Administrative regions do not necessarily correspond to areas that are homogenous in terms of innovation intensity. Although this has been recognized in the literature, quantitative evidence that explicitly considers this problem is rare. Using spatial exploratory analysis on detailed regional data derived from a census of R&D performers in the Czech Republic, we identify local spatial clusters of R&D activities and assess the extent of their (mis)match with administrative borders. Overall, the results support the arguments for regionalization of innovation policy. However, the existing policy units do not appear well suited for this purpose. On one hand, there is a need for policy coordination between multiple administrative regions. On the other hand, however, there are diverse patterns within them. Similar problems are likely to haunt the regionalization process in many other countries, which is alarming, as the regional accent of innovation policies becomes ever more vehement over time.  相似文献

In this paper we show the results of a study concerning 42 axes, mainly discovered in the Copper Age pile dwellings of Ljubljansko barje (central Slovenia) and in the neighbouring areas of Caput Adriae. The studied shaft‐hole axes, characterized by homogeneous typology but slightly different raw materials, have been called ‘Ljubljana‐type’ axes (Lt). The raw materials show a common OIB‐like signature and metamorphic and spilitization features that recall oceanic conditions. The typological and geochemical characteristics and the very high percentage of Lt axes among the polished stone axe assemblages of Ljubljansko barje suggest that the raw material was probably gathered from one or more relatively small outcrops close to Ljubljansko barje. Similar igneous rock types outcrop in the presumably Palaeozoic diabase/shale complex (Eisenkappler Diabaszug), intruded by the northern Karawanken plutonic belt. A probable provenance from this area, particularly rich in copper ore deposit, would confirm the important role of Ljubljansko barje as a metallurgical district, as well as a strong relation between lithic raw materials and Cu cultivation districts during the Copper age.  相似文献

A recently described case of putative early tertiary syphilis in a young adult male from 6th century Anglo‐Saxon England exhibits a distinctive endocranial pathology. A case–control study using both clinical and archaeological materials was performed to investigate a possible association of the pathology with syphilis. Scanning electron microscopy and microcomputed tomography were used to image the syphilitic case and normal cranial material. Although the pathology does seem to have an association with syphilis (OR = 13.14), the sample size is small, and the authors caution against overinterpretation of the results. The study confirms observations by other authors suggesting the lesion has some association with a range of pathological conditions. Any association with syphilis seems to be restricted to the early tertiary stages and is possibly absent in the later stages of the disease. The morphological differences present in the samples observed by scanning electron microscopy and microcomputed tomography illustrate the abnormal nature of the vascularity within the syphilitic cranium. The widespread presence of similar lesions within other tubular bones leads the authors to propose hypothesis that unresolved angiogenesis is the underlying mechanism behind the skeletal changes in tertiary syphilis. This angiogenic model accounts for several diverse characteristics in the progression of skeletal disease resulting from infection by spirochetes of the Treponema pallidum family.

This article explores the contentious relation between the absence of democracy in the Middle East and the use of armed violence by Islamist groups in light of the Arab Spring. Its main objective is to decipher the evolving positions of former and current groups who used or promoted violence and to relate them to broader academic debates on violence and democracy on the one hand, and deradicalization on the other. This research demonstrates that the large majority of former Islamist militants in Egypt reject any sort of violence in post‐Mubarak Egypt, even if they have not all renounced their religious legitimization of violence in the past. Second, it reveals that even if they maintain a religious opposition to democracy in Egypt, the opening of political opportunities and their progressive joining of the political process has favorably led most of them to accept democratic practices in reality. Third, it adds that the voice of those currently promoting violence in Egypt has been marginalized and that their main alternative has been the promotion of armed violence in Syria; and last, it stresses two potential security threats unrelated to the opening of political opportunities in post‐Mubarak Egypt and to the general debate on democracy and violence. First, local grievances in Sinai have led to violence in the past and are still to be dealt with. Second, the current political deadlock can potentially lead to localized and specific armed activities that could start a cycle of violence. This research is based on field research in Egypt and uses repeated interviews of leaders and members of the two main former militant groups, al‐Jama?ah al‐Islamiyya (the Islamic Group) and Jama? al‐Jihad (the Jihad Group) as well as interviews with militants of the salafi jihadi trend and their supporters in Cairo.  相似文献

This article seeks to bring together studies of community from both the New and Old Worlds and examine their various strengths and weaknesses. Whilst applauding many of the recent developments, particularly the emphasis on communities as the outcome of practice and agency, I suggest that there are three specific difficulties present in the current studies of community: an underlying subtext which supports modern political notions of community as a timeless form of sociality; a prominent anthropocentric vision of community as the province purely of human beings; and a failure to fully embrace the role of affect and emotion. By rethinking communities as assemblages, this article seeks to build on the firm foundations constructed in the last 15 years to present new possibilities for taking this important concept forward.  相似文献

We argue in this paper that Levantine rock art in the Spanish Mediterranean basin allows us to ‘map’ the economic landscape of its makers. Rock art would be the ‘monumental’ side of a dual process of landscape construction: on the one hand, rock art is the first ‘cultural’ action on the landscape beginning in the Early Neolithic; on the other hand, the first evidence of active modification of the Mediterranean vegetation comes from this period. But this evidence as well as other kinds of archaeological remains are still relatively scarce in the uplands; rock art is therefore the most complete type of evidence we can use to support an early use of the Mediterranean upland environment. We use statistical and geographical analysis, together with archaeological, ethnohistorical, and ethnographic sources and pollen data, in order to support the idea of early use and exploitation of the Mediterranean uplands since the Neolithic, and into contemporary times.  相似文献

The article investigates the ‘long 1970s’ (1968–82), when Hungary re-orientated its economic and foreign-trade relations. Hungary was always a promoter of a deepening of Council for Mutual Economic Assistance (CMEA) co-operation and when it noticed that socialist integration stagnated at the level of the bilateral exchange of commodities, Budapest gradually launched a policy of opening up to the world outside the CMEA. The year 1977 was a turning point in economic policy. Hungarian elites' thought and attitude towards the West changed, but not independently of the world economic crisis and its impact on Hungary. The oil crisis sharpened latent tensions, and behind the robust growth serious problems appeared. Although Hungary intensified its interrelations with the West and the Third World, the country was not able to profit from the advantages of international trade and co-operation. The article is based on state, party and senior economic leaders' archives.  相似文献

Abstract

In this essay the author summarizes the argument of his book entitled The Myth of Religious Violence, whose main contention is that there is no reason to suppose that people are more likely to kill for a god than for a whole other host of “secular” ideologies and practices that behave in the way that “religions” do. The author then goes on to respond to various critiques that have been made of the book since its appearance in 2009.  相似文献
