La avenencia: solución pacífica de conflictos en el Derecho de cristianos y musulmanes hispanos (S. X-XVI)

Las fuentes del Derecho español se han ocupado a lo largo del tiempo, y sin solución de continuidad, de la institución del arbitraje en el marco de la administración de justicia. El arbitraje, avenencia o conciliación son términos que poseen un significado singular en los sistemas u ordenamientos jurídicos que han connotado la Historia del Derecho. El Derecho andalusí se ocupó de la institución del arbitraje por dos razones fundamentales. La primera razón de este interés obedecía a su importancia como medio eficaz y rápido para solventar diferencias o conflictos entre partes. La segunda razón se debía a las particularidades que esta modalidad de resolución presentó respecto a la ortodoxia malekí. Este trabajo analiza los elementos y características del arbitraje y la avenencia con el fin de trazar una visión más completa de la institución, que desde la Edad Media fue medio habitual para la solución de situaciones controvertidas entre cristianos y musulmanes.

El sur también existe: las relaciones migratorias entre las islas Baleares y la Argelia francesa (1830-1962)

La Argelia francesa (1830-1962) constituyó un poderoso polo de atracción para los habitantes de las islas Baleares y del sudeste peninsular. En este artículo se analizan las relaciones migratorias y comerciales entre el archipiélago balear y su por entonces próspero vecino del sur. Además, también se estudian los diferentes exilios que vincularon las dos riberas del Mediterráneo. Para realizar este artículo se han combinado tanto fuentes primarias como la bibliografía existente.

Métodos de máxima verosimilitud en ecología y su aplicación en modelos de vecindad

Los métodos de máxima verosimilitud (MMV) ofrecen un marco alternativo a la estadística frecuentista convencional, alejándose del uso del p-valor para el rechazo de una única hipótesis nula y optando por el uso de las verosimilitudes para evaluar el grado de apoyo en los datos a un conjunto de hipótesis alternativas (o modelos) de interés para el investigador. Estos métodos han sido ampliamente aplicados en ecología en el marco de los modelos de vecindad. Dichos modelos usan una aproximación espacialmente explícita para describir procesos demográficos de plantas o procesos ecosistémicos en función de los atributos de los individuos vecinos. Se trata por tanto de modelos fenomenológicos cuya principal utilidad radica en funcionar como herramientas de síntesis de los múltiples mecanismos por los que las especies pueden interactuar e influenciar su entorno, proporcionando una medida del efecto per cápita de individuos de distintas características (ej. tamaño, especie, rasgos fisiológicos) sobre los procesos de interés. La gran ventaja de aplicar los MMV en el marco de los modelos de vecindad es que permite ajustar y comparar múltiples modelos que usen distintos atributos de los vecinos y/o formas funcionales para seleccionar aquel con mayor soporte empírico. De esta manera, cada modelo funcionará como un “experimento virtual” para responder preguntas relacionadas con la magnitud y extensión espacial de los efectos de distintas especies coexistentes, y extraer conclusiones sobre posibles implicaciones para el funcionamiento de comunidades y ecosistemas. Este trabajo sintetiza las técnicas de implementación de los MMV y los modelos de vecindad en ecología terrestre, resumiendo su uso hasta la fecha y destacando nuevas líneas de aplicación.

Il valore del voto: Italia e Spagna nel dibattito sulla rappresentanza politica liberale (1860-1870)

During the 1860's and 1870's, Spain and Italy experienced a convergence of debates on the significance of political representation in the framework of Liberal State. Spain suffered a political and social crisis, ending with the Revolution of 1868 and the adoption of male universal suffrage in 1878. Its coeval Italy began to build its new Kingdom, anxious about state building, as well as the relevance of electoral processes in the Constitutional scheme. Although members of parliament and essayists of both countries well knew their neighbour's political reality, a dialogue on representation didn't occur. Nonetheless, we believe it is useful to analyse the survey drawn by the Italian publicist in the light of current knowledge of the opinions that prevailed in Spain. What sense did they give to the general election? How did they understand the value of the vote? Who were considered eligible voters? These questions comprise the main subjects of the essay.

An ethnopharmacological and historical analysis of “Dictamnus”, a European traditional herbal medicine

