基于交通流的关中城市群城际交互对城市空间增长的影响

流动空间背景下,探讨城际交互对城市群城市空间联动增长的影响对有效调控城市空间增长,促进城镇化可持续发展具有重要意义。本文以西部关中城市群为例,基于土地利用和城际交通出行大数据,系统分析了以城际出行表征的城际交互对关中城市群城市空间联动增长的影响。结果表明：(1)关中城市群城际交通出行空间组织呈现出以西安为核心,咸阳、渭南、宝鸡为次级节点的组织格局。(2)2010年以来,关中城市群城市空间规模迅速增加,八年间共增长1398.80 km²,年均增长174.85 km²,空间上主要集中于西安、咸阳和运城等地;西安是城市群城市空间增长的首要贡献者,在2010—2015年、2015—2018年间占比分别高达36.04%和34.70%。(3)与沿海发达地区类似,以城际交通出行表征的城际交互同样对西部关中城市群的城市空间增长呈现出逐步增强的正向驱动作用,第二阶段(2015—2018)解释贡献率显著高于第一时段(2010—2015),分别为7.54%和5.50%。     

旅游跨文化学习中的主客互动——阳朔太极拳的教与学

中国传统文化的传播对于实现文化自信具有重要意义。本文关注了近年火热的“外国人赴阳朔学太极”现象，综合运用非参与式观察法、深度访谈法与文本分析法，以“身体符号”的意义变迁为研究脉络，探讨“外国人学太极”这一跨文化情境下的主客互动活动，分析外国人赴阳朔学太极的动因、互动过程与内在机制。研究发现：从互动媒介来看，身体作为符号在跨文化情境中发挥着重要的媒介作用，身体符号的意义也在跨文化互动中逐渐深化；从互动过程来看，不同主体的角色和观念以身体符号为媒介在跨文化互动中实现交互协商，由此加深主体对于自我的认知。人与人之间的学习型紧密联结强化了人与地方之间的关系。     

CULTURE‐LED DEVELOPMENT AND CONFLICT OVER URBAN SPACE: REIMAG(IN)ING ST PETERSBURG,RUSSIA

Culture‐led projects have long been part of strategies to regenerate cities in advanced capitalist economies. In recent decades those projects also have become a focal point of urban development in post‐socialist cities. This study argues that an attempt to reimage(in)e the city of St Petersburg through its culture‐led flagship project, Mariinsky Theatre–2, has generated significant changes not only to its built fabric, but also to its social fabric. In the context of a post‐socialist city, this study examines how the urban space of the historical centre is being contested by its urban users, often on the basis of differences in perception, including the impacts of the culture‐led project on those perceptions. Civic awareness about social exclusion and inclusion in urban space is on the rise in this post‐socialist city.     

CHORA IN CURRENT GEOGRAPHICAL THOUGHT: PLACES OF CO‐DESIGN AND RE‐MEMBERING

Reading places is integrally linked to geographical studies. One of the oldest Western formulations of place is chora, which was introduced in Plato's Timaeus and has thereafter contributed to a rich tradition of interpretations. The geographical interest in chora has gradually increased as it has proven its value in making sense of the flowing conditions of contemporary social change. The gradual turn towards chora is also due to intense methodological rethinking in geography during recent decades. This article discusses the latest formulations of the geographies of chora, and focuses especially on the interpretations inspired by Jacques Derrida and Julia Kristeva. Their formulations of chora, including succeeding critiques, have encouraged us to rethink places of co‐design and re‐membering as illustrations of the paradoxes of chora as a ‘place in‐between’.     

