- We experimentally investigate and quantify performance improvement, accounting for multiple bit intervals' joint statistics in filtered equalized on-off keying OC-192 fiber-optic links relying on Viterbi-algorithm-based sequence detection. We demonstrate that the penalty associated with narrow filtering can be alleviated for the most part with an appropriate detection approach.

Indigenous infant mortality in Sweden : the key to the health transition
- 2009
-
Konferensbidrag (refereegranskat)abstract
- The Sami of northern Scandinavia have experienced a positive health development that has brought them from a high-mortality situation two hundred years ago to their present-day low-mortality profile. Their experience is not shared by other indigenous peoples around the world. This study is concerned with infant mortality, a key issue in the health transition process. Long-term infant mortality trends are analyzed in order to compare Sami and non-Sami groups in the area. Data is obtained from the world-unique Northern Population Data Base at Umeå university, and consist of digitized 18th and 19th-century parish records. These complete life biographies include ethnic markers and enable longitudinal studies of causes of death, differences in sex, age-distribution, stillbirths and legitimacy status. The results are discussed from the perspective of the source quality, methodological considerations, the health transition generally in Sweden, and the overall Sami health transition

Indigenous populations and vulnerability. : Characterizing vulnerability in a Sami context
- 2006

Ingår i: Annales de Demographie Historique. ; 111:1, s. 115-132

Tidskriftsartikel (refereegranskat)abstract
- Among the most vulnerable populations of today are the indigenous peoples. They share the experience of colonization with severe implications. Historically thousands of indigenous cultures have ceased to exist. The current article outlines and discusses the conditions from the past to the present that make an indigenous people like the Swedish Sami vulnerable. Until the early twentieth century the Sami were in some respects a demographically vulnerable population. Infants and child mortality were dramatically high, yet the fear of extinction that prevailed among Swedish scientists until the 1940s were never realistic. The Swedish Sami population of today is not living on the brink of extinction but there are still circumstances that are the result of historical events contributing to them being more vulnerable than the majority population of Sweden. The Sami has been reduced due to demographic, socio-economic, cultural and political interference. We argue that the Sami vulnerability of the past, present and future involves changes in statistics, language, traditional economy, religion, relocation/reservation, cultural diversity, educational system, and denial of the right to cultural and political self-determination. These factors all play important roles for the contextualization of indigenous vulnerability and should be considered when studying vulnerability among all indigenous populations.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis focuses on dwelling sites with hearths dating from the period 600-1900 AD, located in the coniferous forest areas of Northern Sweden. The term dwelling sites with hearths refers to sites where stone-lined hearths occur. These hearths are of a type that became very common in Northern Sweden during the first millennium after the birth of Christ.The main aim of this study is to apply environmental archaeological methods to the investigation of dwelling sites with hearths in order to attain new information on the organisation and use of these sites, as well as to discuss and evaluate earlier strategies of settlement and subsistence. For this study, soil chemical survey and pollen analysis methods are used. Soil chemical surveys have been conducted at a total of 13 sites from the period 1000/1100-1900 AD at locations in the inland areas of the counties of Norrbotten, Västerbotten and Jämtland, while pollen analyses have been conducted at 4 sites located in the county of Norrbotten.Interpretations of the results are related to previous archaeological research, surveys and excavations. In addition, historical and ethnographical documentation as well as historical research concerning the conditions in the area during later periods are considered.The results show that environmental archaeological methods can provide information about settlements with hearths that is not normally possible to discern through archaeological surveys or excavations. Regarding the environmental impact at the settlement areas, there are clear differences between different dwelling sites with hearths. These differences seem to be independent of the number of hearths at the sites. Thus, it is not possible to make interpretations regarding these dwelling sites based purely on the number of hearths at the sites. The results also imply that these sites have been part of a settlement system where different types of dwelling sites were in use for shorter periods of time, for different purposes, and by a limited number of people. With the exception of the 17th century church and market place in Arvidsjaur, none of the examined dwelling sites could be interpreted as being a gathering site for a large number of people. Compared to descriptions of the conditions in the Sami area (Sa. Sápmi) during historical periods, this type of settlement pattern is comparable to the Forest Sami settlement pattern of late historical times. Moreover, soil chemical surveys conducted in areas adjacent to a number of hearths show similarities to the Sami hut (Sw. kåta). To sum up, the use of dwelling sites with hearths shows continuity from the 7th century settlements to Sami settlements of the 20th century, with respect to the environmental impact at the dwelling sites. On the basis of these results, it is suggested that a settlement pattern and subsistence similar to that of the Forest Sami economy and settlement of late historical times are characteristic for settlements with hearths and may have occurred as early as 600 AD.
