Two transmission line meshes to simulate electromagnetic waves in the Earth's atmosphere are developed, one with the link transmission lines connected in parallel and the other with connections in series.

The equations describing propagation of waves through these parallel or series meshes are equivalent to the Maxwell equations for TE^r or TM^r modes in a spherical cavity with lossy dielectric material between the external conducting surfaces, respectively.

The transmission line meshes are used for a numerical study of the natural electromagnetic noise due to lightning discharges in the Earth‐ionosphere cavity.

The numerical algorithm finds values for Schumann resonances very close to the experimental ones, which allows us to affirm that this methodology is a valid numerical tool for predicting these resonances on other planets or moons as well.

The purpose of this paper is to analyze the circumstances that have conditioned the development of education in Spain from the enlightenment to the present day.

Multidisciplinary scientific approach that combines the interpretation of the legal texts with the revision of the doctrinal and theoretical contributions made on the issue.

From the beginning of the nineteenth century, the history of education in Spain has been marked by constant fluctuations between the reactionary instincts, principally maintained by the Catholic Church and the conservative social classes, and the progressive experiments, driven by the enlightened and the liberals first, and the republicans and the socialists later. As a consequence of that, the fight for finishing with illiteracy and guaranteeing universal schooling underwent permanent advances and retreats, preventing from an effective modernization of the Spanish educative system. On the one hand, renewal projects promoted by teachers and pedagogues were inevitably criticized by the ecclesiastical hierarchy, obsessed with the idea of preserving the influence of religion on the schools. On the other hand, successive governments were weak in implementing an educational policy which could place Spain at the level of the other European and occidental nations.

At the dawn of the twenty-first century, although the country has overcome a good part of its centuries-old backwardness, increasing economic difficulties and old ideological splits keep hampering the quality of teaching, gripped by neoliberal policies which undermine the right to education for all. The reading of this paper offers various historical clues to understand this process.

The purpose of this paper is to analyse the evolution and characteristics of health education in schools in Spain during the dictatorship of General Franco (1939-1975).

The analysis of two kinds of sources has been performed. First, the reports from international organizations on health education in schools published in the 1950s and 1960s. Second, journals, books and official documents published by public health and education organizations in Franco’s Spain.

Health education in schools evolved in three stages under Franco’s dictatorship. In the first stage (1939-1953), Spanish schools maintained an outdated “school health” approach in the teaching programmes. In the second stage (1953-1965), the agreements with the USA in 1953 ended Spanish isolation, and the regime sought to follow the recommendations of international organizations. Efforts were made to “import” the WHO/UNESCO version of health education in schools but it failed to materialize. A programme that sought to enhance citizen participation and to acknowledge their idiosyncrasies was unlikely to prosper in a dictatorship. However, the less threatening food and nutrition education programme, encouraged by the FAO/UNICEF, did succeed. In the last stage (1965-1975), the Spanish education system entered a period of modernization in which the contents and methods of health education in schools were reformed in order to introduce the less conflictive aspects of the international recommendations.

The paper highlights the tensions between the aspirations to follow international programmes and the recommendations on health education in schools and the difficulties of implementing such schemes under a dictatorship.

The purpose of this study is to propose a comprehensive efficiency evaluation approach to measure the efficiency of the retailers and to determine the relative importance of a wide variety of apparel retail-specific factors that support efficiency.

The first stage of the proposed approach is the measurement of the relative efficiency of the apparel retailers by using data envelopment analysis (DEA) for identifying the best practice frontier and determination of the improvement ratios. The second stage is the prioritization of the factors that are important in the apparel retail efficiency using analytical hierarchy process (AHP).

The findings of the study revealed that the quantitative criteria to be considered for efficiency through input minimization and output maximization were “number of employees” and “profit before tax,” respectively, however, focusing on output maximization was found to be more critical. In addition, it was seen that the most important qualitative components of efficiency were satisfied customers, qualified staff and branding.

The managerial actors in the apparel retail industry can be alerted for new strategic actions to adopt best practices or take precautions for future inefficiencies with the help of the results obtained. The customized hierarchical structure allows determining the priority areas that need to be focused on for increasing the performance of apparel retailers.

In this study, DEA and AHP were combined to build a comprehensive efficiency evaluation approach in the apparel retail industry for the first time in the literature. Thus, both qualitative and quantitative variables that are important in apparel retail efficiency were put forward and evaluated. The originality of the hierarchical structure in AHP was its customization to the apparel retail industry.