乡村旅游地空间生产与村民角色转型的过程与机制——以丹霞山瑶塘村为例

乡村旅游空间与村民社会角色是一个相互形塑和建构的过程,揭示两者的互动机制对乡村旅游地可持续发展具有重要意义。研究发现,乡村旅游地空间经历了农业生产空间、农旅并存空间、旅游消费空间的演变过程;村民角色从"农业生产者",经不同转型轨迹,归于"旅游从业者"角色。权力、资本和市场等主体对乡村旅游空间的建构,对村民角色扮演提出新的期望和规范;村民主体的微观权力、资本积累、个人技能、个人观念影响其角色扮演与空间适应;不同角色村民主体通过微观空间生产行为,促使乡村旅游空间景观化、商业化和制度化,也会产生民宿空间分异和乡村公共空间侵占等问题。     

URBAN NETWORKS AND GOVERNANCE IN CITY‐REGION PLANNING: STATE‐LED REGION BUILDING IN NANJING CITY‐REGION,CHINA

During the transition towards a more market‐oriented economy and entrepreneurial governance, local authorities have attempted to create new cross‐jurisdiction regional entities to enhance their competitiveness through making city‐region plans or regional strategic plans in China. This article analyses the process of region building in China through a case study of Nanjing city‐region. We argue that region building is a state‐led regional project in China, not a spontaneous process. City‐region planning has played a legitimacy‐seeking role in the construction of new regions. Based on the discourse provided by the city‐region plan, associated city networks are being created as a mechanism for plan implementation and regional coordination. This signals that regional planning is entering the stage of regional institution building. By assessing the capacity of regional institutions, we argue that the newly‐emerged regional institutions or urban networks have facilitated regionalization in terms of the increasing involvement of non‐state actors, the formation of regional coherence and identity and the enhanced inter‐city co‐operation. However, it is still difficult to establish effective regional governance due to competing local governments, the arbitrary political leadership and the fragmented planning functions.     

RURAL–URBAN SPATIAL INTERACTION IN THE GLOBAL SOUTH: LONG‐DISTANCE MOBILITY CHANGES,DESIRES AND RESTRICTIONS OVER TWO DECADES IN RURAL PHILIPPINES

The spatial interaction between rural and urban areas is intense in the Global South. While research into how this interaction influences livelihood opportunities is extensive, longitudinal identification and analysis of rural people's long‐distance mobility is rudimentary. This is problematic given the possible repercussions of a greater flow of people for transport system management (congestion, emissions, investments, social exclusion, etc.). Based on longitudinal survey data from 1990 to 2008/2009, this article addresses this gap by exploring how the long‐distance mobility behaviour of households and individuals has changed over a period of intensified rural–urban interaction in a rural Philippine area. The article furthermore addresses the individuals' mobility desires and restrictions related to long‐distance travel. The results indicate that both accessibility effects and effects related to information and communication technology (ICT), concentration of activities and opportunities towards major cities, age, labour market, and economic situation. Over time, particularly since improved accessibility conditions have enabled much faster travelling, more people have come to travel more frequently (although a suppressed demand is still present and inequalities are considerable) to more distant destinations, major cities in particular, for mainly social motives. A recent countertrend is evident, partly arising from mobile phones replacing physical movement. The increase in private vehicle ownership has so far been slow, so modal choice is still highly sustainable. Overall, the findings support core ideas derived from the new economic geography, but also notes, with earlier studies in transport geography, that travel time is a prime consideration.     

IDENTITIES AND URBAN SOCIAL SPACES IN LITTLE TOKYO,LOS ANGELES: JAPANESE AMERICANS IN TWO ETHNO‐SPIRITUAL COMMUNITIES

Ethnic identities are expressed and articulated in particular places. These mutable identities are crucial sources of meaning in the lives of social actors. This article seeks to elucidate just how the contexts of specific institutions in an urban enclave will impact upon patterns of conflict and cooperation among different subgroups practising two religious traditions. Historical discourses of ethnic community and ‘race’, shifts in migration patterns and the changing nature of the Little Tokyo enclave provide the formative patterns of social spaces, in which ethnic actors seek to create lives of spiritual and material meaning and security. Barth's concept of the social organization of cultural difference encourages analysis of ethnic identities as a dynamic and mutable enterprise. Because the maintenance of boundaries is crucial to identities, the manner in which a group seeks to maintain difference is intermeshed with the social terrain of particular places. Through qualitative methods of semi‐structured and informal interviews and participant observations, this project engages Japanese American identities within the context of two religious communities in an urban enclave. Fieldwork was conducted in two institutions, a Protestant church and a Buddhist temple, with the aim of exploring how Japanese American identities are expressed and (re)negotiated within different ethno‐spiritual communities. Such communities are fundamental to the expression of ethnic identities, and to the emotional lives of worshippers, particularly seniors and new immigrants.     

