This volume constitutes the proceedings of the 8th IFIP WG 8.1 Conference on the Practice of Enterprise Modeling held in November 2015 in Valencia, Spain. The PoEM conference series started in 2008 and aims to provide a forum sharing knowledge and experiences between the academic community and practitioners from industry and the public sector. The 23 short papers accepted were carefully reviewed and selected from 72 submissions and are organized in eight sections on Evolving Enterprises, Securing Enterprises, Making Empirical Studies, Investigating Enterprise Methods, Acquiring User Information, Managing Risks and Threats, Engineering Methods, and Making Decisions in Enterprises.

These archaeological studies offer to provide an alternative tour through Vesuvian cities. One way to see Pompeii, for example, is via its hydraulic systems, from the higher parts to waterlogged landfills at the mouth of Sarno. They invite you to walk the streets amidst the traces of regulation issued in municipal law and the free initiative of those who built and maintained the sidewalks. The graffiti and paintings allow us to take a tour specially designed to understand the tastes and devotions of the inhabitants of the Vesuvian cities. Thus, disparate themes researched separately may be presented here as a coherent work that initiates the visitor into Vesuvian studies. Each author gives us a particular tour of the specifics of the cities and villages of the Vesuvian area, its story, furniture, findings and the research process that has been developed over many years.

This collective work, carried out by both senior and beginning researchers, is for those scholars who have their gaze fixed on the fascinating mosaic of cultures that was the North-African world from the moment Rome appeared in the region. Even before this date, the arrival of Phoenicians on the continent and their subsequent spread throughout the north of it, initiated a rich process of contacts, interchanges and relations with the Libyan-Berber populations that inhabited the zone from time immemorial. To this scene of ancient cultural diversity -which also included an Egyptian component- Rome brought its own riches, generating in the region new episodes of cultural and religious syncretism. All these subjects are treated in the present book through some specific scientific contributions whose geopolitical frame is the whole Proconsular Africa. Most of the articles in this volume are dedicated to the world of images, but others also treat many other issues as Historiography, Archaeology of Architecture, Libyan-Berber ethnicities and even cultural parallels between North Africa and the Iberian Peninsula.

The History of archaeological research has only recently become a research topic of interest within Spain. A congress, Colecciones, arqueologos, instituciones y yacimientos en la Espana de los Siglos XVIII al XX, was held at the Universidad Complutense de Madrid in 2016 designed to bring this topic to the fore. Eleven papers are presented in this proceedings volume. They address several aspects from different perspectives that collectively enrich the historiography of Spanish archaeological research. | La Historia de las investigaciones arqueologicas es un campo de estudio muy reciente en el caso espanol. No obstante, las ultimas decadas han sido muy fructiferas en esta linea de investigacion. Colecciones, arqueologos, instituciones y yacimientos en la Espana de los Siglos XVIII al XX es un volumen que recoge ese testigo con once trabajos originales que traen a la primera linea la historiografia de la Arqueologia espanola. Estos trabajos, fruto de un congreso homonimo realizado en la Universidad Complutense de Madrid en 2016, abordan diferentes temas y perspectivas que abarcan importantes aspectos de la tematica tratada con una variedad geografica que atiende la diversidad y riqueza de la historiografia arqueologica espanola.
