Autonomous Åland : A hundred years of borderwork in the Baltic Sea
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This dissertation applies an ethnological and long-temporal view of borders. The region of Åland, being an autonomous and demilitarised island territory under Finnish sovereignty, serves as an illuminative case of the work that goes into keeping borders fixed for two reasons. The region being maritime is the first one, and it being in a betwixt position between a state and a province is the second. The study seeks to explore the borders as cultural entities composed by layers – legal, geographical, political and social – and the processes through which the borders have been anchored. As important are the ways in which the borders extend into everyday life by creating a local order that activities relate to. Borders are hence seen as both objects and sources of actions. Seeing borders as objects of action function as an entry into an exploration of how the borders have been objects of continuous work since their establishment in 1921. The idea of them being sources of actions serves as a window into how the borders in numerous ways have influenced everyday life for inhabitants. In order to analyse the work that goes into borders as well as the actions borders cause, the study explores both the authoritative borderwork and how the borders or their effects have been encountered and handled by individuals who live within. The multifaceted view is achieved through a broad material consisting of archived documents, archived ethnological interviews, participant observations and contemporary interviews, in combination with studies of law and publications. Through the use of the phenomenological concept of practico-inert, the study reveals both how borders are outcomes of incessant human actions, and how they create an undisputable structure for individuals to observe and relate to, but not necessarily obey. In summary, the study contributes with a detailed description of how bordered places are created, and how individuals navigate the structures that they live within.

De små båtarna och den stora flykten : Arkeologi i spåren av andra världskrigets baltiska flyktbåtar
- 2020

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The Baltic states, Estonia, Latvia and Lithuania, were occupied no less than three times during the Second World War. Faced with a reign of terror, the threat of deportation, and compulsory conscription, over 30,000 people fled over the Baltic Sea to Sweden. On their arrival in Sweden, most escape boats were confiscated by the authorities and in 1945 were returned to the Soviet Union.This study, which began as an attempt to find out about the Baltic escape boats that ended up in Sweden, is inspired by a foreign boat in a small fishing harbour on the island of Gotland. My curiosity was piqued when I caught sight of the boat and heard that it had probably been an escape boat.The purpose of this thesis is to establish which, if any, Baltic escape boats survive in Sweden, in which contexts they remain, and to review their state of preservation, as well as to answer the question of their significance for the memory of the escape. It is an archaeology of the escape and its aftermath, based on the surviving escape boats – what the boats say about the escape, what happened to them afterwards, and how people relate to them and their historical legacy today.The study looks at 35 boats that have been described as Baltic escape boats in various contexts. It shows that they are found in a multitude of environments and in a range of different states of preservation. The boats illustrate experiences that few other source materials can convey, in a manner pertinent to the archaeological understanding of flight. In addition, the boats are rare traces of an earlier Estonian coastal culture eradicated by the second Soviet occupation.One of the most important outcomes of the study is the documentation from the survey and examinations carried out. Few of the boats were known outside their local context. A national compilation has been lacking, which has impeded research and ultimately our understanding of the breadth and complexity of the Swedish historical landscape when it comes to ship remains.

Efficient GPU-based Image Registration : for Detailed Large-Scale Whole-body Analysis
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Imaging has become an important aspect of medicine, enabling visualization of internals in a non-invasive manner. The rapid advancement and adoption of imaging techniques have led to a demand for tools able to take advantage of the information that is produced. Medical image analysis aims to extract relevant information from acquired images to aid diagnostics in healthcare and increase the understanding within medical research. The main subject of this thesis, image registration, is a widely used tool in image analysis that can be employed to find a spatial transformation aligning a set of images. One application, that is described in detail in this thesis, is the use of image registration for large-scale analysis of whole-body images through the utilization of the correspondences defined by the resulting transformations. To produce detailed results, the correspondences, i.e. transformations, need to be of high resolution and the quality of the result has a direct impact on the quality of the analysis. Also, this type of application aims to analyze large cohorts and the value of a registration method is not only weighted by its ability to produce an accurate result but also by its efficiency. This thesis presents two contributions on the subject; a new method for efficient image registration with the ability to produce dense deformable transformations, and the application of the presented method in large-scale analysis of a whole-body dataset acquired using an integrated positron emission tomography (PET) and magnetic resonance imaging (MRI) system. In this thesis, it is shown that efficient and detailed image registration can be performed by employing graph cuts and a heuristic where the optimization is performed on subregions of the image. The performance can be improved further by the efficient utilization of a graphics processing unit (GPU). It is also shown that the method can be employed to produce a model on health based on a PET-MRI dataset which can be utilized to automatically detect pathology in the imaging.

Samla samtid : Insamlingspraktiker och temporalitet på kulturhistoriska museer i Sverige
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis is a study of contemporary collecting practices at museums of cultural history in Sweden. The study takes off from two questions: How is this practice of collecting understood at museums of cultural history today, and how are these modes of collecting effected when museums explicitly collect the “present” rather than the “past”? The aim is to examine how the present day has been collected, what modes of ordering were activated, as well as what relational effects contemporary collecting has had on the knowledge-building processes within the practice.The overall theoretical framework of the study primarily stands on sociologist John Law’s understanding of actor network theory. The actor network model is used as a theoretical tool to understand how agency and processes of knowledge production work. In addition, theoretical concepts from memory studies, as well as theories on knowledge building processes, are applied.The empirical material is collected through a combination of interviews and participant observations. Furthermore, archival studies were executed at the Nordiska museet archive.Through four chapters, the modes of ordering the Time, the Collectors, the Objects, and the Ideas are examined. The material analysed shows that the cultural historical “hinterland” that shaped the modern museum have had lasting effects on museum-collecting at large, but also on contemporary collecting practices. However, the reversed is also true: Contemporary collecting often acts as an important tool to make the self-evident position of traditional collecting visible. As the act of collecting activates fundamental ethical and moral questions concerning time, place, and social conditions, the practice has had constant effects on museum work in general. Therefore, without an active and conscious collecting, the content of museum work is in risk of stagnating. It is not only through exhibitions and outreach work that museums should have a contemporary societal awareness, but the collecting practices also deserve a mental presence in public space. Stating this, a continued expansive collecting at museums of cultural history is a necessity, by which the general museum-work is pushed forward and expanded. To collect and record expressions of the same contemporary perspectives is here seen as an active way of dealing with the blinding effects of being in the present.
