The evaluation of novel materials such as the acrylonitrile styrene acrylate (ASA) for tribological and mechanical conditions can provide a structural protection against the environmental and wear effects that results in the long-term integrity of the 3 D printed parts. Results of the experimental stage are intended to identify the influence of the printing conditions on the functional characteristics of ASA parts that results in variations of the friction coefficient, wear rate and tensile response. In addition, this study aims to highlight the relevance of printing parameters to avoid the use of chemical post-processing stages, increasing the performance and sustainability of the process.

In this research, an evaluation of the influence of printing parameters of layer thickness and temperature on the mechanical and tribological response have been carried out for ASA specimens manufactured by fused filament fabrication technology. For this purpose, a range of three different values of thickness of fused layer and three different printing temperatures were combined in the manufacturing process of tests samples. Mechanical behavior of the printed parts was evaluated by standard tensile tests, and friction forces were measured by pin-on-disk tribological tests against steel spheres.

Higher layer thickness of the printed parts shows lower resistance to tribological wear effects; in terms of friction coefficient and wear rate, this type of parts also presents lower tensile strength. It has been detected that mechanical and tribological behavior is highly related to the micro-geometrical characteristics of the printed surfaces, which can be controlled by the manufacturing parameters. Under this consideration, a reduction in the coefficient of friction near to 65% in the average value was obtained through the variation of the layer thickness of printed surfaces.

This research aims to fill a gap in the scientific literature about the use of specific additive manufacturing materials under dynamic contact. This paper is mainly focused on the influence of the manufacturing parameters on the tribological and mechanical behavior of a weather resistant polymer (ASA).

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.

This paper analyses the strategies designed by Franco´s dictatorship to address the “problem” of children with physical disabilities, focusing on the relevance given to vocational training.

The paper draws mainly on official documents, reports from international organisations, and Spanish experts' papers.

Francoism turned labour into one of the key pillars of its national project and included vocational training in the different stages of school life. From the mid-1950s, vocational training also became a key factor for the dictatorship's strategy towards disability. Following the recommendations issued by international agencies, Francoism began to adopt different measures towards the rehabilitation of children with disabilities. One of them was the creation, in 1959, of a special unit for adolescents within the National Institute for the Rehabilitation of Invalids. In addition to medical treatment, this unit provided children with education and vocational training.

The value of this paper lies in the fact that the topic it analyses has been little studied. Until now no attention has been given to the special unit for adolescents, despite it being a very interesting example of the medical model of disability and its contradictions. During their stay at the unit children were promised greater autonomy and independence, but their lives also became medicalised and they were forced to collaborate with experts.

The purpose of this paper is to investigate the unexplored part of the historical evolution of travel agencies in Spain, from the end of the 20th century to the 21st century. When examining promotion strategies, the study focuses on the change in marketing and public relations strategies based on the incorporation of information and communication technologies and, in particular, the use of the internet.

This study draws on a qualitative analysis of the different strategies used by traditional agencies and online agencies in Spain from the mid-19th century to the present. This analysis shows how traditional communication strategies survived at the beginning of the 21st century, together with other more innovative ones, while some disappeared, being eliminated by the new online travel agencies, which created a particular conception of marketing and communication. This paper is divided into the following parts: the introduction; the beginnings of travel agency promotion in the 20th century; the evolution of promotion in travel agencies since the late 20th century; communication innovation at the beginning of the 21st century; online travel agencies; and conclusions.

This study shows that although online agencies did not manage to position themselves with a large turnover, they generated advantages and sharpened their imagination to create a new, more economical advertising model, eliminating the costs of public relations and advertising campaigns. In addition, they allowed clients to have greater independence when making their reservations, while enabling them to monitor the tastes of potential and real clients and add blogs so that consumers could express their degree of satisfaction with the product or services provided by the agency.

