Ungulate vehicle collisions (UVC) provoke serious damage, including human casualties, and a large number of measures have been developed around the world to avoid collisions. We analyse the main factors involved in UVC in a road network built in the absence of ungulates, where mitigation structures to avoid UVC were not adequately considered. Ungulate population greatly increased during the last two decades and now Roe Deer and Wild Boars are widely distributed over the study area, but even after this increase, the road network was not adapted to avoid UVC. A total of 235 Roe Deer (RDVC) and 153 Wild Boar vehicle collisions (WBVC) were recorded between January 2008 and December 2011. We randomly selected 289 sample points (87 RDVC, 60 WBVC and 142 controls) separated by at least 500 metres from the next closest point and measured 19 variables that could potentially influence the vehicle collisions. We detected variations in the frequency of RDVC on a monthly basis, and WBVC was higher at weekends but no significant differences were detected on a monthly basis. UVC were more likely to occur at locations where sinuosity of the road, velocity, surface of shrub and deciduous forest area were greater, the presence of fences entered with positive relationship and distance to the nearest building was less. RDVC were more likely to occur at locations where timber forest area increased and distance to the nearest building decreased and WBVC was related to open fields cover and also to the presence of fences. Sinuosity and velocity entered in both cases as significant factors. Major roads, in which the traffic volume is greater and faster, caused more accidents with ungulates than secondary roads. Nowadays, the high frequency of ungulate road-kills deserves a new strategy in order to adapt infrastructure and adopt mitigation measures.

In this article, we employed the induced magnetic field method to show that the Al2X6 (X = F, Cl, Br, I) clusters cannot be classified as aromatic systems. Interestingly, even nucleus independent chemical shift (NICS) reveals the same conclusion when analyzed in greater detail, showing that a superficial analysis of this index can easily lead to incorrect interpretations. In view of the fact that the NICS index is extensively used by computational and theoretically oriented experimental chemists, this is an important warning against superficial analyses, as it can lead to erroneous chemical interpretation.

Espacio de Juan Ramón Jiménez, «uno de los monumentos de la conciencia poética moderna» según Octavio Paz, es un largo poema unitario en tres fragmentos con una historia redaccional espaciada, provisional y compleja. La composición se fue gestando, con una misma «pulsión» (la conciencia de inmensidad espacio-temporal y eternidad), a partir de fragmentos de poemas que el poeta fue publicando en diversas revistas y diarios a lo largo de más de diez años. En este artículo, además de revisarse el proceso de composición (paralelo al poema en prosa Tiempo), la historia editorial, la recepción y la bibliografía de Espacio, se lo adscribe a la tradición del «poema extenso moderno» y a su método compositivo.

Resumen: Decía Octavio Paz que Espacio de Juan Ramón Jiménez era "un monumento de la conciencia poética contemporánea". Ciertamente, este poema largo rebasa gran parte de la tradición poética española del siglo xx y universaliza nuestra poesía conectándola con las corrientes literarias modernas. Pero la maravilla de Espacio es además la de ser un texto que no se acaba nunca y enriquece su misterio en cada lectura forjando nuevas líneas de interpretación. En este estudio pretendemos definir esas líneas hermenéuticas distinguiendo entre "motivos" (mar, mujer, árbol, pájaro, perro…), "asunto" (lo anecdótico del poema) y "temas" (elementos recurrentes como tiempo-espacio, dios, conciencia y amor), que gravitan en torno a otro tema central: la conciencia como conocimiento individual de uno mismo.Palabras clave : Espacio; Juan Ramón Jiménez; poema extenso; tiempo; dios; conciencia.Abstract: Octavio Paz once wrote that Juan Ramon Jimenez's poem Espacio was "a monument of contemporary poetic consciousness". This long poem certainly goes far beyond most of the Spanish poetry written in the 20th century and universalizes the Spanish poetic tradition by putting it into contact with modern literary trends. But if Espacio is so outstanding, it is because it is a poem of inexhaustible mystery, with the result that each rereading forges new lines of interpretation. The present study attempts to define these hermeneutical lines, distinguishing between the motifs (the sea, the woman, the tree, the bird, the dog…), the subject (the anecdotes in the poem) and the themes (such recurring concerns as time-space, god, consciousness and love, which all gravitate around the central theme of consciousness, seen as individual self-knowledge).
