Evolution of knowledge bases in European regions: searching for spatial regularities and links with innovation performance

This paper aims at a greater comprehension of the distribution of differentiated knowledge bases and their association with innovation performance. Drawing on evolutionary economic geography, we applied a combinatorial and dynamic view on knowledge bases. The main contribution is the examination of changes and transformations of knowledge bases over time in particular group of regions in Europe and links with innovation performance. Our study revealed systematic regularities between regions with different innovation performance and their knowledge bases. With decreasing regional innovation performance the volatility of knowledge bases over time increases. Innovation leaders evinced stability over time and the most balanced composition of knowledge bases (compared with Central and Eastern Europe regions). Western European countries and regions exhibit the most balanced structure of knowledge bases. An important complementarity and synergy has been identified in the close relatedness of the symbolic knowledge base to the analytical knowledge base. The highest intensity of SME cooperation takes place in regions with a strong analytical base and in regions with the most balanced mix among all three bases (particularly in the UK, the Netherlands and Belgium. Underperforming in innovation show a balanced mix of synthetic and symbolic knowledge bases.     

European Cohesion Policy impact on development and convergence: a local empirical analysis in Portugal between 2000 and 2014

Substantial European Structural and Investment Funds (ESIF) monies have been directed at regional economic and social development in Portugal in which Portuguese local government plays a vital role. Given the magnitude of funding, an important question turns on the effect of the ESIF on overall local authority performance. This paper focuses on the impact of the ESIF on Portuguese municipality performance and development. In particular, it investigates whether the ESIF improved the performance of Portuguese local government and which factors best explain its effect on municipality development. The analysis considers all 308 Portuguese local authorities for the period 2000–2014. Various policy implications flowing from the empirical results of this analysis are explored.     

Performing a different narrative: museum theater and the memory-work of producing and managing slavery heritage at southern plantation museums

In the southeastern United States, operators of plantation museums have traditionally engaged in a selective and romanticised remembrance of the antebellum past that has regrettably silenced and marginalised the historical experiences and struggles of enslaved African people. More recently, some plantation managers have sought to engage in the ‘memory-work’ using artistic practices to reconstruct and interpret slavery heritage for visitors. Our study explores museum theatre as a form of memory-work and suggests that theatrical performances of the memories of enslavement are an increasingly important but not yet fully understood strategy for recovering, embodying, and representing a different and hopefully more just narrative about enslaved Africans. We visit three plantation museums where managers hosted a theatrical performance of enslaved oral histories and explore the motivations and experiences of managers and the director of the slave performance. Realising the power and efficacy of theatrical performance as memory-work practice requires understanding how the management of the interpretation process can be difficult. We delve into the emotion-laden challenges confronting slavery-related museum theatre development at the North Carolina plantations and discuss the creative response formulated at the sites to help visitors work through unexpected feelings and understandings about the past.     

Invasive cordgrass (Spartina spp.) in south‐eastern Australia induces island formation,salt marsh development,and carbon storage

Invasive vegetation species can lead to major changes in the geomorphology of coastal systems. Within temperate estuaries in the southern hemisphere, especially Australia and New Zealand, the cordgrass Spartina spp. has become established. These species are highly invasive, and their prolific growth leads to the development of supratidal environments in formerly intertidal and subtidal environments. Here, we quantified the impact of Spartina invasion on the geomorphology and sequestration capacity of carbon in the sediments of Anderson Inlet, Victoria, Australia. Spartina was first introduced to the area in the 1930s to aid in land reclamation and control coastal erosion associated with coastal development. We found that Spartina now dominates the intertidal areas of the Inlet and promotes accretion (18 mm/year) causing the formation of over 108 ha of supratidal islands over the past 100 years. These newly formed islands are calculated to potentially contain over 5.5 million tonnes of CO₂ equivalent carbon. Future management of the inlet and other Spartina‐dominated environments within Australian presents a dilemma for resource managers; on the one hand, Spartina is highly invasive and can outcompete native tidal marshes, thereby warranting its eradication, but on the other hand it is likely more resilient to rising sea levels and has the potential for carbon sequestration. Whether or not the potential advantages outweigh the significant habitat change that is anticipated, any management strategies will likely require additional research into costs and benefits of all ecosystem services provided by Spartina including in relation to nutrient cycling, shoreline stabilisation, and biodiversity as well as in response to the longevity of carbon found within the sediments.     

