The purpose of this study is to investigate how the amount of material used and printing parameters affect the mechanical and water sorption properties of acrylonitrile butadiene styrene printed parts.

The specimens were printed using different printing parameters such as shell number, infill pattern and printing orientation, while accounting for the amount of material used. The mechanical properties of the printed parts were then evaluated using tensile, compression and flexural tests, along with sorption tests.

The results revealed that the maximum tensile stress of 31.41 MPa was obtained when using 100% infill and a horizontal printing orientation. Similarly, the maximum flexural strength and compression of 40.5 MPa and 100.7 MPa, respectively, were obtained with 100% infill. The printing orientation was found to have a greater impact on mechanical behavior compared to the number of shells or infill patterns. Specifically, the horizontal printing orientation resulted in specimens with at least 25% greater strength compared to the vertical printing orientation. Furthermore, the relationship between the amount of material used and strength was evident in the tensile and flexural tests, which showed a close correlation between the two.

This study’s originality lies in its focus on optimizing the amount of material used to achieve the best strength-to-mass ratio and negligible water infiltration. The findings showed that specimens with two shells and a 60% infill density exhibited the best strength-to-mass ratio.

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

The purpose of this two-part study is to systematically review, analyze and critically synthesize the current state of empirical research on knowledge loss induced by organizational member turnover (KLT).

This study is based on using a systematic literature review methodology reported in Part I.

Part II of this study contributes to the advancement of KLT scholarship by offering: an integrative narrative of KLT coping and preventive mechanisms as well as factors affecting them; an organizing framework of KLT empirical literature; and suggestions for future research, which are discussed with respect to the content, based on the proposed framework and by extending contextual dimensions of “who”, “where” and “when”, as well as use of theories and methods.

This study has limitations related to inclusion/exclusion criteria used for creating the review sample and the “Antecedents–Phenomenon–Outcomes” logic used to synthesize the findings.

A systematic literature review was conducted based on 91 empirical studies on KLT.

Part I of the study contributes to the advancement of KLT scholarship by mapping key developments in empirical research on KLT (publication trends, methodological and theoretical foci, heterogeneity of geographical, industrial and organizational contexts); encapsulating KLT antecedents associated with both voluntary and involuntary turnover; and revealing a broad scope of KLT effects at organizational and unit level.

This study has limitations related to inclusion/exclusion criteria used for creating the review sample and the “Antecedents–Phenomenon–Outcomes” logic used to synthesize the findings.

Part I of the study offers a systematic synthesis of KLT empirical research with respect to KLT antecedents, outcomes and factors affecting them.

After World War II, an educational modernization process gained ground worldwide. International organizations such as UNESCO began to play a key role in the creation, development and dissemination of a new educational vision in different countries. This article examines the origin and development of this modernization process under the dictatorship of Franco. More specifically, we will show how the adoption of this conception in Spain must be understood from the perspective of the interaction between UNESCO and Franco's regime, and how the policies of the dictatorship converged with the proposals suggested by this international organization. Our principal argument is that the educational policies carried out in Spain throughout the second half of the 20th century can be better understood when inserted into a transnational perspective in education.

This article uses documents from archives that until now were unpublished or scarcely known. We have also analyzed materials published in the preeminent educational journals of the dictatorship, such as the Revista de Educación, Revista Española de Pedagogía, Bordón and Vida escolar, as well as documents published by the Spanish Ministry of National Education.

Franco's dictatorship built an educational narrative closely aligned with proposals put forward by UNESCO on educational planning after World War II. The educational policies created by the dictatorship were related to the new ideas that strove to link the educational system with economic and social development.

This article is inspired by a transnational history of education perspective. On the one hand, it traces the origins of educational modernization under Franco's regime, which represented a technocratic vision of education that is best understood as a result of the impact that international organizations had in the second half of the 20th century. On the other hand, it follows the intensifying relationship between the dictatorship and the educational ideas launched by UNESCO. Both aspects are little known and studied in Spain.

The purpose of this paper is to address the potential impacts of Industry 4.0 on human resource management (HRM) – with a particular focus on employment, job profile and qualification and skill requirements in the workforce – which can have implications for supply chain management (SCM). Consequently, exploratory relationships among Industry 4.0, HRM and SCM are presented based on a systematic review.

To explore Industry 4.0 literature and its impact on employment, the authors used a systematic literature review to identify, classify and analyze current knowledge, flagging trends and proposing recommendations for future research in this area. Using the Web of Science database, the authors utilized co-citation software to visualize the networks which emerged from recurrent terms and which were then used to develop the categories of analysis.

