Abstract
Purpose
This paper aims to investigate the quality of printed surfaces and manufacturing tolerances by comparing the cylindrical cavities machined in parts obtained by fused deposition modeling (FDM) with the holes manufactured during the printing process itself. The comparison focuses on the results of roughness and tolerances, intending to obtain practical references when making assemblies.
Design/methodology/approach
The experimental approach focuses on the comparison of the results of roughness and tolerances of two manufacturing strategies: geometric volumes with a through-hole and the through-hole machined in volumes that were initially printed without the hole. Throughout the study, both alternates are explained to make appropriate recommendations.
Findings
The study shows the best combinations of technological parameters, both machining and three-dimensional printing, which have been decisive for obtaining successful results. These conclusive results allow enunciating recommendations for use in the industrial environment.
Originality/value
This paper fulfills an identified need to study the dimensional accuracy of the geometries obtained by additive manufacturing, as no experimental evidence has been found of studies that directly address the problem of the FDM-printed part with geometric and dimensional tolerances and desirable surface quality for assembly.

Abstract
Purpose
A structured customer-driven and integrative methodology to develop materials is described. The proposed methodology is aimed to drive analysis and prioritization of the multiple variables involved in a new application case for 3D printing, which involves the development of a new alumina-starch-based powder.
Design/methodology/approach
The development of new powder mixture designed for 3D printing of refractory supports for metal casting moulds is presented. The quality function deployment (QFD) method was applied. Inputs for QFD analysis were found using total quality management tools. Using this approach, six process and material variables were considered to drive a prioritization analysis using a Plackett-Burman Design of Experiment (DOE) array. As performance parameter, compressive resistance was measured and assessed.
Findings
QFD analysis delivered standardized procedures, irrelevant factors and target values for intermediate step parameters. Sintering parameters were found to be the most influencing over compressive resistance.
Research limitations/implications
The methodology was based upon a materials development case for 3D printing.
Practical implications
Knowing in advance the influence of every affecting factor of the process provides a closer control on variability of final part properties, which is a key issue to launch parts into industrial applications. Quality planning and documentation in advanced is the basis for all the quality system of the new additive manufacturing (AM) process to be created.
Originality/value
Procedures for quality planning and control were proposed. This study, as methodological research, intends to introduce industrial engineering practices and quality management routines for AM material/process developers.

Abstract
Purpose
The objective of this paper is to analyze the country-level causal configurations of digital enablers that result in entrepreneurial innovation in new ventures. Entrepreneurial innovation is a complex phenomenon that draws on a combination of context-dependent causal conditions, which explain the configurations of external factors that integrate into the entrepreneurial process. In this paper, we focus on the contextual role of information and communication technologies (ICT) from an organizational center-edge approach.
Design/methodology/approach
This study employs case-oriented techniques, specifically fuzzy-set qualitative comparative analysis (fsQCA) and necessary condition analysis (NCA), to identify the necessary and sufficient conditions that lead to entrepreneurial innovation. A dataset comprising 61 countries was merged from the World Economic Forum’s Networked Readiness Index and the Global Entrepreneurship Monitor in order to explore the causal combinations of ICT adoption, online transactions business-to-business, business model innovation and organizational innovation.
Findings
The fsQCA demonstrates that entrepreneurial innovation can be attributed to two causal configurations. The first configuration includes ICT adoption, online business-to-business transactions and the absence of organizational innovation. The second configuration is characterized by ICT adoption, online business-to-business transactions and business model innovation. The NCA reveals that the conditions in question possess varying degrees of importance, with each condition exerting a distinct degree of influence on the generation of varying levels of entrepreneurial innovation. The case-oriented techniques employed in this research paper have yielded preliminary insights into the relationship between digital enablers and entrepreneurial innovation, particularly in groups of countries with varying degrees of necessity to these enablers.
Practical implications
Our research provides a framework for the development of more effective digital strategic mixes for each identified group of countries. It also raises theoretical questions about the national conditions that encourage a particular digital enabler to stimulate a specific form of entrepreneurial innovation in new ventures.
Originality/value
In lieu of pursuing definitive causal explanations, this study proposes alternative configurations. While fsQCA demonstrates that entrepreneurial innovation is contingent upon distinctive causal conditions, extending the analysis to NCA reveals the level of necessity required for a condition to yield varying degrees of entrepreneurial innovation. The integration of fsQCA and NCA offers a more nuanced understanding of context-dependent factors that define entrepreneurial innovation in new ventures than fsQCA alone.

