Alfabetets användning : Konkret poesi och poetisk artefaktion i svenskt 1960-tal
- 2005
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The subject of this dissertation is the so-called concrete poetry that was written in Sweden during the 1960s and, to a small extent, in the 1950s, by Öyvind Fahlström, Jarl Hammarberg, Åke Hodell, Bengt Emil Johnson, and others. The study is focused on a discussion of the forms and the ways of writing that were explored, but it also gives an account of the aesthetic-historical context – of the expanded field of the arts in the 1960s, of the early avant-garde, of related forms of writing in earlier literature, such as pattern poetry.The readings are oriented toward different aspects of the texts, such as ’kneaded’ words, disruptive syntax, ’algorithmic’ forms and methods, visuality, and sonority. Two key concepts are ’artifice’ and ’materiality’, both of which indicate how the texts discussed complicate a view of poetry as ’pure’ expression of thought and emotion, or as representation of speech or language (in a restricted sense). These writings use the alphabet in an unorthodox way, and they transgress its territory by approaching other arts and other forms of ’writing’.If one of the aims of the study is to analyze the poetical forms and operations at stake, another one is to connect these to a modern ’media age’, and to discuss the impact of media technologies as well as new conceptions and theories of writing, information, and communication (for example, cybernetics) on poetry. This contextualization gives a specific meaning and value to the texts, and paves the way for a series of questions about reading, subjectivity, and political aspects of poetry.

- In the present study we combined interferon (IFN) and hydroxyurea (HU) treatment, intensive chemotherapy and autologous stem cell transplantation (SCT) in newly diagnosed chronic myelogenous leukemia patients aged below 56 years, not eligible for allogeneic SCT. Patients who had an HLA-identical sibling donor and no contraindication went for an allogeneic SCT (related donor, RD). After diagnosis, patients not allotransplanted received HU and IFN to keep WBC and platelet counts low. After 6 months patients with Ph-positive cells still present in the bone marrow received 1–3 courses of intensive chemotherapy. Those who became Ph-negative after IFN + HU or after 1–3 chemotherapy courses underwent autologous SCT. Some patients with poor cytogenetic response were allotransplanted with an unrelated donor (URD). IFN + HU reduced the percentage of Ph-positive metaphases in 56% of patients, and 1 patient became Ph-negative. After one or two intensive cytotherapies 86 and 88% had a Ph reduction, and 34 and 40% became Ph-negative, respectively. In patients receiving a third intensive chemotherapy 92% achieved a Ph reduction and 8% became Ph-negative. The median survival after auto-SCT (n = 46) was 7.5 years. The chance of remaining Ph-negative for up to 10 years after autologous SCT was around 20%. The overall survival for allo-SCT RD (n = 91) and URD (n = 28) was almost the same, i.e. ≈60% at 10 years. The median survival for all 251 patients registered was 8 years (historical controls 3.5 years). The role of the treatment schedule presented in the imatinib era is discussed.

Tidskriftsartikel (refereegranskat)abstract
- Detailed experimental characterization is performed for 1550 nm semi-insulating regrown buried heterostructure Fabry-Perot (FP) lasers having 20 InGaAsP/InGaAlAs strain-balanced quantum wells (QWs) in the active region. Light-current-voltage performance, electrical impedance, small-signal response below and above threshold, amplified spontaneous emission spectrum below threshold and relative intensity noise spectrum are measured. Different laser parameters such as external differential quantum efficiency eta(d), background optical loss alpha(i), K-factor, D-factor, characteristic temperature T-0, differential gain dg/dn, gain-compression factor epsilon, carrier density versus current, differential carrier lifetime tau(d), optical gain spectrum below threshold, and chirp parameter alpha are extracted from these measurements. The FP lasers exhibited a high T-0 (78-86.5 degrees C) and very high-resonance frequency (23.7 GHz). The results indicate that appropriately designed lasers having a large number of InGaAsP well/InGaAlAs barrier QWs with shallow valence-band discontinuity can be useful for un-cooled high-speed direct-modulated laser applications.

