This paper investigates the impact of the main criterion employed by the European Commission for the allocation of the largest portion of Structural Funds, based on the threshold of the 75% of European Union (EU) average gross domestic product (GDP) per capita. We focus on the 2014–2020 programming period and on EU-15 regions to analyze if this criterion has penalized some of them, as a consequence of the 2004 EU enlargement, which has represented an exogenous shock in the allocation process, due to the economic backwardness of new member states. Through the application of Synthetic Control Methods and Difference-in-Differences estimators at different geographical scales, we show that regions that did not obtain the less developed status in both the programming period 2007–2013 and 2014–2020, but that would have obtained it in the period 2014–2020 without the 2004 EU enlargement, experienced a significantly lower GDP per capita growth between −10.5% and −5.7%. Conversely, territories that in the period 2014–2020 lost the less developed status, previously obtained in the time frame 2007–2013, were not characterized by a significantly lower economic growth, providing some evidence of the effectiveness of the safety net.  相似文献

In addition to a series of chronological markers (artefacts, pottery) in the archaeological contexts of ancient Tayma (NW Saudi Arabia), optically stimulated luminescence (OSL) and radiocarbon dating techniques were applied to generate reliable ages for the city wall system of the oasis. A massive aeolian sand deposit burying the oldest part of the outer wall of Tayma was sampled to obtain a minimum age for the construction of this wall. The sequence of OSL ages from the inactive dune (ID) (4900 ± 300 a, 5100 ± 400 a, 4400 ± 300 a, 3900 ± 200 a, 4000 ± 200 a) is in full accordance with 14C-AMS ages of charcoal embedded into the same dune (4190–4420 cal BP, 3870–4080 cal BP). Underlying alluvial samples from the inactive gravel sheet (IGS) in contrast give maximum ages for the construction which scatter between 6600 ± 300 a and 4900 ± 400 a. The new dating sequence provides evidence that the oldest part of the ancient city wall system already existed in the 2nd half of the 3rd mill. BC which is earlier than expected thus far from archaeological and architectural interpretation.  相似文献

This paper focuses on the use of web communication tools as a policy device to regulate access to theaters. By comparing the profile of what we call ‘tech-savvy’ spectators (i.e. audience using the website of a theater) with the profile of the general audience we examine whether the web can be regarded as an effective tool to address regular spectators or to reinforce the participation of different segments within the audience. The study suggests that the web appears to be the favorite direct marketing tool for informing or retaining ‘inexpert drama lovers’, namely those who fish in different types of performing arts events (i.e. opera, ballet, and classical concert) or attend different types of theatres. Moreover, internet may combat the aging of the performing arts audience by giving priority to access to those that are more familiar with the new technologies (i.e. younger audience).  相似文献

This article examines Australia's long-held doubts about Britain's willingness and ability to maintain a significant military presence in Southeast Asia, where Australia's main strategic interests lay. The article argues that Australian concerns long predated the Wilson government's attempt to disengage from east of Suez in the mid-1960s. In doing so, it shows that the Menzies government had since the mid-1950s become increasingly concerned about Britain's resolve and capacity to station substantial forces in the region. In illustrating the extent to which policy-makers in Canberra became suspicious of British long-term strategic aims in Southeast Asia, this article reveals some interesting aspects of the changing nature of Anglo-Australian relations in the post-war period.  相似文献

Environmentalist concerns over the state of Nepal's "fragile forests" resulted in the establishment of Community Forestry projects. These community‐based projects are partnerships between the state and community user groups that invest user groups with a great deal of control over their forests. Project implementation, however, begins with the assumption that users have little prior knowledge of forest management and need to be taught modern silviculture. I examine the extent to which different community members embrace notions of professional forestry materially and symbolically. The development of written management plans, the need for careful accounting records and the promotion of silviculturally based management strategies by District Forest Officers serve to (re)inscribe differences between users based on education and literacy. Which users embrace these discourses and practices and for what purposes lends insight into the workings of neoliberalism and how it is implicated in the reconfiguring of social and power relations within localities and, in this case, the consequences of this for ecological change. It is argued that the promotion of expert knowledge and professional practices in Community Forestry is often used as a somewhat contradictory vehicle for educated elites to retain control over forest management, thus undermining some of the key objectives of the program.  相似文献

This article discusses the complex and contradictory nature of ‘abject citizenship’ as it is experienced by teenagers from a small town youth centre. Lines between inclusion and exclusion are blurred by these resilient youth as they re-appropriate central and accepted spaces as well as marginalized spaces to destabilize the categories of insider and outsider. This snapshot ethnography demonstrates how these young disadvantaged citizens create uneasiness for those who enjoy full citizenship and turn experiences of rejection into experiences of empowerment and belonging for the abject.  相似文献
