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 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.     

Creativity,Culture and Urban Strategies: A Fallacy in Cultural Urban Strategies

Two fields of knowledge have been of special importance for the emergence of culture-led urban planning in Norwegian cities: one concerns the understanding of the potential of culture as an economic driving force in urban regeneration, while the other focuses on the emergence of the concept of the “creative class” and has drawn attention to the importance of competence and creativity in urban development. Despite clear connections between the two fields, it may appear that false connections have been made in regeneration strategies in a number of cities. Based on analyses of the culture-led urban strategy of Kristiansand, a small Norwegian city, these knowledge fields are discussed and it is claimed that there seems to be a fallacy in how they are treated in the culture-led urban strategy. The fallacy concerns the way that creativity is equated with culture and further how theories about the emergence of the creative class are equated with a culture industry approach to urban planning. Questions are raised about the potential of culture industry strategies and it is argued that the potential for growth in small cities may not be as great as the public debate and research conducted in large metropolises might suggest.     

The effect of ethnicity and economy upon intergenerational coresidence: northern Norway during the last part of the nineteenth century

During the last part of the nineteenth century, Finnmark province and the northern part of Troms experienced a decline in intergenerational coresidence. This article discusses what impact ethnic affiliation and economic activity had on the living arrangements of the elderly, and what contributed to the change. Logistic regression shows that ethnicity played a role but its effect disappears after controlling for economic activity. Intergenerational coresidence was positively associated with being a married Sámi male with an occupation in farming or combined fishing and farming. As such a person grew older, he was increasingly likely to live separately from an own adult child. This pattern changed toward the end of nineteenth century. By the close of the century, ethnic differences had disappeared, and headship position, irrespective of marital status, was strongly related to coresidence.     

Abortion law reforms in Colombia and Nicaragua: issue networks and opportunity contexts

This article analyses two instances of abortion law reform in Latin America. In 2006, after a decades-long impasse, the highly controversial issue of abortion came to dominate the political agenda when Colombia liberalized its abortion law and Nicaragua adopted a total ban on abortion. The article analyses the central actors in the reform processes, their strategies and the opportunity contexts. Drawing on Htun's (2003) framework, it examines why these processes concluded with opposing legislative outcomes. The authors argue for the need to understand the state as a non-unitary site of politics and policy, and for judicial processes to be seen as a key variable in facilitating gender policy reforms in Latin America. In addition, they argue that ‘windows of opportunity’ such as the timing of elections can be critically important in legislative change processes.     

Dendrochronological Dating of Wooden Artefacts using Photography

Core sampling is normally used for dendrochronological age determination of both timber and living trees. As core sampling can seriously damage artefacts, a photographic method was tried on 29 wooden objects made of Scots pine (Pinus sylvestris L.). These were photographed and tree‐ring sequences for dendrochronological analysis were measured on the photographs in the laboratory. Nine objects could be dated. The undatable objects had few tree‐rings or a non‐matching tree‐ring pattern. The region in Norway where the material had grown could be determined by matching against various regional chronologies.