The effect of barrier composition on the vertical carrier transport and lasing properties of 1.55-mu m multiple quantum-well structures
- 2006

Tidskriftsartikel (refereegranskat)abstract
- In this paper, the effect of barrier bandgap and composition on the optical performance of 1.55-mu m InGaAsP/In-GaAsP and InGaAsP/InGaAlAs multiple quantum-well structures and Fabry-Perot lasers is evaluated experimentally. Direct vertical carrier transport measurements were performed through strain-compensated multiple quantum-well (MQW) test structures using femto-second laser pulse excitation and time-resolved photoluminescence up-conversion method. MQW test structures were grown with different barrier composition (InGaAsP and InGaAlAs) and barrier bandgap (varied from lambda(g) = 1440 to 1260 nm) having different conduction band Delta E-c and valence band discontinuity Delta E-v, while keeping the same InGaAsP well composition for all the structures. The ambipolar carrier transport was found to be faster in the structures with lower valence band discontinuity Delta E-v. Regrown semi-insulating buried heterostructure Fabry-Perot (SIBH-FP) lasers were fabricated from similar QWs and their static light-current-voltage characteristics (including optical gain and chirp spectra below threshold) and thermal characteristics were measured. Lasers with InGaAlAs barrier showed improved high-temperature operation, higher optical gain, higher differential gain, and lower chirp, making them suitable candidates for high-bandwidth directly modulated uncooled laser applications.

Tidskriftsartikel (refereegranskat)abstract
- The article presents parts of a larger research study which aims to explain how a process-oriented innovation unfolds and develops over time in the health care system in Sweden. It is said that local development teams have a rather broad notion of what it takes to implement the flow model. The theory used to explain the developmental patterns which have been identified in the national and local projects was presented.

"Så gör vi inte här i Sverige. Vi brukar göra så här" : Retorik och praktik i LO:s invandrarpolitik 1945-1981
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The primary purpose of this thesis is to analyse the Swedish Trade Union Confederation, the LO’s, mediated rhetoric, arguments and social and institutional practices in the process of forming the LO’s policy regarding the introduction, incorporation and participation of immigrants in Swedish society in general, the workplace and the trade union movement in the period 1945–1981. The theoretical purpose is to explore how power relations of superiority and subordination based primarily on the categories of class, ethnicity and nation, but also on gender and to some extent generation, have been formed through ideological processes of inclusion and boundary drawing in rhetorical speeches, texts and institutional practices within the framework of an explicit class-based community as the LO constituted. The results demonstrate that the LO had an ambivalent attitude towards labour immigration in an expanding post-war Swedish economy. On the one hand the trade unions accepted that industrial growth and general welfare reforms were dependent on the labour supply. On the other hand, the LO feared that uncontrolled labour immigration would be a disadvantage for indigenous workers, since wages could be kept low and obsolete industrial sectors could be maintained and the “solidarity wage policy” could be endangered because of the influx of migrant labour. Organising the immigrants was a central part of the union movement’s strategy, and the LO also insisted from the very beginning on equal wages and employment conditions between indigenous and immigrant workers to avoid wage pressures. During the second half of the 1960s and the 1970s, the LO repeatedly argued that the scale of immigration should be weighted against factors such as access to work, housing, social services, education and language teahcing. One major argument in the thesis is that within the LO, immigration policy measures were perceived to be a functional “adaptation” of immigrants to the already defined institutions, norms and national culture of the Swedish majority society. Accordingly, the immigrants were expected to adapt themselves to the “normal” Swedish and social democratic way of doing things in a rational and organised manner. During the 1970s, Swedish language training and company introduction with union attendance, translated information bulletins about the Swedish labour market and society, union courses and study circles could be seen as central means in a process of socialisation and “normalisation”. These policy measures were dimensions of a social democratic ideological identity project within the trade union movement, which was constructed as a symbol of the given national order and “the Swedish way of doing things”. The results also demonstrate how class, ethnicity, nation and gender have worked as structuring principles of power and status within the LO.
