The municipality of Olavarría, Buenos Aires province, Argentina, has a rich, diverse, and ancient natural and cultural heritage, although this is not well known by the local community. For this reason, an itinerant exhibition was developed to promote public access to scientific information and community awareness concerning the importance of local heritage. This project was the starting point of an integral programme of public outreach and science education, whose main goal is to facilitate intellectual and physical access to academic knowledge by local communities. After seven years of development, several lessons have been learned, including the need to increase stakeholders’ participation and the exploration of new strategies of communication in order to engage different segments of the public.  相似文献

International cultural development projects entail a neoliberal agenda that frequently echoes colonial ideologies and discourses. Using the case study of Chaouen, a northern city in Morocco, I argue in this paper that former colonies and aid-receiving countries usually overlap, and serve the former metropolises to continue controlling the former colony’s human and economic resources. I discuss how the former colonial power, in this case Spain, regulates and promotes a particular heritage discourse that has conveniently been depoliticised. I further contend that in line with previous colonial narratives, Spain has silenced the painful history of struggle and resilience of the inhabitants of Chaouen.  相似文献

The study of material culture generated by military engagements has created an emergent sub-discipline of archaeological studies centred on battlefields. This approach has developed a particular and sophisticated methodology that is able to deal with the fact that archaeologists will often not find either structures or a useful stratigraphical record on the site, as the material remains of the battle will basically be metallic objects carried by combatants. It is therefore rather complicated not only to test hypotheses about battle events based on archaeological data, but also to validate the methodology used. Here we propose the use of agent-based models to explore these issues in the case of eighteenth-century battlefield archaeology. The simulation is divided into four different steps. Firstly, a battle is simulated in order to generate realistic virtual archaeological remains left by an engagement between two armies of this era. We then simulate the loss of information that the passing of time produces in the battlefield. The third step involves simulating the archaeological survey, enabling us to explore different survey strategies and the impact on the interpretation of the event itself. Finally, we design a confidence index in order to compare the results of the different virtual excavations using spatial analysis and statistics. The results show that the methodology is fully functional in terms of understanding a battle, and it allows us to suggest new strategies to improve fieldwork and to develop new ways of exploring these particular archaeological sites. It is concluded that the described approach illustrates how simulation can be used to explore methodological issues of archaeological science.  相似文献

In this study, we aim at evaluating the role of path-dependent and past-dependent forces in the historical trajectory of clusters. For that purpose, we study the life cycles of four of the main industrial clusters in the Basque Country (paper-making, electronics and information and communication technology, maritime industries and aeronautics) and analyse the factors that account for the origin, development, maturity and, if so, decline of those clusters, considering factors related to both cluster dynamics and the regional environment. Our analysis shows that the existence of a life cycle does not imply a straightforward growth path. Clusters follow multiple growth patterns in their development. The heterogeneity of growth patterns may be, in some cases, due to different initial conditions. However, despite similar initial conditions and/or resource endowments and opportunities for development, we can observe heterogeneous evolutionary patterns. Clusters react differently to the same external shocks (e.g. international demand, global competition and technological change) and evolve differently according to their capabilities.  相似文献

Regional policies seek to enable regions to increase their competitiveness and development, and as such one priority Objective of activities financed by Structural Funds is higher employment, higher productivity and economic activity. How efficiently the regions apply the funds is a fundamental issue for the development and continuity of regional policies. We therefore consider that determining the efficiency of European regional policies is an issue of high importance, and this is the main aim of this study. We have considered it appropriate to use the available information to apply a mathematical technique known as Data Envelopment Analysis (DEA), which allows us to calculate the technical efficiency and inefficiency of the Structural Funds applied in the Objective 1 regions for the period 2000–2006. Furthermore, we wish to determine if the regions have been more efficient in creasing their levels of employment or in increasing productivity. Our study applies this methodology along with other methods like regression analysis, profit analysis and factorial analysis to determine the variation in the rate of unemployment and productivity in these European Regions. The study reveals that only eight regions are efficient, although none of them is run in all the models.  相似文献

Financialization is a major trend in Western economies. This paper shows, on the one hand, how it changes the management criteria and, on the other hand, the limits to financialization in the property sector. Between 1992 and 2004, about 15% of Swiss pension funds' wealth was invested in property. As far as their investment policy is concerned, pension funds have two choices. First, they can directly own, and have management responsibility for, the properties in their portfolios. Alternatively, they can buy shares in mainly Zurich-based investment vehicles. In the first case, pension funds require staff with the relevant expertise along with the knowledge of property markets. Investments have a regional focus and are assessed internally by the funds. In the second case, pension funds are merely investors and investment appraisals and comparisons are made on the basis of market criteria such as yield, diversification in relation to risk and liquidity. In this case, property investments focus solely on the country's main urban areas.  相似文献

Chloride (Cl) ions diffuse into iron objects during burial and drive corrosion after excavation. Located under corrosion layers, Cl is inaccessible to many analytical techniques. Neutron analysis offers non‐destructive avenues for determining Cl content and distribution in objects. A pilot study used prompt gamma activation analysis (PGAA) and prompt gamma activation imaging (PGAI) to analyse the bulk concentration and longitudinal distribution of Cl in archaeological iron objects. This correlated with the object corrosion rate measured by oxygen consumption, and compared well with Cl measurement using a specific ion meter. High‐Cl areas were linked with visible damage to the corrosion layers and attack of the iron core. Neutron techniques have significant advantages in the analysis of archaeological metals, including penetration depth and low detection limits.  相似文献
