Abstract
Purpose
The purpose of this paper is to predict the yield locus of porous ductile materials, evaluate the impact of void geometry and compare the computational results with existing analytical models.
Design/methodology/approach
A computational homogenization strategy for the definition of the elasto-plastic transition is proposed. Representative volume elements (RVEs) containing single-centred ellipsoidal voids are analysed using three-dimensional finite element models under the geometrically non-linear hypothesis of finite strains. Yield curves are obtained by means of systematic analysis of RVEs considering different kinematical models: linear boundary displacements (upper bound), boundary displacement fluctuation periodicity and uniform boundary traction (lower bound).
Findings
The influence of void geometry is captured and the reduction in the material strength is observed. Analytical models usually overestimate the impact of void geometry on the yield locus.
Originality/value
This paper proposes an alternative criterion for porous ductile materials and assesses the accuracy of analytical models through the simulation of three-dimensional finite element models under geometrically non-linear hypothesis.

Abstract
We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

This paper aims to analyze the degree of contribution of the entrepreneurial orientation (EO) of organizations in the use of agile methods (AM) in project management.
Abstract
Purpose
This paper aims to analyze the degree of contribution of the entrepreneurial orientation (EO) of organizations in the use of agile methods (AM) in project management.
Design/methodology/approach
A quantitative approach with the application of a survey with project professionals resulted in 206 valid answers. The data were analyzed using structural equation modeling and the method of partial least squares (PLS).
Findings
The results present empirical evidence of the significant contribution of EO in the use of AM in project management, confirming the main hypothesis of this study. This effect was not influenced by the control variables tested.
Research limitations/implications
This study contributes to the development of research on AM and minimizes the literature gap on the connection between entrepreneurship and AM. The results are limited to the sample. Studies with broader samples and different segments are suggested, as well as the contribution of each dimension of the EO to AM.
Practical implications
Innovativeness, risk-taking, proactiveness, autonomy and competitive aggressiveness (EO dimensions) can contribute to the use of AM and guide actions to develop these behaviors, pursuing better adherence to agile values and the use of AM in project management.
Originality/value
The originality of this study regarding the connection between EO and AM lies on the presentation of a theoretical model of this relationship and reduces the gap in this research field. Given the degree of EO contribution in AM (19.7%), there are other factors that affect the use of AM in project management that should be investigated.

Abstract
Purpose
Despite the growing competition between higher education institutions and the empirical evidence that the brand is a relevant determinant of consumer preference, research studies on negative consumer–brand relationships (CBRs) are still scarce. Thus, this research intends to fill this gap, determining the antecedents of brand hate in educational institutions and identifying gender differences regarding the determinants of brand hate.
Design/methodology/approach
A survey was carried out with 450 current students from higher education institutions. The proposed model was tested using partial least squares structural equation modeling (PLS-SEM) in SmartPLS3.
Findings
According to the results, previous negative experiences are the most significant driver of brand hate, with higher emphasis on male students. In this sense, investment in customer experience management (CXM) consists of a relevant strategy for higher education institutions. It was also observed that female students develop hate for ideological incongruity (ethical/moral behavior) and symbolic incongruence (lack of brand identity), revealing unprecedented facets of the phenomenon.
Originality/value
This research extends the studies’ negative CBRs to educational institutions. It explores gender differences related to brand hate; a topic not explored before, but that enables a targeted approach of brand strategies. Finally, it provides managerial implications allowing the strategy to reduce negative CBRs and their consequences in educational institutions.

Abstract
Purpose
This paper aims to conceptualize impacts of higher education institutions (HEIs) on sustainable development (SD), complementing previous literature reviews by broadening the perspective from what HEIs do in pursuit of SD to how these activities impact society, the environment and the economy.
Design/methodology/approach
The paper provides a systematic literature review of peer-reviewed journal articles published between 2005 and 2017. Inductive content analysis was applied to identify major themes and impact areas addressed in the literature to develop a conceptual framework detailing the relationship between HEIs’ activities and their impacts on SD.
Findings
The paper identifies six impact areas where direct and indirect impacts of HEIs on SD may occur. The findings indicate a strong focus on case studies dealing with specific projects and a lack of studies analyzing impacts from a more holistic perspective.
Practical implications
This systematic literature review enables decision-makers in HEIs, researchers and educators to better understand how their activities may affect society, the environment and the economy, and it provides a solid foundation to tackle these impacts.
Social implications
The review highlights that HEIs have an inherent responsibility to make societies more sustainable. HEIs must embed SD into their systems while considering their impacts on society.
Originality/value
This paper provides a holistic conceptualization of HEIs’ impacts on SD. The conceptual framework can be useful for future research that attempts to analyze HEIs’ impacts on SD from a holistic perspective.

Abstract
Purpose
The aim of this paper is to determine chemical and sensory differences of between craft and industrial/or commercial beers. Beer market is nowadays booming and consumers are in the search of new and healthier products.
Design/smethodology/approach
Here, commercial and craft beers were chemically analyzed and sensory evaluated. Chemical analysis included pH, bitterness, color, total polyphenol content and antioxidant activity. Likewise, 40 sensory descriptors were evaluated by trained panelists, including visual, olfactory and gustatory attributes. In addition, an electronic nose (e-nose) was tested to determine its suitability to discriminate beer type and/or style according to their volatiles profile.
Findings
Craft beers presented higher values of color, bitterness and antioxidant activity when compared to commercial beers. Sensory descriptors showed craft beers to be associated with the highest scores in visual, olfactory and gustatory descriptors. Data from e-nose explained 97% of the total variability of the volatile compounds in the analyzed beers, indicating the suitability of this device to discriminate beer types.
Originality/value
Results are of interest for design of marketing and selling techniques for craft brewery managers. In addition, cheap and easy-managing device as e-nose resulted in a valuable tool to monitoring beer quality.