IN SEARCH OF NEW TIMES: TEMPORALITY IN THE ENLIGHTENMENT AND COUNTER‐ENLIGHTENMENT

Isaiah Berlin and other representatives of historicism have made the Enlightenment and the Counter‐Enlightenment into opposite cultures. The Counter‐Enlightenment is a criticism of the Enlightenment from within, so in many respects they overlap. However, with regard to perceptions of time they contradict each other. The times of the Enlightenment lean heavily toward chronology and can be labeled as “empty,” whereas the time perceptions of the Counter‐Enlightenment can be called “incarnated” and are identical with historical times. As a consequence the differences between the two temporalities lead necessarily to differences in synchronization.     

IN THE FOLDS OF TIME: RASHĪD AL‐DĪN ON THEORIES OF HISTORICITY

By focusing on Rashīd al‐Dīn's (d. 718/1318) historiographical oeuvre and here in particular his “History of the World,” this article challenges the usual approach to his Jāmi? al‐tawārīkh (Compendium of Chronicles) and argues that his was a deeply pluralistic enterprise in a world with many centers, tremendous demographic change, high social mobility, and constantly shifting truth‐claims in an ever expanding cosmos, to which Rashīd al‐Dīn's method, language, and the shape of his history were perfectly adaptable. This article introduces the notion of “parallel pasts” to account for Rashīd al‐Dīn's method. By placing the Jāmi? al‐tawārīkh and its author in their historical and intellectual context, this article also argues that this method is not restricted to Rashīd al‐Dīn's historiography: His historiographical work ought to be seen as part of his larger theological and philosophical oeuvre into which the author placed it consciously and explicitly, an oeuvre that is, like Rashīd al‐Dīn's historiography, pluralist at heart, and that could be as easily classified as “theology” or “philosophy” as “historiography.”     

REGION‐BUILDING IN THE ARCTIC PERIPHERY: THE DISCURSIVE CONSTRUCTION OF A PETROLEUM REGION

As social communities, regions are built through discourses that convey images of what the region is. Regions are built for a variety of reasons, including political and economic ones. This implies that changing economic circumstances have the potential to change the discourses on regional identities. Petroleum discoveries represent such a potential change in the economic circumstances of a region. This study of an emerging petroleum region in the north of Norway shows that a regional identity discourse is used to claim ownership over the petroleum resources in the Barents Sea in order to justify the need for a production plan that maximizes regional economic benefits. In this way, the discovery of petroleum represents an opportunity to reinforce regional identities around a set of common interests. However, “the region” is vaguely defined in this discourse, being used in reference to two different scales: Finnmark and Northern Norway.     

ORTHOIMAGE‐BASED DOCUMENTATION OF ARCHAEOLOGICAL STRUCTURES: THE CASE OF A MEDIAEVAL WALL IN PONTEVEDRA,SPAIN

During the completion of the expansion works at the Museum of Pontevedra (Spain), a stretch of about 60 m of the medieval walled enclosure surrounding the historic city centre was discovered. Due to its value as a heritage element, the discovery of this archaeological structure required the implementation of preservation activities and exhaustive documentation so that future generations will be able to know and enjoy this piece of history. This paper presents digital models that reproduce the original structure of the wall using close‐range digital photogrammetry, as well as orthophotos, which thoroughly document the dimensional and textural characteristics of the archaeological site. In addition to analysing the accuracy and validity of photogrammetry in the conservation of archaeological heritage, a methodology of data capture, processing and photogrammetry representation is evaluated.     

