Abstract

Purpose

A wide number of applications requires classifying or grouping data into a set of categories or clusters. The most popular clustering techniques to achieve this objective are K‐means clustering and hierarchical clustering. However, both of these methods necessitate the a priori setting of the cluster number. The purpose of this paper is to present a clustering method based on the use of a niching genetic algorithm to overcome this problem.

Design/methodology/approach

The proposed approach aims at finding the best compromise between the inter‐cluster distance maximization and the intra‐cluster distance minimization through the silhouette index optimization. It is capable of investigating in parallel multiple cluster configurations without requiring any assumption about the cluster number.

Findings

The effectiveness of the proposed approach is demonstrated on 2D benchmarks with non‐overlapping and overlapping clusters.

Originality/value

The proposed approach is also applied to the clustering analysis of railway driving profiles in the context of hybrid supply design. Such a method can help designers to identify different system configurations in compliance with the corresponding clusters: it may guide suppliers towards “market segmentation”, not only fulfilling economic constraints but also technical design objectives.

Abstract

Purpose

The aim of this study is to develop a knowledge scale for nutrients of tropical and traditional fruits for university students and conduct its validity and reliability. Another purpose of the study is to determine whether or not the students' knowledge mean scores about nutrients of tropical and traditional fruits vary based on their demographic information.

Design/methodology/approach

The design of the study was the survey model. While the population consisted of 1,551 students studying in the faculty of health sciences, Gazi University, the sample consisted of 668 students who were determined based on criterion sampling.

Findings

When examining in terms of gender of the students, it was determined that even though mean score of the knowledge scale for nutritional values of tropical and traditional fruits was slightly higher in female students (X¯ = 8.12) than male students (X¯ = 7.71), there was an insignificant difference between them (t(666) = 1.25, p > 0.05). A significant difference was determined between the students' knowledge mean scores of the knowledge scale for nutritional values of tropical and traditional fruits in terms of residence place (t(666) = 2.86, p < 0.5). While the nutritional value mean score of the students residing in Ankara was low (X¯ = 7.67), the nutritional value mean score of the students residing out of Ankara was high (X¯ = 8.58).

Originality/value

When the scale developed in this study is analysed according to demographic information, it can be asserted that the students had knowledge about the nutrients of tropical and traditional fruits. Although tropical fruits are expensive, they still prefer these fruits. It can be stated that the students had knowledge about the diversity, nutritional compounds and antioxidant content of tropical and traditional fruits.

Abstract

Purpose

The purpose of this paper is to present the mechanism of online customer brand trust building through the lens of Walther’s Computer Mediated Communication (CMC) – Social Information Processing Theory (SIPT).

Design/methodology/approach

This paper integrates a range of theoretical and empirical works across branding and marketing, including concept of brand trust, use of online social media in brand communication and customer brand relations and CMC-SIPT theory and relational marketing literature other relevant information which were found useful in the given context were reviewed. The aim was to collect a broad spectrum of ideas, based on their relevance to the research purpose to propose effective online brand trust building framework.

Findings

This paper proposes three different developmental stages in brand trust building on online social media networks. Each stage is guided by the components of CMC-SIPT. Stage I is interaction and compliance of the brand communication clues which suggest that the aggregated level of interaction and compliance in online brand communication on social media determine the movement of the customer to the next level. Stage II suggests information processing at three successive layers by the customer as identification, internalization brand information and bonding, which eventually prompt the customer to the next level of brand trust building. Stage III is related to trust building which is the critical stage as customer internal states of arousal are experienced, which reduces the emotional risk of decision-making and increases confidence and trust of the customers in brands.

Research limitations/implications

The proposed framework of brand trust building has not been tested empirically. Future research could test and validate the proposed model tracking intrinsic changes in the customer in different brand trust development stages. This research is important for marketers or brands who wish to move beyond the notion of merely satisfying customers, to establishing more powerful emotional bonds between their brands and customers. It fills a gap in brand-trust literature and provides marketers and researchers a means to understand and draw strategies for consumers’ attraction toward brands (Patwardhan and Balasubramanian, 2011). The proposed framework has the capacity to revolutionize the way business and brands engage with society by enhancing and establishing trusting relationship.

Originality/value

To date, this research has not been done specifically from the SIPT perspective. This research is the first to examine brand communication strategies in an effort of building brand trust in the context of online social media network from the CMC-Social information theory perspective. It highlights the peculiarities of online brand communication on social media networks and customer information processing in presenting three stages of customer brand trust development to explain the development and flow of events.

Abstract

Purpose

The aim of the present paper was to investigate the inhibition performance of the OF and/or IM on L360 steel in CO2/H2S environments. The pipeline steel surface usually has been pre-treated before using in the oil/gas field, such as by passivation, blackening, and phosphiding. The effectiveness of inhibition can vary because there are many differences between the metal matrix and the treated film.

