Abstract

Purpose

In 2008, a phenomenon emerged in online retail that attracted the attention of many people, creating a new virtual model of commerce. This phenomenon was called online group buying and arrived in Brazil in 2010. The purpose of this study was to identify the factors that affect satisfaction and loyalty to group buying sites.

Design/methodology/approach

Through structural equation modeling, the relationships between the attractiveness of discount rates, service quality, popularity, online brand image, antecedent word of mouth (WOM), creativity and trust in relation to consumer general satisfaction, declared loyalty, repurchase intention and positive WOM were observed. A total of 727 valid questionnaires were collected from online group buyers to test the 11 hypotheses proposed in this study.

Findings

The main contribution of this study was that it identified the strong influence of service quality, popularity and online brand image on consumer general satisfaction, and the influence of service quality, trust and general satisfaction on repurchase intention. It also identified the influence of trust, creativity and general satisfaction on declared loyalty, and finally, the influence of trust and general satisfaction on positive WOM.

Research limitations/implications

Because of the extensive and robust model, other statistical interactions among the constructs were gauged. It is possible that new structures and paths for alternative models can be proposed in the future with the inclusion of new relationships not analyzed in the present study. Furthermore, future studies should consider testing the generated model in other countries, as the particular features of collective purchasing in Brazil should be taken into account.

Practical implications

In addition to being concerned with the attractiveness of discounts, marketing managers of group buying sites should concentrate their efforts on strengthening perceived quality, image, trust and the creativity of the site to ensure customer loyalty.

Social implications

The online group buying business model that was established in Brazil differs significantly from the American and European models. As many online group buying studies have been conducted in these markets, Brazilian consumers will enjoy substantial gains in the quality of the service provided by collective purchasing sites through the development of actions that focus on improving the factors that affect these consumers.

Originality/value

The originality of this study lies in the development of a single model that tests a set of factors gauged separately in other studies related to online purchase behavior in a broader perspective.

Abstract

Purpose

The purpose of this paper is to establish a Process-aware FMEA (PAFMEA) development environment in order to face the main Failure Mode Effect Analysis (FMEA) deficiencies concerning failure analysis in maintenance.

Design/methodology/approach

The proposed framework integrates Delphi methodology to obtain consensus of specialists’ opinions, analytic hierarchy process (AHP) to perform multiple criteria-based risk assessment and a business process management system to instantiate the development cycle. A conceptual model is presented and analyzed through a case study.

Findings

PAFMEA reveals a new perception in the evaluation and prioritization of failure modes during maintenance failure analysis, such as risk definition and resource availability, dealing with conflicting characteristics in decision-making approaches.

Practical implications

The PAFMEA environment includes requirements that are grouped with a process instantiation of an AHP structure, providing a high degree of applicability and performance to the development cycles of the FMEA. The new method confronts the classical risk assessment approach and contributes to the literature, adding new perspectives to the FMEA analysis.

Originality/value

PAFMEA brings new and promising perspectives to the FMEA development cycle, which, in short, means adding on a multi-criteria failure analysis method (AHP) through a process-aware platform, with performance impacts in FMEA knowledge sharing, decision making and delivery.

Abstract

Purpose

This study aims to describe a bibliometric analysis of recent articles addressing the applications of e- noses with particular emphasis on those dealing with fuel-related products. Documents covering the general area of e-nose research and published between 1975 and 2021 were retrieved from the Web of Science database, and peer-reviewed articles were selected and appraised according to specific descriptors and criteria.

Design/methodology/approach

Analyses were performed by mapping the knowledge domain using the software tools VOSviewer and RStudio. It was possible to identify the countries, research organizations, authors and disciplines that were most prolific in the area, together with the most cited articles and the most frequent keywords. A total of 3,921 articles published in peer-reviewed journals were initially retrieved but only 47 (1.19%) described fuel-related e-nose applications with original articles published in indexed journals. However, this number was reduced to 38 (0.96%) articles strictly related to the target subject.

Findings

Rigorous appraisal of these documents yielded 22 articles that could be classified into two groups, those aimed at predicting the values of key parameters and those dealing with the discrimination of samples. Most of these 22 selected articles (68.2%) were published between 2017 and 2021, but little evidence was apparent of international collaboration between researchers and institutions currently working on this topic. The strategy of switching energy systems away from fossil fuels towards low-carbon renewable technologies that has been adopted by many countries will generate substantial research opportunities in the prediction, discrimination and quantification of volatiles in biofuels using e-nose.

Research limitations/implications

It is important to highlight that the greatest difficulty in using the e-nose is the interpretation of the data generated by the equipment; most studies have so far used the maximum value of the electrical resistance signal of each e-nose sensor as the only data provided by this sensor; however, from 2019 onwards, some works began to consider the entire electrical resistance curve as a data source, extracting more information from it.

Originality/value

This study opens a new and promising way for the effective use of e-nose as a fuel analysis instrument, as low-cost sensors can be developed for use with the new data analysis methodology, enabling the production of portable, cheaper and more reliable equipment.

Abstract

Purpose

The aim of this paper is to explore the possibility of using the Define-Measure-Analyze-Improve-Control (DMAIC) cycle, process mining (PM) and multi-criteria decision methods in an integrated way so that these three elements combined result in a methodology called the Agile DMAIC cycle, which brings more agility and reliability in the execution of the Six Sigma process.

Design/methodology/approach

The approach taken by the authors in this study was to analyze the studies arising from this union of concepts and to focus on using PM tools where appropriate to accelerate the DMAIC cycle by improving the first two steps, and to test using the AHP as a decision-making process, to bring more excellent reliability in the definition of indicators.

Findings

It was indicated that there was a gain with acquiring indicators and process maps generated by PM. And through the AHP, there was a greater accuracy in determining the importance of the indicators.

