The purpose of this paper is to analyze the aerodynamic improvements obtained in a wing section with a NACA 0018 airfoil manufactured using the fused deposition modeling (FDM) technique with regard to a smooth surface made by milling. The creation of micro-riblets on the surface of the airfoil, due to the deposition of the material layer by layer, improves the general aerodynamic performance of the parts, provided that the riblets are parallel to the flow line. The incidence of the thickness of the thread deposited in each layer – to be the variable on which the geometry of the riblets is based – was studied.

The wing section was designed using 3D software. Three different models were designed by rapid prototyping, using additive and subtractive manufacturing. Two of the profiles were manufactured using FDM varying the thickness of the layer to be able to compare the aerodynamic improvements. The third model was manufactured using a subtractive rapid prototyping machine generating a smooth surface profile. These three models were tested inside the wind tunnel to be able to quantify the aerodynamic efficiency according to the geometry and the riblets size.

The manufacture of an aerodynamic profile using FDM provides, in addition to the lightness and the ability to design parts with complex geometries, an improvement in the aerodynamic efficiency of 10 per cent compared with profiles with a smooth surface.

With the aerodynamic advantage gained through the use of FDM positions, the additive manufacturing serves as an excellent alternative for the manufacture of lightweight aerodynamic parts, with low structural loading and with low Reynolds number (∼5·105). This technological advantage would be applied to the UAV (unmanned aerial vehicle) industry.

The study carried out in this article demonstrates that the use of FDM as a manufacture process of end-used parts that are subject to movement generates an additional advantage that had not been considered. The additive manufacturing allows us to directly manufacture riblets by creating the necessary surface so as to reduce the aerodynamic drag.

The purpose of this paper is to provide a systematic literature review of the research published on financial inclusion (FI) and financial exclusion (FE) in developed countries using key terms and strict inclusion and exclusion criteria.

In total, 52 papers were deemed to be relevant to the analysis. These works were critiqued using a framework that addressed geographical contexts, topics, methodologies and theoretical frameworks.

This review highlights the uneven level of development of the academic debate between North America, the UK and continental Europe, and identifies the different theoretical frameworks that construe the body of literature in each region. In addition, the findings show the scant offer of work on the impact that the digital economy has on FE, as well as the reduced number of studies which have focused on certain vulnerable groups and the access to some financial services.

The studies reviewed have not analyzed the specific needs of vulnerable groups while considering the different contexts and pathways to exclusion. The evaluation of solutions and strategies to achieve inclusion is one of the least addressed aspects in the literature.

The paper synthesizes the main contributions of the top literature on the redefinition of FI/FE in developed countries, the role of fringe services and new determinants of exclusion. The proliferation of studies regarding FI in low- and middle-income countries has generated a great amount of meta-analysis and systematized reviews of asymmetric results. However, no systematized literature review on the broad scope of FI/FE in developed countries has been published in the last decade. This work sheds light over poorly analyzed areas of research that refer to notable social problems.

Due to the global COVID-19 pandemic, UNESCO Landscapes and World Heritage sites have faced unstable situations. Both at the sites themselves and in the research centres, universities and even the homes of the people involved, they have acted and responded to the best of their ability. In this context, the aim of the comparative analysis of different cases carried out here is to understand the main effects of the pandemic in the short term. On the one hand, the purpose is to determine what the general response trends have been and, on the other, to measure the resilience capacity in each case.

Up to eight cases studies representing different and diverse kinds of Heritage and Protected Natural sites from Southern Europe and America are compared.

In a context of uncertainty, new responses, unique opportunities and hitherto unseen weaknesses have arisen in research and management of natural and cultural heritage. In general terms, the dialogue between officials, technicians and researchers that have put together this article underlines the need to work towards a governance model that engages everyone in dialogue. Discrepancies between overlapping strategies and plans, which is the main conflict detected, should be avoided while a decentralisation of policies could be more operational. In this sense, situated knowledge may be of help in configuring practical management tools.

This paper compares and contrasts for first time the effects of the pandemic in Europe and Latin America. This exercise has provided a valuable diagnostic for present and future heritage management.

