Hoby on the island of Lolland in the western part of the Baltic Sea is strategically located in a coastal landscape offering abundant resources. In 1920, one of the most richly furnished so‐called “Lübsow type” graves dating to the first century AD was discovered at Hoby. The settlement associated with the grave was recognised in 1999. Excavations of the settlement between 2001 and 2016 have confirmed the central role of Hoby in the Iron Age society. The research has focused on the Iron Age population and the infrastructure on Lolland. The Iron Age open cultural landscape encompassed numerous settlements, richly furnished burials and fortifications, and has produced unique metal finds. The article presents a summary of investigation results. 相似文献

This article examines how basic socioeconomic and political factors are associated with higher levels of cooperation to garner a local community's shared green reputation. We analyze panel data on participation efforts in a collective voluntary environmental program, the Ecological Blue Flag Program, by the entire population of beach communities in Costa Rica between 2001 and 2009. Collective voluntary environmental programs are relatively new and aim to improve environmental performance and shared “green” reputation through joint participation and certification of multisector groups comprising businesses, governmental institutions, and nongovernmental organizations. Our results indicate that higher levels of within‐community cooperation for shared green reputation are more likely in seashore localities with lower income inequality and/or a higher number of businesses. These findings run counter to research suggesting these same characteristics are associated with lower levels of cooperation in the management of common pool natural resources such as fisheries and forests. We also find that within‐community cooperation is positively correlated with a greater proportion of expatriates from industrialized countries and/or with higher levels of democratic political participation. 相似文献

While the academic focus on Muslim women’s dress and comportment has enriched our understanding of the multifaceted formation of pious femininities, there has been much less consideration of the embodied practices of Muslim men. What work does exist on Middle Eastern men’s piety, sexuality, and everyday conduct too often falls back on established categories, such as traditional, Western, or Islamic identities. Yet it is crucial not only to critically examine how we conceptualize masculinity in the Middle East, but also to recognize the political and cultural importance of how masculinities are enacted through everyday practices. In this article, we argue that questions of dress and bodily practice are relevant to an understanding of how young devout Muslim men navigate the complex spatiality of piety, morality, and masculinity in contemporary urban Turkey. Drawing on fieldwork with young devout men in Konya and Istanbul, we illustrate how multiple, competing devout Muslim masculinities participate in the production of uneven moral geographies in these two very different Turkish cities. Further, we find that the possibility of different ways to enact devout masculinity opens questions about the universality of Islamic knowledge and practice. We suggest that the embodied construction and regulation of the looking-desiring nexus tethers male sexual desire to the public performance of Islamic morality. Our intervention is thus to demonstrate how different versions of masculinity and Islamic piety striate the moral geographies of these two Turkish cities, and thereby to further recognition of the contingency and plurality of both masculinity and Islam. 相似文献

ABSTRACTThis paper explores how global innovation networks (GIN) within multinational companies (MNCs) act as extra-regional sources for path development in a regional innovation system (RIS) specializing in the oil and gas sector. We combine the literature on intra-firm knowledge dynamics in MNCs’ GIN with the literature on RISs to better understand their interrelatedness and their dynamics. Based on interviews with 15 MNCs located in the south-west of Norway, we find that firms are highly dependent on competence throughout the MNCs’ entire networks, as well as interaction with the overall RIS. The findings expose that MNCs’ GINs can act as extra-regional sources for path ‘extension’ in thick and specialized RISs through intra-firm mobility, observation and sharing of routines and best practice, mainly resulting in incremental innovations. We find some signs of potential path ‘renewal’, including radical innovation ideas. However, there are hampering factors linked to strong internal competition for innovation projects, pressure for local profitability and ownership motivation. At the level of RISs, new initiatives going beyond existing cluster initiatives and specializations need support. 相似文献

Taking issue with how associations between technical prowess or entrepreneurship and masculinity tend to be taken for granted or are seen as stemming from natural or intrinsic gender differences, over the last two decades feminist scholars have developed theoretical approaches to understand the gendering of professions and abilities as the performative outcome of particular cultures and histories. We build on these insights to explore how associations between masculinities, technology and entrepreneurship shape ideas and practices of small-scale water provision in Maputo. Our findings show how activities (i.e. technical craftsmanship, hard physical work) or abilities (i.e. risk-taking, innovativeness) regarded as masculine tend to be considered the defining features of the profession. This shapes how men and women make sense of and talk about their work, each of them tactically emphasizing and performing those aspects best fitting their gender. Our detailed documentation of men’s and women’s everyday involvements in water provisioning challenges the existence of sharp boundaries and distinctions between genders and professional responsibilities. It shows that water provisioning requires many other types of work and skills and male and female household members collaborate and share their work. The strong normative-cultural associations between gender and water provisioning lead to a distinct under-recognition of women’s importance as water providers. We conclude that strategies to effectively support small-scale water businesses while creating more space and power for women involved in the business require the explicit recognition and re-conceptualization of water provisioning as a household business. 相似文献

When the Icelandic television series ‘Trapped’ was aired it instantly garnered worldwide attention. The main character, a rugged Icelandic man, is presented as being one with the harsh cold landscape. This article demonstrates how visual materials, like ‘Trapped,’ have become extremely important in the presentation of Iceland to the outside world, as well as working to present Iceland as a tourism destination. Furthermore, we evidence how ‘Trapped’ identifies with the Nordic noir genre. Our analysis shows that the series ‘Trapped’ and recent Icelandic films rest on the strong and entrenched association of Icelandicness with maleness, while also reflecting on existing stereotypes about Iceland and the Icelandic people as being exotic, both of which have become reanimated through the tourism industry. Thus, visual material such as ‘Trapped’ constitutes a part of, and becomes in and of itself symbolic of recurrent masculinity in Iceland. Our analysis emphasizes the importance of framing the ‘official’ production of locations as tourism destinations by both state and commercial industries in relation to other cultural productions that often also engage with mobile historical stereotyping and commercial attempts at nation branding. 相似文献

Salt crystallization in porous materials constitutes one of the major causes of decay of buildings/archaeological sites in a wide range of environments. Desalination is among the most common methodologies of conservative treatment for salt decay. However, classic desalination techniques might be not suitable for long-term conservation. During the past decade interest has been an increasing towards crystallization inhibitors as a new means of controlling crystallization damage. This study deals with the first in-field application of an environment-friendly inhibitor system— phosphocitrate (PC). In particular, the case study of the Roman mosaic of Orpheus and the Beasts in Perugia (Italy) is presented. The inhibitor is completely soluble in water or alcohol, non-toxic, and easy to apply, thus enabling its use in accordance with the volatile organic compounds emission control and safety during the conservation works. Relevant samples from control and treated mosaic areas were collected and analyzed comparatively by means of Fourier transform-infrared spectroscopy, scanning electron microscopy, and energy dispersive spectrometry to study the potential of the inhibitor system in preventing/controlling salt damage in such archaeological site. 相似文献
