The stress-relieved state was chosen as the reference to prevent distortion during HIPing or heat treatment.

Abstract

Purpose

The present study aims to investigate the effect of finish machining and aging processes on the surface integrity of the selective laser melted (SLM) maraging steel samples and compared them with those obtained conventionally.

Design/methodology/approach

Finish machining and aging were applied on the SLM and wrought maraging samples to investigate and compare their microstructural and mechanical properties such as surface roughness, microhardness and wear resistance.

Findings

After applying aging and finish machining treatments, the surface roughness <1 µm, microhardness (542Hv) and wear resistance (COF 0.578) of SLM samples were similar to their wrought counterparts. Compared to finish machining, the effect of aging was more significant on the microhardness and the wear resistance, regardless of sample type.

Originality/value

The knowledge of post-processing is essential to enhance the functional performance of the SLM samples. Aging and finish machining were applied for the first time to evaluate the surface integrity of the SLM prepared maraging steel and compared it with the wrought samples.

Abstract

Purpose

This paper aims to propose a new approach called “analytical hierarchy process weighted fuzzy linear programming model (AHP‐FLP)” for supplier selection.

Design/methodology/approach

A hybrid method of supplier selection, AHP‐FLP is applied to a real industry case. The weights of the various criteria, taken as local weights from a given judgment matrix, are calculated using analytical hierarchy process (AHP) that are also considered as the weights of the fuzzy linear programming model. This new model is compared with the classical AHP method.

Findings

This study concluded that the AHP‐FLP method outperforms the AHP method for supplier selection with respect to restricted supplier selection criteria. Drawing on a real case, Supplier 1 was identified to be the best supplier through the AHP model under no restrictions, which contradicts the finding that Supplier 2 was selected as the best supplier by the AHP‐FLP model subject to constraints.

Research limitations/implications

More research is definitely called for within the context of studying a more complex supply chain with multiple supply network and nodes. There is also a crucial need for investigating other hybrid methods to find the optimum supplier.

Practical implications

The findings of this study indicate that the weights of supplier selection criteria calculated by the AHP‐FLP model are in line with the actual supplier selection decision of purchasing managers. Since the AHP‐FLP model is relatively more difficult to implement compared with the crisp AHP, its application will be more appropriate for high‐value components where stringent purchasing criteria are required. In contrast, AHP remains an appropriate approach for relatively lower value components (C class).

Originality/value

The novelty of this study lies in the application of a hybrid approach to a real industry case. This study has dealt with one of the most important subjects in supply chain management, providing a better decision for supplier selection using appropriate quantitative techniques.

Abstract

Purpose

The purpose of this paper is to explore top government hands-on megaproject management model applied to Istanbul’s new airport megaproject. The study aims to find an answer to this research question: “How is the organizational design and management of a megaproject that has been alive in a confrontational socio-political environment and whose national strategic importance is high?”

Design/methodology/approach

Organizational theory and critical theory perspectives are used in this study. Istanbul’s grand airport is chosen as the case study. Interview, focus group and document analysis methods are used together. The research yields data from qualitative resources. Verbal and written materials are organized into three major themes and 27 key subjects for content analysis.

Findings

A top level of organizational management can be attained in the state in order for the mega projects with high national strategic importance to survive without problems and with high performance. The top government-level organizational structure implemented at Istanbul’s new airport has reduced complexity, risk and uncertainty; increased performance and product quality; and strenghtened inter-organizational compatibility and communication within the megaproject organization. However, this structuring also increased centralization, reduced transparency and direct public participation in the decision-making process.

Research limitations/implications

The megaproject is run in strict confidence and limited information is shared gradually in a controlled way with public by the megaproject organization. Therefore, a qualitative methodology is followed and the usage of quantitative data remained limited in the research.

Practical implications

The study presents an exemplary top government-level megaproject management model for countries experiencing strong socio-political conflicts and aiming to perform megaprojects with high national strategic importance.

