Abstract
Purpose
The purpose of this paper is to characterize the interfaces between manufacturing companies and the Internet of Things (IoT) suppliers involved in their digital servitization.
Design/methodology/approach
This paper builds on an explorative case study of a manufacturing firm and its IoT suppliers. This paper relies on the Industrial Network Approach to study interfaces between buying firms and their suppliers.
Findings
This paper identifies three distinct types of supplier interfaces: connected, digital and digital-physical. They all contain technical resource interfaces with additional organizational and/or technical complexities that need to be managed. Connectivity, an Agile approach to software development and strong technical dependence emerged as key factors that impact the interactions between manufacturing firms and IoT suppliers and how their resources are combined.
Practical implications
This paper offers managerial implications regarding the importance of internal organization (such as appropriate cross-functional teams) to manage the dynamics of collaborations required by digital technologies, maintain interactions with IoT suppliers and identify and manage interdependences between IoT suppliers. Building close relationships with suppliers of crucial infrastructure (e.g. IoT cloud platform and data security systems) can also be beneficial for manufacturing firms to reduce risks. Finally, attention should be given to IoT technology strategy, which impacts both digital and digital-physical supplier interfaces.
Originality/value
In digital servitization, manufacturing firms are heavily reliant on external resources for IoT technology. Despite this, few studies have investigated the characteristics of their interfaces with IoT suppliers, how these can be managed and how resources are combined.

The purpose of this paper is to analyze the existence and influence of gender effects on wine choice, specifically whether women and men seek the same cues in wine labelling.
Abstract
Purpose
The purpose of this paper is to analyze the existence and influence of gender effects on wine choice, specifically whether women and men seek the same cues in wine labelling.
Design/methodology/approach
Five focus groups, involving 45 regular wine consumers (22 women and 23 men) from four Portuguese wine regions of origin, were conducted. Sessions included two projective techniques. To gather more information, participants were asked to fill a short questionnaire, relating purchasing and consumption habits, knowledge and socioeconomic characteristics. Qualitative data were transcribed verbatim and content analysis was used.
Findings
Women frequently associate wine to the context of consumption; while men frequently associate wine to convivial and sensorial pleasure. Region of origin and prior knowledge experience seem to be the two main reasons for men to choose a wine; while, women seem to rely more on wine brand and previous experience. Front label information (region of origin, awards and region illustration) seems to be more important for women, while the back label descriptors (grape variety, world heritage site and wine history) are more relevant for men. The typography (font size) and information type were identified as negative aspects of the back label.
Practical implications
Understanding how men and women looking for information on a wine bottle can help marketers communicate with specific market segments. This paper provides insights to design marketing campaigns regarding product customization at the level of label information and design.
Originality/value
The present research contributes to current literature on wine consumer behaviour, exploring behavioural differences, perceptions and motivations by gender. In particular, the relevance of wine cues for choice decision is explored. The evidence of focus groups combined with projective techniques is complemented with data collected through a questionnaire.

Abstract
Purpose
This paper aims to investigate the relationship between creativity, entrepreneurial intention and social innovation tendency within academic community members (namely, students and professors/researchers).
Design/methodology/approach
A questionnaire was administered to nearly 300 students and professors/researchers in Portuguese higher education institutions, whereupon a mediation analysis was performed to understand the aforementioned relationship.
Findings
The results indicate a positive relationship between individual creativity, entrepreneurial intention and social innovation tendency and that entrepreneurial intention mediates the relationship between creativity and social innovation tendency.
Research limitations/implications
Firstly, the results obtained to fit the specific characteristics of the sample used, suggesting that it would be risky to extrapolate to other contexts. Secondly, although the constructs used to measure variable creativity are based on the extant literature, these may be open to debate and possibly, therefore, alternative measures could have been used.
Practical implications
The findings of the paper have important practical implications within the university context, namely: that study programmes should be designed to address the entrepreneurial potential of their students, teaching and research staff; that social entrepreneurship, volunteering activities and the development of creativity skills should be stimulated; and, finally, that social innovation should be at the core of a university’s mission.
Originality/value
To the authors’ best knowledge, this is the first time that the relationship between creativity, entrepreneurial intention and social innovation tendency has been empirically tested. To do this, a conceptual framework is proposed which suggests that individual creativity can be perceived by means of three interconnected constructs (the self, family and university creativity), which, in turn, predict entrepreneurial intention and social innovation tendency.

Abstract
Purpose
This paper aims to define a proposal of a theoretical–methodological framework aimed at supporting researchers in conducting studies on the topic of environmental mobility.
Design/methodology/approach
The complexity of environmental change and the frequent subsequent human mobility raises challenges in the research process. The variety of theoretical and methodological approaches that can be applied to each of the phenomena contributes to different layers of analysis when focusing on the decision-making process of migration due to environmental factors. Drawing from the theoretical and methodological frameworks used by scholars, this paper includes an analysis of how they are applied in empirical studies that focus on environmental change and mobility in the Middle East and North Africa (MENA) region.
Findings
Empirical studies in this field for the MENA region are focused on collecting and analyzing data but are not linking it with wider human mobility theoretical and methodological frameworks. The proposal included in this study privileges the use of a qualitative methodology, aimed at obtaining an overview of the individuals’ experience.
Originality/value
This study adds to existing overviews of empirical studies of environmentally induced mobility by analyzing in detail the dimensions used to frame the methodological and theoretical research approaches in the empirical studies used in different disciplines that study the environment and/or human mobility. The studies analyzed focus on the different countries in the MENA region, which has the highest level of forced migratory movements in the world while facing challenges in terms of environmental degradation.