UNIQUE PRE‐ROMANESQUE MURALS IN KOSTOĽANY POD TRÍBEČOM,SLOVAKIA: THE PAINTING TECHNIQUE AND CAUSES OF DAMAGE

Pre‐Romanesque murals at Kosto?any pod Tríbe?om, Slovakia, have been investigated by portable X‐ray fluorescence and by microanalytical methods to identify painting materials (pigments and binders), and to explain the degradation of colours. Today, missing green and blue shades have been reconstructed according to residual concentrations of Cu, which correspond to copper chlorides—products of salt corrosion of the copper carbonates azurite and/or malachite, accelerated by micro‐organisms. As confirmed by powder X‐ray microdiffraction, original minium (Pb₃O₄) has been transformed to brown–black plattnerite (PbO₂). In increased humidity, even insoluble pigments are washing down from the walls and the intensity of colours further diminishes.     

NEIGHBOURHOOD ETHNIC MIX AND THE FORMATION OF MIXED‐ETHNIC UNIONS IN BRITAIN: A LONGITUDINAL ANALYSIS

Although developed societies are becoming increasingly ethnically diverse, relatively little research has been conducted on geographies of mixed‐ethnic unions (married or cohabiting). There is some recent evidence from the US that mixed‐ethnic couples are more likely to be found in mixed‐ethnic neighbourhoods, but this research is based on cross‐sectional data. Therefore it is not possible to determine whether mixed‐ethnic couples are more likely to form in mixed‐ethnic neighbourhoods or whether they are more likely to move there. Our longitudinal analysis allows us to tease out the relative importance of these two processes, furthering our understanding of the formation of mixed‐ethnic unions. Using data from the Office for National Statistics Longitudinal Study we examine neighbourhood effects on the formation of mixed‐ethnic unions in England and Wales. We find that mixed‐ethnic unions are more likely to form in neighbourhoods with low concentrations of co‐ethnic population. The results from this study lend support to the contact theory that geographical proximity to other ethnic groups enhances mutual understanding between people from different ethnic groups and could lead to the development of intimate partnerships.     

EMBEDDED AND DISEMBEDDED PRACTICE IN THE FIRM–PLACE NEXUS: A STUDY OF TWO WORLD‐LEADING MANUFACTURERS OF SKI EQUIPMENT IN THE LILLEHAMMER SKI CLUSTER

Studies of agglomerations and clusters in economic geography anticipate strong interdependency between firms and places. However, despite the extensive literature, we lack a coherent micro‐theoretical foundation. The relationship between the rationales and practices of firms remains somewhat unspecified. In this article, we analyse the diversity of rationales and practices in a firm–place nexus. Possible rationales for firm practice are outlined, examining the assumptions of three, main theoretical perspectives in economic geography. This microeconomic approach is applied through an analysis of the two key firms in the Lillehammer skiing industry cluster in Norway. The study contributes to a more nuanced understanding of how the agency of firms influence and are influenced by co‐location.     

COORDINATING EVERYDAY LIFE IN THE NETHERLANDS: A HOLISTIC QUANTITATIVE APPROACH TO THE ANALYSIS OF ICT‐RELATED AND OTHER WORK‐LIFE BALANCE STRATEGIES

Due to women's increased participation in the labour force, more and more family‐households are now juggling paid labour and care‐giving in space and time and do so in many different ways. Much research and policy about how households try to establish a satisfactory work‐life balance singles out particular coping strategies, such as telecommuting or the mobilizing of informal help by relatives or friends. While insightful, foregrounding single strategies may oversimplify the complex reality of everyday life, in which people often skilfully weave together multiple coping strategies. As well, advances in information and communication technologies (ICTs) have further diversified the arsenal of possible coping strategies, but the academic literature has yet to verify whether ICT usage complements or substitutes the adoption of other coping strategies. Adopting a holistic quantitative approach this study assesses which combinations of coping strategies prevail and which role ICTs play in this regard among one‐ and dual‐earner households in the Utrecht–Amersfoort–Hilversum area of the Netherlands. We also examine systematic variations in strategy combination by socio‐demographics, ICT possession, affordability and skills, social network factors, employment and commute factors, spatial factors, lifestyle orientation and other factors. We identify several distinct combinations of strategies and find that ICT‐related strategies are frequently adopted by highly educated employed parents in the Netherlands attempting to achieve a satisfying work‐life balance and tend to complement other types of strategies. Which combinations of strategies have been adopted depends most strongly on the presence of young children, but also on employment factors and characteristics of the environment surrounding the dwelling and main workplace.     