The focus of attention is the travel agency sector in Spain and, more specifically, communication. Studies on travel agencies and their marketing have been very scarce and partial, impeding professionals in the tourism sector from having a broad vision to direct their promotional and public relations actions. The originality of this article lies in its making a comparison between two different visions of tourism marketing and, specifically, of travel agencies, that is, the traditional vision and the innovative one. It thus helps all professionals in the sector to value and improve their marketing and communication strategies.

This article focuses on the study of the shaping of pedagogy as a discipline in Spain prior to the Civil War. Its aim is to identify those elements that helped pedagogy become constituted as a distinct field of knowledge that could offer rigorous insight into the world of education.

The article uses the framework proposed by Rita Hofstetter and Bernard Schneuwly for the shaping of a disciplinary field. Finally, it briefly examines the process of professionalization, using the approach advocated by the sociologist Elliott Freidson.

The analysis carried out concludes that at the outbreak of the Civil War in 1936 the process of professionalization and consolidation of pedagogy as a discipline had been completed in Spain.

The article presents the originality of reinterpreting the elements offered by Spanish history of education in the light of an international theoretical framework. This allows a new understanding of the process of constitution of pedagogy as a disciplinary field while offering the international public a case study according to international standards.

This paper aims to provide an assessment of tourism promotion in tourist destinations and airports (TPTDs) and to organize and classify the literature on tourism promotion, with the aim of staging the importance of this topic and encouraging future research in the projection of tourism and marketing sectors.

The paper uses the Social Sciences Citation Index (SSCI) database to analyze the bibliometric in TPTDs topic from 2000 to 2021. Additionally, the paper also uses the visualization of similarities (VOS) viewer software to map graphically the bibliographic material. The graphical analysis uses bibliographic coupling, co-citation, citation and co-occurrence of keywords.

This study provides an amended new definition of tourism promotion, which is the efficient management of a destination’s resources and strategic plans by destination marketing organizations (DMOs) to adapt the tourism supply to market trends and will empower tourists to visit such destinations. Furthermore, results also show a new paradigm applied to TPTDs topic and classified in five first-order research streams. Digital and mobile marketing, infrastructure, branding, quality, accessibility and information factors about a specific destination which are mostly demanded by tourists are considered as an important means of promotion for the tourism industry.

The contribution of this study is important to identify new challenges and opportunities for researchers, DMOs, airport and airlines operators and stakeholders, as disentangling existing contradictions and applying new theoretical framework to make better future decisions by researchers and organizations to provide higher quality to new research in the context of the TPTDs.

This study provides a new look at the late 19th-century university issue in Spain. Loss of self-government among universities and the state’s centralization brought a conflict between science and religion to the fore in the process of the secularization of knowledge.

We first delve into the anti-Darwinian framework associated with the scientific professionalization process, focusing on the case of the jurist Antonio Hernández Fajarnés (1851–1909). Secondly, we study the idea of the university that emerged from the Ateneo de Madrid, analyzing key speeches from the jurist Francisco Fernández de Henestrosa (1855–s.d.) given in 1887/88 and from the pharmacist José Rodríguez Carracido (1856–1928).

The study concludes that the Restoration Era in Spain was characterized by a generalized desire – shared by neo-Scholastics, conservatives and liberal rationalists – to improve the public university system. In this context, French influence was no doubt decisive; however, the Humboldtian university idea had already begun to have notable influence.

This article analyzes sources yet unknown to international research, such as the Ateneo de Madrid debates and Spanish university rectors’ inaugural speeches. It opens up a critical examination of the so-called displacement of educational principles in Spain toward a state-centered system of doctrinal moderantismo as opposed to the nation-centered system of the Cádiz liberalism. At the same time, it identifies key pockets of resistance relative to Spanish university transformation toward increased methodological secularization.

Entrepreneurship is presented as a vehicle for innovation and social development. Given the importance of entrepreneurship, the objective of this study was to analyze the psychological and sociological dimensions by determining the factors that explain individual perceptions and cultural support for entrepreneurship.

Using Global Entrepreneurship Monitor (GEM) data obtained from the Adult Population Survey (APS) (N = 2,500) in the region of Andalusia (Spain), a quantitative analysis was carried out, specifically a multivariate analysis based on four-stage linear regressions.