Abstract
Purpose
The digital revolution has brought many challenges and opportunities for the manufacturing firms. The impact of Industry 4.0 technology adoption on sustainable manufacturing and circular economy has been under-researched. This paper aims to review the latest articles in the area of Industry 4.0, sustainable manufacturing and circular economy and further developed a research framework showing key paths.
Design/methodology/approach
Qualitative research is performed in two stages. In the first stage, a review of the extant literature is performed to identify the barriers, drivers, challenges and opportunities. In the second stage, a research framework is proposed to integrate Industry 4.0 technology (big data analytics powered artificial intelligence) adoption, sustainable manufacturing and circular economy capabilities.
Findings
This research extends the knowledge base by providing a detailed review of Industry 4.0, sustainable manufacturing, and circular economy and proposes a research framework by integrating these three contemporary concepts in the context of supply chain management. Through an exploration of this integrative research framework, the authors propose a future research agenda and seven research propositions.
Research limitations/implications
It is important to understand the interplay between institutional pressures, tangible resources and human skills for Industry 4.0 technology (big data analytics powered artificial intelligence) adoption. Industry 4.0 technology (big data analytics powered artificial intelligence) adoption can positively influence sustainable manufacturing and circular economy capabilities. Managers must also put more attention to sustainable manufacturing to develop circular economic capabilities.
Social implications
Factory workers and the local communities generally suffer from various adverse effects resulting from the traditional manufacturing process. The quality of the environment is deteriorating to such an extent that people even staying miles away from the factory are also affected due to environmental pollution that is generated from factory operations. Hence, sustainable manufacturing is the only choice left to manufacturers that can help in the transition to a circular economy. The research framework can help firms to enhance circular economy capabilities.
Originality/value
This review paper contains the most updated work on Industry 4.0, sustainable manufacturing and circular economy. It also proposes a research framework to integrate these three concepts.

Abstract
Purpose
As internet banking service marketing platforms continue to advance, customers exhibit distinct behaviors. Given the extensive array of options and minimal barriers to switching to competitors, the concept of customer churn behavior has emerged as a subject of considerable debate. This study aims to delineate the scope of feature optimization methods for elucidating customer churn behavior within the context of internet banking service marketing. To achieve this goal, the author aims to predict the attrition and migration of customers who use internet banking services using tree-based classifiers.
Design/methodology/approach
The author used various feature optimization methods in tree-based classifiers to predict customer churn behavior using transaction data from customers who use internet banking services. First, the authors conducted feature reduction to eliminate ineffective features and project the data set onto a lower-dimensional space. Next, the author used Recursive Feature Elimination with Cross-Validation (RFECV) to extract the most practical features. Then, the author applied feature importance to assign a score to each input feature. Following this, the author selected C5.0 Decision Tree, Random Forest, XGBoost, AdaBoost, CatBoost and LightGBM as the six tree-based classifier structures.
Findings
This study acclaimed that transaction data is a reliable resource for elucidating customer churn behavior within the context of internet banking service marketing. Experimental findings highlight the operational benefits and enhanced customer retention afforded by implementing feature optimization and leveraging a variety of tree-based classifiers. The results indicate the significance of feature reduction, feature selection and feature importance as the three feature optimization methods in comprehending customer churn prediction. This study demonstrated that feature optimization can improve this prediction by increasing the accuracy and precision of tree-based classifiers and decreasing their error rates.
Originality/value
This research aims to enhance the understanding of customer behavior on internet banking service platforms by predicting churn intentions. This study demonstrates how feature optimization methods influence customer churn prediction performance. This approach included feature reduction, feature selection and assessing feature importance to optimize transaction data analysis. Additionally, the author performed feature optimization within tree-based classifiers to improve performance. The novelty of this approach lies in combining feature optimization methods with tree-based classifiers to effectively capture and articulate customer churn experience in internet banking service marketing.

Abstract
Purpose
This study aimed to identify, with producers of specialty beers (SBs), producers' perceptions regarding the consumers, besides analyzing the consumer's behavior of SBs regarding consumers' preferences, perceptions and determining buying factors.
Design/methodology/approach
In the qualitative analysis, interviews were performed with 14 professionals from the SB industry. In the quantitative study, 301 consumers of SB answered a questionnaire about preferences, perception and determining buying factors of special beer. Techniques such as content analysis, frequency analysis, cross-tabulation and hierarchical cluster analysis were used in this study.
Findings
The study demonstrated an important convergence in the perceptions of producers about consumers and the real behavior of SB consumers, mainly on factors of beer packaging, label, style and price. Those respondents consuming just SB were characterized by having higher income, frequency and time of beer consumption and willingness to pay more for the product. Cluster analysis allowed to segment respondents into three groups: (1) beginners in the universe of SBs who also drink commercial beers; (2) regular consumers willing to pay more for SB and (3) legitimate consumers of SB averse to commercial beer.
Practical implications
There are practical implications in this study such as new products development and assertive creation of labels and packaging for special beers.
Social implications
There are social implications in this study such as the convergence between industry professionals and consumers.
Originality/value
By addressing professionals and consumers, this study generated scientific information and knowledge to assist the specialty brewing industry in developing new products and defining marketing strategies as well as creating actions for bringing producers and consumers closer together to benefit both parties.