Abstract
Purpose
The purpose of this paper is to find throughout history examples of wealth management of a family or business families that can be assimilated into the current concept of family offices (FOs). In such examples, the study identifies characteristics associated with the different dimensions of the concept of socioemotional wealth (SEW).
Design/methodology/approach
Drawing on the socioemotional perspective, this paper relates significant examples of FOs based on historical stages (ancient history, the middle ages, modern history, the contemporary period and the actual world). Each case is discussed with an effort to identify the dimensions of the SEW that fit and help in understanding the organization studied.
Findings
Mainly, FOs allow the management of the family legacy, philanthropy, promotion of entrepreneurship and family wealth preservation for future generations. Autonomy in decision-making, privacy and confidentiality and the achievement of more intangible goals make the FO preferable to other institutions. Through the study of historical cases, the FO constitutes a structure with objectives and activities that have remained consistent from Rome to the present, regardless of historical, political or social context. The results also identify four out of five FIBER dimensions of SEW.
Originality/value
In addition to contributing to the scarce literature on FOs, this paper uses various examples of historical periods to better understand its origin, evolution and current state. A selection of examples at different times allows us to verify that FOs undergo a series of changes throughout history but maintain their characteristics regardless of the historical context. This paper is the first to explore the origin and development of the FO as organization. Building on the findings, the authors present a conceptual SEW framework to deepen in the knowledge of FO. This framework could help researchers and practitioners in future researches providing a conceptual link that demonstrates the components of the SEW perspective best fit the objectives pursued by business families when establishing a family office.

Abstract
Purpose
The purpose of this study is to analyze the intentions and use behavior of digital learning environments in business education under the COVID-19 pandemic. Digital learning environments (DLEs) are ready to use bundles of heterogeneous educational technologies used by schools to deliver online courses that contrast to traditional packaged learning management systems. Through the merger of Technology Readiness Index and Unified Theory of Adoption and Use of Technology, a nuanced perspective on the adoption of DLEs under the COVID-19 pandemic is achieved.
Design/methodology/approach
A cross-sectional survey study gathered sample data from Mexico, Malaysia and Spain to assess the effect of broad perceptions on technology and specific technologies embedded in DLEs. Data were analyzed using structural equation models and multigroup analysis.
Findings
Student optimism and innovativeness play a critical role in assessing specific features of DLEs. Discomfort and insecurity as barriers to adoption play a minor role. Performance expectancy has a strong effect on behavioral intention to use DLEs, but the effect of effort expectancy is nonsignificant. Multigroup analysis shows significant differences in technology perceptions between samples from Malaysia versus Mexico and Spain.
Practical implications
DLEs help students complete their academic tasks in online and hybrid settings. Instructors can take advantage of students’ positive perceptions of technology to set up DLE use in classrooms. They need to focus on the facilitating conditions of specific technologies and on learning outcomes that remain more important than learning how to use specific technologies.
Originality/value
Technology adoption studies usually rely on only one model, and this is one of the few studies that merge Technology Readiness Index and Unified Theory of Adoption and Use of Technology models. The results of this study support a comprehensive view of individual perceptions of technology and specific attributes of DLEs and their effects on behavioral intentions in relation to DLEs.

Abstract
Purpose
Strategic planning (SP) enables enterprises to plan management and operations activities efficiently in the medium and large term. During its implementation, many processes and methods are manually applied and may be time consuming. The purpose of this paper is to introduce an automatic method to define strategic plans by using text mining (TM) algorithms within a generic SP model especially suited for small- and medium-sized enterprises (SMEs).
Design/methodology/approach
Textual feedbacks were collected through a SWOT matrix during the implementation of a SP model in a company dedicated to the local distribution of food. A four-step TM process (performing acquisition, pre-processing, processing, and validation tasks) is applied via a framework developed under the cloud computer paradigm in order to determine the strategic plans.
Findings
The use of categorization and clustering algorithms show that unstructured textual information produced during the SP can be efficiently processed and capitalized. Collected evidence reveals the potential to enhance the strategic plans creation with less effort and time, improving the relevance, and producing new technological resources accessible to SMEs.
Originality/value
An innovative framework especially suited for the SMEs based on the synergy assumption of the coupling between TM and a generic SP model.

Abstract
This chapter investigates the environmental behaviours of three, four- and five-star hotels in Azuay (Ecuador). The methodology involved a quantitative research that measured the relationship between environmental responsibility (Gallardo, Sanchez, & Corchuelo, 2013) and stakeholder engagement (Kostova & Roth, 2002; Llamas-Sanchez, García-Morales, & Martin-Tapia, 2013; Vargas-Sánchez & Riquel-Ligero, 2012). The main findings suggest that the managers of the hotels implement environmental practices as they reduce waste, gas emissions and recycle materials. These practices are aligned with Ecuador’s extant legislation and regulations. In conclusion, this contribution implies that the hotels’ managers ought to communicate about their environmental responsibility with their stakeholders, including the employees, suppliers and customers.