Maritime territorialisation as performance of sovereignty and nationhood in the South China Sea

The South China Sea (SCS) is a conflict‐ridden international arena of rivalry between China, the USA, India, and the other ASEAN countries over sovereignty, resources and security. In this geopolitical clash China is the dominant force and Vietnam its main challenger. While most analysts assume that the various claims to the mostly uninhabited islands are motivated by the presence of submarine mineral resources, the conflicts evoke strong nationalist feelings in Vietnam and China, fuelled by narratives of the historical presence of fisheries and navies. By analysing the tension between complex territorial claims, new technologies and forms of knowledge applied by these states to delineate their material borders on the sea and vernacular notions of social space, this paper explores how sovereignty and nationality is enacted on a day‐to‐day basis. Thus, I argue that maritime territorialisation is a paradox of treating the sea as ‘land’ produced by the performance of a socially constructed image of the state geo‐body capitalising on strong nationalistic sentiments in China and Vietnam.     

Who we are at work: millennial women,everyday inequalities and insecure work

Based on research with millennial women in Canada, this article examines the process of workplace identity, or (un)conscious strategies of identity management that young women employ at work. First, despite increasing labour market participation from women, young women’s experience of the workplace can be one of precarity and insecurity. Many millennial women have responded with a ‘positive front’ – saying yes to all work tasks while highlighting their likability and acceptance of the status quo. This is not seen as a permanent strategy, but rather one that gets you into the workplace and ‘liked’ until your work speaks for itself. Second, and operating at the same time, young women also use tactics to confront intersections of ageism/sexism in the workplace. While some employ conscious strategies to be ‘taken seriously’ through dress, small talk, even taking on stereotypical traits of masculinity to be recognized as competent, others explicitly confront inequality through ‘girlie feminism’ with a pro-femininity work identity that challenges the masculine-coded norms of how a successful workplace operates and what it looks like. In jobs of all types, who we are at work is a constantly shifting negotiation between how we are treated and seen by others, the workplace as a social space, our past experiences and our own expectations. Considering young women’s work identities reveals how power and privilege operate in the workplace, and the possibilities of young women’s agential challenges to inequitable workplace norms and a precarious labour market.     

Maritime Culture in the Netherlands: accessing the late medieval maritime cultural landscapes of the north‐eastern Zuiderzee

This paper examines the theory and practice of the maritime cultural landscape in general, and projects the theoretical concepts and aspects involved on the highly dynamic late medieval north‐eastern Zuiderzee region in the Netherlands. The cultivation of land and marine erosion (floods and rising sea level) are considered as the main factors that caused the transformation of the physical landscape of this region from peatlands with freshwater basins into a tidal lagoon. As a consequence, multiple settlements drowned, large areas of land submerged, and culture and the landscape gradually became more maritime, giving the research area a cultural identity and dimension.     

Nitrogen isotopes and the trophic level of humans in archaeology

Human and domesticate animal bone collagen δ¹⁵N values in prehistory differ generally by 3‰ or more from Neolithic to post- Roman times in Northwest Europe, leading to an assumed dietary animal protein fraction of 60–80% using a standard interpretation of δ¹⁵N values. We examine the assumptions on which this model rests and the limitations of our knowledge in the analysis of δ¹⁵N values in archaeology. We have developed a set of models which, with small changes made in assumptions (on the order of 1‰), can produce substantially lower estimates of the dietary animal protein fraction for given δ¹⁵N values. We consider the implications of various dietary animal protein fractions on agricultural carrying capacities and human population densities in prehistory.     

华沙渠道与中美关系解冻:华盛顿决策内幕

在冷战的国际大背景下,尼克松政府对苏实施的“缓和”战略使得华盛顿打出“中国牌”,致力于改善同北京的关系。而1969年3月中苏边界武装冲突则为美提供了一个契机。在寻求同中国对话的渠道上,华盛顿首先想到的是华沙渠道,即第135次和136次中美大使级会谈,并为此做了充分的准备。尽管史实证明:华沙渠道的进展不像华盛顿期望的那样顺利,但基本上完成了预期的任务:表达了改善对华关系的愿望,并阐明了不会同苏联合作主宰东亚事务的立场。在华沙渠道完成了既定任务之后,华盛顿又将同北京的联络转为巴基斯坦渠道。
