This study aims to reduce carbon emissions and costs in an automobile production plant by improving the operational management efficiency of a serial assembly line assisted by a feeding electric tow vehicle (ETV).

A multi-objective function is formulated to minimize the energy consumption of the ETV from which emissions and costs are measured. First, a mixed-integer linear programming model is used to solve the feeding problem for different sizes of the assembly line. Second, a bi-objective optimization (HBOO) model is used to simultaneously minimize the most eco-efficient objectives: the number of completed runs (tours) by the ETV along the assembly line, and the number of visits (stops) made by the ETV to deliver kits of components to workstations.

The most eco-efficient strategy is always the bi-objective optimal solution regardless of the size of the assembly line, whereas, for single objectives, the optimization strategy differs depending on the size of the assembly line.

Instances of the problem are randomly generated to reproduce real conditions of a particular automotive factory according to a previous case study. The optimization procedure allows managers to assess real scenarios improving the assembly line eco-efficiency. These results promote the implementation of automated control of feeding processes in green manufacturing.

The HBOO-model assesses the assembly line performance with a view to reducing the environmental impact effectively and contributes to reducing the existent gap in the literature. The optimization results define key strategies for manufacturing industries eager to integrate battery-operated motors or to address inefficient traffic of automated transport to curb the carbon footprint.

This research aims at analyzing the antecedents of absorptive capacity (ACAP) in the companies incubated in the State of Rio Grande do Norte, Brazil. In this context, 111 incubated companies took part in the research.

The methodology used the confirmatory factor analysis and the multiple linear regression to analyze the relationship of the dependent variables (ACAP) with the dependent variables (interaction with other companies, professionals' knowledge (PK), knowledge use (KU) and knowledge acquisition).

The results highlight that external KU was the construct that most influences the ACAP. Among the dependent variables suggested, only the construct concerning the incubators' PK presented no model significance, which shows that the PK is not an antecedent of ACAP in the incubated companies.

This study is relevant due to pointing out that the incubators may not be providing their professionals with knowledge properly, or that this knowledge is not being accessed by the incubated companies, which allows actions turned to encouraging businesses in this context.

This article analyzes farmers' preferences for different nonindexed crop insurance alternatives, using discrete choice experiment data on cocoa farmers from southern Ghana. We examine farmers' attendance to attributes by comparing self-reported attribute nonattendance (ANA) to the behavior inferred from the choices.

We utilize the latent class endogenous attribute attendance (EAA) model to address potential endogeneity by jointly modelling farmers' attribute processing strategies with their choice of attributes of the insurance products.

The results show that premium levels, mode and length of indemnity payouts tend to influence farmers' preferences for crop insurance products. The findings also reveal that credit-constrained farmers attend more to premium and payment mode attributes of the crop insurance products and that credit-constrained farmers tend to exhibit lower willingness-to-pay estimates for the crop insurance attributes.

The findings from the study suggest that credit constraints do not only limit input use, but also tend to have statistically significant impact on farmers' cocoa insurance participation decisions.

The study examines the impact of credit constraints on farmers' crop insurance preferences while accounting for ANA.

Businesses are increasingly called upon to support the improvement of society and the environment, and one way to do so is by expanding into international markets, particularly through exports. Despite the importance and recognised challenges of a global approach to sustainable value creation, sustainability research tends to focus on domestic contexts. This paper aims to identify the boundary conditions linking sustainable value creation practices with firm performance in the international context.

The authors merge the sustainable value creation and the international marketing literature to develop two propositions that capture the emerging nature of the field and the lack of concluding evidence regarding the link between international sustainable value creation practices and firm performance. The authors test these propositions empirically by analysing 519 responses to a survey of exporting firms in Portugal, using fuzzy-set qualitative comparative analysis.

The authors identify seven configurations that support sustainable value creation in an international context. These consist of varying levels of standardised and tailored offers, management experience and competitive intensity.

The identification of seven different configurations helps managers decide whether and how to innovate when pursuing sustainable value creation opportunities in international markets.

The authors propose that an effective way for governments to achieve national and transnational social and environmental agendas is to help businesses that pursue sustainable value creation to succeed in international markets. Given that four of the seven pathways to improve export performance that the authors identified require international management experience, the authors posit that an effective way to support the internationalisation of those businesses is through targeted training programmes and knowledge-sharing initiatives.

The authors respond to calls for research to integrate the sustainable value creation and the international marketing literatures, to identify how and when firms can create sustainable value creation in an international context and thus support the resolution of global, social and environmental problems. The finding that there are multiple configurations that support this goal explains why empirical evidence collected thus far is inconclusive and helps identify the boundary conditions of existing theory.

This study aims to investigate the relationship between market-oriented environmental sustainability (MES) and green export-related resources and capabilities, analyzes the impact of these resources and capabilities on the eco-friendly export marketing strategy and assess the influence of such strategy on export performance.

This study uses survey data from 241 manufacturing export firms analyzed through partial least squares structural equation modeling.

The results show a positive influence of MES on green export-related resources and capabilities. Further, while green export-related capabilities directly affect eco-friendly export marketing strategy, resources only influence it indirectly through capabilities. The results also show that the adoption of an eco-friendly export marketing strategy contributes to firm’s export performance.

This study makes an important contribution to sustainability and exporting literature by evaluating the behavior of firms in terms of MES and eco-friendly export marketing strategy.

The purpose of this paper is to analyze effects of absorptive capacity (ACAP) on organizational performance. The model looks at the mediating influence of marketing capabilities (innovative capability and new product development capability (NPDC)) and innovation performance (IP).