Abstract
Purpose
The purpose of this paper is to review recent advances and current issues in the realm of sequentially linear analysis.
Design/methodology/approach
Sequentially linear analysis is an alternative to non‐linear finite element analysis of structures when bifurcation, snap‐back or divergence problems arise. The incremental‐iterative procedure, adopted in nonlinear finite element analysis, is replaced by a sequence of scaled linear finite element analyses with decreasing secant stiffness, corresponding to local damage increments. The focus is on reinforced concrete structures, where multiple cracks initiate and compete to survive.
Findings
Compared to nonlinear smeared crack models in incremental‐iterative settings, the sequentially linear model is shown to be robust and effective in predicting localizations, crack spacing and crack width as well as brittle shear behavior. To date, sequentially linear analysis has not been devised with a proper crack closing algorithm. Besides, of utmost importance for many practical applications, sequentially linear analysis requires an improvement of the algorithm to deal with non‐proportional loadings.
Originality/value
This article gives an up‐to‐date research overview on the applicability of sequentially linear analysis. For the issue of non‐proportional loading, it indicates solution directions.

Abstract
Purpose
In the carbon dioxide capture and storage (CCS) project, the integrity of CO2 injection wells plays a vital role in the long‐term safety of CO2 storage. The authors aim to practically investigate possible CO2 leakage of a CO2 injection well section during the injection operation and shut‐in by the thermomechanical FEM simulation. The application of numerical simulation to the CO2 injection well deep underground is the first step that will help in the quantitative evaluation of the mechanical risks.
Design/methodology/approach
The injection of CO2 at a temperature different from those of the well and the surrounding geological formation is likely to cause different thermal deformations of constitutive well materials. This could lead to cement cracking and microannuli openings at the interfaces of different materials such as casing/cement and cement/rock. In this paper, the possibility and order of magnitude of cement cracking and microannuli creation in the cross section of the well are assessed from a numerical case study within a classical thermomechanical finite element model framework.
Findings
The possibility of compressive failure and tensile cracking in the cement of the studied wells due to CO2 injection is small unless a large casing eccentricity or an initial defect in the cement is present. Some microannuli openings are generated at interfaces cement/casing and/or cement/rock during the CO2 injection because of different thermal shrinkage of each material. However, the width is not important enough to cause significant CO2 leakage under the studied conditions. The use of “flexible” cement especially developed for oil well applications could mitigate the risk of cement cracking during CO2 injection.
Originality/value
Numerous experimental studies on the chemical deterioration of the cement under severe conditions have been carried out. On the other hand, only a few investigations have focused on the mechanical behavior under thermal/pressure changes related to CO2 injection. In this paper, the quantitative analysis to investigate cement cracking and microannuli formation is achieved to help in the identification of possible mechanical defects to cause CO2 leakage. In addition, the discussion about the risk of the possible casing eccentricity and the application of flexible cement in the oil and gas field to CO2 injection well could be practically useful.

Abstract
Purpose
The paper aims to present an experimental testing program regarding reinforced concrete slabs, with and without shear reinforcement, submitted to punching under both symmetric and eccentric loading. Comparisons between numerical simulations and experimental behaviour results are carried on. The capabilities and limitations of the numerical model to reproduce the brittle punching‐shear failure are discussed.
Design/methodology/approach
The paper opted for a performance assessment of a numerical model, comparing FEM results with known experimental tests properly instrumented. Capability of DIANA software to simulate the punching behaviour of slabs is discussed.
Findings
The paper demonstrates that the mechanical properties assigned to the element layer containing the bending reinforcement impose the load deflection stiffness behaviour. Good agreement was found between the predicted and the observed deformation behaviour. Nevertheless, the reproduction of the punching ultimate capacity is strongly dependent on the adopted value for the shear retention factor, which appears to be the major decisive parameter.
Originality/value
This paper demonstrates that the smeared crack model based on both the concept of strain decomposition (SD) and total strain with fixed orthogonal cracks approach (TSF) can correctly be used for the analysis of the behaviour of slabs submitted to punching shear.

Abstract
Purpose
To solve the reinforcement congestion, mechanical anchorage is increasingly popular in use instead of conventional hook rebar. However, the bond performance between the rebar and concrete and the range of stress transfer between the two are still not well understood. The purpose of this study is to study the bond performance and failure mechanisms between reinforcement and concrete around an anchorage zone in a structural element.
Design/methodology/approach
In this study, simulations were carried out by 3D RBSM (Rigid Body Spring Model). This approach divided a problem of interest into elements, namely concrete and steel elements. And to simulate the failure of anchorage of RC, the steel element size is set according to the geometry complexity of the reinforcing bar. By using this method, two simulation cases of anchorage failure were carried out.
Findings
This paper shows that simulations demonstrated good agreement with experimental data in terms of anchorage capacity, crack pattern, and failure mode. This indicates that RBSM analysis can simulate the failure behavior governed by complex cracks.
Originality/value
This paper indicates the analytical approach to investigate the anchorage performance of RC.
