The recent developments of the economic theory suggest that due attention to territorial context increases efficiency and improves delivery of the policies. This in turn calls for better linkages between spatial and socio-economic efforts. The paper analyses the concept of policy territorialization and proposes policy tools for that purpose. The relevant theoretical models are used, mainly evolutionary economics and new economic geography. The key outcome is a set of territorial keys supposed to enhance territorial approach in developmental policies. Also some plausible ways of making use of those keys are proposed and then tested using Polish territory as a case study.  相似文献

The Mesolithic–Neolithic transition in north-west Europe has been described as rapid and uniform, entailing a swift shift from the use of marine and other wild resources to domesticated terrestrial resources. Here, we approach the when, what and how of this transition on a regional level, using empirical data from Öland, an island in the Baltic Sea off the Swedish east coast, and also monitor changes that occurred after the shift. Radiocarbon dating and stable carbon and nitrogen isotope analyses of bones and teeth from 123 human individuals, along with faunal isotope data from 27 species, applying to nine sites on Öland and covering a time span from the Mesolithic to the Roman Period, demonstrate a great diversity in food practices, mainly governed by culture and independent of climatic changes. There was a marked dietary shift during the second half of the third millennium from a mixed marine diet to the use of exclusively terrestrial resources, interpreted as marking the large-scale introduction of farming. Contrary to previous claims, this took place at the end of the Neolithic and not at the onset. Our data also show that culturally induced dietary transitions occurred continuously throughout prehistory. The availability of high-resolution data on various levels, from intra-individual to inter-population, makes stable isotope analysis a powerful tool for studying the evolution of food practices.  相似文献

The focus of this article is on product innovations introduced by firms (establishments) and the collaborations they enter into with other firms and organizations in carrying out this activity. The theoretical framework combines innovation theories with the literature on regional innovation systems and the knowledge-based economy. Empirically we have investigated characteristics of collaboration among manufacturing establishments in the region of East Gothia in Sweden, with specific focus on the number of employees involved in the innovation projects, mechanisms of knowledge transfer between organizations, as well as financing and patenting in relation to product innovations.  相似文献

晋侯苏编钟铭文反映了西周巡狩行为。铭文中"省"即是周王的巡狩,与征伐蛮夷戎狄的军事行为相关。铭文反映的巡狩折射出西周晚期政治的种种特点,如蛮夷戎狄叛乱频繁,王权衰落,周王不得不进行挣扎,王师的战斗力下降等等。晋侯苏这样的大诸侯是周王巡狩的武力支持,他们有权力控制蛮夷戎狄,但仍臣属于周王,他们与文献中的"方伯"有共同之处。  相似文献

Since the Rio Conference of 1992, which declared the conservation of biodiversity and the creation of national parks to be priorities, resettlements resulting from conservation projects in Central Africa have been on the increase, as people living inside protected areas are relocated. Hardly any of these resettlements have been successful. There has been resistance to moving in the first place, and even returns to former villages inside the national parks. Resettlement is still the most common way to deal with people who happen to live in African national parks, but the risks which arise from these resettlements have led some scientists to rethink their position. This article focuses on the Congo River Basin. It reviews the only ‘official’ relocation programme in the region (Korup National Park, Cameroon) and evaluates different approaches of national parks in Equatorial Guinea, Cameroon, Central African Republic, Congo (Brazzaville) and Gabon. The author uses the Impoverishment Risk and Reconstruction model introduced by Cernea to evaluate the risks faced by the resettled populations, and to elaborate some social and environmental guidelines to mitigate them.  相似文献

In this paper we explore the potential use of ergosterol (5, 7, 22-ergostatrien-3β-ol) as a possible biomarker for yeast and alcohol fermentation, applying the analytical technique previously used routinely in Swedish archaeology for the analysis of lipid residue in prehistoric pottery. Taking note on the connection between brewing, baking and agriculture the frequency of vessels showing gas chromatography mass spectrometry traces of this compound in lipid residues from a clearly agricultural Bronze Age/Early Iron Age population was compared with the same signal in a clearly non-agricultural Neolithic foragers pottery population. The result shows a small but statistically significant difference between the two populations, indicating a connection between the presence of ergosterol in lipid residues from pottery and agriculture. The results are also discussed in terms of varying cleanliness, degradation, deposition conditions and contamination. Suggestions for future research include the use of a more sensitive analytical protocol in order to improve detection limits and to include materials from clear agricultural Neolithic vessel populations.  相似文献
