Con la ayuda de algunos ejemplos, se estudia el comportamiento de los sintáxones en los límites corológicos de las unidades fitosociológicas superiores; se muestra que, a medida que nos alejamos de su centro de gravedad, esas unidades pierden poco a poco sus especies y que, en sus límites corológicos, no quedan más especies características de unidades superiores para definir las comunidades. Se evocan entonces algunas consecuencias de esas observaciones: noción de combinación específica original, interpretación fitosociológica de los sintáxones, nomenclatura fitosociológica.

Several landforms found in the fold-and-thrust belt area of Central Precordillera, Pre-Andes of Argentina, which were often associated with tectonic efforts, are in fact related to non-tectonic processes or gravitational superficial structures. These second-order structures, interpreted as gravitational collapse structures, have developed in the western flank of sierras de La Dehesa and Talacasto. These include rock-slides, rock falls, wrinkle folds, slip sheets and flaps, among others; which together constitute a monoclinal fold dipping between 30º and 60º to the west. Gravity collapse structures are parallel to the regional strike of the Sierra de la Dehesa and are placed in Ordovician limestones and dolomites. Their sloping towards the west, the presence of bed planes, fractures and joints; and the lithology (limestone interbedded with incompetent argillaceous banks) would have favored their occurrence. Movement of the detached structures has been controlled by lithology characteristics, as well as by bedding and joints. Detachment and initial transport of gravity collapse structures and rockslides in the western flank of the Sierra de la Dehesa were tightly controlled by three structural elements: 1) sliding surfaces developed on parallel bedded strata when dipping >30° in the slope direction; 2) Joint’s sets constitute lateral and transverse traction cracks which release extensional stresses and 3) Discontinuities fragmenting sliding surfaces.  Some other factors that could be characterized as local (lithology, structure and topography) and as regional (high seismic activity and possibly wetter conditions during the postglacial period) were determining in favoring the steady loss of the western mountain side in the easternmost foothills of Central Precordillera.

The role of the hero is changing, slightly irregular, but it’s purpose is constant. The line that separates good from evil is frequently so thin that sometimes the main hero can act in a negative way, casting doubts about his own nature in the pursuit of good. This paper aims to inquire into the character’s heroic condition showing two variations of this archetype in the context of postmodern cinema: the “clear hero”, and the “dark hero”. The former keeps the most traditional values of the hero, while the latter provides a dimension which distinguishes it from the previous one: his experience executing evil as a part of his process to heroici­ty. Postmodernity implies an ambivalence in the character’s identity which can be comparable to the hero’s role, and to his way of making good. The “clear hero” does not imply negative features in the active nature of the hero, whilst the “dark hero” does include them. Through the protagonists of Gladiator (Scott, 2000) and Batman Begins (Nolan, 2005) are offered both heroic perspectives based on a selection of their principal ac­tions which have been subjected to analysis according to some parameters: behavior, implication, and cause. The decisive action will also be signalized, according to the narration’s teleonomy in reason of the favorable or unfavorable sense for the hero. Finally, each character will be observed from its archetype. By analyzing their actions from these perspectives, we observe the clear hero and the dark hero as affordable categories for the heroic role.

Aim: This study is going to assess the prevalance of prolonged grief diagnoses and it will evaluate the severity of the symptoms of depression, anxiety and complicated grief two months after a loved one is lost. We also intend to study which variables associated with the risk of grief could be more decisive when diagnosing it, its symptoms and the consequent emotional distress.Method: A total of 66 families of patients in the Palliative Care Unit (PCU) at Hospital San Cecilio in Granada have been evaluated. Measurements were taken two months after the death. This investigation has explored the existing emotional distress using the following questionnaires: Beck Depression Inventory (BDI-II), Beck Anxiety Inventory (BAI), Inventory of Complicated Grief (ICG) and Prolongued Grief Disorder (PG-12).Results: The results show that 33.3% and 21.21% of the sufferers had high levels of depression and clinical anxiety two months after the death. The prevalence of prolongued grief diagnoses, according to the PG-12, is 10.6% and 53.03% of the participants showed symptoms of complicated grief according to the ICG. Additionally, statistically significant differences are found in the sufferers with and without a prolongued grief diagnosis and scores in the ICG and BDI-II. The family’s financial situation is linked to the presence of symptoms of anxiety and depression and complicated grief, with the most determining variable being the risk of grief. Finally, the greater the age of the deceased and the longer the time spent in the PCU is linked to fewer symptoms of grief. However, important links have been found between the sufferers who have experienced stressful critical events prior to losing their loved one, with symptoms of depression, anxiety and complicated grief.Conclusions: The high numbers of cases of symptoms of complicated grief and levels of anxiety and clinical depression two months after a death suggests that early interventions should be carried out in those individuals with greater vulnerability.

El trabajo se centra en el análisis de los pecados relacionados con el dinero en el Inferno de Dante y en la primera traducción castellana de la primera cantiga de la Commedia, obra del arcediano de Burgos Pedro Fernández de Villegas. La traducción, compuesta en coplas de arte mayor y acompañada de un enciclopédico comentario, se publicó en 1515. Particular atención se dedica a la reflexión sobre el problema del mal uso del dinero que Villegas desarrolla en la glosa de los cantos en que con más vigor se levanta la voz de Dante para denunciar la gravedad del pecado de la sed de riquezas. Se analiza la postura del traductor español ante el tema comparándola no sólo con la de Dante sino también con la de Cristoforo Landino, autor del Comento sopra la Comedia, obra exégetica que se publicó por primera vez en Florencia en 1481 y que representó el punto de referencia privilegiado de Villegas.

Durante el siglo XIII se produjo una sucesión de revueltas que supuso la desaparición del Imperio almohade y su sustitución por poderes regionales en al-Andalus, el Magreb y el Magreb al-Aqsà. La historiografía ha presentado el surgimiento y pugna entre estos poderes como un fenómeno social, político e, incluso, cultural y religioso, con el que se ha podido explicar su aniquilación o marginalización. Este trabajo pretende contextualizar los hechos desde una perspectiva medioambiental, de forma que la desintegración del califato almohade, el surgimiento de aquellos poderes y la progresión de los reinos cristianos en la península ibérica puedan entenderse desde una visión global de cambio climático y una posible crisis agrícola.
