复杂情境中的日常活动可视化与应用研究

时间地理学以时空路径为代表的符号系统由于具备抽象、简明、直观等特点,在地理学及其他社会科学领域得到了广泛传播与应用。随着GIS与地理可视化技术的不断进步、高精度时空行为数据的批量生产等,真实地理环境中个体时空运动轨迹的三维可视化技术也在不断进步。信息化社会的到来与城市社会转型等使得现代社会中的人类日常活动变得十分复杂,时间地理学由于直观刻画时空间中人类活动的时空连续性与复杂情境性而备受关注。本文首先界定了人类日常活动复杂情境的分析维度,包括日常情境、企划情境、地理情境、社会情境、技术情境等,并在此基础上将绝对时空间坐标系下的时空路径拓展到相对时空观下多维活动序列的可视化表达。其次,简单说明Daily life与VISUAL-Time PAc TS/energy use等可视化工具,介绍时空路径在复杂情境性下的可视化、模式挖掘及个案分析。最后,案例分析个体与群体尺度上活动情境可视化方法在家庭成员间分工与互动、日常活动模式差异与家庭能源消耗差异等方面的应用。     

Changes in children's nature-based experiences near home: from spontaneous play to adult-controlled,planned and organised activities

A qualitative case study from Brumunddalen, Norway, indicates that children's use of nature areas near their homes have changed substantially from being spontaneous and self-initiated to being part of planned, organised and adult-controlled activities. This study explores the association between changes in outdoor play and wider patterns of change in childhood today, as increasing amounts of play time is spent in institutions and organised activities, or occupied by computer and internet usage. The paper discusses these effects in terms of social relations as well as children's identity formation. The subject was investigated through adults' memories of their own childhood and their observations of children's practices.     

Whetstone Typology: Or the First Shipwreck of Turid Fiskarbekk and Marine Archaeologists Who Had to Think Again

Finds from the Viking period, the middle ages and from more recent historical trading places and towns in northern Europe show that the export of whetstones from Eidsborg in the Telemark district of southern Norway has a history of more than 1,000 years. The water-based route from the quarry area, 600 m above sea level, to the nearest shipping port consists of 120 km of lakes, rivers and portages. This article takes up the export history in the light of a recently discovered cargo of whetstones found in Flåvann, Telemark. The history of the recovery of the find shows that the cargo examined most probably leads to an incident in the 1820s and, to a woman named Turid Fiskarbekk. The find leads to a wider perspective, more specific to the life of Turid Fiskarbekk. Therefore the article presents a side-story about her, where the intention is to show how integrating a gender perspective in maritime archaeology makes new knowledge possible.     

The influence of different tempers on the composition of pottery

The modification of the raw clay by the potter to produce a paste suitable for the intended purposes adds a layer of obfuscation to the problem of provenancing the original clay source by chemical fingerprinting. By preparing different pastes from the same commercially available raw clay and their chemical analysis by Instrumental Neutron Activation Analysis, an experiment under controlled conditions (tempers, mixing ratios, firing temperatures and sampling methods) sheds light on the influence of different tempers.     

The extent of farm desertion in central Sweden during the late medieval agrarian crisis: landscape as a source

The effects of medieval agrarian crisis on settlement and population were considered in a major interdisciplinary research project in Scandinavia during the 1960s and 1970s. Within this project, there were significant differences in methods used to calculate the extent of farm desertion between historians in the participating countries. The reliance on written source material within the Swedish team reflected the dominant approach amongst historians who made less use of map and landscape evidence than others. In this renewed investigation of the magnitude of farm desertion in the Late Middle Ages, focussing on the province of Jämtland in central Sweden, field survey of the physical landscape and some three thousand historical maps are used as evidence, alongside conventional written sources, such as official letters and taxation documents. The results indicate that the extent of farm desertion in medieval Sweden has been underestimated because Swedish scholars generally eschewed the use of the retrogressive method, which their Norwegian counterparts had been using since the 1940s. There is therefore good reason to reassess the desertion rates of medieval farms in other parts of Sweden as well, using traditional geographical source materials together with the documentary sources usually favoured by historians This may also hold for other parts of Europe as well. The rate of desertion is discussed in a wider context of settlement contraction and expansion in central and peripheral areas of Sweden, including the long drawn-out process of reclamation of the deserted farms (ödesbölen).     

THE LOGIC OF THE CONSTRUCTION OF RURAL POLITICS: POLITICAL DISCOURSES ON RURALITY IN NORWAY

Two competing discourses emerge from a careful reading of parliamentary debates in Norway on rural development. One regards rural values as intrinsic, while the other regards the rural as an actor in a play about economic growth. The 'growth' discourse has economic growth as its nodal point and fo-cuses on the freedom of an individual to establish a business wherever he or she wishes, and to migrate to any preferred destination. The 'intrinsic value' discourse places the value of rural settlements and cultures as its nodal point and focuses on allegedly forced migration, a nature-based economy, and local freedom of action. During the neoliberal period, starting about 1980 the strength of the intrinsic value discourse has been increasingly displaced by the growth discourse. The latter seems to match general social changes such as neoliberalism and globalization more than the former. However, analysing the fight between these two discourses is not exhaustive. A broader analytic perspective is needed if we want to understand the logic of how the meaning of rurality comes about. The meaning of rurality in Norwegian politics is made through the way the competing discourses link up to 'nondiscursive' topics that originate and evolve outside the discourses on Norwegian rural politics. We claim that topics which include economic safety and national identity/nation-state are more or less fundamental to understanding the logic of the production of the concrete discourses of rurality in Norwegian politics. We provide evidence that rural change is contingent not only on the meaning-making process in parliamentary debates, but on the way truth claims made by politicians are linked to general national and global issues.