Ethnopharmacological relevance and background: “Dictamnus” was a popular name for a group of medicinal herbaceous plant species of the Rutaceae and Lamiaceae, which since the 4th century have been used for gynaecological problems and other illnesses BCE and still appear in numerous ethnobotanical records. Aims: This research has as four overarching aims: Determining the historical evolution of medical preparations labelled “Dictamnus” and the different factors affecting this long-standing herbal tradition. Deciphering and differentiating those medicinal uses of “Dictamnus” which strictly correspond to Dictamnus (Rutaceae), from those of Origanum dictamnus and other Lamiaceae species. Quantitatively assessing the dependence from herbal books, and pharmaceutical tradition, of modern Dictamnus ethnobotanical records. Determining whether differences between Western and Eastern Europe exist with regards to the Dictamnus albus uses in ethnopharmacology and ethnomedicine. Methods: An exhaustive review of herbals, classical pharmacopoeias, ethnobotanical and ethnopharmacological literature was conducted. Systematic analysis of uses reported which were standardized according to International Classification of Diseases – 10 and multivariate analysis using factorial, hierarchical and neighbour joining methods was undertaken. Results and discussion: The popular concept “Dictamnus” includes Origanum dictamnus L., Ballota pseudodictamnus (L.) Benth. and B. acetabulosa (L.) Benth. (Lamiaceae), as well as Dictamnus albus L. and D. hispanicus Webb ex Willk. (Rutaceae), with 86 different types of uses. Between 1000 and 1700 CE numerous complex preparations with “Dictamnus” were used in the treatment of 35 different pathologies. On biogeographical grounds the widespread D. albus is a far more likely prototypical “Dictamnus” than the Cretan endemic Origanum dictamnus. However both form integral parts of the “Dictamnus” complex. Evidence exists for a sufficiently long and coherent tradition for D. albus and D. hispanicus, use to treat 47 different categories of diseases. Conclusions: This approach is a model for understanding the cultural history of plants and their role as resources for health care. “Dictamnus” shows how transmission of traditional knowledge about materia medica, over 26 centuries, represents remarkable levels of development and innovation. All this lead us to call attention to D. albus and D. hispanicus which are highly promising as potential herbal drug leads. The next steps of research should be to systematically analyse phytochemical, pharmacological and clinical evidence and to develop safety, pharmacology and toxicology profiles of the traditional preparations.

Interpersonal relations and nurses' job satisfaction through knowledge and usage of relational skills

Background/rationale: Many interpersonal labor disputes stem from the lack of communication skills and the relational problems in the interactions between health professionals. Aims/methods: A qualitative study was conducted in a Spanish hospital in order to get to know how the communicative interaction between hospital nurses is like in relation to the nurses' interpersonal interaction and communication skills developed in their working relationships. Twenty-one hospital nurses between 29 and 55 years old, working in different wards, were interviewed. Open-ended interview discourses were transcribed verbatim and analyzed using qualitative content analysis. Results: The following four key themes were analyzed: communication and sender; communication and awareness of who has the problem; non-verbal communication; communication and recipient. Conclusion: The results of this study highlight the need to broaden nurses' relational–communication skills in order to increase job satisfaction.

On the suitability of Prototype Selection methods for kNN classification with distributed data

In the current Information Age, data production and processing demands are ever increasing. This has motivated the appearance of large-scale distributed information. This phenomenon also applies to Pattern Recognition so that classic and common algorithms, such as the k-Nearest Neighbour, are unable to be used. To improve the efficiency of this classifier, Prototype Selection (PS) strategies can be used. Nevertheless, current PS algorithms were not designed to deal with distributed data, and their performance is therefore unknown under these conditions. This work is devoted to carrying out an experimental study on a simulated framework in which PS strategies can be compared under classical conditions as well as those expected in distributed scenarios. Our results report a general behaviour that is degraded as conditions approach to more realistic scenarios. However, our experiments also show that some methods are able to achieve a fairly similar performance to that of the non-distributed scenario. Thus, although there is a clear need for developing specific PS methodologies and algorithms for tackling these situations, those that reported a higher robustness against such conditions may be good candidates from which to start.

Engineer Leandro Badarán’s project to safeguard the fortresses of Alicante in 1794

After the construction of the San Carlos bastion in Alicante in the final decade of the seventeenth century, and the great trench which the English built around the district of San Francisco during their years of dominance in the War of Succession, the waters of the San Blas gully caused serious damage to these fortifications of the city and to the trade buildings of the port. In 1772, the diversion canal was built. It was designed to divert the riverbed of the gully and send the waters directly to the sea. The project had been initially designed by the Engineer General, Jorge Próspero de Verboom in 1721. This unique work of engineering had some defects, principally in the breakwater which prevented the waters from flowing down the former river course. On several occasions, the water returned to its original riverbed due to the weakness of the breakwater, the narrowness of the channel’s bed and its lack of regularisation, causing serious damage to the bastion, the Babel-facing façade, the traders’ warehouses and other buildings. This study describes the project that the military engineer Leandro Badarán carried out in 1794 in order to technically improve this canal and examines his report on the state of the fortifications. Similar works built in Spain are also explained. It also analyses the repeated disputes between the war department and the port throughout these years over finding a technical solution to the problem.

From privatisation to nationalisation: Repsol-YPF, 1999–2012

In April 2012 Argentinean Government nationalized 51% of Repsol shares in YPF. Expropiation of YPF is a new step in a broad list of protectionist and interventionist decisions, such as the nationalization of Aerolíneas Argentinas, nationalization of private pension plans, or the amendments of the Central Bank regulations to make the use of reserves more flexible. Institutions set the rules of the game for citizens and companies, allowing incentives and creating expectations. Nationalization of the above mentioned Argentinean companies has created legal uncertainty bringing a relevant increase in the risk premium as a result. Privatization of YPF and its later nationalization, together with the company shareholder composition, and resulting international disputes will be addressed in this article.
