Masking Moments : The Transitions of Bodies and Beings in Late Iron Age Scandinavia
- 2007
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis explores bodily representations in Late Iron Age Scandinavia (400–1050 AD). Non-human bodies, such as gold foil figures, and human bodies are analysed. The work starts with an examination and deconstruction of the sex/gender categories to the effect that they are considered to be of minor value for the purposes of the thesis. Three analytical concepts – masks, miniature, and metaphor – are deployed in order to interpret how and why the chosen bodies worked within their prehistoric contexts.The manipulations the figures sometimes have undergone are referred to as masking practices, discussed in Part One. It is shown that masks work and are powerful by being paradoxical; that they are vehicles for communication; and that they are, in effect, transitional objects bridging gaps that arise in continuity as a result of events such as symbolic or actual deaths.In Part Two miniaturization is discussed. Miniaturization contributes to making worlds intelligible, negotiable and communicative. Bodies in miniatures in comparison to other miniature objects are particularly potent. Taking gold foil figures under special scrutiny, it is claimed that gold, its allusions as well as its inherent properties conveyed numinosity. Consequently gold foil figures, regardless of the context, must be understood as extremely forceful agents.Part Three examines metaphorical thinking and how human and animal body parts were used in pro-creational acts, resulting in the birth of persons. However, these need not have been human, but could have been the outcomes of turning a deceased into an ancestor, iron into a steel sword, or clay into a ceramic urn, hence expanding and transforming the members of the family/household. Thus, bone in certain contexts acted as a transitional object or as a generative substance.It is concluded that the bodies of research are connected to transitions, and that the theme of transformation was one fundamental characteristic of the societies of study.

Makt uttryckt i jord och sten : Stora högar och maktstrukturer i Mälardalen under järnåldern
- 2008

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis focuses on power structures in the Mälaren basin during the Iron Age, and how these structures change over time. In the viewpoint of the author, constructing large mounds was an important way for the elite in the Mälaren basin to distinguish themselves from other groups in the region during the relevant period. By studying how the mounds differ in size and contents in relation to the norm, at least two different social strata can be discerned. The lower stratum was more similar to warriors than heads of power, and vice versa. The burial mounds from the Late Iron Age are almost always located in burial-grounds which belong to villages and farms, and which often extend back to the transition between the Roman Iron Age and the Migration period. It was not until the early Vendel period that cremation and mound building became the standard burial practice for the elite in the Mälaren basin. The analysis also reveals that large mounds were built mainly in the early Vendel period (AD 550–700) and the late Viking Age (tenth century).To find out how the elite used the large mounds in their social strategies, the author conducts a landscape-archaeological analysis in which the locations and visual effects of the mounds in the landscape are described and interpreted. The landscape analysis clearly shows that the mound-building elite in the Mälaren basin preferred to have their farms situated close to major communication routes, especially at important junctions in the landscape. The analysis further shows that some of the great mounds served as meeting places for the Thing. On the other hand, the mounds seldom coincide with cult places. The latter are often situated on the periphery of settlement complexes with mounds rather than at the sites of the mounds themselves.Finally, the author sets the results of the landscape analysis in a culture-historical context. The discussion centres on when and why large mounds were built in the Mälaren basin during the Iron Age. In addition, the author discusses the role of the mound-building elite and their relationship to other elite groups in the political development, which ranged from small local dominions in the Migration period to the early medieval Christian kingdom.

Den reformerade världen : Monastisk och materiell kultur i Alvastra kloster från medeltid till modern tid
- 2005
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In 1143 a Cistercian abbey was founded in the parish of Västra Tollstad in the province of Östergötland in Eastern Middle Sweden. The abbey of Alvastra and the role of the Cistercian monasteries in medieval Swedish society forms the main subject of this thesis. This thesis is based on an analysis of architecture, artefacts and graves recovered during the excavations of Alvastra, and analogies are made with the abbeys of Varnhem, Gudhem and Vreta but also with urban and rural areas in the region. The abbeys are studied in long-term perspective, using archaeology to study not only monastic life but the Reformation and post-dissolution periods.The primary results of the thesis concern the later history of Alvastra, which is poorly known from written sources. The archaeological material in many ways highlights the 14th century as an important period in the history of the abbey of Alvastra. New monastic buildings were erected that in both form and function directly related to secular society. The use of international currency increased, as did the use of imported pottery. Burial practices changed, particularily in regards to the spatial distribution of graves. Several if not all of these changes may be interpreted as part of a transformation of the relationship between the abbey and secular society. The relationship between the abbey and secular society became closer, which was manifested in architecture, artefacts and burials. This may be seen as an attempt by the abbey to adapt monastic culture to changing religious ideals, but it caused secular perceptions of the abbey to change.By opening the abbey to seculars and making lay people a part of the Cistercian brotherhood, the monks adapted a traditional structure to changing circumstances. At the same time, the very relationship with the seculars changed. The position and authority of the Cistercians stemmed in large part from their distance and isolation from lay society. Monastic culture did not provide the tools for understanding religious change in terms that allowed the monasteries to survey the consequences of their actions in terms of the social and religious position of the abbey.

- Recent research on identification of cascade systems has revealed some intriguing variance results for the estimated transfer functions of the subsystems. Such structures are common in most engineering applications. Even so, little is known about quality properties for structured estimated models of cascade systems. The objective of this paper is to analyze the underlying mechanism for some non-intuitive variance results when the true subsystems have common dynamics. It turns out that a simple FIR example of two cascaded subsystems can be used to understand the basic issues. The cascade system identification problem for this case corresponds to solving a second order equation in a least squares sense constraining the roots to be real. The difficult case is when the second order equation has double roots (the discriminant Δ is zero), which holds when the transfer functions of the subsystems are equal. In this case a more proper statistical analysis should be done conditional on the sign ofΔ If only the second output signal is used for estimation the result is that Δ > 0 gives estimates with poor statistical properties (variance of order ∂ (1/√N)), while Δ <0 will automatically constrains the roots to be real and double and hence this case gives variance of order ∂(1/N). If both output signals are used for estimation the unconditional variance of the estimate of the first system does not depend, on the average, on the output from the second system. A simulation example shows that the statistical properties also in this case are much better than predicted by average variance analysis if Δ < 0. For this simple example, it is hence possible to monitor the quality of the estimate by studying the sign of Δ. Traditional variance analysis only considers the average effects and hence misses this two mode (good or bad) situation.
