Recent research on local and regional economic development has focused upon transformations in local governance and institutional capacity. It has been argued that local authorities have ceded power to other actors and institutions involved in economic development and regeneration, and that the success of local and regional economic development is closely related to the strength of 'institutional capacity' within an area. In this paper, we examine these claims with reference to the operation of EU Structural Funds in the Humber Sub-region of the UK. Previous research on local governance and institutional capacity has had a limited empirical focus, drawing conclusions from studies of either economically 'successful' regions or regions undergoing regulatory and institutional transformation and precluding analysis of the nature and conditions of local governance and institutional capacity in less developed regions. Our case study evidence not only suggests that arguments about the declining influence of the local state are overdrawn, but also indicates a need for more nuanced accounts of the role of institutional capacity in regional development.  相似文献

This article re-examines the partition of East Africa. It first outlines the existing historiography, namely the dominant geo-strategic Nile model, and suggests that there are two major areas of weakness upon close analysis: a lack of documentary evidence; the way the sequence of actual events and policy decisions is inconsistent with the main thesis. Second, using a wide range of sources, a new chronology of events will be proposed that divides the annexation process into three separate stages. The article will first expose the importance of the prelude to partition in determining its ultimate geographical scope, in particular Anglo-German relations, local treaties and the commercial expectations for the lakes region. The second and third sections will expose the importance of public opinion in formulating a forward policy in the region. Finally, building on this, it will be argued that the role of Britain's anti-slave-trade policy needs to be fully acknowledged, with regard to Britain's raison d'être for establishing a formal presence on the mainland in 1885 with the occupation of the territories encompassing modern Kenya and Uganda in successive stages from 1885 to 1895.  相似文献

Newly created academic programs at Brazilian universities have provided the impetus for new archaeological projects in southeastern South America during the last two decades. The new data are changing our views on emergent social complexity, natural and human-induced transformation of the landscape, and transcontinental expansions and cultural interactions across the Río de la Plata basin during the Middle and Late Holocene. We concentrate on six major archaeological traditions/regions: the Sambaquis, the Pantanal, the Constructores de Cerritos, the Tupiguarani, the Southern Proto-Jê, and the middle and lower Paraná River. Diverse and autonomous complex developments exhibit distinct built landscapes in a region previously thought of as marginal compared with cultural developments in the Andes or Mesoamerica. The trajectories toward increased sociopolitical complexity flourished in very different and changing environmental conditions. While some groups were pushed to wetland areas during a drier mid-Holocene, others took advantage of the more humid Late Holocene climate to intensively manage Araucaria forests. The start of the second millennium AD was a critical period marked by an increased number of archaeological sites, the construction of ceremonial architecture, and the intensification of landscape transformation; it also was marked by the rapid expansion of influences from outside the La Plata basin. The Amazonian Tupiguarani and Arawak newcomers brought with them significant changes in technologies and social and political structures, as well as novel landscape management practices.  相似文献

In Great Britain, financial infrastructure withdrawal and community economic decline have focused attention on the capacity of locally "alternative" financial institutions to combat social and financial exclusion. This paper examines one such institution, the residential or "community" credit union, which provides a low-cost source of credit for members drawn from a common bond area usually based upon place of residence and/or work. Although community credit unions have traditionally been seen as providing individuals and communities with the opportunity to access credit and savings facilities in areas where there has been contraction in bank and building society provision (the financial "mainstream"), ongoing attempts exist to move away from the traditional role of community credit unions. This transition has set up three main challenges for the British credit union movement, discussed in this paper as follows: (1) a struggle over the attempt to redefine the "model" credit union within the national credit union movement; (2) the changing regulatory context for credit union development, including attempts to embrace credit unions within New Labour policies on social exclusion; and (3) a "local" challenge, including the incorporation of credit unions into community economic development initiatives. The paper considers how these challenges feed into wider understandings about the social relations, categorisation and autonomy of locally "alternative" financial institutions. We argue that future research on geographies of financial inclusion focusing on "alternative" institutions and their relationship to the financial mainstream needs to pay close critical attention to potential contradictions and tensions operating at different, yet intersecting spatial scales.  相似文献

Investigations of soil erosion by 137Cs method brings uncertainties of different nature. The estimation of the 137Cs local inventory is associated with problems of data comparison and instrumental errors. In order to avoid systematic errors, the rate of soil erosion determined by the 137Cs method is compared with the values obtained for other radioactive elements. Soil parameters must be regarded too. The aim of the work was to test the character of 137Cs and 40K distribution in the topsoil vertical section for determination erosion-accumulation type and ratio in different time spans. The topsoil thickened by different types of erosion-accumulation processes was sampled at a 2–3 cm interval. Soil samples were analysed by means of scintillation gamma spectrometry. The relationship between 137Cs and 40K inventories was weakest in the topsoil formed by mixing of soil material during the installation of artificial drains. Based on climatic characteristics, variations of theoretical soil accumulation rate in the last 50 years were calculated for the topsoil accumulated predominantly by water erosion. 40K and 137Cs correlation in the bottom of vertical section of topsoil or arable horizon are closest and this section may be used as a complementary parameter determining the local inventory value.  相似文献

Experience and History: Phenomenological Perspectives on the Historical World presents the summa of David Carr's phenomenological approach to history. I acknowledge the value of this perspective, but I find it doubtful that a phenomenological account can replace the paradigms of memory and representation against which Carr pits it. The concept of historicity is, rather, complementary in that it alerts us to the prethematic presence of history. Phenomenologically, Carr's attempt to tie history closely to experience runs into problems as it is based on a questionable use of Husserl's notion of retention and risks blurring the distinct temporality of history. At the same time, the central concepts of Carr's approach, both experience and narrative, could be deployed in further ways. As literary scholars have come to emphasize, narrative triggers experiences in its readers. Thus, even if it is impossible to recreate the experiences of historical protagonists, narrative lends itself to giving readers a sense of the experiential dimension of the past. In this sense, narrative is not only a medium of representation, but also a means of presence.  相似文献

Sub-fossil oaks from Smarhoń in Belarus have been investigated and tree-ring chronologies were assembled. According to radiocarbon dating, the oldest oak grew from 5782–5612 cal BC and the youngest from 1575–1747 cal AD. Radiocarbon and dendrochronological dating of 97 samples, four single series, 10 mean curves (containing 2–9 series) and three chronologies (10–25 series) were constructed. The longest chronology (No. 16), covering 549 years, was absolutely dated against various oak chronologies of Polish/Baltic origin to AD 778–1326. Germination and dying-off phases were assessed from the three best replicated chronologies. A spectral analysis of the chronologies provided cycles of variable length, on average of 25 years.  相似文献
