Abstract
Purpose
Herein, the authors report the effects of printing parameters, joining method, and annealing conditions on the structural performance of fusion-joined short-beam sections produced by additive manufacturing.
Design/methodology/approach
The authors first identified appropriate printing parameters for joining segmented short beams and then used those parameters to print and fusion-join segments with different configurations of stiffeners to form a longer section of a wing or small wind turbine blade structure.
Findings
It was found that the beams with three lateral and three base stiffening ribs give the highest flexural strength among the three beams investigated. Results on joined beams annealed at different conditions showed that annealing at 70 °C for 0.5 h yields higher performance than annealing at the same temperature for longer times. It is also found that in the case of the hot-plate-welded three-dimensional (3D)-printed structures, no annealing is needed for reaching a high strength-to-weight ratio, but annealing is helpful for maximizing the modulus-to-weight ratio. Both thermal buckling and edge wrapping were observed under annealing at 70°C for 0.5 h for 3D-printed beams comprising two lateral and four base stiffening plates.
Originality/value
Fusion-joining of additively manufactured segments is needed owing to the constraint in building volume of a typical commercial 3D-printer. However, study of the effect of process parameters is needed to quantify their effect on mechanical performance. This investigation has therefore identified key printing parameters and annealing conditions for fusion-joining short segments to form larger structures, from multiple 3D-printed sections, such as wind blade structures.

Abstract
Purpose
The purpose of this paper is to investigate the moderating effect of ownership on the links between corporate governance and financial performance in the context of Ghanaian banks.
Design/methodology/approach
The current study used a sample of 23 banks and the multiple regression method to analyze a panel dataset of 414 from banks over an 18-year period.
Findings
The findings revealed that audit independence, chief executive officer (CEO) duality, non-executive directors and banks size have a positive impact on performance. The findings also revealed that foreign ownership has an interacting effect between corporate governance and profitability.
Practical implications
The practical implications of the current study demonstrated that good corporate governance creates value and must be invigorated for the interest of all stakeholders. Foreign ownership has an interacting effect between corporate governance and performance. Policymakers should formulate policies for attracting foreign investors.
Originality/value
Interestingly, this study is the first of its kind that exclusively chose ownership structure to interact between corporate governance and bank performance in Ghanaian perspective. Such new insights on this relationship provide useful information to the government, academics, policymakers and other stakeholders. The growing economies of African countries, and the inadequate governance–performance literature in African context, have created a demand to appreciate the governance parameters in these countries and its influence on firm's performance.

Abstract
Purpose
The purpose of this study is to theoretically hypothesise and empirically explore the relationships between operations and supply chain management (O&SCM) and marketing/sales (OMS) collaboration, social media (SM) usage, organisational resilience and performance. This paper considers how collaboration through SM can enhance organisational resilience capability and performance.
Design/methodology/approach
A survey was conducted among 395 organisations in the UK. Structural equation modelling was applied to test the research hypotheses.
Findings
The empirical findings of this study support the significant mediating role of O&SCM–OMS collaborative activities through internal and external SM for better organisational resilience, capability, cost efficiency, customer-focused and business performance. This also extends to exploring differences based on product versus service industries.
Originality/value
Through empirical research, the findings contribute to the theoretical development and managerial guidance on O&SCM–OMS collaboration and resilience capability by emphasising the strategic deployment of SM across functions through the lens of contingency theory and resource-based view.

Abstract
Purpose
From the agency theory’s point of view, this paper aims to analyze corporate governance mechanisms about the characteristics of the companies quoted in the segments Bovespa Mais and Bovespa Mais 2 and their influence on the creation of value in preparation for the opening of the initial public offering (IPO).
Design/methodology/approach
A quantitative approach was adopted to achieve the proposed objective using the panel data with fixed effects and secondary data collected on the Comissão de Valores Mobiliários website, using statistical software Stata® 13.0 for statistical tests. The population comprises non-financial companies belonging to the Bovespa Mais and Bovespa Mais Level 2 groups, as the survey sample took into account the period of adhesion of the companies, totaled in 15 companies, which cover the period from 2008 to 2019. The selected variables correspond to the ownership structure’s characteristics, then the board’s composition and the fiscal council as the body responsible for supervising the administrators’ acts.
Findings
The main results indicate that the number of independent members on the board of directors and the supervisory board’s participation positively influence market performance. However, it also reveals that the concentration of ownership brings fundraising for other companies’ acquisitions, risk reduction concerning information asymmetry between investing powers.
Research limitations/implications
The main results indicate that the number of independent members on the board of directors and the supervisory board’s participation positively influence market performance. Despite this, it also reveals that the concentration of ownership brings fundraising for other companies’ acquisitions, risk reduction concerning information asymmetry between investing powers.
Practical implications
This paper advances a comparative institutional perspective to explain capital market choice by firms making an IPO in a foreign market. This paper finds that internal governance characteristics (founder-chief executive officer, executive incentives and board independence) and external network characteristics (prestigious underwriters, degree of venture capitalist syndication and board interlocks) are significant predictors of foreign capital market choice by foreign IPO firms.
Social implications
While product market choices have been central to strategy formulation for firms in the past, financial markets’ integration makes capital markets an equally crucial strategic decision. This paper advances a comparative institutional perspective to explain capital market choice by firms making an IPO in a foreign market.
Originality/value
This situation generates value to shareholders and is perceived by the market and, ultimately, generates a direct relationship with the market performance of companies. While product market choices have been central to strategy formulation for firms in the past, financial markets’ integration makes capital markets an equally major strategic decision.

