Fused deposition modeling (FDM) is booming as a manufacturing technique in several industrial fields because of its ease of use, the simple-to-meet requirements for its machinery and the possibility to manufacture individual specimens cost-effectively. However, there are still large variations in the mechanical properties of the prints dependent on the process parameters, and there are many discrepancies in the literature as to which are the optimal parameters.

In this paper, thermal evolution of the printed specimens is set as the main focus and some phenomena that affect this evolution are explored to differentiate their effects on the mechanical properties in FDM. Interlayer waiting times, the thermal effects of the position of the extruder relative to the specimens and the printing layout are assessed. Thermal measurements are acquired during deposition and tensile tests are performed on the specimens, correlating the mechanical behavior with the thermal evolution during printing.

Additional waiting times do not present significant differences in the prints. Thermal stabilization of the material is observed to be faster than whole layer deposition. The layout is seen to affect the thermal gradients in the printed specimens and increase the fragility. Strain at breakage variations up to 64% are found depending on the layout.

This study opens new research and technological discussions on the optimal settings for the manufacturing of high-performance mechanical components with FDM through the study of the thermal gradients generated in the printed specimens.

The objective of this study is to review the main studies of social entrepreneurship (SE) in Latin America, to categorize them into four categories. To accomplish this, a bibliometric literature review is carried out based on data from the Web of Science database, to locate the Latin American collection of studies. In this way, the main studies are described and grouped, following a qualitative scheme that allows to substantiate the main findings of the Latin authors. Consequently, the progress made in the literature of the SE for Latin America is corroborated, by visualizing that the SE turns out to be a forceful fact to manage well-being, but that it is faced with an inconsistent development.

Based on the human resource (HR) and supply chain integration (SCI) literature, this paper aims to argue that high-involvement human resource practices (HIHRP) work as a complementary capability for SCI, and thus, HIHRP moderates the relationship between SCI and firm productivity. This moderating role is analyzed through the following HIHRP dimensions, namely, ability-enhancing, motivation-enhancing and opportunity-enhancing practices framework.

Using empirical data collected from a survey of the agri-food sector (horticultural firms of southern Spain), the moderating effects of HIHRP on the relationship between supply chain external integrations (with customers and suppliers) and productivity are examined. Hierarchical regression analysis is used to test the proposed hypotheses.

The results support that HIHRP has a moderating effect on the SCI/productivity relationship. However, these results are only significant in the case of supplier integration.

This study analyzes HIHRP as a complementary asset in the context of SCI and makes both theoretical and managerial contributions to the SCI literature by empirically analyzing the role of HR practices in enhancing the relationship between SCI and performance.

The object of this research is the reconstruction of the existing legal response by European Union states to the phenomenon of immigration. It seeks to analyse the process of conferral of protection.

One main dimension is selected and discussed: the case law of the national courts. The study focuses on the legal status of immigrants resulting from the intervention of these national courts.

The research shows that although the courts have conferred an increasing protection on immigrants, this has not challenged the fundamental principle of the sovereignty of the states to decide, according to their discretionary prerogatives, which immigrants are allowed to enter and stay in their territories. Notwithstanding the differences in the general constitutional and legal structures, the research also shows that the courts of the three countries considered – France, Germany and Spain – have progressively moved towards converging solutions in protecting immigrants.

The research contributes to a better understanding of the different legal orders analysed.

This ethnographic study explores how local and global forces influence a unique set of self-employed people in Havana’s tourism industry – dance instructors – and how these circumstances drive the strategies and rationalities they use to navigate socioeconomic transformations. Cuba’s recent history of economic crises, the decline in welfare assistance, and an array of market-driven economic reforms have driven many Cubans to search for incomes in Havana’s lucrative tourism industry. Global circulations of people, wealth, and ideas shape the opportunities Cubans find in this type of work. Furthermore, strict state policies and regulations, in conjunction with underlying systems of oppression, hinder and constrain Cubans who work in tourism-based ventures. Building on theories of neoliberalism and tourism, we discuss how Cuban dance instructors develop professional skills, standardize their activities, and address global consumer desires/demands while simultaneously drawing from collectivized social norms cultivated under Cuban socialism. These hybridized formal/informal business tactics reveal how self-employed Cubans are positioned between socialist configurations and the capital-driven tourism industry. These innovative socioeconomic logics are also critical in understanding how people living in centrally planned economies, some of which are socially marginalized because of patterns of inequality, gain access to and participate with contemporary modalities of the global economy.

