The Historiographic Problem of the Differentiation Between Epipalaeolithic and Neolithic as a Conceptual Debate

Se analizan las dificultades que el modelo histórico-cultural plantea para estudiar el problema de la transición de los cazadores-recolectores a las sociedades tribales. Este debate está en el marco del panorama contemporáneo de la arqueología prehistórica y se sugieren algunas alternativas de orden socio-económicas, desde una posición teórica definida.We analize the difficulties that the historical-cultural model present in order to study the problem of the transition from the hunterer-gatheres to tribal societies. This discussion is in the framework of the Contemporary view in Prehistoric Archaeology and some socioeconomic alternatives are suggested from a theoretical position

La ocupación prehistórica de los medios kársticos de montaña en Andalucía

Las montañas andaluzas presentan un porcentaje elevado de relación con los medios kársticos. Además, en el transcurso de las últimas decenas de miles de años de la evolución antrópica y ambiental, han sido aprovechadas intensamente por el hombre. En este trabajo se presentan los conocimientos existentes sobre la ocupación en la Prehistoria de los medios kársticos de montaña andaluces, desde los orígenes de la ocupación humana, en el Achelense avanzado, hasta la Edad del Bronce.The Andalusian mountains show a high degree of correlation with karstic environments. Besides, during the last tens of thousands of years of antropic and environmental evolution, have been intensively utilized by the man. The existing knowledge on the human occupation of the karstic set- tings during Prehistory, from the Andalusian mountains in the later Achelien, to the Bronze Age, is presented in this paper

Relationship and contacts of the pleistocene hunter-gatherer societies with mode-III technology between northern Africa and the southern Iberian Peninsula

We present the natural environment of the historic region of the Strait of Gibraltar. We evaluate the similarities in the south of the Iberian Peninsula and North Africa in geography, geology, environ- ment and resources. The paper shows a summary of the important research carried out about the history of hunter-gatherer societies in this area. We emphasise the importance of the similarities of the Mode I and II technologies. On the other hand specifically, the Mode III technology scene is valued on both sides of this Atlantic and Mediterranean region. We reflect on the similarity of exploitation in order to make use of the marine resources by different human groups

Las ocupaciones humanas del sur peninsular por sociedades cazadoras-recolectoras con tecnocomplejos vinculados al Paleolítico Superior y Epipaleolítico. Estado de la cuestión y perspectivas de la investigación.

En esta contribución expondremos unas ideas del estado actual de la investigación y de las perspectivas de estudio que ofrecen los estudios de las sociedades cazadoras-recolectoras adscritas según criterios normativos al Paleolítico Superior y a su transición a las comunidades tribales neolíticas en el Sur peninsular. Partimos de unas reflexiones metodológicas de nuestra visión de la Prehistoria desde una perspectiva social. Exponemos una síntesis crítica de la Historia de la investigación y planteamos las bases de la secuencia y los problemas latentes en la investigación

Fuzzy heterogeneous neurons for imprecise classification problems

In the classical neuron model, inputs are continuous real-valued quantities. However, in many important domains from the real world, objects are described by a mixture of continuous and discrete variables, usually containing missing information and uncertainty. In this paper, a general class of neuron models accepting heterogeneous inputs in the form of mixtures of continuous (crisp and/or fuzzy) and discrete quantities admitting missing data is presented. From these, several particular models can be derived as instances and different neural architectures constructed with them. Such models deal in a natural way with problems for which information is imprecise or even missing. Their possibilities in classification and diagnostic problems are here illustrated by experiments with data from a real-world domain in the field of environmental studies. These experiments show that such neurons can both learn and classify complex data very effectively in the presence of uncertain information.Peer ReviewedPostprint (author's final draft

Fuzzy heterogeneous neural networks for signal forecasting

Fuzzy heterogeneous neural networks are recently introduced models based on neurons accepting heterogeneous inputs (i.e. mixtures of numerical and non-numerical information possibly with missing data) with either crisp or imprecise character, which can be coupled with classical neurons. This paper compares the effectiveness of this kind of networks with time-delay and recurrent architectures that use classical neuron models and training algorithms in a signal forecasting problem, in the context of finding models of the central nervous system controllers.Peer ReviewedPostprint (author's final draft