This study aims to explore the impact of different contextual factors and their interactions on university students' entrepreneurship, specifically start-up activities.
Abstract
Purpose
This study aims to explore the impact of different contextual factors and their interactions on university students' entrepreneurship, specifically start-up activities.
Design/methodology/approach
The paper used a multilevel hierarchical model with four contextual factors: i) industry and technological, ii) institutional and policy, iii) organizational-university; and iv) cultural. Each of these factors might influence university students’ start-up activities differently. To address this exploratory direction, the study used a sample of 34,200 nascent entrepreneurs from 34 countries included in the Global University Entrepreneurial Spirit students’ Survey, along with data from the World Economic Forum’s Global Competitiveness Index, Global Entrepreneurship Index and Global Leadership and Organizational Behavior Effectiveness Index.
Findings
The results show that, in general terms, contextual elements impact university students’ start-up activities. Nevertheless, when these factors are combined, their effect increases strongly with the performance-based culture but decreases with a high level of a socially supportive culture.
Originality/value
Regarding the study of university students’ start-up activities, most scientific evidence has an individual-level approach without considering the influence of the context. The paper adopts a multilevel approach for such analysis to reflect the multilevel and context-dependent nature of the topic under study.
Propósito
Este estudio explora el impacto de diferentes factores contextuales y sus interacciones en el espíritu empresarial de los estudiantes universitarios, concretamente en las actividades de puesta en marcha.
Diseño/metodología/enfoque
El trabajo emplea un modelo jerárquico multinivel con cuatro factores contextuales: i) industriales y tecnológicos, ii) institucionales y políticos, iii) organizativos-universitarios; y iv) culturales. Cada uno de estos factores podría influir de forma diferente en las actividades de puesta en marcha de los estudiantes universitarios. Bajo un enfoque exploratorio, el estudio utilizó una muestra de 34.200 emprendedores nacientes de 34 países incluidos en la Encuesta Global de Estudiantes Universitarios con Espíritu Emprendedor (GUESSS por sus siglas en inglés), junto con datos del Índice de Competitividad Global (GCI), el Índice de Espíritu Emprendedor Global (GEI) y el Índice Global de Liderazgo y Eficacia del Comportamiento Organizacional (GLOBE).
Hallazgos
Los resultados muestran que, en términos generales, los elementos contextuales influyen en las actividades de creación de empresas de los estudiantes universitarios. Sin embargo, cuando se combinan estos factores, su efecto aumenta considerablemente en países con una cultura basada en el rendimiento, pero disminuye en las de un alto nivel de apoyo social.
Originalidad/valor
En lo que respecta al estudio de las actividades de creación de empresas de los estudiantes universitarios, la mayoría de las pruebas científicas tienen un enfoque a nivel individual sin tener en cuenta la influencia del contexto. Nuestro trabajo adopta un enfoque multinivel para dicho análisis con el fin de reflejar la naturaleza multinivel y dependiente del contexto del tema estudiado.
Objetivo
Este estudo explora o impacto de diferentes fatores contextuais e suas interações no empreendedorismo dos estudantes universitários, especificamente nas atividades de start-up.
Desenho/metodologia/abordagem

Cada um desses fatores pode influenciar de maneira diferente as atividades de start-up dos estudantes universitários. Para abordar essa direção exploratória, o estudo utilizou uma amostra de 34.200 empreendedores de 34 países incluídos na Pesquisa Global sobre o Espírito Empreendedor dos Estudantes Universitários (GUESSS), juntamente com dados do Índice de Competitividade Global (GCI) do Fórum Econômico Mundial, do Índice Global de Empreendedorismo (GEI) e do Índice de Liderança Global e Eficácia Organizacional (GLOBE).
Resultados
Os resultados mostraram que, em termos gerais, elementos contextuais impactam as atividades de start-up dos estudantes universitários. No entanto, quando esses fatores são combinados, seu efeito aumenta fortemente com a cultura baseada em desempenho, mas diminui com um alto nível de cultura socialmente solidária.
Originalidade/valor
No que diz respeito ao estudo das atividades de start-up dos estudantes universitários, a maioria das evidências científicas tem uma abordagem em nível individual sem considerar a influência do contexto. Nosso artigo adota uma abordagem multinível para tal análise, a fim de refletir a natureza multinível e dependente do contexto do tema em estudo.

Abstract
Purpose
This study adopts the perspective of dynamic capabilities to investigate influencing factors and proposes improvement strategies of supply chain resilience of prefabricated construction.
Design/methodology/approach
The structural equation model (SEM) is used to identify and verify the relationship between factors influencing supply chain resilience of prefabricated construction from the perspective of dynamic capabilities. The system dynamics (SD) model is constructed to dynamically simulate the specific effects of different influencing factors.
Findings
Results indicate that: (1) An evaluation index system for supply chain resilience of prefabricated construction containing five first-level indicators and 36 second-level indicators is constructed; (2) Ability to anticipate, ability to respond, ability to adapt, ability to recover and ability to learn are positively correlated with the supply chain resilience of prefabricated construction and (3) ANT3 (information system), RES1 (quick response), ADA3 (buffer stock) and LEA4 (trust) are the most leading factors influencing supply chain resilience of prefabricated construction over time.
Originality/value
This study fulfills the need for an in-depth exploration of the various influencing factors on supply chain resilience of prefabricated construction from the perspective of dynamic capabilities. Furthermore, this study provides improvement strategies to enhance supply chain resilience of prefabricated construction in China.