Design/methodology/approach

Imidazoline (IM) was synthesized by using oleic acid and diethylenetriamine, and its composition was verified using Fourier transform infrared spectroscopy. The oxide film (OF) covering a sample of L360 steel was characterized using X-ray diffraction, and its surface morphology was observed using scanning electron microscope. Electrochemical impedance spectroscopy measurements were conducted to study the inhibition performance of IM- and/or OF-covered L360 steel in the CO2/H2S environments.

Findings

The results show that IM and OF can prevent corrosion on L360 steel in CO2/H2S environments, and the synergistic inhibition effect of IM and OF was very evident. A possible model is proposed to explain the synergistic inhibition effect in the CO2/H2S environments of IM and OF on L360 steel.

Originality/value

Few reports have concerned the effect of the OF on the inhibitor’s performance, especially in CO2/H2S systems. The aim of the present study was to investigate the inhibition performance of the OF and/or IM on L360 steel in CO2/H2S environments. A model is proposed to explain the synergistic inhibition effect mechanism between IM and OF.

Abstract

Purpose

Corrosion inhibitors for copper immersed in emulsion were investigated by experiments and theoretical calculations, and this study aims to propose a new inhibition mechanism of the inhibitors having protective effects for copper corrosion.

Design/methodology/approach

Adsorption behavior of penta-heterocycles (thiophene, 1,2,5-oxadiazole, furan, 2 H-1,2,3-triazole, pyrrole and 1,2,5-thiadiazole) as corrosion inhibitors for copper immersed in oil-in-water (O/W) emulsions was investigated by weight loss, electrochemical tests, morphological characterization and theoretical calculations.

Findings

The orders of inhibition effect are furan < pyrrole < thiophene < 1,2,5-oxadiazole < 2H-1,2,3-triazole < 1,2,5-thiadiazole, and 1,2,5-thiadiazole at 0.5 mM has the best inhibition effect for copper immersed in emulsion. The results of scanning probe microscope, scanning electron microscope and electrochemical test show that a protective barrier can be formed on the surface of copper substrate with six corrosion inhibitors, thus effectively inhibiting the corrosion of copper mainly through chemisorption and following Langmuir’s adsorption isotherm.

Originality/value

Quantum chemical and molecular dynamic simulations demonstrate that all these compounds attached to Cu matrix with a flat-adsorption mode to prevent the emulsion corrode copper. Adsorbed inhibitors act as a barrier at Cu matrix to block corrosion and improve hydrophobicity.

Abstract

Purpose

The purpose of this paper is to explore mechanisms of cultural distance in the base of Chinese Service Multi-National Enterprise (MNE) settings. When attempting to enter overseas markets, many service MNEs face challenges caused by the cultural distance between the home and host countries. Culture distance attracts much attention in academia and industry. However, there are few empirical works to examine how cultural distance affects customer orientation strategies in a global supply chain. This paper aims to answer the following research question: How is the effect of cultural distance on customer acquisition and customer retention strategies, and the effect of customer orientation strategies on the performance of service-oriented MNEs controlled by Chinese capital along the Belt and Road Initiative?

Design/methodology/approach

This paper examines the effect of cultural distance on the customer acquisition strategy and customer retention strategy, and the effect of customer orientation strategies on the performance of Chinese Service MNEs. A large-scale empirical study of Chinese Service MNEs operating in overseas markets is performed and questionnaires were distributed and collected. This paper uses Hofstede's method (Hofstede, 2010), Schwartz's method (Schwartz, 2003) and House et al.'s method (House et al., 2004) to calculate cultural distance. By using each kind of method, this study calculates the absolute culture distance and relative culture distance respectively.

Findings

The results suggest that cultural distance negatively affects customer orientation strategy, customer acquisition strategy positively affects performance and the interaction of customer acquisition and customer retention positively affects performance.

Research limitations/implications

This study aims to contribute to the existing literature with a more fine-grained understanding of the inclusion of customer orientation strategy of Chinese Service MNEs in global supply chains.

Practical implications

The findings outline several important implications that Chinese Service MNEs seeking to expand to overseas markets.

Originality/value

This paper contributes a novel, combined perspective of culture distance and customer orientation strategy.

Abstract

Purpose

Women entrepreneurs contribute significantly to Asian economies. However, women in this region face an alarming array of barriers to entrepreneurship. This research study aims to examine the factors, i.e. government support, family social support, financial literacy and managerial skills, in building the entrepreneurial capacity of women entrepreneurs under the lens of the person–environment (P-E) fit theory. Furthermore, the study also examines the moderating effect of socio-cultural barriers in the said relationships.

Design/methodology/approach

For the study, the data was collected from the owners of 311 women-owned manufacturing and services sector enterprises from the northern Indian community.

Findings

Findings suggest that all the factors significantly affect the entrepreneurial capacity of women entrepreneurs, and the barriers work as a moderator between the relationships.

Originality/value

Based on P-E fit theory, this unique research study proposes a model to test the role of factors such as government support, family social support, financial literacy and managerial skills in developing women entrepreneurs’ entrepreneurial capacity along with examining the moderating role of socio-cultural factors contributing to the entrepreneurial capacity of women.