The authors can affirm that the literature in this field is in a transition process, from the early studies of German academics to the current development of new impacts worldwide. Industry 4.0 is the central theme of the literature analyzed and is accomplished through the development of employment, qualifications, skills and learning frameworks. The results reveal that most papers are conceptual, with quantitative studies still lacking. Developed countries have a leading role in terms of research production, while Latin America and Asia are far behind. Clustering reveals four dominant themes (educational changes, employment scenario, work infrastructure resources and work meaning and proposal). The first refers to labor changes around working conditions, the work environment and new skills which are required. The second main theme concerns the potentially unstable shift in the labor market has toward a high-level context. The third is about the technical interface of humans and machines, and finally, the fourth understands the German industry as a starting point for global industrial improvements and work proposal changes. Furthermore, socio-technical systems cover the implications of HRM for SCM in three different dimensions: qualification and education (human competences), collaboration and integration of SCM (organizational competences) and data and information management (technical competences).

An original research agenda for further development of the topic. Additionally, the implications of the findings for SCM practitioners are presented.

SCM managers can benefit from the results of this paper by developing adjusted polices for organizational and human aspects. Specially about training programs to improve technology skills and education programs for cyber-human new plataforms.

So far, Industry 4.0, HRM-related topics and implications for SCM have generally been considered separately. This paper elucidates the few important studies on the impacts of Industry 4.0 on human-related topics, such as the labor market, building a research framework using the main contributions highlighted in the literature. An original research agenda is presented, as well as potential implications for SCM.

This paper aims to analyse user interfaces for search and collection visualisation and navigation from a usability perspective. The final aim is to offer repository owners a scientific basis to support their decisions when they have to choose an interface that can really help users to effectively locate and visualise resources over large digital collections.

This HCI study is divided into two parts: perception and usability. The first one analysed three perceptual abilities required to use interfaces: attention, retention of information and understanding. The second one was run on an ad hoc generated collection including more than 40,000 European digital resources collected and classified according to a given branch of knowledge in the Art & Architecture Thesaurus.

Although visual interfaces proved useful for certain tasks related to resource discovery and search, and despite the overall good general user opinion, the authors found it necessary to conduct another thorough study to know more about the target users and the amplitude of the collection, as well as to determine the ideal type of interface to implement. All these factors are important for increasing user acceptance and avoiding unnecessary implementation costs.

This research was run on a relatively small sample size of users from Spain and Latin America, which may not be representative of the general population. In similar studies previous knowledge about usability has been reported to introduce bias in the results, so the authors tried to avoid this when selecting the participants.

There are no previous usability studies for the development and implementation of interfaces in digital learning or cultural repositories. The authors' experience highlights the importance of addressing usability aspects a priori, to prevent users from ceasing to use visual interfaces over time, because they do not perceive any benefit from using them.

Social entrepreneurs (SEs) often face various challenges whereby they rely on the support of others to realize their objectives. In this context, ecosystem thinking is very helpful to understand how various stakeholders can assist SEs. The purpose of this paper is to develop a classification of the different types of support that third parties can provide to SEs.

The authors have developed the arguments in this paper based on a literature review of 258 articles on ecosystem thinking and social entrepreneurship. Articles have been retrieved from the Web of Science database, using as search parameters on the one hand publications in top journals, and on the other articles with more than 60 citations. In addition, the authors have received recommendations for relevant good-quality articles following a snowball procedure.

This paper contributes by distinguishing three support categories for SEs – fuel, hardware and DNA – based on what we know from ecosystem thinking. This paper elaborates on the building blocks of each support category, points at the relevant actors and discusses the interrelatedness across support categories.

The three support categories are developed by building on predominantly ecosystem literature. This study implies that the scalability of SEs’ social impact does not only depend on their strengths but also on how well they are supported.

The three support categories are complementary to the strengths of individual SEs. SEs can therefore start with what they have, and then gradually expand their support structure by surrounding themselves with stakeholders that can assist them with fuel, infrastructure and DNA.

Social enterprise theories have elaborated on the various challenges that SEs face. Lack of resources, lack of staff, lack of professional management, underdeveloped networks and mission drift are seen as the most pressing. Although the relevant literature does rightly point out the indispensable support of others, it does so without differentiating between the kinds of support that can help SEs increase their social impact. This paper offers to remedy this by creating three separate support categories: fuel, hardware and DNA.
