Casado Rigalt, Daniel, 2009: El arqueólogo enamorado. Historia oculta de la arqueología española: de los hallazgos fortuitos a los falsificadores de tesoros. La esfera de los libros, Madrid, 275 pp.

Pyrenae acoge la reseña de una obra divulgativa, que debe ser valorada dentro de ese género. No obstante, su lectura también será útil para cualquier profesional que quiera abrir una cata en el estado de la arqueología peninsular de finales de la primera década del siglo XXI, puesto que la firma un doctor en la materia y no un divulgador procedente de otro campo. El arqueólogo enamorado va precedido de un prólogo escrito con amor por Carmen Rigalt, periodista y madre del autor. Bajo el subtítulo Historia oculta de la arqueología española: de los hallazgos fortuitos a los falsificadores de tesoros, se plantea un proyecto elogiable, que aspira a ofrecer un panorama completo del pasado hispánico, desde la más remota prehistoria a los visigodos, haciendo cuadrar, de forma bastante equilibrada, la amplia geografía peninsular en 14 capítulos y una introducción.

Estacionalidad y productividad del trabajo en un marco tecnológico tradicional: Cataluña Occidental, 1750-1890

El objeto de este estudio es el análisis de los procesos de trabajo en una de las zonas agrarias catalanas más dinámicas durante la última etapa del Antiguo Régimen y primeras décadas de consolidación de la reforma agraria liberal. Las características del proceso de trabajo guardan una clara relación con la estructura agraria de clases. En el marco de la complementaridad de las pequeñas y grandes explotaciones (campesinas, señoriales, ... ) se analiza el trabajo de la tierra, las características de la estacíonaudao -fuertemente condicionada por las necesidades de la trilogía mediterránea- y la exigencia de fuerza de trabajo por hectárea. Respecto a esta última cuestión se establecen, en base a una muestra fiable, los jornales de trabajo por hectólitro de trigo producido.

The First World War and Coal Trade Geography in Latin America and the Caribbean, 1890-1930

This paper aims to illustrate the dynamics of coal trade between Latin America and its main trade partners, i.e., the USA, Great Britain, and Germany, before and after the enormous disruption caused by the First World War. The coal trade was used as an indicator of modernization for Latin American countries, given that oil was at that time of secondary importance. Energy imports have determined the possibilities of each Latin American country in its process of development. Here, we address this question and place special emphasis on supply channels, concluding that the trade link with main suppliers was of key significance. Although this was very clear by the end of the period, the process had started well before the First World War, at least for the majority of LA&C countries. These points are developed through a gravity model applied to the bilateral coal trade. The importance of the market supplier share is addressed through cluster methodologies.

Spermiogenesis and spermatozoon ultrastructure of the dilepidid cestode Molluscotaenia crassiscolex (von Linstow, 1890), an intestinal parasite of the common shrew Sorex araneus

Spermiogenesis in Molluscotaenia crassiscolex begins with the formation of a differentiation zone containing two centrioles. One of the centrioles develops a flagellum directly into the cytoplasmic extension. The nucleus elongates and later migrates along the spermatid body. During advanced stages of spermiogenesis, a periaxonemal sheath appears in the spermatid. Spermiogenesis finishes with the appearance of a single helicoidal crested body at the base of the spermatid and, finally, the narrowing of the ring of arched membranes causes the detachment of the fully formed spermatozoon. The mature spermatozoon of M. crassiscolex exhibits a partially detached crested body in the anterior region of the spermatozoon, one axoneme, twisted cortical microtubules, a periaxonemal sheath, and a spiralled nucleus. The anterior spermatozoon extremity is characterized by the presence of an electron-dense apical cone and a single spiralled crested body, which is attached to the sperm cell in the anterior and posterior areas of region I, whereas in the middle area it is partially detached from the cell. This crested body is described for the first time in cestodes. The posterior extremity of the male gamete exhibits only the disorganizing axoneme. Results are discussed and compared particularly with the available ultrastructural data on dilepidids sensu lato.

Baixem de les tarimes i connectem: recerca en història medieval i innovació docent

We would like to introduce our group of research, [CONTRA TAEDIUM], created by professionals from different fields, that have contributed in this article. Our purpose is to expose our reflections based on our own experiences, not only in research, but also in teaching. We propose new forms of writing history in order to understand the dairy life of the women and men of the past, from birth to death. We would like to point out that interacting all types of sources is essential to understand our history. But, what really makes sense is to bring our students in the historical methodology and involve them in their education. Moreover, it is necessary to design new teaching materials using the new technologies, although it requires team-work and a great, but satisfying, effort
