“When James Boswell returned from a tour of Corsica in 1765 he wrote: ‘It is indeed amazing that an island so considerable, and in which such noble things have been doing, should be so imperfectly known.’ The same might be said today of Puerto Rico.” Thus began Millard Hansen and Henry Wells in the foreword to their 1953 look at Puerto Rico's democratic development. Four decades later, the same could again be said about the island.

This paper describes the level of self‐perceived health (SPH) in immigrant and native populations resident in Madrid and the demographic and socioeconomic factors associated with negative self‐perceived health status, from a gender perspective. A population‐based home survey (2005 Madrid Health Survey) was carried out. Subjects were selected by random sampling of bistage clusters. The study was limited to 5704 adults (16 to 64 years). SPH was considered the dependent variable. The independent variables included migration status, social class, age, sex, marital status, level of education, area of residence, work precariousness, family burden and perception of environmental quality. The association was assessed by odds ratios and their 95% confidence intervals obtained by multivariate logistic regression models disaggregated by gender and migration status. Results showed that poor/fair health status was perceived more by natives and by women. The variables associated with fair/poor SPH in immigrant men were the influence of working conditions perceived as negative and perception of the quality of the environment as poor, and in immigrant women, older age, low educational level and the influence of working conditions perceived as negative. Gender inequalities in self‐perceived health exist, and different factors are associated with immigrant and native populations. The results of the study support the need for a health intervention that would diminish gender inequalities in health, which are more accentuated in immigrants.

Recently, the application of quality management systems (QMS) in educational institutions has become widespread, in an effort to improve diverse processes and results in schools. However, there are very few studies that enable us to confirm whether these QMS bring true changes that are sustainable over time and lead to improvements in these institutions.

This study thus aims to assess the impact of the implementation of ISO:9001 standards on school climate and on the satisfaction of the members of the educational community at 80 Spanish preschools, primary and secondary schools in different autonomous communities.

The analyses performed show conclusive results regarding the impact of ISO:9001 standards on teachers' involvement in improving the school's climate, conflict resolution by the management team and in families' involvement and satisfaction with the school. However, no apparent evidence was found of the impact on relations among teachers, conflict resolution among staff members and the perception of satisfaction by the teachers themselves.

We must bear in mind that the results and conclusions obtained are based on the instrument developed for this study, where it has been the members of the schools themselves who have assessed the changes they have perceived or that have taken place. However, due to the limitation of the instrument, it could be complemented in future research with external evaluations that could complement the results obtained in the present study.

Furthermore, greater impact of the ISO standards was identified in schools from certain regions (Valencia and Andalusia), in state-assisted private schools, in smaller schools and in institutions which have been implementing the QMS for longer periods of time. The management team also perceived a greater improvement in climate than did teachers.

More than 20 songs by Spanish and non-Spanish bands about the Castilian lord and epic hero Rodrigo Díaz de Vivar, El Cid, account for the topicality of the Hispanic Middle Ages in heavy metal. This chapter explores how diversely El Cid is addressed in 10 of these songs, in particular, from the perspectives of reception theory and both the cultural background of the band (Spanish or non-Spanish) and the language in which the lyrics are written (Spanish or English). Through detailed textual analysis and contextualisation, I will examine how, for Spanish (and Spanish-American) bands, El Cid serves the purpose of naturalising the stereotypical heavy-metal medieval knight, thereby functioning as a vindication of Hispanic cultural heritage within what is perceived to be an Anglo-American (and Germanic-Nordic) dominated musical scene. By contrast, non-Spanish bands resort primarily to El Cid to refresh the overused motif of the medieval knight, but sometimes in a more connoted manner as well, in which his iconic value as a Moor-slayer and a defender of the Western white Christian principles is highlighted. Moreover, I will discuss the appropriation and re-appropriation of El Cid by, respectively, non-Spanish and Spanish heavy metal bands, from the point of view of cultural appreciation and appropriation, and Islamophobia.

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 purpose of this paper is to analyse and compare the impact of implementation of ISO 9001:2008 Standards perceived by Management Teams and Teachers in schools in four autonomous communities in Spain.

To assess this impact, the authors used an evaluation instrument made up of 93 items assessing seven major dimensions, whose reliability has been excellent for the full scale (Cronbach’s α = 0.987) and dimensions (α > 0.93). The authors conducted descriptive and differential analyses (ANOVA and t-test for independent samples) of the assessments by professional position (managers and teachers) and other variables (size and type of school, years of implantation, etc.). A factorial analysis of variance was conducted to analyse the interaction effect between these variables in each of the evaluated dimensions.

