交通路网中心性对土地利用强度的影响研究——以青岛市中心城区为例

采取青岛市交通路网矢量数据和 POI 数据，综合运用核密度估计法、地理加权回归模型和多中心性评价模型，从中心性角度解析了青岛市中心城区交通路网与土地利用强度的相关关系。研究表明：青岛市中心城区交通路网的临近中心性与直线中心性结构呈现“中心—外围”模式，中介中心性具有显著的点轴模式；商业、公共服务以及居住用地布局均呈现多中心结构；交通路网中心性与土地利用强度具有较强的相关性且相关关系具有空间异质性；商业用地和公共服务用地与交通路网中心性的相关性高于居住用地。研究揭示了交通路网与土地利用强度之间具有较强的依赖性，为城市规划提供可靠的理论依据，有助于进一步优化城市空间布局。     

‘The Conscience of the Community’: the Au Vaine of Rarotonga

ABSTRACT

The Au Vaine (‘several women’ in Cook Islands Māori), grassroots women’s committees, worked to promote agricultural efforts and food security in Rarotonga during the 1920s and 1930s. A unique organization, the Au Vaine actively encouraged the growing of commercial crops alongside subsistence plantings at a time when women were being pushed towards the home and hearth, and men pulled to wage labour jobs. These women illustrate the powerful and often unheard voices Pacific women retained throughout this period, as well as the critical role of food in Pacific history. In this article I examine the context within which the Au Vaine emerged, discuss what distinguished them from other women’s committees in Polynesia, highlight their purpose and impact on Cook Islands foodways, and explore some of the reasons they declined by the 1940s.     

Late quaternary alluviation and soil formation in the southern Argolid: its history,causes and archaeological implications

In the context of an archaeological survey of the southern Argolid, Greece, studies have been carried out to elucidate the evolution of the landscape since its earliest known human occupation about 50,000 years ago. One of these studies was a detailed geological mapping of the late Quaternary alluvium and soils in the area. Dated by means of thorium-uranium disequilibria, archaeological finds, and historical information, seven periods of alluviation were identified, each of short duration relative to long intervening periods of stability and soil formation. The three earliest alluvial phases, falling before and during the last glacial interval, range from about 330,000 to 32,000 years in age. No alluviation accompanied the last glacial maximum around 20,000 years ago. In fact, a stable landscape persisted until about 4500 years ago, when debris flows and widespread aggradation in the valleys resulted from major slope destabilization and soil erosion, probably as a result of extensive land clearance in the Early Bronze Age. A subsequent stable period lasted through the many upheavals of the later Bronze Age, the Dark Ages, and the early historical period. It came to an end with a brief phase of alluviation between about 300 and 50 BC. Stability returned through the late Roman period, notwithstanding considerable expansion of the settled area. Another period of destabilization, this one marked by debris flows and hence major soil erosion, is poorly fixed in time, but probably coincides with expanded maquis clearance accompanying the resettlement of the area around AD 1000. Subsequent events of soil erosion and aggradation vary in nature and timing from one drainage to the next and, in some areas, continue today.Nature and chronology of the soil forming and alluviation events show that simple correlations with climatic events do not suffice to explain them. For the latter ones, past about 2500 BC, human activity seems to be the dominant cause, but once again the relation between cause and effect is not straightforward. Land clearing, or neglect of soil conservation efforts during economic downturns, appear to have a more devastating effect upon the landscape than do intensive land use or total land abandonment.     

Sourcing of sanukite implements by X-ray fluorescence analysis II

Non-destructive analysis of sanukite stones of known source and sanukite implements was carried out by means of energy-dispersive X-ray fluorescence spectrometry. Attention was focussed on areas in middle-western Japan. Stone taken from four source districts was classified into nine different groups. More than a hundred implements obtained from thirty-six archaeological sites were allocated to their sources by means of Hotelling's T² test.     

Kant and the Two Principles of Publicity

ABSTRACT

The aim of this article is to argue that the principle of “publicity” constitutes a fundamental idea in Kant’s political thought. Publicity provides a central insight that binds together various strands of Kant’s political writings (on issues as diverse as the question of Enlightenment, the right of revolution, historical teleology, reflective judgment, cosmopolitan citizenship, democratic peace, and republican government), and moreover, it offers a much-needed cornerstone for a systematic exposition of his nonexistent political philosophy. Apart from some eminent examples, publicity has been a rather neglected topic in the ever-expanding literature on Kant’s political ideas. Revisiting this notion will make us more attentive to his evocation of the “spirit of republicanism” over and above the letter of the law, and might prompt us to reconsider Kant’s reputation as a classical representative of liberal political thought. Indeed, it should inspire us to situate Kant’s appeal for the “public use of reason” in the vicinity of the republican ideal of political liberty.     

Assessing Protocols for Identifying Pacific Island Archaeological Fish Remains: The Contribution of Vertebrae

Three fish bone identification protocols used for determining taxa composition for Pacific island archaeofaunal assemblages are evaluated. The protocols include using the following: (1) the most commonly identified five paired cranial bones and ‘specials’ or unique elements; (2) an expanded number of cranial bones; and (3) the less common inclusion of all vertebrae. Explicit identification and quantification protocols are outlined for systematically incorporating all vertebrae which, predictably, increases the number of identified specimens for an assemblage, thus providing more bones useful for reconstructing live fish biomass (weight and length). Significantly, a range of unique archaeological vertebrae are useful for calculating minimum number of individuals. Using a well‐preserved assemblage from Henderson Island, Pitcairn Group, southeast Polynesia, numbering 6480 fish bones (concentration index = 21 580 m³), we demonstrate differences in rank‐order abundance from three taxon identification protocols. For example, when using all vertebrae grouper (Serranidae) and surgeonfishes (Acanthuridae) are more numerically equivalent than when relying mostly on cranial bones for identification for minimum number of individuals and number of identified specimens. This has important implications for making comparisons between sites or across regions where different identification protocols were used. This pilot study demonstrates that using all vertebrae for taxon identification and quantification, not just unique hypurals (terminal vertebrae) or those from sharks and rays (Elasmobranchii), should be standard practice for identifying a greater number of bones to taxon and thereby providing better reconstructions of prehistoric fishing and subsistence practices in the Pacific.

Playing,parenting and family leisure in parks: exploring emotional geographies of families in Guangzhou Children’s Park,China

ABSTRACT

Children’s leisure activities in parks have attracted increasing scholarly interest in recent decades. However, relatively little attention has been given to the emotional needs and responses of children to their activities within a park’s play spaces. Moreover, what parents perceive, and how they themselves engage within children’s playing spaces, is under-studied. Drawing on fieldwork carried out in the Guangzhou Children’s Park, China, this paper aims to explore the experiences of both children and parents within this particular playing space. Supplementing participant observations with interviews and analysis of reviews on the Internet, the paper finds that children obtain a sense of family and company from their parents’ presence, and parents recall memories of their own childhood and obtain emotional recovery by visiting parks with their children. The findings suggest that play spaces are not only places where children play, but also where family life and childhood are ‘built’. The paper contributes to the existing literature by highlighting and examining the ‘child–parent’ relationship within playing spaces. By conducting a case study of a non-Western society, the paper encourages researchers to examine ‘child–parent’ relationships in a family leisure context, and to explore the everyday and emotional geographies of family life in contemporary China.