This study takes a quantitative approach by using survey data from 333 Brazilian manufacturer managers involved with strategic marketing processes. Structural equation modeling was used to test the theoretical hypotheses.

Results indicate that ACAP does not have a direct impact on organizational performance. The relation is fully mediated by marketing capabilities (innovative capability and NPDC) and IP.

According to the research findings, managers should put efforts in the ACAP as well as marketing capabilities that will result in better organizational performance. This research is limited to the context of manufacturer firms in Brazil. However, it is suggested that an application of this research can be conducted in different industries and different countries.

This study contributes to theory and management practice. First, no study has explored all these constructs together. Through the relationship between ACAP and performance, the authors found that marketing capabilities and IP can fully mediate the former proposed relation. The authors’ contribution is the understanding of the role of ACAP influence on performance. Managers should be encouraged to invest in companies’ ACAP as well as marketing capabilities to differentiate themselves from competitors and improve performance.

This paper aims to analyze how the legitimacy of the policy of external quality assurance (EQA) in Colombian higher education has evolved over the past 30 years through an examination of its two main instruments: the compulsory control of minimum quality standards for academic programs and institutions (registro calificado) and accreditations of excellence for programs and institutions.

Based on the methodology of process-tracing, this paper offers a review of the main sequences of the policy of EQA in Colombian higher education: the origins (1990–1998), the expansion (1998–2011) and the contestation (2011–2021). In each sequence, the sources of the substantive and procedural legitimacy of the policy are analyzed. This analysis is based on qualitative data comprising semi-structured interviews with key informants, online information from the 2011 and 2018 student protests and official documentation.

The policy of EQA in Colombian higher education had relatively high levels of substantive and procedural legitimacy during the first two sequences. However, the situation has become more ambivalent since 2011. On the one hand, internal contradictions and student movements’ growing criticism of neoliberal policies have undermined some of the foundations of this policy. On the other hand, higher education institutions and the Colombian Government still have a positive perception of EQA and have recently revisited the policy to address some of its shortcomings.

From a conceptual standpoint, this paper advances our understanding of how quality assurance in higher education gains, sustains or loses legitimacy by discussing and testing typologies of legitimacy in the analysis of a national system of EQA. From an empirical perspective, this paper provides a diachronic analysis of EQA in Colombian higher education, a case that has primarily been studied through a technical-rational perspective.

The commercialization of research produced by universities constitutes a core facet of academic entrepreneurship (AE). Academic literature reveals the need to shed light on entrepreneurial processes in higher education institutions (HEIs). This study intends to fill this gap by researching the mechanisms for facilitating AE and the variables that can moderate the relationship between such mechanisms and AE in Portuguese HEIs.

Our research model aims to assess the mechanisms of academic entrepreneurship (AE) within a sample of 125 Portuguese public higher education institutions (HEIs). To test our research hypotheses, we employed a structural equation model (SEM) using the partial least squares (PLS) method. Additionally, our evaluation examines the potential moderating effects of incubator programs, support initiatives, and proof-of-concept programs (PoCs). Our research model seeks to evaluate the mechanisms for facilitating AE and explore the effects of including incubator programs, support initiatives, and PoCs as moderators. The seven variables (Research mobilization, Unconventionality, Industry collaboration, University policies, Incubator programs and support initiatives, Proof-of-concept programs, and academic entrepreneurship) were measured using a 7-point Likert scale.

The results revealed that different drivers of AE influence the creation and development of entrepreneurial activities. Our findings also show the moderating effects of incubator programs, support initiatives, and proof-of-concept programs on AE. We find that incubator programs, other support initiatives, and PoCs maintain a moderating effect on AE and benefit their respective HEIs.

The study examines only the Portuguese HEI context. Therefore, generalizing these results necessitates reservations. However, the responses came from various actors in HEIs, from different academic backgrounds and research interests. This makes the results more generalizable. Limitations are evident in external validity, given that we gathered the data over a relatively short period.

Observed factors are explored to gain a deeper understanding of their influence on the mechanisms of AE. The implications arise from the new perspective presented and the methodology used to identify mechanisms capable of fostering AE. We hope this research will encourage other researchers to study this topic further.

the engagement of universities at the global level should be emphasised in future policy. While universities in innovation systems often have a local focus, their engagement in innovation ecosystems transcends the boundaries of geographic locations.

PoCs had a significant positive moderating effect on the impact of research mobilization and university policies on AE. Thus, we find interactions between universities and industry boost AE. This study demonstrates how AE benefits HEIs by extending orientation towards mobilizing research, unconventional approaches, cooperation with industry, and university policy implementation. We thus advocate a new approach, demonstrating the influence that the mobility of research, unconventionality, industry collaboration, and university policies hold over AE.

The purpose of this paper is to examine the cooperation between firms as an important phenomenon, particularly within entrepreneurial strategies. This paper describes the results of an empirical study about SMEs (small and medium‐sized enterprises) in the textile and clothing sector in Portugal. The results show that the level of cooperation between SMEs is limited in extent. When cooperation exists between the firms, the empirical results obtained reveal a great number of agreements in the production area so that subcontracting is the form of collaboration most commonly adopted. The SMEs prefer to cooperate with local firms because they know each other and share the same cultural background. The empirical results also allow us to conclude that the cooperative agreements are mainly informal; and that their stability is ensured and guaranteed by trust and communication between the partners.