Stakeholder theory may be the Archimedes lever that allows defining a possible Economy for the Common Good; however, the theory’s current level of development does not enable it to escape the criticism that considers it nothing more than shared egoism. The expansion of the concept of stakeholder, including not only groups that collaborate in the creation of value or which are actively impacted by the organisation, but also incorporating those affected by omission – non-stakeholders – would lead to the reconciliation of stakeholder theory and the common good. Nevertheless, to set it within corporate practice, besides having selfish and altruist incentives, would be of interest for the conceptual development of shapeholders, understood as the link between non-stakeholders’ interests and needs, and firms.

Total Productive Maintenance (TPM) could act as a practical approach to offer sustainability deliverables in manufacturing firms aligning with the natural resource-based view (NRBV) theory's strategic capabilities: pollution prevention, product stewardship and sustainable development. Also, the emergence of Blockchain Technology (BCT) and Circular Economy (CE) are proven to deliver sustainable outcomes in the past literature. Therefore, the present research examines the relationship between BCT and CE and TPM's direct and mediation effect through the lens of NRBV theory.

The current study proposes a conceptual framework to examine the relationship between BCT, CE and TPM and validates the framework through the Partial Least Squares Structural Equation Modeling. Responses from 316 Indian manufacturing firms were collected to conduct the analysis.

The investigation outcomes indicate that BCT positively influences CE and TPM and that TPM has a significant positive impact on CE under the premises of NRBV theory. The results also suggest that TPM partially mediates the relationship between BCT and CE.

This research fills a gap in the literature by investigating the effect of BCT and TPM on CE within the framework of the NRBV theory. It explores the link between BCT, TPM and CE under the NRBV theory's strategic capabilities and TPM mediation.

The positive influence of TPM and BCT on CE could initiate the amalgamation of BCT-TPM, improving the longevity of production equipment and products and speeding up the implementation of CE practices.

This research fills a gap in the literature by investigating the effect of BCT and TPM on CE within the framework of the NRBV theory. It explores the link between BCT, TPM and CE under the NRBV theory's strategic capabilities along with TPM mediation.

The purpose of this study is to analyze interlocking directorate (ID) networks of family and nonfamily firms (FFs) in Chile, Mexico and Peru.

Social network analysis methodology allowed us to analyze the position of FFs within the structure of IDs at the local and transnational levels.

FFs tend to have a higher proportion of board interlocks to other firms, especially FFs. In addition, FFs are more likely to occupy a brokerage position in national IDs structures. Finally, they also have a higher proportion of interlocks to other domestic firms in and nearby geographic areas. Thus, they create transnational networks.

This paper finds evidence that supports three of the premises of interorganizational familiness literature (Lester and Cannella, 2006). FFs are part of national as well as international corporate networks more than other types of firms, through interlocking directorships.

Analizar redes de consejeros de empresas familiares y no familiares en Chile, México y Perú.

El análisis de redes sociales nos permitió analizar la posición de empresas familiares dentro de la estructura de redes a nivel local y transnacional.

Las empresas familiares tienen un nivel más alto de entrecruzamientos con otras empresas, especialmente con las familiares. Además, las empresas familiares son mas propensas a ocupar posiciones de intermediación en las estructuras nacionales de redes. Finalmente, también tienen más entrecruzamientos con otras empresas nacionales y en regiones geográficas cercanas por lo que crean redes transnacionales.

Encontramos evidencia que apoya los tres pilares de la literatura de familiaridad interorganizacional (Lester y Cannella 2006). Las empresas familiares son parte de una red nacional e internacional más que otros tipos de empresas a través de las interconexiones de posiciones en consejos.

A análise das redes sociais permitiu analisar a posição das empresas familiares na estrutura das redes a nível local e transnacional.

As empresas familiares têm um nível mais elevado de ligações cruzadas com outras empresas, especialmente as empresas familiares. Além disso, é mais provável que as empresas familiares ocupem posições intermediárias nas estruturas das redes nacionais. Por último, têm também mais referências cruzadas com outras empresas nacionais e em regiões geográficas próximas, pelo que criam redes transnacionais.