Social implications

The organization of Istanbul’s new airport megaproject offers an exemplary, flexible and innovative organizational management model for countries that want to realize mega projects with high national strategic importance and experience strong socio-political conflicts. The questions of how to cope with challenges, how to build management capabilities and how to improve the cooperation and coordination within megaprojects have found some answers with this study. In addition, this study provides an insight into how to make more effective objections to wrong megaproject practices and the right strategies that the opposing organizations can follow.

Originality/value

This empirical research widens and deepens the theoretical foundations of top government hands-on megaproject management. The study, which includes a process analysis, allows to better understand the philosophy, nature, success, planning process, social organization and dynamics of megaprojects and to explain them through the values and strategies of organizations.

Abstract

Purpose

This paper aims to achieve two goals: first, to evaluate the existing interest-free monetary policy tools in the major Islamic financial hubs of Malaysia, Pakistan and Bahrain and; second, to suggest how monetary policy tools in Turkey can be used in other countries.

Design/methodology/approach

This study follows a qualitative research method based on literature review, comparison, evaluation and design.

Findings

The policy rate cannot be used due to Shariah concerns. The reserve requirement depends on qard, and the reserves should be kept separately in the central bank. In terms of ijarah sukuk, Shariah concerns should be taken into account and a new structure, as displayed in Figure 3, should be followed. Government investment certificates can be used as an interest-free monetary policy tool. A genuine mudarabah interbank investments can also be used. Wadiah acceptance with no habitual gift can be used as well, and Tawarruq and central bank notes are not preferable due to Shariah concerns as well. Having said that, a Turkey-based tawarruq platform can be structured for others to use instead of applying to London.

Originality/value

This paper’s unique suggestion is to develop an interbank taqaruz market and a taqaruz method with the central bank. It is also unique for Turkey in the subject.

Abstract

Higher education institutions around the world compete with one another in the internationalization zone. One of the biggest competitions centers on the mobility of students fighting for the share from the student market pie. The Turkish higher education system, as an emerging competitor, also participates in this competition. While many studies focus on international students in Turkish higher education institutions, the literature lacks information about why Turkish institutions participate in this game, and what tools and strategies they use in this endeavor. This study examined the rationales and strategies of higher education institutions using a semistructured online survey data collected from international offices at participating institutions. Findings revealed that Turkish higher education institutions attract international students to create a multicultural environment by increasing diversity at the campus and to increase the quality of the institution. In contrast to the findings in the literature, seeing international students as institutional revenue source was not among the rationales mentioned by the participant institutions. Besides the rationales, findings also revealed the strategies institutions use for their international student recruitment. Paralleling with the trending mechanisms used worldwide, Turkish institutions use similar strategies such as participating in fairs and events, advertisement through technology, web and social media, and using agents; however, there are also unique mechanisms created by Turkish institutions including visiting parents of current international students, high school visits, and summer camps as effective strategies. Additional research, with broader scope and depth is needed to better understand the internationalization of Turkish higher education.

Abstract

Purpose

The purpose of this paper is to explore the effects of personality traits on teachers’ technology acceptance.

Design/methodology/approach

To this end, a demographic information survey, Five-Factor inventory, and technology acceptance measure were used for data collection. The data were analyzed via structural equation modeling.

Findings

According to the findings, conscientiousness has no significant effect on behavioral intention (BI) whereas openness and extraversion have positive indirect effects. On the other hand, agreeableness and neuroticism have negative indirect effects on BI. It was seen that the developed model explains 70 percent of BI, 77 percent of attitude toward use, 42 percent of perceived usefulness, 64 percent of perceived ease of use, and 15 percent of computer self-efficacy (CSE). It was revealed that CSE mediates the indirect effects of different personality traits on these variables.

Practical implications

In this regard, highlighting the conveniences to be brought by using Tablet PCs and equipping teachers with competencies to use relevant technologies during teacher training and in-service training may be effective in developing BI to use Tablet PCs among teachers.

Originality/value

The present study is different from previous studies in that it examines more than one technology through more than one measurement, takes personality as the predictor of technology use tendencies, and focuses on causal relationships between technology use and personality.
