Undersøgelsen af areal‐ og ressourceudnyttelsen omkring udvalgte mindre, marginalt beliggende nordbogårde i Vesterbygdens centrale del fokuserer især på gårdsanlæggenes vegetationsressourcer med henblik på beregning af deres bæreevne og foderværdi.

På grundlag af biomasseberegninger synes en kronologisk og/eller social betinget bebyggelsesekspansion fra “gode” områder mod mere marginale områder at kunne påvises.

Analyser af forholdet mellem græs‐ og husarealer tyder på, at gårde med begrænset græsareal i nærheden kompenserer herfor enten ved at holde flere får eller geder (fremfor køer), som kræver mindre græs som foder og som oftere huses i fritliggende udhuse, eller ved at have større udhuskapacitet til oplagring af hø høstet længere borte fra gårdene.

En veldokumenter et gård bliver brugt som eksempel til beregning af vegeta‐tionspotentialets bæreevne, det faktiske dyreholds størrelse og husstandens størrelse.

Desuden bliver udnyttelsen af højlandet søgt belyst i forbindelse med betragtninger over forekomsten af anlæg og ressourcer relateret til sæterdrift og rensdyrjagt.  相似文献

Through a study of the history of the concepts of wealth and poverty, this paper investigates the onset of a tradition in the conceptual architecture of epidemiological research concerning social differences in mortality rates from 1858 to 1914. It raises the question as to what the concepts of wealth and poverty meant to those who used them and what objects of interventions the conceptual architecture surrounding the concepts enabled the researchers to create. It argues that a transition began in the late 19th century in which an important framework for the understanding of causal relations behind the mortality patterns changed and that this change in turn influenced the scope of what was conceived as relevant objects of intervention.  相似文献

This article investigates the housing experiences of international students in comparison to other newcomers in the mid-sized Canadian city of St. John's, Newfoundland and Labrador, with a focus on how they navigate housing crises. Drawing on recent literature on housing justice, a quantitative survey of 188 participants, and 30 qualitative interviews, the findings reveal that international students and other newcomers are at different stages of their housing careers, have different needs and goals, and are experiencing the affordability crisis differently. Housing discrimination is a pressing concern, especially for international students who are subjected to intersectional prejudice, exploitation by landlords, and amplified challenges due to the COVID-19 pandemic. The article argues for inclusive housing and immigration policies that acknowledge international students as part of the Canadian housing market and ensure their rights to housing.  相似文献

Arsenic has previously been measured in a bone sample of a c. 5-year-old Mesolithic child from Nivaagaard in Denmark yielding an anomalously high value of 13 μg/g. In the present work we show that other individuals at a nearby site also exhibit elevated arsenic levels, whereas individuals from other Mesolithic sites in Denmark are found to have quite low As-concentrations. Several attempts to reveal the source of the arsenic are reported: A railway track near the site, where the railway sleepers were suspected to have been impregnated with As leading to transport or diffusion of As into the adjacent soil; Several food items, the remains of which were found at the site, and one food item not preserved in the excavation, i.e. seaweed. Finally, it is shown that the most likely explanation of the elevated arsenic levels in human bones at Nivaa is diagenesis.  相似文献

The study applies the concept of ‘urban empty space’ as defined by Monica Smith to the adjacent churchyards of St. Alban and St. Canute, the latter being both a cathedral and a shrine for the royal saint, Canute the Holy. The aim is to demonstrate that the churchyard of St. Canute incorporated other temporary functions for the urban society, which subdivided the space into more labile areas or demarcations of use. The demarcations might, according to the concept, become contested areas between various users; thus, the article seeks to identify possible contestants through examining the built environment as well as the artefacts – in the present case, though, limited to the pottery. The article shows that the studied objects can shed new light on the urban empty space of the medieval churchyard. It is also a reminder that urban churchyards are not completely isolated loci of sanctity for the dead but are very much a part of urban life.  相似文献

This paper explores the impact of animal manure application on the δ15N values of a broad range of crops (cereals and pulses), under a range of manuring levels/regimes and at a series of locations extending from northwest Europe to the eastern Mediterranean. We included both agricultural field experiments and areas where ‘traditional’ farming is practised. Our aim is to ground-truth interpretation of δ15N values in archaeobotanical crop remains as evidence of past growing conditions and husbandry practices. The results confirm the potentially radical impact of manuring on δ15N values in cereals, depending on manuring level, but indicate only a slight effect on pulses, which can fix atmospheric nitrogen. The expected geographical trend towards greater δ15N with increasing climatic aridity is not apparent, probably because the growing conditions for crops are ‘buffered’ through crop management. Each of these observations has fundamental implications for archaeobotanical interpretation of δ15N values as evidence of land use practices and (together with analysis of bone collagen/tooth enamel in potential consumers) palaeodiet.  相似文献
