Intervention publique sur le développement de grappes industrielles au Québec

This article describes the conditions for the development of four industrial clusters and the mechanisms of their integration in the regional economy. The case studies are the aerospace and apparel clusters in Montreal, and the agri‐food and marine science and technology clusters in the Lower St. Lawrence region. Clusters are defined as arrangements of businesses, government actors, public authorities, and local intermediary organizations in a local area. However, the study shows that clusters are based on actors and processes operating at different scales, from the local to the global. It also shows the importance of the sectoral leadership acknowledged by the different stakeholders.     

唐五代时期海洋灾害成因探析

海洋灾害是唐五代时期较为严重的自然灾害之一,主要是由历史时期海洋气候、海面波动、海水侵蚀等自然因素引起,同时又与当时特定的社会背景有一定的关联。如唐五代时期沿海人口的增加、濒海城市增多与海洋防灾技术的不成熟,导致受灾损失加剧;沿海政府组织的大规模屯田,破坏了沿海地区固有的生态景观,增加了唐五代时期海洋灾害的发生频率。

H. L. Hunley Revealed: documentation,deconcretion, and recent developments in the investigation of an American Civil War submarine from 1864

Since 2014, the conservation staff at Clemson University's Warren Lasch Conservation Center in Charleston, South Carolina have been removing the concretion from the hull of H. L. Hunley, an American Civil War submarine lost 1864. In parallel, the archaeological team has been documenting the condition of the hull, the concretion layers, and the hull features revealed by the deconcretion process. This involved photography, direct measurements, and 3D scanning. This article will discuss the strategy for recording the concretion, the techniques used to document the newly revealed hull and its unique features, and the preliminary analysis of their archaeological significance.     

The Odyssey Case: press,public opinion and future policy

The Odyssey Case refers to the dispute between Odyssey Marine Exploration Inc. (OME) and the Kingdom of Spain in the US courts to determine the ownership of more than 500,000 coins, as well as other artefacts, that OME recovered from a wreck‐site it had code‐named Black Swan. However, the process was much more than a dispute over the coins. It reflected many of the components involved in the protection of underwater archaeological heritage, especially when economic and political interests are at stake. Written from the perspective of an archaeologist working for the regional authority responsible for developing archaeological policy, this paper tries to assess the case's impact on future policy development.     

Intertidal Foraging on Atolls: Prehistoric Forager Decision-Making at Ebon Atoll,Marshall Islands

Prehistoric molluscan assemblages provide insights into long-term patterns of human landscape use, environmental change, and human impacts to marine resources. The investigation of forager decision-making regarding the selection of certain mollusc taxa and/or the exploitation of particular habitats is fundamental to understanding human-environment interactions in the past, and is relevant for understanding trajectories of human impacts to the intertidal zone in coastal settings. We document variability in the collection of molluscs at two archaeological sites on Ebon Atoll, Republic of the Marshall Islands: one on a windward, intermittently occupied islet, and the other on a permanently inhabited leeward islet. All molluscan taxa were assigned to a range of habitats within a hierarchical classification scheme for intertidal marine environments. The relative abundance of taxa from each habitat was used as a proxy for forager decision-making. We report a generalized, non-selective, foraging strategy focused on gastropod taxa from the high intertidal and supratidal. These results indicate that rather than focusing intensively on select taxa, intertidal foragers targeted particular marine habitats, taking advantage of the predictable behaviors of the molluscs that inhabit them.     

Coastal Feasts: A Pleistocene Antiquity for Resource Abundance in the Maritime Deserts of North West Australia?

ABSTRACT

Located on the edge of Australia's North West continental shelf, Barrow Island is uniquely located to address a number of research questions, such as the antiquity and changing nature of Indigenous occupation, including shifting uses of regional economic resources in response to post-glacial sea-level rise. These questions are addressed from a range of archaeological, zooarchaeological, and geoarchaeological disciplines. Although only preliminary, results to date indicate the presence of marine resources dating to before sea-level stabilization (～ 7.5 ka) that contain both dietary and utilitarian species, including high-ranked species such as sea turtle. The marine assemblages reflect a variety of habitats and substrates with a 17,000-year record for the presence of a former tidal marsh or estuary. We also note recently obtained ¹⁴C and OSL dates that extend the dietary marine faunas and initial occupation to well before 41 ka. This demonstrates that consumption of coastal resources began prior to the Holocene, when we begin to observe more widespread evidence of marine resource exploitation in the broader Canarvon Bioregion of northwest Australia. This evidence supports arguments for further research to directly test both the productivity of, and human reliance on, marine habitats from initial occupation.     

城乡融合发展视野下山西乡村振兴路径探索

城乡融合发展是实现乡村振兴的基本方向。在当前推动乡村振兴发展实现农业农村现代化的重要时期,深入探究城乡融合发展与乡村振兴二者之间的关系,有助于更准确地探索乡村振兴路径。本文基于人地关系地域系统理论、人与自然之间物质变换思想以及城乡融合发展思想,结合山西乡村振兴实践面临的困境,对乡村振兴微观路径进行探索。研究结果表明:城乡融合发展是城乡地域系统人地关系协调可持续的重要驱动因素。从人才、文化、组织、产业、生态等方面探索制度和各类要素的城乡融合发展具体路径,调整乡域系统人地关系以适应经济社会发展进程,可以为当前乡村振兴战略实施提供理论参考。     

Heritage views through urban exploration: the case of ‘Abandoned Berlin’

This article frames the practice of urban exploration and its interest towards abandoned places from a heritage perspective. It is argued that most urban explorers prioritise the excitement of trespassing and the creation of their own narratives over the historic importance of the sites they explore. These ‘performative’ explorers avoid deliberate attention that may lead to vandalism or touristification – an alternative way of ‘preserving by not preserving’ that celebrates decay and assumes the sites’ progressive loss. To achieve this, they prefer not to disclose exact locations, creating a divergence towards a minority of practitioners who prefer to collect data on history and current state of conservation to make it public. Attention is paid to these ‘communicative’ explorers, whose documentation renders abandoned places visible, opening further debates about a more inclusive preservation and memorialisation. By distinguishing both heritage views, the objective of this article is to contribute to the enlargement of Heritage Studies by incorporating urban exploration as a space for reflection between loss and bottom-up preservation and interpretation.     

Archaeological Assessment of Second World War Anti‐Torpedo Close Protection Pontoons in Scapa Flow,Orkney

This paper presents the outcomes of sidescan sonar and archaeological diving surveys in 2015 of two wrecked vessels located off Flotta Island, Orkney, North Scotland. Archival research indicates these are the remains of Anti‐Torpedo Close Protection Pontoons (ATCPP), an experimental protection device used for close protection of naval vessels at anchor in Scapa Flow from attack by aircraft‐launch torpedoes. The pontoons were only in operation in Scapa Flow for 13 months (March 1941–April 1942) and few were brought into service. As such they represent a rare heritage resource, for which very little is known about their operation.