Practical implications

Through the results and findings of this study, more organizations can understand the potential of integrating Six Sigma and PM. It was just developed for the first two steps of the DMAIC cycle, and it is also a replicable method for any Six Sigma project where data acquisition through mining is possible.

Originality/value

The authors develop a fully applicable and understandable methodology which can be replicated in other settings and expanded in future research.

Abstract

Purpose

The purpose of this article is to investigate the interrelationships between innovation climate and human capital in the development of dynamic capabilities related to innovation. The study presents a set of concepts about variables involved in the innovation process and their interrelationship, addressing the analysis of international scientific production related to the antecedents of the innovation climate, human capital and dynamic capabilities.

Design/methodology/approach

A review of the literature from 1998 to 2018 was carried out, using descriptive statistical methods, at first, and qualitative analysis of the results in order to visualize the current configuration of the field of study of innovation background.

Findings

The results demonstrate a significant number of studies relating human capital and dynamic capabilities and little quantitative significance in studies relating to a climate of innovation and dynamic capabilities. The research describes how the dynamic capabilities of innovation have been approached in a conceptual model based on the perspective of human capital and innovation climate.

Research limitations/implications

The study did not contemplate the analysis of the interrelationship between the resource configuration construct and the dynamic innovation capacities (part of the gap pointed out by Tuzovic, Wirtz and Heracleous (2018), constituting a perceptible limitation of the analyzes carried out in this article.

Practical implications

The influence of the innovation climate construct and its relationship with dynamic innovation capabilities deserves greater attention in research with an empirical approach, constituting a field to be explored by scientific research in organizations.

Originality/value

The research sought to investigate the gap involving the interrelations between innovation climate and human capital in the development of dynamic capabilities related to innovation, indicating the need for further empirical studies on the subject.

Abstract

Purpose

Drum-Buffer-Rope (DBR) is a method to adjust production flows, synchronize the release of materials and enable a process of focused improvement in production systems. Literature on DBR applications in engineer-to-order (ETO) production systems, where customers participate in product design decisions and, consequently, in the way production is planned and executed, is rare. However, the interest in improving production management in ETO systems has received attention from the scientific and business communities. The goal of this research was to evaluate the implementation of DBR in an ETO productive system, critically analyzing the necessary adaptations for its use.

Design/methodology/approach

This research was conducted through a case study in a company that manufactures electronic equipment, known as avionics, in the aerospace sector.

Findings

In this context, the contribution of this study consists of evaluation of the implementation of DBR in an ETO productive system, describing the implementation and the necessary adaptations of the DBR to the ETO productive system explored, comparing it with the DBR theoretical proposals and Simplified Drum-Buffer-Rope (S-DBR) methods.

Originality/value

The study contributes to knowledge by expanding the field of the DBR application to make it more precise, and by applying the theory of constraints, in a general manner, to this type of productive environment.

Abstract

Purpose

After a hiatus in the research on individual differences in negotiation, there has been a surge of renewed interest in recent years followed by several new findings. The purpose of this paper is to explore the effects that personality, as structured by the five-factor model, have over negotiation behavior and decision making in order to create new knowledge and prescribe advice to negotiators.

Design/methodology/approach

This study replicates observations from earlier studies but with the innovation of using a different methodology, as data from a sample of volunteer participants were collected in regard to their personality and behavior during two computerized negotiation simulations, one with the potential for joint gains and the other following a more traditional bargaining scenario.

Findings

Significant results for both settings were found, with the personality dimensions of agreeableness, conscientiousness, and extraversion systematically reoccurring as the most statistically relevant, although expressing different roles according to the type of negotiation and measure being registered. The findings thus suggest a multidimensional relationship between personality and situational variables in which specific traits can either become liabilities or assets depending upon whether the potential for value creation is present or not.

Originality/value

The new findings on the impacts of personality traits on both distributive and integrative negotiations allow negotiators to improve their performance and to adapt to specific distributive or integrative negotiation situations.

Abstract

Purpose

The purpose of this paper is to measure Mexicans’ perceptions and attitudes about the production and consumption of genetically modified organisms (GMOs).

Design/methodology/approach

A questionnaire with 63 questions that encompassed 11 latent factors was used to obtain information. The questionnaire was administered to 14,720 people in Mexico’s urban areas.

Findings

The results revealed important similarities and differences with studies in other countries, showing mainly that the respondents did not have sufficient information about GMOs, they have low level of knowledge about GMOs (31.28 percent), are highly distrustful of GMOs, perceive high risk regarding GMOs (59.13 percent), want transgenic products to be labeled (93.59 percent) and do not perceive GMOs’ social values and positive health effects beyond increasing agricultural productivity. Also, it was observed that the higher the educational level of individuals, the lower the acceptance of GMOs.

Research limitations/implications

The authors conclude that it is necessary to generate and provide scientifically accurate information on GMOs, so that people are better informed and can give a critical opinion on the use of GMOs.

Practical implications

The major practical contribution of this research is that it provides empirical knowledge about the perceptions and attitudes toward the production and consumption of GMOs among the Mexican’s urban society, which can be of great help for the Mexican government to rethink if it is an appropriate moment to completely open the doors to international companies to cultivate crops like maize and others that have been postponed due to pressure from the environmental groups, farmers and other sectors of the society.

Social implications

This is especially important in the context of maize as it is part of the cultural heritage of Mexico since ancient times. However, it is not clear what the overall perception is in the Mexican society on the use of GMOs for cultivation.

Originality/value

Southern regions of Mexico are the center of origin of several cultivated plants such as maize and legumes. The introduction of GMOs, called transgenics, in agriculture and food continues to cause enormous controversy in the perceptions and attitudes mainly among environmental groups and farmers in Mexico.