The most significant results show a high impact on the dimension management, medium on communication, learning process and external relations and low impact on climate, support and recognition and satisfaction. Likewise, the authors found that members of the Management Teams valued the impact that ISO 9001:2008 Standards have had on all dimensions at a higher level, except for external relations, where no significant differences between Teachers and Management Team members were found.

The study makes it possible to conclude that in general terms, the members of the Management Team of the schools perceive a higher impact of the implementation of ISO 9001:2008 Standards than teacher do in the different dimensions evaluated.

The specialised literature shows the lack of studies related to the impact that the implementation of quality management systems has on organisations. Specifically, this study provides conclusions to the scientific and professional community with objective evidence of the impact ISO 9001:2008 implementation has had on schools, through an indirect system of perceptions of the education community of the changes, which according to them had taken place as a result of implementation. Thus, this study contributes to the development of a new body of knowledge by evaluating this impact.

The purpose of this paper is to analyze how sustainability was operationalized in the Spanish universities through plans and actions that contribute actively to the achievement of the sustainable development goals (SDGs).

A systematic search and content analysis served to examine information available on websites belonging to the 76 universities listed in the Conference of Rectors of the Spanish Universities (CRUE).

The participation of Spanish universities on initiatives focused on sustainability is very limited, highlighting the negligible role of private institutions in which topics like sustainability and the 2030 Agenda/SDGs were scarcely addressed.

The study outlines the actual extent of the inclusion of sustainability in particular co-curricular actions toward the SDGs in the CRUE. The findings enable to define a long-term sustainability road map for the Spanish university system.

A growing number of schools are now implementing quality management systems (QMS). As a result, studies are being conducted to assess the educational benefits of these systems and their capacity to identify areas for improvement in school processes and performance. The purpose the present study is to assess the impact of ISO:9001 implementation on teaching-learning processes in the classroom, and in schools with at least three years’ experience of applying this standard.

To this end, a questionnaire was administered to a final sample of 2,185 subjects from 80 pre-school, primary and secondary education schools in the regions of Madrid, Castile and León, Andalusia and Valencia (Spain).

The results show that ISO:9001 implementation yielded a higher than average impact on teaching-learning processes. Specifically, improvements were observed in the subdomains of tutorials, evaluation and classroom teaching methodologies as a result of implementing this QMS.

This impact was higher in state-subsidized private schools in Valencia and Andalusia with over nine years’ experience of ISO:9001 in schools with internal funding plans and in those with fewer than 29 teachers on the staff.

In this survey we present (after an Introduction) a guide to the major doctrinal trends of Spanish accounting of the period, classified in various categories: different views of the scientific nature of accounting, dominant theories, purposes of accounting, special areas, views on classification and on the recording of transactions, views on valuation and depreciation, cost accounting, inflationary issues, auditing, accounting terminology, historical concerns, and the practical orientation of publications. A separate section offers further details about prominent Spanish scholars; it is followed by the conclusion. The latter indicates that during the period under investigation, Spanish accountants contributed little to novel accounting thought, but strongly relied on French and Italian doctrines, though neglecting German ideas. Despite of this, Spanish accountants were aware of many theoretical and instrumental novelties of the day, and applied them without substantial delay to their own environment.

This article aims to study a model of flame propagation in a nonhomogeneous medium with a p-Laplacian operator. The intention with such operator is to model the effects of slow and fast diffusion, that can appear in a nonhomogeneous media, depending on the pressure driven conditions. In addition, the authors introduce a general form in the reaction term, that introduces the flame chemical kinetics.

To introduce the governing equations, the authors depart from previously reported models in flame propagation, but the authors consider a new modeling approach based on a p-Laplacian operator.

The authors provide evidences of regularity and uniqueness of solutions. Afterward, the authors introduce profiles of stationary solutions based on the definition of a Hamiltonian for the newly discussed model. Eventually, the authors obtain exponential profiles solutions with the help of a scaling, that transforms the model into a nonlinear Hamilton–Jacobi equation.

The new model has not been previously reported in the literature. The authors consider that the mathematical properties of a p-laplacian (in particular the property known as finite propagation) is of inherent interest to model pressure drive flames with slow or fast diffusion. Indeed, the authors’ approach has the value of providing an operator that can fit better to model flame propagation. In addition, the authors introduce a general form of chemical kinetics, to make the authors’ model further general.