MEAN SHIFT: A NON‐PARAMETRIC ALGORITHM FOR THE SEGMENTATION OF ANOMALIES IN GEOPHYSICAL IMAGES OBTAINED FROM MAGNETIC PROSPECTION DATA

This paper studies the applicability of the Mean Shift algorithm as support in interpreting geophysical images produced, on this occasion, from magnetic prospection data. The data obtained from a magnetic survey carried out in Gilena (Seville province, Spain) by the La Rábida Archaeophysics Group will be used for the research. Its applicability is illustrated by comparing, on the one hand, some reduction‐to‐pole algorithms and on the other, the (well‐known) k‐means algorithm. Finally, the paper shows the results obtained by applying the Mean Shift algorithm as an alternative method to ‘unsupervised clustering’ of anomalies that appear in images obtained from geophysical data, in which the a priori knowledge of the number of classes is difficult or impossible.     

FROM RAW IRON TO SEMI‐PRODUCT: QUALITY AND CIRCULATION OF MATERIALS DURING THE IRON AGE IN FRANCE*

Iron raw materials provide a privileged source of information for the reconstruction of metallurgical techniques and the circulation of iron products. An interdisciplinary approach, combining archaeological and archaeometrical studies of the exemplars known from the French Iron Age, has been undertaken. This enables a new typological classification to be produced that demonstrates a correlation between morphological and structural properties. Through comparison with chronological data, it is possible to propose a reconstruction of the organization of production according to three main periods, which are characterized by the circulation of different qualities of iron and by diverse levels of artisanal specialization.     

CONSTRUCTING CARIBBEAN CHRONOLOGIES: COMPARATIVE RADIOCARBON DATING OF SHELL AND WOOD ARTEFACTS FROM PRE‐COLUMBIAN SITES IN CUBA

The lack of robust chronological frameworks for pre‐Columbian archaeology in the Caribbean limits the interpretive potential of ongoing studies of inter‐site and inter‐island interaction. This paper reviews the dating of 28 wood and shell artefacts from sites in northern Cuba in an attempt to date pre‐Columbian activity in the region and develop dating methodologies for the study of pre‐Columbian interaction in the Caribbean. This research compares dates from wood and shell artefacts from the waterlogged site of Los Buchillones in north‐central Cuba with dates from shell artefacts from sites on eight islands in the Sabana–Camaguey archipelago in the Bahama Channel. In addition to providing a chronological framework based on absolute dates for pre‐Columbian activity in northern Cuba, this paper also considers the methodological issues of using shell for dating pre‐Columbian activity in the Caribbean.     

ARTIFICIAL OR NATURAL ORIGIN OF HEMATITE‐BASED RED PIGMENTS IN ARCHAEOLOGICAL CONTEXTS: THE CASE OF RIPARO DALMERI (TRENTO,ITALY)

This study concerns those crystallographic and microstructural features that can provide indications on the actual origin of red pigments based on hematite (Fe₂O₃). The main features of natural and artificial hematite are recalled and used to discuss the results obtained from the characterization of red‐ochre samples coming from the Palaeolithic site of Riparo Dalmeri, a rock‐shelter located in northeastern Italy, dated to 13 000 cal. bp , and notorious for the presence, among the other finds, of red‐painted calcareous stones. Painting and the treatment of leather and hides obtained from the intensive hunting activity were the main uses of the hematite‐based red‐ochres at Riparo Dalmeri. It turns out that hematite was mostly obtained from the thermal treatment of goethite, which, unlike hematite, was and still is widely available in the neighbourhood of the site.