The variables examined do not explain the psychological and sociological dimensions to the same extent. The results highlight the existence of cultural homogeneity between provinces, the importance of sociodemographic variables and the influence of the entrepreneurial expectations and experiences of the population, especially in shaping individual perceptions towards entrepreneurship.

The replication of the study at the national and international levels is proposed in order to delve deeper into the cultural differences that condition entrepreneurship. Including new variables associated with entrepreneurial human capital could also be of interest.

The results can help to improve the design and implementation of policies and programs aimed at fostering entrepreneurship through the promotion of favorable individual perceptions and entrepreneurial culture.

The originality of this study is the consideration of individual perceptions and cultural support for entrepreneurship as dependent variables, since they are normally incorporated as explanatory factors. The results contribute to the advancement of knowledge of the entrepreneurial phenomenon through two approaches, psychological and sociological.

El emprendimiento se presenta como vehículo de innovación y desarrollo social. Dada la importancia del fenómeno, el objetivo de esta investigación es analizar las dimensiones psicológica y sociológica del emprendimiento a través de los factores que explican las percepciones individuales y la cultura de apoyo al emprendimiento.

A partir de datos GEM obtenidos mediante la Encuesta de Población Adulta (N = 2,500) en Andalucía (España), se desarrolla una metodología cuantitativa, concretamente un análisis multivariante basado en regresiones lineales de cuatro etapas.

Las variables consideradas no explican en la misma medida la dimensión psicológica y la sociológica. Se evidencia la existencia de homogeneidad cultural interprovincial, la importancia de las variables sociodemográficas y la influencia de las expectativas y las experiencias vinculadas al emprendimiento, especialmente en la formación de percepciones individuales.

Se propone la réplica del estudio a nivel nacional e internacional para ahondar en las diferencias culturales que condicionan la creación empresarial. Se considera interesante incluir nuevas variables asociadas con el capital humano emprendedor.

Mejora del diseño y la implementación de políticas y programas dirigidos a potenciar el emprendimiento, a través del fomento de las percepciones individuales favorables y la cultura emprendedora.

La originalidad reside en la consideración de las percepciones individuales y la cultura de apoyo al emprendimiento como variables dependientes, ya que normalmente se incorporan como factores explicativos. Se contribuye al avance del conocimiento sobre el fenómeno emprendedor a través de dos enfoques, el psicológico y el sociológico.

In this paper we analyse the effect on unconditional conservatism of the mandatory adoption of International Financial Reporting Standards (IFRS) by the European listed firms in January 2005. Under the hypothesis that accounting regulation influences the accounting conservatism, we use a non-market-based measure of unconditional conservatism – the accrual-based measure proposed by Givoly and Hayn (2000) – to test this effect, controlling for the other determinants of the unconditional conservatism found in the accounting literature.

We use a panel data of 10 years and 96 non-financial listed firms in the Spanish stock market in which the differences between local GAAP and IFRS are more important. A pre-estimation analysis of the data reveals that GLS with random effects is the correct estimation procedure. However, to try to deal with the likely endogeneity in the set of variables, the authors perform an estimate with a dynamic estimator for panels with few periods and many individuals where the independent variables are not strictly exogenous.

As expected, results show evidence that support a significant reduction on the unconditional conservatism of firms in the sample due to the adoption of IFRS. This evidence is relevant to equity market, debt market and corporate governance users of the financial information, and also for the policymakers who can assess the effects of their mandate.

Results shown in this paper have all the limitations of system-, country-, sample- and event-specific studies but, along with many others drawn in alternative contexts, may help to correctly understand both the time-evolution and cross-sectional country differences of firms’ unconditional conservatism.

The study represents the first analysis of the effect of the adoption of IFRS on unconditional conservatism of the European listed companies using a non-market accrual-based measure. Results are not influenced by the dynamics of the stock market and, by comparison, allow us to analyse this influence in results provided by using market-based measures of the unconditional accounting conservatism provided by previous literature.