The purpose of this paper is to identify those resources and capabilities that enable national award-winning organizations to generate value to their stakeholders and provide evidence to institutions holding business excellence model (BEM)-based programs of how dynamic capabilities theory can enhance excellence models.

Qualitative research based on systematic review and content analysis.

Empirical evidence supports that BEMs should consider the resource-based view and dynamic capabilities perspective as a basis for their continuous improvement. These theoretical perspectives consider resources and capabilities for the successful execution of the strategic plan and for a faster response to environmental changes through dynamic capabilities.

The study is based on a systematic review and content analysis of evidence submitted by three national quality awards from Europe, Singapore and Mexico. This research should be extended to other national quality award companies, and their customers’ and suppliers’ insights should be considered.

Regardless of corporate sector, organizations must recognize that visionary leadership is vital to their management models; a strategic plan and competent staff to execute the model are also of great importance. In addition, institutions holding BEM-based programs should evaluate incorporating dimensions related to dynamic capabilities and emphasize those strongly related to national culture.

Few studies in the BEMs literature have conducted resources and capabilities analysis from a multi-country perspective.

This study aims to determine whether the communication of Universities in Madrid (Spain) on social networks through their official channels has caused positive results in students’ perceptions of their trust in university institutions during the first semester of the 2020–2021 term and to measure whether the implementation of happiness management strategies in the communication within university governance affected students’ happiness levels, as well as on the recognition of their belonging to the university.

With an exploratory-correlational approach and a quantitative study, this study conducted a statistical-descriptive analysis based on the premise of a general linear regression model with correlations between the variables, using a data collection instrument, whose construct and content validity was previously assessed by experts, which was answered by 564 students of the Degrees in Communication and Marketing from the Complutense University of Madrid, University of La Laguna, and ESERP Business and Law School. The Kaiser-Meyer-Olkin test and Bartlett’s test of sphericity were implemented to analyze the correlation between variables; Cronbach’s alpha coefficient and Pearson and Spearman’s coefficients were also used.

Those students who used social networks to receive news from university institutions about the COVID-19 pandemic deem these channels official, sound and credible. Similarly, the use of official information from university institutions on social networks increases students’ happiness levels.

To the best of the authors’ knowledge, this is one of the first studies aiming to provide scientific evidence of the relationship between happiness management and university governance. This research’s practical implications lead to attributing added value to these types of means for the university governance that seeks students’ happiness.

The purpose of this paper is to determine the presence of palm oil in food products on sale, and to study and compare consumers’ opinions about this oil type in Spain (importing country) and Peru (producing country).

Recent news published in both countries, which could influence consumer perceptions, were analysed. A study on the labelling of foodstuffs in Spain was carried out, as was a survey with Spanish and Peruvian consumers.

Palm oil was found in a large number of products and in a wide range of foods, especially those from the bakery sector. The percentages of saturated fats varied substantially within the same product type. Spanish consumers showed much more interest in the labelling and information on nutritional properties, especially energy values, saturated fats and sugars, while Peruvians focused more on energy values, and protein, vitamin and mineral contents. In Spain, palm oil was considered the worst quality fat/oil and had a clearly negative effect on both health and the environment. In Peru, palm oil was neither perceived by the majority of respondents as low quality oil nor associated with negative health effects. However, they were aware of the environmental problems that could result from its production.

These results confirm that the food industry should make efforts to reduce or replace palm oil in foods, mainly in Spain, as most consumers believe that palm oil negatively affects their health and the environment.

Directing schools of high complexity in disadvantaged social contexts with high rates of emigration requires skills for emotional leadership. Directors with self-managing capacities are needed to manage their own emotions. They also need to mobilise people (teachers, students and families) by focussing on their feelings of satisfaction, identification with the group, belonging, joy, success, unity and cohesion.

The content of this chapter presents the study of the emotional management of directors who perform their work in two highly complex schools in Catalonia, Spain. The views of these directors as well as teachers and families examine: (1) the construction of their professional identity, (2) their social and ethical commitment to the community, (3) the orientation towards the values of social justice and (4) their emotional leadership practices focussed on personal attention towards all of the actors in the school community.

The chapter concludes with 10 suggestions that can be useful to improve the professional practice of school directors. These should also be taken into account when designing and implementing initial and ongoing training programmes for school leaders and to inspire ideas for future research.