Encontramos evidências que sustentam os três pilares da literatura sobre familiaridade interorganizacional (Lester e Cannella 2006). As empresas familiares fazem parte de uma rede nacional e internacional mais do que outros tipos de empresas através do interconexões de cargos nos conselhos de administração.

The purpose of this paper is to examine theoretically and empirically what type of leadership facilitates e-business adoption in large manufacturing firms. The digital transformation of firms requires leadership that can promote the adaptive quality of organizational culture.

The authors conducted an empirical study using two key informants from a sample of 181 incumbent firms.

The authors find significant evidence that adaptive culture is the vehicle by which transformational leaders positively influence e-business adoption.

Given the digital economy’s external pressures, many e-business adoption processes fail due to organizational factors originating in leadership and its capability to change followers’ values, norms, and motivations. To solve this problem, the authors propose a model that explains how transformational leadership first plays a key role in changing characteristics of culture and then facilitates e-business adoption.

This study contributes to the limited literature on crowdlending by providing a data-driven analysis of the sector. A synthetic DP2 indicator is proposed to identify the leaders of the crowdlending market, the key factors behind their success and the medium-term competitive implications.

The study examines 17 crowdlending platforms and eight performance indicators. The information provided by these indicators is aggregated using a synthetic indicator based on the P₂ Distance (DP2) method.

Mintos, Evoestate, Peerberry, Bondster and Fellow Finance are the leading platforms. This method reveals the key variables in the identification of market leaders, namely year-on-year variation in the number of investors and year-on-year variation in lending per investor. The leaders in terms of lending volumes should not take their current situation for granted. Small and medium-sized platforms are pushing hard and may overtake the incumbents as market leaders.

Financial intermediation through crowdlending is becoming an increasingly popular alternative to traditional models. Changes in the sector are expected in the coming years due to the rise of platforms with a moderate amount of lending and solid year-on-year improvement. To become leaders and to attract both lenders and borrowers, platforms are encouraged to improve the information that they provide.

This paper offers the first analysis of market leadership in the crowdlending sector. It analyses the competitive market of the crowdlending sector based on its actors and key factors. These factors explain the differences in the market position of different platforms. Based on this analysis, the trends in this sector can be identified. This study is exploratory, so it offers empirical data that can be useful in the development of theories that apply to the sector.

The main purpose of this study is analyzing the influence of corporate social responsibility practices and programs on employee human resources performances in Puerto Rico. The study used an exploratory approach and primary data for this research was obtained through a questionnaire collected from 205 employees of companies with CSR active programs. The study uses structural equation model (SEM) technique to test the hypotheses. The study found the highest significantly positive relationship in CSR programs and employee human resources performances than CSR practices and employee human resources performances. The present study discusses important implications regarding uses of CSR for enhancing employee’s organizational commitment and satisfaction. One of the least studied areas at the moment is the internal corporate social responsibility which is directly related to company’s employees. This dimension of the corporate social responsibility refers to the set of responsible activities and practices that the company realizes toward their employees that consider the living conditions of each one of them and the contribution that it can do to improve their well-being.

The perception of costs and benefits allows residents to carry out an assessment that determines their attitude towards tourism. This study seeks to determine the effect of the perceived benefits and costs (economic, sociocultural and environmental) on the support to the arrival of more tourists, both directly and mediated by overall attitude towards tourism, in the case of Punta del Este. Punta del Este forms part of the Department of Maldonado and is the main sun and beach tourism destination in the Oriental Republic of Uruguay. The questionnaire contained items with five-point Likert scales and sociodemographic questions. The data used (obtained between March and August 2016) are made up of a sample of 420 residents from Maldonado and Punta del Este. The analysis of the data has been carried out through partial least squares (PLS) regression, specifically SmartPLS. Among the results, it should be noted that benefits and costs perceived have no direct effect on the support to the arrival of more tourists; only economic benefits (positive) and sociocultural costs (negative) have a significant effect on the overall attitude towards tourism; the support to the arrival of more tourists depends exclusively on the overall attitude.
